As with other substances on the Candidate List, these newly added substances are not eligible for the EU Ecolabel award under the EU Ecolabel Regulation. Besides, if they are later included in the Authorisation List, companies will not be allowed to use them unless they apply for authorisation and the European Commission grants permission for continued use.
What Does Inclusion in the Candidate List Mean?
According to the REACH Regulation, inclusion of a substance on the Candidate List—whether on its own, in mixtures, or in articles—triggers certain legal obligations for companies. For articles containing these substances at concentrations above 0.1%, suppliers must inform consumers about the safe use of their products.
ECHA has stated that importers and manufacturers must notify ECHA about any products containing these substances within six months from 25 June 2025. Safety data sheets (SDS) must also be updated accordingly.
