Class 3 Combustible Liquids - 49CFR 173.120b 1

1. Any liquid that does not meet the definition of any other hazard class specified in this subchapter and has a flash point above 141 degrees Fahrenheit and below 200 degrees Fahrenheit.
2. A flammable liquid with a flash point at or above 100degrees Fahrenheit that does not meet the definition of any other hazard class may be re classed as a combustible liquid. This provision does not apply to transportation by vessel or aircraft, except where other means of transportation is impracticable. An elevated temperature material that meets the definition of a Class 3 material because it is intentionally heated and offered for transportation or transported at or above its flash point may not be re classed as a combustible liquid.
3. A combustible liquid which does not sustain combustion is not subject to the requirements of this subchapter as a combustible liquid. Either the test method specified in ASTM 4206 or the procedure in Appendix H of this part may be used to determine if a material sustains combustion when heated under test conditions and exposed to an external source of flame.
