This message is from April 19, 2026. Later CSMS messages may have changed it. See the latest trade news
What did CBP announce?
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.
What is 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.
General information, not legal advice.
