Markings on a shipping container (II)

Posted by Rasa

Those, who want to transport cargo in shipping containers, need to know what different markings on the container mean. In the last month’s blog we explained the position and meaning of container’s number, owner’s logo, ISO code, weight and payload. The remaining markings are described in this blog post.

Approved Classification society label. Before the container is used, it is tested by the classification society to determine whether it is suitable for seaworthiness and compliance to the ISO standards. Classification societies are not public bodies; they set and maintain technical standards for ships, marine containers and offshore structures. The list of classification societies can be found HERE. This marking can be found on the back door of the container.

Volume or cube. Indicates the cubic capacity or volume of the container. Marking is also found on the back door.

Warning and Operational Signs. Different warning labels and signs can be found on the container, depending on its type and/or cargo. For example a heightened container will contain the height or warning stripes on the top part of the container. Similarly, a container carrying hazardous cargo will carry a warning sign about the type of hazard or cargo associated with it. There is also a sign on the container that warns of the risk of electric shock.

Certifications. The different certificates that the container holds are displayed with plates. E.g.:

CSC plate: Container Safe Convention sign indicates that the ISO container was inspected and approved by the authorities responsible for the container’s safety. It also contains information about the owner and other technical specifications: date of manufacture of the container, identification number, maximum gross mass, permissible load, test load value and so on.

ACEP or Approved Continuous Examination Programme: this is a container safety program wherein the container under it has to undergo an extensive inspection in a container depot every 30 months of its service. Container owner updates ACEP every 10 years.

We hope that the information and explanations about container’s markings will be useful. If you have any questions about containers, please contact us.
