7004.90.30.10 - Measuring over 3.5 but not over 5 mm in thickness

This HTS classification covers drawn or blown glass sheets that are otherwise unworked, meaning they have not undergone significant alteration beyond their initial formation. Specifically, these are glass sheets of rectangular shape, falling under the broader category of "Other glass" within drawn and blown glass. The key defining characteristics for this subcategory are the thickness and area.

This particular classification is distinguished from its sibling category, 7004.90.30.20, by its specific thickness. While both fall under "Measuring over 3.5 mm in thickness," this node is for glass sheets measuring *over 3.5 mm but not over 5 mm* in thickness. The sibling category, conversely, covers glass sheets exceeding 5 mm in thickness. Both classifications also share the requirement of being rectangular and having an area not exceeding 0.65 m², with this specific node further narrowing the area to not exceeding 0.26 m².

As this is a leaf node within the HTS structure, there are no further subcategories to introduce. The classification is complete at this level based on the combined criteria of glass type (drawn/blown, unworked), shape (rectangular), thickness (over 3.5 mm but not over 5 mm), and area (not over 0.26 m²). Examples within this category would include standard window glass panes or sheet glass intended for applications where these precise dimensional specifications are critical, and no further processing such as cutting to specific shapes or application of specialized coatings has occurred.
