8481.80.10.70 - Globe type

This HTS category, 8481.80.10.70, specifically covers "Globe type" valves. These are a type of valve characterized by a disc that moves perpendicularly to the flow path, seating against a circular opening within the valve body to control or stop the flow of fluid. They are designed for applications where precise throttling and tight shut-off are required, often found in plumbing, industrial processes, and steam systems. The defining feature of a globe valve is its internal mechanism, which typically involves a movable plug or disc that seats against a stationary ring seat.

This classification is distinct from its sibling categories based on the operating mechanism and internal design of the valve. For instance, "Gate type" valves (8481.80.10.60) use a wedge-shaped gate that slides up and down to control flow, offering minimal resistance when fully open but less precise throttling. Similarly, "Ball type" valves (8481.80.10.85) utilize a spherical ball with a bore through it to regulate flow, offering quick on/off operation but less suitability for throttling. "Plug type" valves (8481.80.10.75) employ a tapered or cylindrical plug, and "Butterfly type" valves (8481.80.10.90) use a disc that rotates on a central shaft.

As a leaf node within this HTS structure, 8481.80.10.70 does not have further subcategories. Therefore, classification under this code hinges on the definitive characteristic of the valve being of the globe type and meeting the criteria of the preceding headings, specifically being an "Other appliance" under 8481.80, "Hand operated" under 8481.80.10, and constructed "Of copper" with a "pressure rating of 850 kPa or over" under 8481.80.10.70. The focus for correct classification is on the physical and functional attributes that identify the valve as being of the globe design.
