Analysis date 2026-09-17
If China continues and expands export controls on critical minerals such as gallium and germanium, as well as rare earths, as part of its countermeasures to U.S. tariffs, how will global semiconductor and clean energy supply chains be affected?
The 'continue and expand' premise has partly materialized as of the verification point and now operates on three tracks: the structural licensing regime and extraterritorial 0.1% rule are in force; the gallium, germanium, antimony and superhard-material ban against the United States is suspended until 2026-11-27; and the ban on 10 U.S. companies including MP Materials and USA Rare Earth is in force. 'Suspension as leverage' itself restrains foreign-company decision-making.
The transmission mechanism is real and already operating: China accounts for more than 85% of refined gallium, approximately 60%–80% of germanium and about 90% of heavy rare-earth mining; exports of yttrium, dysprosium and terbium fell approximately 50% versus the 12 months before controls; overseas dysprosium oxide and yttrium oxide have traded at price gaps ranging from multiples to more than 100 times versus China DDP; and second-order cases have emerged, including temporary shutdowns by an airline because of yttrium shortages and production cuts by automakers because of magnet shortages.
The impact is uneven and its geographic distribution diverges from the 'targeted at the United States' narrative: Japan received approximately 4% of its pre-control dysprosium imports from China and Germany approximately 0%, meaning allies have been hit harder than the United States. Meanwhile, domestic Chinese rare-earth prices weakened in September 2026, indicating that the market is pricing 'precision controls' rather than a 'total cutoff'.
Price elasticity is extreme but the aggregate macroeconomic impact is limited: USGS once estimated that a comprehensive gallium and germanium embargo would reduce U.S. economic output by approximately $3.4 billion, negligible relative to GDP. The shock is concentrated in the gross margins of specific industries, delivery delays and working-capital usage.
Key confounding variables must be excluded: the spillover from the Middle East conflict in March 2026 (QatarEnergy's suspension of aluminum and helium operations and disruption to passage through the Strait of Hormuz) also lifted gallium prices. Attributing the move solely to Chinese controls would overstate their effect.
Core causal chains
Macro impact
Export licensing and the extraterritorial 0.1% content rule cause cross-border flows of controlled items to be determined by administrative approval rather than price clearing. Trade volumes are compressed administratively, and companies must establish independent compliance systems
Supporting evidence
- Gallium and germanium export licensing implemented from 2023-08 and incorporated into the unified dual-use items list in 2024-12
- Five rare-earth categories—holmium, erbium, thulium, europium and ytterbium—added in 2025-10, together with the extraterritorial 0.1% content rule
- Yttrium, dysprosium and terbium exports fell approximately 50% versus the 12 months before controls
Counter-evidence
- The gallium, germanium, antimony and superhard-material ban against the United States has been suspended from 2025-11-09 through 2026-11-27
- China exported 6,000 kg of gallium to Japan in 2026-05, the first resumption in four months
Domestic-overseas price gaps become structural and downstream BOM costs rise; availability rather than price becomes the primary constraint, shifting procurement from JIT to safety stocks and increasing working-capital usage
Supporting evidence
- Benchmark Q2 2026: European CIF dysprosium oxide was 6.8 times China DDP, while North American CIF yttrium oxide was 188 times China DDP
- Platts' first assessment on 2026-03-31 showed a North American 'security-of-supply premium'
- Manufacturers abandoned JIT and built raw-material inventories (DigiTimes 2026-03)
Counter-evidence
- China's domestic rare-earth market was quiet in mid-September 2026, with downstream buyers waiting and terbium oxide and praseodymium-neodymium oxide weakening, indicating no global hard shortage
- China's Q2 praseodymium-neodymium index fell 5%
Critical minerals represent a small but indispensable share of input costs. Their price elasticity is extreme, but their direct contribution to end-consumer CPI is weak; transmission appears through margin compression and delivery delays in specific industries
Supporting evidence
