9902.08.38 - Disodium 7-anilino-4-hydroxy-3-({2-methoxy-5-methyl-4-[(4-sulfonatophenyl) diazenyl] phenyl} diazenyl)-2-naphthalenesulfonate (Direct violet 9) (CAS No. 6227-14-1) (provided for in subheading 3204.14.50)

This HTS classification, 9902.08.38, specifically covers Direct Violet 9, a synthetic organic dye. Its formal chemical name is Disodium 7-anilino-4-hydroxy-3-({2-methoxy-5-methyl-4-[(4-sulfonatophenyl) diazenyl] phenyl} diazenyl)-2-naphthalenesulfonate, and it is identified by CAS Number 6227-14-1. This classification falls under Chapter 99, which deals with temporary legislation and trade agreement modifications, indicating that its inclusion here is likely due to specific trade policy or import restriction measures rather than its inherent product category under the standard HTS structure.

Given that this is a leaf node within Chapter 99, there are no further subcategories to introduce. Instead, the focus is on its specific application and the special provisions it falls under. While the description references its provision under subheading 3204.14.50 (which covers other synthetic organic dyestuffs), the 9902 code signifies a temporary or specialized import status. This distinguishes it from the general classification of dyes in Chapter 32, highlighting that goods classified here are subject to additional regulatory considerations beyond their basic product identification.
