No. 04-0231\nSenior Consultant\n101 Center Pointe Drive\nEnvironmental Resource Center\nCary, North Carolina 27513\nDear Ms. Knight:\nThis responds to your September 7, 2004 letter requesting clarification on marking and\nshipping paper requirements under the Hazardous Materials Regulations (HMR; 49 CFR\nParts 171-187). Specifically, you ask for an explanation of the marking and shipping paper\nrequirements for a hazardous materials shipment containing two or more inner packagings of\ndifferent but compatible hazardous materials packed together in the same outer package.\nYou describe the following scenario: a package contains the following inner packagings- a\n1-gallon glass bottle of benzene, a 1-gallon glass bottle of acetone, a 1-gallon glass bottle of\nethanol, and a 4-ounce plastic bottle of elemental mercury. It is your understanding that the\nouter package must bear the proper shipping names and identification numbers for each\nhazardous material in the inner packagings. It is also your understanding that the shipping\npaper must include a separate basic description for each hazardous material in the inner\npackagings.\nYour understanding is correct. Section 173.24(e) authorizes the shipment of a mixed content\nof hazardous materials in the same outer package provided the hazardous materials are\nmarked with the proper shipping name and identification number and labeled in accordance\ncompatible and will not react dangerously with each other. The outer package must be\nwith Subpart E of Part 172 for each hazardous material contained therein.\nIn addition, each hazardous material packaged in the outer package must also be properly\ndescribed on the shipping paper in accordance with Subpart C of Part 172, including the\nnumber and type of packagings.\nI hope this arıswers your inquiry.\nChief, Standards Development\nOffice of Hazardous Materials Standards\n173.24(E)\n040231\n\n<<<PAGE 2>>>\n\nENVIRONMENTAL RESOURCE CENTER®\n101 Center Pointe Drive, Cary, North Carolina 27513 (919) 469-1585\nBoothe\nMarkus\n§173-241\nSeptember 7, 2004\nMarking * Shipping Paper?\n04-0231\nMr. Edward Mazzullo\nDirector for the Office of Hazardous Materials Standards\n400 7' S:reet SW\nUS DOT RSPA (DH M10)\nWashington, DC 20590-0001\nDear Mr Mazzullo,\nAccording to 49 CFR 172.404(b), when two or more packages containing compatible\ncontainer or overpack must be labeled as required for each class of hazardous material\nhazardous material are placed within the same outside container or overpack, the outside\ncontained therein.
