EU active substance expiry dates postponed

Active substance expiry dates postponed whilst the renewal evaluation is completed in the EU.

For reasons beyond the control of the applicants, the approvals of the active substance/product type combinations listed were likely to expire before a decision could be taken on their renewal under the EU Biocidal Products Regulation (EU BPR).

To allow sufficient time for the renewal evaluation to be completed, a decision has been taken to postpone the expiry dates of the following approvals. This affects NI:

If you want to supply new biocidal products containing these active substances, you can still apply for EU BPR product authorisation. New products (including new trade names) must not be supplied in NI until product authorisation is granted.

HSE will provide separate updates on the renewal decisions when relevant.
