China Rare Earth Export Ban & Defense Critical Minerals

The US relies on imports for 100% of antimony, 100% of gallium and 100% of heavy rare earths, while China refines 99.5% of heavy rare earths.

How Export Controls Hit the Defense Industrial Base

China controls 65.0% of antimony refining and 98.5% of gallium refining. Antimony is quoted near $17.5/lb against a $6.2/lb baseline, and the Defense Logistics Agency stockpile covers about 5.2 months. Systems exposed include 155mm Shells, F-35 AESA, Patriot, Javelin.

The policy response includes a $75M Defense Production Act award and $1.8B in Ex-Im Bank financing interest for a domestic antimony project.

Frequently asked questions

What is the impact of the China rare earth export ban and China restriction on rare earths on US national defense?

The china rare earth export ban and escalating china restriction on rare earths represent a direct strategic threat to Western defense readiness. Beijing controls over 65% of global antimony refining and 98% of gallium, meaning a comprehensive china ban on critical minerals exposes the us critical minerals shortage across frontline weapons platforms such as 155mm artillery primers, F-35 AESA radars, and Virginia-class submarines.

Which materials are prioritized on the critical minerals list US and how do gallium and germanium export restrictions affect tech?

The critical minerals list us published by the Department of the Interior designates 50 commodities vital to economic and national security, prominently featuring Antimony (Sb), Gallium (Ga), Germanium (Ge), and Heavy Rare Earths (Dy/Tb). Tightening gallium and germanium export restrictions severely limit dual-use radio-frequency semiconductors and infrared optical manufacturing, pushing military contractors to expedite domestic recycling and scrap extraction.

How does Perpetua Resources antimony solve the munitions chokepoint and why is antimony price per pound surging?

Perpetua Resources antimony from the Stibnite Gold-Antimony Project in Idaho is the premier domestic solution to replenish depleted NATO munitions primers. Because the US has zero commercial antimony production and the National Defense Stockpile holds only ~5.2 months of reserves, the antimony price per pound has skyrocketed from a $6.2 baseline to over $17.5/lb ($38,500 per ton), prompting a $75 million DoD DPA Title III grant and $1.8 billion Ex-Im Bank financing for Perpetua (PPTA).

Which are the best antimony stocks to buy, gallium and germanium stocks, and rare earth stocks 2026 for investors seeking to invest in critical minerals?

For investors evaluating how to invest in critical minerals, the premier critical minerals stock list and top antimony stocks to buy include Perpetua Resources (NASDAQ: PPTA) and United States Antimony Corporation (NYSE: UAMY). Key gallium and germanium stocks include Teck Resources (TECK) and Umicore. Among rare earth stocks 2026, market leaders include MP Materials (NYSE: MP), operating the Mountain Pass mine in California, and Lynas Rare Earths (LYSCF), constructing a DoD-funded heavy rare earth separation plant in Texas.
