7616.99.51.20 - Laminated goods consisting of 2 or more flat-rolled sheets of aluminum held together with an adhesive or having a core of non-metallic material

This HTS category, 7616.99.51.20, specifically classifies laminated goods composed of two or more flat-rolled sheets of aluminum. The defining characteristic is the method of assembly: these sheets are either bonded together using an adhesive or incorporate a core of non-metallic material. This classification is distinct from other "other" articles of aluminum at this level, as it focuses on the composite, multi-layered nature of the aluminum product.

Unlike sibling categories such as ladders (7616.99.51.30), venetian blinds (7616.99.51.40), or hangers and supports (7616.99.51.50), which are defined by their specific function and form, this category is determined by the material construction – specifically, a lamination of aluminum sheets with an intermediary layer. This broad scope ensures that various multi-layered aluminum products not specifically enumerated elsewhere are appropriately classified. As this is a leaf node, there are no further subdivisions.
