How the U.S. Lost Its Voice Over Deep-Sea Critical Minerals

The Clarion-Clipperton Zone, a stretch of Pacific seabed between Hawaii and Mexico, holds more copper, cobalt, nickel, and manganese than every known deposit on land combined. The country that wrote the legal framework governing who can reach those metals has held zero votes at the table where the rules get made. For over three decades.

That absence is not an accident of paperwork. The 1994 decision by the United States to sign but never ratify the UN Convention on the Law of the Sea (UNCLOS) is an active strategic choice, and it compounds. Every year of non-participation is another year in which the governance rules for deep sea critical minerals are written without an American vote, while U.S. industrial and defence policy increasingly treats battery metal supply chains as a national security priority.

Here is what that governance gap actually means for the competitive landscape, and how to hold the risk clearly given genuine uncertainty about when, or whether, commercial seabed mining becomes real. This is a material risk question, not a settled one.

The floor of the Pacific holds more battery metals than every mine on Earth, and accessing them is a governance problem, not a geology one

Start with the scale, because it frames everything that follows. The Clarion-Clipperton Zone (CCZ) is carpeted with polymetallic nodules, potato-sized rocks estimated to contain more copper, cobalt, nickel, and manganese than all known land deposits put together. These are the exact metals that battery chemistry and defence manufacturing depend on.

The entire zone sits under the administration of the International Seabed Authority (ISA), a United Nations agency that carves the seabed into licensed concession areas. As of a January 2026 ISA Council document, 31 exploration contracts are in force across all deep-sea resource types: 19 for polymetallic nodules, 8 for polymetallic sulphides, and 4 for cobalt-rich ferromanganese crusts.

Of those, 17 cover polymetallic nodules in the CCZ specifically. Nineteen countries hold CCZ licenses, including Russia, Japan, France, Germany, South Korea, Cuba, and Tonga. The ISA has also fenced off nine protected areas inside the CCZ, closed to mining entirely.

The ISA exploration contracts registry confirms that 19 of the 31 active contracts cover polymetallic nodules, with 17 of those concentrated in the CCZ, making the zone the single most contested area in deep-sea resource governance.

Now the number that reframes the whole picture. As of 2026, the ISA has issued zero exploitation contracts anywhere. No production licenses. No finalised commercial rulebook.

The metals are there. The technical challenge of collecting them is being worked on. What is not there is permission, and permission is a political product.

From geology to governance: why the ISA is the actual competitive arena

The ISA is the body that issues contracts, will set the exploitation rules, and adjudicates disputes over seabed resources in international waters. It is, in effect, the landlord, the zoning board, and the courthouse for the deep ocean.

Membership, voting rights, and financial contribution levels determine how much structural influence a state carries over how those rules get written. That is the lever that matters most in the near term.

Here is the read you should take from this: the competition right now is not over who currently mines the CCZ, because nobody legally can. It is over who shapes the rules that will govern mining when it becomes possible. For anyone tracking battery metal supply chains, the critical variable is influence over an unwritten rulebook, not ownership of an exploration block.

China has not just joined the table, it holds the most seats and funds the room

Look at China’s ISA position one contract at a time and a pattern assembles itself. China Ocean Mineral Resources Research and Development Association (COMRA) holds a CCZ nodule contract of roughly 75,000 km2, in force since May 2001 and extended to May 2026. This is a programme that predates most rivals by more than a decade.

China Minmetals Corporation holds a second CCZ nodule block of about 72,745 km2, in force from May 2017 and valid to 2032, drawn from ISA reserved areas. Beijing Pioneer Hi-Tech Development Corporation holds a third, roughly 74,052 km2, in force since October 2019 and running through 2034.

That is three of the 17 CCZ nodule contracts, held by three state-linked entities. Then extend the frame outward. COMRA also holds a polymetallic sulphides contract on the Southwest Indian Ridge (2011) and a cobalt-rich crusts contract in the western Pacific (2014).

That totals five of the 31 ISA exploration contracts, the largest portfolio held by any single state. China is also the ISA’s largest financial contributor. Access and institutional funding are not two separate stories; they are two moves in one strategy.

