Apply for active substance renewal by the relevant deadline to keep products on the GB market.
Under the GB Biocidal Products Regulation (GB BPR), active substance approvals will expire unless a renewal application is submitted to HSE at least 550 days before their expiry date.
The 550-day deadlines are coming up for the following active substance/product type combinations under GB BPR:
28 December 2026
- 2-(2-butoxyethoxy)ethyl 6-propylpiperonyl ether (piperonyl butoxide/PBO) (CAS 51-03-6 EC 200-076-7) in product type 18
- 2-methyl-1,2-benzothiazol-3(2H)-one (MBIT) (CAS 2527-66-4 EC 695-989-4) in product type 6
28 September 2027
- 2-methyl-2H-isothiazol-3-one (MIT) (CAS 2682-20-4 EC 220-239-6) in product type 12
- margosa extract from cold-pressed oil of Azadirachata indica seeds without shells extracted with super-critical carbon dioxide (CAS 84696-25-3 EC 283-644-7) in product type 19
Any person, company or task force/consortium can support an active substance/product type combination for renewal – it doesn’t have to be the original supporter.
Check the GB Article 95 List to see who the original supporters were.
If any of these active substance/product type combinations are important to you, consider contacting your supplier to let them know.
If a renewal application is not submitted for the above active substance/product type combinations under GB BPR, the approvals will expire. This means the active substances will no longer be able to be used in biocidal products of the relevant product types in GB.
In addition, articles treated with such products will no longer be able to be placed on the market in GB.
Biocidal products must be phased off the GB market.
The active substance/product type combinations listed are due to expire under GB BPR on the following dates:
30 September 2027
- peracetic acid (CAS 79-21-0 EC 201-186-8) in product types 1 and 6
31 December 2027
- amines, N-C10-16-alkyltrimethylenedi-, reaction products with chloroacetic acid (Ampholyt 20) (CAS 139734-65-9 EC 701-317-3) in product types 2, 3, and 4
- 2-bromo-2-(bromomethyl)pentanedinitrile (DBDCB) (CAS 35691-65-7 EC 252-681-0) in product type 6
- Bacillus amyloliquefaciens strain ISB06 (CAS N/A EC N/A) in product type 3
- N-(dichlorofluoromethylthio)-N′,N′-dimethyl-N-p-tolylsulfamide (tolylfluanid) (CAS 731-27-1 EC 211-986-9) in product type 7
Once the approvals expire, the active substances will no longer be able to be used in biocidal products of the relevant product types in GB.
In addition, articles treated with such products will no longer be able to be placed on the market in GB.
If you hold an affected GB BPR product authorisation or Control of Pesticides Regulations (COPR) product approval, we will contact you about cancelling or revoking your authorisation or approval. You will have an opportunity to submit comments or additional information and we will take account of these when finalising our decision.
If you are aware of any disproportionate negative impacts that are likely to arise from the expiry of the active substance/product type combinations listed, please contact us.
Stakeholders should note that biocides are in scope of the Sanitary and Phytosanitary (SPS) Agreement currently being negotiated between the UK and the EU. Once negotiations on the SPS Agreement have concluded, HSE will communicate further on any implications the Agreement has for the sector.
