HS Code for Hydraulic motor

Hydraulic motors are classified under HS code 841229 because they are defined as hydraulic power engines and motors that are not linear acting. In the Harmonized System, heading 8412 encompasses various engines and motors, with the 8412.2x subseries specifically dedicated to hydraulic power systems. While 841221 is reserved for linear acting systems such as hydraulic cylinders, 841229 serves as the residual category for rotary hydraulic motors. These devices convert hydraulic energy into mechanical rotation. The classification is determined by the motor's primary function of providing rotational force through the movement of pressurized fluid, typically oil. This code applies regardless of the internal design—whether gear, vane, or piston-based—as long as the output is rotary rather than linear. Proper classification requires distinguishing these motors from hydraulic pumps, which add energy to the fluid, whereas motors extract energy from the fluid to perform work.

Products Included

• Axial piston hydraulic motors
• Radial piston hydraulic motors
• Hydraulic gear motors
• Vane-type hydraulic motors
• Gerotor and orbit motors
• High-torque low-speed (HTLS) hydraulic motors

Common Misclassification

A frequent error involves confusing hydraulic motors with hydraulic pumps classified under heading 8413. While they may look identical externally, their function is opposite. Additionally, hydraulic cylinders are often misclassified here but belong under 841221 because they are linear acting. Electric motors used to drive hydraulic systems are also excluded and should be classified under heading 8501.

FAQ

What is the HS code for hydraulic motor?

The primary HS code for rotary hydraulic motors is 841229. Linear hydraulic motors (cylinders) are classified under 841221.

How do I distinguish a hydraulic motor from a pump for customs?

Classification depends on the direction of energy transfer. If the device uses fluid pressure to create mechanical rotation, it is a motor (841229). If it uses mechanical rotation to move fluid, it is a pump (8413).
