Reference No. 18-0018

Dear Mr. Ames:

This letter is in response to your February 7, 2018, letter requesting clarification of the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180) applicable to the classification of Meals, Ready to Eat (MREs) packaged with the heating source for operational rations.  In your letter and subsequent phone call, you describe and provide safety data sheets (SDS) for an ethyl alcohol fuel source, classified as a Division 4.1 flammable solid in Packing Group (PG) III.  You explain the fuel blocks are individually packaged in two individually sealed capsules containing 1 ounce or less of fuel, which are further contained in a sealed pouch with other non hazardous materials.  You include a picture of this configuration in an image showing a pouch titled “Cold Weather Meal.”  Specifically, you ask whether these MREs are subject to the HMR as a hazardous material.

PHMSA regulates the transportation in commerce of hazardous materials in an “amount and form [that] may pose an unreasonable risk to health and safety or property” in accordance with 49 U.S.C 5103, as delegated to PHMSA in 49 CFR §§ 1.96(b) and 1.97(b).  As described in your letter, the fuel blocks meet the definition of a PG III flammable solid hazard and, therefore, meet the definition of a hazardous material subject to the HMR.  However, based on the information provided in your letter, your product may meet the excepted quantities provisions of § 173.4 and/or the exceptions for Class 4 materials in § 173.151, but not the de minimis exception in § 173.4b.

I hope this information is helpful.  Please contact us if we can be of further assistance.

Sincerely,

T. Glenn Foster
