Note(s)

  1. A non-metallic single substance and/or its manufacture must be primarily classified in the place appropriate to the chemical nature of the substance, e.g. in C01, C07, C08.
  2. A particular chemical process (e.g. manufacture of a polyamide or polyester, the curing of an epoxy resin or of an aminoplast; the polymerisation of substances containing carbon-to-carbon unsaturation, or hydrogenation of a specific substance or narrow class of substances) characterised by the use of a particular catalyst is classified primarily with the process, by in the case of the use of a particular material as a catalyst in general, i.e. in chemical reactions applicable to a number of different types of starting material (examples are hydrogenation or esterification in general, or the Fischer-Tropsch reaction), the primary classification must be in the present group.
