8481.80.10.85 - Ball type

This HTS classification covers ball valves that are designed for piping systems, boiler shells, tanks, vats, and similar applications. These valves are characterized by a spherical closure element with a bore through the center, which rotates to control flow. Specifically, this subcategory includes ball type valves that are hand-operated, made of copper, and have a pressure rating of 850 kPa or over. Their primary function is to regulate or stop the passage of fluids or gases.

It is important to distinguish this classification from its siblings. While all fall under the broader category of "Other appliances: Hand operated: Of copper: Having a pressure rating of 850 kPa or over," this specific code is reserved for valves employing a ball mechanism. Sibling categories like "Gate type" (8481.80.10.60) utilize a sliding gate, "Globe type" (8481.80.10.70) use a plug that moves along a seat, and "Plug type" (8481.80.10.75) employ a tapered or cylindrical plug for flow control. The "Butterfly type" (8481.80.10.90) uses a disc that rotates on a central shaft.

As a leaf node, 8481.80.10.85 represents the most granular classification for this specific type of valve. Therefore, the focus for classification here is on confirming the presence of a ball mechanism as the primary closure element, the hand-operated nature, the material of construction (copper), and the specified minimum pressure rating. Further subdivisions are not applicable at this level, meaning that any hand-operated, copper ball valve meeting the pressure requirement falls under this code.
