The Automated Manifest System (AMS) of the US Customs & Border Protection (CBP) is a combination of a cargo release notification system and an imported goods inventory regulation system. A critical component of the Automated Commercial System (ACS), it works with other components such as the National In-bond Control Program, the Cargo Selectivity System, and the Automated Broker Interface system of the ACS to ease clearance and movement of goods.

The Automated Manifest System is intended to make it easier to file shipping documentation before cargo arrives in the US, thus speeding the flow of goods. This reduces paperwork for Customs and carriers, as it eliminates in-bond documentation and paper manifests. Participants in AMS get a range of benefits that include shorter holding time for cargo, better communication and greater control.
