LS Cable Eyes U.S. Rare-Earth Magnet Plant

South Korea’s LS Cable & System is studying a permanent magnet manufacturing facility with Chesapeake, Virginia, as a candidate site, currently at the feasibility stage.

The proposal targets downstream NdFeB magnet production rather than mining or separation, aiming to capture higher-value stages of the supply chain where margins and geopolitical leverage concentrate. China still dominates roughly 80–90% of global NdFeB magnet output, and U.S. capacity remains thin and reliant on imported separated oxides and metals.

Co-locating a magnet line near LS Cable’s existing submarine cable operations could deliver logistics, workforce, and customer adjacency advantages for offshore wind, grid infrastructure, and electrified transport markets. Buyer-side pressure from industrial customers helps explain the move as much as policy incentives.

Significant hurdles persist: secure access to separated feedstock, specialized metallurgical processes for alloying and sintering, management of waste and emissions, permitting timelines, and firm long-term offtake agreements. None are solved simply by choosing a U.S. ZIP code.

Still, LS Cable’s interest is a concrete industrial test of whether the United States can host commercially viable magnet manufacturing. Even a modest plant would incrementally de-risk allied supply chains and serve as a practical proof point for reshoring efforts.
