Tariffs on Cars & Auto Parts: Complete 2026 Guide

The US automotive sector faces among the most complex tariff structures of any industry in 2026. Passenger vehicles and auto parts are subject to Section 232 national security tariffs (25%). Chinese EVs face Section 301 at 100%. Qualifying auto parts carry no Section 232 add-on under USMCA (heading 9903.94.06), but a USMCA claim does not remove the duty on passenger vehicles: a claimant still pays it on full customs value. The interaction of these three authorities — with different rates, different qualifying criteria, and different legal permanence — creates a multi-layer compliance challenge for automakers, dealers, and parts importers. For US consumers, the practical effect is higher vehicle prices. For manufacturers with integrated North American supply chains, USMCA provides a tariff lifeline. For importers of Chinese automotive goods, 100% tariffs on EVs and roughly 50% on most other categories (25% Section 232 plus 25% Section 301) have substantially closed the US market. This guide provides current rates, USMCA qualification requirements for automotive goods, and the cost impact across the supply chain from OEM to dealer.

Section 232 tariffs on passenger vehicles and auto parts took effect April 3, 2025, at 25%. That rate still applies to auto parts from every origin and to passenger vehicles from most origins. Japan, the EU member states, South Korea and the United Kingdom each have their own heading for passenger vehicles, and the total they pay is lower. What a USMCA claim removes is covered in the USMCA section below. Partner ceilings on passenger vehicles: Japan pays a total of 15%, with the MFN rate counted inside it. At a 2.5% MFN rate, the Section 232 portion is 12.5%. A German car pays the same total, and so does a car from any other EU member state. South Korea's total is 15% whether or not the entry claims the Korea-U.S. free trade agreement rate. Claiming it changes how the total splits between the column 1 duty and Section 232, not the total itself. The United Kingdom pays the MFN rate plus 7.5% under Section 232, a total of 10%, but only within its annual tariff-rate quota; vehicles entered above the quota pay the full 25%. We cannot tell whether a given shipment falls inside the quota, so 10% is the in-quota figure. Taiwan and every other origin pay the full 25% Section 232 rate on passenger vehicles. Coverage: passenger vehicles (HTS 8703 — cars, SUVs, minivans); light trucks (HTS 8704 — pickup trucks under 5 tonnes); major auto parts (HTS 8407-8409, 8706-8708) including engines, transmissions, drivetrains, body panels, and most OEM components. Rate: 25% ad valorem where no partner ceiling applies. On a $40,000 German luxury vehicle the Section 232 duty is $5,000, against $10,000 at the full 25%. On a $25,000 Japanese sedan it is $3,125, against $6,250. These amounts still represent cost pressure that manufacturers can either absorb (reducing margin), pass through (raising prices), or mitigate through North American production. USMCA and the S232 automotive tariff: qualifying auto parts from Canada and Mexico carry no Section 232 add-on (heading 9903.94.06). Passenger vehicles and trucks get no such exception: a USMCA claimant pays the 25% Section 232 duty on full customs value, on top of the USMCA rate (U.S. notes 33(a) and 38(a)). No other country is exempt from S232 automotive tariffs, though Japan, the EU member states, South Korea and the United Kingdom pay a lower total on passenger vehicles under the partner ceilings described above. Impact on vehicle prices: industry analysis estimates S232 has added $1,500–5,000 to the average sticker price of non-USMCA-qualifying vehicles. For Japan and the EU member states the Section 232 portion is 12.5% rather than 25%, so the duty on those vehicles is half of what an origin without a partner ceiling pays. Dealers have largely passed the cost to consumers.

Electric vehicles from China face 100% Section 301 tariff under the 2024 statutory review — effectively closing the US market to direct Chinese EV imports. This rate applies to Chinese-origin EVs regardless of where they are nominally marketed or distributed. The 100% rate makes Chinese EVs commercially unviable for US retail. A BYD Seal that costs $22,000 in China would face $22,000 in Section 301 duties alone before freight, MPF, or dealer markup — resulting in a US retail price of approximately $60,000+ for a vehicle that competes with mid-range Teslas at $40,000. The practical effect has been a near-complete absence of Chinese-brand EVs in the US market. BYD, Nio, and other Chinese manufacturers have focused on European, Southeast Asian, and South American markets where tariff barriers are lower. The 100% rate also affects Chinese-manufactured vehicles from non-Chinese brands. A vehicle with Chinese origin (manufactured in China, meeting Chinese content thresholds) faces 100% even if it carries a non-Chinese brand. This has complicated supply chain decisions for brands like Volvo (Chinese-owned) that manufacture in China for global markets. Section 301 stacks with MFN and with Section 232 (the applicable middle-tier authority for autos), but not with the forced-labor Section 301 backfill — autos are S232-covered and excluded from that backfill, the same exclusion Section 122 used to have. Chinese EVs face MFN + S232 (25%, the middle tier for autos) + China's own S301 (100%) — a combination dominated by the 100% S301 term.

