| SECTION C – CHEMISTRY; METALLURGY |
|
| C 05 | FERTILISERS; MANUFACTURE THEREOF (processes or devices for granulating materials, in general B01J 2/00; soil-conditioning or soil-stabilising materials C09K 17/00) [4] |
|
| 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 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 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 C05B 1/10 and C05B 11/02, C05C 1/02 and C05C 7/02, C05F 1/02, C05F 3/06, C05F 9/02, C05F 11/06 and C05F 17/02, have the same numbers as the classification symbols, but a colon is used instead of the oblique stroke, and should be linked. |

| C 05 B | PHOSPHATIC FERTILISERS |
|
| C 05 C | NITROGENOUS FERTILISERS |
|
| C 05 D | INORGANIC FERTILISERS NOT COVERED BY SUBCLASSES C05B, C05C; FERTILISERS PRODUCING CARBON DIOXIDE |
|
| C 05 F | ORGANIC FERTILISERS NOT COVERED BY SUBCLASSES C05B, C05C, e.g. FERTILISERS FROM WASTE OR REFUSE |
|
| C 05 G | MIXTURES OF FERTILISERS COVERED INDIVIDUALLY BY DIFFERENT SUBCLASSES OF CLASS C05; MIXTURES OF ONE OR MORE FERTILISERS WITH MATERIALS NOT HAVING A SPECIFIC 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 11/10); FERTILISERS CHARACTERISED BY THEIR FORM [4] |
