The IMDG Code has undergone many changes over the years, in both format and content, in order to keep up with the rapid expansion of the shipping industry. Amendment 37-14 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-third session in May 2014. The Code, as amended by Amendment 37-14, is mandatory as from 1 January 2016 but may be applied by Administrations in whole or in part on a voluntary basis from 1 January 2015. The two-volume Code is divided into seven parts: Volume 1 (parts 1, 2, 4, 5, 6 and 7of the Code) contains sections on: - general provisions, definitions and training - classification - packing and tank provisions - consignment procedures - construction and testing of packagings, IBCs, large packagings, portable tanks, MEGCs and road tank vehicles - transport operations. Volume 2 contains part 3 (Dangerous Goods List, special provisions and exceptions), appendices A and B (generic and N.O.S. Proper Shipping Names, and glossary of terms) and an index.
