Objectives
• Determine proper shipping names and UN
numbers for Dangerous Goods
• Use the Dangerous Goods List to find:
– Proper shipping names and UN numbers
– Hazard classes and divisions
– Labels
– Packing groups
– Special provisions
– Packing instructions
– Net quantities allowed

Section 4 of the IATA DGR is
divided into 4 Sub-sections
4.1 Proper Shipping Name
4.2 List of Dangerous Goods
4.3 Numerical Cross-Reference List
4.4 Special Provisions

Identification by
Proper Shipping Name
• Each dangerous good has
a proper shipping name
(PSN) that identifies it
• PSN’s will be marked on
packages and entered on
transport documents
Amyl Nitrate
Hi, My Name Is

• PSN’s will be marked
on packages and
entered on transport
documents
• Rules for PSN’s can
be found in 4.2

Identification: UN Number
• Like the PSN, a UN number is
used to identify a particular
dangerous goods
• It will also be used as a marking
and shipping paper entry
• Alphabetical by name
• ICAO assigns “ID” numbers to
items that do not yet have a UN
number. They are in the 8000’s
(“ID 8000”) & new (“ID 8001”)
UN 1112

HOW TO USE THE LIST OF
DANGEROUS GOODS
* Selection the proper shipping name
* Items listed by name
* Item not listed by name

M. Tayfour 40
Selection the proper
shipping name
Dangerous goods must be
assigned to one of the proper
shipping name shown in the
list of IATA DGR section 4.2

M. Tayfour 41
Items listed by name
The following apply when
articles or substances are
listed by name.

Items listed by name
M. Tayfour 42

M. Tayfour 43
Some UN numbers have several
acceptable proper shipping names.
Examples: UN 1203 and UN 1950
Example 1: UN 1203

M. Tayfour 44
The proper shipping name for UN 1203 is,
therefore, either: Gasoline, Motor Spirit or Petrol.

M. Tayfour 45
UN 1950 is the UN number for 17
different types of Aerosols.

Some articles and substances are
listed with more than one UN number
M. Tayfour 46

M. Tayfour 47
Items not listed by name
You must not interpret the
absence of an article or
substance from the list as
either permitting or not
permitting its transport by air.

M. Tayfour 48
When assigning the proper
shipping name for an item not
listed by name, select the
entry which most accurately
describes that item

M. Tayfour 49
• If the item is not forbidden, classify it by
comparing its properties with the
classification criteria describe in section 3.
• There are two types of generic or n.o.s.
proper shipping names: specific n.o.s. and
general n.o.s. entries;
• The specific n.o.s. entries cover a group of
substances or articles of a particular
chemical or technical nature. For example:
Alcohols, n.o.s.

M. Tayfour 50
• The general n.o.s. entries apply to a group of
substances or articles meeting the criteria of one
or more classes or divisions. E.g. Corrosive
solid, n.o.s.
• If available, use the specific n.o.s. entry in
preference to the generic n.o.s.
• Where there is ANY doubt as to whether a non-
listed article or substance is permitted for
transport by air, or under what conditions, the
shipper and/or operator must consult the
appropriate national authority.

M. Tayfour 51
The symbol in the List of
Dangerous Goods identifies those
proper shipping names which
require the addition of a technical
name. The symbol is not part of the
proper shipping name.

An extract from Table 4.1.A

M. Tayfour 55
How to allocate Proper Shipping Name & UN Number
Example 1 – (Specific Entries)
Methyl propanoate, is an Ether with a flash point of -2°C and an initial boiling point of
80oC and is not listed in IATA DGR 4.2
STEP 1 Determine the characteristics of the substance (using Material Safety
Data Sheet (MSDS), test results, flash point, boiling point etc.) Flash
point -2°C; initial boiling point 80°C
STEP 2 Check if forbidden: According to IATA DGR 2.1.1 and 4.2 – (Not
forbidden)
STEP 3 Classify the substance: Class 3 Packing Group II
STEP 4 Assign the proper shipping name that most accurately describes the
substance using Table 4.1.A

M. Tayfour 56
“
“ ” is not part of proper shipping name therefore, must not be shown
when using the proper shipping name i.e. documentation and marking.

• Technical name is required to be
supplemented in brackets
Proper Shipping Name: Ethers, n.o.s.
(Methyl propanoate) rather than hazard
name: Flammable liquid, n.o.s. (Methyl
propanoate).

