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

Upcoming EU active substance dossier submission deadline

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 an open invitation.

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

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 the 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 substance 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 renewal submission deadlines

Apply for active substance renewal by the relevant deadline to keep products on the NI market.

Under the EU Biocidal Products Regulation (EU BPR), active substance approvals will expire unless a renewal application is submitted to ECHA at least 550 days before their expiry date.

The 550-day deadlines are coming up for the following active substance/product type combinations under EU BPR. This affects NI:

30 April 2027

  • pyrogenic, synthetic amorphous, nano, surface treated silicon dioxide (CAS 68909-20-6 EC 272-697-1) in product type 18
  • silicon dioxide kieselguhr (CAS 61790-53-2 EC 612-383-7) in product type 18

28 October 2027

  • L-(+)-lactic acid (CAS 79-33-4 EC 201-196-2) in product types 2, 3 and 4
  • propan-1-ol (CAS 71-23-8 EC 200-746-9) in product types 1, 2 and 4

29 April 2028

  • creosote (CAS 8001-58-9 EC 232-287-5) in product type 8


Any person, company or task force/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 any of these active substance/product type combinations are important to you, consider contacting your supplier to let them know.

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 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.

Stakeholders should note that biocides are in scope of the Sanitary and Phytosanitary (SPS) Agreement currently being negotiated between the UK and the EU. Once negotiations on the SPS Agreement have concluded, HSE will communicate further on any implications the Agreement has for the sector.

Discover the safety climate tool

Created by HSE experts, the safety climate tool (SCT) explores your workers’ attitudes and perceptions in key areas of health and safety, while guaranteeing anonymity.

It measures an element of safety culture – the ‘way things are done’ in your organisation. The results can help you identify areas for improvement and raise health and safety standards.
