Ref. No. 10-0112

Dear Mr. Wagner,

This responds to your letter dated May 7, 2010 requesting clarification of the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180) as they apply to an aqueous solution of alcohol that your company ships. The material that you ship contains 20% isopropyl alcohol, more than 75% water, and less than 5% of various non-hazardous surfactants. Specifically, you ask if the product described meets the exception for aqueous solutions of alcohol under the HMR.

The answer is yes. Aqueous solutions of alcohol, that contain no other hazardous materials, are excepted from the requirements of the HMR when they contain 24% or less alcohol by volume and no less than 50% water.

I hope this information is helpful. If you have further questions, please contact this Office.

Sincerely,

Charles E. Betts

Chief, Standards Development
