7410.22.00.00 - Of copper alloys

This HTS category, 7410.22.00.00, specifically classifies copper foil that is backed with materials such as paper, paperboard, plastics, or similar backing substances. The critical defining characteristic of this foil is its thickness, which must not exceed 0.15 mm, excluding the thickness of any backing material. This classification applies regardless of whether the foil is printed or decorated.

It's important to distinguish this category from its sibling, 7410.21, which covers unbacked copper foil meeting the same thickness and material specifications. While both deal with thin copper foil, the presence of a backing material is the sole determinant for classification under 7410.22.

As this is a leaf node in the HTS structure, there are no further subcategories. Therefore, the classification is definitively determined by the presence of a backing material and the specified thickness, encompassing a range of applications where copper foil is integrated with other substrates for enhanced functionality or handling.
