Freight containers - Coding, identification and marking (ISO 6346:2022, Corrected version 2022-08)
This document provides a system for the identification and presentation of information about freight containers. The identification system is intended for general application, for example in documentation, control and communications (including automatic data processing systems), as well as for display on the containers themselves.
The methods of displaying identification and certain other data (including operational data) on containers by means of permanent marks are included.
This document specifies:
a) a container identification system, with an associated system for verifying the accuracy of its use, having:
— mandatory marks for the presentation of the identification system for visual interpretation, and
— features to be used in optional Automatic Equipment Identification (AEI) and electronic data interchange (EDI);
b) a coding system for data on container size and type, with corresponding marks for their display;
c) operational marks, both mandatory and optional;
d) physical presentation of marks on the container.
The terms “mandatory” and “optional” in this document are used to differentiate those ISO marking provisions which shall necessarily be fulfilled by all containers from those which are not required of all containers. The optional marks are included to further comprehension and promote uniform application of the optional mark. If a choice has been made to display an optional mark, the provisions laid down in this document relating to the mark shall be applied. The terms “mandatory” and “optional” do not refer to requirements of any regulatory body.
This document applies to all freight containers covered by International Standards ISO 668, parts 1 to 5 of ISO 1496, ISO 8323 and should, wherever appropriate and practicable, be applied:
— to containers other than those covered by the International Standards mentioned in Clause 2;
— to container-related and/or detachable equipment.
NOTE 1 Containers marked according to previous editions of ISO 6346 need not be re-marked.
This document does not cover temporary operational marks of any kind, permanent marks, data plates, etc. which may be required by intergovernmental agreements, national legislation or nongovernmental organizations.
NOTE 2 Some of the major international conventions whose container-marking requirements are not covered in this document are as follows:
— International Convention for Safe Containers (1972, as amended) (CSC), International Maritime Organization (IMO);
— Customs Convention on Containers 1956 and 1972, related to temporary admission and transport under customs seal.
— Convention on Temporary Admission (Istanbul, 26 June 1990), related to temporary admission.
It should not be assumed that this list is exhaustive.
This document does not cover the display of technical data on tank containers (see ISO 1496-3), nor does it, in any way, include identification marks or safety signs for items of cargo which may be carried in freight containers.

Conteneurs pour le transport de marchandises - Codage, identification et marquage (ISO 6346:2022, Version corrigée 2022-08)
Le présent document fournit un système pour l’identification et la présentation d’informations relatives aux conteneurs pour le transport de marchandises. Le système d’identification est prévu pour une application générale (par exemple, pour la documentation, le contrôle et les communications, y compris les systèmes de traitement automatique des données) ainsi que pour le marquage sur les conteneurs eux-mêmes.
Les méthodes d’inscription de l’identification et de certaines autres informations (y compris les données opérationnelles) sur les conteneurs, au moyen de marques permanentes, sont incluses.
Le présent document spécifie:
a) un système d’identification des conteneurs incluant un dispositif pour vérifier l’exactitude de son utilisation, avec:
— des marques obligatoires pour la présentation du système d’identification aux fins d’interprétation visuelle, et
— des éléments à utiliser pour l’identification (facultative) automatique des équipements (AEI) et l’échange électronique de données (EDI);
b) un système de codage des données relatives aux dimensions et au type de conteneur, et les marques correspondantes à inscrire;
c) des marques, obligatoires et facultatives, relatives à l’exploitation;
d) une présentation physique des marques sur le conteneur.
Dans le présent document, les termes «obligatoires» et «facultatifs» sont utilisés pour différencier les dispositions relatives au marquage ISO, qui doivent nécessairement être respectées pour tous les conteneurs, des dispositions qui ne sont pas exigées pour tous les conteneurs. Les marques facultatives sont incluses pour faciliter la compréhension et encourager une application uniforme de ces marques. S’il a été décidé d’inscrire une marque facultative, les dispositions spécifiées dans le présent document relatives à cette marque s’appliquent. Les termes «obligatoire» et «facultatif» ne font pas référence aux exigences d’organismes de réglementation.
