Dear Mr. Malatesta:
This responds to your letter regarding the Materials of Trade (MOTS) and the Class 9 placarding
exceptions for Class 9 materials shipped under the Hazardous Materials Regulations (HMR; 49 CFR
inconvenience.
Parts 171-180). We apologize for the delay in responding and hope it has not caused any
You stated that your company is a private carrier of Class 9 materials for domestic end-use
transportation only, which may include bulk packagings. The material is described as "Other regulated
substances, liquid, n.o.s., 9, NA 3082, III," and may be shipped in a reportable quantity (RQ). You
asked, using either the MOTS or placarding exceptions for Class 9 materials, can a Class 9 material be
transported without displaying the CLASS 9 placards?
The answer is yes. By definition, MOTS include a hazardous material that is transported by a private
carrier in direct support of its principal business which may not be transportation by motor vehicle: A
Class 9 material of not more than 1500 L (400 gallons) for a diluted mixture, not to exceed 2%
concentration, may be shipped under the MOTS exception. A bulk packaging containing a diluted
mixture of a Class 9 material must be marked on two opposing sides with the identification number of
the material. The identification number may be displayed on placards, orange panels, or on a white
square-on-point configuration. A hazardous material (e.g., Class 9) shipped under the MOTS
exception is not subject to any other requirements, including placarding, when transported by motor
vehicle if all the conditions of § 173.6 are met.

square-on-point display configuration. For a Class 9 material shipped in a quantity which equals or
exceeds a RQ of a hazardous substance, the shipping paper and a non-bulk packaging must contain the
letters "RQ". (See §§ 172.203(c),§ 172.324,172.332 and 172.504(f)(9)).
