IMDG Code Amendment 40-20 Books Volumes 1 and 2 and IMDG Code Supplement (2021 release)

The IMDG Code Amendment 40-20 can be used on a voluntary basis from 1 January 2021. It becomes mandatory as from 1 June 2022 and can be used until 31 December 2023.

What is in it: The IMDG Code lays down basic principles on the transport of dangerous goods by sea. It contains detailed recommendations for individual substances, materials and articles, and a number of recommendations for good operational practice, including advice on terminology, packing, labelling, stowage, segregation and handling, and emergency response action.

Who uses it: Although the information in the Code is directed primarily at the mariner, its provisions may affect a range of industries and services, such as manufacturers, packers, shippers and feeder services such as road and port authorities.

The two-volume IMDG Code is divided into seven parts:

Volume 1

  • general provisions, definitions, training
  • classification
  • packing and tank provisions

  • transport operations
Volume 2

Contains part 3 (Dangerous Goods List, special provisions and exceptions), appendix A (generic and N.O.S. Proper Shipping Names), appendix B (Glossary of terms) and an index.
