Use this as a comparison hint, then confirm the final decision with legal notes and country-specific rules.
HS-6 · Subheading
Engines; reciprocating piston engines, of a kind used for the propulsion of vehicles of chapter 87, of a cylinder capacity not exceeding 50cc
Heading 8407 — Reciprocating or rotary internal combustion piston engines
Chapter 84: Nuclear reactors, boilers, machinery
Use HS-6 840731 when importing or exporting small reciprocating piston engines with a cylinder capacity not exceeding 50cc, commonly found in scooters and mopeds. For example, a shipment of 100 small engines intended for electric scooters would fall under this code.
This code specifically covers engines designed for vehicles classified in Chapter 87, which includes motorcycles and bicycles with auxiliary motors. If you're dealing with larger engines, such as those exceeding 50cc, you would need to look at HS-6 840732 instead.
Engines classified under 840731 are typically used in lightweight vehicles and are often packaged individually or in bulk for assembly. If your product is a complete vehicle, you may need to classify it under a different HS code that pertains to the entire vehicle rather than just the engine.
When considering this code, think about the end-use of the engine. If it’s for a lawn mower or other non-vehicle applications, you may need to explore other classifications, such as HS-6 840790 for other internal combustion engines.
