Custom Trade Partnership Against Terrorism (C-TPAT) is the latest Security Standard created by the U.S. Customs Border Protection (CBP). Post 9/11 measures had to be adopted promptly in order to protect the U.S. borders from terrorist threats. Therefore the CBP devised security measures to be adopted for all companies lined along the supply chain. This program was initially offered to manufactures, importers, ports, liners, and other firms.
