 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 sub-classes is based, is classified only in the first of the appropriate sub-classes. 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 80 of the Guide, after the double oblique stroke the symbols relating to complementary information concerning individual constituents of a technical subject which is already classified as such. This complementary information concerns the indication of ingredients of a mixture of different fertilisers or of fertilisers with non-fertilisers.
