7606.12 - Of aluminum alloys:

This HTS category, 7606.12, encompasses rectangular (including square) plates, sheets, and strip made from aluminum alloys, with a thickness exceeding 0.2 mm. These products are characterized by their metallic composition of aluminum with added elements that enhance properties such as strength, corrosion resistance, or workability, distinguishing them from pure aluminum.

The primary distinction of this subcategory lies in its material composition. Sibling category 7606.11 specifically covers similar forms of aluminum that are *not* alloyed, meaning they consist predominantly of pure aluminum. Therefore, the presence of alloying elements is the key differentiator when classifying goods under 7606.12.

Further classification within this category is determined by whether the product is clad. Subcategory 7606.12.30 applies to plates, sheets, and strip of aluminum alloys that are not clad, meaning they are of a uniform alloy composition throughout their thickness. In contrast, 7606.12.60.00 covers clad products, where one or more layers of a different material (often aluminum or another metal) are bonded to the surface of the aluminum alloy base. This cladding can be for aesthetic, protective, or functional purposes.
