The Importer Security Filing (ISF) and Additional Carrier Requirements took effect for ocean cargo arriving in the U.S. on January 26, 2009. This regulation, also known as "10+2," was implemented to enhance security measures by requiring importers to submit advance cargo information to U.S. Customs and Border Protection (CBP). The ISF requires details about the shipment, including the importer, consignee, and specific merchandise details, to allow CBP to assess risks associated with incoming cargo.

Prior to the effective date of this regulation, there were no comprehensive requirements in place that ensured advance notice of cargo arriving in U.S. ports, which is essential for maintaining security protocols. The implementation of the ISF was a significant step towards improving the U.S. government's ability to monitor and control maritime imports, particularly after the heightened security concerns following events such as September 11, 2001. The other dates presented do not align with the official implementation timeline of the ISF regulation.
