China HS 7201.2000 (非合金生铁，按重量计含磷量在): US HTS candidates & duty rates

There is no one-to-one mapping: only the first six digits (HS6 720120) are shared internationally. Under this anchor the US schedule has 1 candidate line; the most common is 7201.20.00.00. Match your product facts (material, use, construction) against the descriptions to pick the right one.

Using the leading candidate 7201.20.00.00, 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.

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.

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.
