Diazo-, azo- or azoxy-compounds
8 declarable lines
Heading 2927 covers diazo, azo, and azoxy compounds. It has lines for specific named compounds and residual lines for photographic chemicals, fast color bases and salts, section VI note 3 products, and other compounds.
Products in this heading
- 4-Aminoazobenzenedisulfonic acid, monosodium salt, a dye intermediate (2927.00.03.00)
- p-Aminoazobenzenedisulfonic acid, a dye intermediate (2927.00.06.00)
- Diazoaminobenzene (1,3-Diphenyltriazene) (2927.00.06.00)
- 1,1'-Azobisformamide, a blowing agent (2927.00.15.00)
- Diazo photographic chemicals (2927.00.25.00)
- Fast color bases and fast color salts for dyes (2927.00.30.00)
- Azo compounds not named in earlier lines (2927.00.50.00)
How to choose the right subheading
- Confirm the compound is a diazo, azo, or azoxy compound rather than another nitrogen-function compound.
- Check whether the chemical name matches one of the specific named lines in 2927.00.03.00, 2927.00.06.00, 2927.00.15.00, or 2927.00.18.00.
- For other diazo, azo, or azoxy compounds, check whether the use is as a photographic chemical for 2927.00.25.00.
- Check whether the product is a fast color base or fast color salt for 2927.00.30.00.
- Check whether additional U.S. note 3 to section VI applies for 2927.00.40.00; if none of these apply, use 2927.00.50.00.
Often confused with
- Heading 3204Prepared azo dye mixtures
Dye preparations and mixtures are classified as synthetic organic colouring matter, not as separate chemically defined azo compounds.
- Heading 2921Aniline
Aniline is an amine-function compound, not a diazo, azo, or azoxy compound.
- Heading 2928Phenylhydrazine
Hydrazine derivatives are classified in heading 2928, not as diazo compounds.
- Heading 2935Sulfanilamide
Sulfonamides are classified in heading 2935 even when they contain an amino group.
