3204.13.10.00 - Basic black 7; Basic blue 41, 45, 48, 55, 62, 66, 70, 71, 78, 80, 81, 120, 141; Basic green 6, 8; Basic orange 30, 35, 36, 37, 43, 44, 48; Basic red 22, 23, 28, 29, 43, 44, 46, 58, 75, 100; Basic violet 2, 22, 25, 37, 38; and Basic yellow 19, 23, 24, 25, 39, 40, 45, 54, 56, 63, 70, 77

This HTS category, 3204.13.10.00, encompasses a specific range of basic synthetic organic dyes. These are characterized by their cationic nature and their ability to form salts with acids, leading to good solubility in water. The description lists numerous specific dyes by their common names and Color Index (C.I.) numbers, including various shades of black, blue, green, orange, red, violet, and yellow. These dyes are primarily used for coloring materials such as textiles (cotton, silk, acrylics), paper, and leather, where their affinity for negatively charged substrates is advantageous.

Distinguishing this category from its siblings is crucial for accurate classification. For instance, while this node enumerates a broad selection of basic dyes, sibling categories such as 3204.13.20.00 and 3204.13.25.00 are reserved for more narrowly defined groups of basic dyes, like "Basic orange 22 and Basic red 13" or specific blue and yellow variants. Similarly, 3204.13.45.00 isolates specific compounds like Methylene blue and "Basic blue 147." This current node functions as a catch-all for the numerous other basic dyes not individually specified in these distinct sibling headings.

As this is a leaf node within the HTS structure, there are no further subcategories to introduce. Therefore, the focus remains on clearly identifying the broad array of basic dyes covered here, differentiating them from the more specific groupings found at the same level. Classification under 3204.13.10.00 is appropriate when a basic synthetic organic dye is not explicitly listed in any other subdivision of 3204.13.
