Dear Mr. Tallman:
This is in response to your letter of February 10, 1998, requesting clarification of the Precedence of Hazard requirements in § 173.2a of the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180). Your question is presented in the following scenario:
A package contains a mixture of radioactive materials and flammable liquids. The mixture can be named either "Radioactive material, LSA II" or "Radioactive material, limited quantity" and thus be reclassed as a flammable liquid due to the hierarchy of the precedence table. Does the shipper have the choice to ship it as either of these classifications or is he bound by the HMR to use a specific classification?
In a situation where a shipper has a mixture of radioactive materials and flammable liquids that meet the definition of a limited quantity, the shipper has the choice to either classify the material as a limited quantity or to maintain the material's original classification. If the shipper chooses the proper shipping name "Radioactive material, limited quantity" as in the example above, and that material meets the definition of more than one hazard class or division, it shall be classed in accordance with § 173.423.
I hope this answers your inquiry. If you need additional assistance, do not hesitate to contact us.
Sincerely,
Delmer F. Billings
