Calculate your real US import cost in 2026

There is no single China tariff rate. A seller usually needs the MFN base duty for the HTS code, then any China-specific Section 301 duty, current Section 122 status, and product-specific Section 232, AD/CVD, quota, or Chapter 99 layers. Many common China-origin goods require an extra 7.5% to 25% Section 301 check before other remedies.

Treat Section 122 as a separate legal-status item that needs current source review. When it is modeled, TariffsChart keeps it as a separate 10% planning layer instead of merging it into the base HTS duty. Before relying on it, check Federal Register notices, CBP CSMS messages, and current court status.

Section 301 and Section 232 are separate additional-duty authorities, so they can stack on top of the MFN base duty when both apply. Section 301 is often China-origin and list-based, while Section 232 is product-based for categories such as steel, aluminum, autos, and related products. Exclusions, quotas, Chapter 99 instructions, and effective dates can still change the final result.
