The Secure Chain is a partnership of public and private parties. For the release and collection process via the Secure Chain, the participating deepsea shipping lines/ship agents and container terminals have decided that all data exchange must take place 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.
