The New Normal for Maritime Transportation

The New Normal for Maritime Transportation

Since the lifting of extreme COVID-19 restrictions in Europe, the cost of maritime transport has increased three-fold. Unlike economic cycles of the past, such as the 2008 recession, the consensus in the market is that the price will not return to pre-COVID levels in the foreseeable future. This consensus is in part due to the excess stock leaving China and the lack of containers in the market to meet demand. During the pandemic, shipping companies greatly reduced the capacity of container ships. By the end of 2020, full capacity was put back on the market, however, the demand still exceeds the availability of containers.

According to the Shanghai Containerized Freight Index (SCFI), the cost of freight reached $2,900 for twenty-foot containers in January 2021, which is almost three times the cost at the same time last year. The SCFI reflects the fluctuation of spot freight rates on export container traffic based on the most used trade routes from Shanghai. Furthermore, the cost of the forty-foot container stands at $5,200 as compared to $1,800. An increase in the cost of shipping containers reflects the sharp rise in demand for solid bulks from China (such as cereal and grains).

Unlike European markets now, China can offer stable prices for the next 3 to 5 years, which has allowed it to secure long-term contracts to supply countries around the world. Bulk carriers have also experienced a dramatic increase in prices between May 2020 and January 2021, from $477 to $1,339. The Baltic Dry Index currently stands at $1,339, which reflects a new normal in the price of bulk containers. Since then, the price has fluctuated between $1,150 and $2,000 in a typical cycle.

As a result of the current shortage of capacity of maritime transport, it is recommended that companies book 5 or 6 weeks in advance to reserve space on vessels headed to Asia. Moreover, companies should book even further in advance – 6 to 8 weeks – for routes from Asia to Europe. In the Middle East, Turkey and Africa, it is particularly difficult to reserve space to transport goods, and some transports are not accepting reservations. Routes between Europe and North America/Latin America have slightly more availability, but companies should still reserve space a month in advance.

As mentioned above, routes from east to west (ex. Shanghai to Genova) are much more expensive than routes from west to east due to Asia’s need to hoard capacity. The index of the main maritime transport routes (pictured below) increased from $1,500 to $5,000 between January 2020 and January 2021.

Furthermore, the shortage of shipping containers, and subsequently the dramatic increase in costs, have greatly affected industries in Latin America such as coffee exporters in Colombia. In the past 6 months, the SCFI (Shanghai containerized freight index) on the route between Shanghai and South America has grown from $2,000 to $7,000, an increase that exceeds the index of the routes from Shanghai to Europe and North America. Countries in South America are particularly affected by the shortage due to the fact that transport companies prioritize routes with the highest round-trip cargo. For example, a shipping company would choose to assign a ship to Rotterdam rather than Santos because it will return faster and with more cargo.

Companies are navigating the higher costs by taking structural measures to shorten their supply chain, such as by limiting exports to certain locations. Still, the increase in shipping costs have forced them to reduce their profit margins in the short term. However, economic recovery could cause more firms to increase their prices to reflect the increase in maritime transport costs.

The reality of the “new normal” of maritime transport has greatly accelerated the transition to the use of planes and trains for container transport, especially between China and Spain. The graph below reflects the reduction in the number of shipping containers in transit between 2019 and 2020 (in millions of containers) for Spain. Overall, imports by sea to Spain from China and Hong Kong have fallen by -11.47% million euros between 2019 and 2020, while air and rail imports have increased by 52.49% and 1,088% million euros, respectively.

Based on these numbers, it is clear that many companies have begun to shift away from maritime transport to alternative forms, such as rail transport, in order to optimize their costs. Compared to maritime transport, rail transport boasts quite a few benefits including a reduction in lead times, increased efficiency and, most importantly, cost efficiency. Moreover, rail freight also is the most eco-friendly shipping option in terms of its exhaust emissions.

Since the introduction of express rail services between the EU and China in 2011, rail trade share has increased from less than 1% to 4%. While a vast range of commodities opt for rail transport over maritime transport including mechanical, electronic, vehicle, apparel, households and food, the most common commodities to be shipped by train tend to be higher value goods, time-sensitive goods and fast to market consumer products. Rail imports from China to Europe in 2020 included commodities such as electric equipment, nuclear reactors and boilers, machinery, vehicles, and textile and apparel.

What is the current outlook for the future of maritime transport?

While there are currently sufficient numbers of shipping containers to meet the demand for a normal year, this has not been the case for 2021. The surplus of containers in Chinese ports in March of 2020 and the expectation that trade would fall with the spread of COVID-19 resulted in a reduction of orders for Chinese shipping containers. However, the dramatic increase in demand for Chinese consumer goods in mid-2020 caused the price of shipping containers to increase dramatically. Despite the increase in production of the containers, there continues to be a lack of used containers being returned to China. According to Bloomberg News, the lag in the shipping industry, as well as low inventories, port congestion in the U.S., and increasing consumer demand will likely extend the shortages far beyond the mid to late 2021, despite having moved out of the COVID-19 economy.

