EU active substance expiry date postponed

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

For reasons beyond the control of the applicant, the approval of the active substance/product type combination listed below was likely to expire before a decision could be taken on its 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 of the approval until the following date. This affects Northern Ireland (NI):

  • 1-[[2-(2,4-dichlorophenyl)-4-propyl-1,3-dioxolan-2-yl]methyl]-1H-1,2,4-triazole (Propiconazole) (CAS 60207-90-1 EC 262-104-4) in product type 8 – 31 December 2023

If you want to supply new biocidal products containing this active substance, 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 a separate update on the renewal decision when relevant.

Manufacture of hand sanitiser products in the UK

Current arrangements for Article 95 compliance come to an end

In response to the pandemic, HSE took steps to assist industry’s efforts to increase the availability of hand sanitisers to help reduce the spread/transmission of COVID-19.

One of these steps was adopting a pragmatic and proportionate approach to the requirement for all biocidal products supplied in the UK to contain active substances sourced from suppliers on the Article 95 list.

Information gathered from a range of stakeholders suggests that hand sanitiser manufacturers are no longer experiencing any difficulties in sourcing their active substance from an Article 95 supplier.

This means that the proportionate approach to the Article 95 requirement, put in place at the beginning of the pandemic for hand sanitiser products, will be discontinued.

Accessing the UK market

Businesses wishing to supply hand sanitiser products must ensure that their active substance is sourced from a supplier on:

  • the GB Article 95 List, in Great Britain
  • the EU Article 95 List, in Northern Ireland

Alternatively, businesses may apply to get on the relevant Article 95 list themselves:

Background

Article 95 of the BPR aims to create a level playing field across industry by ensuring that all suppliers of biocidal products have paid a share of the cost of supporting the active substance dossier through an evaluation process.

The BPR requires either the supplier of the active substance used in a biocidal product, or the supplier of that biocidal product, to be included on the Article 95 list for the relevant active substance / product type combination.

This requirement applies to all biocidal products made available on the UK market, including:

  • products authorised under the BPR
  • products in the process of getting a BPR authorisation
  • products regulated under other national legislation in the UK, such as the Control of Pesticides Regulations (COPR)
  • products where the active substance / product type combination is still being reviewed e.g. ethanol

To aid the rapid supply of hand sanitiser products, HSE adopted a pragmatic and proportionate approach to these regulatory requirements, focussing on ensuring that high levels of safety and efficacy of hand sanitiser products were maintained.

As part of the approach, HSE expected product manufacturers to have taken all reasonable steps to comply with Article 95 obligations. At all times, manufacturers were expected to continue to be mindful of maintaining high levels of safety and efficacy of the products they were making available to the public and others.

Biocidal products must be phased off the NI market

The active substance/product type combination listed below is due to expire under the EU Biocidal Products Regulation (EU BPR) on the following date. This affects Northern Ireland (NI):

  • (±)-5-amino-1-(2,6- dichloro-α,α,α,- trifluoro-p-tolyl)-4- trifluoromethylsulfinylpyrazole-3-carbonitrile (1:1) (Fipronil) (CAS 120068-37-3 EC 424-610-5) in product type 18 – 30 September 2023

Once the approval expires, the active substance can no longer be used in biocidal products of the relevant product type in Northern Ireland.

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 expiry of any of the active substance/product type combinations listed above, please contact HSE (GB).

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 Northern Ireland.

Open invitation to notify Glucoprotamin for product-type 2 and 4

Notify ECHA by 4 August 2023 to keep this substance in the Review Programme.

The following deadlines are listed to help companies to comply with their obligations under the Biocidal Products Regulation (BPR) and the Review Programme Regulation (RPR):

Now available: European Chemicals Agency (ECHA) opinions on companies’ requests to classify changes to their biocidal product authorisations

Companies can make changes to their authorised biocidal products by either notifying the authorities or by submitting an application. The process depends on the level of change the company would like to make to the existing authorisation: administrative, minor or major. Various change types are listed in the annex of the European Commission’s Implementing Regulation on changes of authorised biocidal products (No 345/2013).

If the foreseen change is not listed in the annex, a company has the possibility to request ECHA’s opinion on the classification of the change. The classification will help companies understand which type of application they should submit to change their biocidal product authorisations.

Recommendations on preparing a summary of product characteristics

The European Chemicals Agency (ECHA) has published recommendations on preparing a Summary of Product Characteristics (SPC) for biocidal products and biocidal product families.

They were developed to help applicants and Member State competent authorities prepare a clear and comprehensible SPC which follows the requirements of the Biocidal Products Regulation (BPR).

The document compiles agreements from the Coordination Group, Biocides competent authority meetings and Biocidal Products Committee meetings and is applicable to single products and biocidal product families.
