7409.90.90.60 - Other

This HTS classification covers copper plates, sheets, and strip, exceeding 0.15 mm in thickness, and made from copper alloys other than those specifically enumerated elsewhere. These products are further refined by a thickness of less than 5 mm and a width of less than 500 mm. The "Other" designation signifies that these are alloys of copper that do not fall into more specific compositional categories within this level of the tariff schedule. Examples could include certain brasses, bronzes, or nickel-silvers if they meet the dimensional criteria and are not classified under more precise alloy-based subheadings.

Crucially, this category is distinguished from its sibling, HTS 7409.90.90.30, which specifically covers articles made of beryllium copper. While both are "other copper alloys" and share the same dimensional restrictions, the presence of beryllium in the sibling category dictates its separate classification. This highlights the importance of precise material composition in determining the correct HTS classification, even for ostensibly similar products.

As a leaf node, this classification does not have further subdivisions. Therefore, classification into this subheading hinges entirely on the material composition (an alloy not otherwise specified), the thickness exceeding 0.15 mm, the thickness being less than 5 mm, and the width being less than 500 mm. Importers and exporters must meticulously verify these physical and compositional attributes to ensure accurate declaration.
