ECHA would like to know about the challenges you face when preparing the CLH dossiers and how their guide “How to submit a CLH dossier” is helping you on this matter.

You can submit your feedback by filling in this survey by 15 September 2021. Your comments will help ECHA to prepare a second information session on this topic later in the autumn. If you miss the first session you can watch the recording and read a summary of the questions and answers on ECHA’s website.
