3204.17.40.90 - Other

This HTS classification, 3204.17.40.90, is designated for "Other" pigments and preparations based thereon, specifically falling under the broader category of synthetic organic coloring matter. This residual classification captures specific isoindolenine red pigments and certain pigment reds and yellows that are not explicitly enumerated under the preceding subheadings at this level. It serves as a catch-all for qualifying synthetic organic pigments that do not fit into the more narrowly defined categories for Pigment Red 149 or Pigment Red 214.

The distinction between this "Other" category and its siblings is crucial for accurate classification. While 3204.17.40.15 specifically covers Pigment Red 149 (both dry and presscake forms) and 3204.17.40.30 isolates Pigment Red 214, this subheading encompasses other qualified isoindolenine reds, Pigment Red 242, Pigment Red 254, and Pigment Yellow 155 and 183. Importers must carefully review the specific designation of their imported pigment to determine if it is listed in a more precise sibling category before resorting to this residual "Other" classification.

As this is a leaf node, there are no further subcategories within 3204.17.40.90. Therefore, classification into this subheading hinges entirely on whether the pigment in question is a synthetic organic coloring matter, specifically an isoindolenine red pigment, Pigment Red 214, 242, 254, Pigment Red 149 (dry or presscake), or Pigment Yellow 155 or 183, and is not specifically captured by a more granular HTS code elsewhere. Careful examination of product specifications and the chemical identity of the pigment are paramount for correct duty assessment and trade compliance.
