CPC Subclass Not Allocatable
C05B PHOSPHATIC FERTILISERS
Description
C05B covers the manufacture and composition of fertilizers whose primary nutritive component is phosphorus or phosphate compounds. This includes superphosphates, triple superphosphates, phosphate rock products, and other phosphorus-containing fertilizer formulations, whether simple phosphate salts or complex mixtures with secondary nutrients. The classification encompasses both chemical processes for phosphate conversion and the resulting fertilizer products, but excludes nitrogen-phosphorus or potassium-phosphorus compound fertilizers, which fall under other C05 subclasses.

- C05B 1/00 Superphosphates, i.e. fertilisers produced by reacting rock or bone phosphates with sulfuric or phosphoric acid in such amounts and concentrations as to yield solid products directly
- C05B 11/00 Fertilisers produced by wet-treating or leaching raw materials either with acids in such amounts and concentrations as to yield solutions followed by neutralisation, or with alkaline lyes
- C05B 13/00 Fertilisers produced by pyrogenic processes from phosphatic materials
- C05B 15/00 Organic phosphatic fertilisers (bone meal C05B17/00)
- C05B 17/00 Other phosphatic fertilisers, e.g. soft rock phosphates, bone meal
- C05B 19/00 Granulation or pelletisation of phosphatic fertilisers, other than slag (granulating apparatus B01J2/00; granulating slag C04B)
- C05B 3/00 Fertilisers based essentially on di-calcium phosphate (C05B11/00 takes precedence)
- C05B 5/00 Thomas phosphate; Other slag phosphates
- C05B 7/00 Fertilisers based essentially on alkali or ammonium orthophosphates (C05B11/00 takes precedence)
- C05B 9/00 Fertilisers based essentially on phosphates or double phosphates of magnesium (C05B11/00 takes precedence)