Optimizing Picking Systems. PTL vs. PTV

Optimizing Picking Systems

Picking systems describes the process in which a warehouse takes to select and pull items from inventory to fulfill a customer’s order. It is essential for warehouses to find their optimal method for picking that ensures accuracy and efficiency. The cost of labor, materials, technology, and accuracy can all play a crucial role in maximizing their bottom line. Thus, distribution centers are left with different methods to consider – all of which have some advantages depending on one’s needs. For this case, we will analyze three different methods: pick-to-light, pick-to-paper, and voice picking.


Pick-to-paper, also known as label processing, is entirely reliant on the paper orders for warehouse procedures. Typically, this is also paired with digitized methods of information storage via desktop terminals. A warehouse associated completes their tasks listed on pick lists, put-away labels, or other label documents. This process is most optimized for smaller processes and for those operations that cannot afford the large barrier to entry for other systems. Overall, this is a simple method to implement in even the most primitive settings.

However, this is one of the slowest methods of picking with upstream (how information is written in the label) and downstream (scan and verifying via desktop terminal) processes impacting its performance. Due to the nature of recording paper orders, it is impossible for a warehouse to maintain a real-time track of their inventory – dependent on data entries made by other associates. This inefficiency and many points for error make this process difficult to scale into larger settings.

The picture below is a depiction of what pick-to-paper looks like.

Pick/Put-to-Light (PTL)

Pick-to-light systems are among the most popular methods used in distribution centers. This process is much more intuitive, guiding associates via light to the products needed for each order. It is a simple-to-use technology that can support large pick rates. PTL systems are equipped with software that activates light displays for every needed location, displaying the quantity needed for that order. These benefits result in a company’s ability to get an average worker productive quicker and with less down time.

Still, this system is very expensive, technologically complex, and requires a large initial capital investment to ensure functionality. The cost of the software alone, is in the excess of $100,000. Plus, this method cannot be applied to anything other than order selection. This limits the method’s versatility when dealing with receiving, put-away, and cycle counting.

Below is a depiction of what PTL systems look like.

Pick-to-Voice (PTV)

Alongside pick-to-light, voice picking has proven to be one of the most popular methods of picking. For this system, an associate is guided through picking via an audio device that lists its necessary items. Voice picking is an effective method of picking most useful for lower velocity SKUs, full case and pallet picking. It has the distinction of being slightly more accurate PTLs while also being slightly cheaper.

A drawback to voice picking, however, can be seen in its ability to integrate new workers. While training times can be relative short compared to pick-to-paper systems, it limits the distribution center of the kind of worker who can do the job. Language barriers and audio limitations can play a large role in limiting the effectiveness of the method.

Below is a depiction of what a pick-to-light system looks like.

Compiled together is a table between the advantages and disadvantages between the three different methods.

Pick-to-Light (PTL) vs. Pick-to-Voice (PTV)

In this blog, we have established that both options are much better alternatives to pick-to-paper. Both options present a system that is easy to use, has more of an increased efficiency, improves accuracy, and as a result lowers overall cost. However, both systems are more geared towards a bigger scale operation as both systems are expensive to implement. We have put together a list explaining the specific differences between the two below.

  • Training Time / Ease of Use – Both PTL and PTV can reduce training times significantly. On average both systems can cut down up to 50% of the training time needed for pick-to-paper systems.
  • Productivity – Pick-to-Light and Pick-to-Voice systems are roughly the same in productivity. However, PTL systems have an added variability component where cheaper systems can be less productive. PTL systems can do approximately 110 – 350 lines per hour. This is very comparable to PTV systems which can do approximately 300 lines per hour. Still, on average both systems preform 25% better than paper systems.
  • Improved Accuracy – A more mechanized system of picking can reduce human errors. Both PTL and PTV systems allow for an associate to focus specifically on the product, instead of having to worry about labels or interfaces. As a result, PTL systems have an industry average of error at about 4 – 6 per 1,000 picks. PTV systems have an industry average of error between 0.2 – 2 errors per 1,000.

System Cost – Overall, both options are expensive endeavors. Pick-to-light systems attain most of their cost in the software required. PTL systems run at excess of $100,000 with each display costing between $100 and $150.

Pick-to-voice systems have options for how to implement the system. Voice terminals run above $2,500, vehicle mounted terminals run above $3,500, and wearable terminals cost above $2,000. More innovative technologies such as smart glasses are progressively being introduced into this PTV systems for about $800.

In the Real World

Warehouses mostly investigate PTL or PTV when they have reached optimum pick metrics using more simpler technologies such as pick-to-paper. PTL and PTV are mostly reserved for larger corporations looking to further increase productivity, accuracy, and reduce overall costs. For examples, Amazon has reported used PTL systems in their warehouses. This has been due to the language limitations presented by voice directed picking systems.

