Product classification
HS code for Glass frit: 3207.40
Glass, glass frit and other glass, in the form of powder, granules or flakes.
Classification of glass frit under HS 3207.40
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.

Codes often confused with 3207.40
Common mistake. 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.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
