8481.90.10.00 - Of copper

This classification, 8481.90.10.00, specifically covers parts for hand-operated and check type valves, taps, cocks, and similar appliances, when these parts are made of copper. This includes components used in valves designed for manual operation, as well as those that prevent backflow, such as handles, stems, discs, and housings that are predominantly manufactured from copper alloys.

It is crucial to distinguish this category from its siblings. While 8481.90.30.00 covers similar parts made from iron or steel, and 8481.90.50.00 encompasses parts made from all other materials not otherwise specified, 8481.90.10.00 is exclusively for copper components. The material of construction is the primary differentiating factor at this level.

As this is a leaf node, there are no further subcategories within 8481.90.10.00. Therefore, classification within this code depends solely on the identification of the part as belonging to a hand-operated or check valve assembly and its composition being primarily of copper.