- Gallium has a limited share of GaN-device BOMs but affects yields
- USGS once estimated that a comprehensive gallium and germanium embargo would reduce U.S. economic output by approximately $3.4 billion
Counter-evidence
- The USGS model is a static assumption, not a forecast
- The March 2026 Middle East conflict spillover—including QatarEnergy's suspension of aluminum and helium operations and disruption to Hormuz passage—also lifted gallium prices; the confounding variable must be excluded
Stronger export controls institutionalize the geopolitical nature of resources; concentration in refining rises rather than falls, and alternative capacity cannot reach scale in the short term
Supporting evidence
- IEA Global Critical Minerals Outlook 2025: China is the highest-output country for 19 of 20 energy-related minerals, with an average share of approximately 70% of global refining
- The top-three refining-country share rose from 82% in 2020 to 86% in 2024
- U.S. magnet capacity is expected to reach approximately 20,000 tonnes per year by 2030, around 7% of China's approximately 300,000 tonnes per year
Counter-evidence
- The G7 alternative-supply-chain initiative, U.S. DFC lending capacity expanded to $205 billion, and DoD's $400 million equity investment plus a $110/kg NdPr 10-year price floor
- Rio Tinto's Quebec gallium project is scheduled to start in 2027 (4-tonne demonstration/40-tonne potential); Nyrstar Hobart approximately 5 years
The extraterritorial 0.1% content rule requires licenses for overseas products containing Chinese rare earths above the threshold, externalizing compliance costs to almost all rare-earth-containing electronic and mechanical products; transshipment may also partially circumvent controls
Supporting evidence
- Extraterritorial 0.1% content rule introduced in 2025-10
- German imports of gallium from the United States surged 1,111% in 2022–24
Counter-evidence
- The rule's actual enforcement and distribution of benefits and costs are uncertain, making it difficult for markets to price
- It may trigger WTO disputes or reciprocal measures
Supply-chain impact
Gallium and germanium are by-products of aluminum and lead-zinc smelting. Higher prices benefit by-product returns, but export licensing restricts shipments and suppresses domestic Chinese prices
Supporting evidence
- Gallium is a by-product of bauxite-to-alumina refining; germanium is a by-product of lead-zinc smelting and coal ash
- China accounts for more than 85% of refined gallium and approximately 68% of germanium output
Counter-evidence
- Domestic Chinese rare-earth and some metal prices weakened in September 2026; the net effect of lower volumes and higher prices depends on the export share
- Higher prices make previously uneconomic recycling viable, suppressing the scarcity premium over the long term
Export licensing constrains delivery and overseas customer retention; overseas spreads widen but domestic prices remain weak, pressuring domestic-sales margins. The net effect depends on export share and the pace of licensing approvals
Supporting evidence
- Export volumes halved while overseas Dy/Tb prices rose 4–5 times and Y approximately 140 times
- SMM on 2026-09-16/17 showed a quiet domestic rare-earth market and downstream buyers waiting
Counter-evidence
- Suspension of the U.S. ban and resumption of gallium exports to Japan show that controls are reversible
- A split structure of domestic oversupply and restricted exports may persist
Higher gallium costs and constrained availability raise GaN/GaAs wafer costs and create delivery risks
Supporting evidence
- Gallium prices rose approximately ninefold in three years (Nikkei 2026-08 reference: approximately $3,050/kg)
- The 2025 shortfall was approximately 140 tonnes and is expected to exceed 270 tonnes in 2026 (Chinese industry research, not official)
Counter-evidence
- Price definitions differ materially ($2,100/$2,269/$3,050 per kg); a single Argus Western Market Indicator should be used
- The Middle East conflict also disrupted aluminum supplies and gallium by-product production, so attribution requires caution
RF front-end products based on GaAs/GaN have almost no substitute and are price-insensitive but availability-sensitive; power GaN has partial substitution by SiC in high-voltage applications, creating a differentiated substitution path
Supporting evidence
- GaN and SiC can substitute in some high-voltage applications
- GaN's short-term advantage remains intact in high-frequency and medium-/low-voltage applications
Counter-evidence
