Truck Tariffs and What They Mean for Your Fleet

A 25% Section 232 tariff on medium- and heavy-duty commercial trucks imported from Mexico took effect in November 2025. That matters more than a typical trade policy footnote because of how concentrated Class 8 manufacturing actually is: nearly half of all Class 8 trucks sold in the US come from Mexican plants operated by Daimler Truck, Paccar's Peterbilt, International Motors, and Volvo Group, a group that collectively accounts for essentially all Class 8 sales in the country.

Estimates of the actual per-truck cost impact vary by source but land in a consistent range. ACT Research estimates roughly $10,000 per vehicle in 2026 from tariffs alone. The American Trucking Associations has cited increases of up to $35,000 per vehicle. One industry calculation using a $170,000 pre-tariff truck price puts the post-tariff, post-excise-tax total around $238,000. Some owner-operators are already seeing line-item tariff surcharges of $9,500 or more directly on manufacturer quotes.

A Fleet Advantage survey of 2,500 fleet executives found 45% are undecided on their 2026 truck procurement approach, which is a notable share of the industry essentially in a holding pattern rather than committing to buy or defer. That indecision has a visible effect on the age of the trucks actually on the road: fleets running trucks five years old or older now represent 55% of the market, up from 37% in 2023.

That shift isn't cost-neutral. The same research found 35% of fleets report that running 2019 model-year trucks or older has moderately impacted safety performance, which means the cost of delaying replacement isn't limited to rising maintenance bills, it shows up in the safety profile of the fleet too.

Tariff costs change the math on when to replace a truck, but they don't remove the underlying tradeoff: an aging truck still costs more to maintain, still has a worse safety and fuel-efficiency profile than a new one, and still eventually needs replacing regardless of what a new one costs today. What's changed is that the breakeven point on that tradeoff has moved, not that the tradeoff itself has disappeared.

That's exactly the kind of decision that benefits from real data instead of a gut call. Engine-hour and maintenance-cost data from a fleet's existing telematics platform gives a factual basis for which specific vehicles are actually costing the most to keep running, so a fleet extending its replacement cycle overall can still prioritize which units to replace first, rather than either replacing everything on the old schedule or freezing all replacement decisions uniformly.
