ACE and Automated Systems

CBP automated systems facilitate the electronic importing and exporting of goods. By the end of 2016, the Automated Commercial Environment (ACE) will becomemandatory dates 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 trade community will be able to more easily and efficiently comply with U.S. laws and regulations.

Below you will find an overview and links to more information on: ACE, ACE transition efforts and mandatory dates, training materials, technical reference documentation, outreach efforts, and support resources.

Transitioning to ACE

CBP is working to complete and deploy core trade processing capabilities in ACE. As part of this effort CBP has established a series of mandatory use dates for transitioning to ACE. For full details on the transition please visit our page on ACE Mandatory Use Dates, or for details on Partner Government Agency efforts - including pilots - please see the PGA Integration section of our ACE Feature page.
