Automated Commercial System (ACS)

(U.S. Customs) The ACS is a joint public-private sector computerized data processing and telecommunications system linking customhouses, members of the import trade community, and other government agencies with the Customs computer.
Trade users file import data electronically, receive needed information on cargo status, and query Customs files to prepare submissions. Duties, taxes, and fees may be paid by electronic statement, through a Treasury-approved clearinghouse bank. ACS contains the import data used by Census to prepare U.S. foreign trade statistics. ACS began operating in February 1984 and includes: (1) the Automated Broker Interface, (2) the Census Interface System, (3) the Automated Manifest Systems, (4) the Bond System, (5) the In-Bond System, (6) the Cargo Selectivity System, (7) the Line Release System, (8) the Collections System, (9) the Security System, (10) the Quota System, (11) the Entry Summary Selectivity System, (12) the Entry Summary System, (13) the Automated Information Exchange, (14) the Antidumping/Countervailing Duty System, (15) the Firms System, (16) the Liquidation System, (17) the Drawback System, (18) the Fines, Penalties, and Forfeitures System, and (19) the Protest System.
