3204.17.40 - Isoindolenine red pigment; Pigment red 214, 242, 254; Pigment red 149 dry and pigment red 149 presscake; and Pigment yellow 155, 183

This HTS classification, 3204.17.40, specifically covers certain high-performance organic pigments, primarily within the isoindolenine and quinacridone families. It encompasses Pigment Red 214, Pigment Red 242, Pigment Red 254, and specific forms of Pigment Red 149 (both dry and presscake), along with Pigment Yellow 155 and Pigment Yellow 183. These pigments are known for their excellent lightfastness, weather resistance, and vibrant color properties, making them suitable for demanding applications such as automotive coatings, high-quality plastics, and specialized inks.

Distinguishing this category from its siblings is crucial for accurate classification. For instance, while sibling category 3204.17.04 lists a broad range of red pigments, it does not include the specific isoindolenine or quinacridone reds detailed here. Similarly, 3204.17.08.00 covers different red and yellow pigments, and 3204.17.20.00 addresses un-prepared copper phthalocyanine. The "Other" sibling category is a residual catch-all for pigments not otherwise specified.

The subcategories under 3204.17.40 provide further granularity for these specific pigments. 3204.17.40.15 isolates Pigment Red 149, allowing for specific duty rates or statistical tracking. 3204.17.40.30 similarly focuses on Pigment Red 214. The residual category, 3204.17.40.90, captures any other pigments that meet the broader description but are not explicitly listed in the more specific subheadings, ensuring comprehensive coverage within this pigment group.
