Automated Commercial System

Overview
The Automated Commercial System (ACS) is the comprehensive system used by the U.S. Customs and Border Protection to track, control, and process all commercial goods imported into the United States. ACS is widely recognized as one of the world's most sophisticated and integrated large-scale business-oriented systems. Through the use of Electronic Data Interchange (EDI), ACS facilitates merchandise processing, significantly cuts costs, and reduces paperwork requirements for both Customs and the importing community.
