The restriction process is a central instrument of ⁠REACH⁠ to regulate risks of substances by means of a restriction or prohibition for certain concentration ranges and uses. This project analysed the current implementation of the process based on a literature review and case studies with a focus on the workload for authorities, the duration of the procedure and the role oft he committees. Overall, the restriction procedure is evaluated as working well - nevertheless, the authorities’ workload could be reduced and the procedure be accelerated. The report comes up with proposals to make the restriction procedure more simple, efficient and faster.
