the package or containment device containing the hazardous material; and
    (ii) Be located on the same surface of the package and near the 
proper shipping name marking, if the package dimensions are adequate.
    (2) Except as provided in paragraph (e) of this section, duplicate 
labeling is not required on a package or containment device (such as to 
satisfy redundant labeling requirements).
    (b) Exceptions. A label may be printed on or placed on a securely 
affixed tag, or may be affixed by other suitable means to:
    (1) A package that contains no radioactive material and which has 
dimensions less than those of the required label;

    (3) A package which has such an irregular surface that a label 
cannot be satisfactorily affixed.
    (c) Placement of multiple labels. When primary and subsidiary hazard 
labels are required, they must be displayed next to each other. 
Placement conforms to this requirement if labels are within 150 mm (6 
inches) of one another.
    (d) Contrast with background. Each label must be printed on or 
affixed to a background of contrasting color, or must have a dotted or 
solid line outer border.
    (e) Duplicate labeling. Generally, only one of each different 
required label must be displayed on a package. However, duplicate labels 
must be displayed on at least two sides or two ends (other than the 
bottom) of--
    (1) Each package or overpack having a volume of 1.8 m \3\ (64 cubic 
feet) or more;
    (2) Each non-bulk package containing a radioactive material;

and
    (5) Each freight container or aircraft unit load device having a 
volume of 1.8 m \3\ (64 cubic feet) or more, but less than 18 m \3\ (640 
cubic feet). One of each required label must be displayed on or near the 
closure.

obscured by markings or attachments.
