This applies to biocidal active substance/product type combinations which expire between 1 January 2024 and 31 December 2026 The active substance/product type combinations are able to be postponed providing a timely renewal application has been submitted and accepted. HSE provided information about the decision to postpone expiry dates in a previous ebulletin. The requirements have now been met for the active substance/product type combinations: From 30 April 2026 to 31 January 2027 - 3-phenoxybenzyl (1RS,3RS;1RS,3SR)-3-(2,2-dichlorovinyl)-2,2-dimethylcyclopropanecarboxylate (permethrin) (CAS 52645-53-1 EC 258-067-9) in product types 8 and 18
If you want to supply new biocidal products containing this active substance, you can still apply for GB BPR product authorisation. New products (including new trade names) must not be supplied in GB until product authorisation is granted. HSE will provide separate updates on the renewal decisions and future expiry date postponements captured within this overall decision when relevant. |
