BJ Sheriff have recently been contacted by the Home Office Chemical Reporting Team, who deliver parts of the Government’s Counter Terrorism Strategy, to request assistance in getting important information about Oxalic Acid (OA) out to the bee keeping industry. Oxalic Acid is a regulated poison under the 1972 Poisons Act. Generic OA, liquid and powder solutions including oxalic acid dihydrate and oxalic acid crystals, come under these restrictions when they are above the 10% concentration threshold.
All authorised Varroa treatments containing OA are exempt from restrictions and can continue to be bought by hobby beekeepers from the usual suppliers.
UK licenced products:
· API-Bioxal
· Dany’s BienenWohl Powder and Solution
· Oxuvar
· Oxybee
Substances not on the database that are prescribed by a vet through the cascade system (www.gov.uk/guidance/the-cascade-prescribing-unauthorised-medicines) are also exempt from the regulations.
Outside of the specified products, members of the public who want to import, acquire, possess, or use the regulated chemicals must hold an Explosives Precursors and Poisons (EPP) licence issued by the Home Office. From 1 October 2023 businesses supplying regulated explosives precursors or poisons to professional users and other businesses (those who don’t need a licence) need to be compliant and take additional steps to verify the legitimacy of the professional user or business.
To sell oxalic acid above 10% w/w concentration to a member of the public, in addition to them having an EPP license you must be lawfully conducting a retail pharmacy business, the supply must be made on a premises registered as a pharmacy and the sale must be under the supervision of a pharmacist.

For disposal of generic OA, licenced OA or other VMD licenced products the Home Office recommends contacting your local council for guidance.
