Summary

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.

Customs Duties — Source: USLM XML via OLRC

(a)This section shall apply to all cargo to be exported that is moved by a vessel carrier from a port in the United States.
(b)(1)No shipper of cargo subject to this section (including an ocean transportation intermediary that is a non-vessel-operating common carrier (as defined in section 3(17)(B) of the Shipping Act of 1984 (46 U.S.C. App. 1702(17)(B) 11 See References in Text note below.) 22 So in original. Probably should be “1702(17)(B))))”. may tender or cause to be tendered to a vessel carrier cargo subject to this section for loading on a vessel in a United States port, unless such cargo is properly documented pursuant to this subsection.
(2)For the purposes of this subsection, cargo shall be considered properly documented if the shipper submits to the vessel carrier or its agent a complete set of shipping documents no later than 24 hours after the cargo is delivered to the marine terminal operator, but under no circumstances later than 24 hours prior to departure of the vessel.
(3)A complete set of shipping documents shall include—
(A)for shipments for which a shipper’s export declaration is required, a copy of the export declaration or, if the shipper files such declarations electronically in the Automated Export System, the complete bill of lading, and the master or equivalent shipping instructions, including the Internal Transaction Number (ITN); or
(B)for shipments for which a shipper’s export declaration is not required, a shipper’s export declaration exemption statement and such other documents or information as the Secretary may by regulation prescribe.
(4)The Secretary shall by regulation prescribe the time, manner, and form by which shippers shall transmit documents or information required under this subsection to the Customs Service.
(c)(1)No marine terminal operator (as defined in section 3(14) of the Shipping Act of 1984 (46 U.S.C. App. 1702(14))) 1 may load, or cause to be loaded, any cargo subject to this section on a vessel unless instructed by the vessel carrier operating the vessel that such cargo has been properly documented in accordance with this section.
(2)When cargo is booked by 1 vessel carrier to be transported on the vessel of another vessel carrier, the booking carrier shall notify the operator of the vessel that the cargo has been properly documented in accordance with this section. The operator of the vessel may rely on such notification in releasing the cargo for loading aboard the vessel.
(d)(1)A vessel carrier shall notify the Customs Service of any cargo tendered to such carrier that is not properly documented pursuant to this section and that has remained in the marine terminal for more than 48 hours after being delivered to the marine terminal, and the location of the cargo in the marine terminal.
(2)For vessel carriers that are members of vessel sharing agreements (or any other arrangement whereby a carrier moves cargo on another carrier’s vessel), the vessel carrier accepting the booking shall be responsible for reporting undocumented cargo, without regard to whether it operates the vessel on which the transportation is to be made.
(3)For purposes of this subsection and subsection (f), if merchandise has been tendered to a marine terminal operator and subsequently reassigned for carriage on another vessel, the merchandise shall be considered properly documented if the information provided reflects carriage on the previously assigned vessel and otherwise meets the requirements of subsection (b). Notwithstanding the preceding sentence, it shall be the responsibility of the vessel carrier to notify the Customs Service promptly of any reassignment of merchandise for carriage on a vessel other than the vessel on which the merchandise was originally assigned.
(4)If a single shipment is comprised of multiple containers, the 48-hour period described in paragraph (1) shall begin to run from the time the last container of the shipment is delivered to the marine terminal operator. It shall be the responsibility of the person tendering the cargo to inform the carrier that the shipment consists of multiple containers that will be delivered to the marine terminal operator at different times as part of a single shipment.
(e)Whoever is found to have violated subsection (b) of this section shall be liable to the United States for civil penalties in a monetary amount up to the value of the cargo, or the actual cost of the transportation, whichever is greater.
(f)(1)Any cargo that is not properly documented pursuant to this section and has remained in the marine terminal for more than 48 hours after being delivered to the marine terminal operator shall be subject to search, seizure, and forfeiture.
(2)The shipper of any such cargo is liable to the marine terminal operator and to the ocean carrier for demurrage and other applicable charges for any undocumented cargo which has been notified to or searched or seized by the Customs Service for the entire period the cargo remains under the order and direction of the Customs Service. Unless the cargo is seized by the Customs Service and forfeited, the marine terminal operator and the ocean carrier shall have a lien on the cargo for the amount of the demurrage and other charges.
(g)Nothing in this section shall be construed, interpreted, or applied to relieve or excuse any party from compliance with any obligation or requirement arising under any other law, regulation, or order with regard to the documentation or carriage of cargo.
