ADR 2027 was accepted: depositary notification C.N.395.2026 (9 October 2026) records no objection to the amendments proposed by C.N.252.2026. It applies from 1 January 2027, and ADR 2025 may still be applied until 30 June 2027 (1.6.1.1). (C.N.395.2026)
ADR 2027: no Table A change for this entry (checked against ECE/TRANS/WP.15/274, Add.1 and Corr.1). Other parts of ADR 2027 may still affect its carriage.
ADR 2025 remains the edition FreightUtils serves and the one that applies until ADR 2027 takes effect on 1 January 2027; after that, ADR 2025 may still be applied until 30 June 2027 (1.6.1.1).
ADR 2025 Table A lists UN 2455 (METHYL NITRITE) as “CARRIAGE PROHIBITED” — it may not be carried by road under ADR. No packing group, transport category, or 1.1.3.6 small-load exemption applies: the entry is banned from carriage, not exempt from it.
