(U.S. Customs) A part of the U.S. Customs’ Service Automated Commercial System, controls quota levels (quantities authorized) and quantities entered against those levels. Visas control exports from the country of origin. Visa authorizations are received from other countries and quantities entered against those visas are transmitted back to them. Control of visas and quotas simplify reconciliation of other countries’ exports and U.S. imports. See Automated Commercial System; visa.
