The end of the transition period for poison centre notifications is approaching. This means that all notifications for hazardous mixtures placed on the EU market must be in the harmonised format according to Annex VIII of the Classification, Labelling and Packaging (CLP) Regulation from 1 January 2025.

The transition period has allowed companies to continue placing their hazardous mixtures on the market according to non-harmonised national requirements. From 1 January 2025, these submissions will no longer comply with the CLP Regulation.

If companies intend to keep placing these mixtures on the market after this date, they will have to submit a new notification as required by Annex VIII and include the unique formula identifier (UFI) on the label. ECHA recommends notifiers to use the ECHA Submission portal to prepare and submit their information in the harmonised format.
