  1. CBP adds error code blocking PSCs on entries with pending CAPE refunds

    CBP announced an updated ACE Entry Summary Error Dictionary. It added error code 864, which blocks a post-summary correction on any entry where a CAPE declaration has already been filed for an IEEPA refund. CBP published this alongside the April 20, 2026 launch of the CAPE tool in the ACE Portal.

    This confirms what CBP had already told filers: once we submit a CAPE declaration for an IEEPA refund, we cannot also file a post-summary correction on that entry. We continue to use CAPE declarations, not PSCs, for IEEPA duty refund requests. Clients do not need to take any action on this notice, but should contact us if they want us to review whether an entry needs a CAPE declaration.

  2. CBP Added ACE Error Code Blocking PSC When a CAPE Refund Is Pending

    CBP announced an updated ACE Entry Summary Error Dictionary that added a new validation error, condition code 864, which blocks a post-summary correction on an entry once a CAPE refund declaration has been filed for it. CBP tied this update to the April 20, 2026 launch of the CAPE tool in the ACE Portal. The change affects filers submitting entry summary corrections.

    Show Allied's position

    We follow this rule when we amend entries for clients that have filed an IEEPA refund claim through CAPE. Once a CAPE declaration is submitted for an entry, CBP will reject any post-summary correction on that entry, so refunds must go through CAPE, not a PSC. This still applies today. Clients do not need to do anything, but should tell us if they want us to check the status of a specific entry.
