ACE Implementation Guides for Entry Type 13 U.S. Mail Test (INT-057 and CBP-290) Elevated to 'Current' Status
CBP has moved the ACE implementation guides for the Entry Type 13 test — covering U.S. mail processing (INT-057) and the Mail Entry Type 13 test (CBP-290) — from draft to current chapter status, signaling that these specifications are now authoritative for system development and filing purposes. Brokers and trade technology vendors building or maintaining mail-entry workflows in ACE should align their systems to the current chapter versions.
We read the elevation of these guides from draft to current as a meaningful compliance signal: our position is that any ACE filing logic or vendor integration touching Type 13 mail entries must now be validated against the current-chapter specifications rather than earlier draft versions.
