Reference No. 14-0228

Dear Mr. Romach:

This is in response to your November 19, 2014 letter requesting clarification of the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180) applicable to the proper shipping name marking size for IBCs that are labeled instead of placarded.  Specifically, in the case of an IBC labeled in accordance with § 172.514(c), you ask if a proper shipping name with a height of 6 mm and a UN identification number with a height of 12 mm displayed adjacent to the hazard label is authorized.  

The answer is yes.  Section 172.336(d) provides a special provision for the display of identification numbers that permits a bulk packaging that is labeled instead of placarded in accordance with 172.514(c) to display identification number markings consistent with the requirements of § 172.301(a)(1).  Section 172.301(a)(1) prescribes a 12 mm minimum height requirement for the identification number for an IBC; however, a minimum height for the proper shipping name is not prescribed.  In addition, a transitional exception provided in § 172.301(a)(1)(i) prescribes that for domestic transportation, until January 1, 2017, identification number markings are not subject to the 12 mm minimum height requirement.

I trust this information is helpful.  If you have further questions, please do not hesitate to contact this office.

Sincerely,

Shane C. Kelley
