Deep Seabed Hard Mineral Resources — Ocean Floor Mining Law

The Deep Seabed Hard Mineral Resources Act of 1980 established a U.S. licensing regime for American companies to explore and mine polymetallic nodules and other hard minerals from the international deep ocean floor, pending a permanent international framework. Deep-sea nodules — potato-sized rocks containing cobalt, nickel, manganese, and copper — have attracted renewed commercial interest as the EV battery transition creates surging demand for the same minerals they contain. The 2025 Trump administration push to license deep-seabed mining unilaterally, bypassing the International Seabed Authority, made this obscure law one of the most diplomatically contentious natural resource statutes in the current policy landscape.

Current Law (2026)

Legal Authority

• 30 U.S.C. § 1401 — Findings and policy: Congress declares deep seabed hard mineral resources potentially important to the U.S. economy and national security; asserts the right of U.S. citizens to conduct exploration and recovery activities pending an international agreement
• 30 U.S.C. § 1411 — Exploration licenses: NOAA may issue licenses to U.S. citizens to explore the deep seabed for hard mineral resources; sets application requirements and environmental standards
• 30 U.S.C. § 1412 — Recovery permits: NOAA may issue commercial recovery permits to licensed explorers; permits are contingent on satisfactory environmental impact assessment
• 30 U.S.C. § 1415 — Environmental protection: requires permit applicants to conduct comprehensive environmental baseline studies; prohibits recovery that causes "serious harm or damage" to the marine environment; NOAA may impose mitigation conditions
• 30 U.S.C. § 1442 — International obligations: requires NOAA to act consistent with relevant international agreements; attempts to align domestic licensing with ISA framework where possible
• 30 U.S.C. § 1461 — Penalties: establishes civil and criminal penalties for unlicensed deep seabed mining or violations of permit conditions; up to $75,000/day civil penalties

How It Works

Under the Act, U.S. citizens or companies incorporated in the U.S. may apply to NOAA for an exploration license covering a defined area of the international seabed. NOAA evaluates the application, conducts an environmental review, and issues a license authorizing geological and geophysical surveys, small-scale sample collection, and resource assessment. Licensees who complete successful exploration and wish to proceed to commercial recovery must apply for a separate recovery permit, which requires a full environmental impact assessment covering the proposed collection area, the sediment plume from collection equipment, potential impacts to benthic ecosystems, and mitigation measures. No commercial recovery permit has ever been issued under the Act.

The international dimension complicates everything. The UN Convention on the Law of the Sea (UNCLOS) established the International Seabed Authority to govern the "Area" — the seabed beyond national jurisdiction — and requires member states to conduct seabed mining only through ISA-approved contracts. The United States never ratified UNCLOS, creating a legal ambiguity: U.S. law authorizes domestic licensing, but most nations and the ISA regard ISA authority as binding on all states under customary international law. The most advanced U.S.-connected operator, The Metals Company (TMC), holds ISA exploration contracts through a Nauru-sponsored subsidiary and applied to the ISA for a commercial exploitation permit in 2024. The ISA was still developing its commercial mining code when TMC's application triggered the "two-year rule" requiring the ISA to proceed with consideration even if the code was not finalized.

Deep-sea nodule fields are among the least-disturbed ecosystems on Earth. Nodules grow at a rate of about a centimeter every million years and host unique assemblages of sponges, corals, and microbial communities. Collection equipment dragging across the seafloor generates sediment plumes that marine scientists warn could spread hundreds of miles and smother filter-feeding organisms across vast areas. Recovery timescales for disturbed nodule fields are measured in geological time. Environmental groups and a large coalition of marine scientists have called for a moratorium on commercial seabed mining until baseline science and monitoring standards are adequate — a position endorsed by France, Germany, Chile, and several Pacific Island nations.

Key Numbers / Thresholds

• Clarion-Clipperton Zone estimated to contain ~21 billion tons of polymetallic nodules
• CCZ nodules estimated to contain more cobalt than all known land-based reserves
• 30 U.S.C. Act covers the "Area" — seabed beyond national jurisdiction (roughly beyond 200 nautical miles from any country's coast)
• Nodule growth rate: approximately 1 centimeter per million years
• Up to $75,000/day civil penalty for unlicensed recovery or permit violations
• TMC applied to ISA for commercial exploitation permit in 2024
• No commercial deep-seabed mining has occurred anywhere in the world as of 2026
• ISA has issued 31 exploration contracts globally (in the CCZ and other areas)

How It Affects You

If you're an investor or company in the critical minerals or deep-sea mining space: The 2025 Trump executive order directing NOAA to fast-track domestic seabed mining licenses created a bifurcated regulatory environment — U.S. domestic licenses under the 1980 Act running parallel to the ISA's international framework. TMC (The Metals Company) is pursuing both tracks simultaneously. The domestic license pathway is faster but creates legal risk: if the U.S. proceeds unilaterally and allies formally invoke UNCLOS-based challenges, any commercial operations could face international trade pressure. Monitor the ISA Council's formal response and watch whether allied nations move from protest to sanctions. The economics are compelling — CCZ nodules contain cobalt, nickel, manganese, and copper at potentially lower extraction cost than land-based mining — but no commercial recovery has occurred anywhere in the world as of 2026.

