Automated Manifest System (AMS) is designed by U.S. Customs to facilitate cargo arrival information and release information between the Steam Ship Lines, Airlines and Rail Carriers for shipments destined to or transiting the United States. AMS information works in conjunction with the ABI system to help customs to identify low risk shipments thus allowing for faster, electronic customs clearance.
AMS information must be transmitted to US customs before the cargo leaves the origin country. Failure to file AMS information will result in monetary penalty. Air AMS information is transmitted directly by the airlines. Sea AMS can be transmitted by carriers or NVOCC's with the appropriate bonds.
