CSC (Convention for Safe Containers) is the international agreement for safe containers. All containers that are used for international transport must comply with the requirements of this agreement. New containers are CSC inspected at the factory after which a CSC plate is affixed to the container doors. This plate is valid for five years and contains information about the container, such as the type of container, the manufacturer, the date of manufacture, the serial number, weight, and the plate’s expiration date. The container must be CSC inspected by an authorized company no later than five years after the first inspection.
