The Nordic Classification Group under the auspices of the Nordic Chemical Group/Nordic Council of Ministers has carried out a web-based survey to gain information on the view and practical experience of Nordic stakeholders on the applicability of UN GHS and the EU CLP regulation on the classification, labelling and packaging of substances and mixtures in relation to nanomaterials. The aim of the project was to identify potential challenges concerning classification and labeling due to the unique and complex characteristics of nanomaterials, and to provide input to the ongoing work in the UN Sub-Committee of Experts on GHS. The main outcomes of the survey are presented in the current report.
