Frequently asked questions
Which US HTS code corresponds to China HS 3204.1510?
There is no one-to-one mapping: only the first six digits (HS6 320415) are shared internationally. Under this anchor the US schedule has 8 candidate lines; the most common is 3204.15.10.00. Match your product facts (material, use, construction) against the descriptions to pick the right one.
How much is US import duty for "合成靛蓝（还原靛蓝）" from China?
Using the leading candidate 3204.15.10.00, the total rate from China is about 14% — 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.
