As part of the EU Biocidal Products Regulation (EU BPR), active substance approvals must be renewed before their expiry date to continue being used in biocidal products. The European Chemicals Agency (ECHA) mandates that renewal applications be submitted at least 550 days before the expiry date. To avoid disruptions and ensure continued market access in Northern Ireland (NI), it is crucial to meet these upcoming deadlines.

Failure to submit a timely renewal application for the active substances listed above will result in the expiration of approvals. This means the substances cannot be used in biocidal products within the relevant product types in NI. Additionally, any products treated with these substances will be prohibited from being placed on the market in Northern Ireland.
