Prompt used
Import sequence: the vessel arrives and the terminal discharges the container and updates the port community system. The customs broker files the bill of entry; customs assesses it and the importer pays duty online. The shipping line releases the delivery order after freight charges are paid. Customs gives out-of-charge. A trucker books a gate slot, the terminal loads the container, and the gate records gate-out.
