9902.07.98 - Mixtures of Disperse Blue ANT (Br) (N-[5-(acetylamino)-4-[2- (2-bromo-4,6-dinitrophenyl)diazenyl]-2-methoxyphenyl]-N- (2-methoxy-2-oxoethyl)-glycine, methyl ester) (CAS No. 88938-51-6); Disperse Green GNA (N-[5-(acetylamino)-2-methoxy-4-[2-(5-nitro-2,1- benzisothiazol-3-yl)diazenyl]phenyl]-N-(2-methoxy-2-oxoethyl)-glycine, methyl ester) (CAS No. 1235882-84-4); Disperse Yellow FC60954 (4-[2-(5-cyano-1,6-dihydro-2-hydroxy- 1,4-dimethyl-6-oxo-3-pyridinyl)diazenyl]-benzoic acid, 2-phenoxyethyl ester) (CAS No. 88938-37-8); and Disperse Red DYNS 2246 (N-[4-[2-(2-cyano-4-nitrophenyl)dia- zenyl]phenyl]-N-(phenylmethyl)-B-alanine, 2-oxopropyl ester ) (CAS No. 1021394-33-1) (provided for in 3204.11.35)

This HTS code, 9902.07.98, covers specific mixtures of synthetic organic colorants designated as Disperse Blue ANT (Br), Disperse Green GNA, Disperse Yellow FC60954, and Disperse Red DYNS 2246. These are specialized dyestuffs, primarily used for coloring synthetic fibers like polyester, acetate, and nylon. Their classification within Chapter 99 signifies they are subject to temporary legislation or modifications, distinct from their potential base classification under Chapter 32 (which would typically cover dyes and pigments).

Unlike the broader categories found at the root of the HTS database, such as live animals (Chapter 01), which are organized by broad commodity groups, this entry is highly specific. It focuses on a particular set of chemical compounds with defined CAS numbers and chemical names. The distinction lies in the fact that this code is not for a general class of goods but for these precisely identified dye mixtures, indicating they are subject to special trade provisions or restrictions that deviate from standard tariff treatments.

As a leaf node within the HTS, 9902.07.98 has no subcategories. The classification is definitive for the described mixtures. The inclusion of the parenthetical reference to 3204.11.35 indicates that these specific mixtures, when not subject to the special provisions of Chapter 99, would ordinarily fall under headings related to synthetic organic dyestuffs. Therefore, the primary classification criteria here are the precise chemical composition and the application of temporary trade regulations governing these particular dyes.
