Frequently asked questions

Which US HTS code corresponds to China HS 6901.0000?

There is no one-to-one mapping: only the first six digits (HS6 690100) are shared internationally. Under this anchor the US schedule has 1 candidate line; the most common is 6901.00.00.00. Match your product facts (material, use, construction) against the descriptions to pick the right one.

How much is US import duty for "硅质化石粉（例如各种硅藻土） 或类似硅土制的砖…" from China?

Using the leading candidate 6901.00.00.00, the total rate from China is about 25% — 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.
