ACE and Automated Systems

CBP automated systems electronically support the facilitation of importing and exporting goods. By the end of 2016, the Automated Commercial Environment (ACE) will become the Single Window - the primary system through which the trade community will report imports and exports and the government will determine admissibility. Through ACE as the Single Window, manual processes will be streamlined and automated, paper will be eliminated, and the international trade community will be able to more easily and efficiently comply with U.S. laws and regulations.

CBP has established the following mandatory use dates for transitioning to ACE:

Automated Commercial Environment


ACE is CBP's software implementation of the “single window” vision. As ACE features are deployed, manual processes will be streamlined and automated, paper will be eliminated, and the international trade community will be able to more easily and efficiently comply with U.S. laws and regulations. ACE also provides a single, centralized access point for the trade community to connect with CBP and its Partner Government Agencies (PGA) called the ACE Secure Data Portal.


As ACE features are developed and deployed, corresponding capabilities in the legacy ACS will be retired. For more information, visit the ACE Features page.

To learn how to start filing to ACE via EDI or to apply for an ACE Portal Account, visit the Getting Started with CBP Automated Systems page.

Legacy Systems Automated Commercial System (ACS): CBP’s legacy system for filing import data electronically. ACS is used to electronically track, control, and process goods imported into the United States. CBP is scheduled to decommission all core trade processing capabilities in ACS by 2016.
