| Notes |
|
| (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 C 05 B but not in C 05 C, magnesium phosphate is classified in C 05 B but not in C 05 D, and calcium cyanamide in C 05 C but not in C 05 D. |
|
| (2) | In this class, it is desirable to add the indexing codes relating to ingredients of a mixture of different fertilisers or of fertilisers with non-fertilisers. The indexing codes, which are chosen from the groups in this class, with the exception of groups C 05 B 1/10 and C 05 B 11/02, C 05 C 1/02 and C 05 C 7/02, C 05 F 1/02, C 05 F 3/06, C 05 F 9/02, C 05 F 11/06 and C 05 F 17/02, have the same numbers as the classification symbols, but a colon is used instead of the oblique stroke, and should be linked. |
