7412.10.00.00 - Of refined copper

This HTS category, 7412.10.00.00, specifically classifies fittings designed for copper tubes or pipes that are exclusively made from refined copper. These fittings serve crucial roles in plumbing, industrial piping systems, and other applications where the joining, directing, or terminating of refined copper conduits is necessary. Examples include couplings for joining two pipes, elbows for changing direction, tees for branching, and reducers for connecting pipes of different diameters, all manufactured from pure copper.

It is important to distinguish this category from its sibling, 7412.20.00, which covers fittings made of copper alloys. While both categories address copper tube or pipe fittings, the material composition is the defining factor for classification. Fittings classified under 7412.10.00 must be composed of refined copper, meaning they contain a very high percentage of copper with minimal or trace amounts of other elements. Fittings made from alloys, such as brass or bronze, which inherently contain significant additions of other metals like zinc or tin, would fall under the 7412.20.00 classification.

As this classification is a leaf node, there are no further subcategories. Therefore, the primary focus for classification under 7412.10.00.00 is the confirmed material composition of the fitting. Importers and exporters should ensure that their documentation accurately reflects that the fittings are indeed constructed solely from refined copper to ensure correct entry and compliance with customs regulations.
