Dear Mr. Poulos:
This responds to your March 28, 2007 letter requesting clarification on the materials of
trade (MOTS) exception in §173.6 under the Hazardous Materials Regulations (HMR; 49
CFR Parts 171-180). Specifically, you ask if government contractors in support of
(ethanol) on public roads may use the exception if they meet the provisions in §173.6.
government research activities transporting less than 200 kg of a Class 3 material
The answer is yes. One criterion for using the MOTS exception, as defined in §171.8, is
that the hazardous material must be transported by a private carrier in direct support of its
principal business, which may not be transportation by motor vehicle. A government
contractor that supports government research activities may transport hazardous material
under the MOTS exception provided the contractor's principal business is not
transportation. If you transport a Class 3 material (ethanol) under the MOTS exception, it
must be contained in a packaging having a gross mass or capacity not over 30 kg (66
pounds) or 30 L (8 gallons) for a Packing Group II or III material. Packagings must be
leak tight and be securely closed, secured against movement, and protected against
damage. Except for diluted mixtures meeting the requirements of §173.6(a)(1)(iii), the
aggregate gross weight of all materials of trade on a motor vehicle may not exceed 200
kg (440 pounds).
I hope this answers your inquiry.
Sincerely,
Chief, Standards Development
