3204.90.00.00 - Other

This HTS category, 3204.90.00.00, serves as a residual classification for synthetic organic coloring matter and related preparations that do not fall under the more specific headings for fluorescent brightening agents or luminophores. It encompasses a broad range of synthetic organic dyes and pigments, including those that are chemically defined and those presented as preparations. These are typically used for imparting color to various materials such as textiles, plastics, paints, inks, and cosmetics. The key characteristic for classification here is their primary function as coloring agents derived from synthetic organic compounds.

This classification is distinguished from its sibling category, 3204.20, which specifically covers synthetic organic products used as fluorescent brightening agents. While both fall under the broader scope of synthetic organic coloring matter, 3204.20 is reserved for substances that enhance the perceived brightness of materials by absorbing ultraviolet light and emitting visible blue light, rather than simply imparting color. Therefore, if a synthetic organic product's primary function is to brighten and whiten, it would likely be classified under 3204.20, whereas if its primary function is to provide a specific hue or shade, it would fall under this "Other" category.

As this is a leaf node within the HTS structure, there are no further subcategories to introduce. Classification into 3204.90.00.00 hinges on the product being a synthetic organic coloring matter or a preparation thereof, and not qualifying for classification under any more specific heading within Chapter 32. Customs officers will examine the chemical composition, intended use, and the presence or absence of specific properties, such as fluorescence or luminescence, to determine if a product correctly falls into this residual category.
