How can I keep track of changes in harmonization?

New substances are regularly added to the list of substances with harmonized classifications, and existing classifications may be revised in light of new data.

To stay informed and anticipate any potential changes, you can visit the ECHA-CHEM website and go to the "CLH process" section under "Regulatory activities" on the ECHA-CHEM homepage #www.chem.echa.europa.eu#.
