USTariffCalc is a free, independent tool built to help importers, small business owners, e-commerce sellers, and anyone bringing goods into the United States understand the real cost of importing.
The US tariff system became significantly more complex in 2026. With Section 122 surcharges, Section 301 tariffs on Chinese goods, Section 232 sector-specific duties, and standard MFN rates all stacking on top of each other, calculating the true landed cost of imported goods became a serious challenge — especially for small businesses without a dedicated customs broker.
We built this calculator to make that process simple. Select your country of origin, choose your product category, enter the value, and get a clear breakdown of every duty layer that applies — in seconds.
Our calculator uses publicly available tariff rate data from US Customs and Border Protection, the Office of the United States Trade Representative, and the International Trade Commission. We apply all applicable tariff layers — MFN base duty, Section 122, Section 301, and Section 232 — and include ancillary fees like the Merchandise Processing Fee and Harbor Maintenance Fee.
Rates are updated regularly as trade policy evolves. The current data reflects the post-SCOTUS tariff environment as of April 2026.
This calculator provides estimates for planning purposes only. Actual duties are determined by US Customs and Border Protection based on your product's specific HTS classification, customs valuation, and applicable rulings. Always consult a licensed customs broker for official duty determinations.
