One of the key developments in this area is the enhanced Poison Centre Notification (PCN) process. As of 1 January 2025, all businesses that manufacture or import hazardous mixtures into the EU market will be legally required to submit a Poison Centre Notification. They must either submit their own notifications or ensure that the supplier includes their product data in the original Poison Centre Notification submission. – Any updates to the product formulation will require a new UFI and an updated Poison Centre Notification, and the product labelling must be revised accordingly. – By harmonising Poison Centre Notification requirements across Europe, the EU aims to improve response times and outcomes in chemical emergencies.
