On June 15, 2026, the UK Health and Safety Executive (HSE) officially announced the addition of 15 substances/substance groups to the UK REACH Candidate List of Substances of Very High Concern (SVHC). This represents the first substantive update to the Candidate List since the end of the UK's Brexit transition period in 2021. CIRS Group provides the following interpretation of this update.
Background
The HSE launched a six-week public consultation on March 9, 2026, to solicit stakeholder input on the properties and hazard characteristics of the 15 substances/substance groups. The consultation closed on April 20. All 15 substances/substance groups had been identified as SVHCs and listed in the EU Candidate List by the European Chemicals Agency (ECHA) between 2021 and 2025, and all hold mandatory harmonized classifications under the UK GB CLP Regulation, primarily involving Carcinogenicity, Mutagenicity, or Reproductive Toxicity (CMR) categories.

Compliance Obligations for Enterprises
Once substances are added to the Candidate List, suppliers must immediately fulfill the following statutory obligations:
1. Information Communication Obligation for Substances in Articles
If an article (as defined) supplied 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 safe use. The information shall include at a minimum the name of the substance. This obligation applies when supplying to recipients who use or handle the article in the course of their work.
If a consumer (member of the general public) makes a request, equivalent information must also be provided.
This information must be provided within 45 days of receipt of the request.
2. Notification of Substances in Articles
If producing, importing, or supplying articles containing substances on the Candidate List, notification to the HSE may be required.
3. Information Communication Obligation for Substances in Mixtures
If a mixture supplied is not classified as hazardous under the GB CLP Regulation but contains a substance on the Candidate List at a concentration of 0.1% (w/w) or higher in non-gaseous mixtures, a safety data sheet must be provided upon request.
4. Information Communication Obligation for Substances
If a substance supplied is listed on the UK REACH Candidate List, a safety data sheet (SDS) for that substance must be provided to the customer.
