Product classification
HS code for Air motor: 8412.39
Engines, pneumatic power engines and motors, other than linear acting (cylinders).
Classification of air motor under HS 8412.39
Pneumatic power engines and motors, commonly referred to as air motors, are classified under HS code 8412.39. This code is situated within Heading 8412, which covers \"Other engines and motors\" that are not elsewhere specified, such as reaction engines, hydraulic power engines, and pneumatic power engines. Subheading 8412.39 specifically addresses pneumatic motors that are not linear acting. While linear acting pneumatic engines (cylinders) are classified under 8412.31, the 8412.39 designation is used for rotary air motors, such as vane or piston types, which convert the energy of compressed air into rotational mechanical motion. These motors are distinct from electric motors (Heading 8501) and internal combustion engines (Heading 8407 or 8408). The classification is determined by the source of power (compressed air) and the nature of the output motion (rotary rather than linear). These motors are widely used in environments where electric sparks must be avoided or where a high power-to-weight ratio is required for industrial tools and machinery.

Codes often confused with 8412.39
Common mistake. The most frequent misclassification occurs with HS code 8412.31, which is strictly for linear acting pneumatic engines (pneumatic cylinders). Another common mistake is classifying an air motor under 8467.11 or 8467.19, which are codes for pneumatic tools. If the motor is imported as a standalone component, it belongs in 8412.39; if it is an integral, non-separable part of a handheld tool, the entire tool is classified under 8467.
Top exporters and importers of HS 841239 (the code used for air motor), 2025
In 2025, the largest exporter of HS 841239 (the code used for air motor) in UN Comtrade data was the United States, with 28% of world exports; the largest importer in UN Comtrade data was the United States, with 15% 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).
