Dear Mr. Lesser:

This responds to your January 23, 2013 e-mail requesting clarification of the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180) applicable to use of the DANGEROUS placard.  Your questions are paraphrased and answered as follows:

Q1.   Recently, there have been a number of rulemaking actions resulting in further alignment (harmonization) of the HMR with the various international standards.  Does the Pipeline and Hazardous Materials Safety Administration (PHMSA) intend to phase-out the DANGEROUS placard as a result of it not being recognized in international transportation?

A1.   The answer is no.

Q2.   If vessel transportation of a cargo transport unit (CTU) containing hazardous materials is routed through a foreign port but originates and terminates within the United States, is the DANGEROUS placard authorized display in accordance with the HMR?

A2.   The answer is no.  The DANGEROUS placard is not recognized by the International Dangerous Goods Code (IMDG Code).  However, the display of both the DANGEROUS placard and placard(s) corresponding to the actual hazardous material contained in the CTU is authorized.

Q3.   Is display of the DANGEROUS placard authorized in domestic transportation by vessel?

A3.   The answer is yes.

I hope this information is helpful.  Please contact this office should you have additional questions.
