Tariff Refund Calculator: IEEPA, Section 301/232 and Drawback Duty Recovery Estimator

Stop guessing what your tariff overpayment is worth.

A single-file browser tool that turns an entry list into a recoverable-duty estimate with the filing clock counted for you. Six refund bases (IEEPA, Section 301 exclusions, Section 232, misclassification, valuation corrections, drawback), each with the right recovery rate and statutory window already wired in.

What you get

• The calculator: one HTML file, works offline in any browser
• CSV import and export, so 400 entries take a minute
• A print-ready claim summary for a client or CFO
• A per-entry claim worksheet CSV for your broker
• Plain-English guide and a commercial license (unlimited client work)

Why it is different

Most duty calculators multiply value by rate and stop. This one counts the deadline: it separates eligible duty from duty paid, computes statutory interest by entry age, flags every line inside 45 days of its protest window, and prices your contingency fee so you can quote on the spot.

Who buys this

Customs brokers, trade consultants, importers and finance teams who need a defensible number by Friday.
