The Automated Commercial Environment (ACE) is the United States’ centralized digital system for processing imports and exports. To move goods across the U.S. border, U.S. Customs and Border Protection (CBP) and partner government agencies require importers and exporters to use ACE to provide detailed information. This enables CBP to collect tariff revenue, control imports, and enforce regulations. ACE is also known as the U.S. “Single Window” because it provides a single, centralized access point connecting CBP, Partner Government Agencies and the business community.
