HSE Biocides ebulletin

Issued: 24 April 2023

This ebulletin contains information on regulating biocides in Northern Ireland (NI). 

The EU Biocidal Products Regulation (EU BPR) operates independently from the GB Biocidal Products Regulation (GB BPR), which applies in Great Britain.

Separate ebulletins containing information specific to regulating biocides in Great Britain are issued as appropriate.

Any person, company or taskforce/consortium can support an active substance/product type combination for renewal – it doesn’t have to be the original supporter. Check the EU Article 95 List to see who the original supporters were.

If a renewal application is not submitted for the above active substance/product type combinations under EU BPR, the approvals will expire. This means the active substances can no longer be used in biocidal products of the relevant product types in NI.

New EU active substance approval decision

Apply for product authorisation by the deadline to keep your products on the NI market

Following evaluation under the EU BPR, a decision has been taken to approve the following active substance/product type combination. This will affect NI:

• Alkyl (C12-16) dimethylbenzyl ammonium chloride (ADBAC/BKC (C12-16)) (CAS 68424-85-1 EC 270-325-2) in product type 1

Action for biocidal product suppliers

If you supply biocidal products containing this active substance in the relevant product type, you must apply for EU BPR product authorisation by 1 July 2024 to keep them on the NI market. New products (including new trade names) must not be supplied in NI until product authorisation is granted.

Action for active substance suppliers

If you supply this active substance for use in biocidal products of the relevant product type, you may need to apply for technical equivalence. If you haven’t demonstrated technical equivalence for your manufacturing source, EU BPR product authorisation cannot be granted for biocidal products containing your active substance.

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:

• 2,2-dibromo-2-cyanoacetamide (DBNPA) (CAS 10222-01-2 EC 233-539-7) in product type 4

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

• supplied in NI after 23 March 2024; or
  
  
• used in NI after 23 September 2024

You must manage your stocks of the affected products to ensure they are removed from the NI supply chain by 23 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 19 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 Control of Pesticides Regulations (COPR) will be revoked in line with the above dates.

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.
