Dangerous Goods ​ ​ Form

Form to be completed for the declaration of dangerous goods. The file is in Microsoft Excel format.


Packaging Group​

With the Packing groups the degree of danger of the transported substance is identified.​

Packing Groups are used for dangerous goods belonging to classes 3, 4, division 5.1, 6.1 and classes 8 and 9.

Identification of dangerous goods

Dangerous goods are assigned a UN (United Nations) number and Proper Shipping Names according to their hazard classification and composition.

Commonly transported dangerous goods are listed in the List of Dangerous Goods in paragraph 3.2 of the IMDG CODE (publication by the IMO). When a dangerous good is specifically listed by name, it must be identified during the transport phase from the Proper Shipping Name found in column (2) of list 3.2. In the case of dangerous goods not specifically listed by name, “generic ” or “not otherwise specified ” names must be used, these names are found in both paragraph 3.2 together with all generic names or in Appendix A where they are divided by class and therefore by type.

In list 3.2 we can recognize four different types of names:

  • single entries, when the good name identifies the substance or article as: UN 1090 Acetonegeneric entries,
  • when the good name identifies a group as: UN 1133 Adhesivesspecific nos entries, when
  • the name identifies a group of substances of a particular nature chemical or technical such as: UN 1987 Alcohols, nosgeneral entries, when the name
  • identifies the type of hazard as: UN 1993 Flammable liquid, nos

Shipping procedures / labeling


Each package containing dangerous goods must be marked with the UN number and the Proper Shipping Name of all dangerous goods contained therein.


The marking must be affixed to two opposite sides.


For special markings for radioactive materials, reference must instead be made to a different supplementary legislation.

Furthermore, in the case of packages containing goods considered to be maritime pollutants (MARINE

POLLUTANT), the appropriate mark shown in the IMO manual at point must also appear.


On each package containing dangerous goods, at least one danger label must appear indicating the main danger, any subsidiary risks listed in column 4 of the Dangerous Goods List (Chapter 3.2 of the IMO manual), and in some cases any risks subsidiaries indicated in column 6 of the DGL relating to Special Provisions.


Attention: in some cases the package containing dangerous goods is exempt from labeling but only requires a marking indicating the class. In this case, the special provision helps. Eg UN 1374 and Special provision 29.

If packages contain radioactive materials, they must have two danger labels on opposite sides.

Danger labels must be at least 10 x10 cm square in size at a 45 ° angle.

It is allowed to use smaller labels only to label cylinders containing class 2 gas. In this case the labels must be placed on the non-cylindrical part of the cylinders (shoulder).

The labels must be of such quality that they can withstand immersion in water for at least three months.


A transport unit containing dangerous goods or residues of it must report:

  • a danger label on each side and one at each end of the CTU, semi-trailer or mobile tank;
  • at least one on each side for a railway
  • wagon; on each side in correspondence with the relative compartments in the case of a multi-compartment tank containing plus a dangerous substance or their
  • residues; on both sides and on the back of the unit in the case of any other
  • transport unit. in paragraph special conditions for the labeling of transport unit with class 7, labels for transport
  • units must have a minimum size of 250x250mm.

  • The UN number must appear in black numbers


least 65 mm high: on a white background in the lower half of the label, or on a orange rectangular panel at

Paragraph shows examples of how to report UN numbers.

Particular indications they are needed in the case of transport of liquid

or solid materials at high temperatures ( or in the case of substances considered 'marine pollutant ' (


Transport units containing dangerous goods in limited quantities do not need to carry the danger labels. In any case, they must carry the writing on the outside: “LIMITED QUANTITIES ” or “LTD QTY ” not less than 65mm high.
