ECHA confirms Candidate List dataset remains the authentic reference during transition to ECHA CHEM; legacy Candidate List table maintained until July 2026

ECHA is transitioning REACH regulatory datasets (including the SVHC Candidate List and SVHC identification information) to its new public database, ECHA CHEM. ECHA states that the Candidate List published on its website is the only “authentic version” and that it will keep the legacy Candidate List dataset/page up to date until July 2026 to support the transition. Compliance teams should update monitoring and integrations (e.g., bookmarks, automated checks, supplier communication references) to include ECHA CHEM while continuing to rely on ECHA’s Candidate List as the authoritative legal reference during the transition period.
