The answer is yes, provided that the packaging meets the requirements of the DOT-E 11580 exemption and the UN 1A1 packaging standard in the HMR, in all aspects. I hope this information is helpful. If we can be of further assistance, please contact us. Sincerely, 1 Hatle 7, Michell Hattie L.

Mazzullo (DHM-10) Director, Office of Hazardous Materials Standards Research and Special Programs Administration U.S. Department of Transportation 400 Seventh Street, SW Washington, DC 20590 SUBJECT: dual marking of a packaging Dear Sir: We are a manufacturer of stainless steel cylinders (similar to DOT 4BW cylinders) under DOT-E 11580. These cylinders are frequently used to transport liquid hazardous materials. Because DOT cylinder specifications (or related exemptions) are not necessarily recognized by foreign regulatory agencies (or their inspectors), we would like our cylinders also approved as a UN performance-based non-bulk packaging. We see no reason why this packaging cannot be dual marked as an E 11580 cylinder and a UN1A1 drum provided all the requirements for DOT Spec. 4BW (as amended by the exemption) are met and provided all the requirements for a UNIA1 drum are also met. Our packaging (typically as shown on the attached drawing) meets the standards for steel drums Subpart L of Part 178 of Title 49 of the Code of Federal Regulations and will also be tested in accordance with Subpart M. Also, there does not appear to be any non- bulk packaging authorization for a liquid in Subpart E of Part 173 where a UN1A1 drum is authorized but a specification cylinder is not. In other words, wherever a specification cylinder is authorized, a UNIA1 drum is also authorized. Please indicate if we are correct in our opinion that our packaging can be dual marked as DOT Specification E-11580 cylinder and a ÚNIA1 drum if the respective requirements for each packaging are met.
