7408.22.50.00 - Not coated or plated with metal

This HTS category, 7408.22.50.00, specifically classifies copper wire composed of copper-nickel base alloys (commonly known as cupro-nickel) or copper-nickel-zinc base alloys (also referred to as nickel silver). These wires are characterized by their lack of any metallic coating or plating. The composition is crucial, indicating that the alloying elements, nickel and in some cases zinc, are integral to the copper matrix.

This classification is distinguished from its sibling category, 7408.22.10.00, by the presence or absence of a metallic coating or plating. While both encompass wires made from cupro-nickel or nickel silver alloys, 7408.22.10.00 covers those that have an additional layer of metal applied to their surface, whereas 7408.22.50.00 applies to the bare alloy wire itself.

As this is a leaf node in the HTS classification, there are no further subcategories. Therefore, classification within this specific code relies entirely on meeting the criteria of being a wire of cupro-nickel or nickel silver alloys that is not coated or plated with metal. Examples of such wire could include those used in electrical applications where the alloy's inherent properties, such as corrosion resistance and conductivity, are desired without external surface treatment.
