Frequently asked

What is the United States import duty on 3812.39.30.00 from China?

What other United States 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 origin, the single list / 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 baseline 50%, with a UK 25% and a Russia aluminium 200% exception) — fully stacked, which is exactly where most free tools get it wrong. Section 122's global 10% surcharge statutorily expired on 2026-07-24, and the engine stops stacking it automatically based on the query date; the IEEPA country-by-country reciprocal tariffs were struck down by the Supreme Court on 2026-02-20.
Where does this data come from?
Codes and MFN base rates come from the full USITC HTS 2026 Rev.11 export. Section 301/232/122 surcharge mappings are approximated pending code-level review. Every rate carries a source_url and effective_from, so you can trace it back to the controlling notice.
