0. INTRODUCTION
This specification provides the definition of the Instruction
message (IFTMIN) to be used in Electronic Data Interchange
(EDI) between trading partners involved in administration,
commerce and transport.
1. SCOPE
This paper provides the definition of the Instruction Message
to be used in fulfilling the requirements of trading partners
in the transport chain worldwide, in the interchange of cargo
and transport related information using Electronic Data
Interchange (EDI).
This message is a single consignment based message, being
aligned with other single consignment based messages such as
the booking messages (IFTMBP, IFTMBF and IFTMBC), the
Instruction Contract Status Message (IFTMCS) and the Arrival
Notice Message (IFTMAN).
The single consignment based messages can be used by all modes
of transport for the forwarding and transport of goods from any
origin to any destination, regardless of route or prevailing
commercial practice.
These messages are suitable for the arrangement of the
transport of goods between all parties to the movement of the
consignment (including the consignor/shipper and consignee as
well as the forwarders, brokers, and carriers involved) as well
as providing the information necessary to perform that
transport and delivery of the goods.
They should be used in the same way by each mode of transport
when the requirements are common even if functionally similar
information is known by different names.
1.1 Functional Definition
A message from the party issuing an instruction regarding
forwarding/transport services for a consignment under
conditions agreed, to the party arranging the forwarding and/or
transport services.
1.2 Field of Application
The Instruction message may be used for both national and
international applications. It is based on universal practice
related to administration, commerce and transport, and is not
dependent on the type of business or industry.
1.3 Principles
The instruction results in a transport contract for a
consignment and is primarily meant for administrative purposes.
It will be the message from shipper to carrier or forwarder
containing the final details of the consignment for which
services are provided. The instruction message is the one and
only message which results in the actual contract which can
either be a document or an electronic contract.
If only one message will suffice in an exchange between a
shipper and a carrier/forwarder the instruction message should
be the one as this message is the only message that results in
a contract. The receiving party is to ascertain whether the
Instruction message is preceded by a Booking Firm message, to
be able to interpret the function as being an administrative
message only or an administrative and operational message.
- A consignment may contain several goods items.
- Goods items may or may not be containerized.
- A goods item may be transported in one or more containers,
and a single container may contain one or more goods items.
- One goods item may be related to one or more customs tariff
codes.
- Goods items related to one customs tariff code may be carried
in one or more containers.
- Goods items may reflect either the contractual or operational
description of the goods.
- A party to the movement of the consignment may book or order
transport for one or more goods items.
- A party to the movement of the consignment may book or issue
instructions of transport to be arranged for several goods
items by means of one or several of the following messages:
IFTMBP, IFTMBF, IFTMBC, IFTMIN, IFTMCS, IFTMAN.
- Pre-carriage (advanced haulage) and/or on-carriage
(destination haulage) of goods items or equipment within one
booking or instruction may take place in different steps, each
step specified with its own transport details group.
- Equipment may have other types of equipment attached to it,
e.g. a temperature control unit attached to a container.
- Equipment and/or goods items may be attached to or
transported on another load or transport device, which as such
may be attached to or transported on yet another load or
transport device, e.g. a container on a chassis on a rail-car.
- Transport devices, which have the ability of powered movement
on their own, are specified in the transport details group.
Other load or transport devices are specified as equipment.
- The expression of packaging for goods items can be expressed
at up to three levels.
A number of generic transport terms are used in this
specification, to be described as:
* MODE OF TRANSPORT: The method of transport used for the
conveyance of goods or persons, e.g. by rail, by road, by sea.
* MEANS OF TRANSPORT: The vehicle used for the transport of
goods or persons, e.g. aircraft, truck, vessel.
* TYPE OF MEANS OF TRANSPORT: The type of vehicle used in the
transport process, e.g. wide body, tank truck, passenger
vessel.
* EQUIPMENT: Material resources necessary to facilitate the
transport and handling of cargo. Transport equipment does under
the given circumstances not have the ability to move by its own
propulsion (e.g. sea container, trailer, unit load device,
pallet).
* TYPE OF EQUIPMENT: The type of material used, e.g. 40 feet
container, four way pallet, mafi trailer.
