7005.21.20.00 - Measuring 10 mm or more in thickness

This HTS classification covers float glass and surface ground or polished glass sheets that are colored throughout the mass, opacified, flashed, or merely surface ground, and specifically measure 10 millimeters or more in thickness. This category encompasses glass that has undergone a process to impart color or opacity uniformly within the material, or has been treated on the surface for aesthetic or functional purposes. The defining characteristic for inclusion here, distinguishing it from its sibling, is the substantial thickness of the glass sheet.

This category is distinguished from HTS 7005.21.10 primarily by its thickness dimension. While both classifications pertain to colored, opacified, flashed, or surface ground glass sheets, this node specifically captures those with a thickness of 10 mm or greater. Therefore, a crucial step in classifying such glass is to accurately measure its thickness to determine the correct subheading.

As a leaf node, this classification does not have further subcategories. The classification is complete at this level, and goods meeting the description of float or surface ground/polished glass sheets, colored throughout the mass, opacified, flashed, or merely surface ground, with a thickness of 10 mm or more, will be assigned to HTS Code 7005.21.20.00. Practical examples might include thick, tinted architectural glass for windows, or opaque glass panels for decorative applications that meet the specified thickness requirement.
