Starting from January 1, 2024, the transition period established by the European Union for the PCN notification of mixtures for industrial use has also ended. All hazardous mixtures for professional, consumer, and industrial uses, such as those classified under GHS with specific physical or health hazards, are required to complete PCN notification before being placed on the EU market. This webinar aims to guide enterprises in determining whether PCN notification is necessary and in interpreting the UFI number.
