USA Rare Earth Breaks Ground on $1.2B South Carolina Magnet Plant

USA Rare Earth broke ground on an 800,000-square-foot magnet manufacturing facility in Blacksburg, South Carolina on September 11, representing a $1.2 billion investment expected to produce 6,400 metric tons per annum of neodymium-iron-boron magnets by 2028. Combined with its Stillwater, Oklahoma expansion, the company will reach 10,000 tpa of domestic NdFeB capacity, part of a US-Europe effort to reduce dependence on China's 90% global control of processed rare earth output.

The Blacksburg facility closes a 30-year supply-chain wound but doesn't eliminate the China dependency — it reduces it. At 10,000 tpa, USA Rare Earth supplies roughly 25-30% of US defense demand for NdFeB; the remainder still flows through Chinese processors or allied secondary sources (Japan, South Korea).

The real constraint is not magnet production but rare earth ore processing: China controls the refining step, not just the mining. Carester's European expansion (minority stake finalized July 2026) signals USA Rare Earth is hedging against US-Europe supply divergence, but a single European processor cannot absorb both continents' demand if China tightens export controls — which it will, the moment US-Taiwan tensions spike.

WHY IT MATTERS

USA Rare Earth now has two commissioned production lines (Stillwater operational, Blacksburg 2028 commissioning) that collectively close a critical gap in the US defense-industrial base — NdFeB magnets are irreplaceable inputs for missile guidance systems, radar, electric propulsion, and hypersonic platforms.

The 10,000 tpa target is the first domestic capacity at scale since the 1990s; without it, every advanced weapons platform built in the US depends on either Chinese supply or spot-market acquisitions at 3-5x cost. Watch whether DoD's FY27 supplemental includes direct procurement commitments (advance purchases of magnet inventory) to de-risk the 2028 ramp — that would signal confidence in the timeline and lock in capacity before competitors bid against US primes for output.

WHAT THIS DOESN’T TELL US

Does USA Rare Earth have binding offtake agreements with Raytheon, Lockheed, or General Dynamics for the Blacksburg production run, or is the company banking on spot-market sales and government incentives to sustain the capex through 2028?
