REACH (Registration, Evaluation, Authorization and Restriction of Chemicals, EC 1907/2006) is the European Union’s chemical regulation that requires that chemical substances on their own, in preparations and all intentionally released substances from articles must be registered with the European Chemicals Agency (ECHA).

The regulation applies to substances manufactured in, or imported to the EU in annual quantities of 1 ton or more. According to the REACH requirements on Substances of Very High Concern (SVHC) a supplier of manufactured and imported articles shall provide customers with information on SVHC if they are present above a concentration limit of 0.1 % on an article level. SVHC will be defined through the list of candidate substances for authorization that is produced by the European Chemicals Agency.
