49 CFR 172.406 - Placement of labels.
(1) Except as provided in paragraphs (b) and (e) of this section, each label required by this subpart must -
(i) Be printed on or affixed to a surface (other than the bottom) of 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;
(2) A cylinder; and
(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;
(3) Each DOT 106 or 110 multi-unit tank car tank. Labels must be displayed on each end;
(4) Each portable tank of less than 3,785 L (1000 gallons) capacity;
