ACE Manifest Modernization Release 3-Ocean (INT-062): CERT live, PROD Oct 24

CBP is modernizing ACE ocean, rail, and air manifest systems over several releases. CSMS #69990667 covers Release 3-Ocean (INT-062): a technical migration of back-end ocean manifest functionality. It is in ACE CERT now. PROD deploy is scheduled for October 24, 2026.

INT-062 ocean manifest back-end migration: CERT live for testing; PROD scheduled October 24, 2026. No direct ACE UX or EDI behavior change.

What INT-062 is (and is not)

This is a back-end cutover, not a new ocean manifest data set or a redesign of the ACE screens trade uses day to day. Filers should not expect a change in how ocean EDI looks or behaves at the interface layer. The point of CERT testing is confirming that responses still match what your software expects after the migration.

What trade software developers should do

• Transmit to CERT: CBP says trade software developers may send transmissions to CERT to confirm expected responses before the October 24 PROD window.
• Regression-test ocean paths: Exercise the ocean manifest flows your product actually ships (create, amend, status, query) even though CBP states UX and EDI behavior are not directly changed.
• Log anomalies early: If CERT returns something unexpected, take it to your assigned Client Representative with the COR/transaction identifiers before PROD.
