without the need for accumulation control under the following conditions:
(a) The conditions of 6.4.11.1 (a);
(b) The conditions consistent with the assessment provisions stated in 6.4.11.12 (b) and
6.4.11.13 (b) for packages.
Classification of packages or unpacked material
The quantity of radioactive material in a package shall not exceed the relevant limits for the package
type as specified below.
Classification as excepted package
A package may be classified as an excepted package if it meets one of the following conditions:
(a) It is an empty package having contained radioactive material;
(b) It contains instruments or articles not exceeding the activity limits specified in columns (2) and
(3) of Table 2.2.7.2.4.1.2;
(c) It contains articles manufactured of natural uranium, depleted uranium or natural thorium;
(d) It contains radioactive material not exceeding the activity limits specified in column (4) of
Table 2.2.7.2.4.1.2; or
(e) It contains less than 0.1 kg of uranium hexafluoride not exceeding the activity limits specified
in column (4) of Table 2.2.7.2.4.1.2.
A package containing radioactive material may be classified as an excepted package provided that the
radiation level at any point on its external surface does not exceed 5 μSv/h.

a For mixtures of radionuclides, see 2.2.7.2.2.4 to 2.2.7.2.2.6.
Radioactive material which is enclosed in or is included as a component part of an instrument or other
manufactured article may be classified under UN No. 2911 RADIOACTIVE MATERIAL,
EXCEPTED PACKAGE - INSTRUMENTS or ARTICLES provided that:
(a) The radiation level at 10 cm from any point on the external surface of any unpackaged
instrument or article is not greater than 0.1 mSv/h;
(b) Each instrument or manufactured article bears the mark "RADIOACTIVE" on its external
surface except for the following:
(i) radioluminescent time-pieces or devices;
(ii) consumer products that have either received regulatory approval in accordance with
1.7.1.4 (e) or do not individually exceed the activity limit for an exempt consignment in
Table 2.2.7.2.2.1 (column 5), provided such products are transported in a package that
bears the mark "RADIOACTIVE" on its internal surface in such a manner that a
warning of the presence of radioactive material is visible on opening the package; and
(iii) other instruments or articles too small to bear the mark "RADIOACTIVE", provided
that they are transported in a package that bears the mark "RADIOACTIVE" on its
internal surface in such a manner that a warning of the presence of radioactive material
is visible on opening the package;
(c) The active material is completely enclosed by non-active components (a device performing the
sole function of containing radioactive material shall not be considered to be an instrument or
manufactured article); and
(d) The limits specified in columns 2 and 3 of Table 2.2.7.2.4.1.2 are met for each individual item
and each package, respectively.
Radioactive material in forms other than as specified in 2.2.7.2.4.1.3 and with an activity not
exceeding the limits specified in column 4 of Table 2.2.7.2.4.1.2, may be classified under UN No.
2910 RADIOACTIVE MATERIAL, EXCEPTED PACKAGE - LIMITED QUANTITY OF
MATERIAL provided that:
(a) The package retains its radioactive contents under routine conditions of carriage; and
(b) The package bears the mark "RADIOACTIVE" on either:
(i) An internal surface in such a manner that a warning of the presence of radioactive
material is visible on opening the package; or
(ii) The outside of the package, where it is impractical to mark an internal surface.
Uranium hexafluoride not exceeding the limits specified in Column 4 of Table 2.2.7.2.4.1.2 may be

following conditions are met:
Type A packages shall not contain activities greater than either of the following:
(a) For special form radioactive material - A1;
(b) For all other radioactive material - A2.
