Mr. Roland M. Kelley                 Reference  No. 02-0265
Sandia National Laboratories
P.O. Box 5800 MS 1120
Albuquerque, NM 87185

Dear Mr. Kelley:

This is in response to your facsimile dated October 1, 2002, and subsequent telephone conversation with Sandra Webb, of my staff, requesting clarification of the Hazardous Materials Regulations (HMR; 49 CR Parts 171-180).  Specifically, you asked whether the "UN" symbol you submitted for our review is acceptable as a marking on a UN standard packaging.  We apologize for any misinformation you received from this office.

The markings as shown on the examples, enclosed with your letter, do not conform with the requirements in § 179.503. As provided in § 178.503, a packaging which meets the UN standard and has been tested in accordance with Subpart L of Part 178, of the HMR, must, be marked with the UN symbol as illustrated in 49 CFR § 178.503(e)(1).  The example symbol you submitted is not displayed in a solid circle as illustrated in § 178.503(e)(1), thus not acceptable.

I hope this information is helpful.
