IMDG Code 2024: Amendment 42-24 and use in 2026

The 2024 edition of the IMDG Code incorporates Amendment 42-24. It is the mandatory edition for 2026; the edition year and its application date are different.

Which IMDG edition applies in 2026?

The IMO states that the 2024 edition, incorporating Amendment 42-24, became mandatory on 1 January 2026. Administrations could apply it voluntarily from 1 January 2025. A document labelled “2024” should therefore not be dismissed as out of date solely because a shipment takes place in 2026.

What does the Code cover?

The IMDG Code governs dangerous goods carried by sea in packaged form. Its framework covers classification, packaging, marking, labelling, documentation and operational matters such as stowage and segregation. IMO explains its relationship with SOLAS chapter VII and MARPOL Annex III on its IMDG scope page.

For a shipment involving a Spanish warehouse, road carrier and port, identify every transport stage before deciding which checks are needed. The sea-leg review should be coordinated with the requirements applicable to the other stages.

Official access and corrections

Use the IMO publication page to identify the edition and the official publication channels. This DGSA page is a reference guide and does not provide a free copy of the complete commercial Code.

For the English 2024 edition, consult the December 2025 errata and corrigenda (PDF). This is a correction document, not the full Code. When buying or using a copy, check its language, amendment number and applicable corrections together.

Preparing an enquiry about a shipment

For an efficient technical review, gather the product identity, available safety data sheet and transport classification, proposed packaging, quantities, route and sailing date. Explain who will pack the cargo unit and who will prepare the transport information.

These are starting points for a review, not a declaration that a shipment complies. Classification, packaging and acceptance decisions depend on the actual goods and operation. DGSA offers multimodal dangerous goods advice in English and Spanish for operations involving Spain.

For the packing of a container or other cargo transport unit, also see our CTU Code guide.
