Tariff refund calculatorCSV upload

Estimate tariff refund exposure from the customs CSV you have.

Upload a broker export, ACE ES-003-style report, or entry-level customs CSV. The calculator totals supportable IEEPA refund exposure, shows weak fields, and opens a dedicated review workspace with the next prep step.

Source files

The calculator is built for operational customs exports.

Use the file closest to the source of truth. Rich analysis files can include tariff lines, amounts, liquidation clues, and broker references; downstream CAPE-oriented files should stay focused on clean entry numbers.

File typeBest useWhat to check
ACE ES-003-style exportBest source for line-level tariff detail and entry-number review.Entry numbers, importer, Chapter 99 signals, amounts, liquidation and status fields.
Broker entry exportFastest path when the broker already isolated IEEPA duty amounts.Entry-level rows, IEEPA amount, importer name, date, port, broker, and source references.
Messy internal CSVUseful for triage when finance has partial customs data.Enough columns to map entries, importers, dates, and visible duty amounts.

Clean entry-number list before CAPE-oriented preparation.

Importer rollups for prioritizing the largest exposure first.

Liquidation, warehouse, protest, drawback, and status blockers.

Payee, 4811 party, actual-owner, and notify-party documentation prompts.

ACE access and ACH refund readiness prompts.

Paid Declaration Pack Builder path when the file is ready.

Claim-prep bridge

Use the estimate to decide what deserves paid preparation.

The free estimate should narrow the work. Paid Declaration Pack Builder support is for files ready for validation, canonical exports, payee notes, and broker or counsel handoff.

FAQ

Questions before you upload.

What does the tariff refund calculator estimate?
It estimates likely refundable IEEPA duty exposure from the amount fields in a broker export, ACE report, or entry-level customs CSV. It also shows where the source file is incomplete.
Is an ACE ES-003 export different from a CAPE Declaration CSV?
Yes. An ACE ES-003-style export can include rich tariff-line detail for analysis. A CAPE Declaration CSV is a downstream entry-number file used in ACE. This calculator helps prepare and validate data before that handoff.
Does this page file a refund claim with CBP?
No. This is estimate and preparation software only. It does not file with CBP, provide legal advice, or act as a customs broker.
When should I move from a free estimate to paid pack prep?
Move forward when the file has usable entry numbers, importer data, IEEPA amounts, and enough status detail to support validation, export, and broker or counsel review.
