3206.42.00.00 - Lithopone and other pigments and preparations based on zinc sulfide

This HTS category, 3206.42.00.00, encompasses lithopone and other pigments and preparations that are primarily based on zinc sulfide. Lithopone itself is a white pigment, a chemical compound of barium sulfate and zinc sulfide, known for its opacity and brilliance. This classification also extends to other inorganic coloring matters and preparations that do not fall under headings 3203, 3204, or 3205, provided their primary basis is zinc sulfide. These products are used in a variety of applications, including paints, coatings, plastics, and rubber.

Within the broader heading 3206, this specific subheading is distinguished from its sibling, 3206.41.00.00, which covers ultramarine and preparations based on it. Ultramarine is a distinct blue pigment derived from lapis lazuli or synthesized. Therefore, the key differentiator for 3206.42.00.00 is the chemical composition and the presence of zinc sulfide as the principal coloring component, excluding pigments with a base of ultramarine.

As this is a leaf node within the HTS structure, there are no further subcategories to introduce. Classification under 3206.42.00.00 is determined by the identification of lithopone or other pigments where zinc sulfide is the primary inorganic coloring agent. The "preparations" aspect of the description refers to mixtures or formulations where zinc sulfide pigments are the significant component, affecting the color or properties of the final product.
