EV makers’ China exposure is real: in 2025, China accounted for more than 80% of global lithium-ion battery manufacturing capacity, and Chinese producers supplied nearly 75% of global electric-car battery deployment, according to the International Energy Agency (IEA). U.S. tariffs, incentives to localize production and separate connected-vehicle restrictions can make that dependence harder or costlier to manage. But the effects vary by vehicle, supplier, assembly location and destination market; the available figures do not establish a single added cost or loss for every automaker.
Why China matters to electric-vehicle supply chains
China’s importance is not limited to finished vehicles. Its scale spans battery cells, materials, manufacturing equipment and supplier networks. That concentration can give automakers access to established production and suppliers, but it also creates exposure to trade barriers and export controls.
The IEA’s 2026 Global EV Outlook says China represented over 80% of global lithium-ion battery manufacturing capacity in 2025. Chinese producers supplied nearly 75% of electric-car battery deployment that year. Capacity and deployment measure different things: the first describes where manufacturing capability is located; the second describes the batteries actually deployed in electric cars.
Moving production is not an instant fix. The IEA says it can take most battery facilities more than five years after operations begin to approach nominal output, and that less mature production ecosystems face additional ramp-up challenges. A new plant’s announced or nameplate capacity therefore does not by itself establish that it can immediately replace mature supply at comparable output.

Exposure is not the same for every carmaker
A company’s risk depends on where its cells and materials come from, who owns or operates the suppliers, where vehicles are assembled, and which markets those vehicles enter. A firm with a local plant may still depend on imported materials or components; a company with Chinese suppliers may face different consequences depending on product classification and destination.
The IEA also projects that, in its stated 2035 scenario, more than one in four electric cars sold in advanced economies—about 6 million vehicles—would be made in China. That is a scenario projection, not a certainty about future sales or a claim that all those vehicles will be sold in the United States.
How U.S. tariffs add friction—and why the headline needs qualification
In March and April 2025, White House fact sheets described a 25% tariff framework for automobiles and auto parts, along with an offset for qualifying parts used in vehicles assembled in the United States. Those are policy descriptions, not a universal rate that can be applied to every EV, imported component or automaker. The result depends on the product’s tariff classification, origin, assembly location and eligibility under the offset rules.
The White House described an offset equal to 3.75% of a manufacturer’s U.S. production MSRP for the first stated year and 2.5% for the second, for qualifying parts used in U.S.-assembled vehicles. These figures describe the stated offset schedule, not an automatic refund or a guaranteed net tariff rate on a particular vehicle. They should not be subtracted from 25% as though every part or manufacturer qualifies on identical terms.

The administration’s stated rationale includes supporting domestic production and employment. A White House 2025 fact sheet put U.S. automotive-parts manufacturing employment at approximately 553,300 jobs in 2024, down 286,000, or 34%, since 2000. That figure is the administration’s account of the sector; it does not isolate EV jobs or establish that tariffs caused the historical decline.
The policy can nevertheless add sourcing friction: automakers may need to reassess suppliers, product classifications, documentation and where vehicles are assembled. The available sources do not quantify how much those changes raise costs for a particular company or how much of any tariff a manufacturer might pass on to consumers.
Earlier China-specific tariffs are a separate policy
In May 2024, the U.S. Trade Representative (USTR) announced higher Section 301 tariff rates, including 100% for Chinese electric vehicles and 25% for lithium-ion EV batteries. This was a Biden-era action, not a Trump administration measure. USTR also listed a 25% rate for natural graphite in 2026. These rates concern specified Chinese-origin goods under that policy; they should not be conflated with the later 2025 automobile and parts framework.
In its 2024 review, USTR summarized economic analyses as generally finding small negative effects on U.S. aggregate economic welfare, positive impacts on production in the 10 sectors most directly affected, and minimal economy-wide effects on prices and employment. That is USTR’s summary of analyses of the tariffs reviewed, not a conclusion about every firm, every tariff or the 2025 auto measures.

Export controls create a different supply risk
Tariffs raise the cost of covered imports; export controls can affect whether certain materials or technology can be obtained at all, and under what licensing conditions. In April 2025, the White House said China had suspended exports of six heavy rare-earth metals and rare-earth magnets, describing them as important to automakers and other industries. That was the administration’s characterization of the disruption.
China’s Ministry of Commerce and General Administration of Customs issued Announcement No. 58 of 2025 on October 9, establishing controls on specified lithium batteries, battery-manufacturing equipment and technology, and artificial-graphite anode materials. These measures concern listed products and technologies, not every battery or every shipment from China.
In a November 1, 2025 account, the White House said China would suspend global implementation of the expansive controls announced October 9 and issue general export licenses for listed materials, including rare earths and graphite. The same account said the United States would suspend heightened reciprocal tariffs through November 10, 2026, while retaining a 10% reciprocal tariff. As of October 8, 2026, that stated suspension period had not yet reached its end date. This is the administration’s published account of the arrangement; it does not establish that all licensing requirements or supply risks disappeared.

This is a market-access and compliance issue, distinct from duties on imported cars or parts. The operative dates and detailed applicability depend on the rule text and the particular hardware, software, supplier relationship and vehicle. A Chinese battery supplier alone does not establish that a vehicle is covered by the connected-vehicle restrictions; the relevant issue is the specified connectivity technology and its nexus to a covered country.
Can automakers move battery production out of China?
They can diversify, but substituting a mature supply chain takes time. The IEA’s estimate that most facilities can take more than five years to approach nominal output makes clear why announcements of new capacity do not instantly remove exposure. New facilities also need supplier ecosystems and production capability that can support dependable output.
For a useful comparison between automakers, look beyond a headline claim of “local production.” The relevant questions include:
- Cells and materials: Where are battery cells, graphite, rare earths and other inputs produced, and which suppliers provide them?
- Actual output: Is a facility operating at mature, high-yield output, or is it still ramping up?
- Vehicle configuration: Where is the vehicle assembled, how are its parts classified, and what content qualifies under applicable tariff rules?
- Market destination: Which country’s tariffs, export controls and vehicle rules apply to the finished vehicle and its components?
- Connectivity: Do covered hardware or software systems have the China- or Russia-linked connections addressed by U.S. restrictions?
- Alternatives: Can the manufacturer serve other markets or shift production, and at what cost and ramp-up pace?
What “made it worse” means—and what the evidence does not show
The case behind the headline is a mechanism, not a measured company-by-company verdict. China’s scale leaves automakers exposed to concentrated suppliers and materials. Tariffs can raise costs or complicate sourcing for covered goods; localization incentives can require production and sourcing changes; export controls can create licensing uncertainty; and connected-vehicle rules add compliance obligations for specified technology.
Those pressures exist alongside an administration rationale centered on domestic manufacturing and national security, and alongside the November 2025 easing described by the White House. The sources do not quantify the net effect of Trump administration policies on individual automakers, EV prices or the industry as a whole. A defensible assessment has to be made vehicle by vehicle and supply chain by supply chain, rather than by applying one tariff rate or one China-dependence label to every maker.
