EU: REACH – ECHA adds 3 substances to SVHC Candidate List

June 2025 - Electrical and electronics, hardlines, softlines, toys and children's products

On 25 June 2025, the European Chemicals Agency (ECHA) published the 33rd update of the REACH Candidate List¹. Three (3) new Substances of Very High Concern (SVHCs) were added. Now, the Candidate List includes 250 SVHCs².

During March and April 2025, the ECHA launched a public consultation, and proposed three new substances to be identified as SVHC. Now all the proposed substances are identified as SVHCs and included in the REACH Candidate List.

According to a recent ECHA’s news³, they will organise an ad hoc SVHC consultation for 1,1'-(ethane-1,2-diyl)bis[pentabromobenzene] (DBDPE) (EC 284-366-9, CAS 84852-53-9). The consultation is expected to launch on 27 June 2025, with a deadline of 11 August 2025. As a result, in addition to the two regular updates of the SVHC Candidate List, an extra ad hoc update will take place in 2025.

Table A gives the substance names, identification numbers (CAS and EC), the reason(s) for inclusion and their potential application(s).
