1.3.1 IATA AREAS & SUB-AREAS
TACT Rules, section 1.2.2, definitions of areas. When
creating the rules governing fares and rates and their
application, IATA Airline found it convenient to consider the
world in 3 main IATA area and several sub areas contained
within these 3 area.
These IATA areas and sub-areas are of particular importance.
However they do not always coincide with the accepted
TACT rules, section 1.2.2, definitions of areas, explain these
boundaries which are also shown on the IATA map
reproduced on the previous page.
This section should be consulted whenever you have any doubt
about the precise meaning of any definitions used in the tariff.
A. IATA AREAS.
The main IATA Areas are:
IATA AREA 1
- All of the north and south American continents and
the adjacent islands
- Central America
- Bermuda and Greenland
- The west Indies and the islands of the Caribbean sea.
- The Hawaiian islands including Midway and
IATA AREA 2
Europe( including the European part of the
Russian Federation( former USSR) west of
All of African and the adjacent islands.
That part of Asia lying west of and including
IATA AEA 3
All of Asia east of Iran and the adjacent Islands.
The east Indies
Australia and New Zealand and the adjacent islands
The islands of the pacific ocean except those
included in Area 1.
B IATA SUB-AREAS
IATA areas have been further divided into smaller sub-
areas or regions:
IATA AREA 2 SUB-AREAS
Europe, Africa, Middle East
IATA AREA 3 SUB-AREAS
-South Asian sub continent south east Asia,
south west pacific, Japan / Korea.
These sub-areas, in the IATA context, may have
a different meaning from that generally
implied by the geographical term.
The IATA definition of Europe comprises not only geographical
Europe but includes also the following countries, parts of
countries and islands.
- 3 North African countries ie Morocco, Algeria and Tunisia.
- The Azores, Madeira and the canary islands
- The Asian part of Turkey
Thus, cities like Casablanca, Algiers, Tunis, Las Palmas and
Ankara are all situated within in the IATA Europe sub- Area
2. Although geographically Egypt and Sudan are situated on the
African continent, these countries are included in the IATA
middle East sub area. SO is Cyprus
1.4 CHARGEABLE WEIGHT
TACT rules, section 3.9.3, chargeable weight
The chargeable weight can be
- The gross weight of the shipment
- The volume weight of the shipment or
- The minimum weight of a rate, whichever is higher.
The gross weight and volume weight are explained on the next
The minimum weight published together with certain rate
categories will be explained later in this course
The chargeable weight must always be shown on the airway bill.
1.4.1GROSS WEIGHT ( HIGH
The gross weight is used as the chargeable weight in
the case of cargo which is heavy in relation to its
volume such s gold, machinery, metal parts etc. This
type of cargo is called HIGH DENSITY CARGO.
HIGH DENSITY CARGO is cargo which weighs equal
or more than 166.666 kgs per m3 or
1kg per 6000cm3, or
1kg per 366 cu. In, or
1ib per 166 cu.in
1.4.2 VOLUME WEIGHT (LOW
TACT rule , section 3.9.4, volume weight incase of cargo which is bulky in
relation to its weight, such as hats, woolen pullovers, etc, the chargeable
weight will be established on the basis of volume rather than gross weight.
The Volume Weight will be calculated and used as the chargeable weight. This
type of cargo is called LOW DENSITY CARGO.
Low Density Cargo is cargo which weighs less than 166.666 kgs per m3 or
1kg per 6000cm3.or
1 kg per 366 cu.in or
1 ib per 166 cu.in
From a few countries in IATA area 3, for all or
for specified commodities, th3 volume weight
is to be calculated with 7000 cm3 for 1 kg.
