## What to know

- South Korea lifted US rare earth oxide imports to $19.06 million, raising America's import share to 21.2%
- China retained a 47.5% share at $43.91 million as component makers absorb Western material premiums
- Pentagon rules mandate the complete removal of Chinese rare earth materials from defense chains by Jan. 1, 2027

The Korea Customs Service reported Sept. 11 that inbound shipments of American rare earth oxides jumped to $19.06 million, more than doubling the United States' share of the country's intake.

The intake of American material accounted for 21.2% of South Korea's $89.53 million total rare earth oxide imports. That represents an 11.5 percentage point increase from the 9.7% share recorded across 2023.

Total imports from the United States in the seven-month span exceeded the $11.56 million recorded for the entire previous year. The shift reflects urgent efforts by industrial procurement desks to secure alternatives to Chinese supply.

South Korea relies on rare earth oxides — chemical compounds refined from mined ores — to manufacture high-strength permanent magnets. Those magnets power electric vehicle traction motors, wind turbine generators and defense guidance hardware.

China's Ministry of Commerce has progressively widened export licensing restrictions on critical minerals, including heavy rare earths and processing technology. Those controls forced South Korean manufacturers to hedge against sudden border closures.

Shipments from China still totaled $43.91 million during the period, representing 47.5% of South Korea's total imports. That marked a modest decline from China's 49.0% share in 2023, when deliveries reached $56.30 million.

The sudden rise in American material also highlights a bottleneck inside the United States supply chain. Washington has poured billions of dollars into domestic mining and separation projects to counter Beijing's dominance.

However, the United States lacks midstream facilities to convert those oxides into metals and finished sintered neodymium magnets. American producers have therefore routed separated materials across the Pacific to established Asian fabricators.

Annual production of rare earth permanent magnets inside the United States remains below 1,000 tons. Japan produces between 10,000 and 15,000 tons annually, while South Korea produces roughly 2,000 to 3,000 tons.

American producers have turned directly to South Korean and Japanese processing floors. MP Materials, Energy Fuels and Phoenix Tailings have all directed commercial shipments to Asian manufacturing hubs.

MP Materials ceased shipping raw rare earth concentrate from its Mountain Pass mine in California to China. The company now sells separated neodymium-praseodymium oxide to allied buyers while finishing its own magnet plants.

South Korean magnet maker Seong-An signed a purchase agreement with MP Materials for 240 tons of rare earth oxide per year. The deliveries feed commercial production of magnet-grade metals destined for non-Chinese automotive supply chains.

POSCO International reached an agreement with Energy Fuels to source rare earth oxides from the White Mesa Mill in Utah. POSCO International uses the raw feed to supply traction motor cores for global automakers.

POSCO International also partnered with ReElement Technologies on a project targeting 3,000 tons of annual rare earth oxide refining. The commercial lines aim to supply dysprosium and terbium for high-temperature motor magnets.

This procurement pivot carries measurable cost friction for South Korean fabricators. Non-Chinese separated oxides trade at substantial premiums due to limited refining capacity outside China.

In Western spot transactions, heavy rare earths like dysprosium oxide have commanded prices exceeding $2,300 per kilogram. That level represents a multiple over domestic Chinese quotations, squeezing margins for downstream motor producers.

Automakers selling into North America are pressing suppliers to absorb those higher input costs. The United States Inflation Reduction Act conditions clean-vehicle consumer tax credits on sourcing critical minerals outside foreign entities of concern.

Meeting those sourcing thresholds requires verifiable non-Chinese provenance from the mine through chemical separation. South Korean component suppliers are paying the material premium to maintain eligibility for vehicle subsidies in North America.

South Korea's Ministry of Trade, Industry and Energy has urged domestic industrial groups to accelerate supply-chain diversification. The ministry operates early-warning mechanisms tracking port delays and quota restrictions across ten strategic mineral categories.

The customs agency did not publish company-specific transaction prices per kilogram, and the trade ministry has not disclosed the volume of American oxides absorbed into national stockpiles.

Procurement schedules face an immediate compliance benchmark. The United States Department of Defense has set a Jan. 1, 2027 deadline requiring defense contractors to eliminate Chinese rare earth materials from their supply chains.

That regulatory deadline is forcing allied manufacturers to complete metallurgical qualification cycles for American oxides ahead of the 2027 cutoff. Deliveries of non-Chinese feedstock to South Korean processing facilities are scheduled to expand accordingly.
