The 25% Tariff: What It Is and How It Works

On March 26, 2025, the Trump administration issued a proclamation imposing a 25% tariff on all imported automobiles and auto parts under Section 232, with vehicle tariffs effective April 3, 2025, and parts tariffs — covering engines, transmissions, electrical systems, powertrains, and ADAS sensors — kicking in on May 3, 2025. The policy remains fully in effect as of May 2026, with no broad repeal or suspension.

The scale of this policy is significant. Over 30% of all auto parts used in U.S. repair shops are imported, and roughly 40% of U.S. auto parts come from Mexico and Canada alone. The Yale Budget Lab estimates that motor vehicle prices have risen an average of 13.5% — equivalent to roughly $6,400 per new vehicle — as a direct result of tariffs.

Key exemptions and adjustments as of May 2026:

• USMCA-compliant parts from Canada and Mexico are exempt based on verified U.S. content percentage — but only if importers secure Commerce Department approval. Misrepresentation risks full retroactive 25% duties.
• Import adjustment offsets allow U.S. automakers assembling vehicles domestically to offset up to 2.5% of aggregate MSRP in parts tariffs from May 2026 through April 2027 (down from 3.75% in the prior year). These offsets phase out entirely after April 2027.
• Bilateral deals with the EU, Japan, and South Korea have reduced applicable tariffs to approximately 15% for those origins.

Despite these carve-outs, the financial pressure on repair shops, insurers, and consumers remains substantial — and growing.

How Tariffs Inflate Repair Costs and Raise Your Premium

The path from a 25% tariff on auto parts to a higher insurance premium follows a clear and direct chain of events. Understanding it helps explain why your renewal quote may be climbing even if you haven't filed a single claim.

The Repair Cost Cascade

Repair shops surveyed in 2025 reported repair estimates running 10% higher compared to pre-tariff levels, with parts prices rising frequently. A component that previously cost $50 can now cost $60 or more as tariffs are passed down the supply chain. In a survey of 500 U.S. repair shops, 38.6% reported operational impacts, with 40.7% adjusting their pricing — including 36.8% raising product prices directly. Larger shops with eight or more bays were hit hardest, at 73.7% reporting cost increases.

Higher per-claim repair costs translate directly to what insurers call claim severity — the average payout per claim. As severity rises, insurers' combined loss ratios worsen, and they file for rate increases with state regulators. The motor vehicle repair CPI has risen 6.1% year-over-year as of early 2026, compounding a 43.6% cumulative increase in repair costs since 2019.

Total Loss Thresholds Rising

Another pressure point: as repair costs surge, borderline repairable vehicles are increasingly being written off as total losses rather than fixed. When a car worth $18,000 faces a repair estimate inflated by tariffed parts, the math increasingly tips toward a total loss declaration — increasing total loss claim payouts and feeding higher premiums across the entire risk pool.

Supply Chain Disruptions Add Delay Costs

Parts delays are compounding the dollar impact. About 26% of repair shops reported supply chain disruptions including higher shipping costs, and some face extended wait times stretching from days into weeks. Longer repair periods mean extended rental car costs — a covered expense under most comprehensive and collision policies — adding yet another line item to insurer payouts.

The broader vehicle repair cost inflation environment has been building since 2019, but tariffs are acting as an accelerant on top of an already expensive landscape.

Which Vehicles and Drivers Are Most Affected

Not all cars — or drivers — are equally exposed to tariff-driven rate increases. Several factors determine your level of risk.

Most Vulnerable Vehicle Types

Automakers have absorbed significant tariff-related losses — with some individual models facing price increases of $2,000–$15,000+ depending on assembly origin and parts sourcing. Those costs don't stay with the manufacturers — they eventually flow through to vehicle prices, repair estimates, and your insurance premium.

Geographic Variations

Tariff impacts on insurance premiums aren't uniform across the country. States that already carry the highest average premiums — like Nevada, Florida, Louisiana, and New Jersey — are seeing the sharpest dollar-value increases, since a percentage-based rate hike hits harder when your base rate is already elevated.

Insurify projects that states like New York could see full-coverage premium increases of up to $911 annually, with total national full-coverage averages potentially reaching $2,759 by end of 2025 — effects that are now rolling through into mid-2026 renewals. Meanwhile, states with more domestic-brand vehicle concentrations may see softer impacts. Learn more about how car insurance rates vary by state and which regions face the steepest increases.

How Long Will Tariff-Driven Increases Last — And What You Can Do

The Rate Increase Timeline

Insurance rate increases don't happen instantly. There is typically a 12–18 month lag between when tariffs are implemented and when consumers feel the full impact at renewal. This delay exists because insurers must first observe changes in claim costs, accumulate enough loss data to justify rate filings, and then obtain state regulatory approval before adjusting premiums.

