Marking and labelling of packages including IBCs
- These provisions relate essentially to the marking and labelling of dangerous goods according to their properties. However, additional markings or symbols indicating precautions to be taken in handling or storing a package (such as a symbol representing an umbrella, indicating that a package shall be kept dry) may be displayed on a package if appropriate.
- Marking of packages including IBCs
Unless provided otherwise in this Code, the proper shipping name for the dangerous goods as determined in accordance with 3.1.2 and the corresponding UN number, preceded by the letters “UN”, shall be displayed on each package. The UN number and the letters “UN” shall be at least 12 mm high, except for packages of 30 litres capacity or less or of 30 kg maximum net mass or less and for cylinders of 60 litres water capacity or less when they shall be at least 6 mm in height and except for packages of 5 litres or 5 kg or less when they shall be of an appropriate size. In the case of unpackaged articles, the mark shall be displayed on the article, on its cradle or on its handling, storage or launching device. For goods of division 1.4, compatibility group S, the division and compatibility group letter shall also be marked unless the label for 1.4S is displayed. A typical package mark is:
CORROSIVE LIQUID, ACIDIC, ORGANIC, N.O.S. (caprylyl chloride) UN 3265.
Note: Cylinders of 60 L water capacity or less marked with a UN number in accordance with the provisions of the IMDG Code up to 31 December 2013 and which do not conform to the provisions of 188.8.131.52 regarding the size of the UN number and of the letters "UN" applicable as from 1 January 2014 may continue to be used until the next periodic inspection but no later than 1 July 2018.
All package marks required by 184.108.40.206:

- Labelling of packages including IBCs
These provisions are related essentially to danger labels. However, additional marks or symbols indicating precautions to be taken in handling or storing a package (such as a symbol representing an umbrella, indicating that a package shall be kept dry) may be displayed on a package if appropriate.
- Labels identifying primary and subsidiary risks shall conform to models Nos. 1 to 9 illustrated in 18.104.22.168.2. The "EXPLOSIVE" subsidiary risk label is model No. 1.
- Where articles or substances are specifically listed in the Dangerous Goods List, a danger class label shall be affixed for the hazard shown in column 3. A subsidiary risk label shall also be affixed for any risk indicated by a class or division number in column 4 of the Dangerous Goods List. However, special provisions indicated in column 6 may also require a subsidiary risk label where no subsidiary risk is indicated in column 4 or may exempt from the requirement for a subsidiary risk label where such a risk is indicated in the Dangerous Goods List.
A package containing a dangerous substance which has a low degree of danger may be exempt from these labelling requirements. In this case, a special provision specifying that no hazard label is required appears in column 6 of the Dangerous Goods List for the relevant substance. However, for certain substances the package shall be marked with the appropriate text as it appears in the special provision, for example:
Substance Un No. Class Mark required on bales Baled hay in cargo transport unit 1327 4.1 None Baled hay not in cargo transport unit 1327 4.1 Class 4.1 Baled dry vegetable fibres in cargo transport unit 3360 4.1 None Substance Un No. Class Mark required on packages in addition to the Proper Shipping Name and UN number Fishmeal* 1374 4.2 Class 4.2† Batteries, wet, non-spillable 2800 8 Class 8‡
* Only applicable to fishmeal in packing group III.
† Exempt from class marking when loaded in a cargo transport unit containing only fishmeal under UN 1374.
‡ Exempt from class marking when loaded in a cargo transport unit containing only batteries under UN 2800.
- Except as provided in 22.214.171.124.3.1, if a substance which meets the definition of more than one class is not specifically listed by name in the Dangerous Goods List in chapter 3.2, the provisions in chapter 2.0 shall be used to determine the primary risk class of the goods. In addition to the label required for that primary risk class, subsidiary risk labels shall also be applied as specified in the Dangerous Goods List.
- Packagings containing substances of class 8 need not bear subsidiary risk label model No. 6.1 if the toxicity arises solely from the destructive effect on tissue. Substances of class 4.2 need not bear subsidiary risk label model No. 4.1.
Labels for class 2 gases with subsidiary risk(s)
Class Subsidiary risk(s) shown in chapter 2.2 Primary risk label Subsidiary risk label(s) 2.1 None 2.1 None 2.2 None 2.2 None 5.1 2.2 5.1 2.3 None 2.3 None 2.1 2.3 2.1 5.1 2.3 5.1 5.1, 8 2.3 5.1, 8 8 2.3 8 2.1, 8 2.3 2.1, 8
- Three separate labels have been provided for class 2, one for flammable gases of class 2.1 (red), one for non-flammable, non-toxic gases of class 2.2 (green) and one for toxic gases of class 2.3 (white). Where the Dangerous Goods List indicates that a class 2 gas possesses single or multiple subsidiary risks, labels shall be used in accordance with the table in 126.96.36.199.4.
