§ 172.407 Label specifications.
(a) Durability. Each label, whether printed on or affixed to a package, must be durable and weather resistant. A label on a package must be able to withstand, without deterioration or a substantial change in color, a 30-day exposure to conditions incident to transportation that reasonably could be expected to be encountered by the labeled package.
(b) Design.
(1) Except for size and color, the printing, inner border, and symbol on each label must be as shown in §§ 172.411 through 172.448 of this subpart, as appropriate.
(2) The dotted line border shown on each label is not part of the label specification, except when used as an alternative for the solid line outer border to meet the requirements of § 172.406(d) of this subpart.
(c) Size.
(1) Each diamond (square-on-point) label prescribed in this subpart must be at least 100 mm (3.9 inches) on each side with each side having a solid line inner border 5.0 to 6.3 mm (0.2 to 0.25 inches) from the edge.
(2) The CARGO AIRCRAFT ONLY label must be a rectangle measuring at least 110 mm (4.3 inches) in height by 120 mm (4.7 inches) in width. The words “CARGO AIRCRAFT ONLY” must be shown in letters measuring at least 6.3 mm (0.25 inches) in height.
(3) Except as otherwise provided in this subpart, the hazard class number, or division number, as appropriate, must be at least 6.3 mm (0.25 inches) and not greater than 12.7 mm (0.5 inches).
(4) When text indicating a hazard is displayed on a label, the label name must be shown in letters measuring at least 7.6 mm (0.3 inches) in height. For SPONTANEOUSLY COMBUSTIBLE or DANGEROUS WHEN WET labels, the words “Spontaneously” and “When Wet” must be shown in letters measuring at least 5.1 mm (0.2 inches) in height.
(5) The symbol on each label must be proportionate in size to that shown in the appropriate section of this subpart.
(d) Color.
(1) The background color on each label must be as prescribed in §§ 172.411 through 172.448 of this subpart, as appropriate.
(2) The symbol, text, numbers, and border must be shown in black on a label except that—
(i) White may be used on a label with a one color background of green, red or blue.
(ii) White must be used for the text and class number for the CORROSIVE label.
(iii) White may be used for the symbol for the ORGANIC PEROXIDE label.
(3) Black and any color on a label must be able to withstand, without substantial change, a 72-hour fadeometer test (for a description of equipment designed for this purpose, see ASTM G 23-69 (1975) or ASTM G 26-70).
(i) A color on a label, upon visual examination, must fall within the color tolerances—
(A) Displayed on color charts conforming to the technical specifications for charts set forth in table 1 or 2 in appendix A to this part; or
(B) For labels printed on packaging surfaces, specified in table 3 in appendix A to this part.
(ii) Color charts conforming to appendix A to this part are on display in Office of Hazardous Materials Safety, Office of Hazardous Materials Standards, Room 8422, Nassif Building, 400 Seventh Street, SW., Washington DC 20590-0001.
(5) The following color standards in the PANTONE ® formula guide coated/uncoated (see § 171.7(b) of this subchapter) may be used to achieve the required colors on markings and hazard warning labels and placards:
(i) For Red—Use PANTONE ® 186 U
(ii) For Orange—Use PANTONE ® 151 U
(iii) For Yellow—Use PANTONE ® 109 U
(iv) For Green—Use PANTONE ® 335 U

(vi) For Purple—Use PANTONE ® 259 U
(6) Where specific colors from the PANTONE MATCHING SYSTEM ® are applied as opaque coatings, such as paint, enamel, or plastic, or where labels are printed directly on the surface of a packaging, a spectrophotometer or other instrumentation must be used to ensure a proper match with the color standards in the PANTONE ® formula guide coated/uncoated for colors prescribed in paragraph (d)(5) of this section. PANTONE ® is the property of Pantone, Inc.
(7) The specified label color must extend to the edge of the label in the area designated on each label, except for the CORROSIVE, RADIOACTIVE YELLOW-II, and RADIOACTIVE YELLOW-III labels on which the color must extend only to the inner border.
(e) Form identification. A label may contain form identification information, including the name of its maker, provided that information is printed outside the solid line inner border in no larger than 10-point type.
(f) Exceptions. Except for materials poisonous by inhalation (See § 171.8 of this subchapter), a label conforming to specifications in the UN Recommendations may be used in place of a corresponding label that conforms to the requirements of this subpart.
