The harmonised notification to Poison Centres in the EU is the process through which manufacturers, importers, or downstream users report to the authorities the composition and hazards of hazardous chemical mixtures. Established under the CLP Regulation, this procedure standardises the format and content of the information across the European Union, enabling poison centres to provide fast and accurate medical advice in case of an emergency.

A significant portion of the data submitted in the notification —such as CLP classification, detailed composition, or first-aid measures— is taken from toxicological sheets or the Safety Data Sheet (SDS). This highlights the importance of keeping these documents complete and up to date. Meeting this requirement not only helps avoid penalties but also ensures that, in the event of an incident, healthcare professionals can respond quickly and effectively.

The PCN Format (Poison Centre Notification Format) is the digital standard defined by ECHA for carrying out the harmonised notification of hazardous mixtures. Through this format, companies transmit product information in a structured way, ensuring compatibility with the systems of all EU Member States.

The submission is carried out via the IUCLID platform or the ECHA portal, following specific technical requirements. It is also possible to optimise the process by using automation software, such as eQgest, which enables faster and safer preparation and submission of the notification, reducing errors and saving up to 85% of execution time.

Managing this procedure accurately ensures regulatory compliance, minimises operational risks, and safeguards the company’s reputation in the European market.
