The CAPE route
CAPE — Consolidated Administration and Processing of Entries — is the administrative path CBP built for this refund specifically. Filers upload a CSV of entry numbers through the CAPE tab in their ACE Portal Importer, Organizational Broker or Filer sub-account.
CBP validates the file before anything else happens: that the submitter is the importer of record for the listed entries or the broker who filed those entry summaries, that entry numbers are present, and that the format is correct. A declaration that fails validation is rejected as a whole.
An accepted CAPE declaration cannot be withdrawn or amended. That is the single most consequential property of this route, and it is why reconciliation against the original 7501 before filing matters more here than in ordinary customs work.
CBP has indicated valid refunds are generally issued within 60–90 days of a declaration being accepted, which includes roughly 45 days of CBP review plus Treasury processing time.
The protest route
A protest under 19 U.S.C. § 1514 is the older, general-purpose mechanism for contesting a CBP decision. It is filed on CBP Form 19, through the ACE Protest Module or on paper, by the importer, their broker, or their attorney.
Two constraints define it. A protest can only be filed after an entry liquidates — it contests a final determination, so there must be a determination to contest. And it must be filed within 180 days of the notice of liquidation; missing that window permanently bars the administrative challenge for that entry.
Because liquidation happens per entry, the deadline is per entry too. Two entries liquidated a week apart have deadlines a week apart. Our free deadline calculator computes the date from a liquidation date; whether a protest is the right route for a given entry is a determination for a licensed customs broker or attorney.
What stops a refund that was otherwise fine
Refunds stall for reasons unrelated to eligibility, and these account for a large share of what is still outstanding:
No banking details on file. Refunds do not process without ACH enrolment on the ACE Portal account. An accepted declaration with no account to pay into simply sits.
Offsets. Under 19 CFR 24.72(b), a refund can be applied against other debts owed to CBP before anything reaches the importer.
Line-level mismatches. CBP has been rejecting a substantial share of CAPE declarations on mismatches against the original 7501 — HTS code, value or quantity at the line level. One bad line rejects the whole declaration.
The contested tail. The government's appeal argues that refunds on finally-liquidated entries belong only to the importers who sued. That question is unresolved, and deadlines keep running while it is.
