Use of overpacks
(a) Unless marks and labels required in Chapter 5.2, except 188.8.131.52 to 184.108.40.206, 220.127.116.11.2 to 18.104.22.168.8
and 22.214.171.124, representative of all dangerous goods in the overpack are visible, the overpack
(i) marked with the word “OVERPACK”. The lettering of the “OVERPACK” mark shall
be at least 12 mm high. The mark shall be in an official language of the country of
origin and also, if that language is not English, French or German, in English, French or
German, unless agreements, if any, concluded between the countries concerned in the
transport operation provide otherwise; and
(ii) labelled and marked with the UN number and other marks, as required for packages in
Chapter 5.2 except 126.96.36.199 to 188.8.131.52, 184.108.40.206.2 to 220.127.116.11.8 and 18.104.22.168, for each item of
dangerous goods contained in the overpack. Each applicable mark or label only needs to
be applied once.
Labelling of overpacks containing radioactive material shall be in accordance with 22.214.171.124.11.
(b) Orientation arrows illustrated in 126.96.36.199 shall be displayed on two opposite sides of overpacks
containing packages which shall be marked in accordance with 188.8.131.52.1, unless the marks
Each package of dangerous goods contained in an overpack shall comply with all applicable
provisions of ADR. The intended function of each package shall not be impaired by the overpack.
Each package bearing package orientation marks as prescribed in 184.108.40.206 and which is overpacked or
placed in a large packaging shall be oriented in accordance with such marks.
The prohibitions on mixed loading also apply to these overpacks.
Empty uncleaned packagings (including IBCs and large packagings), tanks, MEMUs, vehicles and containers for carriage in bulk
Empty uncleaned packagings (including IBCs and large packagings), tanks (including tank-vehicles,
battery-vehicles, demountable tanks, portable tanks, tank-containers, MEGCs), MEMUs, vehicles and
containers for carriage in bulk having contained dangerous goods of the different classes other than
Class 7, shall be marked and labelled as if they were full.
NOTE: For documentation, see Chapter 5.4.
Containers, tanks, IBCs, as well as other packagings and overpacks, used for the carriage of
radioactive material shall not be used for the storage or carriage of other goods unless decontaminated
below the level of 0.4 Bq/cm2 for beta and gamma emitters and low toxicity alpha emitters and 0.04
Bq/cm2 for all other alpha emitters.
When two or more dangerous goods are packed within the same outer packaging, the package shall be
labelled and marked as required for each substance or article. If the same label is required for different
goods, it only needs to be applied once.
General provisions for Class 7
Approval of shipments and notificat
In addition to the approval of package designs described in Chapter 6.4, multilateral shipment
approval is also required in certain circumstances (220.127.116.11.2 and 18.104.22.168.3). In some circumstances it is
also necessary to notify competent authorities of a shipment (22.214.171.124.4).
Multilateral approval shall be required for:
(a) the shipment of Type B(M) packages not conforming with the requirements of 126.96.36.199 or
designed to allow controlled intermittent venting;
(b) the shipment of Type B(M) packages containing radioactive material with an activity greater
than 3 000 A1 or 3 000 A2, as appropriate, or 1 000 TBq, whichever is the lower; and
(c) The shipment of packages containing fissile materials if the sum of the criticality safety
indexes of the packages in a single vehicle or container exceeds 50;
except that a competent authority may authorize carriage into or through its country without shipment
approval, by a specific provision in its design approval (see 188.8.131.52.1).
Shipment approval by special arrangement
Provisions may be approved by a competent authority under which a consignment, which does not
satisfy all of the applicable requirements of ADR may be carried under special arrangement
Notification to competent authorities is required as follows:
(a) Before the first shipment of any package requiring competent authority approval, the consignor
shall ensure that copies of each applicable competent authority certificate applying to that
package design have been submitted to the competent authority of the country of origin of the
shipment and to the competent authority of each country through or into which the
consignment is to be carried. The consignor is not required to await an acknowledgement from
the competent authority, nor is the competent authority required to make such
acknowledgement of receipt of the certificate;
(b) For each of the following types of shipments:
(i) Type C packages containing radioactive material with an activity greater than 3 000 A1
or 3 000 A2, as appropriate, or 1 000 TBq, whichever is the lower;
(ii) Type B(U) packages containing radioactive material with an activity greater than 3 000
A1 or 3 000 A2, as appropriate, or 1 000 TBq, whichever is the lower;
(iii) Type B(M) packages;
(iv) Shipment under special arrangement;
The consignor shall notify the competent authority of the country of origin of the shipment and
the competent authority of each country through or into which the consignment is to be carried.
This notification shall be in the hands of each competent authority prior to the commencement
of the shipment, and preferably at least 7 days in advance;
(c) The consignor is not required to send a separate notification if the required information has
been included in the application for approval of shipment (see 184.108.40.206);
(d) The consignment notification shall include:
(i) sufficient information to enable the identification of the package or packages including
all applicable certificate numbers and identification marks;
(ii) information on the date of shipment, the expected date of arrival and proposed routeing;
(iii) the name(s) of the radioactive material(s) or nuclide(s);
(iv) descriptions of the physical and chemical forms of the radioactive material, or whether
it is special form radioactive material or low dispersible radioactive material; and
(v) the maximum activity of the radioactive contents during carriage expressed in
becquerels (Bq) with an appropriate SI prefix symbol (see 220.127.116.11). For fissile material,
the mass of fissile material (or of each fissile nuclide for mixtures when appropriate) in
grams (g), or multiples thereof, may be used in place of activity.
