7412.20.00 - Of copper alloys

This HTS category, 7412.20.00, encompasses fittings specifically designed for copper tubes or pipes, where the material of these fittings is composed of copper alloys. These fittings serve a critical function in connecting, diverting, or terminating copper conduits used for fluid or gas transport. Examples include couplings, elbows, tees, reducers, and sleeves that are manufactured from alloys such as brass, bronze, or cupronickel, as opposed to pure refined copper.

The distinction between this category and its sibling, 7412.10.00.00 (Of refined copper), lies solely in the material composition of the fitting. While both fall under the broader heading of copper tube or pipe fittings, 7412.10.00.00 is reserved for fittings made from 99.9% pure copper. Conversely, 7412.20.00 is for fittings where copper is alloyed with other elements, imparting different properties like increased strength, corrosion resistance, or machinability.

Further subdivision within this category recognizes specific applications and general usage. Subcategory 7412.20.00.15 addresses fittings intended for brake hoses in certain types of vehicles, highlighting a specialized use case. The residual "Other" designation covers all other copper alloy tube and pipe fittings not falling under the specialized brake hose provision, ensuring comprehensive classification for the diverse range of products within this material group.
