7606.11 - Of aluminum, not alloyed:

This HTS category, 7606.11, encompasses plates, sheets, and strip of aluminum that exceed 0.2 mm in thickness and are rectangular in shape. Critically, this classification applies specifically to aluminum that is not alloyed, meaning it is pure aluminum or contains only trace amounts of other elements, not enough to significantly alter its properties or warrant classification as an alloy. These are typically flat, rolled aluminum products used in a wide variety of industrial and manufacturing applications.

It is important to distinguish this category from its sibling, 7606.12, which covers similar rectangular plates, sheets, and strip of aluminum, but exclusively those that are alloyed. The presence or absence of alloying elements is the primary differentiating factor for classification at this level, influencing the material's properties, such as strength, hardness, and corrosion resistance.

The subcategories within 7606.11 further refine the classification based on whether the aluminum product is clad or not clad. 7606.11.30 applies to non-clad products, which consist solely of the unalloyed aluminum material. In contrast, 7606.11.60.00 covers clad products, where a layer or layers of other materials, typically other aluminum alloys or non-aluminum metals, have been bonded to the unalloyed aluminum core.
