Product classification
HS code for Dirt bike engine: 8407.32
Engines, reciprocating piston engines, of a kind used for the propulsion of vehicles of chapter 87, of a cylinder capacity exceeding 50cc but not exceeding 250cc.
Classification of dirt bike engine under HS 8407.32
Engines for dirt bikes are classified under Chapter 84, which includes nuclear reactors, boilers, and mechanical appliances. Heading 8407 covers spark-ignition reciprocating or rotary internal combustion piston engines. For engines used in the propulsion of vehicles of Chapter 87 (which includes motorcycles and dirt bikes), the classification is further refined by cylinder capacity. Subheading 8407.32 is used for engines with a displacement exceeding 50cc but not exceeding 250cc. This classification applies to the complete engine assembly, which typically includes the cylinder block, head, crankshaft, and pistons. It is important to distinguish the complete engine from individual parts. The engine's intended use in a vehicle and its specific displacement are the primary factors in determining this HS code. According to Section XVI Note 2, parts of machines are generally classified in their respective headings, but a complete engine is a machine in its own right under 8407.

Codes often confused with 8407.32
Common mistake. The most frequent misclassification is using 8409.91, which is for parts suitable for use solely or principally with spark-ignition internal combustion piston engines. If the engine is complete, it must be in 8407. Additionally, engines exceeding 250cc must be moved to 8407.33 (up to 1000cc) or 8407.34 (over 1000cc). Engines for non-vehicle use (e.g., stationary generators) fall under 8407.90.
Top exporters and importers of HS 840732 (the code used for dirt bike engine), 2025
In 2025, the largest exporter of HS 840732 (the code used for dirt bike engine) in UN Comtrade data was China, with 40% of world exports; the largest importer in UN Comtrade data was Mexico, with 34% 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 marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. 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).