2. Methyl-n-amyl carbinol, an alcohol with a flashpoint of 54oC
is not listed by name. What is the appropriate proper shipping
name?
Alcohol, n.o.s. (Methyl-n-amyl carbinol)
3. 2-Methylpropanal is an aldehyde with a flash point of 58°C
and an initial oiling point of 87°C. What is the appropriate
proper shipping name, Packing Group and UN number?
Aldehyde, n.o.s (2-Methylpropanal); PGIII; UN1989

M. Tayfour 61
Example 2 – (General Entries)
A liquid has a chemical name “Shams” is having corrosive with an
exposure time of 5 min. and an observation time of 3 days. What is
the proper shipping name, UN Number and the Packing Group
assignment for this substance?
STEP 1 Check characteristics:
Exposure time: 5min; Observation time: 3days
STEP 2 Check if forbidden:
According to IATA DGR 2.1.1 and 4.2
STEP 3 Classify the substance:
Using Table 3.8.A to determine corrosives packing group assignment: Class 8, II
STEP 4 Sign the proper shipping name that describes the substance most
accurately

M. Tayfour 62
Therefore:

Mixtures and Solutions with Single Hazard
A mixture or solution containing a substance Listed by name in the List of
Dangerous Goods (IATA DGR 4.2) mixed with one or more Substances not
subject to these Regulations Must be identified by the listed proper shipping
Name. The qualifying words “mixture” or “Solution” must be added, e.g.
Lead cyanide Mixture. The concentration of the mixture or Solution may be
added.
Example: Acetone 75% solution.
The proper shipping name of a mixture for
which the above mentioned exception applies is
the appropriate n.o.s. entry plus the technical
name in parentheses. The words “mixture” or
solution must be added, e.g. Toxic solid,
inorganic n.o.s. (Lead cyanide mixture).
Proper shipping Name of a Mixture or
Solution where the Degree of Hazard
Remains Unchanged

M. Tayfour 64
Example: The hazardous constituent in a mixture is Acetal. (Check the List of
Dangerous Goods for the packing group.)
Based on tests, the same Packing Group II has been established as for the pure
substance. Since neither hazard class nor the packing group has changed and there is no
significant change in the measures to be taken in emergencies, the proper shipping
name will be:
Acetal solution (UN 1088, Class 3, Packing Group II) or Acetal 80% solution (UN
1088, Class 3, Packing Group II).
Note:
“Mixture” means a material composed of more than one chemical compound or
element.
“Solution” means any homogeneous liquid mixture of two or more chemical
compounds or element that will not undergo any segregation under conditions normal
to transportation.

M. Tayfour 65
Proper Shipping Name of a Mixture or Solution where the Degree of Hazard
Differs from that Shown in the List of Dangerous Goods
Example: Acetal is again the hazardous constituent in a mixture. But now, based on
tests, Packing Group III has been established for this mixture. The hazard class remains
the same, but as there is a change in the packing group, the proper shipping name will
be (DGR
4.1.3.1):
Flammable liquid, n.o.s. (Acetal) (UN 1993, Class 3, Packing Group III)
or Flammable liquid, n.o.s. (Acetal solution) (UN1993, Packing Group III)
or Flammable liquid, n.o.s. (containing Acetal) (UN1993, Packing Group III)
Note:
If the Acetal is mixed with such a large solution of a substance which is not subject to
these Regulations, that it no longer meets the criteria of Class 3 Flammable Liquid, or
the criteria of any other class.
It is no longer classified as dangerous goods, and the words “Not Restricted” should
be shown on the air waybill. DGR 4.1.3.2.

M. Tayfour 66

Mixtures or Solutions containing two or
more Dangerous Substances
When two dangerous goods are mixed together it has
constituents of two or more different hazards. It is the
shipper’s responsibility to assign a Proper Shipping Name
based on Table 3.10.A and 4.1.A
Example: The item Engine cleaning mixture has two
constituents with different hazards. It consists of Gasoline and
Carbon tetrachloride.
The mixture, after tests, is found to meet the criteria of Class
3, Packing Group II and Division 6.1, Packing Group II.

M. Tayfour 74
Mixtures or Solutions containing two or
more Dangerous Substances
According to IATA DGR Table 3.10.A the
Primary Hazard is Class 3, Flammable
liquid and therefore the Subsidiary hazard
is Division 6.1, Toxic Substance. The
applicable Packing Group is II. The Proper
Shipping name and the UN Number are
Flammable liquid, toxic, n.o.s.
(Gasoline and Carbon tetrachloride
solution) UN1992.

M. Tayfour 75

Summary
• Subsection 4.3 is used as a cross reference to
locate UN Number
• Subsection 4.1 is used to select generic or
n.o.s. names and entries for articles/substances
that are not specifically listed in Subsection 4.2
• Where article/substance is not specifically listed
by name in Subsection 4.2 and has two
hazards, the primary hazard must be
determined in accordance with the criteria
presented in Subsection 3.10.