- Substitution is limited to specific applications, and SiC is a technology competitor rather than a direct beneficiary of gallium controls; conceptual links are easily misassigned
GeO₂ is almost functionally irreplaceable as a single-mode fiber-core dopant. Constrained germanium supply and expanding data-interconnect demand, combined with an 18–24-month preform capacity-expansion lead time, prolong delivery risks
Supporting evidence
- Approximately 35% of germanium is used in fiber optics, 30% in infrared applications and 15% in electronics
- Preform capacity expansion has an 18–24-month lead time
- AI data-center interconnection expansion is lifting structural demand
Counter-evidence
- The unusually wide range of germanium-price estimates ($2,500–3,500 versus approximately $8,597/kg) makes the shortfall difficult to quantify reliably
- Improved recycling economics partially alleviate supply
Germanium is used in infrared systems and satellites, while yttrium is used in turbine-blade thermal-barrier coatings. Demand is inelastic and amplified by geopolitical conflict; temporary airline shutdowns have already been reported
Supporting evidence
- Reuters reported in 2026-02 that some U.S. aviation companies temporarily halted production because of yttrium shortages
- The White House reportedly intervened to secure licenses for a dual-use company, which was said to be losing hundreds of millions of dollars in revenue per month
Counter-evidence
- The United States obtained some supplies through licensing approvals and White House intervention; the damage appears episodic rather than a generalized shutdown
- The second-order shutdown sample is insufficient to quantify the mechanism's prevalence
NdFeB magnet costs rose 1.5–3 times and supply was constrained, causing production cuts. Permanent-magnet direct-drive wind turbines face higher costs, with some designs shifting toward semi-direct-drive or electrically excited systems
Supporting evidence
- Magnet prices rose 1.5–3 times (Benchmark)
- Production cuts occurred after April 2025 because of rare-earth shortages
Counter-evidence
- Reduced-dysprosium use, grain-boundary diffusion, ferrite and rare-earth-free motor routes are advancing
- A demand slowdown or delay would reduce scarcity
MP Materials and USA Rare Earth were placed on China's control list, disrupting processing and technical cooperation; however, the DoD price floor and equity investment provide a profit floor. Reliance on external process validation during capacity expansion creates financing and delay risks
Supporting evidence
- The Ministry of Commerce announcement No. 23 of 2026 on 2026-06-22 placed MP Materials, USA Rare Earth and eight other U.S. companies on the control list
- DoD's $110/kg NdPr 10-year price floor and $400 million equity investment
- 10X Magnetics targets production in 2028 at approximately 10,000 tonnes per year
Counter-evidence
- The USAR Oklahoma magnet plant will not start until 2028
- MP's Mountain Pass produced 8,900 tonnes in 2025, approximately one-third of U.S. consumption under one estimate, or domestic production under another; its scale remains very small relative to China
Partial substitution of GaN in high-voltage power applications and improved recycling economics at higher prices create a second-order substitution beneficiary
Supporting evidence
- GaN and SiC can substitute in some high-voltage applications
- Higher prices make previously uneconomic recycling viable
Counter-evidence
- Global secondary recycling covers less than one-third of germanium demand
- The pace of substitution and technological convergence is highly uncertain; conceptual labels should not be extrapolated

- China accounts for 60%–80% of global germanium refining
Counter-evidence
- Germanium is a by-product and contributes relatively little to total company profit; the cycle of the main products may be more important
- Domestic germanium prices are suppressed by restricted exports
Aluminum Corporation of China
Gallium is a by-product of alumina refining, so higher overseas gallium prices increase by-product returns, but export licensing and the status of the U.S. ban determine shipments. The company's core electrolytic-aluminum and alumina cycles matter more

- The gallium, germanium, antimony and superhard-material ban against the United States has been suspended since 2025-11-09
Counter-evidence
- Gallium revenue is extremely small and the by-product effect is unlikely to be material to overall financials
- The March 2026 Middle East conflict halted QatarEnergy's aluminum and helium operations, creating a larger impact on the aluminum business
