Dear Mr. Kennedy:

This is in response to your May 18, 2009 letter requesting clarification on the applicability of the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180) to cadmium tungstate. You request confirmation from this office that the test report submitted with your letter provides sufficient verification that the tested materials are not subject to the requirements of the HMR.

As provided in § 173.22, it is the shipper's responsibility to properly classify a hazardous material. Such determinations are not required to be verified by this office. However, based on the test results you provided, it is our opinion that the cadmium tungstate crystals described in the test report do not meet the definition of a Division 6.1 material for oral or dermal toxicity. Provided this material does not meet the criteria for a Division 6.1 material for inhalation hazard or the definition of another hazard class, it is not subject to the HMR.

I hope this information is helpful. Please contact us if you require additional assistance.
