In principle, participation in the Secure Chain constitutes an agreement between the shipping line/ship agent and the shipper/forwarder (as the release-to-party). It is up to the shipper/forwarder to involve the subsequent links. In view of the responsibility each party bears in terms of security and reliability, no logistics party can factually ignore the Secure Chain though. Authorities have also expressly urged shipping lines/ship agents to take expeditious measures for the benefit of society. Once a container has been released via the Secure Chain, it must run through the Secure Chain until collection at the terminal.
