HS Code for Glass frit

Glass frit is classified under HS code 3207.40. This classification is unique because it places glass frit within Chapter 32, which covers tanning or dyeing extracts, pigments, and other coloring matter, rather than Chapter 70 (Glass). The reason for this is that glass frit is primarily used as a raw material in the production of enamels, glazes, and ceramic colors. Glass frit is produced by melting a specific mixture of raw materials and then rapidly quenching the molten glass in water, which causes it to shatter into small, friable fragments. These fragments are then ground into a fine powder or granules. The HS code 3207.40 specifically identifies glass in the form of powder, granules, or flakes. This classification is essential for the ceramics and glass-coating industries, as it distinguishes the material from finished glass products or glass waste. The chemical composition of the frit, often containing fluxing agents like borax or lead, is designed to lower the melting point for application on other surfaces.

Products Included

• Crushed glass frit
• Granulated glass for glazes
• Glass flakes for industrial coatings
• Powdered glass for ceramic enamels
• Vitreous enamels in frit form

Common Misclassification

Glass frit is often misclassified under HS code 7001.00, which covers cullet and other waste and scrap of glass. While both may appear as broken glass, cullet is waste material intended for remelting into glass products, whereas frit is a prepared chemical product for glazes. Another common error is 3207.10, which covers prepared pigments and opacifiers; however, 3207.40 is the specific sub-heading for the frit itself. Importers should also avoid 3207.20, which is for vitrifiable enamels and glazes that may contain frit but are more complex mixtures.

FAQ

What is the HS code for glass frit?

The HS code for glass frit in the form of powder, granules, or flakes is 3207.40.

Is recycled glass considered glass frit?

Generally, no. Recycled glass intended for melting is classified as cullet under 7001.00, whereas glass frit (3207.40) is a manufactured product used for glazes and enamels.
