Specifically, you ask whether a cylinder may have a marking with the proper shipping\nname of “UN1075, Petroleum gases, liquefied, 2.1,” as well as a secondary marking of “Butane.”\nIn accordance with 49 CFR 172.301(a)(1), each person who offers a hazardous material for\ntransportation in a non-bulk packaging must mark the package with the proper shipping name\nand identification number for the material contained within, as shown in the § 172.101\nHazardous Materials Table. However, special provision 19 permits use of the identification\nnumber “UN1075” in place of “UN1011” for butane in domestic transportation only. Based on\nthe information provided in your email, your hazardous material may be described and marked\nas either “UN1075, Petroleum gases, liquefied, 2.1,” or “UN1075, Butane, 2.1.” The\nidentification number used must be consistent on package markings, shipping papers, and\nemergency response information.\nWhile the HMR do not prohibit the inclusion of “Butane” as a secondary marking in addition to\nthe proper shipping name of either “UN1075, Petroleum gases, liquefied, 2.1,” or “UN1075,\nButane, 2.1,” this may cause confusion in transportation and result in the frustration of your\nshipment.\nI hope this information is helpful. Please contact us if we can be of further assistance.\nSincerely,\nT. Glenn Foster\nChief, Regulatory Review and Reinvention Branch\nStandards and Rulemaking Division\n\n<<<PAGE 2>>>\n\nBallengee\n21-0090\nFrom: INFOCNTR (PHMSA)\nTo: Hazmat Interps\nSubject: FW: Interpretation on LPG Cylinder labeling\nDate: Wednesday, September 8, 2021 4:38:29 PM\nAttachments: image.png\nBelow is a request for letter of interpretation.\nThanks,\nJonathon, HMIC\nFrom: Justin@HPG <justin@highprecisiongas.com>\nSent: Wednesday, September 8, 2021 3:57 PM\nTo: INFOCNTR (PHMSA) <INFOCNTR.INFOCNTR@dot.gov>\nSubject: Interpretation on LPG Cylinder labeling\nCAUTION: This email originated from outside of the Department of Transportation (DOT).
