8481.20.00.10 - Manual type

This HTS classification, 8481.20.00.10, specifically covers manual directional control valves designed for use in oleohydraulic or pneumatic transmissions. These valves are essential components that direct the flow of hydraulic fluid or compressed air within a system, thereby controlling the movement and operation of machinery. The "manual type" designation signifies that their operation is initiated by direct human interaction, such as the movement of a lever, knob, or pedal, rather than by an electrical signal or other automated means.

Distinguishing this category from its siblings, 8481.20.00.20 (Solenoid type) and 8481.20.00.30 (Other), is crucial for accurate classification. While all fall under directional control valves for hydraulic or pneumatic systems, this specific subheading is reserved for those operated manually. Solenoid-type valves, conversely, are activated electronically. The "Other" category would encompass any remaining directional control valves not fitting the manual or solenoid criteria, potentially including pilot-operated or mechanically actuated types if they don't meet the specific parameters of manual operation.

As this is a leaf node within the HTS, there are no further subcategories to introduce. Therefore, classification within 8481.20.00.10 relies heavily on the physical and operational characteristics of the valve. Key considerations for classification include confirming that the valve's primary function is directional control within an oleohydraulic or pneumatic system and that its actuation mechanism is definitively manual. Examples include common lever-operated directional control valves found in excavators, forklifts, and other industrial machinery where direct operator input is required to manage hydraulic functions.
