The DOT regulates hazardous materials transportation under 49 CFR Parts 100–185. First-time hazmat shippers often underestimate the documentation and packaging requirements — here's a step-by-step guide.
Find your material in the Hazardous Materials Table (49 CFR §172.101). Identify the UN number, proper shipping name, hazard class and division, and packing group (I, II, or III — I is most dangerous).
The packing group determines packaging requirements. All packaging must meet DOT performance specifications — ordinary commercial packaging is not acceptable for most hazmat unless specifically exempted.
Apply the required hazard label (class-specific diamond), mark the proper shipping name and UN number, mark shipper and consignee addresses, and add required orientation markings for liquids.
The hazardous materials shipping paper must include: proper shipping name, hazard class, UN number, packing group, quantity, and emergency response telephone number. It must be immediately accessible to the driver.
Not all carriers are certified for all hazmat classes. Your freight broker must verify the carrier's hazmat endorsement and driver CDL-H certification before dispatch. IZY Logistics pre-screens all carriers for hazmat capability.
