A foreign entity of concern, or FEOC, is a federal designation that blocks companies with ties to hostile foreign governments from receiving U.S. taxpayer subsidies, tax credits, and research partnerships. The label runs through the Bipartisan Infrastructure Law, the CHIPS and Science Act, and the Inflation Reduction Act. For car buyers, it decides whether an electric vehicle qualifies for the $7,500 clean vehicle credit. For semiconductor manufacturers, it can mean full repayment of a federal grant if the company crosses the line during a 10-year compliance window.
Who Counts as a Foreign Entity of Concern
The statutory definition appears in nearly identical form at 42 U.S.C. § 18741(a)(5), enacted through the Bipartisan Infrastructure Law, and 15 U.S.C. § 4651(8), enacted through the CHIPS Act.1Office of the Law Revision Counsel. 42 USC 18741 – Critical Minerals Mining and Recycling Research Five categories of entities qualify:
- Any entity the Secretary of State has designated as a foreign terrorist organization.
- Any entity on the Treasury Department’s Specially Designated Nationals and Blocked Persons list.
- Any entity owned by, controlled by, or subject to the jurisdiction or direction of the government of a “covered nation” identified in federal defense procurement law.
- Any foreign entity that the Attorney General alleges was involved in activities resulting in a conviction under the Espionage Act, the Economic Espionage Act, the Arms Export Control Act, the Export Control Reform Act, or similar federal statutes.
- Any entity that the relevant cabinet secretary, consulting with the Secretary of Defense and the Director of National Intelligence, determines is engaged in conduct detrimental to U.S. national security or foreign policy.2Office of the Law Revision Counsel. 15 USC 4651 – Definitions
The third category, covering government ownership and control, drives most of the day-to-day compliance work. The others either overlap with sanctions programs already administered elsewhere or depend on case-by-case federal findings.
The Four Covered Nations
Both FEOC statutes point to the defense procurement code for the list of covered nations. Under 10 U.S.C. § 4872(f)(2), the four are China, Russia, North Korea, and Iran.3Legal Information Institute. 10 USC 4872 – Covered Nation An entity headquartered, incorporated, or organized under the laws of one of these four automatically triggers scrutiny. The law treats presence in these jurisdictions as evidence that the entity is subject to that government’s legal authority.
The list is fixed by statute. Adding or removing a country requires an act of Congress, not an executive order. In practice, this means companies with suppliers in any of these four nations must map their ownership chains carefully or risk losing federal incentives.
The 25 Percent Ownership and Control Test
A company headquartered outside the four covered nations can still be an FEOC if a covered-nation government holds enough influence over it. The Department of Energy’s final interpretive guidance sets the threshold at 25 percent, measured separately across three metrics: board seats, voting rights, and equity interest.4Federal Register. Interpretation of Foreign Entity of Concern Hitting 25 percent on any one is enough.
Indirect ownership counts. If a covered-nation government holds shares through intermediate companies, those interests get traced back and aggregated. When multiple entities connected to the same foreign government each hold smaller stakes in one company, the DOE guidance combines those stakes. A government cannot park 10 percent through three separate holding companies to stay under the bar on paper.
Coordinated action counts too. If a covered-nation government has a formal arrangement to act in concert with another party holding interests in the same target company, the combined stakes of all coordinating parties push toward the threshold.4Federal Register. Interpretation of Foreign Entity of Concern Joint ventures, layered subsidiaries, and cross-held equity all get pulled into this cumulative analysis.
Clean Vehicle Tax Credit Disqualification
The rule most consumers encounter is the Section 30D clean vehicle credit disqualification. Under 26 U.S.C. § 30D(d)(7), a vehicle loses eligibility in two situations, each with its own effective date:5Office of the Law Revision Counsel. 26 USC 30D – Clean Vehicle Credit
- Effective January 1, 2024: no battery component may have been manufactured or assembled by an FEOC.
- Effective January 1, 2025: no applicable critical mineral in the battery may have been extracted, processed, or recycled by an FEOC.6Federal Register. Clean Vehicle Credits Under Sections 25E and 30D; Transfer of Credits; Critical Minerals and Battery Components
The credit is worth up to $7,500, split into two $3,750 halves: one for meeting critical mineral requirements, one for meeting battery component requirements.5Office of the Law Revision Counsel. 26 USC 30D – Clean Vehicle Credit The FEOC rule is a hard disqualifier, not a partial reduction. One critical mineral processed by an FEOC kills eligibility for both halves. The list of qualifying vehicles has narrowed sharply as a result, since many battery supply chains still run through China.
