Here are five compelling reasons why PCN notification can become your "compliance accelerator."

In February 2026, the European Chemicals Agency (ECHA) published the Pilot Project Report on Poison Centre Notification (PCN) Enforcement.

As part of the ongoing effort to enhance safety and provide key information in the event of a chemical emergency, the European Union has introduced new requirements for the Poison Centre notification (PCN) under the Classification, Labelling and Packaging (CLP) Regulation and the Globally Harmonized System (GHS) framework. These changes are essential to ensure that relevant authorities can quickly access vital information in case of poisoning or hazardous exposure.

Since January 1, 2025, the grace period related to the Poison Center Notifications (PCN) to the European Union (EU) Poison Centers has come to an end. This means that companies must submit and successfully notify the unified format of notification dossiers before they can place their products on the EU market. After the deadline for industrial mixtures passed on January 1, 2024, the Hungarian appointed body has been conducting reviews of the submitted PCN dossiers. The main focus of the review is to check whether the information in the dossiers complies with the requirements of the CLP Regulation. The content of the PCN notification is mostly derived from the Safety Data Sheet (SDS) of the product, especially the toxicological information, which is the entire content of Section 11 of the SDS. Therefore, to pass the review by the Hungarian appointed body, companies must prepare an SDS that is fully based on the CLP standard when submitting the PCN notification.
