Red-Dyed Diesel Gets Federal Approval: What Truckers Need to Know
A new federal executive order temporarily opens the door for red-dyed diesel to be used on public highways, while directing the Treasury Department to defer certain federal diesel excise-tax obligations. Trucking and fuel industry groups are cautioning carriers to wait for final Treasury and IRS guidance before purchasing or using dyed fuel for on-road operations.
Order Targets Diesel Costs
President Donald Trump signed the order in an effort to reduce fuel costs for truckers, farmers, construction operators and other diesel users. The order directs the Treasury Department to defer payment of the federal excise tax imposed on dyed diesel used on public roads and to examine options for eliminating some of the deferred tax obligations.
Trump said a typical trucker could save more than $100 when refueling. The actual savings will depend on fuel prices, tank capacity, applicable taxes and whether the fuel purchase qualifies under the final federal rules.
The authorization is temporary. The material describing the order references both use through the end of 2026 and a deferral covering the remainder of the year, making additional Treasury and IRS guidance necessary to establish the effective dates and procedures.
Red-Dyed Diesel Remains Identifiable
Dyed diesel is generally the same base fuel as clear diesel, but it contains a concentrated chemical marker used to identify fuel intended for off-road purposes. According to the Nevada Trucking Association, Solvent Red 164 is added at a level that allows inspectors to detect the dye even after the fuel has been diluted with clear diesel.
IRS Publication 510 states that qualifying dyed fuel generally is exempt from the regular federal diesel excise tax. However, the fuel ordinarily remains subject to the 0.1-cent-per-gallon Leaking Underground Storage Tank tax.
Carriers Await Tax and IFTA Guidance
The temporary suspension of enforcement on public highways does not by itself resolve how carriers should report fuel purchases. The federal excise tax is not reported on an International Fuel Tax Agreement return, and carriers will need clear instructions on how dyed-fuel purchases, deferred taxes and state fuel-tax obligations should be handled.
Industry groups are warning that the order does not automatically make every dyed-diesel purchase legal for every truck, location or operation. State requirements may also differ, and the order’s treatment of state fuel taxes remains subject to further guidance.
Carriers should not assume that dyed diesel available at a truck stop’s “reefer” pump is the same as fuel covered by the federal action. Most reefer fuel is not dyed diesel intended for use in highway vehicles.
Industry Questions Remain
The order could reduce fuel costs for qualifying users if the tax deferral is implemented broadly. However, critics have questioned how much the policy will affect retail diesel prices, particularly while fuel prices remain elevated.
Until the Treasury Department and IRS issue final instructions, trucking companies face uncertainty over eligibility, recordkeeping, tax treatment and enforcement. Industry groups are advising members to review the final federal guidance before changing fueling practices.
