Definition & Explanation

The TEU (Twenty-Foot Equivalent Unit) is the universal capacity measure in container shipping, derived from the dimensions of a standard 20-foot ISO container. It gives carriers, terminals, and freight forwarders a common metric for comparing vessel and yard capacity: a 40-foot container counts as two TEU. Tracking these units means monitoring their exact location, handling status, and utilization at every stage of the supply chain—from the shipper's gate through transshipment ports to final delivery. Technologies used include GPS transponders, RFID tags, electronic seals, and direct portal access to carrier and terminal operating systems. For shippers and forwarders, this real-time visibility underpins exception management, connecting cargo coordination, and document reconciliation.
