Understanding the meaning of the labels on container doors

Shipping containers are used to transport goods and products all around the world. These containers have become an integral part of international trade and commerce, and they can be found in ports, terminals, and on transport vessels worldwide. One of the most important aspects of shipping containers is the markings found on their doors. These markings contain vital information about the container’s origin, destination, and contents. In this article, we will explain how to have a clear understanding of the labels found on the doors of shipping containers.

What are Shipping Container Doors?

Shipping container doors are the entry and exit points of the container. They are typically located on the end of the container and are made of heavy-duty steel. These doors are designed to be strong and secure, to protect the contents of the container during transport. They are also designed to be easy to open and close, to ensure efficient loading and unloading.

Understanding the Markings on Shipping Container Doors

The markings on shipping container doors provide valuable information about the container’s contents, origin, and destination. These markings are typically made up of a combination of letters, numbers, and symbols. Understanding these markings can help shippers and consignees to ensure that the container is loaded and transported correctly.

ISO code

The first thing to understand is the ISO 6346 code. This is a standard code used to identify shipping containers worldwide. The code is made up of four letters, followed by seven numbers, and an additional check digit. The four letters represent the owner of the container, the next six digits are the serial number of the container, and the last digit is the check digit, which is used to ensure the accuracy of the code.

understanding the Markings on Shipping Containers: Placards, Weight, and Destination

The next thing to understand is the markings on the door itself. The most important markings are the placards and labels that indicate the contents of the container. These labels are typically color-coded, with each color representing a different type of hazard. For example, red placards indicate a flammable or combustible material, while yellow placards indicate a reactive or oxidizing material.


Another important marking is the gross weight of the container. This is typically indicated on the door, along with the tare weight (the weight of the empty container) and the payload weight (the weight of the contents). This information is important for determining the load capacity of the container and ensuring that it is loaded correctly.

Finally, there may be additional markings on the door that indicate the container’s origin and destination. These markings may include the name of the shipping line, the port of origin, and the port of destination. This information can be helpful for tracking the container during transport and ensuring that it arrives at its intended destination.
