Seveso III Data
Disclaimer: Please note that some of the substances covered by the Seveso Directive can belong to more than one Seveso categories. It will be up to the users to decide whether their substance or mixture fall in one or in more of these classification categories depending on the tonnage bands and the concentrations.
Please also note that ECHA is not an authority for the Seveso Directive and that the Seveso categorisation below is provided for information only. The Seveso III Directive (Directive 2012/18/EU repealing Directive 96/82/EC (Seveso II) from 1 June 2015) is the only authentic legal reference and that the information in this inventory does not constitute legal advice. For further information on Seveso, please ask your national authority.
