HS Code 8412
Hydraulic and Pneumatic Power Engines
HS code 8412 covers other engines and motors, including hydraulic systems, pneumatic power engines, and reaction engines like rocket motors.
HS Code 8412 — Hydraulic and Pneumatic Power Engines
This code covers non-piston and non-turbine engines, such as reaction engines (excluding turbo-jets) and various types of fluid power motors. It is the primary classification for hydraulic and pneumatic (air-powered) cylinders and motors used in robotic arms, conveyor systems, and industrial machinery.
What's included
- Hydraulic cylinders (linear acting)
- Pneumatic reciprocating motors
- Rocket engines (non-jet types)
- Wind engines (windmills)
What's excluded
- Electric motors → use
8501(Electrically powered vs fluid/air powered.) - Hydraulic pumps → use
8413(Pumps provide the flow; 8412 motors receive the flow to create motion.)
Common examples
- Double-acting hydraulic cylinder
- Pneumatic air motor for hand tools
- Solid fuel rocket motor
- Linear hydraulic actuator
Frequently asked questions
Do these include the hoses and valves?
No, hoses (4009) and valves (8481) are classified separately unless they are integral parts of the motor assembly.
Trade & shipping notes
- Typical duty range: 0% - 3%
- Documentation: Specify 'linear acting' or 'rotary' for fluid power units to ensure correct sub-heading.
- Typical shipping mode: LCL
- Top exporters: Germany, United States, China
- Top importers: Canada, Mexico, Japan
