2027 transport regulation cycle: consolidated amendments published
The 2027 dangerous-goods transport cycle is moving from technical drafting into implementation planning. UNECE notified ADR/ADN 2027 amendments to Contracting Parties on 1 July 2026, with entry into force expected 1 January 2027 absent objections by 1 October 2026 — including new provisions for lithium-ion, sodium-ion and hybrid batteries and emerging hydrogen transport. Air (ICAO TI / IATA DGR) and sea (IMDG Amendment 43-26) modes are on their own, related cycles. Companies should treat SDS Section 14, transport master data and logistics rule sets as three places that can drift out of sync if not updated together.
