Upcoming GB active substance expiry date

Biocidal products must be phased off the GB market

The active substance/product type combination listed below is due to expire under the GB BPR on the following date:

  • 4-bromo-2-(4-chlorophenyl)-1-ethoxymethyl-5-trifluoromethylpyrrole-3-carbonitrile (Chlorfenapyr) (CAS 122453-73-0 EC n/a) in product type 8
    30 April 2025

Once the approval expires, the active substance will no longer be able to be used in biocidal products of the relevant product type 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 any of the active substance/product type combinations listed above, please contact us.


Upcoming GB active substance dossier submission deadline

Take action to keep your active substance in the GB Review Programme

The active substance/product type combinations listed below have been successfully notified into the GB Review Programme following an open invitation. The next step is for a full active substance dossier to be submitted to HSE by the following deadline:

  • Active chlorine generated from sodium chloride by electrolysis (CAS 7782-50-5 EC n/a) in product types 2, 3, 4, 5 and 11
    17 April 2025

Only the person, company or task force/consortium that successfully notified the active substance/product type combinations listed above can submit a dossier. If any of these active substance/product type combinations are important to you, consider contacting the notifier to let them know. You may even be able to join them in supporting the active substance.

Check the list of successful notifiers

If a dossier is not submitted by the deadline, these active substance/product type combinations will be subject to a GB non-approval decision. This means the active substance 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. HSE will provide separate updates on these where relevant.


Active substance no longer supported in GB

Non-approval decision to be taken for unsupported active substances in GB

Following an opportunity for any person, company or task force/consortium to support the active substance/product type combination listed below in the GB Review Programme, no compliant notification or dossier was received:

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

In cases where active substance/product type combinations are not supported, GB biocides Regulations require that these active substance/product type combinations are subject to a GB non-approval decision.

Once a decision is taken, the active substance will no longer be able to be used in biocidal products of the relevant product type in GB.

In addition, articles treated with such products will no longer be able to be placed on the market in GB. HSE will provide separate updates on the decision and relevant phase-out periods.

Important: If you are aware of any disproportionate negative impacts that are likely to arise from the non-approval of any of the active substance/product type combinations listed above, please contact us by 30 May 2024
