Because of the fact that carriers could not know exactly what would have been loaded into the containers, they add this expression on the face of the bills of lading that they have issued in order to protect themselves.

A carrier or a forwarder has no knowledge of the contents of the container unless the container is stuffed by the carrier, forwarder or their agents.
