PRIO has been updated with new substances with EU-harmonised classification - ATP23

The twenty-third technical adaptation of the CLP Regulation, ATP 23, has been adopted by the European Commission. With ATP 23, more than 30 substances or groups of substances are added to Annex VI of the CLP Regulation with new or amended EU-harmonised classification and labelling. Based on ATP 23, the PRIO database has been expanded with substances that meet PRIO's criteria for phase-out substances or priority risk reduction substances.
