• IATA sorts the types of dangerous goods and provides 14 different columns of relevant information for air transportation.

The list of dangerous goods in the International Air Transport Association Dangerous Goods Regulations (IATA DGR) is commonly called the “Blue Pages,” since the pages in this section of the print version are blue. The colored pages make this section easily identifiable when looking at the printed DGR from the side. The list, as in all other dangerous goods regulations, is a core section to identify the substances, mixtures, and relevant information in the regulations.

The list of dangerous goods is divided into 14 columns for each of the individual dangerous goods listed. The list is arranged in alphabetical order by the proper shipping name in Column B. To find a material, the carrier must have the proper shipping name.

Column A – UN/ID (United Nations Identification) Number

This column displays the number assigned to the material under the United Nations (UN) Classification System. When this number is used, it must be prefixed by the letters “UN.”

Column B – Proper Shipping Names

This column contains an alphabetical listing of dangerous goods articles and substances, identified by their proper shipping names, together with qualifying descriptive text. The proper shipping name is shown in bold (dark) type, whereas the descriptive text is shown in light type.

Column C – Class or division

This column lists the class or division number assigned to the article or substance. In the case of Class 1 Explosives, the compatibility group is also shown.

Column D – Labels

This column displays the hazard label(s) to be applied to the outside of each package and overpack for the material shown in Column B. The primary hazard label is listed first, followed by any subsidiary risk label(s).

Column E – Packing Group (PG)

This column contains the UN Packing Group (I, II, III) where assigned to the material.

Column F – Excepted Quantity Code

This column lists the excepted quantity code assigned to the material by packing group.

Column G – Passenger and Cargo Aircraft Limited Quantity: Packing Instructions

This column refers to the relevant Limited Quantity (Y) Packing Instructions listed in Section 5 of the IATA DGR for transport of the article or substance on a passenger or on a cargo aircraft. If the word “Forbidden” is shown, the material cannot be carried under Limited Quantity provisions.

Column H – Passenger and Cargo Aircraft Limited Quantity: Maximum Net Quantity per Package

This column shows the maximum net quantity (weight or volume) of the material allowed in each package for transport on a passenger or cargo aircraft. The weight listed is net weight, unless otherwise indicated by a letter “G,” which refers to the gross weight of the package.

Column I – Passenger and Cargo: Packing Instructions

This column refers to the Packing Instructions listed in Section 5 of the IATA DGR for transport of the material on a passenger or on a cargo aircraft.

Column J – Passenger and Cargo Aircraft: Maximum Net Quantity per Package

This column lists the maximum net quantity (weight or volume) of the material allowed in each package for transport on a passenger or cargo aircraft. The maximum quantity per package may be further restricted by the type of container used.

If the word “Forbidden” is shown, the material cannot be carried on a passenger aircraft.

Column K – Cargo Aircraft Only: Packing Instructions

This column refers to the Packing Instructions listed in Section 5 of the IATA DGR for transport of the material on cargo aircraft ONLY.

Column L – Cargo Aircraft Only: Maximum Net Quantity per Package

This column displays the maximum net quantity (weight or volume) of the material allowed in each package for transport on cargo aircraft ONLY. The maximum quantity per package may be further restricted by the type of container used.

If the word “Forbidden” is shown, the material cannot be carried on any aircraft unless exempted.

Column M – Special Provisions

This column may show an alpha-numeric character that relates to Subsection 4.4 of the IATA DGR and applies to all the packing groups permitted for the entry concerned, unless the wording of the special provision makes it otherwise apparent.

Column N – ERG (Emergency Response Guidance) Code

This column provides the Emergency Response Drill Code as found in the International Civil Aviation Organization (ICAO) document “The Emergency Response Guidance for Aircraft Incidents Involving Dangerous Goods.” The code consists of a combination of letters and numbers that represent suggested responses to incidents involving the specific dangerous good entry to which the drill code is assigned.
