HS Code for Ceramic glaze

Ceramic glazes and similar preparations are classified under heading 3207. This heading covers prepared pigments, opacifiers, colors, vitrifiable enamels and glazes, engobes, and liquid lustres used in the ceramic, enamelling, or glass industries. Subheading 3207.20 specifically targets vitrifiable enamels and glazes, as well as engobes (slips). These substances are mixtures of silica, fluxes, and metallic oxides that, when applied to a ceramic body and fired, melt to form a glassy, protective, or decorative coating. The classification is determined by the chemical preparation and the intended industrial use. Unlike standard paints or varnishes found in heading 3208, these products must be "vitrifiable," meaning they are designed to be fused by heat during a firing process. This code also includes "slips" or engobes, which are clay-based coatings used to color or smooth the surface of ceramic ware before the final glaze is applied. The products are usually presented in the form of powder, granules, or flakes, or as a suspension in a liquid (such as water or an organic medium).

Products Included

• Vitrifiable ceramic glazes
• Ceramic enamels in powder or liquid form
• Engobes (slips) for ceramic coating
• Vitrifiable preparations for glass decoration
• Prepared glass frits (when formulated as glaze)

Common Misclassification

Ceramic glazes are often misclassified under 3207.10, which is reserved for prepared pigments and opacifiers. While related, glazes are distinct because they form a glassy surface. They are also sometimes confused with 3208 or 3209 (paints and varnishes), but those headings exclude vitrifiable products. Raw materials like untreated clay or silica should be classified in Chapter 25, not 3207.

FAQ

What is the HS code for ceramic glaze?

The HS code for vitrifiable ceramic glazes and engobes is 3207.20. This includes both the powdered and liquid forms of the preparation.

Does this code include the pigments used to color the glaze?

If the pigment is sold separately as a concentrated colorant, it is classified under 3207.10. If it is already mixed into the glaze preparation, the entire mixture is classified under 3207.20.
