3204.15.20.00 - Vat brown 3; Vat orange 2, 7; and Vat violet 9, 13

This HTS category specifically classifies certain vat dyes, including Vat brown 3, Vat orange 2, Vat orange 7, Vat violet 9, and Vat violet 13. Vat dyes are a class of insoluble synthetic dyes that are applied to textiles in a reduced, soluble form (leuco form) and then oxidized back to their insoluble state within the fiber, resulting in excellent wash and lightfastness. These particular dyes are distinguished by their specific chemical structures and resulting colors, making them suitable for a range of textile dyeing applications.

Within the broader category of vat dyes, this HTS code differentiates itself from sibling categories by listing specific, individual vat dye designations. For instance, sibling categories may cover synthetic indigo (Vat blue 1), other specific vat reds, or broader groups of solubilized vat dyes and various vat colors listed by name and Colour Index Number. The absence of further subcategories indicates that this HTS code represents a specific, terminal classification for these named vat dyes, with no further subdivisions required for customs purposes.
