What Is Automated Manifest System (AMS) Filing?

The Automated Manifest System (AMS) is an electronic cargo reporting system administered by U.S. Customs and Border Protection (CBP). AMS requires carriers, NVOCCs, and authorized filing parties to electronically transmit cargo manifest information before shipments arrive in the United States.

​

AMS serves as one of CBP's primary cargo security and trade enforcement programs, providing advance shipment visibility that helps customs officials identify potential security risks and improve cargo screening procedures.

Today, AMS is used across multiple transportation modes, including ocean, air, rail, and truck cargo operations. Within the international shipping industry, AMS is most commonly associated with ocean cargo manifest filings.

 

Why Was AMS Created?

Prior to electronic filing systems, cargo manifests were often submitted manually after arrival, limiting the government's ability to assess security risks before cargo reached U.S. ports.

AMS was developed to:

• Improve cargo security

• Enhance customs enforcement capabilities

• Increase shipment visibility

• Streamline cargo processing

• Reduce paperwork requirements

• Support advance risk assessment

 

By receiving cargo information before arrival, CBP can better identify high-risk shipments and facilitate the movement of legitimate trade.

 

Who Must File AMS?

AMS filing responsibilities vary depending on shipment structure and transportation mode.

Organizations commonly involved in AMS filings include:

• Ocean Carriers - Ocean carriers transmit manifest information associated with vessel operations and master bills of lading.

• Non-Vessel Operating Common Carriers (NVOCCs) - Licensed NVOCCs frequently submit House Bill of Lading information and maintain AMS filing responsibilities for shipments under their control.

• Freight Forwarders - Freight Forwarders often utilize AMS filing systems when managing international shipments on behalf of customers.

• Customs Brokers and Authorized Agents - Certain authorized parties may assist importers and transportation providers with compliance and filing management.

​

What Information Is Included in an AMS Filing?

AMS filings typically include shipment information such as:

• Shipper details

• Consignee information

• Bill of lading numbers

• Cargo descriptions

• Container numbers

• Vessel information

• Port of loading

• Port of discharge

• Routing information

​

The filing party is responsible for ensuring that information submitted to CBP is complete, accurate, and transmitted within applicable deadlines.

​

​

AMS Filing Deadlines

Timely submission of cargo information is a critical component of AMS compliance.

For ocean cargo shipments, CBP generally requires cargo manifest information to be transmitted before cargo is loaded aboard the vessel at the foreign port of origin.

​

Missing filing deadlines can create operational disruptions, including:

• Cargo holds

• Delayed vessel loading

• Increased customs scrutiny

• Shipment examinations

• Customer service issues

​

Maintaining accurate shipment data and streamlined filing processes is essential for avoiding compliance problems.

Common AMS Compliance Challenges

Many logistics providers face challenges when managing AMS filings manually.

Common issues include:

• Managing Large Shipment Volumes - As shipment activity increases, manually processing manifests becomes increasingly difficult.

• Filing Amendments - Shipment information often changes after initial submission, requiring updates and amendments.

• Data Accuracy - Incomplete or inaccurate cargo descriptions can create compliance concerns and shipment delays.

• Coordination Across Multiple Offices - Organizations with multiple locations often struggle to maintain consistent filing processes.

• Visibility Into Filing Status - Tracking filing confirmations and shipment activity can become difficult without centralized systems.
