Heading 2921
Amine-function compounds
76 declarable lines
Heading 2921 covers amine-function compounds. It is split first by structure into acyclic monoamines, acyclic polyamines, cyclanic, cyclenic or cycloterpenic amines, aromatic monoamines and aromatic polyamines, then by named compounds or Other lines.
Products in this heading
- Methylamine and dimethylamine
- Ethylenediamine
- Hexamethylenediamine
- Aniline
- N,N-Dimethylaniline
- Diphenylamine
- Toluene-2,4-diamine
How to choose the right subheading
- Check whether the amine is acyclic or cyclic, including cyclanic, cyclenic, cycloterpenic or aromatic.
- Separate monoamines from polyamines within the acyclic, aromatic and other structural groups.
- Check for a specific named compound line before using an Other line.
- Confirm whether the item is the amine itself, a salt, or a derivative, because the heading includes derivatives and salts.
- For aromatic compounds, decide whether the product is an aromatic monoamine or an aromatic polyamine.
Often confused with
- Heading 2923Quaternary ammonium salts

- Heading 2922Amino acids
Contain an oxygen function in addition to the amine function.
- Heading 2924Acetamide
Amide-function compound, not an amine-function compound.
- Heading 2926Acrylonitrile
Nitrile-function compound, not an amine-function compound.
- Heading 2930Thiourea
Organo-sulfur compound, not an amine-function compound.
