ADR 2027 (accepted) — no change for UN 3554
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.
This entry under ADR 2027 on the API: /api/adr?un=3554&edition=2027 (editions and as_of).
ADR 2025 is the edition that applies until ADR 2027 takes effect on 1 January 2027, and FreightUtils answers on it by default until then; the API answers on ADR 2027 now with edition=2027. After that date, ADR 2025 may still be applied until 30 June 2027 (1.6.1.1).
