7606.11.30.60 - With a thickness of 6.3 mm or less

This HTS category, 7606.11.30.60, specifically classifies rectangular or square plates, sheets, and strip of aluminum, not alloyed and not clad, that have a thickness of 6.3 mm or less. These are typically flat-rolled aluminum products used in a wide array of industrial and commercial applications where precise dimensions and material purity are important. The emphasis is on unalloyed aluminum, meaning it primarily consists of aluminum with minimal other metallic elements.

This classification is distinguished from its sibling category, 7606.11.30.30, by its physical dimension. While both fall under rectangular or square, not alloyed, not clad aluminum sheet, the key differentiator is thickness. Category 7606.11.30.60 applies only to those aluminum products with a maximum thickness of 6.3 mm, whereas 7606.11.30.30 covers those exceeding this limit. This precise thickness threshold is a critical factor for customs valuation and regulatory compliance.

As this node represents a leaf node within the HTS structure, there are no further subcategories. Therefore, classification under 7606.11.30.60 is final for qualifying goods. Importers and exporters should ensure the material is indeed unalloyed and not clad, and that its thickness falls within the specified range (up to and including 6.3 mm) to correctly apply this classification.
