Definition & Explanation

The Importer Self-Assessment (ISA) Program is a voluntary compliance initiative run by U.S. Customs and Border Protection (CBP), offering participating importers operational benefits in exchange for demonstrated, sustained customs compliance. Enrollees commit to making their customs processes transparent through internal audits, documented control systems, and regular self-reviews, building a verifiable compliance record over time. CBP rewards this proactive approach with reduced physical cargo examinations and faster clearance. The program suits mid-sized to large importers with consistent trade volumes, where predictability and speed directly affect operating costs. While related to the Customs-Trade Partnership Against Terrorism (C-TPAT) programme, ISA focuses specifically on trade compliance rather than physical supply chain security.
