C05B PHOSPHATIC FERTILISERS
Introduced: September 1968
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.
Of 11 combined children, 10 exist in both systems.
1 codes exist only in IPC.
5 shared codes have differing titles between IPC and CPC.
