1. Introduction: Magnesium as a Strategic Critical Mineral for U.S. National Security
Defining Critical Minerals and Their Importance to the Defense Industrial Base
The United States government formally recognizes certain nonfuel minerals as "critical" due to their essential nature and inherent supply chain vulnerabilities. As defined by a National Research Council report, a critical mineral is indispensable for various applications and faces considerable risks in its supply.1 This definition was further codified by Section 7002 of the Energy Act of 2020, which empowered the Secretary of the Interior, through the U.S. Geological Survey (USGS), to identify minerals essential to the economic and national security of the United States that also possess vulnerable supply chains. In February 2022, the USGS published a definitive list of 50 such critical minerals, prioritizing them for domestic resource assessment and research.1
This formalized framework for identifying and assessing critical minerals signifies a profound understanding within the U.S. government of the direct link between mineral supply and defense readiness. The explicit legislative definition and ongoing systematic assessment elevate the importance of materials like magnesium beyond mere commodities, establishing them as foundational elements of national security. This formalization provides the legal and policy basis for proactive government action to secure their supply, demonstrating a clear strategic imperative to address potential weaknesses in the defense industrial base. These critical minerals are, in essence, the foundational building blocks for the defense industrial base, integral to the production of "virtually every Defense Department system, from unmanned aerial systems and fighter jets to submarines".2
Overview of Global Magnesium Supply Dynamics and U.S. Vulnerabilities
The global magnesium market presents a significant and alarming vulnerability for the United States and its allies. A stark reality of the current supply landscape is that "Russia and China currently control 90% of the global primary magnesium supply," with a notable absence of any significant producers within NATO countries.3 This extreme concentration of production in non-allied nations creates a perilous dependency, leading to what industry leaders describe as a "dire shortage of non-China supply" and an explicit "national security emergency" for Western nations.3
The geopolitical implications of this supply concentration are profound. Recent disruptions, often attributed to "adversarial actions," have starkly underscored the urgent necessity to build robust capabilities and resilience within critical mineral supply chains.2 This situation transcends conventional economic competition; it directly concerns the potential weaponization of supply chains. In an environment of heightened geopolitical tension or conflict, the ability of adversarial nations to restrict or halt magnesium exports could cripple U.S. defense manufacturing, jeopardizing operational continuity and eroding technological advantage. This direct link between supply concentration and national security risk is the core problem the DoD is actively working to mitigate, explaining the urgency and the strategic investments in diversifying sources. The lack of alternative, secure sources presents a critical single point of failure that the U.S. government is determined to address.

3. The U.S. Department of Defense's Critical Minerals Strategy and Magnesium Supply
U.S. Policy Framework for Critical Minerals
The U.S. government has established a robust and increasingly proactive policy framework for critical minerals, largely driven by the Energy Act of 2020. This legislation directed the Secretary of the Interior, acting through the USGS, to identify critical minerals based on their essentiality to both economic and national security, coupled with their vulnerable supply chains.1 This framework includes rigorous quantitative evaluations of supply risk, which consider factors such as net import reliance, the concentration of production outside the U.S., and the willingness or ability of producing countries to maintain supply. These quantitative assessments are complemented by qualitative evaluations to identify single points of failure within supply chains.1
Beyond identification, the U.S. Department of Commerce (Bureau of Industry and Security, Office of Technology Evaluation), in coordination with the Defense Logistics Agency (DLA), actively conducts industrial base surveys and assessments of critical material supply chains. The primary objective of these assessments is to gain a comprehensive understanding of the health and competitiveness of suppliers and to identify specific issues and challenges facing the industry. This crucial intelligence then informs the development of targeted planning and acquisition strategies, ultimately ensuring the availability of essential materials to support critical defense missions and programs over the long term.10 The existence of this detailed policy and assessment apparatus underscores the U.S. government's recognition of critical minerals as a strategic national security concern, moving beyond reactive measures to proactive long-term planning.
DoD's Strategic Objectives for Securing Critical Mineral Supply Chains
The U.S. Department of Defense unequivocally views the securing of critical minerals as "vital to the defense industrial base".2 The DoD's overarching strategic objective is to "build capability and resilience in supply chains for critical minerals," a necessity that has been starkly underscored by "recent disruptions [due to] adversarial actions".2 These disruptions have highlighted the urgent need to mitigate reliance on potentially unstable or hostile foreign sources.
To achieve these objectives, the DoD employs a multi-faceted strategy:
- Increased Domestic Mining and Processing: A key focus of industrial-based policies is to enhance domestic capabilities in both mining and processing critical minerals. This approach directly aligns with the broader DoD objectives to secure critical supply chains by reducing foreign dependency.2
- Partnering with Allies: The DoD places significant emphasis on leveraging partnerships with close allies. This includes utilizing a network of 19 "security supply cooperation arrangements" that enable priority delivery for DoD contracts and subcontracts.2 A significant development in this regard is the classification of Australian companies as a 'domestic' source by the U.S. DoD, reflecting the enduring commitment to strengthen alliances and integrate trusted partners into the defense industrial base.11
- Strategic Stockpiling: Stockpiling critical minerals serves as another crucial DoD strategy. These stockpiles reduce risk from unanticipated demand spikes or supply chain disruptions, effectively acting as "shock absorbers" during unforeseen events.2
The DoD has demonstrated a strong commitment to these objectives through substantial investments. Since 2020, over $439 million has been awarded to establish domestic rare earth element supply chains.2 Furthermore, Defense Production Act (DPA) awards have been made to allied partners, such as Canada, for key materials including cobalt, graphite, and tungsten, illustrating a willingness to invest directly in allied critical mineral projects.2 These actions collectively demonstrate a comprehensive and aggressive approach to de-risk the supply chain for materials vital to national security.