China Northern Rare Earth

- DoD's $110/kg NdPr 10-year price floor and $400 million equity investment
- Mountain Pass produced 8,900 tonnes in 2025, approximately one-third of U.S. consumption under one estimate, or domestic production under another
Counter-evidence
- The price floor provides a profit floor and reduces the financial impact of supply restrictions

Scenarios and signals
Base/gradual (Tier A): November suspensions extended; licenses selectively granted
Premise: After the two expiry dates of 2026-11-10 and 2026-11-27, China extends the suspensions, but licensing approvals continue to be selectively granted. Low approval rates for heavy rare earths to the United States, Japan and Germany persist, while the extraterritorial 0.1% rule remains nominally effective but is enforced cautiously
The domestic-overseas price gap remains but no longer widens materially; gallium, germanium and rare-earth prices fluctuate at high levels. Downstream companies shift from JIT to safety inventories, increasing working-capital usage. Western replacement-project financing slows because of price uncertainty, and long-term dependence rises rather than falls. The aggregate macro shock remains limited, concentrated in specific-industry margins and delivery delays
Signals to watch
- Ministry of Commerce announcement extending the suspension expiry dates of 2026-11-10 and 2026-11-27
- Improved licensing approval rates for Dy/Tb/Y in markets outside China
- Domestic-overseas spreads in Benchmark/Argus/Platts stop widening
- Changes in corporate safety-stock days and renegotiation pace for long-term contracts
Escalation (Tier B): Suspensions expire without extension; five additional rare-earth controls take effect
Premise: After 2026-11-10 and 2026-11-27, the suspensions are not extended. Controls on the five rare earths added in October—holmium, erbium, thulium, europium and ytterbium—take effect against the United States, expanding the controlled categories from seven to approximately 12, with the extraterritorial 0.1% rule enforced in practice
The controlled rare-earth categories affecting the United States expand, and overseas Dy/Tb/Y spreads widen further. Magnet costs and delivery pressure increase, with more shutdown and delay cases in EVs, wind power and defense. GaN/GaAs and optical-fiber GeO₂ costs continue rising. Compliance costs spread to nearly all rare-earth-containing electronic and mechanical products. Western mine-to-magnet restructuring accelerates, although short-term capacity remains far below requirements
Signals to watch
- Ministry of Commerce announcement not extending the suspensions
- Customs export data, particularly Dy/Tb/Y shipments to the United States, Japan and Germany, continue to decline
- Domestic-overseas spreads in Benchmark/Argus/Platts reach new highs
- MOFCOM announcement of additional entities or categories
- More corporate shutdown and delivery-delay announcements
Confrontation/expansion (Tier C): Additional categories added and third-country transshipment enforcement strengthened
Premise: On the basis of Tier B, tungsten, antimony, graphite, indium, tellurium, bismuth, molybdenum and other items on the watch list are brought under control, while enforcement against third-country transshipment is strengthened
The shock expands from semiconductors and new energy to broader industrial and defense chains. Third-country transshipment channels narrow, and detour routes such as the surge in German gallium imports from the United States are compressed. Structural inflation effects rise at the margin but remain concentrated in specific industries. WTO and reciprocal-measure disputes intensify, while coordinated industrial policies by the G7, DFC, DoD, Australia and Japan accelerate their offsetting response
Signals to watch
- MOFCOM announcement adding tungsten, antimony, graphite, indium, tellurium, bismuth, molybdenum and other categories
- More enforcement and criminal cases involving third-country transshipment
- Escalation of WTO and reciprocal-measure disputes
- Further 1260H updates and progress preparing the indirect-procurement ban between now and 2027-06-30
Failure/easing: Comprehensive minerals agreement or major replacement commercialization
Premise: A minerals/tariff package is reached at milestones such as Xi's visit to the United States on 2026-09-24, China extends the suspensions and relaxes licensing approvals; or a major substitute technology commercializes—such as high-coercivity magnets without heavy rare earths or large-scale GaN-to-SiC conversion—combined with a global demand slowdown