Le présent document s’applique à tous les conteneurs pour le transport de marchandises couverts par les Normes internationales ISO 668, ISO 1496 (Parties 1 à 5) et ISO 8323. À chaque fois que cela est approprié et possible, il convient qu’il s’applique:
— aux conteneurs autres que ceux couverts par les Normes internationales mentionnées à l’Article 2;
— aux équipements de conteneurs et/ou aux équipements amovibles.
NOTE 1 Il n’est pas nécessaire de marquer à nouveau les conteneurs déjà marqués conformément aux éditions précédentes de l’ISO 6346.
Le présent document ne couvre pas les marques temporaires relatives à l’exploitation (quel que soit leur type), les marques permanentes, les plaques d’identification, etc., qui peuvent être requises par des accords intergouvernementaux, par la législation nationale ou par des organisations non gouvernementales.
NOTE 2 Certaines des principales conventions internationales dont les exigences de marquage des conteneurs ne sont pas couvertes par le présent document sont indiquées ci-après:
— Convention internationale sur la sécurité des conteneurs (1972, telle qu’amendée) (CSC), Organisation maritime internationale (OMI);
— Convention douanière relative aux conteneurs (1956 et 1972), relative aux admissions temporaires et au transport sous scellement douanier;
— Convention relative à l’admission temporaire (Istanbul, 26 juin 1990), relative aux admissions temporaires.
Il convient de ne pas considérer cette liste comme exhaustive.

Tovorni zabojnik - Kodiranje, identifikacija in označevanje (ISO 6346:2022, popravljena različica 2022-08)
1.1 Ta dokument zagotavlja sistem za identifikacijo in predstavitev informacij o tovornih zabojnikih. Ta sistem za identifikacijo je namenjen splošni uporabi, npr. pri dokumentaciji, nadzoru in komunikaciji (vključno z avtomatskimi sistemi za obdelavo podatkov), in za prikaz na samih zabojnikih.
Vključene so metode prikazovanja identifikacijskih in nekaterih drugih podatkov (vključno s podatki o delovanju) s trajnimi oznakami na zabojnikih.
1.2 Ta dokument določa:
a) sistem za identifikacijo zabojnikov in s tem povezan sistem za preverjanje pravilnosti njihove uporabe, ki zajema:
– obvezne oznake za predstavitev identifikacijskega sistema za vizualno interpretacijo
in
– lastnosti za uporabo pri neobvezni samodejni identifikaciji opreme (AEI) in elektronski izmenjavi podatkov
(EDI);
b) sistem kodiranja podatkov o velikosti in vrsti zabojnika s pripadajočimi oznakami za njun prikaz;
c) oznake o delovanju, tako obvezne kot neobvezne;
d) fizičen prikaz oznak na zabojniku.
1.3 Izraza »obvezen« in »neobvezen« se v tem dokumentu uporabljata za razlikovanje med
določili standardov ISO glede označevanja, ki jih morajo obvezno izpolnjevati vsi zabojniki, in določili, ki niso obvezna za vse zabojnike. Neobvezne oznake so vključene z namenom zagotavljanja dodatnih informacij in spodbujanja k enotni namestitvi neobveznih oznak. V primeru odločitve, da bo prikazana neobvezna oznaka, je treba uporabiti določila tega dokumenta, ki se navezujejo na tako oznako. Izraza »obvezen« in »neobvezen« se ne navezujeta na zahteve nobenega regulativnega organa.
1.4 Ta dokument se uporablja za vse tovorne zabojnike, ki jih obravnavajo mednarodni standardi ISO 668, deli od 1 do 5 standarda ISO 1496 in standard ISO 8323, priporočljivo pa ga je uporabiti (kadar je to primerno in izvedljivo) za:
– zabojnike, ki jih ne obravnavajo mednarodni standardi, navedeni v točki 2;
– opremo, povezano z zabojniki, in/ali snemljivo opremo.
