Dear Mr. Walker:

This is in response to your letter requesting confirmation that the test results of a sample of magnesium bearing ferrosilicon demonstrate that it is not subject to the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180).  You state that your product was tested in accordance with the test method described in 49 CFR part 173, Appendix E (revised edition as of October 1, 1996), and found it does not meet the definition of a Division 4.3 (Dangerous When Wet) material.

As provided in § 173.22, it is the shipper's responsibility to properly classify a hazardous material.  However, if the ferrosilicon handled by your company is the same material that was tested in accordance with requirements that now appear in the U.N. Manual of Tests and Criteria, and determined not to meet the Division 4.3 criteria, it is not subject to the HMR.

I hope this satisfies your request.
