• If a dangerous good is forbidden from transport unless it is stabilized first, the word STABILIZED must be added to the proper shipping name.

Except for self-reactive substances and organic peroxides, and unless it is already included in capital letters in the proper shipping name shown in the Dangerous Goods List, the word “STABILIZED” must be added to the proper shipping name of any substance that, without stabilization, would be forbidden from transport due to its potential to dangerously react under conditions normally encountered in transport (for example, TOXIC LIQUID, ORGANIC, N.O.S., STABILIZED).

When temperature control is used to stabilize these substances to prevent development of dangerous excess pressure or evolution of excessive heat, or when chemical stabilization is used in combination with temperature control, then:

• For liquids and solids where the self-accelerating polymerization temperature (SAPT) is less than or equal to prescribed levels, special provisions may apply;
• Unless it is already included in capital letters in the proper shipping name, the words “TEMPERATURE CONTROLLED” must be added;
• For gases: the conditions of transport must be approved by the competent authority.

Hydrates may be transported using the proper shipping name for the anhydrous substance.