Meanwhile, the fourth largest pizza delivery chain, Papa John’s has replaced its picking process with voice-directed picking processes. This is especially useful in freezers, where temperatures can make working with hands more difficult.



Regardless of the differences between the three different methods of picking, there is one common denominator between the three of them. When picked, all items need to be scanned to provide management with updated information regarding inventory and movement of goods. Traditionally, this need is supplemented by barcodes – an effective, but a suboptimal method. This is where RFID can play a major role.

RFID (radio frequency identification) is a technology that is comparable to barcoding in terms of keeping track of data stored in a tag/label captured by a device and stored in a database. However, RFID uses radio waves to determine the movement of goods. This means that there is no need for optical scanners and a picker can focus solely on obtaining the right products to fulfill an order. Listed below are some benefits to RFID.

  • Simplifies tracking assets and inventory management.
  • Electronic control/upload of information reduces transcription errors.
  • Provides up-to-date data on inventory, ensuring availability of goods.
  • Saves overall time by automating and optimizing scanning.



RFID can be combined with different methods of picking to further increase efficiency. This where multi-order picking comes in. Multipicking is an effective method of streamlining order picking. This process involves the warehouse associate locating and picking multiple orders at the same time. Multipicking saves time by cutting down the amount of travel time made by the associate. This is mostly ideal for situations where a company must deal with many small orders.

This is where solutions such as Ehrhardt-Partner’s RFID multipicker can save time and cost. This product implements pick-to-light systems for multiple order picking and combines it with RFID technology for simple scanning. The RFID multipicker optimizes both the movement of multiple orders and tracking of goods at the same time.

Overall, pick-to-voice and pick-to-light systems are extremely reliable. These technologies are not new and have been perfected over the course of decades. They serve as reliable systems to increase worker productivity, reduce errors, provide for ease of use, and overall create a return on investment over time. While smaller companies may find pick-to-paper systems more effective and easier to implement, this method should not be considered for companies looking to grow and expand. PTL and PTV systems can be extremely effective in ensuring appropriate picking. As to which is better for you, this would require more extensive research and tailoring to your needs. But either way, both are truly better and modernized for the warehousing issues of today.

Comparing the 3D Printing Methods

Comparing the 3D Printing Methods

When looking at 3D Printing, there are several methods that a company can consider, depending on the needs of a company. For this analysis, three different methods will be considered: Fused Deposition Modeling (FDM), Stereolithography (SLA), and Selective Laser Sintering (SLA).


Fused Deposit Modeling/Filament Fabrication (FDM/FFF)

FDM is a kind of 3D printing technology that melts and extrudes thermoplastic filaments based upon a pre-determined path. It does this by extruding material layer by layer. This technology is the most accessible to the public, smaller companies, and for companies looking to do simple prototyping or seek proof-of-concept modeling. Due to its low barrier to entry, this technology provides parts that are lowest in resolution and accuracy. This method is clean, easy to use, and very office friendly. But FDM suffers from warping tendencies when printing a large flat area, protruding features, sharp corners, and certain materials (ABS).

Price and Labor

The price of an FDM printer ranges anywhere between €250 to upwards of €12,000. For a low-end, consumer personal printer the cost is approximately €250, but is limited to the amount of prints it can make. This version is ideal for at-home 3D printing. If manufacturing is the goal, then an industrial printer is needed – these run upwards of €12,000.

Another factor to consider when running an FDM printer is labor and training needed to use this printer effectively. Luckily for everyone, this printer requires minor training on build setup and machine operation/finishing. Additionally, it requires a laborer to remove the product out of its manual support – however, this can be automated with a soluble system.

Stereolithography (SLA)

SLA is one of the most common forms of 3D printing. This method works by using a high-powered laser to harden liquid resin. Resin is released from a reservoir inside the machine and is added layer by layer to make a 3D model. A good benefit for this technology would be its highly versatile material selection. SLA provides the highest resolution and accuracy. Those looking to keep tolerances tight and have fine details to their 3D model should consider this option. This option is good for those looking to create models for functional prototyping, patterns, molds, and tooling.

Price and Labor

Overall, an SLA printer provides much better results than an FDM printer, but it comes with a much higher price tag – where a machine costs about 10 times a typical FDM 3D printer. SLA printers start with mini versions for personal use at about €200. However, professional desktop printers start at €2,800. These printers have a higher accuracy and bigger than personal printers. They can fill the role of industrial production from a machine the size of a desktop.

Still, the most accurate, largest, and flexible machines in the market are industrial printers. These printers are upwards of €65,000 – with some versions costing over €100,000.

Much like an FDM printer, this machine is very simple to use and setup. However, an SLA printer is much easier to maintain and much easier to obtain a smooth and polished finish to a product. Some could characterize this printer as a plug and play printer. In terms of labor, since this product is formed from a pool of resin, the print needs to be washed and cured – both of which can be automated, especially in an industrial setting. Estimates place the labor needed for curing to be more than 20 minutes, washing 5-20 minutes, and drying at 30 minutes.

