In accordance with Article 41 of the CLP Regulation it is the responsibility of the registrant(s) and notifier(s) of the same substance to make every effort to come to an agreed entry included in the Public C&L Inventory. However, ECHA has received millions of notifications for more than 100,000 substances for the C&L Inventory. Thus, the process of agreement for such a large number of notifiers and substances will be long and requires the active involvement of all parties concerned.
