Products classified under HTS 2927.00.25.00
4-Diazo-2,5-Dibutoxyphenyl Morpholine
This diazo compound serves as a key coupling component in color photographic film development, forming azo dyes upon reaction with couplers. It falls under HTS 2927.00.25.00 as a diazo-type photographic chemical used specifically in photosensitive materials for imaging processes.
2-Diazo-1-Naphthol-4-Sulfonic Acid
A diazo coupling agent used in diazo-type copying papers and films, reacting to produce visible azo images upon light exposure. Classified under HTS 2927.00.25.00 due to its role in light-sensitive photographic reproduction processes.
Fast Red Salt RC Diazo Compound
Commercial diazo salt formulation for high-speed photographic coupler reactions in color print materials. HTS 2927.00.25.00 applies to this photographic chemical due to its specialized use in image-forming azo dye processes.
p-Diazo-N,N-Dimethylaniline Zinc Chloride
Stabilized double salt used in instant photographic developers for rapid azo coupling in print materials. Falls under HTS 2927.00.25.00 as a photographic diazo compound per Chapter 29 coordination compound rules.
Diazo Blue RC Stabilized Salt
Photographic diazo coupler producing blue azo dyes in multilayer color films during development. HTS 2927.00.25.00 classification reflects its exclusive use in photosensitive imaging chemistry.
3,3'-Dimethoxybiphenyl-4,4'-Diazonium Salt
Complex diazo compound for high-resolution photographic printing plates and films. Classified in HTS 2927.00.25.00 for its function in light-activated azo imaging chemistry.
Tetrazolium Blue Chloride
Diazo-tetrazolium salt used in photographic redox imaging and viability staining for film quality control. HTS 2927.00.25.00 covers this as a photographic chemical despite dual lab uses.