Source: 3DNatives

Selective Laser Sintering (SLS)

SLS printing is a technology that uses a laser to sinter together powdered plastic material into a solid structure. This method has been a popular choice due to its low cost per part, high productivity, and for not having support structure. The products provided by SLS can be compared to injection molded parts. This method is best used for companies looking to create products for functional prototyping and customize manufactured parts.

Price and Labor

The price for an SLS printer can be extensively expensive. SLS machines are more optimized for the industrial setting. A benchtop SLS printer, a miniaturized version of an industrial printer, can cost upwards of €8,000. These printers are small enough to sit atop a shop/garage workbench. Industrial printer at €80,000 or more.

However, one area where this printer can be optimized much more than the former two options would be its material reusability. The powder that is not ultimately fused into the mold can be removed and reused for other prints.

Since this printer is a more industrial printer, it requires more training on build setup, maintenance, machine operation, and finishing. However, this is offset by the simple cleaning and removal process of a print. All a laborer must do is collect the unfused powder, remove the print, and restart the device for the next job. This process can also be automated.

Costs of Defects – Effect of Cheap Material

Probably one of the most important factors to consider when choosing to use a 3D printer is the time it takes to obtain a full print and wasted material. The use of poor-quality material, where filler materials and poor spool winds are more likely, can cause a print to fail before completion. A failed print can cost time and material. This would far outweigh the tempting short-term benefits a company can obtain by choosing to opt in for a cheap material.

3DFuel has put together two different scenarios where costs can be potentially different. Scenario 1 presents a normal print completion using a cheap filament. This presents a large overall cost savings in terms of materials and per print price.

However, given a cheap material is more likely to fail a print, they have presented a second scenario. This time, Scenario 2 is given a first print failure at 50% completion, only for it to be rerun and successfully made. The hours sunk into the part and the amount of material multiply by 1.5. However, this will also incur costs in terms labor needed for un-jamming and component repairs.

3D Printing and Injection Molding – Insourcing and Outsourcing

Finally, when a company looks toward insourcing or outsourcing different manufacturing methods, some factors need to be considered. Insourcing, for the most part, has a large barrier to entry due to expensive machinery and establishment of the labor needed. However, insourcing comes with the benefit of economies of scale. As printers and injection molders become more frequently used, the more it produces, the cheaper it is to create products. Listed below are some key differences between insourcing and outsourcing.

3D Printing


  • Benefits
    • Economies of scale makes this process more efficient.
    • Return on investment of high-cost machines increases as more products are made.
    • Fastest lead time as products are produced on a as needed basis.
  • Variable Cost (VC)
    • Labor for appropriate finishing: Washing, Drying, and Curing
    • Technicians needed for appropriate 3D printing.
    • Materials for printing.
    • High-cost machinery needed for printing.

Injection Molding


  • Benefits
    • Economies of scale makes this process more efficient.
    • Overall, injection molding pellets are slightly cheaper than 3D printing material.
    • Lower failure rate than 3D printing, faster production once mold is created.
  • Variable Cost (VC)
    • Labor needed for creation of the mold and running of the injection mold machine.
    • Technicians needed for setting appropriate settings such as temperature, flow rate, etc.
    • High cost of injection molding machines.
    • Pellet materials needed for injection molding.


  • Benefits
    • Lowest barrier to entry as a high-cost machine is not needed.
    • Fast lead time, when compared to injection molding.
  • Fixed Cost (FC)
    • Parts are charged on a per product rate.
    • As more products are produced, rates can be slightly reduced.


  • Benefits
    • Lowest chance of failure and most tailored to a company’s needs.
    • Low barrier to entry if seeking a fast-prototyping mold.
  • Fixed Cost (FC)
    • Parts are charged on a per product rate, but cheaper once a mold is created.
    • Creation of the mold is priced into the cost; this is the most expensive part.


When looking into 3D printing, a company has different options to consider. To summarize, a company must investigate what kinds of print properties they are looking for. If a low accuracy and detailed model is needed, then a cheap alternative such as FDM 3D printing should be sought out. SLA and SLS are a much more accurate methods of printing but suffer from post processing needs and higher costs. Another factor to consider would be the effect of cheaper materials and the risk a company takes if it were to cause prints to fail.

Outsourcing and Insourcing can also prove to be large cost contributors to both methods of manufacture. A company can avoid either fixed or variable costs by weighing the benefits that each method can provide. It is ultimately up to the capability of a company to determine if high barriers to entry, economies of scale, or risk play a large factor in production of their products.

Purpose and competitive advantage of CW and FTZ

Purpose and competitive advantage of Custom Warehouse and Free Trade Zone

What is the purpose of a Customs Warehouse? Free Trade Zone?

