Automated Manifest System (AMS)

BACK TO INSIGHTS

The Automated Manifest System (AMS) is a critical electronic information transmission system operated by U.S. Customs and Border Protection (CBP). Required primarily for air and ocean shipments entering the U.S., AMS filings provide detailed cargo data to ensure national security. This guide explores the definition of AMS, its fee structures, and how it differs from the Automated Commercial Environment (ACE) in modern logistics operations.

What is the Automated Manifest System (AMS)?

The Automated Manifest System (AMS) is an electronic transmission portal operated by U.S. Customs and Border Protection (CBP) to facilitate cargo inventory control and release notification. Established as a security measure, AMS requires logistics providers to submit detailed information about cargo entering the United States before it arrives at the port of entry.

Scope and Application

AMS is integral to the security framework of U.S. supply chains. It allows customs officials to identify potential risks associated with air and ocean shipments before the physical cargo reaches U.S. soil. The system mandates that carriers, freight forwarders, and NVOCCs file manifest data within specific timeframes to avoid penalties.

The Role of AMS in Air vs. Ocean Freight

While the term "AMS" is frequently used as an industry umbrella term for all electronic information transmission, its technical application varies by mode of transport:

Air Freight: AMS is the primary system used for electronic air manifests.
Ocean, Truck, and Rail: While historically associated with AMS, electronic manifests for these modes are increasingly handled through the Automated Commercial Environment (ACE). Specifically, ACE is designated for truck, rail, and sea manifests, though the terminology "AMS filing" persists in industry vernacular.

AMS Filing Fees and Compliance

Compliance with AMS regulations involves financial considerations for logistics stakeholders. An AMS fee is typically charged per Bill of Lading (BOL) or Air Waybill (AWB). The responsibility for covering this fee falls upon either the client or the supplier, depending on the Incoterms and service agreement negotiated.
