You will need to comply with this code if you intend to be engaged in the international transport of dangerous goods by sea.
The International Maritime Dangerous Goods (IMDG) Code was developed as a uniform international code for the transport of dangerous goods by sea. It covers such matters as packing, container traffic and stowage, with particular reference to the segregation of incompatible substances.
The code outlines principles and recommendations for substances, materials and articles. The code also provides advice on terminology, packing, labelling, stowage, segregation and handling, and emergency response action.