The purpose of a customs warehouse is to provide companies with the chance to store imported goods under customs control while deferring the payment of import duty and taxes. These items can go through non-transformative kinds of processes including breaking bulk, grouping packages, sorting, grading, and repackaging. However, there are other types of customs warehouses that can be sought after depending on the needs of a company; examples are listed below.

  • Private Warehouse: A warehouse owned and operated by an organization or corporations. These entities dictate who can store and operate in their warehouse.
  • Public Warehouse: A warehouse more geared toward import, export, manufacturing, distribution, and short-term distribution needs.
  • Automated Warehouse: Modernized warehouses are now equipped with mechanization (either in a small or large scale) to reduce labor costs, streamline functions, increase productivity, and reduce errors.
  • Temperature Controlled Warehouse: This storage option is equipped to handle imports that require more specialized handling. This is usually coupled with other specifications such as air conditioning and humidity control.
  • Distribution Center: This warehouse specializes on receiving products from suppliers and shipping them to customers. Products moving into a distribution center are not handled with storage in mind, but more towards breaking down, aggregation, resorting, and shipment.

Meanwhile, a free trade zone is a customs-free international zone where goods can be handled, manufactured, reconfigured, and reexported without intervention from customs.


Are there restrictions for access in a Customs Warehouse/Free Trade Zone?

Storage Time

In general, both a customs warehouse and a free trade zone allow for companies to store their products indefinitely. However, a custom warehouse has more flexibility and options that can be tailored to the needs of a company. For example, if a company is pursuing a short-term storage option to obtain enough time for customs procedures to be completed, they may choose to use ADT Warehouses (Temporary Warehouse Deposit). Importers may only keep their products stored for a period up to 45 days for maritime imports and 20 days for other types of imports.

Restricted Goods and Flexibility

When it comes to restricted goods, a customs warehouse is more accessible for those looking to store restricted goods (live animals, meat/dairy products originating outside of EU, firearms, etc.). A customs warehouse can allow for these products to come in given the clearing from customs. A free trade zone, however, these items are generally not allowed entry.

However, if a company is looking for a more accessible environment for their products, they should look towards a free trade zone. While a customs warehouse can provide many advantages, a company must be much more involved with the national customs agency. This limits the movement of goods and places it at the discretion of customs – both with approval and business hours. In a free trade zone, you are free to move products around this special tax area and at any time of the day. Additionally, a customs warehouse can only admit international products. A free trade zone can admit both domestic and international products.


How does RPA complement these types of warehouses/zones?

RPA (Inward Processing Regime) is a regime that allows companies to process, modify, destroy, or repair non-Union goods. This regime can be implemented inside EU customs territory without paying import duties or VAT.

RPA can be extended to companies willing to import and manufacture within their own warehouses or within customs manufacturing warehouses. However, it should be noted that this regime must be authorized by the local customs agency after an application is submitted. When it comes to free trade zones, they benefit from not being within customs territory and therefore are not subject to the charges imposed on value added manufacturing.


What kinds of competitive advantages are there when using Customs Warehouses/Free Trade Zones?

Specialized Storage

Overall, customs warehouses and free trade zones allow for the storage of large quantities and are equipped with long term storage options such as temperature and humidity controls. This optimization is ideal for companies looking for more specialized forms of storage and for those who need to move around large quantities of goods.


Of course, with large movement of goods, a large risk – especially in terms of security. However, for both customs warehouses and free trade zones, the customs agency lays down security requirements at each installation to avoid theft and tampering. Additionally, customs warehouses also offer the companies the service of inspecting and taking account of goods. For a company operating in a free trade zone, this responsibility falls on them.

Streamlined Customs Processing

Customs processing can be a complicated and long process, especially for those who are not experienced enough to understand every little detail of regulation. Customs warehouses are prepared for this by having more trained personnel that deal with customs processing. They facilitate the storage and movement of goods to ensure legality. This challenge is exacerbated when imports are moved into a company/retail warehouse. For this case, it is recommended to look for a customs broker.

Free trade zones, on the other hand, do not offer this service. However, this disadvantage can be offset by avoiding customs overall. Given a free-trade zone’s international trade designation, any business occurring there can take advantage of a consolidated, simplified customs process. One place where this can be seen in when a company exports to the United States. In a free trade zone, you can take advantage of a consolidated weekly entry. Here, you are required to pay up to $528.33 a week for any number of entries into a free trade zone. Outside of this area, you are required to pay this amount for every entry made. This streamlined custom procedure can reduce the amount a company pays in fees. It can even reduce customs brokage fees by reducing the number of entries needed to be filed.


Finally, an outsourced warehouse can serve as a good liability assurance for any lost/damaged/stolen goods. Since the responsibility of security lies on the third party, this can ensure that an incident will not hurt a business’s bottom line.



