The global supply chain for high-tech manufacturing remains in a state of high alert as the “weaponization” of critical minerals moves from theoretical risk to operational reality. In the first half of 2026, the industrial world is navigating a fragile reprieve following China’s decision in late 2025 to temporarily suspend its strict export ban on gallium, germanium, and antimony to the United States.
However, the underlying regulatory framework: a sophisticated system of export licensing and dual-use controls: remains firmly in place. For operators in the semiconductor, aerospace, and defense sectors, the “spread” between domestic Chinese prices and international market rates serves as a primary barometer for geopolitical tension and future supply security.
The Weaponization of the Periodic Table
China’s export controls are not merely administrative hurdles; they are strategic tools deployed in a broader technological “Cold War.” By restricting materials like gallium and antimony, Beijing targets the foundational building blocks of modern military and consumer technology.
Gallium is essential for gallium nitride (GaN) semiconductors, which allow for higher power density and efficiency in 5G base stations and advanced AESA (Active Electronically Scanned Array) radar systems. Antimony, meanwhile, is a critical flame retardant and a vital hardening agent in lead-acid batteries, as well as a key component in infrared sensors and armor-piercing ammunition.
The impact of these controls is best observed through price spreads. Historically, when export licenses are tightened, the price of these materials in Rotterdam or New York can surge to nearly double the domestic price inside China. This divergence creates an “information lag” where Western manufacturers face spiraling costs while Chinese competitors enjoy subsidized, stable access to the same raw materials.
Analyzing the Price Spreads: Gallium and Antimony in 2026
As of April 18, 2026, market data suggests a cautious stabilization, but volatility remains higher than the five-year average.
Gallium Dynamics
In 2023, following the initial announcement of controls, international gallium prices spiked by over 40% in a single month. By mid-2025, prices reached peaks of $687 per kg on international exchanges. Today, even with the current suspension of the U.S. ban until November 2026, the international premium remains significant. Manufacturers are currently paying a “geopolitical insurance premium,” as China continues to monitor the end-use of every shipment through its permit system. You can track the evolution of these markets in our analysis of gallium and germanium supply 12 months after controls.
The Antimony Crunch
Antimony has proven even more sensitive to supply shocks. Because China accounts for nearly half of global mine production and a much higher percentage of refined output, any friction in the export process ripples through the defense industry. In late 2024, when the ban was at its strictest, European chemical giants were forced to declare force majeure on certain deliveries. The current price spread reflects a market that is desperately trying to build stockpiles before the November 2026 deadline, when China could potentially re-impose total restrictions.
Strategic Importance: Why These Minerals Matter for Defense
The strategic importance of these minerals cannot be overstated. In the defense sector, “critical” is an understatement; these materials are irreplaceable in the short to medium term.
- Semiconductors and Radar: Gallium is the “silicon of the future” for high-frequency applications. Advanced radar systems used in the F-35 and other next-generation platforms rely on GaN technology. If the supply of gallium is choked, the production of these systems faces multi-year delays.
- Precision Munitions: Antimony is used in the primers of nearly every type of ammunition. For a military-industrial base already strained by global conflicts, a shortage of antimony represents a direct threat to national security readiness.
- Optics and Night Vision: Germanium and antimony are essential for the lenses and sensors that give Western forces an edge in low-light environments.
This tension has accelerated a global shift in mineral procurement, similar to the strategic realignment seen in the DRC regarding copper supply.
Western Response: Miners and Policy Makers Step Up
The “China Plus One” strategy has moved from the boardroom to the mine site. Western miners are racing to fill the vacuum, supported by unprecedented government incentives and defense funding.
Perpetua Resources and the Stibnite Gold Project
In the United States, Perpetua Resources’ Stibnite Gold Project in Idaho has become a symbol of domestic mineral independence. While primarily a gold mine, the project contains the largest known antimony deposit in the U.S. The Department of Defense has recognized this, providing significant funding to fast-track the project’s development. By 2026, Perpetua is moving closer to production, representing a critical bridge for the U.S. defense supply chain.
USA Rare Earth and Domestic Processing
USA Rare Earth and other junior miners are focusing not just on extraction, but on the refined processing capabilities that China currently dominates. The goal is to create a “closed-loop” supply chain where materials are mined, refined, and manufactured into components within North America or allied nations. This trend is mirrored globally, as seen in Greenland’s struggles to launch its mining industry and Sweden’s Per Geijer rare earth project.
Strategic Stockpiling
Beyond mining, the U.S. National Defense Stockpile is being replenished with urgency. Legislators are considering mandates that would require a certain percentage of critical minerals used in government contracts to be sourced outside of “countries of concern.”
Forecast 2026: Pricing and Supply Chain Risks
The outlook for critical mineral pricing through the remainder of 2026 is defined by a “countdown clock” toward November 27, 2026: the date the current Chinese export suspension is scheduled to end.
- Base Case: Prices will likely trade in a elevated range ($550–$650/kg for gallium) as companies aggressively stockpile. The spread between Chinese and international prices will remain at 15–25% due to the administrative costs of the licensing regime.
- Bull Case (Supply Tightening): Should geopolitical tensions rise over Taiwan or trade tariffs, China may begin “informal” slowdowns of license approvals before the November deadline. This would likely cause international prices to re-test the $700/kg mark for gallium and record highs for antimony.
- Bear Case (Market Oversupply): If Western projects come online faster than expected and the U.S. achieves a diplomatic breakthrough with Beijing, we could see a moderate softening of prices. However, given the technical challenges of mining and refining these materials, a major price collapse is unlikely.
The industry is also watching how new technologies, such as deep-sea mining, might eventually supplement land-based supplies, though these remain years away from commercial scale.
Operational Takeaways for Decision-Makers
For operators and investors, the “spread” is more than just a number; it is a signal of risk. Those who fail to diversify their supply chains now are effectively betting on the continued benevolence of a strategic competitor.
- Inventory Management: The “Just-in-Time” model is dead for critical minerals. Manufacturers are shifting to “Just-in-Case” strategies, maintaining 12–18 months of physical inventory.
- Contractual Shielding: New contracts are increasingly including “geopolitical force majeure” clauses and price escalation formulas tied specifically to non-Chinese indices.
- Substitution Research: R&D departments are being tasked with finding alternatives to antimony and gallium, though for many defense applications, no viable substitutes exist yet.
The 2025-2026 reprieve in Chinese export controls should be viewed as a window of opportunity, not a permanent return to normalcy. As the PDAC 2025 conference highlighted, the era of “easy” mineral procurement is over. The coming months will determine which Western companies have successfully decoupled and which remain vulnerable to the next pivot in Beijing’s trade policy.
