Title 19 › Chapter CHAPTER 4— - TARIFF ACT OF 1930 › Subtitle SUBTITLE III— - ADMINISTRATIVE PROVISIONS › Part Part II— - Report, Entry, and Unlading of Vessels and Vehicles › § 1431a
All exported cargo moved by ship from a U.S. port must have the right shipping papers before it can be given to a carrier for loading. Shippers (including companies that book cargo but do not operate ships) must give a complete set of documents to the carrier or its agent no later than 24 hours after the cargo arrives at the marine terminal, and in no case later than 24 hours before the ship departs. If an export declaration is required, the shipper must provide a copy or, if filed electronically in the Automated Export System, the bill of lading and master shipping instructions with the Internal Transaction Number. If no declaration is needed, the shipper must give an exemption statement and any other items the Secretary requires. The Secretary will set the exact rules for how to send these papers to Customs. Terminal operators cannot load cargo unless the carrier says it is properly documented. If undocumented cargo stays in the terminal more than 48 hours after delivery, the carrier must tell Customs where it is. The booking carrier must report undocumented cargo even when another carrier operates the ship. Undocumented cargo left over 48 hours can be searched, seized, and forfeited. Shippers who break the documentation rule can be fined up to the cargo’s value or the actual shipping cost, whichever is greater, and must pay demurrage and other charges while Customs has the goods. Terminals and carriers may place a lien for unpaid charges. These rules do not remove any other legal obligations.
