Add an annotation to “List of the "ECHA Registered Substances" in machine-readable (ECHA)”

Annotations are so anyone, including you, can help the requester with their request. For example:

• Link to the information requested, if it is already available on the Internet.
• Suggest where else the requester might find the information.
• Offer better ways of wording the request to get the information.

Annotations will be posted publicly here, and are not sent to European Chemicals Agency.
