Port community system

A port community system (PCS) is a neutral electronic platform that links the parties in a port (terminals, carriers, forwarders, customs, port authority, inland carriers, and banks) for single-window data exchange. It lets each party submit data once and reuse it, carrying manifests, customs declarations, dangerous-goods notifications, gate and berth appointments, and release messages, usually over UN/EDIFACT and increasingly API and DCSA standards. Operators such as Portbase (Rotterdam), MCP (Felixstowe), and DAKOSY (Hamburg) cut paper handovers and duplicate keying. The PCS sits above any single terminal operating system, which manages one terminal’s internal yard and quay; the PCS connects many actors across the whole port.
