North Dakota does not require a special permit to haul hazardous materials within the state. However, federal rules (which apply in ND) require commercial operators and hauler of hazardous materials must have current Certificates of Registration as outlined in the Code of Federal Regulations (CFR).
Federal regulations also require a safety permit for interstate or intrastate transportation of certain radioactive, explosive, or poisonous materials, view details in the CFR, Title 49.
