On 12 October 2018, the UK government published a technical notice on how a no-deal Brexit may impact on the regulation of the classification, labelling and packaging of chemicals (CLP).

This technical notice states that in a no-deal scenario, the UK CLP regime would generally be based on the existing EU CLP regime to provide continuity for businesses, but with amendments to allow functions presently carried out by the EU, including the European Chemicals Agency (ECHA), to be carried out in the UK by the Health and Safety Executive (HSE).
