ECHA has just published an information on the scope and timelines for certain hazardous substances that have already been identified under other laws to be added to Annex VI to CLP.

This information is related to the revised CLP Regulation which introduces a mechanism to integrate existing hazard identifications of substances to the list of harmonised classification and labelling entries, Annex VI to CLP. 

You can consult the timelines on ECHA’s website.
