    1. What Is TEU?

    What Is TEU

    A TEU, which stands for twenty-foot equivalent unit, serves as the standard size for shipping containers and is the predominant type employed on cargo ships. Hence, TEUs are alternatively referred to as "unit loads" or "intermodal containers." These containers are 20 feet in length, 8 feet in width, and 8 feet in height. Their primary utility lies in quantifying a ship's capacity or the volume of cargo it can transport. For instance, a vessel carrying 3,000 TEUs is designated as having a capacity of 3,000 TEUs.

    The term "TEU" is also employed to express the quantity of containers being loaded onto or unloaded from a ship simultaneously. To illustrate, if a ship is loaded with 1,000 20-foot containers, the cargo on board is denoted as 1,000 TEUs.

    4. How to calculate TEU? 

    To determine TEU (Twenty-foot Equivalent Unit), it's crucial to have information on the container sizes and their respective quantities. The standard container sizes typically used are 20 feet (referred to as a 20-foot container) and 40 feet (referred to as a 40-foot container).

    How to calculate TEU

    The following steps outline how to calculate TEU effectively:

    🔎 Identify Container Sizes: Standard containers come in 20 feet (1 TEU) or 40 feet (2 TEU) variations.

    🔎 Count the Number of Each Container Size: Tally the quantity of 20-foot containers (equivalent to 1 TEU) and 40-foot containers (equivalent to 2 TEU) you possess.

    🔎 Calculate TEU: Multiply the count of 20-foot containers by 1 (each contributing 1 TEU) and the count of 40-foot containers by 2 (each contributing 2 TEU). Sum the results from both calculations to obtain the total TEU.

    *For example: Let's say you have a container with the following dimensions:

    Length: 40 feet, Width: 8 feet, Height: 8.5 feet

    To calculate the TEU, you need to normalize these dimensions to the equivalent of a 20-foot container. So, for a 40-foot container, the TEU would be:

    TEU = (Length / 20) * (Width / 8) * (Height / 8.5)

    TEU = (40 / 20) * (8 / 8) * (8.5 / 8.5)

    TEU = 2 * 1 * 1

    TEU = 2

    So, the TEU of a 40-foot container is 2.

    You can apply the same formula to calculate the TEU for containers of different sizes. Just divide the length, width, and height by their respective standard values for a 20-foot container.

    Now that you have a thorough understanding of the process, you may calculate TEU by carefully going over the various types in the preceding section and using the formula to get precise results for yourself. In addition, you also need to immediately see the instructions for calculating accurate cubic feet for shipping for your shipments, especially for beginners.

    6. What is the TEU capacity of global shipping vessels?

    What is the TEU capacity of global shipping vessels

    TEUs are a common metric for quantifying and classifying shipping vessels. Major industry players often own vessels exceeding 14,500 TEUs in carrying capacity, while smaller feeder vessels are designed for 1,000 TEU containers or fewer.

    In contemporary maritime operations, a prevalent vessel type is the Post-Panamax, boasting a TEU capacity ranging from 5,000 to 10,000. These vessels vary in length from 820ft to 984ft (250m to 299m). Another noteworthy category is the Neo-Panamax, capable of accommodating up to 14,500 TEUs.

    Among the regularly employed vessel types are Ultra Large Container Vessels (ULCVs), characterized by lengths of up to 300m (984ft) and a TEU capacity exceeding 14,000. The MSC Irina, the largest container ship entering service in 2023 under the Liberian Flag, has an impressive capacity of 24,346 TEUs.

    Beyond the Post-Panamax and ULCV, the industry encompasses smaller feeder ships (1,000 to 2,000 TEUs), Feedermax vessels (2,000 to 3,000 TEUs), and Panamax vessels (3,000 to 5,000 TEUs).

    7. TEU container vs FEU container: What’s the difference?

    TEU container vs FEU container What is the difference

    In the shipping industry, a standard Twenty-foot Equivalent Unit (TEU) measures 20ft (6.1m) in length, 8ft (2.4m) in width, and 8ft (2.4m) in height. Its larger counterpart, the Forty-foot Equivalent Unit (FEU), is double the size, measuring 40ft (12.2m) in length, 8ft (2.4m) in width, and 8ft (2.4m) in height. Essentially, the FEU is akin to the older sibling of the 20ft container, boasting twice the cargo capacity. It's noteworthy that acquiring a single 40ft container is often more cost-effective than purchasing two 20ft units.

    The terms TEU and FEU are employed to indicate cargo capacity. For instance, if a shipment comprises two 20ft containers and one 40ft container, it is classified as four TEUs or two FEUs in total.

    8. Frequently Asked Questions about TEU Containers

    What is a TEU container?

    A TEU, or 'Twenty-foot Equivalent Unit,' is the standardized measurement unit in the shipping industry for gauging the capacity of container ships and terminals.

    1 TEU equals how many tons? (1 teu = ton)

    When converting TEUs to tons, it is important to consider that a TEU measures volume, not weight. Therefore, the weight in tons can vary depending on the density and type of cargo being carried. However, there are general estimates for the average weight capacity of a TEU:

    • Maximum Gross Weight: A standard 20-foot container can have a maximum gross weight of approximately 24,000 kg (24 metric tons). This includes the weight of the container itself, which is typically around 2.3 tons, leaving about 21.7 tons for the cargo.
    • Average Cargo Weight: The actual weight of cargo in a TEU can vary widely. On average, a TEU might carry about 10-11 tons of cargo. This figure is used for statistical and planning purposes but can differ based on the type of goods being transported.

    In summary, while a TEU can carry up to 21.7 tons of cargo, the average cargo weight is typically around 10-11 tons. The specific weight can vary depending on the cargo's density and type.

    How much is a TEU in meters?

    How much is a TEU in meters

    A TEU container is a standard 20ft dry shipping container, measuring approximately 20ft (6.1m) in length, 8ft (2.4m) in width, and 8ft (2.4m) in height.

    How is the TEU of a container calculated?

    To calculate the TEU of a container, measure its length (e.g., for a 40ft container, it would be 40ft or 12.2m). Divide the length by the standard length of a TEU container (20ft): 40ft ÷ 20ft = 2. The result signifies the number of TEUs equivalent to the container. In this example, a 40ft container is equal to two TEUs.

    5. Which account has the largest TEU volume?

    The shipping company with the largest TEU (twenty-foot equivalent unit) volume is Mediterranean Shipping Company (MSC). As of early 2024, MSC boasts a fleet capacity exceeding 5 million TEUs, solidifying its position as the world's largest container shipping line. This significant capacity allows MSC to handle a substantial portion of global container traffic.

    To schedule your consignment on a container ship, it is crucial to comprehend TEU. See Worldcraft Logistics's dedicated website on booking ocean freight for further information on how to book ocean freight and make sure you get the most out of your container space.
