Sources & Methodology
- Base HTS rates: U.S. International Trade Commission — Harmonized Tariff Schedule (2025 edition, Chapter 26). “General rate” shows the min–max range across all 10-digit subheadings.
- Section 301 rates: Office of the U.S. Trade Representative — Section 301 action lists. Flags indicate HTS lines listed on USTR China 301 Lists 1–4B.
- Reciprocal tariffs: Based on the post-SCOTUS Section 122 framework (February 2026). See the TariffCenter Tariff Tracker for current program status.
- Verify before importing: U.S. Customs and Border Protection — Rulings Online or consult a licensed customs broker for binding classification rulings.
Glossary
- General rate (MFN rate)
- The base import duty applied to all World Trade Organization members under Most-Favored-Nation treatment. This is the standard rate shown in the General Rate column.
- Section 301 tariff (301: 7.5%–100%)
- An additional surcharge authorized under Section 301 of the Trade Act of 1974, imposed on selected imports from China. Rates vary by product list and category: Lists 1–3 at 25%, List 4A at 7.5%, with four-year review increases up to 100% on strategic sectors (EVs, semiconductors, solar, medical equipment). Applied on top of the MFN base rate.
- Section 122 surcharge (Sec. 122: 15%)
- A 15% global surcharge on all imports enacted under Section 122 authority after the February 2026 SCOTUS ruling struck down IEEPA-based reciprocal tariffs. USMCA-qualifying goods are exempt. Stacked on top of base and Section 301 rates.
- Section 232 tariff (S232)
- Tariffs on qualifying steel, aluminum, copper, and derivative products imposed under Section 232 of the Trade Expansion Act of 1962 on national security grounds. Rates now vary by product bucket and current Chapter 99 treatment.
- hts_special / Special rates
- Preferential duty rates available to imports from countries with Free Trade Agreements or other special trade programs with the U.S. Country codes: AU (Australia), BH (Bahrain), CA (Canada), CL (Chile), CO (Colombia), IL (Israel), JO (Jordan), KR (South Korea), MA (Morocco), MX (Mexico), OM (Oman), PA (Panama), PE (Peru), SG (Singapore). Free (AU,BH...) means duty-free treatment for those partners.
