7408.29 - Other:

This category, HTS Code 7408.29, encompasses copper alloy wires that are not specifically enumerated under the preceding subheadings for copper-zinc base alloys (brass) or copper-nickel/copper-nickel-zinc base alloys. It serves as a residual category for other types of copper alloy wires, meaning it captures a broad range of compositions and applications not otherwise detailed. The key defining characteristic remains that the wire is primarily composed of a copper alloy, but its specific alloying elements fall outside the brass and cupro-nickel classifications.

When classifying a wire under 7408.29, it is crucial to differentiate it from its siblings. HTS 7408.21.00.00 specifically covers wires made of copper-zinc alloys, commonly known as brass. Similarly, HTS 7408.22.00.00 is dedicated to wires of copper-nickel base alloys (cupro-nickel) or copper-nickel-zinc base alloys (nickel silver). Therefore, any copper alloy wire that does not primarily consist of zinc, or a combination including nickel, would be considered for classification within 7408.29.

Within HTS 7408.29, further distinctions are made based on the wire's surface treatment. The subcategories, 7408.29.10.00 and 7408.29.50.00, differentiate between wires that have been coated or plated with another metal and those that have not. This distinction is important for customs purposes as it can affect dutiable value and specific trade regulations. Therefore, when classifying, one must identify if the "other" copper alloy wire has undergone any metallic coating or plating process.
