UK REACH adds 15 new substances to the SVHC Candidate List
On June 15, 2026, the Health and Safety Executive (HSE) added 15 new substances and substance groups to the UK REACH Candidate List of Substances of Very High Concern (SVHC). This update represents a significant expansion of the list and may affect manufacturers, importers, and distributors who market substances and mixtures in the UK market.
The inclusion of new substances in the Candidate List means that companies must check whether any of their products contain these substances and assess the impact on their regulatory obligations, including Safety Data Sheets (SDS), classification, labelling and other technical documentation.
What is the UK REACH Candidate List?
The Candidate List brings together substances identified as Substances of Very High Concern (SVHC) due to their hazardous properties for human health or the environment.
These substances may be candidates for later inclusion in the Authorisation List, which would involve additional restrictions on their use or marketing.
The list is managed by the Health and Safety Executive (HSE) within the UK REACH regulatory framework.
The 15 new substances added
The added substances and substance groups are:
- Barium diboron tetraoxide
- Bis (α,α-dimethylbenzyl) peroxide
- BMP/TBNPA/2,3-DBPA
- DBMC
- Diphenyl (2,4,6-trimethylbenzoyl) phosphine oxide
- DOTL (and related dioctyltin derivatives)
- Lysmeral
- N-(hydroxymethyl) acrylamide
- Omnirad
- Orthoboric acid, sodium salt
- Reactive Brown 51
- TBBPA
- Tetra-PSCA
- Tetraglyme
- Tris (2-methoxyethoxy) vinylsilane
Who is affected by this update?
The update may particularly affect companies that:
- manufacture chemical substances;
- formulate mixtures;
- import chemicals into the United Kingdom;
- distribute substances or mixtures subject to UK REACH;
- market products containing any of these substances.
Organizations should verify if any of the new SVHCs are present in their raw materials or products and check if regulatory documentation needs to be updated.
What actions should companies take?
Following the update of the Candidate List, it is recommended to:
- review the inventory of substances and mixtures;
- check if any of the new SVHCs are part of the product composition;
- assess the impact on classification and labeling;
- update Safety Data Sheets where necessary;
- verify the applicable communication obligations under UK REACH.
An early review helps keep documentation aligned with regulatory requirements and reduces the risk of non-compliance.
