In 2016, the European Chemicals Agency (ECHA) focused its dossier evaluation activities on substances with the greatest potential to negatively affect people and the environment: substances produced in high volumes – over 100 tonnes per year – and with a potential concern. To encourage registrants to update their dossiers already before compliance checks or risk management actions take place, ECHA sent letters to the registrants of 270 substances of potential concern, highlighting the deficiencies in their dossiers. The Agency also regularly published a list of substances that may be chosen for compliance checks. If the companies do not react by the deadline stipulated by ECHA, their registration will be revoked.
