Dear Mr. Wilds:
This responds to your August 8, 2001, letter regarding the applicability of the Hazardous Materials
Regulations (HMR; 49 CFR Parts 171-180) to the transportation of dental amalgam. You state that
the dental amalgam consists of 50% mercury, 25% silver and small quantities of tin, copper and zinc.
You also state that the material is not subject to the Environmental Protection Agency's manifest
requirements and none of the materials exceed their reportable quantities.
Based on the information you have provided we agree that the dental amalgam described above is not
subject to the HMR.
I hope this information is helpful.
Sincerely,
Transportation Regulations Specialist

Dear Mr. Billings:
Re: Dental Amalgam Recycling Program
This letter is to confirm the conclusion that a program to recycle dental amalgam (described more fully
below) is not regulated pursuant to the Hazardous Materials Regulations (HMR; 49CFR Parts 171 - 180).
SolmeteX, United Parcels Service of America (UPS) and recycling facilities [including, but not limited to
Mercury Waste Solutions, Inc. (MWSI)] wish to undertake a national recycling program in which dentists
will be asked to participate by recycling dental amalgam. The amalgar will be from at least two sources:
a. unused excess amalgam prepared for restoration work (referred to as non-contact amalgam)
b. amalgam removed from a patient's teeth during repair work (referred to as contact amalgam)
