Container Weights and Overweight Containers

heavy shipping container

Attempting to ship an overweight container can incur heavy costs to a shipper by a shipping line. Shipping containers have several notifications on them for weights; which one makes the container overweight?

As a shipper, it is important to know this information when planning the number of containers that are needed to ship your cargo.

CSC Safety Approval Plate

On every shipping container usable for overseas shipping there is a CSC safety approval plate. These plates contain information about the shipping container. They also confirm that the container has been inspected by the proper shipping agencies and is safe for sea shipping use.

The CSC plate contains a lot of data on it. This includes who owns the container, specifications on the container such as testing weights and how much can be stacked on top of it. It also includes the most important part of information needed: The Maximum Gross Weight.

The Maximum Gross Weight

Maximum Gross Weight is the value that we are really concerned with when we are talking about the weight that a container can carry. This includes what the container is allowed to carry, as well as the weight of the container itself.

If a container has a maximum gross weight of 80,000 lbs., it means the weight of the cargo plus the weight of the container must not exceed a value of 80,000lbs. If the container data on the CSC plate says that empty weight is 10,000 lbs., you may only load 70,000lbs of cargo into the container.

Overweight Containers and Incorrect Declaration of Weight

Any container that exceeds the maximum gross weight can be flagged by the shipping line and incur an additional charge. This not only includes cases where the maximum gross weight is exceeded, but cases where the weight declared is different than the actual weight of the container.

Weight is a very important issue to shipping lines, as very careful calculations are done to make sure that what is being shipped is legal and safe. Overweight and incorrectly declared containers can not only endanger workers moving them around, they could possible endanger other cargo and cargo workers.

Proper Weight is Everyone’s Responsibility

As a shipper you must work very closely with your shipping department to make sure that the weight you wish to ship is the actual weight of the cargo. When that information is given to your industrial packing company, they will select a container that is rated to handle your cargo.

They will in turn relay this information to your shipping line. Any miscommunication in this chain can lead to additional costs for you.