Except as provided in 188.8.131.52.1.2, each label shall:
be located on the same surface of the package near the Proper Shipping Name mark, if the package dimensions are adequate;
be so placed on the packaging that it is not covered or obscured by any part or attachment to the packaging or any other label or mark; and
when primary and subsidiary risk labels are required, be displayed next to each other.
Where a package is of such an irregular shape or small size that a label cannot be satisfactorily affixed, the label may be attached to the package by a securely affixed tag or other suitable means.
- Intermediate bulk containers of more than 450 L capacity and large packagings shall be labelled on two opposing sides.
- Labels shall be affixed on a surface of contrasting colour.
Special provisions for the labelling of self-reactive substances
An "EXPLOSIVE" subsidiary risk label (No.1) shall be applied for type B self-reactive substances, unless the competent authority has permitted this label to be dispensed with for a specific packaging because test data have proved that the self-reactive substance in such a packaging does not exhibit explosive behaviour.
Special provisions for the labelling of organic peroxides
The class 5.2 label (model No. 5.2) shall be affixed to packages containing organic peroxides classified as types B, C, D, E or F. This label also implies that the product may be flammable and hence no "FLAMMABLE LIQUID" subsidiary risk label (model No. 3) is required. In addition, the following subsidiary risk labels shall be applied:
An "EXPLOSIVE" subsidiary risk label (model No. 1) for organic peroxides type B, unless the competent authority has permitted this label to be dispensed with for a specific packaging because test data have proved that the organic peroxide in such a packaging does not exhibit explosive behaviour.
A "CORROSIVE" subsidiary risk label (model No. 8) is required when packing group I or II criteria of class 8 are met.
Special provisions for the labelling of infectious substances packages
In addition to the primary risk label (model No. 6.2), infectious substances packages shall bear any other label required by the nature of the contents.
- Special provisions for the labelling of radioactive material
- Except when enlarged labels are used in accordance with 184.108.40.206.5.1, each package, overpack and freight container containing radioactive material shall bear the labels conforming to the applicable model Nos. 7A, 7B or 7C, according to the appropriate category. Labels shall be affixed to two opposite sides on the outside of the package or overpack or on the outside of all four sides of a freight container or tank. Each overpack containing radioactive material shall bear at least two labels on opposite sides of the outside of the overpack. In addition, each package, overpack and freight container containing fissile material, other than fissile material excepted under the provisions of 220.127.116.11.5, shall bear labels conforming to model No. 7E; such labels, where applicable shall be affixed adjacent to the labels conforming to the applicable model Nos. 7A, 7B or 7C. Labels shall not cover the marks specified in this chapter. Any labels which do not relate to the contents shall be removed or covered.
Each label conforming to the applicable model No. 7A, 7B or 7C shall be completed with the following information:
Except for LSA-I material, the name(s) of the radionuclide(s) as taken from the table under 18.104.22.168.1, using the symbols prescribed therein. For mixtures of radionuclides, the most restrictive nuclides must be listed to the extent the space on the line permits. The group of LSA or SCO shall be shown following the name(s) of the radionuclide(s). The terms "LSA-II", "LSA-III", "SCO-I" and "SCO-II" shall be used for this purpose.
For LSA-I material, the term "LSA-I" is all that is necessary; the name of the radionuclide is not necessary.
Activity: The maximum activity of the radioactive contents during transport, expressed in units of becquerels (Bq) with the appropriate SI prefix symbol (see 22.214.171.124). For fissile material, the total mass of fissile nuclides in units of grams (g), or multiples thereof, may be used in place of activity.
For overpacks and freight containers, the "contents" and "activity" entries on the label shall bear the information required in 126.96.36.199.12.2.1 and 188.8.131.52.12.2.2, respectively, totalled together for the entire contents of the overpack or freight container except that, on labels for overpacks or freight containers containing mixed loads of packages containing different radionuclides, such entries may read "See transport documents".
- Each label conforming to the model No. 7E shall be completed with the criticality safety index (CSI) as stated in the certificate of approval applicable in the countries through or into which the consignment is transported and issued by the competent authority or as specified in 184.108.40.206 or 220.127.116.11.
- For overpacks and freight containers, the label conforming to model No. 7E shall bear the sum of the criticality safety indexes of all the packages contained therein.
