How much is US import duty for "科研、医疗专用" from China?
Using the leading candidate 8539.29.30, the total rate from China is about 32.50% — MFN base plus the Chapter 99 overlays (Section 301 / IEEPA / reciprocal) active for China origin. Other candidates may differ, so verify classification first.
Why is China HS8 not identical to US HTS8?
The WCO Harmonized System is only agreed to six digits. China extends HS6 to 8/10-digit national lines for its own tariffs and statistics, and the US does the same with HTS8/HTS10 — the extensions are independent, so codes must be bridged via HS6.
How do I confirm the final HTS classification?
Compare the US line descriptions against your product facts, check CBP rulings for similar goods, and when in doubt request a binding ruling. The bridge tool lets you re-run this query and compare all candidates side by side.
