Class 8 Corrosives: ADR 2027 Table A Changes

Class 8 is the most scattered of the sets. Ten changes reach five UN numbers and they spread across columns 18, 11 and 3b rather than concentrating in one. Four of the ten replace an existing value, so this is a class where the 2025 and 2027 entries are worth reading side by side rather than skimming for what is new.

What this page covers

This page carries only the Table A changes affecting corrosive substances such as acids and caustics. 10 individual changes across 5 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 3 of the 10 changes.
