7410.11.00.00 - Of refined copper

This HTS category, 7410.11.00.00, specifically covers copper foil that is not backed by any other material. The foil must be made of refined copper, meaning it has a high purity level, and its thickness, excluding any potential backing (though none is present in this category), should not exceed 0.15 mm. This classification encompasses plain copper foil used in a variety of industrial and manufacturing applications.

It is important to distinguish this category from its sibling, 7410.12.00, which covers similar copper foil but is made from copper alloys. Therefore, the defining characteristic for classification under 7410.11.00.00 is the material composition: exclusively refined copper. The absence of any backing material is also a key criterion, differentiating it from other potential forms of copper sheeting or foil that might be combined with paper, plastics, or similar materials.

As this is a leaf node, there are no further subcategories within 7410.11.00.00. Classification here depends solely on the confirmation of refined copper composition and the absence of any backing material, provided the thickness requirement is met. This ensures precise identification of unadulterated refined copper foil for customs purposes.
