The Secure Chain is a collaboration between public and private parties. In the preliminary phase, the initiating parties determined that all data exchange within the Secure Chain would be facilitated via the services of Portbase. Of course, shipping lines/ship agents have the option of choosing a different solution for the secure and reliable release of containers. In all cases, the inland operator will however need to submit a pre-notification to the container terminal via Portbase prior to the collection of the container.
