7005.21.10.30 - Measuring 5 mm or more but less than 10 mm in thickness

This HTS category, 7005.21.10.30, specifically classifies float glass and surface ground or polished glass sheets that are colored throughout the mass (body tinted), opacified, flashed, or merely surface ground, and crucially, measure 5 mm or more but less than 10 mm in thickness. These are essentially flat glass products where the coloration or opacity is integral to the glass itself, not a surface coating, and they have undergone basic finishing processes like grinding or polishing.

This distinction is critical when comparing with its sibling category, 7005.21.10.10, which covers similar types of colored or opacified glass but is limited to those measuring less than 5 mm in thickness. Therefore, the defining factor between these two at this level is the precise thickness range, ensuring accurate classification for sheets that fall within the 5 mm to just under 10 mm spectrum.

As this classification represents a leaf node within the HTS structure, there are no further subcategories. Classification to this level signifies that the product's characteristics, including its material (glass), manufacturing process (float glass, ground or polished), inherent visual property (colored, opacified, flashed), and specific thickness range (5 mm to less than 10 mm), have been fully defined, and no further breakdown is required under this heading.
