The rates in this summary are the full program rates as the calculator computes them; one or more may not apply to your shipment — the conditions are noted below.
Imports from China currently carry a combined tariff of approximately 51.6% — the MFN base rate of 1.6%, the Section 232 (Annex III) measure of 15%, the Section 301 (List 1) rate of 25% (effective July 2018), and a 10% Section 122 emergency surcharge added February 2026, set to expire July 24, 2026. On a $1,000 shipment, that's around $516 in estimated duties. The Court of International Trade struck down Section 122 on May 7, 2026, but CBP is collecting it pending appeal.

Estimates only — not legal or customs advice.
This estimate models the Section 232 measure as a flat 15%. The measure actually applies to the combined duty rate rather than as a separate line — a detail Portigo does not yet compute exactly — so the total shown may be slightly overstated, typically by 0–3%.
The Section 301 rate shown is the full List rate. Active USTR product exclusions may reduce or remove it for specific products — check the USTR exclusion portal and confirm with a licensed customs broker.
