Companies placing hazardous mixtures on the EU market need to be aware of their obligations under Annex VIII of the CLP (Classification, Labelling and Packaging) Regulation. Many EU Member States require that companies must notify a national poison centre, providing information that would be made available to medical personnel and the public in the event of a poisoning or accidental exposure.

When the CLP Regulation came into force in 2009, it included a requirement that the Member States create a body for receiving this information. A review was carried out to assess the possibility of harmonising the information required by poison centres, and this led to Annex VIII of the CLP Regulation, which entered into force in 2017. The provisions of the Annex will apply to products intended for consumer use from 1 January 2020, with products for professional use following on 1 January 2021 and products for industrial use from 1 January 2024.

The existing national requirements are being replaced by a single set of requirements and a single format of data submission, the PCN (Poison Centres Notification) format. The information is submitted via the ECHA Submission portal and made available to the relevant Member States’ appointed bodies. All submissions must include toxicological information as well as the full chemical composition. There is also a new label element called the Unique Formula Identifier (UFI), a code that links the information provided in the notification with the corresponding product placed on the market. This will help ensure that the poison centre can quickly identify the appropriate emergency health response.

For all products previously notified to national poison centres and already on the market, there will be a transitional period: these notifications will remain valid until 1 January 2025 or until changes are made to the product.
