Reference No. 14-0244

Dear Mr. Navar:

This is in response to your December 11, 2014 letter requesting clarification of the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180) applicable to the shipment of fluorosilicic acid. Specifically, you ask if this material, when in an aqueous solution with a concentration range of 23 to 25 percent fluorosilicic acid, must be described on the shipping paper using the proper shipping name followed by the word "solution" in accordance with § 172.101(c)(10).

The answer is yes. As specified in § 172.101(c)(10), the proper shipping name of a hazardous material such as fluorosilicic acid, which is comprised of a single predominant hazardous material identified in the § 172.101 Hazardous Materials Table by technical name, and one or more hazardous and/or non-hazardous material, must be described using the proper shipping name of the hazardous material and the qualifying word "mixture" or "solution," as appropriate.

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