Dear Mr. Pollman:
This is in response to your letter and subsequent telephone conversation with Michael Johnsen of my
staff concerning the materials of trade (MOTs) exception in § 173.6 of the Hazardous Materials
Regulations (HMR; 49 CFR Parts 171-180). Specifically you ask whether Division 2.1 and 2.2
materials transported by your customers as private carriers either from your distribution center to their
facility or between your customers various locations may be transported under the materials of trade
exception.
Since your customers (e.g., welders or florists) transport hazardous materials in support of their
business and their primary business is not transportation by motor vehicle, the hazardous materials can
be transported under the MOTs exception provided all the provisions in § 173.6 are met. If your
customers hire a contractor or other transportation company to transport these hazardous materials, the
MOTs exceptions do not apply.
You also had a question concerning the registration and shipping paper requirements for shipments on
your company's vehicles of Division 2.1 and 2.2 materials with an aggregate gross weight of less than
1000 pounds. Companies which ship specific materials and amounts outlined in § 107.601 must
register. If your company is required to register, then § 107.620(b) requires that a copy of the
registration, or another document with the registration number (identified as the "U.S. DOT Hazmat
registration No.") be carried onboard each truck. Shipping papers must accompany all hazardous
materials shipments unless explicitly excepted from shipping paper requirements in the regulations.
I hope this satisfies your request.
Sincerely,
Delmer F. Billings

Mr. Edward T. Mazzullo,
I have some questions concerning the materials of trade exceptions (49 CFR 173.6) as they pertain to my
business. I represent a compressed gas manufacturer.
1. We have customers who ship less than 440 lb. of class 2.1 and 2.2 materials between their locations.
These customers use helium and welding gases. The materials are carried on these customers' vehicles

2.1 and 2.2 materials to take to their location. These customers also use helium and welding gases.
Their principal business is other than transportation by motor carrier. Do these customers qualify for the
materials of trade exceptions?
I also have a question concerning shipping compressed gases with the company's vehicles. We currently

For all three of these questions, the cylinders meet all DOT requirements for cylinder qualification and
proper hazard labeling. The cylinders are always properly loaded and braced for transportation.
If you have any questions or need more information to answer these questions, please contact me.
