8481.80.30.65 - Plug type

This classification, HTS Code 8481.80.30.65, specifically covers "Plug type" valves and similar appliances that are hand-operated, made of steel, and fall within the broader category of "Other appliances." These are integral components used for controlling the flow of liquids or gases in various piping systems, boiler shells, tanks, and vats. The "plug type" designation refers to the mechanism by which the valve operates; a tapered or cylindrical plug is rotated within a valve body to open, close, or regulate flow.

Distinguishing this category from its siblings is crucial for accurate classification. While all share the commonality of being hand-operated steel valves, HTS 8481.80.30.65 is distinct from "Gate type," "Globe type," "Ball type," and "Butterfly type" valves based on their specific operating mechanisms. Gate valves use a flat or wedge-shaped gate, globe valves employ a disc that moves against a seat, ball valves utilize a perforated sphere, and butterfly valves use a disc that rotates on a central spindle. This "plug type" category encompasses valves where a plug is the primary sealing and flow-controlling element.

As this is a leaf node, there are no further subcategories for this specific HTS code. Therefore, the focus for classification under 8481.80.30.65 is on verifying that the appliance is indeed a hand-operated valve constructed of steel and that its operational mechanism utilizes a plug design for flow control. Careful examination of the valve's construction and functional principle is necessary to ensure it aligns with the specific definition of a plug type appliance.
