Automated Commercial System (ACS) and Automated Broker Interface (ABI) CATAIR

ACS is used by CBP to track, control, and process all goods imported into the United States. A key component of ACS is the 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. Currently, more than 96 percent of all entries filed with CBP are filed through ABI.

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 under the ACE webpage.
