Product classification
HS code for Aircraft engine parts: 8409.10
Engines, parts of aircraft engines (spark-ignition reciprocating or rotary internal combustion piston engines).
Classification of aircraft engine parts under HS 8409.10
Aircraft engine parts, specifically those for spark-ignition reciprocating or rotary internal combustion piston engines, are classified under HS code 840910. Chapter 84 of the Harmonized System encompasses nuclear reactors, boilers, machinery and mechanical appliances, and parts thereof. Heading 8409 is dedicated to "Parts suitable for use solely or principally with the engines of heading 8407 or 8408." Heading 8407 covers spark-ignition reciprocating or rotary internal combustion piston engines. The subheading 10 then specifically narrows this down to parts suitable for use solely or principally with "aircraft engines." This precise classification ensures that components integral to these specific types of aircraft powerplants are correctly identified.

Codes often confused with 8409.10
Common mistake. Aircraft engine parts can be misclassified if the specific engine type or application is not carefully considered. A common error is to classify them under more general engine parts codes, such as HS code 840991 for parts of spark-ignition engines for vehicles of Chapter 87 (automotive), or 840999 for other parts of engines of 8407 or 8408. However, 840910 is specifically for aircraft engines and takes precedence. Another potential misclassification is under HS code 8803, which covers "parts of aircraft." While engine parts are indeed for aircraft, their mechanical nature and specific function within the engine lead to their classification under Chapter 84, which is more specific for machinery components.
Top exporters and importers of HS 840910 (the code used for aircraft engine parts), 2025
In 2025, the largest exporter of HS 840910 (the code used for aircraft engine parts) in UN Comtrade data was Saudi Arabia, with 60% of world exports; the largest importer in UN Comtrade data was Saudi Arabia, with 58% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.
Figures cover everything classified under HS 840910, not only aircraft engine parts.

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).
