The
container
number is
entered on
the bill of
lading to
facilitate
the
identificatio
n and
tracking of
the
container
and the
cargo.
Each container has an
identification code or
container number---a
combination of the 4-letter
characters that identify the
owner (the operator of
container) and the
7-numeric characters that
identify the container. The
container number can be
found on the outer and
inner side walls.
The rating, tare mass and payload of a container is marked on its wall, usually on the end (rear) door in the case of an
end-loading dry cargo container.
The Marking and Identification of
Containers
In exporting,
it is common
to encounter
a payload of
17,500 kgs.
or less in the
20'
container,
and 24,000
kgs. or less
in the 40'
container.
If the tare mass of a 20' dry cargo
container is 2,400 kgs. and a 40'
is 3,900 kgs., the payload of 20' is
21,600 kgs. (i.e., 24,000 kgs.
minus 2,400 kgs.) and 40' is
26,580 kgs. (i.e., 30,480 kgs.
minus 3,900 kgs.). However, the
exporter may be prohibited to
have that much payload in areas
where there are legal limitations to
the overall load of a vehicle.
The tare mass of containers may vary due to the different construction techniques and materials used in the container. A 20' x 8.5' dry
cargo container may weigh
1,800 kgs. to 2,400 kgs., a 40' x 8.5' may weigh 2,800 kgs. to 4,000 kgs, and a 40' x 9.5' may weigh 3,900
kgs.
to 4,200 kgs. Some dry cargo containers may fall outside the indicated weight range. The reefer weighs more than a dry cargo
container of the same size.

Payload

       
Payload is the maximum permitted mass (or weight) of payload, including the dunnage and cargo securement arrangements
that are not associated with the container in its normal operating condition. Therefore,
Payload = Rating - Tare Mass.

Rating

       
Rating is the maximum gross mass (or weight), that is, the maximum permissible weight of a container plus its contents. The
rating of a
20' dry cargo container is 24,000 kgs. (52,900 lbs.), and a 40', including the high cube container, is 30,480 kgs. (67,200
lbs.).
Tare Mass

       
Tare Mass---tare weight or tare---is the mass (or weight) of empty container, including all fittings and appliances used in a
particular type of container in its normal operating condition.
Rating, Tare Mass and Payload of
Containers
The container capacity is the total
cube a container can accommodate.
The term
cube often refers to the
cubic measurement of cargo. The
capacity (i.e., the internal volume)
is determined by multiplying the
internal dimensions, that is, the
product of internal length, width
and height. The capacity may vary
among containers of the same
length and height.
There are half
height
containers

(4.25' or 4' 3"
high) designed
for heavy loads
such as steel
rods and
ingots, which
absorb the
weight limit in
half the normal
space.
The demand
for the
high
cube
container
---hi
cube
---is
increasing.
The popular
high cube
container has
a normal
height of 9.5
feet (9.5' or
9' 6").
The 20 feet (20')
and 40 feet (40')
containers are
very popular in
ocean freight.
The 8.5 feet
(8.5') high
container---8 feet
6 inches (8' 6")
high
container---is
often referred to
as
standard
container
.
