HS Code 840733

HS code 840733 is the World Customs Organization 6-digit HS 2022 subheading for "Sparkignition reciprocating or rotary internal combustion piston engines : Reciprocating piston engines of a kind used for the propulsion of vehicles of Chapter 87 : Of a cylinder capacity exceeding 250 cm³ but not exceeding 1000 cm³". The first two digits (84) are the chapter — Nuclear reactors, boilers, machinery and mechanical appliances; parts — and digits 3-4 (8407) are the heading. Countries add further digits (8-10) for their national tariff line.

Common products classified under 840733 include 500cc engine, 600cc engine, 1000cc engine, motorcycle engine, mid-size engine and similar items matching of a cylinder capacity exceeding 250 cm³ but not…. 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 (840733) 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.
