No. 10-0265\nDear Mr. Ritchie:\nThis responds to your December 21, 2010 email requesting clarification on the materials oftrade\n(MOT) exception defined in § 171.8 and specified in § 173.6 ofthe Hazardous Materials Regulations\n(HMR; 49 CFR Parts 171-180). Your questions are restated and answered as follows:\nQl.) Maya carrier transport 200 kg of MOT on each vehicle ofa truck and trailer combination, or is\nthe transport as a MOT restricted to 200 kg for the combination?\nAI.) The aggregate gross weight of 440 pounds (200 kg) as described in § 173 .6( d) is that ofthe\nMOT located on the entire motor vehicle, which as defined in § 171.8 is a vehicle, machine,\ntractor, trailer, or semitrailer, or any combination thereof, propelled or drawn by mechanical\npower and used upon the highways in the transportation ofpassengers or property. As such, the\ngross weight ofall MOT in the tractor and trailer(s) attached to a tractor may not exceed 440\npounds (200 kg).\nQ2.) Maya vehicle transport both MOT and other fully regulated hazardous materials?\nA2.) The answer to your question is yes. As indicated in §173.6(e) a MOT may be transported on a\nmotor vehicle with other hazardous materials without affecting its eligibility for exceptions\nprovided by §173.6. The fully regulated hazardous materials must comply with all applicable\nHMR requirements.\nQ3.) If a vehicle transports 200 kg of MOT, and other non-bulk Table 2 hazardous materials\nexceeding the 200 kg limit or otherwise ineligible for the MOT exception, when is placarding of\nthe vehicle required?\n\n<<<PAGE 2>>>\n\nA3.) A vehicle containing a maximum aggregate gross weight of 440 pounds (200 kg) of MOT and\nnon-bulk shipments of other hazardous materials listed in § 172.504 Table 1 or 2 may be\nplacarded as if the MOT were not on the vehicle. For example, if 1,441 pounds ofhazardous\nmaterials which, other than exceeding the 440-pound weight restriction, meet the requirements\nofthe MOT exception are transported by motor vehicle, the first 440 pounds may be transported\nunder the exception; the remaining 1001 pounds is subject to the HMR, as applicable, e.g.,\nplacarding, labeling, marking, etc.\nI hope this answers your inquiry. If you need additional assistance, please contact this office at\n202-366-8553.\nSincerely,\nBP1~~\nBen Supko\nActing Chief, Standards Development Branch\nStandards and Rulemaking Division\n\n<<<PAGE 3>>>\n\nSupko, Ben (PHMSA) .; 11~ ore\nW;n1-eY\"'\n~ 17/· g\nDe~fJ I'nons IMrJ T\nFrom: Ritchie, Mike (DOT) [MichaeI.Ritchie@state.mn.us]\nSent: Tuesday, December 21, 2010 10:49 AM\nTo: Supko.
