ECHA has updated the list of substances that might be chosen for compliance checks. The list includes 29 new substances. Registrants are advised to check this list and if needed, update their related registration dossiers and tonnage bands by 31 October 2017. The list gives registrants the possibility for early dossier updates before the compliance check starts. However, the list is indicative and non-exhaustive: ECHA reserves the right to open further compliance checks on any dossier at any time and without prior notice to the registrants.
