What is the difference between ISF 10 and ISF 5. Who is responsible for each type?

Under the ISF rule, before merchandise arriving by vessel can be imported into the United States, the “Importer Security Filing (ISF) Importer,” or their agent (e.g., licensed customs broker, freight forwarder), must electronically submit certain advance cargo information to CBP in the form of an Importer Security Filing. This requirement only applies to cargo arriving in the United States by ocean vessel; it does not apply to cargo arriving by other modes of transportation.

ISF-10 requires containerized cargo information, for security purposes, to be transmitted to CBP at least 24 hours (19 CFR section 149.2(b)^[1] before goods are loaded onto an ocean vessel headed to the U.S. (i.e. mother vessel, not feeder vessel) for shipment into the U.S. 10+2 is pursuant to section 203 of the SAFE Port Act, and requires importers to provide 10 data elements to CBP, as well as 2 more data documents (Container Status Messages and the vessel's Stow Plan). This is filed by the “Importer Security Filing (ISF) Importer,” or their agent (e.g., licensed customs broker, freight forwarder).

ISF-5 filing is required for Foreign Importers which goods are either FROB (freight remaining on board) which makes a stop at the U.S. before their final destination of arrival to the foreign port of unlading. For foreign cargo remaining on board (FROB), the ISF Importer is the carrier. 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 which is the carrier is the party filing the IE, T&E, or FTZ documentation.
