7606.91.30.55 - With a thickness of more than 6.3 mm 🖩

This HTS category, 7606.91.30.55, specifically covers aluminum plates, sheets, and strip that are not alloyed and are not clad. The defining characteristic of goods falling under this classification is their substantial thickness, exceeding 6.3 mm. These are generally thicker forms of flat-rolled aluminum products used in a variety of industrial applications where structural integrity and robustness are paramount, such as heavy-duty construction, manufacturing of large components, or as raw material for further processing into more complex items.

It is crucial to distinguish this category from its sibling, 7606.91.30.95, which encompasses aluminum plates, sheets, and strip of the same non-alloyed, non-clad composition but with a thickness of 6.3 mm or less. The trade professional must carefully measure the thickness of the aluminum product to ensure correct classification, as this physical attribute is the sole differentiating factor between these two specific subheadings.

As this node represents a "leaf" in the HTS classification tree, there are no further subdivisions beneath it. Therefore, the classification of an article as 7606.91.30.55 hinges entirely on meeting the criteria of being a non-alloyed, non-clad aluminum plate, sheet, or strip with a thickness demonstrably greater than 6.3 mm. Examples could include thick aluminum plates used in shipbuilding, heavy machinery fabrication, or for large-scale structural components.
