China’s rare earth exports to US surge, giving aerospace manufacturers room to breathe

For more than a year, US aerospace manufacturers have been rationing a material most people have never heard of. Yttrium oxide, a rare earth element essential for keeping jet engine components from melting at extreme temperatures, became scarce after China locked down exports in April 2025. Now, the spigot appears to be opening again, at least partially.

Chinese exports of yttrium oxide to the US reached 29 metric tons in July 2026, the second-largest monthly shipment since those controls took effect. Permanent magnet exports followed a similar trajectory, hitting 647 tons in July, also the second-highest monthly volume in the post-controls era.

Why yttrium matters more than you think

Yttrium oxide forms the backbone of thermal barrier coatings on jet engine turbine blades, the thin layers that allow metal to survive temperatures that would otherwise turn it into expensive soup. Without reliable yttrium supply, aerospace production lines slow down, maintenance cycles get delayed, and costs spike.

China dominates global rare earth production and refining capacity by a wide margin. When Beijing imposed stringent export controls in April 2025, the downstream effects were immediate and painful. Yttrium prices surged to record levels, and US manufacturers found themselves scrambling to secure alternative sources.

The July shipment numbers suggest Beijing is selectively easing the pressure. While US-bound exports are climbing, shipments to Japan remain severely restricted. Exports of yttrium, terbium, and dysprosium to Tokyo are still running at a trickle, reflecting a distinctly frostier diplomatic relationship.

Diplomacy driving the cargo ships

The timing of this export increase is not coincidental. Chinese President Xi Jinping has upcoming trade talks scheduled at the White House, and the surge in rare earth shipments reads like a negotiating gesture delivered in metric tons rather than diplomatic cables.

This pattern has precedent. Beijing has historically used rare earth supply as a lever in trade disputes, most notably during its 2010 export restrictions targeting Japan after a maritime territorial conflict.

The permanent magnet numbers tell a parallel story. At 647 tons in July, these shipments feed into everything from electric vehicle motors to precision-guided munitions. The April 2025 controls had exposed just how dependent the US defense industrial base remains on Chinese supply.

What this means for the supply chain and markets

US aerospace and defense companies that had been managing through material shortages now have somewhat more room to operate. Production schedules that were at risk of slipping due to yttrium rationing can stabilize. Procurement teams that had been paying record prices for spot-market rare earths may see some cost relief.

Australia’s Lynas Rare Earths and Canada’s Neo Performance Materials are among the companies attempting to build non-Chinese supply chains, but their combined output remains a fraction of what China produces.

The divergence between US and Japanese treatment is worth watching closely. If Beijing continues to restrict exports to Tokyo while loosening them for Washington, it signals a strategy of dividing allied responses. Japan’s advanced manufacturing sector, particularly its automotive and electronics industries, depends heavily on the same rare earth elements now flowing more freely to the US.
