NI implementation of EU Biocides Regulation and CLP under the Protocol: implications for UK health and safety compliance

What has changed

The Protocol on Ireland and Northern Ireland within the Withdrawal Agreement requires that EU legislation listed in Annex 2 to the Protocol is implemented in Northern Ireland. Annex 2 includes Regulation (EU) No 528/2012 concerning biocidal products and Regulation (EC) No 1272/2008 on classification, labelling and packaging of substances and mixtures. The 2026 amendment to Northern Ireland law therefore transposes these EU rules so that NI markets, suppliers and users are governed by the EU Biocides Regulation and CLP requirements in the NI context.

For organisations active in NI that supply, use or place biocidal products on the market or handle chemicals requiring classification and labelling, this change affects compliance duties, product information and safety communications across the supply chain.

Why this matters for UK health and safety and regulatory compliance

The move creates a harmonised baseline for chemical safety in Northern Ireland aligned with EU rules. It addresses cross border considerations for importers, manufacturers and distributors who operate in NI and may also deal with the Republic of Ireland or other EU markets. The change focuses attention on hazard communication, product authorisations and ongoing risk management for biocidal products and other regulated substances, with potential implications for safety data sheets, labelling, and supplier declarations.

What organisations should do next

Review current authorisations, product classifications and labelling to ensure they meet the EU Biocides Regulation and CLP requirements as implemented in NI. Update safety data sheets and packaging to reflect NI compliant labelling. Confirm supply chain responsibilities and ensure contractors and onboarding processes align with the new NI obligations. Engage with competent advisory support as needed and align management systems with ISO 45001 health and safety management to demonstrate systematic control of workplace risk.

Consider engaging with health and safety risk assessments when the update changes expectations on hazard identification or risk control.

Where relevant, plan for ongoing supplier management and worker consultation to embed the changes in governance, competent oversight and monitoring.

Timely adoption of NI’s EU Biocides Regulation and CLP implementation supports safer operations, clearer governance and ongoing regulatory compliance. Organisations should plan now to align risk assessment, control measures and monitoring with the NI requirements, supported by competent advice and appropriate management system enhancements.
