Engines; parts of aircraft engines (spark-ignition reciprocating or rotary internal combustion piston engines)

HS code 840910 covers engines and parts of aircraft engines that utilize spark-ignition reciprocating or rotary internal combustion piston engines. This industry plays a crucial role in the aviation sector, providing the power source for a wide range of aircraft, from small private planes to large commercial airliners. The demand for these engines is closely tied to the growth and development of the global aviation industry, making it an important component of the broader transportation and logistics ecosystem.

The production of engines and engine parts covered under HS code 840910 typically involves a multi-step manufacturing process. This includes the fabrication of engine blocks, crankshafts, pistons, and other key components, often using advanced metalworking techniques such as casting, forging, and machining. Precision engineering is essential to ensure the engines meet strict performance and safety standards required for aircraft applications.

The main inputs for the production of engines and engine parts under HS code 840910 include high-quality metals, such as aluminum, steel, and titanium, as well as specialized lubricants, fuel systems, and electronic control systems. Manufacturers also rely on advanced manufacturing equipment, including CNC machines, welding stations, and testing facilities, to ensure the quality and reliability of the final products.

The primary outputs of the industry covered by HS code 840910 are aircraft engines and their component parts. These engines are then consumed by the 880000 Aircraft, spacecraft, and parts thereof industry, which incorporates them into the final aircraft assembly. Additionally, some engine parts may be used as replacement or maintenance components for existing aircraft, as covered under 848310 (Transmission shafts (including camshafts and crankshafts) 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)).
