Ohio Rev. Code § 3743.58
The fire marshal shall adopt rules governing the transportation of fireworks on the highways of this state. These rules shall be substantially equivalent to regulations of the United States department of transportation governing the transportation of fireworks, and to the fireworks transportation provisions of the most recent versions of chapters 1123, 1124, and 1126 of the most recent national fire protection association standards. Fireworks shall be transported on the highways of this state only in accordance with such rules. Such rules shall not require that shipments of fireworks required by this Chapter to be made directly out of state be made solely by common carriers licensed by the federal government. No requirements of this Chapter that fireworks be shipped or transported directly out of this state require that these shipments be made personally by the seller or solely by common carriers licensed by the federal government.
