3207.30.00.00 - Liquid lustres and similar preparations

This HTS classification, 3207.30.00.00, specifically covers "Liquid lustres and similar preparations" that are intended for use in the ceramic, enamelling, or glass industries. These preparations are characterized by their liquid form and are typically applied to surfaces to impart a lustrous or decorative finish. They often contain metallic particles, pigments, or chemical compounds that, when fired, create a shimmering or iridescent effect. Examples include liquid gold, platinum preparations, and other metallic-effect decorative coatings used on tableware, tiles, or glass objects.

Distinguishing this category from its siblings, 3207.10.00.00 deals with general prepared pigments, opacifiers, and colors which are not necessarily in liquid form or specifically designed for lustrous effects. Similarly, 3207.20.00.00 encompasses vitrifiable enamels and glazes, engobes (slips), and related preparations, which are primarily functional or decorative coatings designed to fuse with the substrate during firing to create a durable surface, rather than focusing on a specific "lustre" effect. The other sibling, 3207.40, covers glass frit and glass in particulate forms, which are raw materials for enamels and glazes, not finished decorative preparations themselves.

As a leaf node within Chapter 32, this HTS code does not have further subcategories. Therefore, classification under 3207.30.00.00 depends on the preparation's liquid nature and its intended application for creating lustrous or similar decorative finishes in the specified industries, rather than its composition as a raw material or a general coloring agent.
