The Foreign Entity of Concern framework was built on a specific assumption: that the threat to the American battery supply chain is Chinese materials entering American vehicles. Keep the Chinese materials out, the assumption goes, and you protect the domestic industry. Build the wall high enough and the supply chain is secure. That assumption is wrong. Not because the wall is too short. Because China may not be trying to walk through the door.

The Battery Supply Chain Series that precedes this piece spent ten parts documenting the domestic solution to American battery dependency. The anode is in contaminated American soil. The cathode lithium is in oilfield brine. The cathode phosphate is in the Salton Sea. The electrolyte is in seafood shells. The materials for American energy independence are not in China. They are here, in waste streams that America has been paying to manage rather than asking what they contain.

That series ended with a call to build. This one begins with a warning about what happens if America doesn't — and about the specific mechanism by which the window could close before anyone notices it closing.

The mechanism is not a tariff war. It is not a trade negotiation. It is not a cyberattack or a military provocation. It is an environmental services company offering to remediate American Superfund sites for free.

FEOC is a wall. China may be building a road around it — through the EPA's remediation program.

The Strategic Logic

To understand the threat, you have to understand what China actually wants from the American battery supply chain — and what it doesn't want.

China does not need to sell batteries to American OEMs. The American EV market, while large in absolute terms, is retreating. Ford has scaled back its EV commitments. GM took a $6 billion write-down and retooled Fairfax Assembly for ICE production. The political environment for EV mandates has deteriorated significantly under the current administration. The American market, in 2026, is not the growth story it was in 2022.

The growth story is India. One and a half billion people. A two-wheeler and three-wheeler market already electrifying at scale. A passenger car market that will be the largest on earth within a decade. Chinese EV manufacturers — BYD, SAIC, Chery — are already penetrating aggressively. The battery supply chain that serves India doesn't need to comply with FEOC. It doesn't need to qualify for the 45X credit. It doesn't need American OEM approval. It needs lithium, iron, phosphate, graphite, and a manufacturing base — all of which China either controls or is actively acquiring.

The American domestic waste streams documented in the Battery Supply Chain Series represent feedstocks that could, if developed, give American battery producers a structural cost advantage. Lithium from produced water at near-zero feedstock cost. Phosphate from Salton Sea remediation that someone has to pay for anyway. Graphite from contaminated soil that is currently a federal liability. These are not marginal advantages. They are the kind of structural input cost reductions that determine which supply chain wins at scale.

China's strategic interest is not to sell into the American market. It is to ensure that the American domestic supply chain never achieves the input cost structure that would allow it to compete globally. The way to do that is not to block American production. It is to acquire the feedstocks before American producers build the infrastructure to use them.

The Mechanism — What It Actually Looks Like

The vehicle for feedstock acquisition is environmental services. This is not speculation. It is the logical extension of a pattern already visible in Chinese industrial strategy in Southeast Asia, Africa, and Latin America — offer to solve the environmental problem, capture the material stream, lock in the supply chain position.

Applied to the American domestic context, the playbook looks like this:

Operational Sequence — The Environmental Services Vector
Stage 1Entry
Incorporate domestically. A Delaware LLC with American-named executives and a board that passes cursory scrutiny. Chinese capital structured through multiple holding layers — Singapore, Cayman Islands, Luxembourg — to obscure beneficial ownership. The Corporate Transparency Act was supposed to close this loophole. Enforcement was suspended in early 2025.
Stage 2Positioning
Target remediation contracts. Offer below-market or zero-cost remediation services for Superfund sites, produced water treatment, Salton Sea lakebed stabilization, municipal spent filter disposal. The offer is credible because Chinese industrial operations have genuine technical capability in hydrometallurgical processing. The below-market pricing is sustainable because the recovered materials are the real revenue stream — not the remediation fee.
Stage 3Extraction
Recover the materials. Lithium from produced water. Graphite from contaminated soil via FJH or equivalent. Phosphate from Salton Sea sediment. The recovered materials are legal byproducts of the remediation operation. FEOC does not apply to materials recovered from American soil by an American-incorporated entity. The beneficial ownership problem is an enforcement problem, not a legal prohibition.
Stage 4Routing
Route through non-FEOC intermediaries. Processed materials move to a facility in Vietnam, Malaysia, or Morocco — jurisdictions that are not FEOC-designated. From there they enter the global battery supply chain. The destination is not American OEMs. It is the Indian market, the Southeast Asian market, the European market. FEOC never triggers because the materials never enter an American vehicle supply chain. America cleaned up its environmental disaster. China captured the strategic resource. The accounting looks like a win for both sides.
Stage 5Denial
The feedstock is gone. By the time American producers build the infrastructure to access these waste streams — the lithium extraction facilities, the phosphate recovery plants, the graphite processing operations — the highest-concentration sites have already been remediated. The material has been extracted. What remains is lower-grade feedstock at higher processing cost. The structural input cost advantage that American domestic production would have had is gone. Not blocked. Quietly consumed.

