Scoping language
Importer Security Filing Importer. For purposes of this part, Importer Security Filing (ISF) Importer means the party causing goods to arrive within the limits of a port in the United States by vessel. For shipments other than foreign cargo remaining on board (FROB), the ISF Importer will be the goods' owner, purchaser, consignee, or agent such as a licensed customs broker. For immediate exportation (IE) and transportation and exportation (T&E) in-bond shipments, and goods to be delivered to a Foreign Trade Zone (FTZ), the ISF Importer may also be the party filing the IE, T&E, or FTZ documentation. For FROB cargo, the ISF Importer will be the carrier or the non-vessel operating common carrier. For the purposes of this part the United States Postal Service is not an ISF Importer. Regulations related to the transmittal of advance electronic information for inbound international mail shipments are set forth in 145.74 of this chapter.
