Upcoming GB Deadlines for Biocides Dossier and Active Substance Renewals

Key Dossier Submission Deadlines

The following active substance and product type combinations require dossier submissions to the HSE by the given deadlines to remain approved for use in Great Britain (GB):

• 5 January 2025: N-didecyl-N-dipolyethoxyammonium borate (product type 8)
• 17 April 2025: Active chlorine generated from sodium chloride by electrolysis (product types 2, 3, 4, 5, and 11)

Failure to submit dossiers by these dates will result in a GB non-approval decision. This would restrict the use of these substances in biocidal products and prevent treated articles from being placed on the GB market​.

Active Substance Renewal Deadlines

To keep certain active substances approved under the GB Biocidal Products Regulation (GB BPR), renewal applications must be submitted 550 days before their expiry date. One notable upcoming renewal deadline is:

• 29 April 2025: Polyhexamethylene biguanide hydrochloride (PHMB) in product types 2 and 4.

If a renewal application is not submitted, these substances will no longer be usable in their respective product types​.‍

‍Companies or consortia that originally notified these substances must submit dossiers, though other parties may be able to support renewals. Those impacted by the loss of these approvals should contact the notifier or supplier to explore potential collaboration opportunities.

With critical submission deadlines approaching, stakeholders in the GB biocides industry must act swiftly to avoid market disruptions. Missing these deadlines could significantly affect product availability and compliance with GB regulations.
