7410.12.00 - Of copper alloys

This HTS category, 7410.12.00, specifically covers copper foil that is not backed and is composed of copper alloys. These alloys are distinct from refined copper, meaning they contain other metals in addition to copper, forming a different material composition. The thickness requirement of not exceeding 0.15 mm (excluding any backing) remains consistent with the broader category for copper foil.

The primary distinction from its sibling category, 7410.11.00.00, lies in the material. While 7410.11.00.00 is reserved for foil made of refined copper, this category is for foil where copper is alloyed with other elements. This difference in composition is a key factor for customs purposes, influencing duties and trade statistics.

Within this category, further subdivisions exist to provide more granular classification. 7410.12.00.30 is designated for foil made from copper-zinc base alloys, commonly known as brass. All other copper alloy foils not falling under the brass classification are directed to 7410.12.00.60. This bifurcation allows for more precise identification of the specific type of copper alloy used in the foil.
