ACE Manifest Modernization Release 2-Rail (INT-061) Scheduled for Production Deployment September 22, 2026
CBP announced that ACE Manifest Modernization Release 2 for Rail (INT-061) is now available in the Certification environment for trade partner testing and is scheduled to deploy to the ACE Production environment on September 22, 2026. Rail carriers, importers, and their brokers who use rail manifests should test against the certification environment promptly.
With a hard production date of September 22, the testing window is short — we advise rail-dependent clients and their carriers to begin certification testing immediately and flag any integration issues to their software vendors well before the cutover.
