3204.17.90.18 - Pigment red 57:1, dry, presscake or aqueous slurry

This HTS category, 3204.17.90.18, specifically covers Pigment Red 57:1. This pigment is a synthetic organic coloring matter. The classification applies regardless of whether the pigment is in its dry powder form, as a presscake (a consolidated form after filtration), or as an aqueous slurry (a suspension of particles in water). It is essential for trade professionals to note that the HTS system requires precise identification of the specific pigment in question.

Distinguishing this entry from its siblings, such as Pigment Blue 15:3 (3204.17.90.02) or Pigment Green 7 (3204.17.90.10), hinges on the chemical identity and color index of the coloring matter. While all fall under "Other" pigments and preparations based thereon within the broader synthetic organic coloring matter chapter, the exact chemical composition and resulting color are the critical differentiating factors for customs purposes. Preparations based on these pigments, like those noted for Pigment Blue 15:3 (3204.17.90.03), are classified separately, indicating that this sub-heading is reserved for the pigment itself in its various physical states.

As this is a leaf node, there are no further subcategories to introduce. The classification concludes with the specific identification of Pigment Red 57:1 in its common commercial forms. For practical classification, understanding the pigment's chemical name and its common designation as Pigment Red 57:1 is paramount, along with its physical state as dry, presscake, or aqueous slurry.
