The edition for operations in 2025 and 2026
ICAO identifies the 2025–2026 edition of Doc 9284 as applicable to operations from 1 January 2025 to 31 December 2026. The Technical Instructions develop the principles in Annex 18 to the Chicago Convention.
Record the edition and language used in a company procedure. A familiar UN number, an older training handout or a road transport classification cannot establish all the conditions for an air shipment. The reference needs to match the operation and its date.
The Spanish publication and its reference
The Resolution of 29 November 2024, published in the BOE on 13 December 2024, publishes the nineteenth biennial edition of the Technical Instructions for safe carriage of dangerous goods by air.
Use the BOE reference when identifying the Spanish publication. Keep it with the applicable corrections and subsequent changes. The initial publication date does not demonstrate that a retained copy includes updates issued during the two-year edition.
Check subsequent addenda and corrections
The ICAO Doc 9284 register, checked on 12 October 2026, lists Addendum No. 1 dated 27 March 2026 and Corrigendum No. 2 dated 7 May 2026. It also distinguishes language-specific corrections.
Select the documents for the language being used and check their application dates and affected provisions. Update the controlled reference when a correction affects a procedure. The existence of a later edition for sale does not by itself change the edition applicable to a current shipment.
Assess the actual air transport chain
ICAO’s Technical Instructions contain the detailed requirements. A short overview cannot determine acceptance of a particular consignment. Review the goods, aircraft operation, packaging, quantities, documents and the roles performed.
Check applicable State variations and the intended operator’s conditions before confirming the arrangement. Keep the air assessment separate from any connecting road journey. Our transport SDS guide explains why an SDS is one input to a transport review rather than a complete shipment decision.
Prepare documents for a focused review
A useful review file records the substance or article, current classification evidence, proposed transport modes, relevant dates, participants and the edition references used. Identify unresolved questions before the consignment is offered for carriage, and retain the applicable documents with the procedure.
DGSA advisory services can support the dangerous goods documentation interface. Contact DGSA with the operation and available evidence so the review reflects the actual transport chain.
