HS Code for Vitrifiable enamel

Vitrifiable enamels are classified under HS code 3207.20. This heading covers vitrifiable enamels and glazes, engobes (slips), and similar preparations used in the ceramic, enamelling, or glass industries. These substances are essentially glass-forming compositions that, when applied to a substrate and fired at high temperatures, melt to form a vitreous (glassy) coating. The classification is determined by the chemical composition and the intended application method (thermal fusion). Under Chapter 32, which deals with tanning, dyeing, and coloring matter, heading 3207 is reserved for specialized preparations used for coating surfaces that require heat treatment, distinguishing them from standard paints or varnishes that dry through evaporation or chemical reaction at room temperature.

Products Included

• Powdered glass enamels for steel or cast iron
• Ceramic glazes for pottery and tiles
• Engobes (clay-based slips for coloring ceramics)
• Vitrifiable colors for glass decoration
• Liquid lusters for ceramic application

Common Misclassification

The most frequent misclassification for vitrifiable enamel is HS code 3208 or 3209, which cover traditional paints and varnishes. The key difference is the binder and the curing process; 3207 products are inorganic and require kiln firing, whereas 3208/3209 are organic polymer-based. Another error is confusing these with HS code 3207.10 (prepared pigments, opacifiers, and colors). While both are used in ceramics, 3207.10 refers to the coloring agents themselves, whereas 3207.20 refers to the complete coating (enamel or glaze) that forms the surface layer. Finally, glass frit in bulk is classified under 3207.40, not 3207.20.

FAQ

What is the HS code for vitrifiable enamel?

The HS code for vitrifiable enamels and glazes is 3207.20.

What is the difference between 3207.10 and 3207.20?

3207.10 is for the pigments and opacifiers used to add color, while 3207.20 is for the actual enamel or glaze preparation that melts to form the protective or decorative glassy coating.
