The International Maritime Dangerous Goods Code (IMDG Code) includes revisions to various
sections of the Code and to transport requirements for specific substances. It was adopted by IMO’s
Maritime Safety Committee (MSC) at its ninety-ninth session in May 2018.
Amendment 39-18 of the Code is mandatory from 1 January 2020 but may be applied by
Administrations on a voluntary basis from 1 January 2019.
The two-volume Code is divided into seven parts:
Volume 1 comprises parts 1, 2, 4, 5, 6 and 7 of the Code
Volume 2 contains part 3 (Dangerous Goods list, special provisions and exceptions), appendices A
and B and an index.
