IMOクラス
The Carriage of dangerous goods and marine pollutants in sea-going ships is respectively regulated in the International Convention for the Safety of the Life at Sea (SOLAS) and the International Convention for the Prevention of pollution from Ships (MARPOL).
SOLASとMARPOLの関連部分は非常に詳細に検討されており、国際海上危険物（IMDG）コードに含まれているため、このコードは危険物と海洋汚染物質の海上輸送の法的手段になります。 2004年1月1日以降、IMDGコードは必須要件になります。
Classification of dangerous goods
すべての輸送モード（海上、空路、鉄道、道路および内陸水路）について、危険物の分類（グループ分け）は、関連するリスクの種類によって、国連危険物輸送専門家委員会によって作成された国連）。
Class 1: Explosives.
Subclass 1.1: Explosives
Consists of explosives that have a mass explosion hazard. A mass explosion is one which affects almost the entire load instantaneously.
Subclass 1.2: Explosives
Consists of explosives that have a projection hazard but not a mass explosion hazard.
Subclass 1.3: Explosives
Consists of explosives that have a projection hazard but not a mass explosion hazard.
Subclass 1.4: Explosives
Consists of explosives that present a minor explosion hazard. The explosive effects are largely confined to the package and no projection of fragments of appreciable size or range is to be expected. An external fire must not cause virtually instantaneous explosion of almost the entire contents of the package.
Subclass 1.5: Explosives
Consists of very insensitive explosives. This division is comprised of substances which have a mass explosion hazard but are so insensitive that there is very little probability of initiation or of transition from burning to detonation under normal conditions of transport
Subclass 1.6: Explosives
Consists of extremely insensitive articles which do not have a mass explosive hazard. This division is comprised of articles which contain only extremely insensitive detonating substances and which demonstrate a negligible probability of accidental initiation or propagation
