Upcoming EU active substance dossier submission deadlines

Take action to keep your active substance in the EU Review Programme.

The active substance/product type combinations listed have been successfully notified into the EU Review Programme following open invitations.

The next step is for a full active substance dossier to be submitted to the European Chemicals Agency (ECHA) by the following deadlines. This affects NI:

16 April 2026

• hydrogen peroxide (CAS 7722-84-1 EC 231-765-0) in product type 11
  
  

8 January 2027

• chlorine dioxide generated from tetrachlorodecaoxide complex (TCDO) by acidification (CAS N/A EC N/A) in product types 2 and 4
  
  

Only the person, company or task force/consortium that successfully notified the active substance/product type combinations listed 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 ECHA list of notifications.

If a dossier is not submitted by the deadline, these active substance/product type combinations will be subject to an EU non-approval decision. This means the active substances will no longer be able to be used in biocidal products of the relevant product types in NI.

In addition articles treated with such products will no longer be able to be placed on the market in NI. HSE will provide separate updates on these where relevant.

Upcoming EU active substance expiry date

Biocidal products must be phased off the NI market.

The active substance/product type combinations listed are due to expire under the EU Biocidal Products Regulation (EU BPR) on the following date. This affects NI:

31 January 2027

• hydrogen peroxide (CAS 7722-84-1 EC 231-765-0) in product type 6
• N-((6-chloro-3-pyridinyl)methyl)-N′-cyano-N-methylethanimidamide (acetamiprid) (CAS 135410-20-7 EC 603-921-1) in product type 18
  
  

Once the approvals expire, the active substances will no longer be able to be used in biocidal products of the relevant product types in NI. In addition articles treated with such products will no longer be able to be placed on the market 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 impacts that are likely to arise from the expiry of the active substance/product type combinations listed, please contact us.
