"This strategy was developed in response to Sections 201 and 202 of the SAFE Port Act (PL 109-347, 120 Stat. at 1901, 1903, October 13, 2006) which require the development of a strategic plan to enhance the security of the international supply chain, including protocols for the expeditious resumption of the flow of trade following a transportation disruption or transportation security incident... This strategy identifies critical nodes where security efforts achieve the greatest impact across the breadth of the international supply chains. Action at these nodes (such as the Secure Freight Initiative), coupled with end-to-end programs (such as the Customs-Trade Partnership Against Terrorism), provides for truly layered security. The implementation of this strategy requires the combined efforts of DHS agencies, other government agencies and the development of partnerships with industry, foreign governments, and international organizations such as the World Customs Organization and the International Maritime Organization. The international supply chain is owned by an amalgam of private sector interests and regulated by multiple international, national, state, and local government jurisdictions. This document delineates the supply chain security roles, responsibilities and authorities of government bodies within the United States."
