Dear Mr. Mazzullo,
The Hazardous Materials Transportation Regulations (HMR) provide exceptions from
some requirements when certain materials or types of packaging is transported by a
private or contract carrier. 49 CFR 173.29 (c) (2) excepts shipments of non-bulk
packaging containing only the residue of hazardous materials from the shipping papers
requirements when transported by contract or private carriers for reuse or reconditioning.
Hazardous material cargo inspections conducted by this Agency under the Federal Motor
Carrier Safety Administration's HM Package Inspection Program have discovered
residue containing package shipments transported by common carriers not documented
with shipping papers. The North American Standard Hazardous Materials Out-of-Service

The revised regulations on infectious substances in Docket HM-226, provide exceptions
carried by private or contract carriers in vehicles dedicated to moving those materials.
for shipments of diagnostic specimens and regulated medical waste in $173.134, when
Diagnostic specimens as are frequently transported by courier services that may or may
not have contract carrier authority. Many diagnostic specimen packages are transported
by courier services in vehicles that are carrying packages from many shippers.
The revised § 173.134, paragraph (b) (6), provides some exceptions for packages of
diagnostic specimens and regulated medical waste when transported by private or
contract carriers in motor vehicles used exclusively to transport those specimens,
for cultures and stocks of division 6.2 materials transported by private or contract carriers
biological products, and related equipment. Paragraph (c) of that section gives exceptions
in vehicles dedicated to the transportation of regulated medical waste.
3. What constitutes exclusive use of a vehicle as referenced in 173.134 (b) (6)? Could a
contract carrier use exclusively a vehicle for delivery of one shipment of diagnostic
specimens, and then return that vehicle to general use?
4. What constitutes dedicated use as referenced in paragraph (c)? Is a single truckload
shipment dedicated use for RMW transportation? What steps would have to be taken by
the carrier to remove a unit from dedicated RMW service?
Thank you for clarification on these issues.
Yours truly,
Mutal Rittel
