HSE Biocides ebulletin

Issued: 20 March 2023

This ebulletin contains information on regulating biocides in Northern Ireland (NI). 

The EU Biocidal Products Regulation (EU BPR) operates independently from the GB Biocidal Products Regulation (GB BPR), which applies in Great Britain.

Separate ebulletins containing information specific to regulating biocides in Great Britain are issued as appropriate.

Upcoming EU active substance renewal submission deadlines

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

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

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

• 4-bromo-2-(4-chlorophenyl)-5- (trifluoromethyl)-1H-pyrrole-3-carbonitrile (Tralopyril) (CAS 122454-29-9 EC n/a) in product type 21
  28 September 2023
  
  
• Nonanoic acid (Pelargonic acid) (CAS 112-05-0 EC 203-931-2) in product type 2
  29 March 2024

Any person, company or taskforce/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 a renewal application is not submitted for the above active substance/product type combinations under EU BPR, the approvals will expire. This means the active substances can no longer be used in biocidal products of the relevant product types in NI.

Once the approvals expire, the active substances can no longer be used in biocidal products of the relevant product types in NI.

If you hold an affected EU 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 effects that are likely to arise from the expiry of any of the active substance/product type combinations listed above, please contact us.
