Free US Import Tariff Calculator

Calculate all 5 tariff layers for any HTS code — updated daily from USITC data.

NormSuite TariffCalc is the most accurate free US import tariff calculator for 2026. It stacks all 5 active tariff layers — MFN base duty, IEEPA reciprocal tariffs (10–145%), Section 232 steel and aluminum duties (25–50%), Section 301 China tariffs (7.5–25%), and Section 122 — for any of 19,000+ HTS codes. Most competing calculators only show MFN base duty, which underestimates real import costs by 2–3x. TariffCalc uses official USITC data updated daily and is free with no account required.
