The Ultimate Guide to Hazmat Freight Shipping

17 Mar 2026

Share on:

Hazardous material shipping, also known as Hazmat shipping, is the most critical aspect of transporting dangerous goods. Whether it’s organic chemicals or lithium-ion batteries, understanding the rules and regulations regarding hazmat shipping is necessary for businesses and professionals who transport hazardous materials.

What is Included in Hazmat Shipping?

Hazmat shipping refers to the transportation of materials that are risky for health, safety, and the atmosphere. In the United States of America, hazardous materials include lithium batteries, corrosive or flammable materials like chemicals & paint, aerosols & fragrances, and dry ice.

Shipping these materials in a safe way requires adherence to regulations set by the Department of Transportation and international organizations. Shippers need to understand the hazard classes 1-9 to ensure they ship hazmat in a safe and secure way.

They also need to use appropriate packing and ensure the carriers are certified.

Essential Steps for Shipping Hazmat in the US

Here are some important steps that you need to follow for hazmat freight shipping:

Classify the Material

Recognize the hazard class and the four-digit UN number(eg, UN1993 for flammable materials). There are nine DOT classes that define everything ranging from explosives to corrosives and lithium batteries.

Ensure Proper Packaging

Use UN-certified packaging that is designed to carry specific materials. Packaging should contain the packing group(I, II, III), indicating the level of danger each packing carries.

Labeling and Placarding

Apply hazard labels on all packages. Vehicles that transport hazardous materials should display placards on all four sides.

Documentation

Keep the shipping papers prepared. These papers should include a hazardous material declaration, emergency contact information, and a Safety Data Sheet(SDS).

Choose the Right Carrier

Make sure the carrier you choose for shipping hazmat is certified to handle a specific class of hazardous materials being transported.

What are the Products Classified as Hazmat?

According to the US Department of Transportation, Hazmat is defined into nine different classes:

  • Class 1(Explosives): 

They are defined as products that are prone to exploding under specific conditions. They include gunpowder, fireworks, and ammunition.

  • Class 2(Gases): 

Classified as products containing either toxic, flammable, or explosive gases, including products like aerosols, lighters, and fire extinguishers.

  • Class 3(Flammable Liquids): 

Defined as liquids that ignite when exposed to an open flame. This class includes products like gasoline, paint thinner, and nail polish.

  • Class 4(Flammable Solids): 

It includes materials classified as solid substances that can ignite when exposed to an open flame, such as matches, sulfur, and coal.

  • Class 5(Oxidizing Substances): 

Designated as materials prone to causing explosions due to large amounts of oxygen that cause reaction, such as chlorine, bleach, and ammonium nitrate fertilizers.

  • Class 6(Toxic/Infectious Materials): 

They’re classified as substances that can cause injury, harm, or death when inhaled. They include biomedical waste, pesticides, and arsenic.

  • Class 7(Radioactive Material): 

Listed as materials that can spontaneously spread around and give off ionizing radiation. These include radioactive medicines, depleted uranium, and X-ray machines.

  • Class 8(Corrosives): 

Classified as corrosive materials that can cause damage when they contact human skin or property. These include sulfuric acid, hydrochloric acid, and paint stripper.

  • Class 9(Miscellaneous Hazard Materials): 

Defined as materials or products considered unsuitable for any other class. Still, this class of materials is dangerous when shipped, and includes products like dry ice, electric vehicles, and lithium-ion batteries.

What are the Responsibilities of the Shipper?

The responsibilities of a shipper shipping hazmat include:

  • Determining if the products they’re shipping are defined as hazardous materials
  • Providing a proper shipping name
  • Determining the division and class of hazardous materials
  • Placing a hazard warning placard everywhere on the shipment
  • Correctly marking the shipment as hazardous
  • Providing hazmat training to the employee handling hazardous materials.
  • Carrying appropriate shipping papers
  • Offering emergency response details
  • Getting IATA certification for handling hazardous materials
  • Properly blocking and covering the shipment
  • Having a security plan in place

What is Included in Hazard Employees Training?

In a hazard employee training program, employees handling hazmat shipping should complete the following tasks and modules:

  1. General awareness and familiarization training.
  2. Function-specific training
  3. Safety training
  4. Security awareness training
  5. In-depth security training, in case there’s a need for a security plan.
  6. Driver training for staff operating a motor vehicle used to transport hazardous goods.
