Section XVI — Machinery and mechanical appliances; electrical equipment; parts thereof; sound recorders and reproducers, television image and sound recorders and reproducers, and parts and accessories of such articles

About HS Code 840731

This HS code specifically covers small spark-ignition reciprocating piston engines with a cylinder capacity not exceeding 50cc, primarily designed for the propulsion of vehicles classified under Chapter 87. This includes engines for mopeds, scooters, small motorcycles, and some specialized utility vehicles. The international trade in these engines is significant, driven by demand for affordable personal transportation, particularly in developing economies, and for recreational vehicles. Major exporters are often countries with large manufacturing bases for two-wheelers, such as China, India, and Southeast Asian nations. Importers include vehicle assembly plants, parts distributors, and aftermarket suppliers worldwide. Key trade considerations involve engine reliability, fuel efficiency, emissions standards (which are becoming increasingly stringent even for small engines), and cost-effectiveness, as these engines power high-volume, budget-sensitive products.

Products Under This Code

Moped engines, Scooter engines (under 50cc), Small motorcycle engines, Pocket bike engines, ATV engines (small), Go-kart engines (small), Mini-bike engines

Real World Examples

Honda Ruckus engine, Piaggio Zip 50 engine, Yamaha Jog 50 engine, Kymco Agility 50 engine, SYM Fiddle II 50 engine

Common Misclassification

This code is differentiated from 840732 by its strict 50cc cylinder capacity limit, and from 840790 if the engine is not for vehicle propulsion.
