A new regulation concerning the Registration, Evaluation, and Authorisation of Chemicals (⁠REACH⁠) was proposed by the European Commission on October 29, 2003 (EC, 2003a). The regulation puts major responsibility on industry for ensuring the safe manufacture, import, and use of chemicals throughout the chemical supply chain and for documenting this in their registration dossiers. Manufacturers and importers are required to conduct a chemical safety assessment (CSA) for substances manufactured or imported in a quantity above 10 tonnes per year.
