What does ORM-D stand for in hazardous materials shipping?

ORM-D stands for "Other Regulated Materials - Domestic." This designation is used to classify certain hazardous materials that, while still regulated, can be transported with less stringent requirements than other hazardous materials due to their limited quantity and lower risks. This classification ensures that these materials can be shipped safely while streamlining the regulatory process for businesses and consumers.

The other choices do not accurately reflect the established definition of ORM-D. For instance, "Other restricted materials" and "Odor regulated materials" do not capture the essence of the ORM-D classification in relation to hazardous materials shipping. Similarly, "Other relevant materials" does not provide a clear association with the specific regulations applied to hazardous materials as required by shipping guidelines. Therefore, understanding that ORM-D pertains to "Other Regulated Materials - Domestic" is crucial for proper compliance in the shipping of these materials.