China’s terrestrial mining strategy, which already gives Beijing dominant processing positions in cobalt and rare earths, is structurally complementary to its ISA portfolio: seabed access diversifies supply options rather than substituting for land-based control, compounding the concentration risk that supply-chain analysts track.

The operational picture advanced in 2025. According to CSIS analysis published in May 2025, China Minmetals received ISA approval to run a mining trial in the CCZ, while Beijing Pioneer planned test-collection of nodules in its western Pacific area. These are steps beyond paper contracts, toward operational readiness.

China’s operational seabed readiness extended further in 2025 and 2026 than contract portfolios alone suggest, with technology demonstrations and processing trials moving state-linked entities closer to the extraction-to-battery supply chain integration that Beijing’s industrial strategy has long targeted.

Then there is the data-gathering pattern. A CNN/Mongabay investigation from March 2026 tracked eight Chinese deep-sea vessels over five years and found they spent only 6% of their open-water time near ISA-designated license areas. Analysts read the other 94% as extensive surveying and system refinement outside formal blocks.

One geopolitical analysis characterised China’s position as holding “both operational access to the resource and structural leverage over the body that determines who gets access to it.”

Put the pieces together and the inference is hard to avoid. The largest contract portfolio, the largest financial contribution, pilot approvals, and a vessel pattern pointing to systematic surveying outside licensed areas describe a coordinated long game, not an opportunistic grab. For anyone modelling supply chain concentration risk, that matters, because a strategy built on institutional influence is resilient to any single contract expiring or being denied.

What it means to have no vote: the mechanics of U.S. exclusion from deep-sea governance

“The U.S. has not ratified UNCLOS” is a true sentence that hides its own consequences. The specific mechanics are where the disadvantage becomes concrete.

President Bill Clinton signed UNCLOS in 1994. The Senate has declined to ratify it ever since, through multiple attempts, the most recent in July 2019, with no ratification resolution reaching a floor vote since 2020. The stated blocking position, held by 22 Republican senators, is opposition to ceding any regulatory authority to a UN body.

The executive branch does treat certain UNCLOS provisions, particularly those on navigational rights, as reflecting customary international law already followed in practice. That interpretive stance does not extend to ISA membership, voting rights, or the authority to sponsor mining contracts.

Here is what U.S. absence forfeits in practical terms:

• Authority to sponsor U.S. companies for ISA exploration contracts directly
• A vote on the exploitation rules that will govern all future commercial mining
• Formal committee representation within the Authority
• Formal influence over which contracts get approved

That leaves U.S. firms dependent on foreign sponsoring states for any CCZ access, which introduces legal and geopolitical exposure into the supply chain from the outset.

Retired U.S. Navy Rear Admiral Jonathan White characterised the United States as “sidelined from a critical emerging resource competition,” warning in 2019 that continued non-participation could deepen dependence on China for critical materials. He noted that China’s terrestrial sources already supply the majority of rare earth elements used in U.S. military guidance systems, X-ray technology, and microwave applications.

The most consequential gap is not that U.S. companies cannot currently mine the CCZ, because no company can yet. It is that the United States has no say in how the exploitation rulebook gets written. What this tells you is that the rules governing future commercial access will reflect the preferences of parties that include China and exclude the United States, and that disadvantage compounds with every ISA deliberation that proceeds without an American vote.

The risk is real, but so is the uncertainty: what analysts actually disagree about

The case against panic is not a set of reassurances to be waved away. It is a genuinely weighty body of analysis, and holding the risk clearly means taking it seriously.

Start with what is contested. Independent analysts and the Congressional Research Service (CRS) stress that CCZ nodule mining is not commercially proven, that no exploitation rulebook exists, and that projecting supply-chain dependence on minerals nobody has yet extracted at scale carries its own analytical risk.

The two sides line up like this:

• The genuine-risk view: U.S. absence forfeits votes over exploitation rules and contract awards; U.S. firms depend on foreign sponsors; China integrates ISA access into national battery-metal industrial policy; CCZ metals are strategically critical.
• The overstated-or-manageable view: economic recoverability is unconfirmed; no exploitation code exists as of September 2026, so commercial mining is not imminent regardless of who holds contracts; Pacific Island states and NGOs are pushing moratoria that could delay exploitation for years; alternative supply-chain tools exist.