OPOMBA 1: Zabojnikov, označenih v skladu s prejšnjimi izdajami standarda ISO 6346, ni treba ponovno označiti.
1.5 Ta dokument ne obravnava morebitnih začasnih oznak o delovanju, trajnih oznak,
napisnih ploščic itd., ki jih morda zahtevajo medvladni sporazumi, nacionalna zakonodaja ali nevladne organizacije.
OPOMBA 2: Pomembne mednarodne konvencije, katerih zahteve glede označevanja zabojnikov niso zajete v tem dokumentu, so med drugimi:
– Mednarodna konvencija o varnosti zabojnikov (CSC) (iz leta 1972, kot je bila spremenjena), Mednarodna pomorska organizacija (IMO);
– Carinska konvencija o zabojnikih iz leta 1956 in leta 1972 v zvezi z začasnim uvozom in prevozom pod carinsko oznako;
– Konvencija o začasnem uvozu (Istanbul, 26. junij 1990) v zvezi z začasnim uvozom.
Ta seznam se naj ne obravnava kot izčrpen.
Ta dokument ne obravnava prikaza tehničnih podatkov na cisternah-zabojnikih (glej standard ISO 1496-3), niti ne vključuje identifikacijskih oznak ali varnostnih znakov za kose tovora, ki jih lahko vsebujejo tovorni zabojniki.

human eye.
5 Size and type codes and their associated marks
5.1 Purpose
The type and main external dimensions of the container shall be identified with codes marked on the
container. Only those freight containers which conform with both the ISO top-handling capability and
structural stacking requirements set forth in ISO 1496 shall be marked with size and type codes in
accordance with 5.2.2 and 5.2.3.
5.2 Size and type codes
5.2.1 General
This information is mandatory for the marking of containers covered by the International Standards
listed in Clause 2 and shall be coded as in 5.2.2 and 5.2.3.
The size and type codes, when displayed on the container, shall be used as a whole, i.e., the information
must not be broken into its component parts.
The size and type codes shall be displayed in accordance with Clause 7.
5.2.2 Size: two alphanumeric characters
Reference (5) in Figures 1 to 4
ISO 6346:2022(E)
The container size (i.e. external dimensions) shall be indicated by two characters as follows:
— First character: numeric or alphabetic character representing the length.
— Second character: numeric or alphabetic character representing the width and the height.
These two characters shall be determined in accordance with Annex D.
5.2.3 Type: two characters
Reference (6) in Figures 1 to 4
The container type and main characteristics shall be indicated by two characters as follows:
— First character: alphabetic character representing the container type.
— Second character: numeric or alphabetic character representing main characteristics related to the
container type.
These two characters shall be selected in accordance with Annex E.
NOTE For the purpose of exchanging data when indication of the main characteristics is not essential, the
“type group code designation” as shown in Annex E can be used.
6 Operational marks
6.1 General
The marks in this section are not intended to correspond to any particular code (e.g., for use in data
transmission or any other purpose). They are solely intended as markings for use on freight containers
to convey certain information or give visual warnings.
6.2 Mandatory operational marks
6.2.1 Maximum gross and tare masses
The maximum gross and tare masses shall be marked on a container as:
MAX GROSS 00 000 kg
00 000 lb
TARE 00 000 kg
00 000 lb
For safety reasons, containers tested in conformance with the approved methods specified in that part
of ISO 1496 applicable to the type of container in question, i.e., parts 1, 2, 3, 4 or 5 of ISO 1496, shall be
uniformly marked with the maximum gross mass used for those tests.
Furthermore, the “maximum gross mass” marked on the container in accordance with this document
shall be identical to that shown on the CSC Safety Approval Plate.
As indicated above, the masses shall be expressed in both kilograms (kg) and pounds (lb).
NOTE 1 kg = 2 204 lb.
6.2.2 Air/surface container symbol
All air/surface containers shall display the symbol specified in Annex B.
ISO 6346:2022(E)
6.2.3 Warning sign of overhead electrical danger
All containers equipped with ladders shall display a warning sign in accordance with the details given
in Annex C.
