Hazmat freight is not inherently harder to haul. What makes it different is that the paperwork is graded pass/fail. A shipment with a missing UN number or an unsigned certification does not get a warning — it gets refused at the dock, or worse, cited at a roadside inspection with the shipper named on the violation.
Here is what South Florida shippers need to have in order before hazardous materials go on a truck.
Know which hazard class you are shipping
The U.S. Department of Transportation groups hazardous materials into nine classes. Most commercial LTL shippers only ever touch three or four of them:
- Class 3 — Flammable liquids. Paints, solvents, adhesives, some cleaning products, many cosmetics.
- Class 8 — Corrosives. Battery acid, pool chemicals, industrial cleaners.
- Class 9 — Miscellaneous. Lithium batteries, dry ice, environmentally hazardous substances. This is the class that catches e-commerce shippers off guard.
- Class 2 — Gases. Aerosols, compressed gas cylinders, refrigerants.
Your safety data sheet has the answer. Section 14 of every SDS lists the proper shipping name, UN identification number, hazard class, and packing group. If you are guessing at any of those four, stop and read the SDS — that is exactly what it is there for.
Limited quantity and ORM-D
Small inner packagings of certain materials can ship under limited quantity provisions with reduced marking and documentation requirements. This is why a case of aerosol cans can move more simply than a drum of the same product. It is a genuine relief, but the exception has conditions on inner package size and total package weight, and it does not remove the requirement for proper packaging and marking.
The four things that must be right
1. Packaging
Most hazmat requires UN-specification packaging — containers tested and certified for the material, marked with a UN code on the box or drum. Reusing an unmarked carton because it is the right size is a violation even if nothing leaks. Absorbent, cushioning, and closure instructions from the packaging manufacturer all have to be followed.
2. Marking and labeling
Each package needs the proper shipping name, the UN number, and the diamond-shaped hazard label for its class. Orientation arrows are required for liquids in certain configurations. Old labels from previous shipments must be removed or fully obscured — a box showing two different hazard classes will be rejected.
3. Shipping papers
The bill of lading must show the basic description in the correct sequence: UN number, proper shipping name, hazard class, packing group. It also needs the total quantity, the number and type of packages, an emergency response telephone number that is monitored while the shipment is in transit, and a signed shipper certification. Missing the emergency contact number is one of the most common reasons a hazmat load is turned away.
4. Placards
Placarding is the carrier’s responsibility, but it depends on what you declare. The carrier decides placarding from your shipping papers, so an inaccurate description puts the driver in violation. If you ship hazmat regularly, keep placards available for the carrier — the shipper is required to provide them in many situations.
Employee training is not optional
Anyone who prepares, offers, or handles hazardous materials for transport is a “hazmat employee” under federal rules and must be trained and re-trained on a recurring cycle, with records kept. This applies to the person taping the box, not just the compliance manager. Small shippers routinely miss this until an audit finds it.
Choosing a carrier in South Florida
Not every LTL carrier accepts hazmat, and among those that do, not every driver is endorsed. Ask three questions before you tender:
- Are your drivers hazmat-endorsed, and is the endorsement current?
- Which classes will you accept, and are there commodities you refuse?
- Do you carry placards on the truck, or do I need to supply them?
Go LTL runs hazmat-endorsed drivers across Miami-Dade, Broward, and Palm Beach as part of our regular LTL and courier fleet. Because our drivers are also TSA-approved and bonded, a hazmat shipment heading to Miami International Airport or moving in bond from a port does not need to change hands mid-route. For freight that needs to stage before it moves, our yard storage and container freight station handle the intermediate steps.

Frequently asked questions
Do I need a hazmat certification to ship hazardous materials?
You do not need a personal license, but federal rules require that every employee who prepares or offers hazmat for transport receives function-specific hazmat training, with documented records and periodic retraining. The obligation sits with the employer.
Can hazmat move on a regular LTL truck with other freight?
Usually yes, as long as the materials are compatible and segregation requirements are met. Certain combinations of hazard classes cannot be loaded together, which is one reason accurate shipping papers matter — the carrier uses them to plan the load.
Are lithium batteries considered hazmat?
Lithium batteries are regulated under Class 9, with different requirements depending on whether they ship alone, packed with equipment, or installed in equipment. Watt-hour rating and quantity affect which provisions apply, so check the current requirements for your specific battery before shipping.
