9902.08.37 - Disodium 7-anilino-3-[(E)-{4-[(E)-(2,4-dimethyl-6-sulfonatophenyl) diazenyl]-2-methoxy-5-methylphenyl} diazenyl]-4-hydroxy-2-naphthalenesulfonate (direct violet 51) (CAS No. 5489-77-0) (provided for in subheading 3204.14.50)

This HTS classification, 9902.08.37, pertains to a specific synthetic organic dye: Disodium 7-anilino-3-[(E)-{4-[(E)-(2,4-dimethyl-6-sulfonatophenyl) diazenyl]-2-methoxy-5-methylphenyl} diazenyl]-4-hydroxy-2-naphthalenesulfonate, also known as direct violet 51. Its Chemical Abstracts Service (CAS) registry number is 5489-77-0. This classification is utilized for special provisions, specifically those related to temporary legislation, modifications under trade agreements, or additional import restrictions proclaimed under Section 22 of the Agricultural Adjustment Act. The description indicates it is to be provided for within subheading 3204.14.50, which covers synthetic organic dyestuffs and preparations thereof.

Unlike the numerous sibling categories found in the initial chapters of the HTS, which primarily deal with live animals and agricultural products, this entry is highly specific. It is not a broad category but rather a designated item under temporary or special provisions, signaling unique regulatory treatment. The distinction lies in its placement within Chapter 99, which is reserved for such specialized classifications, rather than the general commodity chapters. This specific direct violet 51 dye is classified here due to its particular import status or restrictions, separate from its general chemical classification.

As this node is a leaf node, there are no further subcategories. The classification 9902.08.37 represents the most granular level of detail for this particular dyestuff under these special provisions. Classification professionals will need to refer to the specific proclamations or regulations associated with Chapter 99 to understand the full implications and requirements for importing this product, beyond its general classification under dyes.
