7005.29.18.10 - Measuring less than 5 mm in thickness

This HTS category, 7005.29.18.10, specifically classifies sheets of float glass and surface ground or polished glass that are not otherwise worked, excluding wired glass. The defining characteristic for this subdivision is that the glass measures less than 5 mm in thickness. These sheets are imported or exported in their basic form, potentially with added layers for reflection, absorption, or non-reflection, but without further fabrication or shaping.

It is crucial to distinguish this category from its sibling, 7005.29.18.50. While both fall under "Measuring less than 10 mm in thickness" and "Measuring over 0.65 m2 in area," this particular code is for glass with a thickness strictly below 5 mm. The sibling category encompasses glass that is 5 mm or more in thickness but still less than 10 mm. Therefore, the precise measurement of the glass's thickness is the key differentiator for correct classification between these two codes.

As this is a leaf node within the HTS structure, there are no further subcategories. Classification at this level is determined by the material (float glass or surface ground/polished glass), the form (sheets, not otherwise worked), the absence of wire, the overall area (over 0.65 m2), and crucially, the thickness (less than 5 mm). Importers and exporters must ensure their product precisely meets all these criteria to avoid misclassification.