Environmental and regulatory barriers that could delay everything

The environmental objection is substantive. Craig Smith, an oceanographer at the University of Hawaii, has compared the ecological significance of the CCZ to that of the Amazon and likened seabed mining to strip mining in its destructiveness, warning that ecosystem recovery would take an extremely long time.

Scientists routinely discover previously unknown species during CCZ expeditions, meaning the ecosystem being disturbed is largely uncharacterised. Documented concerns include sediment plume disturbance, biodiversity loss, and impairment of the seabed’s carbon sequestration function.

Deep-sea biodiversity impacts documented in recent expeditions extend beyond the species-discovery headline: sediment plume modelling now suggests disturbance radii far larger than licensed concession boundaries, which is one reason environmental objections carry enough evidentiary weight to influence ISA council votes on exploitation timelines.

Pacific Island states are calling for precautionary pauses through regional bodies and ISA deliberations. China Minmetals’ and Beijing Pioneer’s 2025 pilot approvals are contingent on evolving rules, not evidence of a settled regulatory environment.

What alternative mechanisms can and cannot substitute for UNCLOS ratification

Several tools are available to U.S. firms and policymakers without ratification. Companies can pursue ISA contracts through foreign sponsors. Bilateral critical-minerals agreements with UNCLOS-party allies, domestic industrial policy, terrestrial mining, recycling, and frameworks like EU battery regulations all offer partial substitutes.

Be explicit about the limit. None of these replicates ISA voting rights, formal committee representation, or direct U.S. company sponsorship authority. The substitution is partial at best.

The honest reading is this: the governance gap is a real structural disadvantage that could become a decisive supply-chain constraint if CCZ exploitation matures, but the timeline and viability uncertainties mean it should be held as a long-duration exposure, not an immediate crisis. Calibrate it correctly. Neither dismiss U.S. non-participation as inconsequential nor treat it as a near-term emergency.

What the governance gap means for the decade ahead, and where the real decision point sits

The competitive picture is now clear enough to state plainly. China’s five-contract ISA portfolio, its status as the Authority’s largest funder, its 2025 pilot approvals, and its vessel data-gathering programme together constitute a durable first-mover position. COMRA’s 2001 contract predates most rival programmes by more than a decade, which is the measure of accumulated advantage.

U.S. absence has compounded across 30 years of ISA governance. No post-2020 Senate Foreign Relations Committee action has moved UNCLOS ratification toward a floor vote. The exploitation rulebook that does not yet exist will matter enormously when it is finalised, and it will be written without an American voice.

Ratification remains the only mechanism that would give U.S. companies direct ISA sponsorship and the government a formal vote in exploitation rulemaking. Alternative tools are useful but structurally incomplete.

UNCLOS legal challenges against commercial operators reveal a parallel dynamic: companies pursuing deep-sea mining through non-ISA pathways face treaty-based objections from competing states, a risk that U.S.-sponsored firms would be better positioned to navigate if the Senate ratified and granted them direct ISA standing.

The governance positioning taken now will determine the supply-chain options available in the 2030s and 2040s, when battery metal demand for cobalt, nickel, and manganese is projected to reach its peaks and terrestrial supply concentration in China-linked or politically unstable sources is already a documented concern.

Three variables will determine how consequential this becomes:

• Timing of the ISA exploitation rulebook’s finalisation
• Pace of CCZ commercial mining development
• Whether U.S. legislative action on UNCLOS re-emerges in the current Senate term

For supply-chain analysts and mining and energy investors, read the CCZ governance gap as a slow-building structural risk, not an acute one. It belongs in long-duration supply security frameworks, not as a single-event trigger. The debate over whether the U.S. should have ratified in the first place is settled history. The open question is whether the window to mitigate the consequences, through alternative mechanisms or eventual ratification, is still meaningfully open. For now it is, but it narrows with each ISA cycle that proceeds without an American seat.
