Title 19 › Chapter 4— TARIFF ACT OF 1930 › Subtitle SUBTITLE III— ADMINISTRATIVE PROVISIONS › Part II— Report, Entry, and Unlading of Vessels and Vehicles › § 1431a
Requires shippers to give complete shipping paperwork before export cargo is loaded on a U.S. port vessel. The shipper must give the carrier (or the carrier’s agent) a full set of documents no later than 24 hours after the cargo is delivered to the marine terminal, but in no case later than 24 hours before the ship leaves. What counts as a full set depends on whether an export declaration is required. If one is required, give a copy of it or, if filed electronically, the full bill of lading and master shipping instructions with the Internal Transaction Number. If no declaration is needed, give an exemption statement and any other items the government requires. The government will set rules for how to send this paperwork to Customs. Terminal operators cannot load cargo unless the vessel carrier says the paperwork is complete. If cargo stays at the terminal more than 48 hours without proper paperwork, the carrier must tell Customs where it is. Undocumented cargo left that long can be searched, seized, and forfeited. Shippers who fail to provide required paperwork can face civil penalties up to the cargo’s value or the actual transport cost, whichever is greater, and must pay demurrage and other charges while Customs holds the goods. Other laws and rules still apply.
