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.

 C05B
PHOSPHATIC FERTILISERS

 C05C
NITROGENOUS FERTILISERS

 C05D
INORGANIC FERTILISERS NOT COVERED BY SUB-CLASSES C05B, C05C; FERTILISERS PRODUCING CARBON DIOXIDE

 C05F
ORGANIC FERTILISERS NOT COVERED BY SUB-CLASSES C05B, C05C, e.g. FERTILISERS FROM WASTE OR REFUSE

 C05G
MIXTURES OF FERTILISERS BELONGING INDIVIDUALLY TO DIFFERENT SUB-CLASSES OF CLASS C05; MIXTURES OF ONE OR MORE FERTILISERS WITH MATERIALS NOT HAVING A SPECIFICALLY FERTILISING ACTIVITY, e.g. PESTICIDES, SOIL CONDITIONERS, WETTING AGENTS (organic fertilisers containing added bacterial cultures, mycelia, or the like C05F 11/08; organic fertilisers containing plant vitamins or hormones C05F 11/00)
