HS Code 8407.10 – Engines; for aircraft, spark-ignition reciprocating or rotary internal combustion piston engines
HS code 8407.10 is the 6-digit subheading for engines, for aircraft, spark-ignition reciprocating or rotary internal combustion piston engines. It is used for piston aircraft engines, radial aircraft engines, horizontally opposed aircraft engines, rotary aircraft engines (spark-ignition) and light aircraft engines.
What HS 8407.10 covers
This HS code is dedicated to spark-ignition reciprocating or rotary internal combustion piston engines specifically designed for aircraft. This niche market primarily serves general aviation, light aircraft, and some specialized drone applications, where reliability, weight, and fuel efficiency are critical. The international trade involves highly regulated products, subject to stringent aviation certification standards. Importers are typically aircraft manufacturers, maintenance organizations, and private aircraft owners globally. Exporters are specialized engine manufacturers, predominantly from countries with established aerospace industries. Key aspects include high-performance materials, precision engineering, and extensive testing to ensure airworthiness.

Codes often confused with 8407.10
Common mistake. Distinct from jet/turboprop aircraft engines (8411) which are gas turbines, and from other spark-ignition engines (840721-840790) by their specific 'for aircraft' designation and associated certification.
Top exporters and importers of HS code 840710, 2025
In 2025, the largest exporter of HS code 840710 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).
