Poison Centres Notifications Update

Introduction: According to Annex VIII to the Classification, Labelling and Packaging (CLP) Regulation (EC) No 1272/2008, companies placing hazardous mixtures on the market have to notify Member State appointed Poison Centres with specific information. This information can then be used by the Poison Centres to give medical advice in the case of an emergency.

Who? Importers, downstream users, formulators or any company responsible for placing mixtures classified under CLP for human health or physical hazards on the market, must make the notifications to Poison Centres. This includes mixtures for consumer, professional and industrial use.

What? Such companies must use the harmonised Poison Centres Notification Format (PCN) format which is XML-based and compatible with IUCLID 6. Version 1.1 of the PCN format was published on 9th April 2019 and will be used for the submission of notifications via the PCN portal provided by ECHA and due to go live on 24th April 2019.

The same set of information will be required by all Member States where the mixture is placed on the market, which includes:

  • Contact details

  • Trade name of the mixture

  • Packaging type and size

  • Product category under the European Product Categorisation System (EuPCS)

  • The Unique formula identifier (UFI), the code generated by means of the UFI Generator

  • Information on the physical hazard or human health CLP classification of the mixture along with the label elements

  • Toxicological information for example to cover the ways in which a person might be exposed to the mixture and long- and short-term effects and symptoms from exposure

  • Information on physico-chemical properties for example the physical state and pH value of the mixture

  • Full composition of the  mixture

When?  The date from which this applies is dictated by the end use of the mixture, and if more than one option applies, you must chose the earliest date:

  • Mixtures for consumer use: 1 January 2020

  • Mixtures for professional use: 1 January 2021

  • Mixtures for industrial use: 1 January 2024

It is important to note that mixtures already notified under national legislation remain valid until 1 January 2025 but companies must make a notification based on the new information requirements according to Annex VIII if there is a change to the mixture before this date.
