Dear Mr. Pitts:
This responds to your letter to Mr. Danny Shelton, Federal Motor Carrier Safety Administration,
concerning requirements in the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180)
applicable to the marking of MC 331 cargo tanks marked or certified after October 1, 2004.
Specifically, you ask if the requirements concerning metal name plates and specification plates
apply to the cargo tank or to the cargo tank motor vehicle (CTMV). I apologize for the delay in
responding and any inconvenience it may have caused.
In accordance with § 178.337-17, an MC331 cargo tank certified after October 1, 2004, must
have a metal name plate (also referred to as an ASME plate) permanently attached to the cargo
tank. In addition, an MC331 cargo tank motor vehicle certified after October 1, 2004, must have
a specification plate that includes the information specified in § 178.337-17(c). You are correct
that, as currently written, § 178.337-17 is not clear as to these requirements. We will clarify the
name plate and specification plate requirements in a future rulemaking.
You also asked if the HMR require the cargo tank assembler's CT number to be included on the
specification plate. Currently, the CT number is not required to be shown on the specification
plate.
I hope this satisfies your inquiry. If you have further questions, please do not hesitate to contact
this office.
Sincerely,
Chief, Standard Development
Office of Hazardous Materials Standards
