3707.90.60.00 - Unmixed products for photographic uses, put up in measured portions or put up for retail sale in a form ready for use

This HTS category, 3707.90.60.00, specifically addresses unmixed chemical products intended for photographic applications, provided they are prepared in a manner that makes them ready for immediate use. This typically includes individual components of photographic processes that are not compounded with other substances. The key characteristic is their presentation: they are either supplied in measured portions, ensuring a precise quantity for a specific photographic task, or are packaged for retail sale in a form that requires no further mixing or preparation by the end-user.

It is important to distinguish this category from its sibling, "Chemical preparations for photographic uses." While both relate to photographic chemicals, 3707.90.60.00 is reserved for *unmixed* products. The sibling category would encompass more complex mixtures or formulations that may have undergone further processing or blending to create a ready-to-use chemical preparation. This subcategory, therefore, focuses on the raw, individual chemical entities as they are presented for direct photographic application.

As this is a leaf node within the HTS, there are no further subcategories. Classification at this level relies on the definitive criteria of being an unmixed product intended for photographic use and presented in measured portions or for retail sale in a ready-to-use format. Examples include individual developing agents or fixing agents presented in pre-measured sachets or small, user-friendly containers designed for direct application without dilution or further treatment.