- In all cases of international transport of packages requiring competent authority approval of design or shipment, for which different approval types apply in the different countries concerned by the shipment, labelling shall be in accordance with the certificate of the country of origin of design.
- Provisions for labels
Labels shall satisfy the provisions of this section and conform, in terms of colour, symbols, numbers and general format, to the specimen labels shown in 18.104.22.168.2.
Note: Where appropriate, labels in 22.214.171.124.2 are shown with a dotted outer boundary as provided for in 126.96.36.199.1.1. This is not required when the label is applied on a background of contrasting colour.
Labels shall be configured as shown in the figure below:
* The class or, for divisions 5.1 and 5.2, the division number shall be shown in the bottom corner
** Additional text/numbers/symbol/letters shall (if mandatory) or may (if optional) be shown in this bottom half
*** The class or division symbol or, for divisions 1.4, 1.5 and 1.6, the division number, and for Model No. 7E the word "FISSILE" shall be shown in this top half
- Labels shall be displayed on a background of contrasting colour, or shall have either a dotted or solid outer boundary line.
- The label shall be in the form of a square set at an angle of 45° (diamond-shaped). The minimum dimensions shall be 100 mm x 100 mm and the minimum width of the line inside the edge forming the diamond shall be 2 mm. The line inside the edge shall be parallel and 5 mm from the outside of that line to the edge of the label. The line inside the edge on the upper half of the label shall be the same colour as the symbol and the line inside the edge on the lower half of the label shall be the same colour as the class or division number in the bottom corner. Where dimensions are not specified, all features shall be in approximate proportion to those shown.
- If the size of the package so requires the dimensions may be reduced, provided the symbols and other elements of the label remain clearly visible. The line inside the edge shall remain 5 mm to the edge of the label. The minimum width of the line inside the edge shall remain 2 mm. Dimensions for cylinders shall comply with 188.8.131.52.1.2.
Cylinders for class 2 may, on account of their shape, orientation and securing mechanisms for transport, bear labels representative of those specified in this section, which have been reduced in size, according to ISO 7225:2005, for display on the non-cylindrical part (shoulder) of such cylinders. Labels may overlap to the extent provided for by ISO 7225:2005 Gas cylinders - Precautionary labels; however, in all cases, the labels representing the primary hazard and the numbers appearing on any label shall remain fully visible and the symbols recognizable.
Note: When the diameter of the cylinder is too small to permit the display of the reduced size labels on the non-cylindrical upper part of the cylinder, the reduced sized labels may be displayed on the cylindrical part.
- With the exception of labels for divisions 1.4, 1.5 and 1.6 of class 1, the upper half of the label shall contain the pictorial symbol and the lower half shall contain the class number 1, 2, 3, 4, 5.1, 5.2, 6, 7, 8 or 9 as appropriate. The label may include text such as the UN Number, or words describing the hazard class (e.g., "flammable") or for label No. 9A the symbol in accordance with 184.108.40.206.1.5 provided the text does not obscure or detract from the other required label elements.
- In addition, except for divisions 1.4, 1.5 and 1.6, labels for class 1 shall show in the lower half, above the class number, the division number and compatibility group letter for the substance or article. Labels for divisions 1.4, 1.5 and 1.6 shall show in the upper half the division number and in the lower half the class number and the compatibility group letter. For division 1.4, compatibility group S, no label is generally required. However, in cases where a label is considered necessary for such goods, it shall be based on model No. 1.4.
- On labels other than those for material of class 7, the insertion of any text (other than the class or division number) in the space below the symbol shall be confined to particulars indicating the nature of the risk and precautions to be taken in handling. For label No. 9A, no text other than the class mark shall be included in the bottom part of the label.
The symbols, text and numbers shall be shown in black on all labels except for:
the class 8 label, where the text (if any) and class number shall appear in white;
labels with entirely green, red or blue backgrounds, where they may be shown in white;
the class 5.2 label, where the symbol may be shown in white; and
class 2.1 labels displayed on cylinders and gas cartridges for liquefied petroleum gases, where they may be shown in the background colour of the receptacle if adequate contrast is provided.
- The method of affixing the label(s) or applying stencil(s) of label(s) on packages containing dangerous goods shall be such that the label(s) or stencil(s) will still be identifiable on packages surviving at least three months' immersion in the sea. In considering suitable labelling methods, account shall be taken of the durability of the packaging materials used and the surface of the package.
Note: Labels shall satisfy the provisions below and conform, in terms of colour, symbols and general format, to the models shown in 220.127.116.11.2. Corresponding models required for other modes of transport, with minor variations which do not affect the obvious meaning of the label, are also acceptable.
