No. 05-0224 413 No. Pearl Street Albany, NY 12207 Dear Mr. Regan: This is in response to your request for clarification of the requirements under the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180) pertaining to hazardous materials authorized to be transported under the proper shipping name "Consumer commodity." Specifically, you ask whether "Methyl methacrylate monomer, stabilized," UN1247 and "Ethyl methacrylate, stabilized," UN2277 may be transported as "Consumer commodity," ORM-D. The answer is yes, provided certain conditions are met. For the entries "Methyl methacrylate monomer, stabilized," UN1247 and "Ethyl methacrylate, stabilized," UN2277, § 173.150 is referenced in Column (8A) of the Hazardous Materials Table (HMT). Section 173.150 authorizes UN1247 and UN2277 to be renamed "Consurner commodity" and reclassed as ORM-D provided the packages meet the limited quantities provisions in § 173.150(b) and are consumer commodities as defined in § 171.8 (see § 173.150(c)). Therefore, if the inner packages for your Packing Group II materials are not over 1.0 liter (0.3 gallon) net capacity each and are suitable for sale in retail outlets, requirements of Subpart B of Part 173. In addition to the exceptions in § 173.150(b), ORM-D materials are not subject to substance, hazardous waste, marine pollutant, or is offered for transportation and shipping paper requirements unless the material meets the definition of a hazardous 172.101 172.150 050224#

ORM-D materials are also eligible for the exceptions provided in commodity" entry (see § 172.101(b)(3)). I hope this information is helpful. Should you have additional questions, please do not hesitate to contact this office. Sincerely, Hattie L. Mitchell Chief, Regulatory Review and Reinvention Office of Hazardous Materials Standards#
