Import Duty Calculator

An import duty calculator is only as accurate as its inputs. You need the correct 10-digit HTS classification, the country of origin (not country of export), the customs value under the appropriate valuation method, and knowledge of which trade remedy orders cover that heading and origin combination. Get any of those wrong and the calculation is wrong — and CBP's liquidation may differ from your estimate by enough to trigger a CF-28 request for information or a penalty under 19 USC 1592. We provide classification-to-rate lookups, antidumping order coverage by HTS and country, and worked examples for the product categories where importers most often miscalculate their duty exposure.
