Items considered Hazardous Materials (HAZMAT) including aerosols and alcohol-based products (e.g., pressurized spray cans, hairspray, nail polish remover, nail polish etc.) are required by the U.S. Department of Transportation to be shipped by Ground-only transport, due to air transport restrictions and regulations. For these shipments, we recommend UPS Ground. USPS Ground is also an option for shipments in the continental United States. For P.O. Box addresses, USPS Ground (Parcel Post) is the only shipping method available. Regrettably, these items cannot be shipped to Alaska, Hawaii, or Puerto Rico.
