Chemical diversion

Vendors of precursor chemicals must submit an End user statement to the Chemical Diversion Desk each time regulated chemicals are sold.

This is required under the Controlled Substances Act (1984).

NOTE: Effective 1 July 2018 variations to the Controlled Substances Act (Poisons) Regulations 2011 will take effect. The variations will include 31 additional chemicals. The End user declaration is currently being reviewed. Please use the form available from the link below in the interim. Further information and updates will be provided in the coming months.
