Automated Commercial System and the Automated Broker Interface

The Automated Commercial System (ACS) is used by CBP to track, control, and process all goods imported into the United States. 

A key component is the Automated Broker Interface (ABI), which allows qualified participants to electronically file required import data with Customs. ABI is a voluntary program available to brokers, importers, carriers, port authorities, and independent service centers.

CBP is currently working to transition cargo processing to the Automated Commercial Environment (ACE). ACE is being developed as the primary, modernized system through which the U.S. government will track, control and process all imported and exported goods. As CBP processing is transitioned to ACE, the technical requirements for transmitting data to ACE via ABI will be posted on CBP.gov under the ACE web page.
