  • Noble gases: He, Ne, Ar, Kr, Xe, Rn
  • Platinum group: Os, Ir, Pt, Ru, Rh, Pd
  • Noble metals: Ag, Au, Platinum group
  • Light metals: alkali metals, alkaline earth metals, Be, Al, Mg
  • Heavy metals: metals other than light metals

CHEMISTRY
 C05
FERTILISERS; MANUFACTURE THEREOF (processes or devices for granulating materials, in general B01J 2/00; soil-conditioning or soil-stabilising materials, e.g. mulches, C09K 17/00)  [4]
 C05

Note(s)

  1. An ingredient in a mixture of fertilisers, or a single fertiliser which contains more than one of the chemical elements on which the subdivision into subclasses is based, is classified only in the first of the appropriate subclasses. Thus, a nitrophosphate or an ammoniated superphosphate is classified in C05B but not in C05C, magnesium phosphate is classified in C05B but not in C05D, and calcium cyanamide in C05C but not in C05D.
  2. In this class, it is desirable to add, in conformity with paragraph 83 of the Guide, after the double oblique stroke, the indexing codes representing additional information which relates to individual constituents of a technical subject which is already classified as such. This additional information concerns the indication of ingredients of a mixture of different fertilisers or of fertilisers with non-fertilisers. The indexing codes have the same numbers as the classification symbols but a colon is used instead of the oblique stroke. These indexing codes should be presented as linked to the classification symbols with which they are associated, in conformity with paragraph 85 (a) of the Guide.
