The European Chemicals Agency (ECHA) has released an updated version of its Classification and Labelling (C&L) Inventory, now accessible through the ECHA CHEM database. This revamped inventory offers enhanced features that improve the visualisation of information on both harmonised and self-classified substances. It encompasses data on over 4 400 EU-level harmonised classifications and approximately 7 million classifications notified under REACH. The redesign aims to facilitate access and improve understanding of chemical hazard information for stakeholders, including industry professionals and regulatory authorities.
