7004.20.20.20 - Measuring 5 mm and over in thickness

This HTS category, 7004.20.20.20, specifically covers drawn or blown glass sheets that are colored throughout the mass (body tinted), opacified, flashed, or possess an absorbent, reflecting, or non-reflecting layer, and are in a rectangular shape measuring 5 mm and over in thickness. These characteristics denote glass that has undergone a manufacturing process to impart specific visual or functional properties beyond basic transparency, and it is distinguished by its substantial thickness.

The key differentiator for this category is the thickness specification of "5 mm and over." This explicitly distinguishes it from its sibling category, 7004.20.20.10, which covers similar types of treated glass sheets but measures less than 5 mm in thickness. Therefore, the physical dimension of the glass sheet is the primary criterion for differentiating between these two closely related classifications.

As this is a leaf node within the HTS structure, there are no further subcategories. Classification within 7004.20.20.20 is determined by the presence of body tinting, opacification, flashing, or a surface layer, its rectangular shape, and its thickness of 5 mm or greater. This ensures precise categorization for customs purposes, facilitating accurate duty assessment and trade statistics.
