3207.40.10.00 - Ground or pulverized

This HTS subcategory, 3207.40.10.00, specifically covers glass frit and other glass that has been processed into a ground or pulverized form. This refers to finely divided glass particles, often resembling powder or dust, created through mechanical grinding or crushing. These preparations are primarily utilized as essential components in various industrial applications, notably within the ceramic, enamelling, and glass manufacturing sectors. Their finely milled nature allows for their incorporation into glazes, enamels, and other formulations to achieve desired aesthetic and functional properties, such as color, opacity, or surface finish.

Distinguishing this category from its sibling, 3207.40.50.00 "Other," is crucial for accurate classification. While both fall under the broader heading of "Glass frit and other glass, in the form of powder, granules or flakes," the "Other" category would encompass glass in these particulate forms that are not specifically ground or pulverized. This could include larger granules, flakes, or other less refined particulate forms of glass frit or glass, where the processing method differs from fine grinding. The key differentiator lies in the degree of particle size reduction achieved through the grinding or pulverizing process.

As this is a leaf node, there are no further subcategories within 3207.40.10.00. Therefore, classification is determined by whether the glass frit or glass product meets the criteria of being "ground or pulverized." Importers and exporters should carefully examine the physical form of the material. If the product is a glass frit or other glass preparation in a powder or dust-like consistency resulting from grinding, it falls under this specific code. If the product is in a granular or flake form that is not the result of a pulverizing process, it would be classified under the "Other" sibling category.
