UN 2014Hydrogen peroxide, aqueous solutions with more than 40 percent but not more than 60 percent hydrogen peroxide (stabilized as necessary) or Hydrogen peroxide, aqueous solutions with not less than 20 percent but not more than 40 percent hydrogen peroxide (stabilized as necessary)

Division 5.1

Oxidizing substances

Summary

UN 2014 is the UN number for hydrogen peroxide, aqueous solutions with more than 40 percent but not more than 60 percent hydrogen peroxide (stabilized as necessary) or Hydrogen peroxide, aqueous solutions with not less than 20 percent but not more than 40 percent hydrogen peroxide (stabilized as necessary). It is classed in Division 5.1 (oxidizing substances) of Class 5 for transport. Packing group II. Emergency responders use ERG guide 140.
