Broad Street, Suite 421 Columbus, OH 43215 Reference No. 22-0008 Dear Mr. Forbes: This letter is in response to your February 4, 2022, email requesting clarification of the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180) applicable to the domestic transportation of “UN1978, Propane, 2.1” as “UN1075, Propane, 2.1” in accordance with Special Provision (SP) 19. We have paraphrased and answered your questions as follows: Q1. You ask whether transporting “UN1978, Propane, 2.1” as “UN1075, Propane, 2.1” in accordance with SP 19 requires a person to indicate on a shipping paper “NONCORROSIVE” or “NONCOR,” “NOT FOR Q and T TANKS,” or would this only be applicable when “UN1075” is described and shipped as “liquefied petroleum gas.” A1. When using the UN identification number “1075” in accordance with SP 19 or otherwise, the marking requirements of § 172.203(h)(2) are applicable. Therefore, shipping papers for applicable packagings must include the words “NONCORROSIVE”, “NONCOR”, or “NOT FOR Q and T TANKS”—as appropriate—in accordance with § 172.203(h)(2). Q2. You ask whether transporting “UN1978, Propane, 2.1” as “UN1075, Propane, 2.1” in accordance with SP 19 requires a person to mark the cargo tank as propane in accordance with § 172.328(b) to match the shipping paper or does the cargo tank have to be marked as liquefied petroleum gas. <<>> A2. When transporting “UN1075, Propane, 2.1” domestically in accordance with SP 19, a person is permitted to mark a cargo tank as either propane or liquefied petroleum gas, provided that the UN identification number is consistent on package markings, shipping papers, and emergency response information as required by SP 19. I hope this information is helpful. Please contact us if we can be of further assistance.

Info Center: This is a request for a written interpretation on the two questions posed below dealing with special provision 19 when transporting propane and using UN 1075 ID Number and markings. 1. When transporting UN1075 propane as allowed by Special Provision 19 am I required to mark the shipping paper per 172.203(h)(2) either non-corrosive / non-corr or Not for Q and T Tanks or does this only apply when UN1075 is shipped as Liquefied Petroleum Gas? 2. When transporting UN1075 propane as allowed by Special Provision 19 does the cargo tank have to be marked Propane per 172.328(b) to match the shipping paper Propane or is it allowed to be marked as liquified petroleum gas?
