3204.12.05.00 - Acid black 210 powder and presscake

This HTS classification covers Acid black 210, specifically in its powder and presscake forms. Acid dyes are water-soluble anionic dyes that are applied to substrates like wool, silk, nylon, and modified acrylic fibers from an acidic dye bath. The term "acid black" indicates its color and anionic nature, while the "210" is a specific designation within this class of dyes. The powder and presscake forms refer to the physical state of the dye prior to dissolution and application.

This category is distinguished from its siblings by the specific identification of Acid black 210. Other sibling categories list broader ranges of acid dyes or other specific dye names and complex dye mixtures. For instance, 3204.12.13.00 covers Acid violet 19, while 3204.12.17.00 and 3204.12.20.00 encompass extensive lists of other named acid dyes and their preparations. The "Other" category serves as a residual for acid dyes not specifically listed.

As this is a leaf node, there are no further subcategories to introduce. The classification concludes at this specific HTS code, meaning that Acid black 210 in powder and presscake form is directly classified here without further subdivision.
