HS Code for Air motor

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.

Products Included

• Rotary vane pneumatic motors
• Piston-type air motors
• Pneumatic gear motors
• Air turbines used as primary power sources
• Non-linear pneumatic power units

Common Misclassification

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.

FAQ

What is the HS code for air motor?

The HS code for a rotary (non-linear) pneumatic power engine or air motor is 8412.39.

How do I classify a pneumatic cylinder?

Pneumatic cylinders, which provide linear motion, are classified under HS code 8412.31.
