No. 98-0366\nMr. Gary C. Rosenfield\nPresident\nAero Tech Consumer Aerospace\n1955 South Palm Street, Suite 15\nLas Vegas, Nevada 89104\nDear Mr. Rosenfield:\nThis is in response to your letter dated November 25; 1998, requesting clarification on the applicability\nof the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180) to your liquid slurry mixture\nand requirements for placarding vehicles carrying Division 1,3 materials.\n• Under 49 CFR 173.22, it is the shipper's responsibility to properly classify a hazardous material.\nBased on the information you provided, we are not able to determine the proper classification. We\nrecommend that you evaluate and test your mixture to determine if it meets the hazard class defining\ncriteria in Part 173. We want to emphasize that if this composition is intended to produce an explosive\nor pyrotechnic effect, it must be evaluated under the provisions in $ 173.56\nIn reference to your question on placarding, a manufacturer carrying Division 1.3 materials in its own or\nrented vehicles in local or intrastate transportation, must placard the transport-vehicle in accordance\nwith 49 CFR 172.504. Effective October 1, 1998, the HMR now apply to both intrastate and\ninterstate transportation of hazardous materials in commerce.\nI hope this answers your inquiry.\nSincerely;\nin thills\nDelmer F.

If so, what would be its proper shipping name, hazard class, UN\nnumber, packing group and label code?\n2. Is a manufacturer required to placard its own or rented vehicles in local or intrastate\ntransportation while carrying division 1.3 materials?\nThank you in advance for your anticipated response.\nSincerely,\nGary C.
