HS Code 2927
Diazo, Azo and Azoxy Compounds
HS code 2927 covers diazo-, azo-, or azoxy-compounds, which contain double nitrogen bonds and are primarily utilised as precursors for synthetic dyes and pigmen
HS Code 2927 — Diazo, Azo and Azoxy Compounds
This code covers organic compounds containing nitrogen-to-nitrogen double bonds. These chemicals are the primary building blocks for synthetic dyes and pigments used in the textile, leather, and printing industries, as well as specialised biochemical reagents.
What's included
- Azobenzene
- p-Aminoazobenzene
- Diazoaminobenzene
- Azoxyanisole
What's excluded
- Finished azo dyes → use
3204(Synthetic organic colouring matters are classified by their application as dyes rather than basic chemicals.)
Common examples
- 4-Aminoazobenzene-4-sulphonic acid
- Diazoacetic ester
- Azodicarbonamide blowing agent
Frequently asked questions
Are all azo compounds used for dyes?
While most are precursors to pigments, some function as indicators in laboratory testing or as blowing agents in plastics manufacturing.
