Packagings shall be manufactured and tested under a quality assurance programme which satisfies the
competent authority in order to ensure that each packaging meets the requirements of this Chapter.
NOTE: ISO 16106:2006 "Packaging – Transport packages for dangerous goods – Dangerous
goods packagings, intermediate bulk containers (IBCs) and large packagings – Guidelines for the
application of ISO 9001" provides acceptable guidance on procedures which may be followed.
Manufacturers and subsequent distributors of packagings shall provide information regarding
procedures to be followed and a description of the types and dimensions of closures (including
required gaskets) and any other components needed to ensure that packages as presented for carriage
are capable of passing the applicable performance tests of this Chapter.
Code for designating types of packagings
The codes for designating types of packagings are set out in 188.8.131.52.
The letters "U" or "W" may follow the packaging code. The letter "U" signifies a special packaging
conforming to the requirements of 184.108.40.206.6. The letter "W" signifies that the packaging, although, of
the same type indicated by the code is manufactured to a specification different from that in 6.1.4 and
is considered equivalent under the requirements of 220.127.116.11.
NOTE 1: The marks indicate that the packaging which bears them corresponds to a successfully
tested design type and that it complies with the requirements of this Chapter which are related to the
manufacture, but not to the use, of the packaging.
NOTE 2: The marks are intended to be of assistance to packaging manufacturers, reconditioners,
packaging users, carriers and regulatory authorities.
NOTE 3: The marks do not always provide full details of the test levels, etc., and these may need to
be taken further into account, e.g. by reference to a test certificate, to test reports or to a register of
successfully tested packagings.
Each packaging intended for use according to ADR shall bear marks which are durable, legible and
placed in a location and of such a size relative to the packaging as to be readily visible. For packages
with a gross mass of more than 30 kg, the marks or a duplicate thereof shall appear on the top or on a
side of the packaging. Letters, numerals and symbols shall be at least 12 mm high, except for
packagings of 30 litres or 30 kg capacity or less, when they shall be at least 6 mm in height and for
packagings of 5 litres or 5 kg or less when they shall be of an appropriate size.
A packaging that meets the requirements of this section and of 6.3.5 shall be marked with:
(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;
(b) The code designating the type of packaging according to the requirements of 6.1.2;
(c) The text "CLASS 6.2";
(d) The last two digits of the year of manufacture of the packaging;
(e) The state authorizing the allocation of the mark, indicated by the distinguishing sign used on
vehicles in international road traffic1;
(f) The name of the manufacturer or other identification of the packaging specified by the
(g) For packagings meeting the requirements of 18.104.22.168.6, the letter "U", inserted immediately
following the mark required in (b) above.
Marks shall be applied in the sequence shown in 22.214.171.124 (a) to (g); each mark required in these subparagraphs
shall be clearly separated, e.g. by a slash or space, so as to be easily identifiable. For
examples, see 126.96.36.199.
Any additional marks authorized by a competent authority shall still enable the marks required in
188.8.131.52 to be correctly identified.

Test requirements for packagings
Performance and frequency of tests
The design type of each packaging shall be tested as provided in this section in accordance with
procedures established by the competent authority allowing the allocation of the mark and shall be
approved by this competent authority.
Each packaging design type shall successfully pass the tests prescribed in this Chapter before being
used. A packaging design type is defined by the design, size, material and thickness, manner of
construction and packing, but may include various surface treatments. It also includes packagings
which differ from the design type only in their lesser design height.
Tests shall be repeated on production samples at intervals established by the competent authority.
