Ilford Ilfocolor Unsensitized Paper Emulsion
Ilford's Ilfocolor unsensitized emulsion contains precisely balanced red, green, and blue-sensitive silver halide microcrystals suspended in photographic gelatin for coating color negative paper. It qualifies for HTS 3707.90.32.10 as a specialized chemical preparation for photographic uses, not covering waste and focused on color negative paper applications. Post-coating sensitization enables radiation-formed visible images.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If for use in black and white negative photographic paper
Monochromatic emulsions lack color coupler chemistry, classified separately from color emulsions.
If containing additives making it a chemical mixture beyond pure emulsion
Complex preparations with non-photographic chemicals may fall under general chemical mixtures in Chapter 38.
If in bulk form for direct plate-making rather than paper coating
Emulsions for lithographic printing plates have different grain and stability specs under sensitized preparations.
