Shipping Container Markings
Here are all the different markings provided on an ISO container.
Container Number
The primary identification marking on the door is the container marking which has been specifically allotted by the ISO. The number is unique for everyone in order to identify every container to its owner; the number is registered for the records with Bureau International des Containers (BIC), Paris.
It consists of 7 number and 4 letters and follows the order like this: ABCD 123456 7. The first 3 letters are the Code for the Owner of the container and the 4th letter provides the container category. The first 6 numbers are the serial numbers for the container and the 7th number is called the check digit. This is used to validate if the owner or product group code and the registration number have been accurately transmitted.
ISO Code
Underneath the container number is the ISO code which consists of 2 letters and 2 numbers. The 2 letters indicate the type of container it is for example:
- GP – General Purpose (without ventilation)
- VH – General Purpose (with ventilation)
- SN – Named Cargo
- BU – Dry Bulk Cargo
- HI – Insulated
- UT – Open Top
Plus, many more. The 2 numbers indicate the size of the container, the 1st number stating the length and the 2nd number stating the width.
Approved Classification society label
After being tested for compliance with the ISO standards by an approved classification society, it is presented with an approved classification society label. This means it can be used for transportation and the label of the class is provided on the end door of the container.
Certifications
Certifications achieved by the container are required to be displayed using plates. An example of this is a Container Safety Convention (CSC) plate which indicates that the container has been tested and inspected by approved authorities; it states details of the owner/s and other technical specifications.
Owner’s Logo
The shipping container will display the vendor’s logo/name on the end door.
Weights & Payload
Details of the weight capacity the shipping container holds will be marked in the end door:
Tare Weight – The weight of an empty container
Payload Weight – Maximum cargo weight an approved ISO container can carry
Gross Weight – Total weight of container and cargo
Capacity in Volume
The cubic capacity or the volume of the container is marked in the end door.
Warning and Operational Signs
Depending on the type of container and the cargo it will be holding, it may have various warning labels. For example, a heightened container or hazardous cargo will both need warning labels.
