Critical Minerals Weekly — Mar 10, 2026

China's export control suspension on rare earths, gallium, germanium, and antimony expires on November 10, 2026, and almost nobody's supply chain is actually ready for when the clock runs out. Meanwhile, the week delivered a string of signals that all point the same direction: the real bottleneck isn't ore in the ground — it's who owns the chemistry, the patents, and the processing plants that turn rocks into things that matter. From a first-ever antidumping case on battery electrolyte salt to Australia's flagship refinery running about 40% over its original budget as of March 2026 reporting, the gap between policy ambition and industrial reality got harder to ignore.

If you work in defense electronics, EV manufacturing, or semiconductor supply chains, the most important date on your calendar isn't a product launch — it's November 10, 2026.

China agreed to suspend its sweeping October 2025 rare earth export controls from November 7, 2025, pending bilateral negotiation; that suspension is scheduled to lapse on November 10, 2026. A second suspension covering US-specific licensing on gallium, germanium, antimony, and superhard materials runs until November 27, 2026. But the underlying architecture — the licensing system, the military end-use ban, the April 2025 requirements on medium and heavy rare earths — remains fully intact. In less than three years, Beijing has built a comprehensive, dynamic control system that functions as a policy lever, not a wall — calibrated for both escalation and de-escalation.

What's happening with the runway? Not much. Former President Trump threatened to impose 200% tariffs if China fails to supply rare earth magnets, suggesting Washington remains dissatisfied with progress (threats made publicly in 2024–2025). Beijing's 2026 updates to import/export licensing now tie categories more explicitly to its Dual-Use Items Export Control List — quietly lowering the bar for future tightenings without any high-profile legislation.

The suspension is not deregulation. It's a countdown. The question to put to your tier-1 suppliers right now: what's your contingency if those controls snap back in November?

Most people think about lithium carbonate when they think about battery supply risk. They're missing a quieter chokepoint.

On March 5, 2026, Orbia Fluor & Energy Materials filed the first-ever US antidumping and countervailing duty petition against Chinese lithium hexafluorophosphate — LiPF₆, the electrolyte salt dissolved in the liquid inside virtually every commercial lithium-ion battery. It's the medium that lets lithium ions shuttle between anode and cathode. Without it, the battery doesn't work. Full stop.

China dominates LiPF₆ production the way it dominates most battery chemistry processing: through years of scaled capacity, vertical integration, and prices Western producers can't match without government support or trade relief. Orbia is one of the very few non-Chinese producers with meaningful scale.

The timing is loaded. In July 2025, China added lithium battery production technologies — not just materials, but the process know-how itself — to its restricted export catalogue. Building a non-Chinese cathode plant just got harder. And if antidumping duties land on Chinese LiPF₆, every battery cell made in the US gets more expensive unless domestic production scales fast. Watch for the USITC preliminary determination within 45 days of the petition filed March 5, 2026.

The rare earth market is splitting into two tiers, and you want to know which one you're sourcing from.

Chinese export quotas could displace as much as 13,000 metric tons of neodymium-praseodymium demand in 2026 — the rare earth blend that makes permanent magnets in EV motors, wind turbines, and guided munitions. A separate estimate suggests the US holds roughly two months of rare earth supplies in strategic and commercial stockpiles as of March 2026. That's not a buffer; that's a fire sale waiting to happen.

The commercial response is more interesting than the panic. Lynas and Japan Australia Rare Earths extended a supply framework through 2038, with structured price floors and upside-sharing — the kind of bankable contract that actually finances new separation plants. Separately, Australia and Japan signed three joint ventures to process NdPr in northern Australia, targeting ~4,000 tonnes of separated output by 2028.

The lesson: commercial offtake, not policy statements, is what moves tonnage from PowerPoint to plant.

The country that produces roughly 27% of the world's copper inaugurated José Antonio Kast yesterday — and buried in his cabinet is a detail most coverage skipped. His government is merging the Mining and Economy ministries and handing the combined portfolio to agronomist Daniel Mas. The Chilean Mining Chamber is unsettled; prior attempts to fold mining into broader economic portfolios produced poor outcomes.

The sector needs an estimated $105 billion in investment through 2034, and copper output already fell 2% in 2025 amid declining grades. Kast ran on deregulation, but his coalition controls roughly a quarter of the lower house, meaning legislation requires centrist negotiation. Meanwhile, a strike at Capstone's Mantoverde mine has cut production to 30% of capacity since March 7, 2026 — a reminder that even friendly policy environments can't eliminate operational risk.

Adding geopolitical spice: President Xi congratulated Kast on his election, celebrating the bilateral relationship, just as Washington moves to expand its influence in Latin America. Santiago is being pulled in two directions. Watch the Codelco-SQM joint venture and the Maricunga lithium reviews for the first real policy signals.

The world's largest automaker is recycling used EV batteries to help power Mazda's production line — a factory-floor proof of concept for "second-life" battery applications. Batteries too degraded to power a car can still do stationary energy storage, keeping their lithium, nickel, cobalt, and manganese in service years longer before reaching a recycler.

This is the demand-side math that changes the minerals equation. Globally, recyclers could supply about a third of the lithium, nickel, and cobalt needed for batteries by 2040. Second-life deployment extends that timeline further — circular supply in two stages.

The week also delivered a cascade of recycling policy moves: Colorado is considering measures to make automakers responsible for end-of-life battery collection. Stena Recycling in Sweden is investing in safe handling and pre-treatment capacity. Hong Kong launched its first large recycling plant as a policy pilot. A Kenyan project began converting spent batteries into "black mass" for later refining. And the DOE opened a $355 million funding window for recovering critical materials from industrial waste.

Governments are attacking this at two levels: make recycling work reliably, and push midstream capacity away from single-country dominance. Every second-life deployment and recycling plant is a small hedge against the processing geography that makes primary supply so geopolitically fraught.