Overall, both options for exports are very similar in qualities. Both options serve to smooth out the trade process. However, when deciding on which option to use, it is important to consider all the intricacies of both options. If a company is more interested in maintaining revenue by reducing customs processing times and costs and outsourcing security, then a free trade zone may prove to be more beneficial. A customs warehouse would be ideal for those looking to outsource liabilities, distribute products, and ensure a better control on the taxes they pay.

3D Printing vs. Injection Molding

3D Printing vs. Injection Molding

One of the biggest developing technologies emerging in the modern era is 3D printing, an additive form of manufacturing that seeks to alter the way companies go about producing new products and possibly even manufacturing itself. As like any other new technology, as it develops, the overall usage price drops to a point of commercial viability. Today, 3D printing has found itself a market where it can be used appropriately to facilitate prototyping and even reduce lead times. It has the potential to accelerate production and improve productivity. However, the question remains as to whether this technology can replace current conventional manufacturing methods. To explore this idea, 3D printing will be compared to a conventional manufacturing method, injection molding.

Injection Molding and 3D Printing in Manufacturing

Injection Molding plays a big role in producing parts in large volumes and moving a product into mass production. This process has been a staple in the industry for its ability to reduce waste when compared to CNC machining – a process where a block of metal is cut away to create a product. When running an injection molding process, the only waste obtained would be from the runner, sprue, and gates. If a company uses a slightly more expensive thermoplastic material, then this waste can be remelted and reused for other injection molds. Overall, by reusing and reducing waste, this can serve to reduce overall material costs.

However, it must be understood that the mold presents itself as a high entry cost to this manufacturing method. Creating the mold can range anywhere in between $1,000 to an excess of $80,000, depending on the complexity of the model. Before any kind of injection molding can be done, the mold must be manufactured. This alone can lead to long lead times and could delay company productivity until the model can be made. However, this process becomes more economically efficient as production is increased. As economies of scale take its effect, this process gradually reduces the cost per part manufactured. This makes this manufacturing methods ideal for large production companies and for those can afford to pay the high barrier to entry.

The benefits from economies of scale can be amplified for more complex products. With injection molding, a more complex part is coupled with a more complex mold, this of course, causes the cost to rise. Meanwhile, 3D printing has no added costs associated with increasing complexity but lacks the benefit of cost reduction per part as manufacturing increases. As we can see in the infographic below, injection molding proves to be more cost effective in large scale operations. It can also be noticed where the cross over point is for the two processes, showing at what cost per part and what production level the two processes are equal. It can also be concluded that 3D printing is more cost efficient at lower levels of production. This case uses polylactic acid (PLA) as an analysis.

Rex Plastics, an American plastic manufacturer has put together a graph detailing the cost estimates for each mold. Rapid prototyping tooling is a fast and cost-efficient way to carry out low-volume injection molding for several types of plastic parts. Insert tooling combines metal and plastics, or multiple combinations of materials and components into a single mold. This improves wear resistance, tensile strength, conductivity, and allows for tighter tolerances. High production tooling allows for molds to be specifically designed for high production. This means tighter tolerances, endurance, high automated wear maintenance provisions, and process control capabilities. Cost estimates for the three options are listed below.

For smaller companies, 3D printing can serve as a good alternative. By either outsourcing or purchasing your own 3D printing machine, the product needed can be printed in a matter of a day or two and can quickly be rushed into production or to wherever needed in the logistics train. Additionally, this process is known for its very low waste turnover with each product manufactured. 3D printing is an accurate form of manufacturing a product, however it does run with a higher risk of failure. Certain estimates place this at around 20%. Due to the high rate of failure, there is a risk of wasting material and time.

A Cost Analysis: Car Frame
Based upon market prices for common materials used for 3D printing and injection molding, we can obtain a preliminary estimate for the cost of materials. Listed below is the cost for each material in terms of euros per metric ton.

Using a cost calculator from Xometry, a company focused on the production of products, we can determine a general estimate for how much a part would cost for both injection molding and 3D printing. For this analysis, a car fender with a 1643.32 cm3 volume will be analyzed with three separate manufacturing techniques – HP Multi Jet Fusion, SLS 3D printing, and injection molding.

SLS printing is a technique that uses a laser as the power source to sinter powdered material such as Nylon or Polycarbonate, often resulting in a rougher but stronger part. HP Multi Jet Fusion is relatively newer way to 3D Print. For this process, printing is done layer by layer as a fusing agent is added with each pass. For both 3D printing studies below, Nylon 12 30% Glass Filled is used as the base material, resulting in 3.22 kg of material used. The results are listed below.


Overall, there are more than just cost factors to consider when deciding to use either 3D printing or injection molding. These factors include time, finish, accuracy, and quantity. It is up to the company to determine what methodology is best in producing what they need. However, the question of whether a company can substitute either forms of manufacturing is clear. 3D printing can serve as a good compliment rather than a substitution. It can be well-used for rapid prototyping or low-scale production levels. It can serve as a proper bridge between the two and ultimately optimize the production cycle of a company.

