8481.80.30.10 - Gate type

This category specifically covers hand-operated gate valves made of iron. Gate valves are characterized by a sliding gate or wedge that moves perpendicular to the flow path to control or stop the flow of a fluid. The "gate type" distinction is crucial, differentiating them from other valve mechanisms. These are distinct from other valve types at this level, such as globe, plug, ball, or butterfly valves, each employing a different method for flow regulation.

The classification here is narrowed down to hand-operated iron gate valves. This means the valve is designed to be opened and closed manually, typically via a handwheel or lever. The material being specifically iron is a key determinant, differentiating these from valves constructed from other metals or materials.

As this is a leaf node in the HTS structure, there are no further subcategories. Therefore, the focus remains on clearly identifying hand-operated gate valves made of iron. Importers and exporters should ensure the physical characteristics and operational mechanism of the valve precisely match this description to ensure correct classification.
