About engines; reciprocating piston engines, of a kind used for the propulsion of vehicles of chapter 87, of a cylinder capacity not exceeding 50cc

hs code 840731 covers reciprocating piston engines with a cylinder capacity not exceeding 50cc, which are used to power various vehicles in chapter 87 of the Harmonized System (HS) classification. These compact engines play a crucial role in the transportation industry, powering a wide range of small vehicles such as mopeds, scooters, and motorcycles. Their importance extends beyond the transportation sector, as they are also utilized in other applications, such as lawn mowers and small power tools.

Production process

The production of engines under hs code 840731 typically involves a multi-step process. First, the engine block is cast or forged, often using aluminum or other lightweight alloys. The crankshaft, pistons, and other internal components are then precisely machined and assembled. The engine is then balanced, tested, and tuned to ensure optimal performance and efficiency. Finally, the engine is integrated into the vehicle's overall design and undergoes further testing and quality control measures before being ready for distribution.

Production inputs

The main inputs required for the production of engines under hs code 840731 include raw materials such as aluminum, steel, and other metals for the engine components. Specialized machinery, such as CNC machines, welding equipment, and testing apparatus, are also essential for the manufacturing process. Additionally, the industry relies on a skilled workforce, including engineers, technicians, and assembly line workers, to ensure the quality and precision of the final product.

Production outputs

The primary output of hs code 840731 is the reciprocating piston engine, which is then incorporated into various small vehicles, such as mopeds, scooters, and motorcycles, classified under 870411 Mopeds, 870421 Motorcycles, with reciprocating internal combustion piston engine of a cylinder capacity not exceeding 50cc, and 870490 Other vehicles, not motorized. These engines may also be used in other applications, such as 842511 Pulley tackle and hoists, powered by electric motor, 842919 Winches and capstans, not powered by electric motor, and 843311 Mowers for lawns, parks or sports-grounds, powered, with the cutting device rotating in a horizontal plane.