Customs Warehousing and Free Trade Zones - Case Study

Customs Warehousing and Free Trade Zones – Case Study

When it comes to assessing the lowest costs, a product must be selected in order to obtain more concrete figures. A good case study to analyze costs associated in assembling and distribution of products would be automobiles. In this case study, three different scenarios will be taken into account. The first scenario will consider a finished product moving into a customs warehouse for either export into the U.S. or distribution into Spain. The second scenario would be importing an intermediate product such as steel into a free trade zone that will be used for assembling a car. The third scenario will focus on a hypothetical situation where every part of the production of a car occurs within Spain.

Case Study 1: Finished Product (Export/Import into a Customs Warehouse)

Consider having the car assembled and produced outside of Spain. Initially, this product avoids Spanish regulations and taxes. Once the product is exported to its destination, then the duties and taxes will be subject to the discretion of the final country of destination. Take a Spanish company that wants to access the European or American market with its line of cars, this company will want to store supplies until the market deems it necessary for use. Once an opportunity presents itself, the company will begin distribution of supplies depending on where it is necessary.

To export a finished car to the U.S. the company must pay a 10% VAT tax and a 2.5% tariff. The trader will also incur a merchandise processing fee of anywhere between a minimum of $27.23 to a maximum of $528.33 per entry in a customs warehouse at a rate of 0.3464% of value of a product. Finally, another cost incurred would be the harbor maintenance fee at a rate of 0.125% of the product value. For imports into Spain, the tax process is much simpler – with only two major components to worry about, a 21% VAT tax and a 10% tariff. To put this in numbers, €1,000,000/$1,000,000 worth of cars will be used as an example. The breakdown for numbers is listed below.

This goes hand in hand with the amount of storage costs that a company incurs a day. This process takes place preceding exporting from Spain or following arrival to the customs warehouse. To maintain cars within a customs warehouse, the average cost of storage is approximately €0.15 in Madrid and €0.2267 in Barcelona.

Case Study 2: Intermediate Product – Steel (Export/Import into a Free Trade Zone)

In this case, a company is to import an intermediate product that will ultimately be used in the assembly of the product. This may be a favorable option for companies that wish to take advantage of a free trade zone’s flexibility towards processing. A free trade zone would allow for transformative processing that a customs warehouse would not.

Taking a core component in the production of a car, steel, a rough estimate can be obtained over how much cost a company may incur. For steel being imported into Spain, from the U.S., the product will be subject to no taxes until a final product is manufactured. Once a car is assembled, the product is then subject to an additional 21% VAT tax rate and a 25% tariff. For steel exported into the U.S., the product will be subject to a similar merchandise processing and harbor maintenance fee mentioned in case 1. After a car is produced, the product is then subject to an additional 10% VAT tax. This process would be repeated for all the other differing products needed in a car. This car would then be subject to a storage fee preceding exports to another country or arrival to Spain prior to distribution. To maintain the cars inside a free trade zone, a company must pay anywhere in between €0.01054 – €0.0924 per cubic meter per day. In order to compare between the intermediate and final product, a €1,000,000/$1,000,000 worth of steel will be analyzed with destination or origin to the United States. Once again, the numbers are listed below.

Case Study 3: Production in Spain

For this case, the entire process of putting together a car is done inside Spanish/EU customs zone. Ignoring labor costs and fixed costs, we can determine the effect of VAT taxes on intermediate processes of the car. For this process, a manufacturer must acquire raw materials and pay a 21% VAT tax on the amount purchased. This cost is then pushed down onto the next manufacturer as a new sale price is set. VAT, at this point, is taxed on the gross margin at each point of the manufacturing, adding to the total VAT tax. Finally, this total VAT is then pushed onto the consumer, who ultimately pays for it once a final price is set. Once again, the additional VAT is added due to the gross margin proposed by the retailer.

For a complicated process of putting together a car, it may prove to be too expensive to go about this route. There are too many intermediate points of value added and compound with each middleman. It is always much better to pay VAT once, rather than several times. While the cost of VAT is ultimately recuperated at the sale of the product, it may prove to dig into a company’s cash flow when moving large quantities of products.


Overall, there are three different approaches a company can take to go about processing and creating a car. Based on the options presented, the first two options seem to be the most cost-effective option. However, this is dependent on the product being produced. For a company looking to cut costs while also continue processing, a free trade zone proves to be the most cost effective. A company focused on storage and logistics, then a customs warehouse is more effective.

Customs Warehousing and Free Trade Zones

Customs Warehousing and Free Trade Zones

Taxes and Cost

In the current free market, there are some options an exporter may take to ensure they produce their products efficiently and cost-effectively. For a company considering moving their products abroad, there are some main concerns that a company must consider moving into an international market. The most important factor to a company’s profit in this case would be import taxes, value added taxes, and commercial policy measures. This is where both customs warehouses and free trade zones play an important part in trade. Both customs warehousing and free trade zones provide an opportunity for exporters to defer these taxes and provide special treatment for goods and storage.

