In a Cargo Systems Messaging Service (CSMS) bulletin published November 21, 2023, U.S. Customs and Border Protection (CBP) announced the migration of the blanket declarations functionality to the modernized ACE Portal from the legacy ACE Portal.
Once the migration is complete, users will not be able to create, manage, and view declarations in the legacy ACE Portal. These functions will only be accessible in the modernized ACE Portal.
The migration of blanket declarations will be completed on December 9, 2023.