6.2.4 Height mark for containers higher than 2,6 m (8 ft 6 in)
All containers higher than 2,6 m (8 ft 6 in) shall bear the following mandatory marks:
a) on both sides, a height mark similar to that described in Annex F;
b) an area of alternating black and yellow stripes on the top members of each end frame and side wall
at each corner adjacent to the corner fitting, of 300 mm (12 in) minimum length, that can be seen
from the ground or from the top. See Figure 5.
In addition, any other optional marks, such as a mirror image of the mark described in Annex F, may be
displayed at any convenient location (e.g., front wall).
6.2.5 Width mark for containers with an overall width greater than 2 438 m (8 ft).
All containers with an overall width greater than 2 438 m (8 ft) shall bear a mark similar to that
described in Annex G on the ends and the roof at both ends.
Where there is insufficient space to fit the marking on the ends or the roof, for example on tank
containers, the marking shall be as wide as is practicable on the ends and may be omitted on the roof.
6.3 Optional operational mark (maximum mass of payload)
It is common industry practice to mark containers with maximum payload in addition to the maximum
gross and tare masses.
If used, the maximum mass of payload should be marked on a container in accordance with the
requirements of 6.2.1, positioned after the maximum gross and tare masses as follows:

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

INTERNATIONAL STANDARD ISO 6346:2022(E)
Freight containers — Coding, identification and marking
1 Scope
1.1 This document provides a system for the identification and presentation of information about
freight containers. The identification system is intended for general application, for example in
documentation, control and communications (including automatic data processing systems), as well as
for display on the containers themselves.
The methods of displaying identification and certain other data (including operational data) on
containers by means of permanent marks are included.
1.2 This document specifies:
a) a container identification system, with an associated system for verifying the accuracy of its use,
having:
— mandatory marks for the presentation of the identification system for visual interpretation,
and
— features to be used in optional Automatic Equipment Identification (AEI) and electronic data
interchange (EDI);
b) a coding system for data on container size and type, with corresponding marks for their display;
c) operational marks, both mandatory and optional;
d) physical presentation of marks on the container.
1.3 The terms “mandatory” and “optional” in this document are used to differentiate those ISO
marking provisions which shall necessarily be fulfilled by all containers from those which are not
required of all containers. The optional marks are included to further comprehension and promote
uniform application of the optional mark. If a choice has been made to display an optional mark, the
provisions laid down in this document relating to the mark shall be applied. The terms “mandatory”
and “optional” do not refer to requirements of any regulatory body.
1.4 This document applies to all freight containers covered by International Standards ISO 668, parts
1 to 5 of ISO 1496, ISO 8323 and should, wherever appropriate and practicable, be applied:
— to containers other than those covered by the International Standards mentioned in Clause 2;
— to container-related and/or detachable equipment.
NOTE 1 Containers marked according to previous editions of ISO 6346 need not be re-marked.
1.5 This document does not cover temporary operational marks of any kind, permanent marks,
data plates, etc. which may be required by intergovernmental agreements, national legislation or
nongovernmental organizations.
NOTE 2 Some of the major international conventions whose container-marking requirements are not covered
in this document are as follows:
— International Convention for Safe Containers (1972, as amended) (CSC), International Maritime Organization
(IMO);
ISO 6346:2022(E)
— Customs Convention on Containers 1956 and 1972, related to temporary admission and transport under
customs seal.
— Convention on Temporary Admission (Istanbul, 26 June 1990), related to temporary admission.
It should not be assumed that this list is exhaustive.
This document does not cover the display of technical data on tank containers (see ISO 1496-3), nor
does it, in any way, include identification marks or safety signs for items of cargo which may be carried
in freight containers.

the series of significant numerals is 1234, the serial number is 001234).
4.1.5 Check digit
Reference (4) in Figures 1 to 4
The check digit provides a means of validating the transmission accuracy of the owner code and serial
number and shall be determined as in Annex A. The check digit shall validate the owner code, equipment
category identifier and serial number of the container.
