CSI: Container Security Initiative

CSI logoAs the single, unified border agency of the United States, U.S. Customs and Border Protection's (CBP) mission is extraordinarily important to the protection of America and the American people. In the aftermath of the terrorist attacks on September 11, 2001, U.S. Customs Service began developing antiterrorism programs to help secure the United States. Within months of these attacks, U.S. Customs Service had created the Container Security Initiative (CSI).

CSI addresses the threat to border security and global trade posed by the potential for terrorist use of a maritime container to deliver a weapon. CSI proposes a security regime to ensure all containers that pose a potential risk for terrorism are identified and inspected at foreign ports before they are placed on vessels destined for the United States. CBP has stationed teams of U.S. CBP Officers in foreign locations to work together with our host foreign government counterparts. Their mission is to target and prescreen containers and to develop additional investigative leads related to the terrorist threat to cargo destined to the United States.

The three core elements of CSI are:

  • Identify high-risk containers. CBP uses automated targeting tools to identify containers that pose a potential risk for terrorism, based on advance information and strategic intelligence.
  • Prescreen and evaluate containers before they are shipped. Containers are screened as early in the supply chain as possible, generally at the port of departure.
  • Use technology to prescreen high-risk containers to ensure that screening can be done rapidly without slowing down the movement of trade. This technology includes large-scale X-ray and gamma ray machines and radiation detection devices.

Through CSI, CBP officers work with host customs administrations to establish security criteria for identifying high-risk containers. Those administrations use non-intrusive inspection (NII) and radiation detection technology to screen high-risk containers before they are shipped to U.S. ports.

Announced in January 2002, CSI has made great strides since its inception. A significant number of customs administrations have committed to joining CSI and operate at various stages of implementation.

CSI is now operational at ports in North America, Europe, Asia, Africa, the Middle East, and Latin and Central America. CBP's 58 operational CSI ports now prescreen over 80 percent of all maritime containerized cargo imported into the United States.
