HS Code for Directional control valve

Directional control valves are essential components in fluid power systems, and their classification is governed by Chapter 84. Heading 8481 covers taps, cocks, valves, and similar appliances for pipes, boiler shells, tanks, vats, or the like, including pressure-reducing valves and thermostatically controlled valves. Subheading 8481.20 is specifically designated for valves used in oleohydraulic or pneumatic transmissions. These valves are used to start, stop, or change the direction of flow of a fluid (liquid or gas) within a power circuit. The classification depends on the valve's application in a fluid power system rather than its material composition. This subheading takes precedence over more general subheadings like 8481.80 when the valve is clearly designed for hydraulic or pneumatic power transmission. The General Interpretative Rules (GRI) require that products be classified according to their function; since these valves control the flow path in a power system, 8481.20 is the most accurate designation.

Products Included

• Hydraulic solenoid directional valves
• Pneumatic spool valves
• Manual lever-operated hydraulic valves
• Monoblock directional control valves
• Sectional hydraulic valves
• Pilot-operated directional valves

Common Misclassification

Directional control valves are frequently misclassified under 8481.80, which is the "other" category for valves like gate, globe, or butterfly valves. The distinction is that 8481.20 is specifically for fluid power (oleohydraulic or pneumatic) systems. They are also sometimes confused with 8412.21 or 8412.31, which are the actual hydraulic or pneumatic cylinders (actuators) that the valves control.

FAQ

What is the HS code for directional control valve?

The HS code for a directional control valve used in hydraulic or pneumatic systems is 8481.20.

Does this code include check valves?

No, check (non-return) valves are specifically classified under HS code 8481.30, even if used in hydraulic systems.
