Updated Since Our May Report

The fleet industry is navigating a whirlwind of changes as it faces an uncertain future shaped by recent tariff updates. Since May 22, 2025, a series of significant tariffs have rolled out, dramatically affecting the cost and availability of vehicles, parts, and services for commercial and government fleets alike.
Imagine a 25% tariff on passenger vehicles and light trucks that took effect on April 3, adding thousands of dollars to the price of imports! While U.S.-assembled vehicles enjoy some relief, many still face hefty surcharges. With rising tariffs on steel and aluminum, fleet managers are now grappling with unpredictable pricing and sourcing challenges.
As vehicle procurement costs soar, fleet leaders must rethink their strategies and adapt to this new landscape, because preparing for the future means staying one step ahead of the next tariff twist!
The Core Tariffs for Fleets in 2025
A 25% tariff on passenger vehicles, light trucks, and most automotive parts—including engines and electronics—came into effect on April 3, 2025. This rate applies broadly, whether the vehicle is fully assembled or just a key component crossing the U.S. border. Commercial vehicles and medium- to heavy-duty models are also affected.
For vehicles assembled in the U.S., there is partial relief: if 85% of the content is made in the U.S. or is USMCA (United States-Mexico-Canada Agreement) compliant, no effective tariff applies in the first year. The new “import adjustment offset” mechanism lets U.S. automakers reclaim up to 3.75% of MSRP in 2025–2026, and 2.5% in 2026–2027, but only for vehicles meeting the content rule. These credits shrink over time; by 2027, credits disappear. Most vehicles fall short of the threshold and face some level of surcharge.
Imported-assembled vehicles—regardless of country—are estimated to cost as much as $10,000 more per unit, while U.S.-assembled vehicles sourced with foreign parts see increases of more than $3,000 per unit. These costs hit all forms of fleet procurement, from direct purchases to managed service agreements.
Steel and aluminum tariffs rose to 25% for imports from China (stacking atop auto tariffs) and 50% for goods covered under Section 232 from select countries, notably the EU. Copper now faces a blanket 50% tariff from all countries. For Japan, the European Union, and South Korea, general tariffs are now 15%, with strategic exceptions for certain goods.
Reciprocal Tariffs, Enforcement, and Exemptions
The administration paused the planned reciprocal tariff hikes for 90 days starting April 2, but as of August 7, a new “reciprocal tariff framework” was launched, setting country- and product-specific duties. Specific low-value shipments (previously exempt under De 
Minimis for China/Hong Kong) lost their exemption. Furthermore, if customs finds goods are transshipped to evade tariffs, a steep 40% tariff is now imposed, with no mitigation options or penalties waived.
USMCA-compliant finished vehicles and auto parts remain protected from the highest tariffs, but qualifying is complex and requires strong documentation. Non-compliant Canadian goods are hit with 35%, Mexican goods with 25% (exceptions for energy, potash).
Impact on Fleet Operations and Costs
Fleet managers, asset teams, and purchasing leaders must grapple with:
- A sharp decline in U.S. import volumes, down 5–6% year-over-year, with higher prices and volatile availability for new vehicles, parts, and service contracts.
- Greater exposure to cost increases for maintenance, repairs, and upfitting as parts surge in price due to new tariffs on steel, aluminum, and copper.
- Fewer incentives from OEMs and increased pressure to reshore sourcing, which is still constrained by supply chain realities.
- Expiration of USMCA auto exemptions, stricter documentation rules, and enhanced enforcement mean more administrative costs.
- The pause in some reciprocal tariffs provided a brief reprieve, but rates have now reset at markedly higher levels for many suppliers as of August 7.
- For government and commercial fleets, cross-border procurement (especially for specialty vehicles or equipment) faces unpredictable pricing and lead-time challenges going into 2026.
Future Outlook: Strategic Choices and Compliance
Business leaders should reexamine:
- Sourcing contracts for vehicles and critical parts for compliance with USMCA and new tariff regimes.
- Total cost of ownership models, as fleet budgets will have to absorb initial sticker shock, ongoing maintenance costs, and potential future tariff surges.
- The need for agile asset management and planning given that tariffs are subject to frequent revision and immediate policy shifts.
OEMs, fleet managers, and government buyers need to act now to document supply chain origins, consider accelerated domestic purchasing, and adjust incentive programs. Proactive compliance reviews and expert trade consultation are vital to avoid unexpected penalties under strengthened customs enforcement.
The Bottom Line
Tariff volatility and higher costs are the new normal for fleets. Leaders must prepare for strategic sourcing shifts, tighten their compliance controls, and budget carefully for higher price tags on vehicles, service, and parts as tariffs ripple through the market for years to come.
