Washington's New War on China's Mineral Grip

The two July directives

• July 30 — presidential determination. Trump signed a determination handing the Commerce Department power under the Defense Production Act "to keep critical minerals and materials from leaving the country."
• July 20 — Executive Order 14415. Ten days earlier, an order directing the Pentagon "to trace every critical material in its weapons and defense systems back to the mine it came from," to "secure its supply chains against physical, cyber, and economic subversion." Prins' translation: "to force out suppliers along that chain that are tied to China."

The deadline that matters — January 1, 2027

• That's when the Pentagon rules "will bar Chinese rare-earth magnets from its weapons systems." As of today the U.S. still buys most of those magnets from China — "and China has already restricted that supply."

China's side of the board — April 2025 controls, and a truce clock running to Nov 10, 2026

• In April 2025 Beijing placed export controls on seven rare earths and the magnets built from them — components of "fighter jets, missiles, cars, and wind turbines." That restriction "remains in force and will continue to be a factor."
• When China moved to widen its controls last October, Trump and Xi struck a truce that paused the new measures for one year — to November 10, 2026. Two deadlines therefore sit six weeks apart: the truce expiry, then the Pentagon magnet ban.

The dependency table — how short the U.S. actually is

• The U.S. imports "every ounce" of the gallium and natural graphite it uses, 99% of its uranium, 91% of its antimony ("the hardener in armor-piercing rounds"), and 60% of its aluminum.
• On the other side, China refines "more than 80% of the world's tungsten and close to 90% of its rare earths." The U.S. produces no gallium or natural graphite and accounts for just 15% of global rare-earth mine production.
• Prins frames the gap as "a growing economic and national security crisis" — the U.S. is "short the very raw and refined metals needed to arm its military and rebuild its energy and infrastructure sectors," after a catch-up position "spanning decades."

The uranium footnote — a Russian waiver that expires in 2027

• Enriched uranium "powers 19% of the American energy grid" and "still comes in part from Russia, under import-ban waivers that expire in 2027" — a second 2027 cliff sitting behind the magnet ban.

Where the capital goes — refiners and processors, not just mines

• "This massive gap in the U.S. is forcing billions in federal funding and private capital into the processors, refiners, and alternative suppliers trying to build a supply chain outside China." The stated destination of the money is the midstream, not the ore body.

An eighteen-month campaign, not a one-off

• The July actions are "the latest set of directives in a now eighteen-month campaign aimed at leveling the critical-minerals playing field through U.S. government equity stakes, permit acceleration, trade controls, and other measures."
• March 2025: an EO expanded mineral-production mandates to cover copper, uranium, gold and potash, invoking the Defense Production Act — "the Korean War law from the early 1950s that lets Washington fund and guarantee purchases of domestic output" — and redirected the Development Finance Corporation, built to fund projects in developing countries, "to lend to domestic mines for the first time."
• February 2026: Project Vault — a $12 billion mineral reserve built on a $10 billion Export-Import Bank loan, "the largest in the bank's 92-year history," which convened delegates and leaders from 54 countries in Washington to discuss building supply chains outside China.
• June 2026: another $2.9 billion committed to rare-earth and magnet production and, "for the first time, opened military bases to mineral processors."

What the July 20 order actually changes — the waiver loophole closes

• Defense contractors were "already prohibited from putting Chinese rare-earth magnets, tungsten, tantalum, and molybdenum in weapons, yet they kept doing it anyway through nonavailability waivers, the claim that the material could not be found anywhere else."
• From January 1, 2027, a waiver requires "a formal plan showing that it made exhaustive efforts to find a compliant source and setting a timeline to remove Chinese material from its supply chain." The order "states outright that having no U.S. supplier is no longer an excuse."

The bill-of-materials rule — 180 days to write it, every tier to comply

• The Pentagon has 180 days to write rules requiring "every prime and subcontractor, at every tier, to map its supply chain down to the raw material and submit a full bill of materials, with suspension or termination for those that do not."
• The investable consequence, in her words: "Every producer of those metals outside the restricted countries becomes a source the Pentagon's contractors now have to qualify." Compliance demand, not just policy sentiment, is what re-rates ex-China supply.

The July 30 determination — scrap and spent batteries stay home

• It lets Commerce "block the export of critical minerals, including the metal locked inside dead permanent magnets and spent lithium-ion batteries that can be recycled at home."
• The purpose: "to keep American scrap and byproducts in the country instead of shipping them abroad for other countries to potentially use, weaponize or redeploy elsewhere" — recycling and secondary supply treated as a strategic reserve.

Copper — the second-most-used defense material, now with $350B+ of lending behind it

• Copper is "the second-most-used material by weight in the defense sector, ranging from artillery driving bands to aircraft landing gear," and it is one of the materials the July 20 mapping rule forces contractors to trace to source.
• Permitted U.S. copper projects "can now qualify for federal financing through programs at the U.S. Department of Energy and the Pentagon's Office of Strategic Capital, which together hold more than $350 billion in lending authority."
• Price context: copper "trades near $6.43 per pound now, just off the record $6.71 it set in May, as AI data centers drive demand well above and beyond what miners can currently supply."

Aluminum — caught by both directives without being named in either

• Aluminum "is not an explicitly covered industrial material," but the July 20 order "forces contractors to trace every material in a weapons system back to its smelter and to qualify a domestic or strategically aligned source for anything coming from a China-linked supplier. That includes aluminum."
• The July 30 determination works "on the post-production side": Commerce can keep American aluminum scrap and spent material from being exported, "so a country down to four operating smelters recycles what it has instead of shipping it abroad."

Aluminum tariffs and the first new U.S. smelter in ~45 years

• China produces "about 60% of the world's primary aluminum." In June 2025 the administration doubled the Section 232 tariff on aluminum to 50%; in July 2026 it added an incentive giving companies that invest in domestic smelting "a reduced tariff on the primary metal they still import" — a carrot bolted onto the stick.
• A 500,000-ton plant backed by a Department of Energy award — "the first new U.S. smelter in some 45 years" — is now in development. The Energy Secretary's stated goal: "revitalizing this country's manufacturing base and reducing our reliance on foreign suppliers."

Where she's pointing next — two gated picks

• Her "Dig Deeper" close: "We see these policies driving more capital into domestic and American partner supply chains, particularly where defense and energy infrastructure intersect." That intersection is the screen.
• This month's research focuses on copper and aluminum: "Both our Pulse Premium and Founders+ issues due out later this month will examine two companies operating at different points in those supply chains." Neither name is disclosed here, and neither is captured in this archive.