With parts tariffs effective May 2025, consumers renewing policies in mid-to-late 2026 are now entering the peak window for tariff-related rate adjustments. Most analysts characterize the impact as lasting 1–3+ years without policy changes, with peak pressure concentrated in 2026 renewal cycles. Insurify projects premiums could reach ~$2,527 by end-2026 (a 4–9% increase above baseline), while CareEdge had forecast a standalone 5% tariff-related rate increase in 2025 — the cumulative effects of which are compounding into 2026.

The good news: car insurance rates show signs of stabilizing in 2026 after significant increases from 2022–2024, meaning tariff-driven pressure may be partially offset by improved insurer loss ratios and increased market competition.

What Consumers Can Do Right Now

1. Shop your policy every 6–12 months. Rate filings vary significantly by insurer. Requesting quotes from multiple carriers with identical coverage parameters can save $200–$500 or more annually. Tools like Jerry, The Zebra, and Gabi can compare multiple insurers simultaneously. How premiums are calculated differs between insurers — shopping exploits that variation in your favor.

2. Stack every discount available. Low mileage, good student, loyalty, paperless billing (3–5% savings), and paid-in-full discounts all reduce your base premium before tariff-driven inflation even enters the equation. Maintaining continuous coverage for at least six months with the same company before shopping also qualifies for loyalty discounts. Knowing all the factors that affect your rates puts you in a stronger negotiating position.

3. Accept aftermarket parts on older vehicles. Standard policies may already allow lower-cost aftermarket alternatives to OEM parts. For older vehicles, accepting aftermarket alternatives is generally a practical trade-off. However, for newer vehicles with ADAS systems, OEM parts are often required for proper sensor calibration — consider an OEM parts endorsement to ensure factory-quality repairs on newer models.

4. Adjust your coverage on older vehicles. If your vehicle is 8+ years old and worth less than $8,000, dropping collision or comprehensive coverage may save more than the coverage is worth — especially as tariff-inflated repair costs make total loss declarations more common on older cars.

Frequently Asked Questions

Why are tariffs causing car insurance rates to go up?

Tariffs raise the cost of imported auto parts by 25%, which directly increases what repair shops charge for collision repairs. Higher repair bills mean larger insurance claim payouts — what insurers call increased "claim severity." As claims become more expensive to pay out, insurance companies file for rate increases with state regulators to maintain financially sustainable loss ratios. The result is higher premiums for all policyholders, even those who haven't filed a single claim.

Which cars are hit hardest by tariff-related insurance increases?

Fully imported vehicles from Japan, Germany, and South Korea face the greatest exposure since the entire vehicle and its replacement parts carry the 25% duty. Luxury brands like Audi, BMW, and Volvo are particularly vulnerable — Audi raised 2026 model prices by up to $4,100 and Volvo XC90 prices by approximately $3,200. Even U.S.-assembled vehicles like the Ford Bronco Sport or Mustang Mach-E are affected if they rely heavily on foreign-sourced components, which is the case for many popular models. Volkswagen and Hyundai, which source 80% and 65% of their U.S. vehicles from imports respectively, face especially high exposure.

How much will tariffs increase my car insurance premium?

Industry estimates vary based on tariff scope and state. Insurify projects tariffs could add approximately $324 per year to the national average full-coverage premium — roughly a 7% direct tariff impact, on top of baseline inflation. For a driver in a high-premium state like New York, the annual increase could reach $911. CareEdge forecasted a standalone 5% tariff-driven rate increase in 2025, with effects compounding through 2026 renewals. The full impact is expected to peak during mid-to-late 2026, given the typical 12–18 month lag between tariff implementation and rate adjustments.

Are aftermarket parts a good alternative to OEM parts when tariffs are making repairs expensive?

Aftermarket parts can reduce repair costs meaningfully, and most standard auto insurance policies already allow their use. For older vehicles, accepting aftermarket alternatives is generally a practical trade-off that keeps both repair bills and premiums more competitive. However, for newer vehicles — particularly those equipped with advanced driver assistance systems (ADAS) — OEM parts are often required for proper sensor calibration and safety system functionality. Drivers of newer or leased cars should review their policy's parts language carefully and consider adding an OEM parts endorsement.

How long will tariff-driven insurance rate increases last?

Most analysts project tariff effects to last 1–3+ years without major policy changes. The 12–18 month lag between tariff implementation (May 2025) and full consumer impact means rate pressure is expected through much of 2026 and potentially into 2027. Whether increases persist long-term depends largely on whether trade policy shifts — including expanded bilateral exemptions or domestic parts production growth — reduce the tariff burden on key parts-exporting countries. Insurers' improved financial position following better loss ratios in 2025 may limit the magnitude of increases, but a full reversal requires either policy changes or significant expansion of U.S.-based auto parts manufacturing.
