Communication in the supply chain
Directly after a substance is included in the Candidate List, suppliers of articles which contain such a substance in a concentration above 0.1% (weight by weight) have to provide enough information to allow the safe use of the article to the recipients of the article. In this case, recipients are industrial or professional users and distributors, but not consumers. As a minimum the name of the substance in question has to be communicated.
Consumers can request similar information. The supplier of the article has to provide this information within 45 days, free of charge.
