Reminder - upcoming EU active substance expiry dates

Biocidal products must be phased off the NI market

The active substance/product type combinations listed below are due to expire under the EU BPR on the following dates. This affects NI:

  • Margosa extract from the kernels of Azadirachata Indica extracted with water and further processed with organic solvents (CAS 84696-25-3 EC 283-644-7) in product type 18
    30 April 2024

  • Undecan-2-one (methyl nonyl ketone) (CAS 112-12-9 EC 203-937-5) in product type 19
    30 April 2024

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

If you hold an affected EU 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 effects that are likely to arise from the non-approval of any of the active substance/product type combinations listed above, please contact us.


New EU active substance non-approval decision

Biocidal products must be phased off the NI market

Following evaluation/withdrawal of support under the EU BPR, a decision has been taken not to approve the following active substance/product type combination. This will affect NI:

Biocidal products containing this active substance in the relevant product type can no longer be:

  • supplied in NI after 26 March 2024; or
  • used in NI after 26 September 2024

You must manage your stocks of the affected products to ensure they are removed from the NI supply chain by 26 March 2024.

New treated articles containing this active substance in the relevant product type cannot enter the supply chain or be imported into NI after 22 September 2024. Treated articles that have entered NI supply chains before this date can continue to be supplied and used. Find out more about treated articles.

Any affected NI product approvals under the COPR will be revoked in line with the above dates.

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 below were likely to expire before a decision could be taken on their renewal under the EU BPR.

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


Active substances no longer supported in the EU

Non-approval decision to be taken for unsupported active substance in the EU

Following an opportunity for any person, company or taskforce/consortium to support the active substance/product type combinations listed below in the EU Review Programme, no compliant notifications were received. This affects NI:

  • Potassium dimethyldithiocarbamate (CAS 128-03-0 EC 204-875-1) in product types 9, 11 and 12

This active substance/product type combination will now be subject to an EU non-approval decision.

Once a decision is taken, biocidal products containing this active substance in the relevant product types will have to be removed from the NI market. HSE will provide separate updates on the decision and relevant phase-out periods.

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