3204.17.90.30 - Pigment red 179

This HTS classification covers "Pigment red 179," a specific synthetic organic coloring matter. As a "pigment," it is characterized by its insolubility in the medium it colors, imparting color by dispersion. Pigment red 179 falls under the broader category of synthetic organic coloring matter, which are man-made chemical compounds designed for imparting color, distinct from natural dyes or inorganic pigments.

This specific sub-heading, 3204.17.90.30, is distinct from its siblings by precisely identifying "Pigment red 179." For example, while sibling categories like 3204.17.90.02 and 3204.17.90.03 cover specific forms of "Pigment blue 15:3" and its preparations, or 3204.17.90.10 covers "Pigment green 7," this entry is exclusively for the red pigment identified as Pigment red 179. The preceding "Other" categories at the 3204.17.90 level indicate that this specific red pigment is not otherwise specified under prior sub-classifications within this group.

Since this node is a leaf node within the HTS structure, it does not have further subcategories. The classification concludes with the precise identification of Pigment red 179, meaning that any shipment of this particular pigment, regardless of its specific physical form (e.g., powder, paste), would be classified here, provided it meets the criteria of a synthetic organic coloring matter and is not specifically excluded by chapter notes or further specifications within the tariff.
