Since the UK left the EU, chemical regulations have been evolving under the domestic GB CLP framework. The latest updates to the Classification, Labelling and Packaging (CLP) Regulation bring several changes that directly affect how businesses label chemical substances and mixtures. If you manufacture, import, distribute, or sell chemical products in Great Britain, here’s what you need to know.
Key Changes in the 2025 CLP Update
The most recent changes, expected to be fully enforced by late 2025, aim to bring GB CLP more in line with the latest Globally Harmonized System (GHS) revisions, while also reflecting UK-specific regulatory priorities.
Here are the main updates:
- New hazard classes: GB CLP will include several new hazard categories such as endocrine disruptors and persistent, bioaccumulative and toxic (PBT) substances. These are intended to help users better understand long-term health and environmental risks.
- Revised classification process: Companies must now consider updated technical guidance and scientific data when classifying chemicals. This includes a stronger emphasis on weight-of-evidence approaches.
- Dual-labelling guidance: Products sold in both the UK and EU may require dual CLP labels to meet compliance in both markets, especially where classifications differ.
- Digital labelling options: Although still under consultation, the UK is exploring the use of digital labels for certain types of supplemental information, such as QR codes linking to safety data sheets.
What Businesses Must Do
To stay compliant, chemical businesses operating in Great Britain should take the following steps:
- Review product classifications against the new hazard categories and update as needed.
- Check label elements such as signal words, hazard pictograms, and precautionary statements to reflect any reclassifications.
- Update safety data sheets (SDS) in accordance with the revised classification and labelling data.
- Train employees and distributors on the changes to avoid mislabeling or mishandling products.
- Prepare for enforcement: Non-compliance may lead to penalties or product recalls. Authorities such as the HSE (Health and Safety Executive) will begin inspections based on the new rules.
Timing and Transitional Periods
A transitional period will apply to allow businesses to adapt, but this window will close quickly. Products already on the market before the final enforcement date may be allowed to stay under old labels temporarily. However, newly manufactured or imported products will need to fully comply.
Final Thoughts
These new CLP guidelines are more than an administrative update. They reflect a growing emphasis on public health, environmental safety, and transparency. Chemical businesses should act early to review their compliance, update systems, and communicate changes clearly across their supply chain. Proactive steps now can help avoid disruption later.
