The 25% Tariff on Auto Parts: What It Is and Why It Matters

In March 2025, the Trump administration imposed a 25% tariff on imported automobiles and auto parts under Section 232 of the Trade Expansion Act of 1962. Tariffs on completed vehicles took effect on April 3, 2025, while tariffs on auto parts became fully active on May 3, 2025. As of March 2026, these tariffs remain firmly in place — and their financial ripple effects are now reaching drivers across the country in the form of higher repair bills and steeper insurance premiums.

The tariffs apply broadly to parts imported from most countries, including engines, transmissions, electrical systems, and advanced driver assistance system (ADAS) components. USMCA-compliant parts from Canada and Mexico receive partial reductions, but the vast majority of imported components are subject to the full 25% duty. According to J.P. Morgan, the combined vehicle and parts tariffs are projected to cost the industry $41 billion in the first year, rising to $52 billion by year three — costs that are inevitably being passed down the supply chain to repair shops, insurers, and ultimately, you.

How Tariffs Compound an Already Broken Repair Cost Chain

The tariff impact didn't land on a healthy baseline. Auto repair costs were already in crisis before the first tariff dollar was collected. According to the U.S. Bureau of Labor Statistics, car maintenance and repair costs rose 43.6% from January 2019 to January 2025 — a surge driven by pandemic-era supply chain disruptions, global semiconductor shortages, rising labor costs, and the proliferation of expensive vehicle technology.

Year-over-year inflation in repair costs tells the story clearly:

Now add a 25% tariff on the imported parts that repair shops depend on, and costs escalate further. Individual repairs involving tariffed parts are estimated to cost an additional $20–$50 per repair, and insurers are reporting meaningful increases in claim severity — the average dollar amount paid out per collision or comprehensive claim. Motor vehicle maintenance and repair recently contributed 4.9% year-over-year inflation to the transportation category, accounting for 2.1% of the total annual change in consumer prices.

This is why the car insurance tariff impact is so significant: it's not a standalone cost spike — it's a multiplier on top of years of compounding cost pressure.

Which Vehicles Are Most Affected by Auto Parts Tariffs?

Not all cars are equally exposed to tariff-driven repair cost increases. The impact is most pronounced on vehicles with a high percentage of foreign-sourced components — whether they are fully imported models or U.S.-assembled vehicles that rely on global supply chains for major parts.

Automakers with the highest projected tariff exposure through early 2026:

Volkswagen, with approximately 80% of its U.S. sales imported, and Hyundai, with around 65% of U.S. vehicles imported, face the greatest parts cost exposure. Japanese brands — Toyota, Honda, Nissan, Mazda, and Subaru — are also heavily exposed due to deep offshore manufacturing footprints.

If you drive an import or an EV with foreign-sourced battery components, your insurer's cost to repair your vehicle has likely risen substantially since 2025. This directly affects collision and comprehensive coverage pricing. Learn more about which vehicles cost the most to insure and whether your model falls into a high-cost repair tier.

The Delayed Premium Impact: What Consumers Are Seeing in 2026

The link between tariffs and insurance premiums is real — but it operates on a lag. When auto parts costs rise, insurers don't immediately reflect those increases in your premium. Rate changes require actuarial modeling, state regulatory filings, and approval processes that can take 12 to 18 months to complete after the underlying cost shift occurs.

Since the 25% auto parts tariff became active in May 2025, widespread premium increases driven by these tariffs are landing for consumers right now — in 2026. Here's what analysts projected and what's materializing:

• Insurify projected the national average full-coverage premium would increase 4%–7% by end of 2025 due to tariff effects, depending on severity
• University of South Carolina expert Robert Hartwig projected individual premium hikes of $35–$120 per vehicle, depending on the car and repair needs
• States including Maryland, Delaware, Rhode Island, and Michigan were projected to face increases of 12–15% by year-end 2025
• High-premium states like Nevada, Florida, and California face ongoing pressure from elevated parts and labor costs

The combination of rising auto repair costs and tariff-inflated claim severity is forcing insurers to recalibrate. Even drivers who haven't filed a single claim are being affected, because insurers price policies based on the full risk pool — and the cost of every claim in the pool has gone up.