f) TACT RULES
3.9.4 volume weight
a) From Taiwan (all countries)
b) From Sri Lanka for SCR items 1024, 1401
and 2203 the formula 7000 cubic cms equals
1 kg applies
The chargeable weight must be
rounded up as follows:
KG: WHEN THE CHARGEABLE WEIGHT
IS EXPRESSED IN KILOGRAMS, HALF
OR LARGER FRACTIONS OF A
KILOGRAM ( 0.501 TO 0.999KGS MUST
BE ROUNDED UP RO THE NEXT
HIGHER FULL KILOGRAM
LB: WHEN THE CHARGEABLE WEIGHTS
IS EXPRESSED IN POUNDS, FRACTIONS
OF A POUND MUST BE ROUNDED UP
TO THE NEXT HIGHER FULL LB
Volume/ gross weight 100.2kgs= chargeable weight 100.5kgs
Volume/ gross weight 100.8 kgs= chargeable weight 101kgs
Volume/ gross weight 100 1bs 2 ounces= chargeable weight
Volume/ gross weight 100 ibs 7 ounces= chargeable weight is
Note: A calculated volume weight of 0.501.kgs,0.001kg or
0.001 ib must be rounded up to the next higher full, half kg or
higher full pound respectively
A volume weight of 318.001 kgs muyst be
rounded up to 318.5 kgs.
A volume weight of 262.002 kgs must be
rounded up to 262.5 kgs.
A volume weight of 1669.001 ibs must be
rounded up to 1670 I bs
Avolume weight of 2369.002 ibs must be
rounded up to 2370 ibs.
1.4.3 Establishing the chargeable
Reference, TACT rules, section 3.9.4 volume
weight. The following calculations must be
made in order to determine the volume
weight of one or several pieces of cargo.
A. Consignments of one place
STEP 1; Measure the piece along its:
Greatest Length, greatest width and greatest
Height regardless of its geometric shape.
For a drum measuring 60cm
in diameter with a height of
To calculate the volume of a drum the diameter
should be treated as length and width.
STEP 2 Round off dimensions as
Half or larger fraction of a centimeter (0.5-0.9cm) must
be rounded up to the next higher whole centimeter.
A smaller fraction (0.1-0.4 cm) must be rounded down
to next lower whole centimeter .
Example: One piece measuring
140.3cm x 126.5cm x 100.6 cm
=140cm x 127cm x 101cm.
Half or larger fraction of an inch(1/2, 5/8, ¾, 7/8
IN) must be rounded up to the next higher
A smaller fraction (1/8, ¼, 3/8 in) shall be
rounded down to the next lower inch.
One piece measuring 451/8 in 52 ½ in 60 ¾
= 45 x 53 x 61 in.
Multiply rounded-off measurements in order
to obtain the volume of the piece.
140 x 127 x 101cm= 1795780 cm3
45 x 53 x 61 in = 145485 cu.in
The limit between high and low density cargo being:
6000cm3 per kg or 366cu.in per kg or 166 CU.IN
The volume weight is established by dividing the
volume of the piece by the appropriate factor, ie
-if the weight is given in kg and volume in cm3-divide
-if the weight is given in kg and volume in CU.IN –
divide by 366
-if the weight is given in LB and volume in CU.IN –
divide by 166
THE VOLUME WEIGHT SHALL BE
CALCULATED UP TO THREE DECIMAL
PLACES BEFORE ROUNDING OFF.
1795780cm3: 6000=volume weight 299.000kgs
145485cu.in:366=volume weight 398.000kgs
145485 cu.IN: 166=volume weight 876.000kgs.
One piece measuring 150cm x126cm x 101 cm
- 75 in x 66 in x 56 in = 277200cu.in
Hence volume weight
i) 1908900cm3: 6000 = 318.150 kgs
ii) 277200 cu.in: 366 = 757.377 kgs
For pounds. 277200 cu.in 166= 1669.879 ibs
STEP 5. Round off volume weight in
the same manner as gross weight
200.001 kgs = 200.5 kgs
418.250 kgs= 418.5 kgs
498.0011bs = 499ibs
629.472 kgs= 629.5 kgs
2693.829ibs= 2694 ibs.
