9902.08.07 - Mixtures of Disperse Blue 77 (1-Anilino-4,5-dihydroxy-8-nitro-9,10-anthraquinone) (CAS No. 20241-76-3); Disperse Blue 60 M (4,11-Diamino-2-(3-methoxypropyl)-1H- naphtho[2,3-f]isoindole-1,3,5,10(2H)-tetrone) (CAS No. 12217-80-0); and Disperse Yellow 71 (9 (or 10)-Methoxy-7H-benzimidazo[2,1-a]benz[de]iso- quinolin-7-one) (CAS No. 68296-59-3) (provided for in subheading 3204.11.35)

This HTS category, 9902.08.07, specifically covers certain mixtures of disperse dyes, namely Disperse Blue 77, Disperse Blue 60 M, and Disperse Yellow 71. These are synthetic organic dyes commonly used for coloring synthetic fibers, particularly polyester. The inclusion of CAS numbers in the description provides precise chemical identification, aiding in accurate classification. The reference to subheading 3204.11.35 indicates that these mixtures are further classified within a broader group of synthetic organic coloring matter, specifically those derived from anthraquinone and isoindole structures.

Given that this is a leaf node, there are no subcategories to introduce. The primary distinction of this specific code lies in the precise composition of the dye mixtures it enumerates. Unlike broader categories that might cover general dyes or coloring matter, 9902.08.07 is highly specific, enumerating particular chemical entities. Its placement within Section XXII, Chapter 99, highlights that these are goods subject to temporary legislation or modifications, likely related to trade agreements or specific import restrictions, setting it apart from the permanent tariff structures found in other chapters.
