Product classification
HS code for Aviation engine parts: 8409.10
Engines, parts of aircraft engines (spark-ignition reciprocating or rotary internal combustion piston engines).
Classification of aviation engine parts under HS 8409.10
Aviation engine parts for spark-ignition reciprocating or rotary internal combustion piston engines are classified under HS code 8409.10. Chapter 84 includes machinery and mechanical appliances. Heading 8409 is specifically designated for parts suitable for use solely or principally with the engines of heading 8407 (spark-ignition) or 8408 (compression-ignition). Subheading 8409.10 is the specific carve-out for aircraft engines. This classification is crucial because it distinguishes engine components from general aircraft parts found in Chapter 88. To fall under this code, the part must be identifiable as being for a piston-driven aviation engine, such as a cylinder head or a piston ring, rather than a part for a turbo-jet or other propulsion system. The classification follows GRI 1 and Note 2 to Section XVI, which states that parts of machines are to be classified according to specific rules, often leading them to heading 8409 for internal combustion engines.

Codes often confused with 8409.10
Common mistake. The most frequent misclassification is HS code 8803 (now 8807 in newer versions), which covers parts of aircraft. Importers often assume all aircraft-related items belong in Chapter 88. However, Note 2(e) to Section XVII excludes machines and apparatus of headings 8401 to 8479 and parts thereof. Therefore, engine parts must stay in Chapter 84. Another error is using 8411.91 or 8411.99, which are for parts of turbo-jets or gas turbines; these are distinct from the piston engines covered by 8409.10.
Top exporters and importers of HS 840910 (the code used for aviation engine parts), 2025
In 2025, the largest exporter of HS 840910 (the code used for aviation 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.

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).
