Shipping Hazardous Materials

Why Proper Hazardous Material Classification Matters

Proper classification is the foundation of compliant hazardous material shipping. Before freight can be packaged, labeled, or transported, shippers must identify the correct Proper Shipping Name, UN identification number, hazard class, and packing group. These classifications determine how the shipment must be packaged, documented, and handled throughout transit.

Errors in classification can lead to shipment delays, rejected freight, regulatory fines, and increased safety risks. Incorrect information may also prevent carriers from accepting a shipment or require costly corrections before transportation can continue.

Hazardous materials often have different requirements depending on whether they are transported by truck, rail, air, or ocean. Verifying shipment details before pickup helps ensure compliance with applicable regulations while reducing disruptions across the supply chain.

By establishing consistent classification procedures and reviewing shipment information before tendering freight, businesses can improve safety, reduce costly mistakes, and keep hazardous shipments moving efficiently.

What are Hazardous Materials?

Hazardous materials include materials designated by the Secretary of the Department of Transportation (DOT) as posing an unreasonable threat to the public and the environment. This term applies to things like hazardous substances and wastes, marine pollutants, and elevated-temperature material.

HAZMAT Classifications

Hazardous materials take many forms. These are nine classes of HAZMAT you need to be aware of:

Class 1 – Explosives: Materials that could potentially explode or burst into flames while in transit if not handled properly.

Class 2 – Gases: Including flammable, non-flammable, and poisonous or toxic gases. They can compress, dissolve under pressure, pressurize, or exist as cryogenic liquids and liquified gases.

Class 3 – Flammable Liquid: Including materials that have a flash point (FP) not more than 141 degrees Fahrenheit.

Class 4 – Flammable Solids: Including flammable solids and spontaneously combustible material or materials that are dangerous when wet.

Class 5 – Oxidizing Substances; Organic Peroxides: Includes things like oxidizer and organic peroxide.

Class 6 – Poisonous (Toxic) and Infectious Substances: Including materials with poisonous or toxic properties, as well as infectious substances.

Class 7 – Radioactive Material: Anything that is radioactive.

Class 8 – Corrosives: Anything that could cause corrosion.

Class 9 – Miscellaneous Dangerous Goods: Including things like environmentally hazardous substances, elevated temperature material, hazardous wastes, and marine pollutants.

ORM-D – Materials classified as consumer commodities that may be subject to the regulations but presents a limited hazard during transportation due to their form, quantity, and packaging.

Common Hazmat Shipping Mistakes

Many hazardous material shipping issues stem from preventable mistakes. Taking time to verify shipment information before pickup can help avoid delays, fines, and rejected freight.

Common mistakes include using the wrong Proper Shipping Name or UN identification number, selecting an incorrect hazard class, applying missing or inaccurate labels, and using packaging that does not meet regulatory requirements. Incomplete shipping papers, outdated employee training, and missing emergency response information can also create compliance issues.

Working with carriers that are not authorized or properly equipped to transport hazardous materials may result in shipment refusals or transportation delays.

Developing standardized shipping procedures and reviewing documentation before every shipment helps reduce these risks. A thorough pre-shipment review improves compliance, supports safer transportation, and minimizes costly disruptions throughout the supply chain.

Shipper’s Responsibilities in Hazmat Shipping

HAZMAT shippers have many responsibilities according to federal regulations. Recognizing that the goods you are shipping are hazardous materials is the first and most difficult step. Proper classification of hazardous materials is essential as well. This determines how to label, package, and handle the goods while in transit. These are critical to safe passage.

Shipper responsibilities include:

Determining whether a material meets the definition of a “hazardous material”: This is the first and most important step.

Proper Shipping Name, Class/Division, and Identification Number: These must be included on the shipping documents.

Hazard Warning Label: I­­t’s essential that all hazardous materials be properly labeled when prior to shipment.

Packing: Shippers must use authorized packaging that has been manufactured, assembled, and marked in accordance with the Hazardous Materials Regulations (HMR).

Marking: Basic marking requirements for hazardous materials consist of a proper shipping name and identification number for the contents of the package. It is important that the markings be durable, in English, and not obscured by other labels or markings on the package.

Employee Training: Mandate HAZMAT training for all personnel handling hazardous materials, aimed at enhancing overall understanding and compliance with regulations and documentation. Additionally, ensure specialized, safety, and security training as mandated by federal regulations. Employees must undergo refresher training every three years or upon job function alteration.

Security Plans: Hazardous Materials Regulations (HMR) dictate that each hazmat employer that is subject to the security plan requirements must establish and implement a security plan and train their HAZMAT employees on the plan.

Shipping Papers: Shippers must create documents for the purpose of communicating that the shipment contents are hazardous. These documents must include a proper description of the hazardous materials that comply with the regulatory requirements. They must include details like proper shipping name, hazard class, identification number, and packaging group. Carriers must not transport HAZMAT without properly preparing shipping documents.

Emergency Response Phone Number and Information: Include an emergency response phone number on the shipping papers. Ensure continuous monitoring of this number throughout the material’s transportation. The number must connect to a person knowledgeable about the hazardous materials being shipped and the appropriate emergency response procedures. If the contact person does not have this knowledge, they need to have immediate access to a person that possesses this knowledge. It’s important to note that the person who signs the shipping papers should be the individual most familiar with the shipment.

Shipper Responsibilities Shared with Carriers

Some carrier responsibilities overlap with shipper responsibilities, making the carrier ultimately responsible for performing that function in accordance with federal hazardous materials regulations.

These shared responsibilities include shipping papers, compatibility, blocking and bracing, placarding, and security plan preparation.

Ensuring Safety When Shipping Hazardous Material

Ensuring the proper identification and classification of hazardous materials before shipment is crucial for both human and environmental safety. This step directly impacts your ability to adhere to packaging, labeling, and other regulatory mandates necessary for the secure transportation of hazardous goods.

Navigating HAZMAT shipping is intricate and poses risks if mishandled. Thus, it’s paramount to choose a shipping partner with the expertise and qualifications to transport hazardous goods safely. Entrusting your shipments to HAZMAT shipping experts simplifies the process and guarantees the safe arrival of your goods at their destination.
