Amines are organic nitrogen compounds containing an amine functional group (that is, a group obtained from ammonia by replacing one, two or three hydrogen atoms with one, two or three alkyl or aryl radicals R (methyl, ethyl, phenyl, etc.), respectively). If only one hydrogen atom is substituted in ammonia, the primary amine (R·NH2) is obtained; the replacement of two hydrogen atoms gives a secondary amine (R-NH-R1); the replacement of three hydrogen atoms gives a tertiary amine

Nitrozoamines which may react in the tautomeric form of quinonymine oximes are classified in this heading. This heading also includes salts (e.g. nitrates, acetates, citrates) and substituted derivatives of amines (e.g. halogenated, sulfated, nitrated or nitrosed derivatives); however, this heading does not include substituted derivatives with oxygen-containing functional groups of headings 2905 to 2920 and their salts (heading 2922). This heading also excludes substituted derivatives in which one or more hydrogen atoms of an amine functional group are substituted by one or more halogen atoms, sulfo (-SO3H), nitro (-NO2) or nitrose (-NO) groups or any combination thereof. Diazotizing amines and their salts of this heading, diluted to standard concentrations for the preparation of azo dyes, are also classified in this heading.

(8) Diamistilbene. Certain substances in this heading which under international regulations are considered psychotropic substances are listed at the end of Chapter 29. Explanation of subheadings. Subheadings 2921 42 to 2921 49 Hydrocarbon derivatives of aromatic monoamine are derivatives obtained by replacing one or both amine nitrogen hydrogen atoms with an alkyl or cycloalkyl group only. Therefore, substituents with one or more aromatic nuclei, associated or not with amine nitrogen alkyl chain, are not included. Thus, for example, xylidine is to be classified in subheading 2921 49 as “other aromatic monoamines” and is not to be regarded as a derivative of aniline (subheading 2921 42) or toluidine (subheading 2921 43).

1. Within any one heading of this chapter, derivatives of a chemical compound (or group of chemical compounds) are to be classified in the same subheading as that compound (or group of compounds), provided that they are not more specifically covered by any other subheading and that there is no residual subheading named ‘Other’ in the series of subheadings concerned.
