8481.80.10.60 - Gate type

This HTS classification, 8481.80.10.60, specifically identifies gate valves. Gate valves are a type of valve used for controlling fluid flow in pipes, boiler shells, tanks, and similar vessels. Their primary function is to provide a full, unobstructed flow when fully open and a tight shut-off when closed. They are characterized by a sliding gate or wedge that moves perpendicular to the flow path.

Within the broader category of "Other appliances" for pipes, boiler shells, tanks, vats, or the like, which are hand-operated and made of copper and have a pressure rating of 850 kPa or over, this subcategory distinguishes itself from its siblings based on its specific internal mechanism. Unlike globe valves (8481.80.10.70) which use a disc to seat against a valve seat, plug valves (8481.80.10.75) which employ a tapered or cylindrical plug, ball valves (8481.80.10.85) utilizing a spherical closure element, or butterfly valves (8481.80.10.90) which use a disc that rotates on a shaft, gate valves rely on the linear movement of a gate.

As this is a leaf node, there are no further subdivisions under this specific HTS code. Classification under 8481.80.10.60 relies on the definitive presence of the gate mechanism for flow control, alongside the previously established criteria of being a hand-operated copper valve with a pressure rating of 850 kPa or over. If a valve of this type has additional distinguishing features not covered by the "Other" subcategory (8481.80.10.95), it would be classified there.
