7409.90.10.60 - Other

This HTS classification, 7409.90.10.60, pertains to plates, sheets, and strip of copper alloys, specifically those with a thickness of 5 mm or more. These are formed copper products that do not fall into more specific alloy categories within HTS 7409.90.10. The key defining characteristic for this category is the material composition being an "other" copper alloy, meaning it's not primarily beryllium copper, and the significant thickness of the product.

This category is distinguished from its sibling, 7409.90.10.30, which specifically covers plates, sheets, and strip made of beryllium copper alloys. While both are categorized under "other copper alloys" and share the same thickness requirement (5 mm or more), the presence and concentration of beryllium are the defining factors for classification into the sibling category. This classification, 7409.90.10.60, serves as a residual for other copper alloys that do not meet the specific criteria of beryllium copper.

As this is a leaf node, there are no further subdivisions under this specific HTS code. Therefore, classification under 7409.90.10.60 is final for copper plates, sheets, and strip of a thickness of 5 mm or more that are composed of copper alloys other than beryllium copper. Importers and exporters should ensure they have accurately identified the alloy composition to correctly apply the tariff.
