3204.19.11.00 - Solvent black 2, 3, 27, 28, 29, 34, 35; Solvent blue 45, 49, 51, 53, 56, 67, 97; Solvent brown 1, 28, 42, 43, 44; Solvent green 4, 5, 7, 19, 27, 28; Solvent orange 45, 54, 59, 62, 63, 67; Solvent red 7, 18, 19, 23, 27, 35, 89, 92, 100, 110, 118, 119, 124, 125, 127, 129, 130, 131, 132, 160, 162; Solvent violet 2, 23, 24; and Solvent yellow 1, 30, 32, 48, 64, 89, 93, 98, 160

This HTS category encompasses a specific group of synthetic organic coloring matters classified as solvent dyes. Solvent dyes are characterized by their solubility in organic solvents and their primary application in coloring materials such as plastics, waxes, oils, and certain synthetic fibers. The detailed listing within the description provides an exhaustive enumeration of individual solvent dyes and their assigned numerical designations that fall under this specific classification.

The distinction between this subheading and its siblings lies in the precise chemical identity and numbering of the solvent dyes. For instance, sibling category 3204.19.06.00 specifically covers Solvent yellow dyes numbered 43, 44, 85, and 172. This current category, however, applies to a different, broader set of solvent dyes, including various solvent blacks, blues, browns, greens, oranges, reds, violets, and yellows, as listed in the description. The key differentiating factor is the specific dye name and number.

As this is a leaf node within the HTS structure, there are no further subdivisions or subcategories. Therefore, the classification is definitive for the listed solvent dyes. Importers and exporters should meticulously verify that the imported or exported product corresponds exactly to one of the enumerated solvent dyes to ensure accurate classification under 3204.19.11.00. Any solvent dyes not specifically named in this provision would need to be classified under alternative, more general "Other" subheadings within the broader solvent dye category.