Overseas spreads fall and the two-tier system narrows. Western replacement projects face financing difficulties as prices decline, and long-term dependence rises. The control shock fades into event-driven volatility, with macro and industry effects materially below Tier A; scarcity-based price premiums previously established are unwound
Signals to watch
- A minerals/tariff package reached during Xi Jinping's visit to the White House on 2026-09-24
- Material relaxation of Ministry of Commerce licensing approvals and recovery in export volumes
- A significant narrowing of domestic-overseas spreads
- Commercialization announcements for substitute technologies, including heavy-rare-earth-free magnets and progress in SiC substitution
- Downward revisions to global EV, wind-power and AI capital expenditure
The evidence leans toward the supporting side, but only for a 'structural shock under precision controls' rather than a 'total cutoff': supply-chain concentration, two-tier spreads, halved export volumes and isolated physical shutdowns—airlines and automakers—are hard evidence that the transmission mechanism exists and is already operating. The opposing evidence on suspensions, weak domestic prices, substitution and offsets mainly changes the magnitude and geographic distribution of the shock rather than disproving the mechanism itself.
The decisive reason confidence is 'medium' rather than 'high' is that both sides have several hard pieces of evidence that cannot offset one another. The supporting side has IEA concentration data, Benchmark domestic-overseas spreads (6.8x for dysprosium oxide and 188x for yttrium oxide), a 50% export decline and Reuters-reported airline shutdowns, directly demonstrating that the mechanism exists. The skeptical side also has hard evidence: the U.S. ban was suspended from 2025-11-09, exports to Japan resumed, Japan received 4% of dysprosium imports and Germany 0%, domestic Chinese prices weakened in September 2026, and the Middle East conflict is a clear confounding variable. These facts weaken the inferences about shock intensity and U.S. targeting. Only isolated companies have reached genuine second-order shutdowns, so the mechanism's prevalence cannot be quantified; confidence is therefore not 'high'. However, the skeptical evidence mostly reduces the magnitude and direction of the impact and does not disprove the transmission mechanism, so confidence should not fall to 'low'.
The case for
- The degree of supply-side monopoly is supported by authoritative data and concentration continues to rise: the IEA Global Critical Minerals Outlook 2025 shows China is the highest-output country for 19 of 20 energy-related minerals and accounts for approximately 70% of global refining capacity on average; the top-three refining share rose from 82% in 2020 to 86% in 2024. Gallium has no independent mines, China accounts for more than 85% of refining, U.S. primary gallium production stopped in 1987 and there is no national stockpile; China accounts for approximately 68% of germanium output and GeO₂ used in fiber optics has almost no functional substitute. This makes a tightening of the 'gate' a nonlinear shock for specific links.
- Transmission has moved from prices into physical production rather than remaining a regulatory declaration: yttrium, dysprosium and terbium exports fell approximately 50% versus the 12 months before controls; Dy/Tb prices rose 4–5 times and Y approximately 140 times; Reuters reported in February 2026 that U.S. airlines temporarily halted production because of yttrium shortages; magnet prices rose 1.5–3 times; and Ford and General Motors cut production after April 2025 because of rare-earth shortages. Both first-order pricing and second-order shutdowns have traceable examples.
- The two-tier spread is observable transmission evidence: Benchmark 2026 shows European CIF dysprosium oxide at 6.8 times China DDP and North American CIF yttrium oxide at 188 times China DDP, demonstrating that cross-border flows are being allocated administratively rather than by price. This mechanism does not require a total cutoff.
- The policy tools remain available and a clear escalation path exists: on 2026-06-22, MP Materials, USA Rare Earth and eight other U.S. companies were placed on the comprehensive embargo list. The two suspension expiry dates of 2026-11-10 and 2026-11-27 create binary trigger points, while 'suspension as leverage' continues to restrain foreign investment and compliance decisions.
