HS Code for Hydraulic valve

Hydraulic valves are classified under HS code 848120, which specifically covers valves for oleohydraulic or pneumatic transmissions. Heading 8481 is the general category for taps, cocks, valves, and similar appliances for pipes, boiler shells, tanks, and vats. However, the 848120 subheading is a functional classification that takes precedence over the general 'other' categories (like 848180) when the valve is designed for fluid power systems. 'Oleohydraulic' refers to the use of liquid (usually oil) under pressure to transmit energy. These valves are engineered to handle high pressures and provide precise control over fluid direction, pressure levels, and flow rates. Because they are integral to the 'transmission' of power rather than just the simple transport of fluid, they are grouped with pneumatic valves in this specialized category. This classification applies regardless of whether the valve is manually, mechanically, or solenoid-operated.

Common Misclassification

The most common error is using the general valve code 848180. If the valve is part of a hydraulic power circuit, 848120 is more specific and legally required. Another error involves classifying valves with actuators as 'parts of machines' under 841290; however, Note 2 to Section XVI specifies that valves of heading 8481 must be classified there even if designed for a specific machine.

FAQ

What is the HS code for hydraulic valve?
