C-TPAT (Customs-Trade Partnership Against Terrorism) certification audit service is an in-depth, third-party assessment of a company’s supply chain security practices. The audit is designed to ensure that a company meets the security criteria established by U.S. Customs and Border Protection (CBP) as part of the voluntary C-TPAT program. The goal of a C-TPAT audit is to identify any security vulnerabilities in the supply chain. After the audit, the third-party service provides a detailed report, often including a corrective action plan to address any weaknesses and help the company improve its security measures to meet C-TPAT standards.
