Classification, Labelling and Packaging (CLP)

Our first involvement in the harmonised EU criteria for classification, labelling and packaging was at the advent of the Dangerous Preparations Directive (DPD, 1999/45/EC), where our scientists managed the reclassification of many corporate portfolios. The Classification, Packaging and Labelling (CLP) Regulation No. 1272/2008 which entered into force on 20th January 2009 has replaced the DPD and Dangerous Substances Directive (67/548/EEC) in the EU, and implements the United Nations’ Globally Harmonised System of Classification and Labelling of Chemicals (UN GHS). The CLP labelling provisions take on board the red-framed hazard pictograms, signal words, and hazard and precautionary statements provided for in the UN GHS.

Since the 1st June 2015 the CLP Regulation has applied to chemical mixtures (formerly products/preparations), with respect to classification, labelling and packaging requirements. As with the previous legislation, the CLP Regulation is intended to be primarily a self-classification system for companies, using test data available on the mixture, bridging principles or the conventional calculation method.

We are competent to assist you in meeting your CLP obligations to:

  • Gather and evaluate all relevant and reliable information on physical, health and environmental hazards
  • Identify the relevant information for all relevant hazard classes/categories
  • Evaluate against the CLP criteria to arrive at a suitable classification
  • Liaise with competent authorities for submission of revised classification
  • Prepare the revised product Safety Data Sheet (SDS)
  • Prepare the revised product CLP label

Safety Data Sheet Preparation

Safety data sheets (SDSs) provide useful information on substances and chemical mixtures, describing the hazards presented, and giving information on handling, storage and emergency measures in the case of an accident or emergency. An SDS must be supplied with hazardous substances, and with mixtures containing hazardous substances above thresholds of concern. EU SDSs must be prepared in accordance with the format prescribed in Annex II of the REACH Regulation (Regulation (EC) No 1907/2006), as updated by the Regulation (EU) No 453/2010. Over the coming years, there will be a gradual transition to the extended SDS (eSDS) which will include further information on safe handling, in the form of exposure scenarios. REACH requires users of hazardous chemicals to follow the advice on risk management measures given in the exposure scenario.

For the EU, it is a requirement that the person responsible for compiling an SDS is ‘competent’, that is, that they have the relevant experience, knowledge and training. Our competent experts provide EU SDS compilation and translation services for our clients.
