3204.14 - Direct dyes and preparations based thereon:

HTS code 3204.14 encompasses direct dyes and preparations derived from them. Direct dyes are a class of synthetic organic coloring matter characterized by their ability to dye cellulosic fibers, such as cotton, linen, and rayon, directly from an aqueous solution, typically without the need for a mordant. This classification is distinct from other synthetic organic dyes within heading 3204, such as disperse dyes (3204.11) which are used for synthetic fibers like polyester, or acid dyes (3204.12) primarily used for protein fibers like wool and silk.

The subcategories within 3204.14 are established to provide granular detail on specific direct dyes. These subdivisions are often based on the chemical structure or specific color index names of the dyes. For instance, some subcategories list specific direct dyes by their common names and associated color index numbers, facilitating precise identification. The final subcategory, "Other," is a catch-all for direct dyes and preparations not explicitly listed in the more specific enumerations, ensuring that all direct dyes are appropriately classified. This hierarchical structure aids in accurate import and export declarations.
