Dear Ms. Edminster:
This is in response to your September 28, 2004 letter requesting clarification regarding the
prohibited labeling requirements under the Hazardous Materials Regulations (HMR; 49 CFR
Parts 171-180). Specifically, you ask if the logo displayed on the submitted product label
would be in violation of the prohibited labeling requirements specified in § 172.401(b).
In accordance with § 172.401(b), a package containing hazardous materials may not bear any
marking or label that by its color, design, or shape could be confused with or conflict with a
label prescribed by the HMR. It is this office's opinion that the size, design and shape of the
logo you submitted would not conflict or be confused with the labels prescribed by the HMR.
Therefore, the submitted logo is not prohibited under the provisions of § 172.401(b).
I hope this information is helpful. Please contact us if you require additional assistance.
Sincerely
Hotte