A USMCA claim is the primary strategy for major automakers to maintain competitive pricing in the US market, but it does not remove the Section 232 duty on finished vehicles: a claimant pays it on full customs value, on top of the USMCA rate. A vehicle that Commerce has approved under heading 9903.94.03 pays the duty only on its non-U.S. content, but approval is per vehicle and we don't model it. Qualifying auto parts carry no Section 232 add-on under heading 9903.94.06, with knock-down kits and parts compilations as the exception. Section 338 is separate: from September 15, 2026, Canadian passenger vehicles under HTSUS 8703.10.50 and 8703.21.01 also owe the 50% Section 338 duty, which a USMCA preference claim does not waive. The automotive rules of origin under USMCA are the most demanding in any US trade agreement: 75% regional value content (RVC) calculated for the vehicle as a whole. Of that North American content, a defined share must come from labor earning at least $16/hour (the labor value content provision). Additionally, 70% of the steel and aluminum in the covered vehicle must be North American origin. Calculating 75% RVC: the vehicle's total cost includes all inputs at their actual cost. North American inputs count toward the 75% threshold. Chinese-origin components, European components, and other non-North American inputs count against it. A vehicle with $30,000 in total cost where $22,500+ (75%) is North American-sourced qualifies. Major OEMs (Ford, GM, Stellantis, Toyota NA, Honda NA) have spent billions restructuring supply chains to achieve USMCA qualification. Vehicles produced in US, Canadian, and Mexican plants generally qualify, but each model requires individual certification against the rules of origin. Vehicles from European and Japanese automakers produced in North American plants (BMW Spartanburg, Toyota Georgetown, Hyundai Montgomery) may also qualify — the certification is by vehicle model, not by brand nationality.

The Section 232 tariff on non-qualifying vehicles (25% at the full rate, lower for Japan, the EU member states, South Korea and the United Kingdom within its quota) has restructured the US new vehicle market in ways not seen since the Voluntary Export Restraints of the 1980s. For dealers selling imported vehicles: the tariff has squeezed allocations and raised wholesale costs. European luxury brands — Porsche, BMW imports, Mercedes imports — have seen substantial price increases. Some models produced in Europe have been discontinued for the US market; production has shifted to North American facilities for models where volume justifies it. For consumers: average new vehicle prices in Q1 2026 are $8,000–12,000 above Q4 2024 levels, with the tariff component accounting for approximately $4,000–6,000 of the increase. The remainder reflects reduced inventory and supply chain adjustments. For used vehicle markets: as new vehicle prices rise, demand for used vehicles increases, raising used car prices as well. Kelley Blue Book reported average used vehicle prices in February 2026 were 15% above November 2024 levels. For auto parts importers: the 25% S232 on OEM parts increases maintenance and repair costs for vehicles whose parts come from non-North American suppliers. Independent repair shops that source Japanese or European OEM parts face higher cost of goods, which they pass to consumers in repair bills.

Auto parts supply chains are among the most complex in manufacturing, with tier 1, 2, and 3 suppliers contributing components that ultimately reach vehicle assembly plants. The 25% S232 has triggered major reshoring and nearshoring decisions across the tier 1 supplier base. Mexico is the primary beneficiary of automotive supply chain shifts. Mexican auto parts manufacturing is deeply integrated into the North American supply chain, with significant tier 1 facilities from Continental, Bosch, Aptiv, Lear, and all major OEM suppliers. USMCA-qualifying Mexico parts reach US assembly plants at 0% duty, making Mexico the default destination for new investment in auto parts capacity. Japan and Germany: tier 1 suppliers in Japan (Toyota, Denso, Aisin networks) and Germany (ZF, Continental European plants, Bosch European) face 25% S232 on parts shipped to the US. For high-value parts (transmissions, advanced driver assistance systems), OEMs are co-investing with suppliers in US and Mexican manufacturing to reduce tariff exposure. China: Chinese auto parts face 25% S232 for standard parts plus potential China-punitive Section 301 (25%) for parts on S301 lists. The effective rate for many Chinese auto parts is 50% (S232 25% — S232-covered parts are excluded from both the now-lapsed Section 122 and the forced-labor Section 301 backfill, but they do face S232, and Chinese goods face their own punitive S301 stacked on top of S232 for applicable HTS codes). This has significantly reduced Chinese auto parts imports.
