SG 087/26
The United Kingdom (UK) adds 15 entries to the Candidate List of substances of very high concern (SVHCs) for authorization.
In March 2026, the UK’s Health and Safety Executive (HSE) consulted on its proposed addition of 15 SVHCs to the UK REACH Candidate List for authorization (SafeGuardS 40/26).
On June 15, 2026, the UK’s HSE added 15 SVHCs/groups of SVHCs to the UK REACH Candidate List. Further details on these groupings are also available in the Registry of SVHC intentions until outcome (RoI).
What are the newly added 15 SVHCs on the UK REACH Candidate List?
These 15 SVHCs and examples of their uses are detailed in Table 1.

What does this regulation require?
Once a substance is placed on the UK REACH Candidate List, suppliers of the substance have legal obligations when this substance is included either on its own, in mixtures or in articles.
Duty to communicate on substances in articles
Suppliers of an article containing a UK REACH Candidate List SVHC in a concentration of more than 0.1% are required to provide information to the recipient of the article to allow the safe use of the article. This equivalent information should be supplied to consumers (the general public) within 45 days when requested.
Duty to notify HSE under UK REACH
UK producers, importers and suppliers of an article are obliged to notify the HSE if their article contains a substance on the UK REACH Candidate List. This applies if the substance meets two conditions:
- The substance is present at more than 0.1% in those articles, and
- The substance is present in those articles in quantities totaling more than one tonne per producer or importer per year
The notification must be submitted within six months from the date the substance is included on the list.
Duty to communicate on information on substances
Suppliers of substances on the UK REACH Candidate List, either on their own or in mixtures, are obliged to provide their customers with an up-to-date safety data sheet (SDS).
Who is impacted?
Stakeholders across multiple industries and supply chains are affected. This includes manufacturers, importers and suppliers of SVHCs, whether these substances are present on their own, in mixtures or in articles, operating in the Great Britain (England, Scotland and Wales) market.
When does it apply?
The legal obligations mentioned above apply from June 15, 2026.
