Key Regulatory data, the new Classification & Labelling (C&L) Inventory, and REACH Registration data can now be found in ECHA CHEM. For the time being regulatory data here are still updated daily. The old C&L Inventory was last updated on 30 September 2025. REACH Registration and C&L Inventory data will be removed from here by 18 December 2025. Due to a technical upgrade and the coming holidays, data on ECHA CHEM will remain frozen between 5 December 2025 and 10 January 2026.
