Dear Mr. Blase:

This is in response to your letter dated July 20, 1999, requesting clarification of the Hazardous Materials Regulations (HMR; 49 CFR 171-180) as they relate to the transportation of Class 9 hazardous materials.  Specifically, you ask whether a CLASS 9 placard is required to be displayed for domestic transportation.

As provided by § 172.504 (f)(9), the answer is no; a CLASS 9 placard is not required for domestic transportation.  This exclusion from the CLASS 9 placarding requirement applies to both non-bulk and bulk packages.  Each non-bulk package. must be. marked with the proper shipping name and identification (ED) number as provided for by § 172.301 and must display a CLASS 9 Label as provided by § 172.400. In addition, if a, non-bulk package contains a hazardous substance, the letters "RQ" must be marked on the package in association with the proper shipping name as provided for by § 172.324. Each bulk package must be marked on each side and each end with the appropriate ID number displayed on a placard, orange panel, or when appropriate a white square-on-point configuration.  However, if a carrier chooses to display CLASS 9 placards on a bulk package, the ID number may be displayed on the placard or orange panel as provided by § 172.332(c).

I hope this information is helpful.  Should you have further questions, please contact us.
