Dear Mr. Swenke:

This responds to your September 7, 2010 letter requesting clarification of the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180). You indicate that your product is a 2oz., non-aerosolized (pump spray) ironing starch that does not meet the definition of a hazardous material under the HMR. You ask for a letter of interpretation enabling travelers and flight attendants to carry your product aboard aircraft.

Section173.22 requires a shipper to properly class and describe a hazardous material for transportation in commerce. This Office does not perform that function. However, based on the information provided in your letter and subsequent email correspondence with a member of my staff, it is the opinion of this Office that the ironing starch you describe does not meet the definition of a hazardous material and is not subject to regulation under the HMR.

It should be noted that the Transportation Security Administration (TSA), the agency responsible for security in all modes of transportation, including civil aviation, has the authority to restrict passengers from carrying materials perceived as security threats. Therefore, TSA officials may confiscate materials that they believe to be security risks even if the materials are not classified as hazardous under the HMR.

I trust this satisfies your inquiry. Please contact us if we can be of further assistance.
