ADR 2027 Table A changes, Class 2, gases

Class 2 carries the bulk of the amendments: 158 changes across 146 UN numbers, more than two thirds of every change in Table A. 142 of them fall in column 13, special provisions for ADR tanks, and 141 are insertions rather than replacements, so most gas entries gain a provision rather than having one rewritten.

This page carries only the Table A changes affecting compressed, liquefied and dissolved gases. 158 individual changes across 146 UN numbers. The amendments are adopted but do not enter into force until 1 January 2027, and ADR 2025 remains usable until 30 June 2027.

The most changed column in this class is column 13, with 142 of the 158 changes.