If you're in EV battery manufacturing or critical mineral supply chain planning: Deep-seabed polymetallic nodules represent a hypothetical future supply of cobalt and nickel that could reduce dependence on DRC cobalt and Indonesian nickel — but "hypothetical" is the operative word. No commercial mining has occurred. Even optimistic timelines project commercial production no earlier than 2027-2028, and regulatory and environmental challenges could push that further. Use deep-seabed projections as optionality in long-range supply chain planning, not as near-term sourcing alternatives. The sediment plume data from 2024-2025 test collections documenting far-field dispersal strengthens the case that environmental permitting — even under the accelerated Trump NOAA framework — will take longer than industry projections.

If you're in ocean science, environmental policy, or Pacific Island governance: The nodule growth rate of approximately 1 centimeter per million years makes CCZ nodules effectively non-renewable. The ISA's 31 exploration contracts are in areas where the first disturbances in decades have now been made to ecosystems that took millions of years to develop. Environmental organizations arguing for a mining moratorium pending more robust baseline data have scientific backing from 2024-2025 plume studies. Pacific Island nations (particularly Nauru, Kiribati, Tuvalu, and others with EEZs adjacent to the CCZ) have significant sovereignty and environmental stakes — several have formally opposed commercial exploitation through the ISA.

Recent Developments

In 2025, the Trump administration issued an executive order directing NOAA to fast-track domestic licensing for seabed mining in international waters, framing deep-seabed nodules as a critical minerals supply-chain opportunity and an alternative to DRC cobalt mining. The order directed NOAA to issue licenses to qualified U.S. companies and to identify regulatory barriers to commercial recovery. The ISA Council condemned the action as a violation of international law and UNCLOS principles, and several U.S. allies — including the EU, France, and Pacific Island states — formally protested. Legal scholars debated whether the U.S. domestic licensing authority under the 1980 Act extends to authorizing activities that the broader international community regards as governed exclusively by the ISA framework.

TMC, the company most likely to pursue a U.S. domestic license, publicly welcomed the executive order while also pressing its ISA commercial exploitation application. The dual-track strategy reflects the company's effort to hedge against ISA delays or a formal moratorium. Several environmental impact studies published in 2024–2025 documented persistent sediment plumes from test collection vehicles in the CCZ extending far beyond the collection zone, strengthening the scientific case for caution. The Biden-era NOAA environmental review of TMC's prior license applications, which raised significant concerns about plume impacts and cumulative effects, remained in the regulatory record as the Trump administration moved to streamline the process.

Implementing Regulations

The NOAA regulations implementing the Deep Seabed Hard Mineral Resources Act live at two parallel Parts — 15 CFR Part 970 for exploration licenses and 15 CFR Part 971 for commercial recovery permits — reflecting the Act's two-stage framework: explore first, then mine.

15 CFR Part 970 — Deep Seabed Mining Regulations for Exploration Licenses (73 sections):

• § 970.102 — Nature of licenses: an exploration license authorizes the holder to explore a specific portion of the deep seabed for hard mineral resources (primarily polymetallic nodules and crusts); the license does not authorize commercial recovery — a separate commercial recovery permit under Part 971 is required for that stage
• § 970.103 — Prohibited activities: no U.S. citizen may conduct exploration or commercial recovery without authorization; the prohibition extends to sponsoring, financing, or directing unauthorized operations; also prohibits exploration that has the effect of "commercially recovering" mineral resources without a permit
• §§ 970.201–970.208 — Application requirements: applicants must demonstrate (1) financial resources sufficient to carry out the exploration program (§970.201), (2) technological capability to conduct the exploration activities (§970.202), (3) a viable exploration plan covering the projected activities, timeline, and geographic area (§970.203), (4) environmental and use conflict analysis including input for NOAA's environmental impact statement (§970.204), (5) vessel safety information (§970.205), and (6) proof of U.S. citizenship for the applicant entity (§970.206); antitrust information must be submitted for FTC and DOJ review (§970.207); a nonrefundable administrative fee is required (§970.208)
• §§ 970.400–970.408 — Certification: NOAA's eligibility determination before full issuance review; NOAA must find the applicant financially responsible, technologically capable, in compliance with previous license obligations, and in possession of an adequate exploration plan; applicants must show they have paid all required fees; NOAA may deny certification if requirements are unmet (§970.407)
• §§ 970.503–970.507 — Pre-issuance findings: before issuing a license, NOAA must affirmatively find that the proposed exploration (1) will not unreasonably interfere with freedom of the high seas (§970.503); (2) will not conflict with U.S. international obligations (§970.504); (3) will not create a breach of international peace (§970.505); (4) cannot reasonably be expected to cause significant adverse environmental effects (§970.506); and (5) will not pose an inordinate threat to safety of life and property at sea (§970.507)
• § 970.515 — Duration: each exploration license is issued for 10 years; renewable upon substantial compliance with the exploration plan; licenses include diligence requirements to ensure active exploration rather than license-holding for speculative purposes
• §§ 970.518–970.521 — License conditions: each license must contain environmental protection requirements (§970.518), resource conservation requirements preventing waste (§970.519), restrictions to avoid interference with other high-seas activities (§970.520), and safety-at-sea conditions developed in consultation with USCG (§970.521)

