If its intended function is to destroy, deter, or control harmful organisms — bacteria, viruses, fungi, pests — by chemical or biological means, then yes, it is treated as a biocidal product regardless of how it is marketed, and needs authorisation under the GB biocides framework. ### Do I need a UKCA mark for a biocidal product? No. Biocidal products are authorised through the biocides-specific regime rather than CE/UKCA-style conformity marking. Authorisation and marking are separate frameworks that apply to different categories of regulated product. ### Does an EU biocidal product authorisation automatically cover Great Britain? Not automatically. GB and EU biocides frameworks diverged after Brexit; an authorisation that existed at the point of transition may have carried over under transitional arrangements, but new authorisations are generally assessed separately for GB. ### What is the difference between active substance approval and product authorisation? Active substance approval confirms that a specific chemical active ingredient is acceptable for use in a given product type. Product authorisation is the separate, subsequent step that approves a specific formulated product — built from approved active substances — for sale with defined claims and use instructions. **Disclaimer:** This page is an educational resource only and does not constitute legal advice.
