The Classification, Labelling and Packaging (CLP) Regulation is the cornerstone of chemicals hazard communication in the UK. Through the classification of substances and mixtures, and the communication of hazards via labels and safety data, the Regulation helps ensure the safe supply, use and transport of chemicals whilst supporting the protection of human health and the environment.

As governments review policy on chemicals and consider future regulatory developments, including the introduction of new hazard classes and greater alignment with international initiatives, it is important that CLP remains firmly grounded in sound science and international harmonisation. Divergence from globally agreed approaches can create unnecessary complexity, increase costs for businesses and supply chains, and make compliance more challenging, particularly for companies operating across multiple jurisdictions.

The United Nations Globally Harmonized System of Classification and Labelling of Chemicals (GHS) provides the internationally recognised framework for hazard communication under CLP. Continued alignment with GHS supports consistency, facilitates international trade, and ensures that regulatory requirements remain understandable and workable for manufacturers, importers, downstream users, and enforcement authorities.

Effective hazard communication is essential, but regulatory changes should be evidence-based, proportionate, and developed in close consultation with stakeholders to ensure that the benefits outweigh any unintended impacts on innovation, competitiveness and supply chain resilience.

ACTIONS:

  • Consider the cumulative impacts of classification and labelling changes on industry, innovation, product availability and supply chain resilience when developing future classification and labelling policy.
  • Ensure that any new hazard classes or classification criteria are supported by robust scientific evidence, internationally agreed methodologies and clear guidance for implementation.
  • Continue to promote the use of high-quality scientific data (including, where appropriate, data generated via New Approach Methodologies) in regulatory decision-making.
  • Maintain close alignment between GB CLP and the United Nations GHS to support international consistency, facilitate trade, minimise unnecessary regulatory burden, and preserve the UK’s place within (and contributing to) the global framework.
  • As far as is reasonably possible, avoid unnecessary divergence between GB and EU classification and labelling requirements where there is no demonstrable benefit to human health, environmental protection or market functioning, whilst recognising the necessity of divergence from EU classifications in cases of scientific disagreement and significant impacts on the UK market.
  • Ensure realistic transitional arrangements and timelines are provided for significant regulatory changes to provide industry, with sufficient time given to update classifications, labels, packaging, safety data sheets and supply chain communications.
  • Provide timely and practical guidance from regulators to ensure consistent interpretation and implementation of new classification requirements.
