How are US import duties from China calculated?

Start with the base MFN rate for the HTS code, then stack the trade-remedy tariffs that apply to China. From China, expect the base duty plus Section 301 (if the code is listed), IEEPA and the reciprocal baseline — and Section 232 on metals. This is the heaviest-stacking origin. The calculator does the stacking for your exact code and value.

Is there a free-trade agreement with China?

No US free-trade agreement applies to this origin, so the base MFN rate plus the reciprocal baseline tariff generally apply.

China import duties

China is the most tariff-exposed origin for US importers. On top of the base MFN rate, goods from China commonly stack the Section 301 List 1–4A duties (7.5–25%, with the 2024 strategic increases reaching 50–100% on EVs, batteries, solar and more), the IEEPA tariff, and the reciprocal baseline. Section 232 applies on steel, aluminum and copper articles regardless of origin.
