HS Code for Glass pigment

Glass pigments are classified under HS code 3207.10, which covers prepared pigments, prepared opacifiers, and prepared colors. These substances are specifically formulated for use in the ceramic, enameling, or glass industries. The classification is based on the chemical preparation and the intended industrial application. Unlike general-purpose dyes or pigments found in heading 3204 or 3206, the items in 3207 are vitrifiable, meaning they are designed to be fused with glass or ceramic surfaces at high temperatures. This technical requirement necessitates a separate classification to distinguish industrial glass colorants from standard paints or organic pigments. The Harmonized System groups these based on their specialized chemical composition, which often includes metallic oxides or salts mixed with a flux to facilitate melting and bonding with the glass substrate. This code is critical for manufacturers of colored glass, stained glass, and decorative glassware who require consistent chemical inputs for their production processes.

Products Included

• Prepared pigments for coloring glass melt
• Vitrifiable glass enamels
• Glass opacifiers for creating translucent effects
• Metallic oxide preparations for glass staining
• Prepared colors for glass screen printing

Common Misclassification

Glass pigments are often confused with HS code 3204 (synthetic organic coloring matter) or 3206 (other coloring matter like titanium dioxide). The key difference is that 3207.10 is for "prepared" pigments specifically for the glass/ceramic industry, often containing a flux. Another common error is misclassifying these as glass frit, which falls under 3207.40. While frit is also used in glass making, it is a ground glass material rather than a concentrated pigment or opacifier preparation.

FAQ

What is the HS code for glass pigment?

The standard HS code for prepared glass pigments and opacifiers is 3207.10.

Is glass frit classified under this same code?

No, glass frit in the form of powder, granules, or flakes is classified under HS code 3207.40.
