Dear Mr. Carey:
This responds to your letter requesting clarification of the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180) applicable to the classification of a sample material with an unknown hazard. In your letter, you state that your organization is attempting to transport a sample of an unknown material suspected of containing a toxic material. You ask how the HMR apply to such a material being transported to an army laboratory for testing and analysis.
Section l72.10l(c)(11), states that except for certain materials, a shipper may assign a tentative shipping name, hazard class, and identification number to a material based on the shipper's knowledge of the material, the hazard precedence prescribed in § l73.2a, and defining hazard class criteria in Subchapter C. In this context, "tentative" means a temporary selection of a proper shipping name and hazard class used for a material until a more definite proper shipping name and hazard class can be assigned based on test data and analysis.
Exact physical and chemical properties of many materials may be unknown because concentrations of the components vary from shipment to shipment. Therefore, the use of a tentative classification and proper shipping name is authorized. However, should a shipper obtain more specific data on the properties of the material, the hazard class and proper shipping name must be modified, as applicable.
I hope this satisfies your inquiry. Please contact us if we can be of further assistance.
Sincerely,
T. Glenn Foster
