## Highlights

Cargo containers present significant security concerns given the potential for using them to smuggle contraband, including weapons of mass destruction. In January 2009, U.S. Customs and Border Protection (CBP), within the Department of Homeland Security (DHS), implemented the Importer Security Filing (ISF) and Additional Carrier Requirements, collectively known as the 10+2 rule. Collection of cargo information (10 data elements for importers, such as country of origin, and 2 data elements for vessel carriers), in addition to that already collected under other CBP rules, is intended to enhance CBP's ability to identify high-risk shipments. As requested, GAO assessed, among other things, (1) the extent to which CBP conducted the 10+2 regulatory assessment in accordance with Office of Management and Budget (OMB) guidance, (2) how CBP used information it collected and assessed to inform its efforts to implement the 10+2 rule since January 2009, and (3) the extent to which CBP has used the additional 10+2 data to identify high-risk cargo. GAO analyzed relevant laws, OMB guidance, and CBP's 10+2 regulatory assessment, and interviewed CBP officials.
