Knowing the ins and outs when transporting diesel
If you work with heavy equipment or vehicles, it's likely they run on diesel fuel. You probably already know that driving these machines to the nearest gas station isn't practical. So, what's the solution? The simplest approach is to bring the diesel fuel directly to your equipment.
Transporting diesel fuel raises a lot of questions about it being regulated as hazmat and the requirements for placarding. This guide provides an overview of what to look out for when transporting diesel fuel, ensuring compliance with the Hazardous Materials Regulations (HMR). Let’s take a closer look at what you need to look for.
Bulk and non-bulk packaging
Understanding the difference between bulk and non-bulk packaging is important when you are transporting diesel fuel because it can determine if the HMR applies or not.
Bulk packaging: This type of packaging does not have an intermediate form of containment and has a capacity greater than 119 gallons for a liquid hazardous material (hazmat). Bulk packages are easily recognizable because of their size and include IBCs, cargo tanks, and portable tanks.
Non-bulk packaging: This type of package has a maximum capacity of 119 gallons or less. Non-bulk packages are smaller and can easily fit into other packages or vehicles and include bottles, buckets, and drums.
The key here is the CAPACITY of the packaging, not how much liquid is in the packaging. For example, if you have a 250-gallon IBC but only have 20 gallons of liquid inside the IBC, it’s still a bulk packaging and you need to follow the requirements for bulk packages regardless of how much liquid is inside.
Reclassifying diesel
Diesel fuel is normally classified as a Class 3 flammable liquid in the HMR. However, diesel fuel can also be reclassified as a combustible liquid. According to 49 CFR 173.150(f), a flammable liquid with a flash point at or above 100º F (38º C) that does not meet the definition of any other hazard class may be reclassified as a combustible liquid.
Reclassifying diesel fuel as a combustible liquid does offer some advantages:
- Non-bulk packaging: 49 CFR 173.150(f)(2) says that “the requirements of this subchapter do not apply to combustible liquids in non-bulk packaging.” That means diesel fuel in non-bulk packaging is not regulated by the HMR and is essentially considered general cargo. Meaning the following are not required: specification packaging, markings, labels, placards, or hazmat shipping papers.
- Bulk packaging: Unfortunately, bulk packages of combustible liquids don’t have the same exemptions as non-bulk combustible liquids. However, bulk packages of combustible liquids are exempt from the security plan requirements of the HMR.
When to placard
Placarding requirements can depend on several factors such as hazard classification, package size, and total quantity.
For non-bulk packages of diesel fuel that haven’t been reclassified to a combustible liquid, placarding is required when the total weight of diesel fuel in non-bulk packages meets or exceeds 1,001 pounds. If your diesel fuel in non-bulk packages has been reclassified to a combustible liquid, then placards are not required because combustible liquids in non-bulk packages are not subject to the HMR, 173.150(f)(2).
Placards are always required for diesel fuel in bulk packages. With that said, if your diesel fuel has been reclassified to a combustible liquid, you have the option to use the all-red placard or the red placard with a white bottom. If you are transporting combustible liquids by rail, you must use the red placard with the white bottom. If your diesel fuel has not been reclassified, then you must use the all-red placard.

Key to remember: Ensure you understand the difference between bulk and non-bulk packages of diesel fuel. Reclassifying your non-bulk packages of diesel fuel to a combustible liquid exempts you from the requirements of the HMR.
