HTS US: 2927.00.XX.XX
Description
Heading 2927 covers a range of chemical compounds characterized by the presence of diazo, azo, or azoxy functional groups. These compounds are primarily used in various industrial applications including dyes, pigments, photographic chemicals, and specialized chemical manufacturing.
The compounds include:
- Diazo-compounds: Organic compounds containing the diazo group (-N=N-), often used as intermediates in dye manufacture.
- Azo-compounds: Compounds containing the azo group (-N=N-), widely used as colorants due to their vivid colors.
- Azoxy-compounds: Related compounds containing the azoxy group (-N=N(O)-), which have unique chemical properties for specialized applications.
