ISA is a voluntary approach to trade compliance that originated from the passage of the Customs Modernization Act (Customs Mod Act) in 1993 as it ushered in an era of new partnership concepts between the importing community and the United States Customs Service (Customs and Border Protection - CBP). The program provides the opportunity for importers who have made a commitment of resources to assume responsibility for monitoring their own compliance in exchange for benefits. The ISA program offers benefits that can be tailored to industry needs and requires that importers demonstrate readiness to assume responsibilities for managing and monitoring their own compliance through self-assessment.
