EU active substance expiry dates postponed

Active substance expiry dates postponed whilst the renewal evaluation is completed in the EU

For reasons beyond the control of the applicants, the approvals of the active substance/product type combinations listed below were likely to expire before a decision could be taken on their renewal under the EU Biocidal Products Regulation (EU BPR).

To allow sufficient time for the renewal evaluation to be completed, a decision has been taken to postpone the expiry dates of the following approvals. This affects NI:

• 2,3,5,6-tetrafluoro-4-(methoxymethyl)benzyl (EZ)-(1RS,3RS;1SR,3SR)- 2,2-dimethyl-3-prop-1-enylcyclopropanecarboxylate (metofluthrin) (CAS 240494-71-7 EC N/A) in product type 18
  31 October 2024 to 30 April 2026
  
  
• Dinotefuran (CAS 165252-70-0 EC N/A) in product type 18
  30 November 2024 to 30 November 2025
  
  
• 4-phenoxyphenyl (RS)-2-(2- pyridyloxy)propyl ether (Pyriproxyfen) (CAS 95737-68-1 EC 429-800-1) in product type 18
  31 January 2025 to 31 July 2027
  
  
• Alkyl (C12-16) dimethylbenzyl ammonium chloride (ADBAC/BKC (C12-16)) (CAS 68424-85-1 EC 270-325-2) in product type 8
  31 January 2025 to 31 July 2027
  
  
• Formaldehyde (CAS 50-00-0 EC 200-001-8) in product types 2 and 3
  31 January 2025 to 31 July 2027
  
  
• N,N-Didecyl-N,N-dimethylammonium chloride (Didecyldimethylammonium chloride) (DDAC) (CAS 7173-51-5 EC 230-525-2) in product type 8
  31 January 2025 to 31 July 2027

If you want to supply new biocidal products containing these active substances, you can still apply for EU BPR product authorisation. New products (including new trade names) must not be supplied in NI until product authorisation is granted.

HSE will provide separate updates on the renewal decisions when relevant.

Upcoming EU active substance renewal submission deadline

Apply for active substance renewal by the deadline to keep products on the NI market

Under the EU BPR, active substance approvals will expire unless a renewal application is submitted to ECHA at least 550 days before their expiry date.

The 550-day deadline is coming up for the following active substance/product type combinations under EU BPR. This affects NI:

29 April 2025

• Polyhexamethylene biguanide hydrochloride with a mean number-average molecular weight (Mn) of 1415 and a mean polydispersity (PDI) of 4.7 (PHMB (1415;4.7)) (CAS 1802181-67-4 / 32289-58-0 EC N/A) in product types 2 and 4

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 EU Article 95 List to see who the original supporters were.

If 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 EU BPR, the approval will expire. This means the active substance will no longer be able to be used in biocidal products of the relevant product types in NI.

In addition articles treated with such products will no longer be able to be placed on the market in NI.
