3204.15.25.00 - Vat red 1

This HTS category, Vat red 1, specifically encompasses the vat dye identified as "Vat red 1." Vat dyes are a class of water-insoluble dyes that are applied to cellulosic fibers in a soluble, reduced (leuco) form, and then oxidized back to their insoluble, colored state within the fiber. This process results in excellent wash and lightfastness properties.

The distinction of "Vat red 1" from its sibling categories lies in its precise chemical identity and common naming convention within the dye industry. While other siblings list multiple vat dyes by their common names and Colour Index Numbers, this subheading isolates "Vat red 1" for specific classification. This granular approach is crucial for accurate duty assessment, ensuring that specific dyes with potentially different trade values or applications are correctly categorized. As this is a leaf node in the HTS classification, there are no further subcategories. Classification under this heading relies on the confirmation that the imported product is indeed "Vat red 1," as per established chemical and trade nomenclature.
