Product classification
HS code for Gasoline engine parts: 8409.91
Engines, parts, suitable for use solely or principally with spark-ignition internal combustion piston engines (for other than aircraft).
Classification of gasoline engine parts under HS 8409.91
Gasoline engine parts are classified under HS code 8409.91. This code is situated within Chapter 84, which encompasses nuclear reactors, boilers, machinery, and mechanical appliances. Specifically, heading 8409 is dedicated to parts suitable for use solely or principally with the engines of heading 8407 (spark-ignition internal combustion piston engines) or 8408 (compression-ignition internal combustion piston engines). The subheading 8409.91 is specifically designated for parts of spark-ignition engines, which are typically gasoline-powered, excluding those used for aircraft. Classification under this code requires that the part does not have a more specific heading elsewhere in the Nomenclature. The "solely or principally" rule is critical here; if a part is used for both gasoline and diesel engines, it may fall under 8409.99 unless it is primarily designed for spark-ignition systems.

Codes often confused with 8409.91
Common mistake. A frequent misclassification occurs with HS code 8409.99, which is reserved for parts of compression-ignition (diesel) engines. Importers must verify the ignition type of the engine the part is designed for. Furthermore, many engine components have their own specific headings and should not be classified under 8409.91. For example, spark plugs are classified under 8511.10, gaskets are under 8484, and crankshafts are under 8483.10. General motor vehicle parts that are not engine-specific may also be incorrectly placed here instead of heading 8708.
Top exporters and importers of HS 840991 (the code used for gasoline engine parts), 2025
In 2025, the largest exporter of HS 840991 (the code used for gasoline engine parts) in UN Comtrade data was China, with 18% of world exports; the largest importer in UN Comtrade data was the United States, with 21% 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 840991, not only gasoline 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).

Questions about gasoline engine parts
What is the HS code for Gasoline engine parts?
The HS code for Gasoline engine parts is 840991 (Engines; parts, suitable for use solely or principally with spark-ignition internal combustion piston engines (for other than aircraft)). The HS code for parts used solely or principally with spark-ignition (gasoline) internal combustion piston engines is 8409.91.
How do I classify Gasoline engine parts for customs?
Gasoline engine parts is classified under HS code 840991 — Engines; parts, suitable for use solely or principally with spark-ignition internal combustion piston engines (for other than aircraft). This is a 6-digit subheading level code.
Can I use this code for gasoline engine filters?
No, oil, fuel, and air filters are classified under heading 8421, as they are considered filtering or purifying machinery and apparatus regardless of the engine type.
Which countries are the top exporters of gasoline engine parts (HS 840991)?
