Congress and federal trade regulators are waging a two-front campaign to cut Chinese battery makers out of the U.S. electric vehicle supply chain, combining legislative action with trade investigations that could reshape which EVs qualify for federal tax credits. The fight centers on whether Treasury Department rules adequately block companies linked to China from benefiting from Inflation Reduction Act incentives, and it has drawn bipartisan criticism from lawmakers who say the current framework contains exploitable gaps. If these efforts succeed, the short-term result could be higher battery costs and fewer vehicles eligible for the $7,500 clean vehicle credit, even as Washington pushes to accelerate EV adoption.
Congress Targets Treasury’s Battery Rules
The sharpest legislative tool aimed at Treasury’s approach is a disapproval resolution, H.J.Res.179, introduced during the 118th Congress to overturn the department’s final rule governing Foreign Entities of Concern, or FEOC, in the context of clean vehicle credits under Sections 25E and 30D of the tax code. The Congressional Review Act mechanism behind the resolution allows lawmakers to nullify executive branch regulations with simple majorities in both chambers and a presidential signature, after which agencies are barred from issuing a substantially similar rule without new statutory authorization. Applied to the EV tax rules, that would mean wiping out Treasury’s FEOC framework and forcing Congress to define the boundaries of Chinese involvement in the battery supply chain directly.
The FEOC rules determine which battery components and critical minerals can be sourced from companies connected to China, Russia, North Korea, or Iran without disqualifying a vehicle from the clean vehicle credit. A Government Accountability Office review of federal rulemaking explains how CRA disapproval can halt such regulations and limit agencies’ ability to revisit the same policy space, underscoring the stakes of Congress using this tool against Treasury’s EV guidance. Parallel analysis from the Congressional Research Service on the Section 30D restrictions describes how the final regulations define FEOC status, including enforcement mechanisms and scope distinctions that determine whether a given supplier relationship triggers disqualification. Critics in Congress argue these definitions are too narrow, allowing indirect sourcing arrangements and layered ownership structures to slip through.
Manchin and House Panels Call Rules a Gift to Beijing
Then-Senate Energy and Natural Resources Committee Chair Joe Manchin, D-W.Va., emerged as one of the most forceful opponents of Treasury’s implementation. In an official statement, Manchin accused the administration of effectively endorsing Chinese-made content through its final Section 30D rule, arguing that the FEOC provisions failed to erect meaningful barriers against Chinese-linked firms capturing EV supply chain benefits funded by U.S. taxpayers. He framed the issue as both a national security concern and a betrayal of the Inflation Reduction Act’s intent to onshore clean energy manufacturing.
The House advanced its own response. A committee report labeled the “End Chinese Dominance of Electric Vehicles in America Act of 2024,” published as H. Rept. 118-550, laid out detailed findings about what members described as loopholes in how IRA incentives interact with FEOC designations. The report argued that current definitions allow Chinese-affiliated battery suppliers to participate through subsidiaries, joint ventures, and complex ownership chains, while still leaving finished vehicles eligible for tax credits. To address that, the report attached legislative language that would tighten statutory definitions, expand disclosure requirements for automakers, and override Treasury’s more flexible regulatory choices with hard-edged rules written directly into law.
A separate Senate hearing captured under S.Hrg. 118-317 produced sworn testimony on the federal government’s role in building resilient EV supply chains. Witnesses from industry, labor, and national security circles described how Chinese-linked battery components and minerals continued to flow into vehicles that still qualified for tax credits, despite the FEOC restrictions. Senators used the hearing to press administration officials on enforcement, data transparency, and the risk that U.S. subsidies could entrench, rather than displace, Chinese dominance in upstream battery materials.
Trade Investigations Add a Second Front
While Congress works the legislative angle, the U.S. International Trade Commission has opened a parallel track focused on trade remedies. The USITC voted to continue antidumping and countervailing duty investigations into active anode material imported from China, finding a reasonable indication that domestic producers are materially injured or threatened with injury. Active anode material is a critical input in lithium-ion batteries, the chemistry that powers most EVs sold in the United States, so any duties imposed at the end of the investigation could ripple through the entire supply chain.
If the USITC and the Department of Commerce ultimately impose duties, the immediate effect would be to raise the cost of Chinese-sourced battery materials for manufacturers that still rely on them, regardless of whether their vehicles qualify for tax credits. That would add economic pressure on top of the FEOC regulatory restrictions, accelerating the search for alternative suppliers in allied countries or within the United States. For companies that have built business models around low-cost Chinese inputs, the combination of trade penalties and tax-credit disqualification could force rapid restructuring of procurement strategies.
This two-track approach, legislative nullification plus trade enforcement, is notable for its breadth. Congress is not simply asking Treasury to tweak definitions or adjust timelines. Lawmakers are simultaneously trying to erase the existing framework via the Congressional Review Act, enact new statutes with tighter restrictions, and use the trade remedy system to make Chinese battery inputs more expensive. Taken together, those steps would squeeze Chinese suppliers from multiple directions at once, while also signaling to automakers that Washington expects a decisive pivot away from China-linked content.
House Passes Bills Targeting Battery Supply Chains
The legislative push has continued alongside the regulatory and trade actions. On March 10, 2025, the U.S. House of Representatives passed two measures aimed at countering Chinese influence over battery supply chains, including the Foreign Adversarial Battery Dependence Act, as described in a Homeland Security Committee announcement. The bills would further restrict federal procurement from entities tied to foreign adversaries and direct additional scrutiny at companies sourcing batteries and critical minerals from China. Their prospects in the Senate remain uncertain, but House passage underscores the political momentum behind more aggressive supply chain decoupling.
Even as these measures advanced, some lawmakers warned that Chinese firms were already adapting. A Congressional Record entry from September 2025 highlighted the competitive threat posed by rapidly expanding Chinese EV manufacturers, with particular attention to BYD and other automakers that could leverage low-cost batteries to undercut U.S. and allied producers. The remarks argued that unless tax, trade, and industrial policies are aligned, Chinese companies might still find pathways into the U.S. market, whether through direct imports, assembly in third countries, or partnerships that fall just outside current FEOC definitions.
Implications for Automakers and Consumers
For automakers, the emerging policy landscape creates both risk and opportunity. Companies that moved early to localize battery production and diversify away from Chinese suppliers stand to gain a competitive edge if rivals lose access to tax credits or face higher input costs. Those that remain heavily dependent on Chinese materials could see specific models disqualified from the $7,500 clean vehicle credit, making them harder to sell in a price-sensitive market.
Consumers may feel the effects through higher sticker prices or reduced model availability, at least in the near term. Vehicles that no longer qualify for the credit will effectively become more expensive overnight, while manufacturers retool their supply chains to comply with tighter rules. Over the longer run, supporters of the crackdown argue that a more secure, domestically anchored battery ecosystem will stabilize prices and insulate the U.S. market from geopolitical shocks. Skeptics counter that moving too fast could slow EV adoption, undermining climate goals and leaving lower-income buyers behind.
What is clear is that EV policy is no longer confined to emissions standards and charging infrastructure. It now sits at the intersection of trade law, industrial strategy, and geopolitical rivalry. The outcome of the battles over FEOC rules, antidumping investigations, and new statutory limits on Chinese participation will help determine not only which vehicles qualify for federal incentives, but also where the most valuable parts of the clean energy economy are located.
