Introduction to the weight of shipping containers
Listed below are the three most common weights for shipping containers.
The first two are the Tare weight and the Gross weight. If you need to determine which one you need, see the descriptions below. You will also find the sizes of shipping containers, and how much each one weighs.
Then, compare the two figures so you know which container will best fit your needs. When considering the size of your container, consider your payload weight and how heavy the cargo is.
Despite their size, shipping containers can vary a great deal in weight. Containers can be very heavy or light, depending on the type of container and the construction.
A 10-foot dry container, for example, is usually much heavier than a 20-foot one, but the interior space and doors are smaller. In addition, high cube containers can be even heavier than a 20-foot container.
Here are some things to consider when figuring out how much your container should weigh.
The weight of shipping containers is provided by the manufacturer's post-manufacturing process. Shipping containers are tested to determine seaworthiness and to comply with ISO standards.
The interior walls of the container are not structural, but the roof and floor are. The weight of a container is a major factor in determining the overall cost of shipping.
For industrial applications, a shipping container is often the best choice. Shipping companies often use shipping containers to store equipment, furniture, or office supplies.
The tare weight of a 40ft shipping container is around 8,554 pounds, with a gross weight of 57,196 lbs. A forty-foot shipping container is middle of the road in sizing. For your projects, a forty-foot dry shipping container is a good size.
The weight of a shipping container depends on the size and type. Standard shipping containers are ten, twenty, and forty feet in length, with a cube height of forty feet.
You can also order special sizes, such as 10-foot containers, which will change the answer. So, before you buy a shipping container, consider the size of the cargo. If you plan to transport your goods by sea, make sure to check their gross mass first.
Shipping containers are made of box girders with walls that provide rigidity and crush strength. A standard stacking configuration will consist of seven or eight containers.
If you are using supercargo services, the container weights are monitored by a loading computer and gantry. In addition, new facilities use real-time updates of weights from gantries.
In some cases, shipping containers can weigh more than their maximum.
In the past, shippers have misdeclared the gross weight of containerized cargo, with devastating consequences. Misdeclared gross weight has resulted in accidents throughout the supply chain.
In particular, massive damage caused by overloaded shipping containers is directly related to misdeclared gross weight. The International Maritime Organisation (IMO) has introduced regulations to address these issues.
Among the new amendments is the Verified Gross Mass Amendment, which requires shippers to verify the stated gross mass of each container before stowing it on board.

In addition to the gross weight, shipping containers have a net weight. The net weight, on the other hand, is the weight of the items inside the container minus the weight of packaging materials or pallets.
This difference is important in understanding the net weight of shipping containers, as the actual weight of goods inside is not the same as the net weight of the shipping container.
However, it’s important to note that the net weight of a shipping container doesn’t include the weight of packaging materials or pallets.
Tare weight, or the empty weight, is the weight of the container when it is unloaded. This is often referred to as “unladen weight” or ‘unloaded weight‘.
Tare weight is sometimes used in place of the gross weight, but is less accurate and often reflects the actual weight of the entire truck or shipping container. While the tare weight is a useful way to compare the weight of shipping containers, it’s also an important measurement when it comes to choosing the right one.
The size of a shipping container plays a significant role in its overall logistics. A 20-foot container has a payload weight of approximately 4,915 pounds, while a 40-foot container has a payload weight that reaches 67,200 pounds.
Although these numbers vary, the size of your container will ultimately determine its overall weight. Moreover, the weight of a 40-foot shipping container can be as large as a small car.
The Verified Gross Mass (VGM) of a shipping container is the total weight of the container, including the cargo, bracing, and dunnage. This weight is mandatory under the Safety of Life at Sea (SOLAS) convention and must be included in the shipping document, instruction, or separate communication.
The Verified Gross Mass Amendment (VGMA) requires that the shipper verifies the stated gross mass of the container before it is loaded. This process ensures that the declared mass is a true reflection of the actual gross mass of the packed container.
It is easy to download the file template, which includes the information necessary to calculate the payload of the shipping container.
Shipping containers are built to standardized sizes, making loading and packing easier and more efficient. The payload weight of a container is marked on its door and wall.
The container’s rating is the maximum weight that can be safely carried by the container. A 20-foot dry cargo container has a rating of approximately 24,000 kg. A 40-foot container, meanwhile, has a rating of 30,480 kg, or 67,200 pounds.
Shipping containers are designed with solid steel shells for durability and protection. A steel frame ensures the container's structure and durability for many years.
The Verified Gross Mass (VGM) of shipping containers is also an important consideration for inland movement and export compliance.
An overloaded or unbalanced shipping container is a danger to both the ship itself and general road safety. That’s why the Verified Gross Mass (VGM) of shipping containers is mandatory for overseas transport.
Another common misconception is that the weight of a shipping container is determined by its capacity. Overweight containers can negatively impact the stability of the ship and contribute to accidents and citations.
In order to avoid such costly mistakes, the International Maritime Organization (IMO) adopted amendments to SOLAS, or the Safety of Life at Sea Convention, which requires the shipping company to ensure that its containers are legally of the correct weight. This amendment is effective July 1, 2016.
Sizes of shipping containers
The weight of shipping containers can vary. The average container weighs between six and seven thousand pounds, about two and a half times more than the average car. The longer the container, the more it weighs.
The actual weight depends on the manufacturer and type of container. The length, width, and height of the container all contribute to its weight. For more precise weight information, consult the manufacturer’s website or check the weigh scale at your port of shipment.
The smallest shipping container size is the 10 ft. standard container, which measures 10 feet long, six feet wide, and eight feet high. Only Container One offers collapsible containers of this size. This size is great for both varying storage needs and highly portable storage.
A twenty-foot dry container weighs around two thousand pounds, and the inside dimension is nine feet long, seven feet wide, and five feet high.
Choosing the right size shipping container for the job is important, as the weight of your cargo must not exceed its maximum payload.
Higher-cube variants of shipping containers have slightly less payload weight, while smaller-cube containers have slightly less payload capacity.
The “true” weight of a container is called Verified Gross Mass (VGM), which includes the tare weight of the shipping container and its cargo, as well as any periphery contributors, including drainage, blocking, and dunnage.
Shipping container sizes are also affected by location. Large container shipping companies have their own standards to adhere to, so there is an opportunity to find a suitable size and weight. You can choose many different companies in Montana, Nevada, and Arizona.
The most common sizes of shipping containers are 20' / 40' and forty-five feet, although you may need a bigger container for larger cargo. The tare weight will vary according to the factory where the container was made. You can find more information on the ISO 668 Standards website.
ISO container dimensions are an important factor in choosing the correct container for your needs.
While most containers are made to strict standards for strength and safety, you might need a shipping container of an odd size. These containers are often manufactured to exceed the minimum standards.
This may cause additional costs. Fortunately, manufacturers strive to meet these requirements. And with their low prices, shipping containers are widely available. The only problem is identifying them.
