COP-6 Annex A amendments: UN Depositary notification triggers non-acceptance window; default entry into force 23 March 2027

The UN Depositary issued the formal notification of amendments to Annex A adopted at the sixth meeting of the Conference of the Parties (COP-6). This starts the one-year period during which Parties may notify non-acceptance. For Parties that do not opt out, the amendments will enter into force on 23 March 2027 (per the notification). Compliance teams supporting Minamata obligations should track whether jurisdictions of interest lodge non-acceptance or require an additional instrument (for Parties with relevant declarations), and prepare for downstream national implementing measures reflecting the Annex A changes (e.g., mercury-added product controls such as dental amalgam and lamp-related provisions as referenced in COP-6 materials).
