IMDG Code is intended to protect crew members and to prevent marine pollution in the safe transportation of hazardous materials by vessel.

Basis for national regulations[edit]

It is recommended to governments for adoption or for use as the basis for national regulations and is mandatory in conjunction with the obligations of the members of United Nations under the International Convention for the Safety of Life at Sea (SOLAS) and the International Convention for the Prevention of Pollution from Ships (MARPOL 73/78). It is intended for use not only by the mariner but also by all those involved in industries and services connected with shipping. Contains advice on terminology, packaging, labeling, placarding, markings, stowage, segregation, handling, and emergency response. The HNS Convention covers hazardous and noxious substances that are included in the IMDG code.


The code is updated and maintained by the CCC (formerly DSC) Sub-Committee of the International Maritime Organization every 2 years.