B. Consignments of two or more
A consignment may consist of several pieces representing both
high and low density cargo if the entire consignment is to be
charged at the same rate then the chargeable weight will be
the total gross weight or the total volume weight, whichever
2 packages sent as one consignment:
Gross weight Dimension
Package A; 1 box 30kgs 90x50x70cm
Package B: 1drum 40kgs Diameter 50cm;
Establish the total volume weight of the entire
consignment and round it off if necessary ie
In this example the total volume weight 86kgs is higher
than the total gross weight and will be therefore
chargeable weight for this shipment.
Total gross weight: 70kgs.
Total volume weight: 86kgs.
Total volume weight: 86kgs.
The possibility of shipping both high and low
density cargo as one consignment charged at
the same rate, constitutes a saving for the
shipper and a source of income for a
consolidator for instance, if the two packages
above had to be sent as two individual
consignments, the following chargeable
weights would apply.
Gross weight = 30kgs
Volume weight = 315000cm3: 6000=52.5kgs
Chargeable weight=volume weight =62.5kgs
Gross weight = 40kgs
Volume weight =200000cm3:6000=33.333kgs rounded up to
Chargeable weight= gross weight = 40kgs
Total A+B: chargeable weight = 92.5kgs.
Hence 6.5kgs more than their combined chargeable weight
Ref. TACT Rules, section 3.9.3
Low density cargo high density cargo
6000cm3< 1 kg 6000cm3=or > 1kg
366 cu.in < 1kg 366cu.in = or > 1kg
166 cu.in < 1 kg 166 cu.in = or >1kg

1.5 MINIMUM CHARGE
Reference: TACT Rules, section 3.4, minimum
The weight charges of a consignment, calculated
by multiplying the chargeable weight by the
applicable rate per KG or per LB may never
be lower than the published minimum charge
from the point of origin to the point of
destination of the shipment.
The level of the minimum charge depends on the IATA
Area with in or between which transportation takes
place and is indicated on the rate line, immediately
after the name of the destination city, with
designator M( minimum) in the min. weight column.

1.6 General Cargo Rates
TACT rules, sections 3.1.b and 3.5, general cargo rates.
General cargo rates ( GCR) apply for commodities for
which there are no specific rates( specific
commodity and class rates) available.
Note that special rates are not offered between every
point of origin and destination
General Cargo Rates
b. General cargo rates( GCR)
General cargo rates apply for the carriage of
commodities in general. The normal general cargo
rates published apply to consignments up to 100kgs.
Lower GCR are available for consignments weighing
more and in many areas of the world further reduced
rates are published for consignments In higher
GCR are published in TACT rates books, section
4, between the points of origin and destination
for consignments weighing.
Less than 45kgs/100LBS= Normal GCR (GCR
More than 45kgs/100LBS= Quantity GCR (GCR
CAIRNS QL AU CNS
AUSTRALIAN & AUD KGS
ABERDEEN GB M 70.00
Normal N N 15.65
The quantity general cargo rates ( GCR Q) are
published with their applicable minimum weight
shown alongside, e.g 45kg, 100kgs, 250kgs etc
From some countries the over 45kgs GCR
( GCR Q 45kg) have been abolished. The next
rate with a higher minimum weight but a
lower rate, is the over 100kgs GCR
( GCR Q 100kgs).
No other minimum weights are available
between the normal GCR ( GCR N) and the
100kgs general cargo rate ( GCR Q 100Kgs)
This means that the NGCR from these countries
is applicable for consignments weighing up to
100kgs and can therefore be called the 100kgs
general cargo rate ( GCR N).
3.5.2 Normal General Cargo Rates
The normal general cargo rate is the under 45 kgs rate
or where no under 45 kgs rate exists, the under
For most countries, the NGCR is applicable to
consignments of less than 45 kgs. For some
countries, however, the NGCR will apply to
consignments up to 100kgs.
For rating purposes in the absence of a normal under 45
kgs GCR, the under 100kgs GCR must be applied.