Automakers carry the compliance load. They must trace every step from raw mineral extraction through final assembly and show that no FEOC touched the chain. Treasury’s final regulations let manufacturers rely on attestations from supply chain participants, but the attestations must provide reasonable assurance that the chain is FEOC-free.4Federal Register.

CHIPS Act Grant Clawbacks
Semiconductor companies accepting CHIPS Act subsidies operate under a different set of restrictions. Under 15 U.S.C. § 4652(a)(6), any recipient must agree not to engage in any significant transaction involving the expansion of semiconductor manufacturing capacity in a covered nation for 10 years after the award.7Federal Register. Preventing the Improper Use of CHIPS Act Funding Violating the guardrail triggers full clawback of the entire federal grant.
A separate provision at 15 U.S.C. § 4652(a)(5)(C) prohibits CHIPS recipients from knowingly engaging in joint research or technology licensing with an FEOC on technology raising national security concerns. The Secretary of Commerce identifies the relevant technologies and notifies the recipient before any violation can occur. This restriction also carries a full clawback penalty.7Federal Register. Preventing the Improper Use of CHIPS Act Funding
There is a narrow exception for existing facilities producing older-generation “legacy” semiconductors that predominantly serve the market of the covered nation where they operate. A chipmaker already running a legacy fab in China does not have to shut it down, but expanding that facility’s capacity in any material way during the 10-year window puts the entire U.S. award at risk.
The 2025 Expansion to Prohibited Foreign Entities
A July 2025 executive order directed the Treasury Department to implement “enhanced Foreign Entity of Concern restrictions” enacted through new legislation, with a 45-day implementation timeline following enactment.8The White House. Ending Market Distorting Subsidies for Unreliable, Foreign-Controlled Energy Sources The new law introduces “prohibited foreign entities,” a broader concept applied to certain energy tax credits including the Section 45X advanced manufacturing production credit. Taxpayers that are prohibited foreign entities lose access to 45X, and receiving “material assistance” from such entities can also disqualify a project.
For energy storage projects starting construction in 2026, at least 55 percent of manufactured products must come from entities that are not prohibited foreign entities. For power projects starting construction the same year, the threshold is 40 percent. Detailed IRS tables are expected in late 2026. These rules layer on top of the 30D restrictions, so businesses working across renewable energy and advanced manufacturing now face FEOC-adjacent compliance obligations from more than one direction.
What Compliance Looks Like
Companies seeking federal subsidies or tax credits must document that they do not meet any FEOC criteria. For the clean vehicle credit, that means organizational charts tracing every layer of ownership from parent company down through subsidiaries involved in battery production. Board member nationalities, government affiliations, and the full voting-control chain all need to be disclosed.
The DOE’s final guidance handles 30D due diligence through Treasury’s regulations, which permit manufacturers to collect compliance attestations from supply chain participants. Those attestations are the primary verification mechanism for the battery component and critical mineral chain. They function as living documents. An equity transfer, a change in board composition, or a shift in government affiliation at any tier can flip an entity’s FEOC status overnight.
CHIPS Act compliance is more direct. Funding agreements impose binding contractual obligations, and the 10-year guardrail period means recipients must keep compliance records for the full duration. Certificates of incorporation, shareholder agreements, and equity transfer records all need to be ready for federal review at any point during that window.
Penalties for Getting It Wrong
The consequences are deliberately severe. A CHIPS Act violation triggers full repayment of the federal award, not a prorated reduction based on how far into the 10-year period the violation occurred.7Federal Register. Preventing the Improper Use of CHIPS Act Funding For semiconductor investments running into the billions, the deterrent is enormous.
On the tax credit side, the consequence is loss of the credit. If the IRS finds an FEOC in a vehicle’s battery supply chain, the $7,500 credit is disallowed entirely. When the credit was transferred to the dealer at the point of sale, the manufacturer or dealer may face recapture or audit exposure.
False FEOC certifications can also draw False Claims Act liability under 31 U.S.C. § 3729. Under the implied certification theory, submitting a claim for federal payment while misrepresenting regulatory compliance can give rise to civil penalties if the misrepresentation was material to the government’s payment decision. The materiality standard is demanding, but because FEOC compliance is an explicit eligibility condition for both CHIPS grants and clean vehicle credits, a false attestation on this point sits squarely in the zone where the government would refuse payment if it knew the truth.