In fact, by deferring value added tax until the point of exportation, businesses have reported up to 25% to 30% overall savings. This is due to the high levels of VAT taxes the Spanish government imposes on imports. With the VAT tax rate being at approximately 21% for most goods, the overall total customs estimate totals between 20%-30%. The total customs estimate is just the combination of costs due to duty, VAT tax, and customs fees. In the United States, this burden is less with total customs rate imposed is approximately 10-20%. These are savings that can be allocated into other areas of logistics for the distribution of cargo.

Overview of Differences

While both storage options offer a good tax incentive, there are other variables that make either one of these options more fitting for the right company. For exports in the United States, there is a time limit of five years set for goods to be held in bonded warehouses, whereas they can be held indefinitely in a free-trade zone. However, for this time limit is not present in the European Union. This opportunity allows for companies to delay introduction of a product to market until there is greater demand. Listed below are some important distinctions between the two:

  • Domestic Reach – Custom warehouses allow for quick domestic response to domestic demand.
  • Restricted Goods – Restricted goods are only limited to customs warehouses.
  • Processing – Only processing that does not fundamentally change the product is accepted in customs warehouses. Manufacturing can take place in free zones.
  • Allowable Exports – Custom warehouses are exclusive to only foreign exports while free trade zones are open to both foreign and domestic goods.
  • Duty Payment – Payment of duty is made once the goods leave the customs warehouse or exits non-custom territory. However, movement can be made between free zones.
  • Control of Goods – Local customs officials are in control and supervision of stored goods in customs warehouses and their movement. In contrast, free trade zone officials have full control of the stored product.
    • However, customs warehouses carry the added benefit of offering logistical services for transport, packaging, waste management, etc.
  • Ease of Withdrawal and Removal – Withdrawal from a customs warehouse is done with permission from Customs and must be withdrawn in its entirety. A “as-needed” withdrawal requires special permission. Goods in free trade zones can be withdrawn more freely.

Here is a table summing up the differences between the two options:


Overall, the choice behind what kind of storage option is right for your company is based on what the end goal and necessity is. A customs warehouse is geared more towards a company that has more manufacturing capabilities. A free trade zone is more geared towards international trade. As it stands, it may seem to the average consumer that the more cost-effective and freeing choice is a free zone. However, a company must acknowledge the savings on taxes and its comparative savings on logistics. If the goal is to focus on a more domestic market with an international product, a place where supply needs to be satiated at a moment’s notice, then a customs warehouse would likely be a better option. This allows for less customs red tape and for a more dynamic procedure. For a more international focused trade, free trade zones may prove to be more cost effective. Ultimately, the goal is to reduce the amount of cost a company incurs and maximizing logistical output.

Market Research

As concluded in our last report, there are 4 key aspects triggering a constant decrease in our clients’ sales. The approach to these key aspects is to increase commercial activity and sales.

Our research continued focusing on some of the most consumed vegetables in Germany: potatoes, strawberry, cabbage, salat, asparagus and cucumber, identifying shrinking and growing markets.


Due to climate change, farms may lose productivity, and new fruits/vegetables may appear and compete against the traditional ones. Also, society is changing, newer generations are moving to urban sites, easing a land concentration in fewer farms.

Change of crops

As shown in the graphs analyzed by Ahead Analytics, nearly most of them have a decresa in the production over the last 20 years.

Basically, the geographic part where the vegetable itself was being harvested, is a key point to analyze for commercial purposes. Furthermore, a company with this analysis go ahead with the further steps: find commercial partners and focus on customer experience.


The agriculture industry is affected by many intangible aspects such as climate change or change in customers behavior. However, it is relevant to analyze the existing market and the main crops that are sold in the domestic market. Therefore, we can state that focusing on the customer (final and intermediary) should be the key aspect.

Agriculture - Case Study

Market Research

Markets Dynamics is about constant change in several directions: clients’ needs change, competitors move their offers, new technologies are created and new trends show up. In June 2020, we developed a market research for a mature market, Germany, focusing on fertilizers as the main product. The challenge: understand the market current trends and find new niche dealers to expand sales.


We concluded that there are 4 key aspects triggering a constant decrease in our clients’ sales: Climate change, Agritech solutions, Substitute products and change of consumer behaviors. The approach to these key aspects is to increase commercial activity and sales.

Climate change

The temperatures in Germany have had an important increase in the last couple of years. As we can see in the graphs, the last two years have been the hottest and driest in a 60 year timeline:

Companies considering adapting their existing strategies to climate changes, must change their mindset and start developing new products that may satisfy clients’ needs. In this project, the current climate evolution suggests that climate in Germany is going to get even more severe, hotter, and drier, resulting in decreasing planted surfaces.
