Dear Mr. Kilian:
This is in response to your letter dated September 16, 1998,
regarding the applicability of the Hazardous Materials
Regulations (HMR; 49 CFR Parts 171-180) to ferrosilicon with 75
percent silicon.
The HMR govern the transportation of hazardous materials in
commerce.
Under 49 CFR 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.
Based on the test results you provided, it is our opinion that
the ferrosilicon imported by your company does not meet the
criteria of a Division 4.3 and provided it does not meet any
other hazard class, it is not subject to the HMR.
I hope this satisfies your reguest.
Sincerely,
•
