3204.19.25 - Other

This HTS category, 3204.19.25, encompasses "Other" solvent dyes and preparations based thereon that do not fall under more specific subheadings within the solvent dye classification. It serves as a residual category for solvent coloring matter that exhibits solubility in organic solvents, intended for imparting color to various materials, and whose precise chemical composition or specific application is not detailed in preceding subheadings. These dyes are distinct from pigments in that they dissolve rather than disperse in the application medium.

This subheading distinguishes itself from its sibling, 3204.19.20, which specifically covers solvent dyes and preparations that are "Products described in additional U.S. note 3 to section VI." This means 3204.19.25 is for solvent dyes and preparations that *do not* meet the criteria outlined in that particular U.S. additional note, likely relating to specific chemical structures or performance characteristics.

The subcategories within 3204.19.25 further refine the classification of these "Other" solvent dyes. They include specific named dyes such as Solvent Red 135, Solvent Orange 60, and Solvent Yellow 33, allowing for precise identification and tariff treatment of commonly traded solvent coloring agents. The final subcategory, 3204.19.25.95, serves as a further residual category for any other solvent dyes and preparations based thereon that do not fit into the more specifically named subcategories.
