CIRS Insights

Once a substance is included in the Candidate List, suppliers must fulfill the following statutory obligations:

1. Information Obligation for Substances in Articles

If an article (as defined) contains a substance on the candidate list at a concentration exceeding 0.1% weight by weight (w/w), sufficient information must be provided to the recipient of the article to ensure its safe use. The information shall as a minimum include the name of the substance. This obligation applies to the supply of articles to recipients who use or handle the articles in the course of their work. If a consumer (general public) makes a request, equivalent information must also be provided. The information must be provided within 45 days of receiving the request.

2. Notification of Substances in Articles

If articles containing a substance on the candidate list are manufactured, imported, or supplied, a notification may need to be submitted to HSE.

3. Information Obligation for Substances in Mixtures

If a supplied mixture is not classified as hazardous under GB CLP regulations but contains a substance on the candidate list at a concentration of 0.1% (w/w) or higher in a non-gaseous mixture, a safety data sheet must be provided upon request.

4. Information Obligation for Substances

If a supplied substance is included in the UK REACH candidate list, a safety data sheet (SDS) must be provided to the customer.
