Substance evaluation

Under Substance Evaluation, Member States assess certain substances to clarify whether their use poses a risk to human health or the environment. The objective is to request further information if necessary from the registrants of the substance, in order to verify the alleged concern. The substances prioritised for such evaluation are listed in the Community Rolling Action Plan (CoRAP). Only registered substances can be subject to substance evaluation. After evaluating, Member States may propose to request further information from registrants if the available information does not fully address the potential risks. This request may include a test or data beyond the standard REACH information requirements. ECHA coordinates and supports the work of Member States. ECHA is also in the position to propose amendments on the draft decisions made by the Member States. The evaluation may in the end conclude that the risks are sufficiently under control with the measures already in place. Otherwise, it may lead to the proposal of EU-wide risk management measures such as restrictions, identification of substances of very high concern, harmonised classification or other actions outside the scope of REACH.