The Part 970 exploration license framework establishes the first stage of U.S. deep seabed mining authorization. NOAA issued the first U.S. exploration licenses to companies such as Ocean Mining Associates, Ocean Minerals Company, Kennecott, and Deep Ocean Mining Company in the early 1980s — each covering millions of square kilometers of the Clarion-Clipperton Zone, a region of the central Pacific between Hawaii and Mexico that contains the world's highest concentrations of polymetallic nodules. These licenses were subsequently renewed and transferred as company consortia were restructured, but no commercial recovery permits were ever issued because the economics of deep seabed mining never became competitive with land-based mining during the late 20th century. The Trump administration's January 2026 executive order on seabed mining reactivated regulatory activity at NOAA, and the NOAA Administrator has indicated that exploration licenses for areas outside existing Part 970 license areas may be issued for the first time in decades.

The NOAA commercial recovery permit regulations implementing the Deep Seabed Hard Mineral Resources Act live at 15 CFR Part 971 — Deep Seabed Mining Regulations for Commercial Recovery Permits. Key provisions:

• § 971.100 (Subpart A) — Purpose: NOAA is the designated federal authority to issue commercial recovery permits to qualified U.S. citizens for mining hard mineral resources from the deep seabed; the regulations implement the Act's licensing framework distinct from the ISA process
• Subpart B — Applications (15 sections): an application for a commercial recovery permit must include a detailed description of the proposed mining system and equipment, an environmental baseline study of the proposed mining area, the applicant's financial qualifications to undertake the operation, a resource development and recovery plan, and a safety-of-life-at-sea plan; NOAA reviews for technical and environmental adequacy before certifying the application complete
• Subpart C — Certification of Applications (4 sections): once an application is certified complete, NOAA publishes notice in the Federal Register to allow other interested parties to object or assert conflicting claims; NOAA coordinates with the ISA and with other nations whose nationals hold exploration licenses over the same area
• Subpart D — Issuance, Terms, and Conditions (31 sections — the most substantive subpart): permits include enforceable terms covering: environmental protection requirements (based on the environmental baseline study); financial assurance in the form of a performance bond or trust fund covering estimated reclamation costs; reporting and recordkeeping obligations throughout the recovery operation; access for NOAA observers aboard mining vessels at any time; restrictions on operations outside the permitted area; and the permittee's obligation to share resource assessment data with NOAA
• Subpart F — Environmental Effects (6 sections): permit holders must implement an ongoing environmental monitoring plan approved by NOAA; must report any significant adverse environmental effect discovered during operations within 24 hours; must prepare and submit a post-season environmental assessment documenting sediment disturbance, benthic community impacts, and plume behavior
• Subpart J — Enforcement (8 sections): NOAA may assess civil penalties of up to $25,000 per violation per day for violations of the Act or the permit conditions; each day of a continuing violation is a separate offense; NOAA may place observers on vessels; the Act authorizes forfeiture of vessels and mineral resources used in unauthorized operations; permit suspension or revocation is available for serious or repeated violations

The Part 971 regulations remained largely dormant since their 1989 promulgation (54 FR 525) because no commercial recovery permits were ever issued — NOAA issued only exploration licenses under the parallel Part 970 framework. The Trump administration's January 2026 executive order on seabed mining triggered the first significant amendments to Part 971 in decades (91 FR 2672, January 2026), streamlining the application review timeline and updating the financial assurance requirements to reflect current mineral valuations. Whether these amendments will enable the first actual commercial recovery permit remains legally contested — the U.S. mining licenses operate under domestic law that the international community regards as inconsistent with UNCLOS.
