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.
Last updated May 7, 2026. Based on CBP Publication 5537-0426 (April 2026).
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.
There is a duty comp code on the entry that CAPE is not able to calculate. Most often because the entry has Extended, Suspended, or Under Review liquidation status. Per CBP, these entries are accepted into CAPE.
Entry summary has a liquidation status of "Pending" or "Not Liquidated" and has a Suspension record.
Entry cannot be in adjusted status. CBP is reviewing it.
Control status for the entry summary must be with CBP. Another agency currently holds control.
A transient system error occurred during processing.
The uploaded CSV needs an "Entry Number" header row and at least one entry number below it.
The uploaded file format must be CSV. Excel workbooks (.xlsx) and other formats are rejected.
The uploaded file cannot be larger than 1 MB.
The system flagged the file content as potentially unsafe.
Each CAPE Declaration upload is limited to 10,000 entry numbers per file.
For Filer and Organizational Broker accounts, the first 3 characters of each entry number must match the Filer Code on the account.
The CSV file contains duplicate entry numbers.
Entry cannot be on a statement that is authorized for payment, but the payment has not yet processed. 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.
Entry must have at least one IEEPA HTS. Either the entry has no IEEPA duties, or IEEPA was embedded in the base rate as FREE instead of a distinct Chapter 99 line.
Importer of Record Number must match the Importer of Record Number of the entry summary. 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.
IEEPA HTS number cannot have a "GDS_VAL_AMT" greater than zero. 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.
Entry summary must exist in ACE.
Entry summary status must be "Accepted."
Entry number must be 11 characters without dashes. Almost always invisible Excel artifacts — cells formatted as Text can carry hidden spaces or leading apostrophes that don't display but count as characters.
Entry summary liquidated/reliquidated more than 80 days ago. Outside CAPE Phase 1 scope.
Entry cannot be on a drawback entry.
TIB (23), Duty Deferral (08), Reconciliation (09), and Drawback (047) entry types are out of scope for CAPE Phase 1.
Entry has been flagged for Reconciliation, which is not allowed in CAPE Phase 1.
Entry summary cannot be flagged for injunction. Resolution is upstream of CBP.
Entry cannot be on an Open or Suspended protest. Entry cannot be in Denied status if AFR box is checked.
The HTS numbers on the line are out of order or unable to calculate due to the HTS being out of the low/high bounds. 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.
