a The code shall be completed by replacing the letter Z by a capital letter in accordance with
6.5.1.4.1 (b) to indicate the nature of the material used for the outer casing.

The letter "W" may follow the IBC code. The letter "W" signifies that the IBC, although of the same
type indicated by the code, is manufactured to a specification different from those in 6.5.5 and is
considered equivalent in accordance with the requirements in 6.5.1.1.2.

Marking

Primary marking

 
Each IBC manufactured and intended for use according to ADR shall bear    marks which are durable,
legible and placed in a location so as to be readily visible. Letters, numerals and symbols shall 
be at least 12 mm high and shall show:
 
 
(a)        The United Nations packaging symbol                                               ;
 
 
This symbol shall not be used for any purpose other than certifying that a packaging, a flexible 
bulk container, a portable tank or a MEGC complies with the relevant  requirements  in  Chapter 
6.1, 6.2, 6.3, 6.5, 6.6, 6.7 or 6.11. For metal IBCs on which the marks are stamped or embossed, 
the capital letters "UN" may be applied instead of the symbol;
 
(b)      The code designating the type of IBC according to 6.5.1.4;
 
(c)      A capital letter designating the packing group(s) for which the design type has been 
approved:
 
(i)       X for packing groups I, II and III (IBCs for solids only);
 
(ii)      Y for packing groups II and III;
 
(iii)     Z for packing group III only;
 
(d)      The month and year (last two digits) of manufacture;
(e) The State authorizing the allocation of the mark; indicated by the distinguishing sign used on 
vehicles in international road traffic1;
(f) The name or symbol of the manufacturer and other identification of the IBC as specified by the 
competent authority;
 
(g)      The stacking test load in kg. For IBCs not designed for stacking, the figure "0" shall be 
shown;
 
(h)      The maximum permissible gross mass in kg.
 
The primary marks required above shall be applied in the sequence of the subparagraphs above. The 
marks required by 6.5.2.2 and any further mark authorized by a competent authority shall still 
enable the primary marks to be correctly identified.
 
Each mark applied in accordance with (a) to (h) and with 6.5.2.2 shall be clearly separated, e.g. 
by a ace, so as to be easily identifiable.
 

 

Examples of marking for various types of IBC in accordance with 6.5.2.1.1 (a) to (h) above:

 

1 Distinguishing sign of the State of registration used on motor vehicles and trailers in international road traffic,
e.g. in accordance with the Geneva Convention on Road Traffic of 1949 or the Vienna Convention on Road Traffic of
1968.

Additional marking

Each IBC shall bear the marks required in 6.5.2.1 and, in addition, the following information which

may appear on a corrosion-resistant plate permanently attached in a place readily accessible for inspection:

 a The unit used shall be indicated.

 b See 6.5.2.2.2. This additional mark shall apply to all IBCs manufactured, repaired or remanufactured as from 1 January 2011 (see also 1.6.1.15).

The maximum permitted stacking load applicable when the IBC is in use shall be displayed on a
symbol as shown in Figure 6.5.2.2.2.1 or Figure 6.5.2.2.2.2. The symbol shall be durable and clearly
visible.
 
 
 
 
The minimum dimensions shall be 100 mm x 100 mm. The letters and numbers indicating the mass
shall be at least 12 mm high. The area within the printer’s marks indicated by the dimensional arrows
shall be square. Where dimensions are not specified, all features shall be in approximate proportion to
those shown. The mass marked above the symbol shall not exceed the load imposed during the design
type test (see 6.5.6.6.4) divided by 1.8.

 

In addition to the marks required in 6.5.2.1, flexible IBCs may bear a pictogram indicating
recommended lifting methods.

Inner receptacles that are of composite IBC design type shall be identified by the application of the
marks indicated in 6.5.2.1.1 (b), (c), (d) where this date is that of the manufacture of the plastics inner
receptacle, (e) and (f). The UN packaging symbol shall not be applied. The marks shall be applied in
the sequence shown in 6.5.2.1.1. It shall be durable, legible and placed in a location so as to be readily
visible when the inner receptacle is placed in the outer casing.
The date of the manufacture of the plastics inner receptacle may alternatively be marked on the inner
receptacle adjacent to the remainder of the marks. In such a case, the two digits of the year in the mark
and in the inner circle of the clock shall be identical. An example of an appropriate marking method
is:
 
NOTE 1: Other methods that provide the minimum required information in a durable, visible and
legible form are also acceptable.
NOTE 2: The date of manufacture of the inner receptacle may be different from the marked date of
manufacture (see 6.5.2.1), repair (see 6.5.4.5.3) or remanufacture (see 6.5.2.4) of the composite IBC.

 

Where a composite IBCs is designed in such a manner that the outer casing is intended to be
dismantled for carriage when empty (such as for return of the IBC for reuse to the original consignor),
each of the parts intended to be detached when so dismantled shall be marked with the month and year
of manufacture and the name or symbol of the manufacturer and other identification of the IBC as
specified by the competent authority (see 6.5.2.1.1 (f)).
