CBP ACE Update: Automated Rejections for Incomplete Cargo Manifests

Trade Update • Aug. 26

Key Points

• CBP’s new enhancement auto-rejects cargo filings missing sufficient cargo descriptions, shipper, or consignee names.
• Applied updates span air, ocean, rail, and truck manifest implementation guides.
• Testing is now live in ACE Certification Environment (CERT).
• Official rollout to the ACE Production Environment is scheduled for September 27, 2025.

T

he U.S. Customs and Border Protection (CBP) released a significant enhancement in the Automated Commercial Environment (ACE) Certification Environment (CERT). This update enables automated rejection of manifest and cargo release filings that contain insufficient cargo descriptions, shipper names, or consignee names.

This initiative is part of CBP’s broader ACE modernization efforts to boost automation, compliance, and efficiency across U.S. ports.

Implementation Guide Updates

To support the enhancement, CBP has updated the following implementation guides (with tables of changes in each document):

• Air Import Manifest Appendix A
• Ocean/Rail Import Manifest Appendix D
• ACE Ocean CAMIR Appendix H Common Errors
• Truck Manifest UNEDIFACT CUSRES SN
• ACE Truck Manifest ANSI X12 355 Message
• Standard Manifest Acceptance/Rejection (CUSRES)
• Truck Manifest ANSI X12 350 Message

Why These Updates Matter?

These updates aim to enhance data accuracy and compliance by enforcing stricter validation and automated rejection of manifest filings with insufficient cargo descriptions, shipper names, or consignee names.

For instance, the changes in Air Import Manifest Appendix A include the addition of new error codes such as:

• 548 – Invalid Cargo Description
• 549 – Invalid Shipper Data
• 550 – Invalid Consignee Data

These error codes are designed to trigger automated holds or rejections of manifests when the cargo description or party information is vague, incomplete, or invalid. For example, disposition codes like “6H – Do Not Load – Invalid cargo description, shipper, or consignee hold placed” and “6I – Okay to Load – hold removed” were introduced to specify enforcement actions relating to these data elements.

Impact on Trade and Development

• Trade participants and software developers using the Electronic Data Interface (EDI) must update their systems to comply.
• Immediate testing in the ACE CERT environment is encouraged to ensure readiness.
• Production environment deployment is planned for September 27, 2025, giving time for necessary adjustments.
