UK Declares Non-Approval for 63 Active Substances in Biocidal Products Regulations
Manufacturers, suppliers, and users are urged to review the list and prepare for the upcoming changes to ensure compliance.


The Health and Safety Executive (HSE) has issued an urgent notice regarding the regulation of biocides within Great Britain. This notice includes essential deadlines for the renewal of active substances under the GB Biocidal Products Regulation (GB BPR), distinct from the EU counterpart. The notice also addresses an upcoming non-approval decision for a specific active substance.
To ensure continued market presence, stakeholders must submit renewal applications for active substances 550 days before their current approval expires. The upcoming deadlines are pivotal for several active substances across various product types, specifically:
29 June 2024, Deadlines for Product Type 21:4,5-Dichloro-2-octyl-2H-isothiazol-3-one (DCOIT) (CAS 64359-81-5 EC 264-843-8)Bis(1-hydroxy-1H-pyridine-2-thionato-O,S)copper (Copper pyrithione) (CAS 14915-37-8 EC 238-984-0)Copper flakes (coated with aliphatic acids) (CAS 7440-50-8 EC 231-159-6)Copper thiocyanate (CAS 1111-67-7 EC 214-183-1)Dichloro-N-[(dimethylamino)sulphonyl] fluoro-N-(ptolyl)methanesulphenamide (Tolylfluanid) (CAS 731-27-1 EC 211-986-9)Dicopper oxide (CAS 1317-39-1 EC 215-270-7)N-(dichlorofluoromethylthio)-N′,N′-dimethyl-N-phenylsulfamide (Dichlofluanid) (CAS 1085-98-9 EC 214-118-7)Zinc ethylenebis(dithiocarbamate) (polymeric) (Zineb) (CAS 12122-67-7 EC 235-180-1)29 June 2024, Deadlines for Other Product Types:N-(trichloromethylthio)phthalimide (Folpet) in Product Types 6 (CAS 133-07-3 EC 205-088-6)Pythium oligandrum, Chromista - Stramenopila in Product Type 1029 March 2025, Deadlines:(E)-1-(2-chloro-1,3-thiazol-5-ylmethyl)-3-methyl-2-nitroguanidine (Clothianidin) in Product Type 18 (CAS 210880-92-5 EC 433-460-1)2-methyl-2H-isothiazol-3-one (MIT) in Product Type 13 (CAS 2682-20-4 EC 220-239-6)Glutaral (Glutaraldehyde) in Product Types 2, 3, 4, 6, 11, and 12 (CAS 111-30-8 EC 203-856-5)N-(trichloromethylthio)phthalimide (Folpet) in Product Types 7 and 9 (CAS 133-07-3 EC 205-088-6)
Silver nitrate (CAS 7761-88-8 EC 231-853-9) in Product Type 1 is facing a non-approval decision due to a lack of compliant support within the GB Review Programme. This decision will prevent its use in biocidal products and the marketing of articles treated with such products in Great Britain.
The HSE is open to feedback regarding potential negative impacts of the non-approval decisions and encourages stakeholders to reach out by 20 April 2024.
