Find your error. Know what it means. See exactly what to do next. If a claim number exists in the Claims tab, your Declaration was received regardless of any error message.
The backend queue was overloaded and your Declaration never entered processing. Nothing was lost.
System is under load. Self-resolving.
Your Declaration is queued but CBP's batch processor hasn't picked it up. Can persist 24 to 48 hours under peak load.
UI timeout only. The browser stopped waiting before the server finished. If a claim number appears in the Claims tab, the Declaration was accepted.
A line failed validation, most often because the entry has Extended, Suspended, or Under Review liquidation status. Per CBP, these entries are accepted into CAPE.
Liquidation status is Pending or Not Liquidated and a Suspension record exists.
Entry is in adjusted status. CBP is reviewing it.
Control status must be with CBP for CAPE to act. Another agency currently holds control.
The periodic statement covering this entry hasn't closed in ACE. Common with March or April 2026 entries or entries with a pending PSC.
These are Section 122 surcharges (10% tariff effective February 24, 2026), separate from IEEPA and not refundable through CAPE.
CBP doesn't see a 9903.01.xx or 9903.02.xx subheading. Either the entry has no IEEPA duties, or IEEPA was embedded in the base rate as FREE instead of a distinct Chapter 99 line.
The entry number doesn't exist in ACE or isn't associated with the IOR submitting the Declaration. Three common causes: UPS/FedEx is the actual IOR, a DBA is registered differently in ACE, or only the filing broker can submit CAPE for it.
Entered value belongs on the Chapter 1 to 97 commodity line, not the Chapter 99 IEEPA line. The entry was rejected (not accepted), so PSC is still available.
The entry number doesn't exist in ACE under your account.
The entry summary status must be Accepted for CAPE processing.
Almost always invisible Excel artifacts. Cells formatted as Text can carry hidden spaces or leading apostrophes that don't display but count as characters.
Liquidated or reliquidated more than 80 days ago. Outside CAPE Phase 1 scope.
An active drawback claim conflicts with CAPE processing.
TIB (23), Duty Deferral (08), Reconciliation (09), and Drawback (047) entry types are out of scope for CAPE Phase 1.
The reconciliation flag blocks CAPE Phase 1 processing.
A legal hold prevents CAPE processing. Resolution is upstream of CBP.
An Open or Suspended protest blocks CAPE. Also blocks if Denied with AFR box checked.
CBP validation flags an inconsistency between the Chapter 99 code and the underlying commodity code. Predominantly hitting FTZ weekly entries (Type 06 withdrawals).
CAPE accepts 9903.01.26 (IEEPA-RECIPROCAL EXCLUSION CA) with $0.00 duties, but rejects 9903.01.28 (IEEPA-RECIPROCAL EXCL IN TRAN) and 9903.01.23 (CHINA/HONG KONG EXCLU 0% DUTY).
Once a CAPE Declaration is accepted on an entry, all PSC filings on that entry are blocked until liquidation. The block is entry-wide, not just IEEPA lines.
ACE account deactivated for inactivity. Inactivity windows have shortened significantly under CAPE load.
Different from Error 42. Requires CBP manual reactivation, not just a Support unlock.
CBP confirmed Chapter 73 articles with no steel are not intended to be subject to Section 232, but the only HTS exclusion (9903.82.03) covers Chapters 72, 73, 74, and 76 generally, with no operational mechanism to exclude no-metal-content goods at entry.
