How Tariffs Are Affecting Trucking Costs in 2026
The 25% Section 232 tariff on Class 3 through Class 8 trucks and parts imported from Mexico took effect November 1, 2025. Since then, the cost of buying, repairing, and insuring a truck has moved in the same direction: up. Here is a clear-eyed look at where tariffs are hitting trucking operations hardest and what carriers can do to manage the exposure they can control.
The Numbers Behind the Noise
Nearly 50% of Class 8 trucks sold in the United States are imported from Mexico, and 43% of all truck parts come from foreign suppliers. When a 25% tariff lands on that supply chain, the math is straightforward even if the full impact takes time to work through production cycles and dealer inventory.
The American Trucking Associations estimates new truck prices could increase by $35,000 per vehicle under the current tariff structure. ACT Research projects a more moderate increase of approximately $10,000 per truck in 2026, reflecting the fact that USMCA-compliant vehicles are partially exempt and tariffs apply only to non-U.S. content. S&P Global Mobility estimates the net impact could reach 9% on new truck prices, potentially reducing Class 8 demand by as much as 17%.
Even at the lower end of those projections, the compounding effect is significant for operations already running on thin margins. Carriers that budgeted $180,000 to $200,000 for a new Class 8 in 2024 are now looking at $190,000 to $235,000, depending on the truck, the manufacturer's sourcing exposure, and how much of the tariff has been passed through rather than absorbed.
Where Tariffs Are Hitting Trucking Operations
New Truck Prices
The most direct and visible impact is on new equipment costs. Most truck manufacturers have supply chains that run through Mexico, and they have passed through varying amounts of the tariff increase depending on their USMCA compliance levels and competitive positioning.
Some OEMs have restructured sourcing to reduce tariff exposure, while others have absorbed part of the increase. None have absorbed all of it.
The timing is particularly difficult for fleets trying to execute a pre-buy ahead of EPA 2027 emissions standards. As covered in our post on EPA 2027 emissions standards, the pre-buy window for 2026 model year trucks is narrowing fast, and tariff-driven price uncertainty on 2027 models makes the cost comparison harder to pin down. Carriers trying to decide between a 2026 pre-buy and waiting for 2027 are doing that math in a volatile environment.
Parts and Maintenance Costs
The 25% tariff on truck parts hits maintenance budgets in ways that compound over time. Steel and aluminum tariffs affect a broad range of components, including frames, axles, suspension parts, and cab components. Many of these parts are sourced from Mexico or contain significant imported materials, even when final assembly happens domestically.
In practice, carriers are seeing parts price increases that range from modest to significant, depending on the component and the supply chain exposure behind it. Tires, which are heavily imported, have seen meaningful price increases. Brake components, engine parts, and electronics have also seen varying degrees of cost pressure. For fleets that run high mileage and consume parts quickly, the cumulative impact is material.
The maintenance math also affects the pre-buy or hold decision. A carrier running a high-mileage 2020 or 2021 truck might ordinarily trade it in. But if parts prices are up and used truck values have held, running the current truck longer while paying higher maintenance costs may still pencil out better than buying new at a tariff-inflated price.
Freight Volumes and Rates
Tariffs affect not only what it costs to run a truck, but also how much freight is available to haul. When tariffs raise the price of imported consumer goods, demand tends to soften. That can mean fewer containers at ports, fewer loads moving from distribution centers, and more competition for available freight on domestic lanes.
The short-term picture has been mixed. Cross-border freight between the U.S. and Mexico saw significant volatility in the first quarter of 2026, with northbound rates out of Laredo and El Paso jumping 15% to 25% during the IEEPA-to-Section 122 tariff transition.
Domestic lanes have felt the indirect effects of border-lane disruptions, particularly in Texas and Michigan. DAT data showed spot van rates reaching $2.41 per mile by late February 2026, the seventh straight monthly gain, with spot rates running 20% or more higher year over year in early February.
For carriers that do not run cross-border freight, the tariff impact on rates is more indirect, but it is still real. When Laredo northbound rates spike, Dallas to Houston backhaul rates adjust. When Detroit cross-border volumes surge, the entire I-94 corridor tightens. The freight network is connected, and border volatility ripples through domestic lanes.
Insurance Costs
Insurance is the cost driver in trucking that rarely gets attributed to tariffs in carrier analysis, but the connection is direct. Higher truck values mean higher stated values on physical damage policies, which leads to higher physical damage premiums. A truck that cost $180,000 in 2023 and now costs $210,000 because of combined tariff and EPA transition effects needs a stated value update, and that update increases the premium proportionally.
Tariff-driven parts inflation also affects claims costs. Those claims costs flow into insurer loss ratios, and loss ratios flow into premium increases at renewal. Commercial auto insurance premiums were already rising above pre-pandemic levels entering 2026. Insurance was the second major cost pressure for fleets according to CCJ's State of Freight analysis, and tariff-driven truck value increases are adding to that pressure. As covered in our guide on how trucking insurance rates are calculated, vehicle value is one of the most direct inputs to physical damage premium calculations. An accurate stated value is not optional — it is the number that determines your payout in a total loss.
Extended Replacement Cycles
When new trucks cost significantly more, carriers often extend replacement cycles and keep equipment on the road longer than they otherwise would. That decision has compounding effects. Older trucks carry higher maintenance costs, face more frequent breakdowns, and are more likely to generate roadside inspection violations that affect CSA scores. A fleet that ordinarily replaced trucks at 500,000 miles and now runs them to 700,000 miles is making a different maintenance and compliance bet than its previous operating model assumed.
Extended replacement cycles also affect physical damage coverage decisions. The relationship between a truck's stated value and its actual condition matters more as the truck ages and mileage increases. An aging truck that was stated at $120,000 two years ago and is now worth $85,000 at ACV may be misvalued in the policy, in either direction. Get your values reviewed before renewal.
What Carriers Can Actually Control
Tariff policy is not something individual carriers control. The cost pressure it creates is real, and it will not resolve quickly. What carriers can control is how their operation is positioned to absorb it:
- Know your cost per mile accurately. KCH Transport noted in late 2025 that most carriers needed at least $1.80 per mile just to break even, yet many lane rates averaged $1.69 per mile. In a tariff-pressured environment, the gap between your actual cost per mile and your minimum rate floor is the number that matters most. Set it based on current costs, not 2023 costs.
- Update your stated values before renewal. If you have purchased equipment in the last 12 to 18 months, whether a 2026 pre-buy or a used truck at elevated values, make sure your physical damage policy reflects what the truck is actually worth today.
- Review your parts and maintenance budget. If you have not updated your maintenance cost assumptions since before November 2025, your operating cost model is understating your actual exposure.
- Monitor cross-border lane volatility. Even if you do not run Mexico freight, your lanes may be affected by border disruptions. Understanding which of your corridors have indirect tariff exposure helps you price loads more accurately.
- Track the legislative calendar. The Section 122 tariff provisions had a 150-day clock that expired in mid-July 2026. What replaces them, whether higher, lower, or different tariff structures, will shape equipment and operating costs for the rest of 2026 and into 2027.
The Insurance Review You Should Be Having Right Now
Between tariff-driven equipment price increases and EPA 2027 transition costs, the value of equipment in most commercial trucking fleets has changed materially in the last 12 to 18 months. Physical damage policies that were accurate in early 2025 may now significantly undervalue equipment purchased or revalued since then.
An undervalued stated value does not protect you with a lower premium — it pays out less when you have a total loss. That gap is the carrier's problem, not the insurer's. At Marquee Insurance Group, we work with carriers to make sure coverage reflects what the equipment is actually worth today, not what it was worth when the policy was last reviewed.
