Last updated: September 2026 dataGround, pulverized, and powdered glass frit is a critical intermediate in ceramic glazes, enamel coatings, and specialty glass manufacturing, where precise particle size and chemical composition determine end-product performance. The US schedule subdivides this heading into ground or pulverized glass (3207401000) and other powdered or flaked forms not elsewhere specified (3207405000), with a residual line at 3207400000. Germany leads US supply, followed by Mexico and Canada, reflecting the concentration of advanced ceramic and specialty glass industries in those markets. Importers should verify whether specific formulations trigger classification under adjacent headings for ceramic pigments or prepared opacifiers.

The distinction turns on processing method: 3207401000 covers glass that has been specifically ground or pulverized, while 3207405000 captures other powdered, granulated, or flaked forms not elsewhere specified. If the product is produced by a melt-quench-grind process typical of frit manufacture, the ground/pulverized line is generally appropriate, but the specific physical form and end-use context should be reviewed with a licensed customs broker.
Germany, Mexico, and Canada are the top suppliers of glass frit to the US. Imports from Mexico and Canada may benefit from USMCA treatment depending on origin qualification. No broadly applicable Section 301 or antidumping orders are known to target glass frit specifically, but importers should confirm current remedy status with CBP or a customs broker, as product-specific orders can change.
