Are these changes already law?

No. They were adopted by WP.15 and notified on 1 July 2026 in depositary notification C.N.252.2026.TREATIES-XI.B.14. The objection window closes on 1 October 2026 and entry into force is set for 1 January 2027. ADR 2025 remains usable until 30 June 2027.

How many UN numbers are affected?

188 UN numbers. Four are entirely new (UN 3561, 3562, 3563, 3564), two existing UN numbers gain an additional entry (UN 2348 and UN 2862) and one entry is deleted (UN 2941). That is 231 individual column changes in total.

Which column changes most?

Column 13, special provisions for ADR tanks. A single instruction inserts special provision TM6 against 141 UN numbers, which makes it by far the largest single change in this cycle.

Where does the data come from?

The amendments are transcribed verbatim from ECE/TRANS/WP.15/274 plus Corr.1 and Add.1. The ADR 2025 baseline comes from the BAM Datenbank GEFAHRGUT under Datenlizenz Deutschland Namensnennung 2.0. Every row names its source document.

ADR 2027: Table A Synopsis

ADR 2027 Table A changes at a glance

231 individual column changes affect 188 UN numbers. Four UN numbers are entirely new (UN 3561, UN 3562, UN 3563 and UN 3564). Two existing entries gain an additional line (UN 2348 and UN 2862). One entry is deleted (UN 2941). The largest single amendment inserts special provision TM6 into column 13 against 141 UN numbers, which makes column 13 the most changed column of the cycle, with 144 of the 231 changes.

Baseline is the BAM Datenbank GEFAHRGUT ADR 2025 dataset. Amendments are transcribed verbatim from ECE/TRANS/WP.15/274 with Corr.1 and Add.1, notified in UN depositary notification C.N.252.2026.TREATIES-XI.B.14 of 1 July 2026. The amendments are adopted but not yet in force: they apply from 1 January 2027, and ADR 2025 remains usable until 30 June 2027.

Changes by ADR class

If you only need one class, these are the subsets. Each page is separately citable and carries its own source reference.

Class 1, explosives 5 changes across 2 UN numbers
Class 2, gases 158 changes across 146 UN numbers
Class 3, flammable liquids 18 changes across 4 UN numbers
Class 5.2, organic peroxides 10 changes across 10 UN numbers
Class 6.1, toxic substances 6 changes across 5 UN numbers
Class 8, corrosives 10 changes across 7 UN numbers
Class 9, miscellaneous 19 changes across 10 UN numbers

Vektor Group has compiled every change to Table A between ADR 2025 and ADR 2027 into a single register searchable by UN number: 231 individual column changes across 182 UN numbers, plus six whole-entry changes, 188 UN numbers affected in total, transcribed verbatim from ECE/TRANS/WP.15/274 with Corr.1 and Add.1, each row carrying its source reference. The amendments are adopted but do not enter into force until 1 January 2027, and ADR 2025 remains usable until 30 June 2027. The register is free and available under CC BY 4.0: https://vektorgroup.eu/adr-2027-changes

Whole entry changes in the proposed ADR 2027 amendments

A whole entry change adds, deletes or replaces an entire row of Table A, so there is no column level before and after value to compare. These seven records are therefore presented separately from the 231 column changes.

Proposed ADR 2027 whole entry changes, sourced to ECE/TRANS/WP.15/274 and its Corrigendum 1.