The skeptical case
- The key qualification 'against the United States' does not fit the facts and data distribution: the gallium, germanium and antimony superhard-material ban against the United States was suspended from 2025-11-09 through 2026-11-27, and exports to Japan have already resumed, with 6,000 kg of gallium exported in 2026-05. Japan received only 4% of its pre-control dysprosium imports and Germany 0%, while the United States obtained some supplies through White House intervention. This suggests a global leverage tool rather than a mechanism whose impact can be extrapolated as a U.S.-specific shock.
- Confounding variables weaken price attribution: the underlying materials explicitly identify the March 2026 Middle East conflict spillover—Qatar's suspension of aluminum and helium operations and disruption to Hormuz passage—as overlapping with the controls to lift gallium prices, since gallium is an aluminum-smelting by-product. Attributing the combined shock to controls alone mistakes correlation for causation.
- Domestic Chinese prices were weak in September 2026: SMM reported a quiet rare-earth market, weaker terbium oxide and praseodymium-neodymium oxide, and the Q2 China praseodymium-neodymium index fell 5%. This shows a split of domestic oversupply and restricted exports rather than a global hard shortage; if supply were truly weaponized, domestic prices should rise simultaneously.
- Substitution and demand-destruction channels are real and accelerated by high prices: SiC partially substitutes for GaN in power electronics and does not require gallium; reduced-dysprosium use, grain-boundary diffusion, ferrite and rare-earth-free motors are advancing; and recycling economics are improving. There is also a self-reversal pattern in which investment builds replacement capacity, China relaxes controls, prices collapse and high-cost new capacity loses money, as seen in solar, lithium batteries and magnets. China has an incentive to ease prices before Western capacity is established.
- Legal and alliance-based offsets mean the chain is not locked in one direction: WTO disputes, G7/DFC/DoD subsidies and price floors, and scaled third-country transshipment—including a 1,111% surge in German gallium imports from the United States in 2022–24—provide routes to circumvent or offset the controls. The only clearly completed second-order shutdown cases are isolated airlines, an insufficient sample to support generalization.
What would invalidate this
- Before 2026-11-10, the Ministry of Commerce announces an extension of the suspension period for the five medium and heavy rare earths added in October against the United States, and before 2026-11-27 it simultaneously extends the suspension of the gallium, germanium, antimony and superhard-material ban—neither track resumes, invalidating the Tier B and Tier C scenarios.
- After either 2026-11-10 or 2026-11-27, the Ministry of Commerce announces restoration or escalation of controls, such as adding tungsten, antimony, graphite, indium, tellurium, bismuth and molybdenum, but also reports a material recovery in rare-earth licensing approval rates to the United States, Japan and Germany—for example, Japan's dysprosium imports recover to more than 50% of pre-control levels versus the current 4%. Volumes rise and prices fall, showing that administrative release offsets 'controls as leverage'.
- Under any authoritative Argus, Fastmarkets, SMM or Platts series, the CIF Europe dysprosium oxide premium versus China DDP narrows from Benchmark Q2 2026's 6.8 times to below 2 times, while the yttrium oxide premium narrows from 188 times to below 10 times. The core evidence of a two-tier system disappears.
- Monthly Chinese customs data show yttrium, dysprosium and terbium exports recovering to more than 80% of the average in the 12 months before controls, reversing the current approximately 50% decline.
- After domestic Chinese rare-earth, gallium and germanium prices weakened in 2026H1—Q2 praseodymium-neodymium index down 5% and terbium oxide/praseodymium-neodymium oxide weak in September—they turn persistently higher and approach overseas prices. This would mean domestic oversupply plus restricted exports has been replaced by a global hard shortage, invalidating the pricing evidence supporting precision controls rather than a total cutoff and the limitation that the shock is modest.
