DC 20590\nMAY 2 9 2012\nMr. Guy Dalton\nHead of Transport Compliance/Safety\nLinde Gas North America, LLC\n130 Briar Hill\nPainesville, OH 44077\nRef. No. 11-0297 'R\nDear Mr. Dalton:\nThis is a revised response to your December 2, 2011 letter requesting clarification of marking\nrequirements for foreign-made UN cylinders under the Hazardous Materials Regulations\n(HMR; 49 CFR Parts 171-180).\nYour questions are paraphrased and answered as follows:\nQl. Does equal treatment of U.S. manufactured UN cylinders by a foreign competent authority\neliminate the requirement that a UN cylinder approved by a foreign competent authority be\napproved in accordance with the HMR?\nAI. No. Except for UN pressure receptacles marked with the letters \"CAN\" for Canada as a\ncountry ofmanufacture or approval (see§ 171.12(a)(4)(i)); Canadian Transport Commission\n(CTC) specification cylinders (see§ 171.12(a)(4)(ii)); and cylinders under conditional use in\nport areas or for export (see § 171.23(a)(3)), cylinders are not authorized for transportation to,\nfrom, or within the United States unless approved in accordance with the HMR (see§§ 178.69\nthru 178. 71) and marked \"USA\" as the country of approval(§ 171.23(a)(2)(iv)).\nQ2. May a foreign-made UN cylinder be imported into the U.S. that only has the stamp\nmarking of the country of manufacture?\nA2. No. A UN cylinder must also be marked with the country of approval whether the U.S.,\nthe country of manufacture, or another competent authority. As noted in Al, except under\ncertain authorized conditions, cylinders must be approved in accordance with the requirements\nof the HMR and display the \"USA\" marking.\nQ3. If a foreign-made UN cylinder does not conform to the marking of§ 178.7l(p)(3), what\nmechanism should be used to document equal treatment other than the cylinder stamp marking?\n\n<<<PAGE 2>>>\n\nA3. Your question relates to§ 173.24(d) regarding the use ofUN standard packagings (e.g.,\nUN cylinders) manufactured outside the United States. Section 173.24(d)(2) authorizes the use\nofthese packagings under conditions and ·limitations including recognition (equal treatment) of\nUN standard packagings manufactured in the U.S. by the competent authority of the country of\nmanufacture. There is no documentation requirement associated with§ 173.24(d)(2). These\nprovisions neither negate nor supersede the requirements of the HMR for the approval and\ntransport of foreign-made UN cylinders.\nI apologize for any confusion my earlier response may have caused. Ifyou need additional\nassistance, please contact this Office at (202) 366-8553.\nSits~\nBen Supko\nActing Chief, Standards Development Branch\nStandards and Rulemaking Division\n\n<<<PAGE 3>>>\n\nDecember 2, 20 ll\n13 0 Briar Hill\nPainesville, Ohio 44077\n440-354-5614\n440-579-0203\nguy.dalton@linde.com\n.\nJ)e r /t..t n dere Y7\n~II?, . . 7J\n~I tnder.s\nOffice of Hazardous Materials Standards\nPipeline and Hazardous Materials Safety Administration, Attn: PHH-10\nU.S. Department of Transportation, East Building\n1200 New Jersey A venue, SE.\nWashington, DC 20590-0001.\nRequest for Interpretation\nDear Sir or Madame,\nLinde Gas North America LLC (Linde) is requesting interpretation and guidance regarding the use of foreign\nmanufactured UN cylinders in the US.\n49CFR171.23(2)(iv) allows the importation of UN cylinders marked with \"USA\" as the country of approval in\naccordance with 178.69 and 178.70 when prepared in accordance with the ICAO technical instructions. llowever,\n173.24(d)(2)(iii) indicates that import/export ofUNcylinders is allowed if the competent authority of the country of\nmanufacture allows for reciprocal treatment of the UN package.\n• Clarification is requested regarding the reciprocal treatment, specifically, does such reciprocal treatment\npreclude or eliminate the requirement that the UN cylinder have both the export country's, and the \"USA\"\nauthorization stamp marking as required in 178.71(p)(3) to be imported, transported and used in the USA?\n• May a cylinder be imported into the USA that only has the stamp markings ofthe country of manufacture?\n• If the cylinder is not marked as required in l78.7l(p)(3), what is the required mechanism to document\nreciprocal treatment other than the cylinder stamp marking?\nA written response at your earliest convenience is appreciated.\nSincerely\n11-02.~7\nGuy Dalton\nHead of Transport Compliance/Safety\nLinde Gas North America LLC\n440-251-0303\nguy.dalton@linde.corn\nLinde Gas North America LLC","truncated":false,"body_characters":4583}
