Coastal manifest requirement: vessels carrying only coastal goods must submit a prescribed manifest before arrival or departure. The Government requires the person-in-charge or agent of vessels carrying exclusively coastal goods operating from berths used by import or export vessels to deliver a prescribed coastal manifest to the proper officer prior to arrival or departure. The manifest must include vessel and port identifiers, vessel type, ports of discharge, and detailed consignment-level information such as shipper and consignee, cargo description, invoice references, container or vehicle numbers, seals, and weights, together with a signed certification by the master or agent.
