3204.17.04.30 - Pigment red 166

This HTS category, 3204.17.04.30, specifically classifies **Pigment red 166**. This pigment falls under the broader heading of synthetic organic coloring matter, which are chemical compounds designed to impart color. As part of the "Pigments and preparations based thereon" subdivision, Pigment red 166 is characterized by its primary function as a colorant in various industrial and commercial applications.

Distinguishing Pigment red 166 from its sibling categories involves recognizing the specific HTS codes assigned to other named pigments. For instance, sibling categories might cover Pigment blue 16, Pigment orange 36, or Pigment red 144, each representing a distinct chemical entity with unique coloristic properties and potential uses. The classification hinges on the precise chemical identity and common designation of the pigment.

Since 3204.17.04.30 is a leaf node, it does not have further subcategories. This means that any product falling under this HTS code must specifically be Pigment red 166. If a product were a preparation or mixture containing Pigment red 166 alongside other substances, it might be classified elsewhere depending on the specific formulation and the governing notes of Chapter 32, such as Note 3 to Section VI.
