3707.90.31.00 - Acid violet 19 🖩

This HTS classification covers specific chemical preparations designed for photographic uses, excluding broader categories like varnishes, glues, adhesives, and similar preparations. It specifically includes unmixed products intended for photographic processes that are presented in measured portions or in a ready-to-use retail form. Acid violet 19, as a specific dye or chemical agent utilized in photographic development or processing, falls under this designation.

The distinction between this subcategory and its sibling, 3707.90.32 (Other), lies in the precise nature of the chemical preparation. While 3707.90.32 would encompass a wider range of photographic chemical preparations not otherwise specified or classified, this particular category, 3707.90.31, focuses on a more defined set of individual chemical compounds or mixtures that are ready for direct application in photographic processes. The key differentiator is the specific composition and intended use as a photographic chemical in a ready-to-use format.

As this is a leaf node within the HTS, there are no further subcategories. Therefore, the classification concludes with the identification of specific products like Acid violet 19 that precisely fit the description of chemical preparations for photographic uses, presented in measured portions or retail-ready forms. Classification at this level relies on the accurate identification of the substance and its direct application within photographic activities.
