Supply Chain Security: Feasibility and Cost-Benefit Analysis Would Assist DHS and Congress in Assessing and Implementing the Requirement to Scan 100 Percent of U.S.-Bound Containers

A letter report issued by the Government Accountability Office with an abstract that begins "U.S. Customs and Border Protection (CBP), within the Department of Homeland Security (DHS) is responsible for, among other things, the security of cargo containers shipped to the United States. In fiscal year 2008, 611 ports shipped a total of 9.8 million containers to the country. The 9/11 Commission Act (9/11 Act) requires 100 percent of U.S.-bound cargo containers to be scanned by 2012, and CBP has begun implementing the Secure Freight Initiative (SFI) to address this requirement. GAO was requested to assess CBP's efforts to implement the 9/11 Act requirement. This report addresses (1) CBP's progress at the initial ports participating in the SFI program, (2) CBP plans to implement SFI, (3) the extent to which CBP has estimated costs and conducted a cost-benefit analysis of 100 percent scanning, and (4) any challenges to integrating 100 percent scanning with existing container security programs. GAO reviewed operating procedures for the SFI ports and analyzed cost data. GAO also visited six of the seven original SFI ports and spoke to officials from CBP, foreign governments, and private industry.
