HSE Biocides ebulletin

Issued: 15 January 2024

This ebulletin contains information on regulating biocides in Great Britain (GB). 

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

Separate ebulletins containing information specific to regulating biocides in Northern Ireland are issued as appropriate.

Upcoming GB active substance open invitation deadline

Submit a notification by the deadline to keep active substances in the GB Review Programme

HSE has published an open invitation (.pdf) to provide an opportunity for a person, company or task force/consortium to notify an intention to take up or take over the role of participant in the GB Review Programme for the following active substance/product type combination.

Anyone wishing to support the active substance/product type combination listed below in GB will need to submit a notification to HSE by the following deadline:

• Peanut butter (CAS n/a EC n/a) in product type 19
  14 March 2024
  

If a notification to take over the role of participant is not received, this active substance/product type combination will be subject to a GB non-approval decision. Biocidal products and treated articles containing active substances with GB non-approval decisions for the relevant product types will have to be removed from the GB market.

HSE will provide separate updates on these where relevant.

If you are aware of any disproportionate negative impacts that are likely to arise from the non-approval of the active substance/product type combination listed above, please contact us.

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