For a broader view of where car insurance rates are heading in 2026, including state-by-state breakdowns and insurer-specific changes, it's worth reviewing the full rate landscape before your next renewal.

What You Can Do to Mitigate Rising Insurance Costs

Even as tariff pressures push repair costs and premiums higher, you have meaningful levers to control what you pay. Here are the most effective strategies for 2026:

1. Shop and Compare Quotes Aggressively

The single most impactful step is requesting quotes from 3–5 insurers with identical coverage parameters. Comparing apples-to-apples can save you 15–30% on your annual premium. The factors that affect your car insurance rate vary by insurer — one company may rate your vehicle model far more favorably than another.

2. Adjust Your Deductible

Raising your deductible from $200–$500 to $1,000 can cut your collision and comprehensive premium by 15–30%. This strategy works best if you have savings to cover the higher out-of-pocket cost in the event of a claim.

3. Right-Size Your Coverage

If you own an older vehicle outright, reconsider whether full coverage still makes financial sense. If your annual collision premium exceeds 10% of your car's actual cash value, it may be time to drop to liability-only.

4. Stack Available Discounts

Bundle your auto policy with home or renters insurance (typically 5–15% off), sign up for a telematics/usage-based program for safe driving credits, pay in full instead of monthly to avoid installment fees, and ask about low-mileage discounts if you work from home.

5. Consider OEM Parts Coverage Carefully

With tariffs driving up the cost of genuine factory parts, understanding your policy's OEM parts coverage options is more important than ever. Standard policies may use lower-cost aftermarket alternatives — which can vary in quality but may also reduce claim costs.

Frequently Asked Questions

How do auto tariffs affect car insurance premiums?

Tariffs on imported auto parts increase the cost for repair shops to source components like engines, sensors, and body panels. As repair costs rise, insurance companies pay out more on collision and comprehensive claims — a dynamic known as higher claim severity. Insurers then recalibrate their premium models to account for these elevated costs, ultimately passing the increase to policyholders at renewal. The process typically involves a 12–18 month lag between when tariffs take effect and when consumers see the impact in their premiums.

Which cars are most affected by the 25% auto parts tariff?

Fully imported vehicles from Japan, Germany, South Korea, and other countries are most directly affected, since their parts must clear the 25% duty. However, even U.S.-assembled vehicles are impacted if they rely on significant quantities of foreign-sourced components — particularly ADAS sensors, infotainment modules, EV batteries, and electronic control units. Brands such as Toyota, Volkswagen, Honda, Hyundai, and BMW face some of the highest tariff exposure based on their global supply chain profiles.

How much could my car insurance premium increase due to tariffs?

Analysts estimate that tariff-driven premium increases range from approximately $35 to $120 per vehicle annually, depending on the car model and claims history. Nationally, full-coverage premiums were projected to increase 4%–7% as a result of tariff effects. Certain states with already-high premiums — such as Nevada, Florida, California, and Michigan — are seeing the sharpest increases. The full impact of the May 2025 tariffs is still being absorbed by insurers in 2026.

Are there any exemptions to the auto parts tariffs?

Yes, partial exemptions exist. Auto parts that qualify as USMCA-compliant — meaning they meet North American content requirements under the U.S.-Mexico-Canada Agreement — receive reduced duties rather than the full 25%. Additionally, the global 10% tariff that went into effect in early 2026 explicitly exempts automobiles and auto parts that are already subject to the Section 232 duties. Vehicles over 25 years old also qualify for special treatment.

What's the best way to offset tariff-related insurance increases in 2026?

The most effective approach is to comparison shop with at least three to five insurers before your next renewal, as rate differences between carriers for the same driver and vehicle can be substantial. Beyond that, raising your deductible, dropping unnecessary coverage on older vehicles, bundling policies, and enrolling in a telematics discount program are all proven ways to reduce your premium. Understanding how claims affect your rates can also help you make smarter decisions about when to file versus when to pay out of pocket.
