HS Code 846140

HS code 846140 is the World Customs Organization 6-digit HS 2022 subheading for "Machine tools for planing, shaping, slotting, broaching, gear cutting, gear grinding or gear finishing, sawing, cuttingoff and other machine tools working by removing metal or cermets, not elsewhere specified or included : Gearcutting, geargrinding or gearfinishing machines". The first two digits (84) are the chapter — Nuclear reactors, boilers, machinery and mechanical appliances; parts — and digits 3-4 (8461) are the heading. Countries add further digits (8-10) for their national tariff line.

Common products classified under 846140 include gear cutting machine, gear grinder, gear hobbing machine, gear shaper, gear finishing machine and similar items matching gearcutting. The correct code still depends on the product's material, function and intended use.

Duty is set by the destination country, not by the 6-digit HS code alone. Start from the official tariff of your market — USITC HTS (US), TARIC / Access2Markets (EU), GOV.UK Trade Tariff (UK), CBSA (Canada), ABF (Australia) or Singapore Customs — and look up the full national code with China as the country of origin.

The first 6 digits (846140) are the same worldwide under the WCO Harmonized System. Beyond that, each country extends the code (HTS in the US, TARIC in the EU, etc.) and sets its own duty and tax rates.

Treat a supplier-provided code as a clue, not a final classification. It can be incomplete, China-export-specific, or mismatched to your destination's rules. Verify against the official tariff and your product's actual material and use.
