Reichenberg\nAmerican Metals & Chemical Corporation\nP.O. Box 1048\nDania, FL 33004\nReference No. 07-0208\nDear Mr. Reichenberg:\nThis is in response to your October 15,2007 letter to Mr. Charles Hochrnan, Director,\nOffice of Hazardous Materials Technology, Pipeline and Hazardous Materials Safety\nAdministration, U.S. Department of Transportation (DOT), and your November 1,2007,\nand November 1 1,2007, telephone conversations with Ms. Eileen Edmonson of my staff.\nYou asked if a 20-foot long, atmospheric pressure, 5,000-6,000 gallon capacity,\nInternational Standards Organization (ISO) tank in a box or beam type frame is a portable\ntank or cargo tank under the Hazardous Materials Regulations (HNIR; 49 CFR Parts 171 -\n180). Mr. Hochman forwarded your letter to the Office of Hazardous Materials Standards\nfor response.\nAn IS0 tank in a fiarnework is a portable tank under the HMR. The portable tank must\nmeet the T-Codes listed in § 172.102(~)(7) for the hazardous material it contains. Fitted\nwith structural equipment, mountings, or accessories to facilitate mechanical handling, this\ntank is typically used for intermodal and international transport. See \"Intermodal portable\ntank,\" \"Portable tank,\" and \"UN portable tank\" under 5 171.8. After January 1,2003, all\nnewly manufactured portable tanks must conform to the requirements for the design,\nconstruction, and approval of UN portable tanks specified in $9 178.273, 178.274,\n178.275, 178.276, 178.277, and 49 CFR Part 180, Subpart G. See 5 173.32(~)(2). The\nHMR prescribe additional requirements for the use of DOT specification and UN portable\ntanks in 4 173.32.\nYou state you are considering transporting \"UN 2586, Alkyl sulfonic acids, liquid, 8\n(corrosive), PG 111\" in an IS0 tank. Please note that Column 7 of the Hazardous Materials\nTable (HMT; 5 172.10 1) for this material requires you to use a tank that conforms to the\n\n<<<PAGE 2>>>\n\nminimum shell thickness and maximum degree of filling requirements prescribed in\nSpecial Provisions T4 and TP 1, respectively. See 8 $ 172.102(~)(7)(ii) and (c)(8)(ii), and\n178.274(d)(2).\nI hope this satisfies your request.\nHattie L. Mitchell, Chief\nRegulatory Review and Reinvention\nOffice of Hazardous Materials Standards\n\n<<<PAGE 3>>>\n\nAmerican Metals & Chemical Corporation\nOctober 15,2007\nMr. Charles A. Hockman, Director\nOEce of Hazardous Materials Technology\nPipeline of Hazardous Safety Administration\nUS Department of Transportation\n1200 New Jersey Avenue SE\nRoom E2 1-3 12\nWashington, D.C. 20590-0001\nDear Mr. Hockman:\nWe are contemplating the import of a Class 8 Corrosive (UN 2586) in IS0 Containers\nholding approximately 5,000 gallons. I'm confident that your office is familiar with these\ncontainers. They're stainless steel tanks supported within a steel fiame and are certified\nfor the transport of corrosives. All sides of the tank are visible through the fiame.\nA question has arisen with a USA inland carrier as to the markings required on the IS0\nContainer. The carrier contends that these are \"portable tanks\" and are therefore required\nto be marked as set forth in Title 49 CFR 172.326. We contend that these are \"cargo\ntanks\" and are therefore required to be marked as set forth in Title 49 CFR 172.328 .\nWe respectfully request an Official Determination and Interpretation from the USA\nDepartment of Transportation as to whether an IS0 Container is a \"portable tank\" or a\n\"cargo container\" and as to whether required markings must be as per CFR 172.326 or as\nper CFR 172.328.\nThank you.\nYours truly,\nCORRESPOIVDENCE\nP.O.
