All hazardous substances and mixtures placed on the GB market must be classified, labelled, and packaged in accordance with GB CLP regulations. The system uses the Globally Harmonised System (GHS) for consistent hazard communication.

Classification process

  • Gather data on substance properties (toxicity, flammability, environmental hazards)
  • Apply CLP classification criteria to determine hazard classes
  • Select appropriate GHS pictograms and hazard statements
  • Create compliant labels with all required elements

Safety Data Sheets

For substances and mixtures supplied for professional or industrial use, you must provide a 16-section Safety Data Sheet. The SDS must be updated when new hazard information becomes available or classification changes.
