Are there any exceptions to the Hazardous Materials Regulations?
['Hazmat']
- Some exceptions to the HMR exist, such as the limited quantity exception and certain combinations of contents and packagings, but often only if the situation meets specific requirements.
Throughout the Hazardous Materials Regulations (HMR), there are exceptions to the regulations. These exceptions provide relief from requirements in the regulations.
In many situations, the relief is authorized only if specific requirements are met. Anyone can use these exceptions, as long as they meet all the requirements.
Some examples of exceptions include:
- 171.4 for marine pollutants;
- 172.504(c) for not placarding non-bulk packages of Table 2 materials in quantities of 1,001 pounds or less;
- 173.6 for Materials of Trade; and
- 173.150(f) for combustible liquids in non-bulk packaging.
Exceptions for limited quantities and consumer commodities for a wide range of hazards can be found in sections 173.150 to 173.156.
