MANUFACTURE OF FERTILISERS
 C05

Note(s)

An ingredient in a mixture of fertilisers, or a single fertiliser which contains more than one of the chemical elements on which the division 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.

When classifying a mixture of different fertilisers, or fertilisers with non-fertilisers the symbols appropriate to each separate ingredient of the mixture should be shown after the symbol appropriate to the mixture, in the manner indicated in para. 61 of the Guide. For example a mixture of Thomas phosphate with an organic phosphatic fertiliser would bear symbols C05B 21/00 // C05B 5/00, C05B 15/00; a mixture of Thomas phosphate sodium nitrate, and a potassium compound, the symbol C05G 1/04 // C05B 5/00; C05C 5/02; C05D 1/00; a mixture of organic phosphatic fertiliser with phenol (as a pesticide) the symbols C05G 3/02 // C05B 15/00; A01N 9/26; and a mixture of urea-formaldehyde fertilising condensate with a particular alkyl sulphonate as wetting agent, the symbols C05G 3/06 // C05C 9/02; B01F 17/02. Insignificant amounts, e.g. of impurities in a fertiliser, are disregarded.
