7005.21.10.10 - Measuring less than 5 mm in thickness

This HTS category, 7005.21.10.10, specifically classifies float glass and surface ground or polished glass sheets that are less than 5 mm in thickness. These sheets are characterized by being colored throughout the mass (body tinted), opacified, flashed, or merely surface ground. The "not otherwise worked" clause indicates that further processing, such as cutting to shape or drilling, would place the glass into a different HTS category.

The key differentiator for this subcategory is its strict adherence to a thickness specification. It is distinguished from its sibling category, 7005.21.10.30, which covers glass of the same type but measuring 5 mm or more but less than 10 mm in thickness. Therefore, the precise measurement of the glass sheet's thickness is the primary criterion for its classification within either of these two categories.

As this node represents a leaf node within the HTS structure, there are no further subcategories to introduce. The classification ends here, with the defining characteristics being the material type (float glass or surface ground/polished glass), its state (in sheets, not otherwise worked), the specific surface treatment or body coloring, and crucially, its thickness of less than 5 mm.
