What this page covers

This page carries only the Table A changes affecting organic peroxides, which are thermally unstable and often temperature controlled. 10 individual changes across 10 UN numbers.

The amendments are proposed and not yet in force: under UN depositary notification C.N.252.2026 they are deemed accepted unless at least one third of the ADR Contracting Parties, or five of them, object by 1 October 2026, and then enter into force on 1 January 2027. Under 1.6.1.1 as amended, ADR 2025 may then still be used until 30 June 2027 unless otherwise specified.

The most changed column in this class is column 18, with 10 of the 10 changes.

Sources: ECE/TRANS/WP.15/274 with Corr.1 and Add.1. Baseline ADR 2025, BAM Datenbank GEFAHRGUT.
