Product classification
HS code for Reciprocating aircraft engines: 8407.10
Engines, for aircraft, spark-ignition reciprocating or rotary internal combustion piston engines.
Classification of reciprocating aircraft engines under HS 8407.10
Reciprocating aircraft engines are classified under HS code 8407.10. This classification is based on the engine's mechanical design and its intended application. Heading 8407 covers spark-ignition reciprocating or rotary internal combustion piston engines. Subheading 8407.10 is specifically dedicated to those engines designed for aircraft. These engines operate on a four-stroke or two-stroke cycle where pistons move back and forth (reciprocate) within cylinders to convert fuel energy into mechanical work. The classification applies regardless of the engine's displacement or power output, provided it is a spark-ignition piston engine intended for aviation. This includes engines for light aircraft, unmanned aerial vehicles (UAVs), and vintage planes. The engine must be presented as a complete unit or an essentially complete unit to qualify under this heading.

Codes often confused with 8407.10
Common mistake. The most common misclassification occurs between reciprocating engines (8407.10) and turbo-jets or turbo-propellers, which are classified under heading 8411. While both power aircraft, 8411 covers gas turbine technology, whereas 8407.10 is strictly for piston-driven technology. Additionally, compression-ignition engines (diesel engines) used in aircraft are classified under heading 8408, specifically 8408.90, as heading 8407 only covers spark-ignition. Parts for these engines are also frequently misclassified; while the engine itself is 8407.10, individual parts are generally classified under 8409.10.
Top exporters and importers of HS 840710 (the code used for reciprocating aircraft engines), 2025
In 2025, the largest exporter of HS 840710 (the code used for reciprocating aircraft engines) in UN Comtrade data was Singapore, with 27% of world exports; the largest importer in UN Comtrade data was Saudi Arabia, with 29% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
