HS Code 848390

HS code 848390 is the World Customs Organization 6-digit HS 2022 subheading for "Transmission shafts (including cam shafts and crank shafts) and cranks; bearing housings and plain shaft bearings; gears and gearing; ball or roller screws; gear boxes and other speed changers, including torque converters; flywheels and pulleys, including pulley blocks; clutches and shaft couplings (including universal joints) : Toothed wheels, chain sprockets and other transmission elements presented separately; parts". The first two digits (84) are the chapter — Nuclear reactors, boilers, machinery and mechanical appliances; parts — and digits 3-4 (8483) are the heading. Countries add further digits (8-10) for their national tariff line.

Common products classified under 848390 include sprocket, toothed wheel, chain sprocket, transmission element, sprocket gear and similar items matching toothed wheels. 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 (848390) 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.