4.2 Identification marks
The use of marks in accordance with the identification system specified in 4.1, i.e. owner code,
equipment category identifier, serial number and check digit, is mandatory for freight containers and
recommended for all equipment as stated in 4.1.3. The characteristics (size, shape, layout, etc.) detailed
in 7.1 and 7.2.1 shall be displayed as nearly as practicable in accordance with Clause 7, i.e., legible to the
human eye.
5 Size and type codes and their associated marks
5.1 Purpose
The type and main external dimensions of the container shall be identified with codes marked on the
container. Only those freight containers which conform with both the ISO top-handling capability and
structural stacking requirements set forth in ISO 1496 shall be marked with size and type codes in
accordance with 5.2.2 and 5.2.3.
5.2 Size and type codes
5.2.1 General
This information is mandatory for the marking of containers covered by the International Standards
listed in Clause 2 and shall be coded as in 5.2.2 and 5.2.3.
The size and type codes, when displayed on the container, shall be used as a whole, i.e., the information
must not be broken into its component parts.
The size and type codes shall be displayed in accordance with Clause 7.
5.2.2 Size: two alphanumeric characters
Reference (5) in Figures 1 to 4
ISO 6346:2022(E)
The container size (i.e. external dimensions) shall be indicated by two characters as follows:
— First character: numeric or alphabetic character representing the length.
— Second character: numeric or alphabetic character representing the width and the height.
These two characters shall be determined in accordance with Annex D.
5.2.3 Type: two characters
Reference (6) in Figures 1 to 4
The container type and main characteristics shall be indicated by two characters as follows:
— First character: alphabetic character representing the container type.
— Second character: numeric or alphabetic character representing main characteristics related to the
container type.
These two characters shall be selected in accordance with Annex E.
NOTE For the purpose of exchanging data when indication of the main characteristics is not essential, the
“type group code designation” as shown in Annex E can be used.
6 Operational marks
6.1 General
The marks in this section are not intended to correspond to any particular code (e.g., for use in data
transmission or any other purpose). They are solely intended as markings for use on freight containers
to convey certain information or give visual warnings.
6.2 Mandatory operational marks
6.2.1 Maximum gross and tare masses
The maximum gross and tare masses shall be marked on a container as:
MAX GROSS 00 000 kg
00 000 lb
TARE 00 000 kg
00 000 lb
For safety reasons, containers tested in conformance with the approved methods specified in that part
of ISO 1496 applicable to the type of container in question, i.e., parts 1, 2, 3, 4 or 5 of ISO 1496, shall be
uniformly marked with the maximum gross mass used for those tests.
Furthermore, the “maximum gross mass” marked on the container in accordance with this document
shall be identical to that shown on the CSC Safety Approval Plate.
As indicated above, the masses shall be expressed in both kilograms (kg) and pounds (lb).
NOTE 1 kg = 2 204 lb.
6.2.2 Air/surface container symbol
All air/surface containers shall display the symbol specified in Annex B.
ISO 6346:2022(E)
6.2.3 Warning sign of overhead electrical danger

in Annex C.
6.2.4 Height mark for containers higher than 2,6 m (8 ft 6 in)
All containers higher than 2,6 m (8 ft 6 in) shall bear the following mandatory marks:
a) on both sides, a height mark similar to that described in Annex F;
b) an area of alternating black and yellow stripes on the top members of each end frame and side wall
at each corner adjacent to the corner fitting, of 300 mm (12 in) minimum length, that can be seen
from the ground or from the top. See Figure 5.
In addition, any other optional marks, such as a mirror image of the mark described in Annex F, may be
displayed at any convenient location (e.g., front wall).
6.2.5 Width mark for containers with an overall width greater than 2 438 m (8 ft).
All containers with an overall width greater than 2 438 m (8 ft) shall bear a mark similar to that
described in Annex G on the ends and the roof at both ends.
Where there is insufficient space to fit the marking on the ends or the roof, for example on tank
containers, the marking shall be as wide as is practicable on the ends and may be omitted on the roof.
