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

Codes often confused with 3207.40
Common mistake. 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.

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).
