White House Gets Small Rare Earth Win, but China's Export Regime Is Here to Stay

Why It Matters

The continued Chinese export regime threatens US aerospace and chip supply chains, raising costs and potential capacity constraints for high‑tech manufacturers. Securing stable access to yttrium, scandium and indium is critical for maintaining competitiveness in next‑generation photonic and semiconductor technologies.

Key Takeaways

• China will address US concerns on yttrium, scandium, indium shortages
• Export controls on rare‑earth processing tech remain unchanged
• Indium shipments to US down 77% since Feb 2025
• Coherent holds 40% global market share in indium‑phosphide components
• One‑year truce on broader rare‑earth restrictions expires November

Pulse Analysis

China’s dominance over rare‑earth minerals has long been a strategic lever in global technology supply chains. Yttrium, scandium and indium are essential for heat‑resistant coatings, high‑strength alloys and semiconductor photonics, yet Beijing’s export controls, first imposed in April 2025, have throttled U.S. access. The recent summit concession—limited to addressing specific shortages—does not dismantle the broader regime, leaving manufacturers to navigate a patchwork of licences that can delay critical projects and inflate input costs.

Indium, highlighted for the first time by the White House, illustrates the acute pressure on the semiconductor sector. Its compounds, indium phosphide and indium tin oxide, power next‑generation photonic chips, optical lasers, and LED displays. Since February 2025, Chinese shipments to the United States have plunged 77%, forcing firms like Coherent, which commands 40% of the global indium‑phosphide market, to confront higher procurement expenses and uncertain capacity expansion. The slowdown threatens AI data‑center rollouts that rely on photonic interconnects, prompting U.S. companies to seek alternative sources or invest in domestic processing capabilities.

For policymakers, the outcome underscores the need for a multi‑pronged strategy. Short‑term measures may include targeted licence accelerations for aerospace and chipmakers, while longer‑term plans should focus on diversifying supply through allied partners, recycling initiatives, and incentivizing domestic rare‑earth mining. As the one‑year truce on broader restrictions approaches its November expiry, the industry will watch closely for any shift that could reshape the competitive landscape of high‑tech manufacturing.
