HS Code 3207.40 – Glass; glass frit and other glass, in the form of powder, granules or flakes
HS code 3207.40 is the 6-digit subheading for glass, glass frit and other glass, in the form of powder, granules or flakes. It is used for glass frit for glazes, glass powder for enamels, glass flakes for coatings, glass granules for abrasives and low-melt glass powder.
What HS 3207.40 covers
This HS code covers glass in the form of powder, granules, or flakes, with glass frit being a prominent example. Glass frit is essentially ground glass, often specially formulated with specific melting points and chemical compositions. These comminuted glass materials serve as crucial intermediate products in various industries. They are extensively used in the production of glazes and enamels (as a base material), in specialized coatings, for sealing glass-to-metal or glass-to-ceramic components, and in some abrasive applications. International trade involves glass manufacturers and specialty chemical companies. Importers are typically manufacturers of ceramics, electronics, and coatings who utilize these glass forms for their unique properties.

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).