- A major substitute technology is verifiably commercialized: for example, mass production of high-coercivity magnets without heavy rare earths, large-scale conversion from GaN to SiC in AI-server power supplies or EV inverters, or scaled adoption of grain-boundary diffusion/reduced-dysprosium technology in EV traction motors. Higher substitution elasticity would weaken transmission through the magnet segment.
- Third-country transshipment becomes verifiably scaled: for example, German imports of gallium from the United States continue the 1,111% surge of 2022–24 and become normal, or another scaled route emerges to evade the extraterritorial 0.1% rule, such as overseas supply-chain restructuring followed by larger exports to the United States. The controls are circumvented and the transmission chain is interrupted.
- After Xi Jinping's visit to the White House on 2026-09-24, China and the United States reach a comprehensive minerals/tariff package, or the U.S. 1260H indirect-procurement ban, scheduled to take effect on 2027-06-30, is delayed or canceled. The geopolitical premise changes and the scenario basis of the conditional analysis no longer holds.
Limitations
- Information sources are primarily secondary reports and research institutions, including law-firm interpretations, Reuters, Benchmark, Argus, IEA and USGS. The original texts of Ministry of Commerce announcements No. 23/26 of 2026, the USGS Mineral Commodity Summaries 2026 sections on gallium, germanium and rare earths, and the original IEA GCMO 2025 have not been locked down. Price and export-volume data use different definitions—for example, gallium prices range from $2,100 to $2,269 to $3,050/kg, while germanium prices range from $2,500–3,500 to $8,597/kg—and have not been unified to a single standard.
- The tool stopped at the search limit. Company-level financial exposure for MP Materials, USA Rare Earth, IQE, Qorvo/Skyworks, China Northern Rare Earth and Yunnan Germanium has been identified only structurally; audited financial figures for revenue, gross margin, inventory and capital expenditure were not obtained, so directional judgments on financial transmission lack quantitative support.
- The assessment of how much has already been priced in is incomplete: no clear evidence was found on how the binary outcomes around the two November suspension expiry dates are reflected in commodity forwards or implied stock-option volatility. Daily-limit moves followed by retracement among Chinese metal producers on the control-announcement date are short-term sentiment observations, and relative performance and valuation-percentile data for MP, USAR, IQE and Qorvo around China's 2026-06-22 list and the 2026-06-08 1260H list were not obtained.
- The sample is insufficient to quantify the mechanism's prevalence: only isolated company cases have completed genuine second-order shutdowns—the airline shutdown attributed to yttrium shortages reported by Reuters and automaker production cuts after April 2025—so the probability and distribution of second-order shutdowns at the industry level cannot be inferred.
- A clear confounding variable has not been removed: the March 2026 Middle East conflict spillover, including QatarEnergy's suspension of aluminum and helium operations and disruption to Strait of Hormuz passage, overlapped with gallium's price rise as an aluminum-smelting by-product. Attributing the price move solely to Chinese controls would overstate their effect, and this analysis did not cleanly separate the factors.
- The implicit assumptions in the time window have not been verified: the actual enforcement of the extraterritorial 0.1% rule, the binary outcome at the November expiry dates and the restraining effect of 'suspension as leverage' on corporate decisions are all institutional judgments. The best proxy for actual control intensity—the licensing approval rate—has not been obtained as a continuous, comparable official or customs time series.
- Country-distribution data—Japan receiving 4% of dysprosium imports, Germany 0% and the United States obtaining some supplies through licenses—are snapshots from a single point in time. Continuous tracking of approval rates for the United States, Japan and Germany is unavailable, limiting the robustness of the inference that U.S.-specific targeting is weakened.
- The pace at which substitution and offsets materialize is highly uncertain. Rio Tinto's Quebec gallium project (scheduled for 2027), Nyrstar Hobart (approximately five years), the DoD-supported 10X magnet plant (target 2028) and the USAR Oklahoma magnet plant (2028) are all planned or construction-stage targets; delays and financing risks were not incorporated into the sensitivity analysis.
