Just a quick note: The ECHA CHEM platform (
https://chem.echa.europa.eu/) until recently contained the information on the EU-registration status of substances, only. Now, the content was siginificantly extended. On ECHA CHEM you will now find CLP-related information on the (registered) substances, like (harmonized) classifications, and relevant regulations, e.g. authorisations or restrictions. Makes the regulatory life somewhat easier, I think.....
