HS Code for Rotary hydraulic motor

Rotary hydraulic motors are classified under HS code 8412.29. This classification is based on the mechanical function and power source of the device. Heading 8412 covers "Other engines and motors," including hydraulic, pneumatic, and other non-electric power units. Within this heading, the 8412.2x series is dedicated specifically to hydraulic power engines and motors. The distinction between subheadings is based on the type of motion produced. Subheading 8412.21 is reserved for linear acting motors, such as hydraulic cylinders. Consequently, any hydraulic motor that produces rotational motion (torque) rather than linear force is classified under the residual subheading 8412.29. This includes various designs such as gear, vane, and piston motors that convert fluid pressure into continuous rotary movement.

Products Included

• Hydraulic gear motors
• Hydraulic vane motors
• Radial piston hydraulic motors
• Axial piston hydraulic motors
• Hydraulic orbital motors

Common Misclassification

The most frequent misclassification occurs with HS code 8413.60, which covers rotary positive displacement pumps. While pumps and motors may look identical and share internal components, their function is opposite: a pump converts mechanical energy into hydraulic flow, while a motor converts hydraulic flow into mechanical torque. Another common error is using 8412.21. This code is strictly for linear actuators (cylinders). If the device rotates a shaft, it must be 8412.29. Additionally, electric motors used in hydraulic systems must be classified in heading 8501, not 8412.

FAQ

What is the HS code for Rotary hydraulic motor?

The HS code for a rotary hydraulic motor is 8412.29, which encompasses hydraulic power engines and motors that are not linear acting.

Can a hydraulic pump be classified under this code?

No, hydraulic pumps are classified under heading 8413. Even if a unit is capable of acting as both a pump and a motor, it is typically classified based on its primary intended use or as a pump if the functions are equal, per GRI 3(c).
