Reminder: Automated Container Seal Change Transmission Now Live in ACE for Ocean and Rail
CBP reminds trade that the automated transmission of container seal changes to ACE manifests for ocean and rail shipments was deployed to the ACE production environment on April 9, 2026. Carriers and NVOCCs must ensure their systems are transmitting seal change data automatically rather than relying on manual updates.
Seal discrepancies are a common exam trigger — clients and their carriers should confirm their manifest software has been updated to transmit seal changes automatically, as manual workarounds are no longer the expected method.
