Questions people ask before they trust a number
- What is the US import duty on 8517.13.00.00 from China?
- Stacked by the rule engine, the total ad valorem rate is about 20.0%. Made up of: MFN base rate (Col. 1 General) 0.0%, Section 301 · List 4A (China origin — list scope approximated by chapter, official list prevails) 7.5%, Section 301 · Forced labour 12.5% (Annex II exclusions not yet parsed) 12.5%. Every component carries its official source and effective date.
- What other US federal fees apply?
- The US charges a Merchandise Processing Fee of 0.3464% (min $32.71, max $634.62) and a Harbor Maintenance Fee of 0.125% (ocean freight only). Try a value in the landed-cost calculator.
- Does this include Section 301, Section 232 and the forced-labour surcharge?
- Yes. The US stack is MFN base + Section 301 (China lists and the 2024 four-year-review code-level rates) + the Section 301 forced-labour surcharge (10% or 12.5% across 60 economies, 12.5% for China, from 2026-07-24; goods subject to Section 232 are exempt) + Section 232 (steel/aluminium/copper 50%, autos 25%, wood 10–50%, with UK/EU/JP/KR/TW exceptions). Section 122's global 10% expired on 2026-07-24 and the engine stops stacking it by query date. The IEEPA country-by-country reciprocal tariffs were struck down by the Supreme Court on 2026-02-20.
- Is Section 232 definitely applicable to this code?
- We match Section 232 at chapter level (steel Ch.73, aluminium Ch.76, copper semi-finished, autos 8703/8708, wood Ch.44 and 9401/9403). Actual applicability and the derivative-product lists are determined by the controlling proclamation and BIS guidance.
- Where does this data come from?
- Codes and MFN base rates come from the full USITC HTS HTS-2026-Rev.11 export. Section 301/232 product scope is an approximation of each Annex. Every rate carries source_url and effective_from, so you can trace it back to the controlling notice.
