HS v2022 Code: 840710

About engines; for aircraft, spark-ignition reciprocating or rotary internal combustion piston engines

HS code 840710 covers aircraft engines that utilize spark-ignition reciprocating or rotary internal combustion piston technology. This industry plays a critical role in the global aviation sector, providing the power source for a wide range of aircraft, from small private planes to large commercial airliners. The demand for these specialized engines is driven by the continued growth and modernization of the aviation industry, as well as the need for reliable and efficient power plants to meet increasingly stringent environmental regulations.

Production process

The production of aircraft engines under HS code 840710 involves a complex and highly specialized manufacturing process. Key steps include the precision machining of engine components, such as cylinder blocks, crankshafts, and pistons, as well as the assembly and testing of complete engine units. Advanced computer-aided design (CAD) and computer numerical control (CNC) technologies are often employed to ensure the tight tolerances and high-quality standards required for these critical aviation components.

Production inputs

The manufacture of HS code 840710 engines requires a range of specialized inputs, including high-performance metals and alloys, such as aluminum, titanium, and nickel-based superalloys, as well as advanced lubricants and fuel systems. Additionally, these engines rely on specialized production equipment, including CNC machine tools, precision measurement instruments, and advanced testing and quality control systems. The industry also requires a highly skilled workforce, with expertise in areas such as aerodynamics, thermodynamics, and materials science.

Production outputs

HS code 840710 engines are the primary power source for a wide range of aircraft, including 880240 Aeroplanes and other aircraft, of an unladen weight exceeding 15,000 kg, 880230 Aeroplanes and other aircraft, of an unladen weight exceeding 2,000 kg but not exceeding 15,000 kg, and 880240 Aeroplanes and other aircraft, of an unladen weight not exceeding 2,000 kg. These engines are also used in some specialized ground-based applications, such as auxiliary power units (APUs) for aircraft and other industrial equipment.
