Poison Centres Notification format
The Poison Centre Notification (PCN) format structures information on mixtures classified for health or physical hazards in accordance with Article 45 and Annex VIII to the CLP Regulation.
The format is XML-based, compatible with IUCLID, and available in the PCN dossier preparation tools offered by ECHA. It is also available for companies to prepare their own tools for dossier preparation, for example when using the system-to-system service.
The PCN format is updated annually in line with the IUCLID release schedule. The format is made available as a set of XML schema definition files (XSDs). The PCN data model shows all relevant fields and their interconnections.

PCN Key support
Key support for IT implementation
The Guide to the PCN Format and the Developers' Guide to the IUCLID Format are available to assist companies to build mechanisms other than IUCLID to generate the PCN format into their own IT systems.
Please refer to the list of PCN validation rules relevant for poison centres notifications which are incorporated into IUCLID and the ECHA Submission portal for running a series of automated checks.
In IUCLID, the exchange of chemical information is facilitated via a zip/archive file with the extension .i6z (IUCLID 6 zip). The information can be exported from one IUCLID 6 installation and imported into another. This file contains information concerning all (inter)related IUCLID 6 entities (documents and attachments), in a well-defined and structured format.
