ACE Highway Update: COO Validation for Section 321

ACE Highway Update: COO Validation for Section 321

Please be advised that a new validation rule has been deployed in ACE Highway. In alignment with the latest CBP compliance requirements, the system now restricts the selection of Country of Origin (COO) = China (CN) for Section 321 shipments. Users will no longer be able to submit Section 321 entries with COO set to CN.
