General definition

Materials and things are defined as hazardous cargo which, due to their nature, characteristics, or their state, could endanger the public safety and order, in particular the public at large, important common property, life and health of human beings as well as animals and the environment and other things.

Relevant regulations for sea transportation
  • IMDG Code (International Maritime Dangerous Goods Code)
  • IMSBC Code (International Maritime Solid Bulk Cargoes Code)
  • IBC Code (International Code for the Construction and Equipment of Ships Carrying Dangerous Chemicals in Bulk)
  • IGC Code (International Code for the Construction and Equipment of Ships Carrying Liquefied Gases in Bulk)
  • INF Code (International Code for the Safe Carriage of Packaged Irradiated Nuclear Fuel, Plutonium and High-level Radioactive Wastes on Board Ships)
There might be some dangerous goods which could be restricted or prohibited by carrier’s in-house policy or local regulation independent of IMDG code.

DG cargo Application

Shipper should submit the application to sales office at least four (4) working days in advance prior to vessel's arrival at the loading port. Application for high risk special dangerous cargoes such as explosives, self-reactive substances, organic peroxides will be made at least seven (7) working days in advance prior to vessel's arrival at the loading port.

Acceptance or Rejection for shipment

SM LINE confirms acceptance or rejection within one (1) working day.


Whenever the DG cargo is loaded on board vessel, the Shipper shall prepare necessary documentation required by IMDG code, 49CFR or other local regulation of calling and transit ports such as Declaration of Dangerous Goods, Declaration of Dangerous Goods in Container and Container Packing Certificate etc

DG Classification

Substances (including mixtures and solutions) and articles subject to the provisions of IMDG Code are assigned to one of the classes 1-9 according to the hazard or the most predominant of the hazards they present. Some of these classes are subdivided into divisions.

Class 1 : Explosives

  • substances and articles which have a mass explosion hazard
  • substances and articles which have a projection hazard but not a mass explosion hazard
  • substances and articles which have a fire hazard and either a minor blast hazard or a minor projection hazard or both, but not a mass explosion hazard
  • substances and articles which present no significant hazard
  • very insensitive substances which have a mass explosion hazard
  • extremely insensitive articles which do not have a mass explosion hazard

Class 2 : Gases
  • - A Gas is a substance which;
  • 1. at 50°C has a vapour pressure greater than 300kPa or
  • 2. is completely gaseous at 20°C at a standard pressure of 101.3 kPa

  • flammable gases
  • non-flammable, non-toxic gases
  • toxic gases

Class 3 Flammable liquids

Flammable liquids are liquids, or mixtures of liquids, or liquids containing solids in solution or suspension (such as paints, varnishes, lacquers, etc., but not including substances which, on account of their other dangerous characteristics, have been included in other classes) which give off a flammable vapour at or below 60°C closed-cup test (corresponding to 65.6°C open- cup test) If the flash point is under 60°C in case that IMO label is not class 3, then the Subsidiary risk label should be class 3.

Class 4 Flammable solids

  • flammable solids, self-reactive substances and solid desensitized explosives
  • substances liable to spontaneous combustion
  • substances which, in contact with water, emit flammable gases

Class 5 Oxidizing substances and organic peroxides

  • oxidizing substances
    - Substances which, while in themselves not necessarily combustible, may, generally by yielding oxygen, cause, or contribute to the combustion of other material.
  • organic peroxides
    - Organic peroxides are liable to exothermic decomposition at normal or elevated temperatures. The decomposition can be initiated by heat, contact with impurities (such as acids, heavy-metal compounds, amines), friction or impact. The rate of decomposition increases with temperature and varies with the organic peroxide formulation. Decomposition may result in the evolution of harmful, or flammable, gases or vapours.

Class 6 Toxic and infectious substances

  • toxic substances
    - These are Substances liable either to cause death or serious injury or to harm human health if swallowed or inhaled, or by skin contact
    - Nearly all toxic substances evolve toxic gases when involved in a fire or when heated to decomposition.
  • infectious substances
    - Substances known or reasonably expected to contain pathogens.

Class 7 Radioactive material

- Radioactive material means any material containing radionuclides where both the activity concentration and the total activity in the consignment exceed the values specified in IMDG code to

Class 8 : Corrosive substances

- substances which, by chemical action, will cause severe damage when in contact with living tissue or, in the case of leakage, will materially damage, or even destroy, other goods or the means of transport.

Class 9 : Miscellaneous dangerous substances and articles

- substances and articles which, during transport, present a danger not covered by other classes.
