Dear Mr. Pelsor:

This is in response to your e-mail asking whether the abbreviation "TT" is acceptable under the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180) for representing a cargo tank when indicating the packaging type on shipping papers.  You point out that the U.S. Environmental Protection Agency (EPA) authorizes the abbreviation for hazardous waste manifests.  In a follow-up telephone conversation with a member of my staff you asked whether "TT" would be an acceptable abbreviation on shipping papers for hazardous materials that do not require a hazardous waste manifest.

The answer is yes.  The abbreviation "TT" is a commonly accepted and recognizable abbreviation for cargo tanks

(tank trucks) and, thus, may be used to indicate a shipment"s packaging type on shipping papers in accordance with § 172.202(a)(6) of the HMR.

I hope this information is helpful.  Please contact this office should you have additional questions.