Why FEOC Doesn't Cover This

The Foreign Entity of Concern framework under the Inflation Reduction Act — as modified by the One Big Beautiful Bill Act — applies to battery components and critical minerals used in vehicles claiming the 30D consumer credit or produced by facilities claiming the 45X manufacturing credit. It requires that qualifying materials not be extracted, processed, or recycled by a FEOC, and that battery components not be manufactured or assembled by a FEOC.

The scenario described above does not trigger FEOC at any stage. The remediation company is American-incorporated. The materials are extracted from American soil by an American entity. The processing occurs outside FEOC-designated jurisdictions. The finished battery components never enter an American vehicle supply chain at all — they go to India. No 30D credit is claimed. No 45X credit is claimed. No FEOC disclosure is required.

The FEOC Coverage Map — What It Protects and What It Doesn't
What FEOC covers: Chinese materials in American vehicles claiming tax credits. Chinese-owned battery component manufacturers supplying American OEMs. Direct Chinese corporate involvement in qualifying supply chains.

What FEOC does not cover: Chinese-capitalized American-incorporated entities operating in the domestic remediation market. Materials extracted from American soil and routed to non-American battery supply chains. Beneficial ownership structures that obscure Chinese capital behind multiple holding layers. Remediation operations whose recovered materials are never intended for American vehicle supply chains.

The enforcement gap: The Corporate Transparency Act beneficial ownership registry — the mechanism that would make FEOC tracing possible for shell companies — had enforcement suspended by FinCEN in early 2025. The primary tool for identifying Chinese capital in American-incorporated entities is currently non-operational.

The India Variable

The India dimension deserves explicit treatment because it fundamentally changes the strategic calculus. If China's goal were to penetrate the American market, FEOC would be a meaningful obstacle. The American market is large enough and the tax credit incentives significant enough that Chinese companies would have strong motivation to find workarounds — and FEOC enforcement, even imperfect, would impose real costs on those workarounds.

But if China's goal is to serve the Indian market — and the Southeast Asian market, and the African market, and the Latin American market — FEOC is irrelevant. Those markets have no FEOC equivalent. They have no domestic content requirements. They have no beneficial ownership disclosure mandates. They are growing faster than the American market. They will require more batteries per year than the American market within a decade. And they are being entered right now by Chinese EV manufacturers and battery producers who are not waiting for American policy to catch up.

The feedstocks in American waste streams — if acquired by Chinese-backed entities and routed to the Indian supply chain — would give Chinese battery producers a structural cost advantage in the fastest-growing battery market on the planet. Not by competing with American producers for American customers. By ensuring that American producers never build the cost structure to compete globally at all.

This is not market competition. It is strategic resource positioning. The difference matters because FEOC is a market competition tool. It has no answer for strategic resource positioning that bypasses the market entirely.

China doesn't need to sell batteries to America. It needs to ensure that America can never sell them to anyone else.

The Compounding Problem — The Big Three Retreat

The American political environment for EV policy has deteriorated significantly since the IRA passed in 2022. The consumer tax credit was eliminated. The domestic content ramp-up schedule has been questioned. Ford and GM have scaled back EV commitments. The political coalition that supported aggressive domestic battery supply chain investment has weakened substantially.

This retreat creates a vacuum. The companies that would have the strongest economic interest in securing domestic battery feedstocks — American OEMs planning major EV production ramps — are pulling back from those plans. The lobbying pressure for strong FEOC enforcement, for beneficial ownership disclosure, for federal investment in domestic lithium and phosphate and graphite infrastructure, diminishes in proportion to the OEMs' EV commitments.

The result is a policy environment in which the specific vulnerabilities described in this piece receive less attention at exactly the moment they are most acute. Chinese-backed entities can move into the American remediation market with less scrutiny, less competitive pressure, and less political opposition than would have existed two years ago.

The retreat from EVs is not just a market decision. It is a national security decision being made by people who are thinking about quarterly earnings, not about who will control the battery supply chain that serves two billion people in Asia over the next thirty years.

What Actually Closes the Gap

FEOC reform is necessary but not sufficient. Extending FEOC beneficial ownership tracing to remediation operations, reinstating Corporate Transparency Act enforcement, and closing the non-American-market routing loophole would all reduce the vulnerability. None of them eliminate it.

The only thing that actually closes the gap is speed. If American entities — domestic companies, state-backed investment vehicles, federal loan programs — build the infrastructure to extract and process these materials before Chinese-backed entities acquire the contracts to remediate the sites, there is nothing left to take. You cannot capture a feedstock that is already in a domestic supply chain.

The Battery Supply Chain Series laid out exactly what that infrastructure looks like and what it costs. Project ATLiS at the Salton Sea. Element3 in the Permian Basin. A phosphate recovery feasibility study that has not been commissioned. A chitosan electrolyte research program that has not been funded. A FJH graphite commercialization partner that has not yet signed an agreement.

Every day those investments are not made is a day the window is open. Not to Chinese batteries entering American vehicles. To Chinese capital entering American remediation contracts and walking out with the feedstocks that were supposed to make American batteries possible.

The wall is real. It is just pointed in the wrong direction.
