Once the approvals expire, the active substances 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. 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.

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.
