HS Code for Glass powder

Glass powder is classified under HS code 3207.40, which covers glass frit and other glass in the form of powder, granules, or flakes. While most glass products are found in Chapter 70, Chapter 32 includes prepared pigments, vitrifiable enamels, and glazes used in the ceramic, enamelling, or glass industries. Subheading 3207.40 is specifically for glass in these fragmented forms that are often used as raw materials for coatings, decorative finishes, or as additives in industrial processes. This classification applies regardless of whether the powder is obtained from crushed waste glass or manufactured specifically as a frit (glass that has been fused, quenched, and pulverized). The key factor is the physical state (powder, granule, or flake) and its typical application in surface treatments or as a component in manufacturing other glass or ceramic products. It is distinguished from cullet (waste glass) by its processed, uniform state intended for specific industrial use.

Products Included

• Glass frit
• Crushed glass powder for enamels
• Glass flakes for protective coatings
• Granulated glass for ceramic glazes
• Silvered glass powder
• Vitrifiable glass granules

Common Misclassification

Glass powder is often misclassified under 7001.00, which covers glass cullet and other waste glass. The distinction lies in the level of processing; 7001.00 is for scrap glass intended for remelting, while 3207.40 is for glass prepared as powder or flakes for use as pigments or glazes. It may also be confused with 2505.10 (silica sand) if the powder is high-purity silica, but if it has been processed into glass first, 3207.40 remains the correct classification.

FAQ

What is the HS code for glass powder?

The HS code for glass powder, granules, and flakes is 3207.40.

Is recycled glass powder under this code?

If the recycled glass has been processed into a specific powder or flake form for use in glazes or coatings, it falls under 3207.40. If it is merely crushed waste, it falls under 7001.00.
