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.
