Dear Mr. Booker:
This responds to your January 19,2009 letter requesting clarification of the use of the
materials of trade exceptions under the Hazardous Materials Regulations (HMR; 49 CFR
Parts 171 -1 80). According to your letter, your company transports regulated medical waste
(UN3291) between facilities at an industrial park in company-owned and -operated vehicles
for the purpose of consolidation of the material at one facility for subsequent pickup and
disposal by a separate company. You ask whether you may transport your regulated medical
waste as a material of trade.
The answer is yes. It is the opinion of this Office that regulated medical waste transported by
your company's employees in company vehicles in direct support of your business may be
transported as a material of trade. In accordance with 5 171.8, the definition of a material of
trade includes a hazardous material, other than a hazardous waste, that is carried on a motor
vehicle by a private motor carrier in direct support of a principal business that is other than
transportation by motor vehicle. Therefore, provided the regulated medical waste is
packaged in conformance with 9 173.6 paragraphs (a)(4) and (a)(4)(ii), and otherwise
conforms to the conditions of 173.6, the regulated medical waste may be transported by
your company as a material of trade.
I hope this information is helpful. Please contact us if you require additional assistance.
Sincerely,
hief, Standards Development

Office of Hazardous Materials Standards

Dear Mr. Betts,
Our company, DENS0 Manufacturing Tennessee Inc., manufactures auto parts and
occupies several facilities on either side of the street in a small industrial park. The
maximum distance from any given facility to another is less than 1 mile. Each facility
generates, or has the potential to generate materials classified as LPJ 3291, Regulated
Medical Wastes. The materials are generated at our first aid stations and restrooms.
Sharps are stored in closed, puncture resistant containers and all other materials are
collected and stored in rigid containers with poly liners and do not contain liquids.
Our goal is to consolidate the material at one DENS0 facility. It would then be picked up
by an approved treatment company. In this scenario, we would utilize our company
personnel and vehicles to transport the materials to the consolidation site.
Would the materials for trade exception found in 49 CFR 173.6 apply to the transport for
consolidation of the materials, provided the packaging and weight requirements of
49 CFR 173.6(a-e) are met?
Any information or guidance you could offer is appreciated.
Sincerely,
Senior Manager, Legal Services and Corporate Compliance
DENS0 Manufacturing Tennessee, Inc.
