8481.80.10 - Of copper

This HTS subheading, 8481.80.10, specifically classifies taps, cocks, valves, and similar appliances when they are made *of copper* and fall under the broader category of "Other appliances" within hand-operated devices. This category encompasses a wide array of valves and fittings used for controlling the flow of liquids or gases in various systems, including those found in pipes, boilers, tanks, and vats.

It is crucial to distinguish this category from its siblings. While 8481.80.30 covers similar appliances made *of iron or steel*, and 8481.80.50 includes those made *of other materials*, this subheading is exclusively for copper-based products. The material of construction is the primary determining factor for classification at this level, ensuring accurate tariff application based on the component metal.

The subcategories within 8481.80.10 further refine the classification based on the pressure rating of the valve. Appliances are divided into those with a pressure rating *under 850 kPa* and those with a pressure rating *of 850 kPa or over*. This distinction is important for customs purposes as it can relate to the intended application and performance specifications of the copper valve or appliance.
