3206.49.30.00 - Preparations based on zinc oxides

This HTS category, 3206.49.30.00, specifically covers preparations where zinc oxide is the primary coloring matter. These preparations are utilized as pigments and colorants across various industrial applications. Examples include zinc oxide-based paints, inks, or masterbatches designed for coloring plastics, where the zinc oxide provides opacity, UV protection, or a specific hue. The classification emphasizes the form and intended use as a coloring preparation, distinct from raw zinc oxide itself.

It is crucial to distinguish these zinc oxide preparations from their sibling categories. Category 3206.49.10.00 pertains to concentrated pigment dispersions specifically within plastics materials. Category 3206.49.20.00 deals with preparations based on iron oxides, which have different chemical compositions and color properties. Furthermore, preparations based on carbon black (3206.49.40.00) and those utilizing hexacyanoferrates (3206.49.55.00) represent distinct chemical families of coloring agents. The current category isolates preparations where zinc oxide is the defining component.

As this is a leaf node, there are no further subdivisions under 3206.49.30.00. Classification within this code hinges on the confirmation that the preparation's primary coloring agent is zinc oxide, and it is not a specialized pigment dispersion in plastics, an iron oxide-based preparation, a carbon black preparation, or a hexacyanoferrate preparation. The scope is therefore precisely defined by the presence and primary function of zinc oxide as a coloring matter.