Analysis of the Current Global Magnesium Supply Chain and U.S. Dependence on Adversarial Nations
The current global magnesium market presents a severe strategic vulnerability for the United States. The stark reality is that "Russia and China currently control 90% of the global primary magnesium supply," with a complete absence of any significant producers in NATO countries.3 This extreme concentration of production outside of the United States, particularly within nations identified as potential adversaries, creates a profound supply chain vulnerability. The lack of alternative, secure sources within allied nations presents a critical single point of failure and significant geopolitical risk, as the ability to weaponize this supply chain could have devastating consequences for U.S. defense readiness.1
In response to this critical dependency, the U.S. government has implemented powerful policy instruments designed to fundamentally reshape the global magnesium market. A clear example of this is the recent U.S. Presidential Action issued on April 2, 2025, which explicitly exempted "Magnesium, unwrought, containing 99.8 % by weight of magnesium" (HTSUS Item 81041100) from tariffs for allied nations.12 This exemption unequivocally confirms magnesium's designation as a critical mineral to the U.S., Canada, UK, Japan, and Australia, formalizing its strategic importance.12 Crucially, this same Presidential action imposed a significant 54% ad valorem duty on China-produced magnesium, thereby creating a substantial competitive advantage for non-adversarial sources against Chinese imports in the U.S. market.12 This action transcends traditional trade policy; it represents a strategic move to actively de-risk the supply chain by making non-adversarial sources significantly more competitive and incentivizing their growth. This directly aligns U.S. economic policy with its national security objectives, demonstrating a sophisticated approach to securing critical material supply by leveraging market forces.

Detailed Account of Latrobe Magnesium's Engagement with the U.S. Market and DoD
Latrobe Magnesium has undertaken deliberate and strategic steps to integrate itself into the U.S. market and engage directly with the Department of Defense, reflecting a strong mutual interest in securing critical magnesium supply.
A pivotal development occurred on April 8, 2025, when Latrobe Magnesium officially confirmed that its magnesium exports to the U.S. are not subject to tariffs.12 This exemption stems from a U.S. Presidential Action issued just days prior, on April 2, 2025. While this action imposed duties on other imports, it specifically exempted "Magnesium, unwrought, containing 99.8 % by weight of magnesium" (HTSUS Item 81041100).12 This exemption unequivocally confirms magnesium's designation as a critical mineral to the U.S., Canada, UK, Japan, and Australia, formalizing its strategic importance within allied supply chains.12 Crucially, this same Presidential action also imposed a significant 54% ad valorem duty on China-produced magnesium, thereby creating a substantial competitive advantage for LMG against Chinese imports in the U.S. market.12 This policy is not merely a trade measure; it is a clear and powerful instrument designed to fundamentally reshape the global magnesium market by actively de-risking the supply chain, making non-adversarial sources significantly more competitive and incentivizing their growth. This demonstrates a sophisticated approach to securing critical material supply by aligning economic policy with national security objectives.
LMG's stated long-term intention is to sell all of its planned production of refined magnesium metal under long-term contracts to U.S.-based distributors.11 This commercial strategy directly supports the U.S. objective of diversifying its magnesium sources.
Direct engagement with the DoD is also well underway. LMG has completed its registration with the Defence Industrial Base Consortium (DIBC) in the United States, a crucial step for formal integration into the U.S. defense industrial base.11 A significant policy development facilitating this is the U.S. DoD's classification of Australian companies as a 'domestic' source, a classification that aligns with the Critical Minerals Compact enacted between the two countries in 2023.11 This reclassification streamlines procurement and collaboration processes. LMG is actively compiling a 'Whitepaper' tailored to DoD requirements, slated for submission in the upcoming quarter. The purpose of this whitepaper is to determine LMG's eligibility to pursue DoD grant and financing opportunities, signaling a proactive pursuit of strategic partnerships.11 Concrete validation of LMG's relevance to U.S. defense supply chain needs comes from "Recent enquiries from US Defence Department seeking MgO".12 This direct interest from the DoD in LMG's output, even at the magnesium oxide stage, provides tangible evidence of the U.S. defense establishment's demand for LMG's products.
The confluence of U.S. policy (tariff exemption, 'domestic' sourcing for Australia), direct DoD inquiries, and LMG's proactive engagement (DIBC registration, Whitepaper submission) demonstrates a powerful and developing strategic alignment. The U.S. government is actively creating favorable market conditions to support and integrate LMG, while LMG is strategically positioning itself as a vital solution to a critical U.S. national security vulnerability. This reciprocal benefit model strongly suggests a high likelihood of future DoD support and deeper integration into the U.S. defense supply chain, moving beyond mere commercial transactions to a strategic partnership.
