This brochure is written to raise awareness of hazardous materials shipping requirements among small and entry-level hazardous materials shippers who may not be aware of the Hazardous Materials Regulations. Created in partnership with the Council on the Safe Transportation of Hazardous Articles (COSTHA) and the Associated Mail and Parcel Carriers (AMPC), this brochure addresses a growing community of small shippers, which has burgeoned in size since the introduction of online auction websites.
