7606.92.60.55 - With a thickness of more than 6.3 mm

This HTS category, 7606.92.60.55, specifically classifies aluminum plates, sheets, and strip that are of aluminum alloys and have a thickness exceeding 6.3 mm. These products are typically used in a wide range of industrial applications where robust and rigid aluminum structures are required, such as in construction, heavy machinery, shipbuilding, and the manufacturing of large structural components. The defining characteristic for this classification is the substantial thickness, indicating a product designed for structural integrity rather than flexibility.

While the parent category encompasses all aluminum plates, sheets, and strip over 0.2 mm thick that are not of pure aluminum, this subcategory narrows the focus to those made from aluminum alloys and meeting a specific thickness threshold. The distinction from other subcategories under 7606.92 (Other: Of aluminum alloys) lies solely in the specified thickness.

The sole subcategory, 7606.92.60.95, classifies similar aluminum alloy plates, sheets, and strip but differentiates based on a thickness of 6.3 mm or less. This highlights that the critical factor for distinguishing within this branch of the tariff schedule is the precise dimensional attribute of the aluminum product, with thicker items falling into this category and thinner ones into the sibling.
