China Leads ISO Rare Earth Standards as U.S. and Europe Build Counterweights

Highlights

• China holds the ISO/TC 298 secretariat and chairmanship through 2027, covering standards from mining to recycling across 15 published rare earth standards.
• Europe's CEN/TC 472 produced its first magnet-focused standard CEN/TS 18263:2026, directly tied to the Critical Raw Materials Act requirements.
• The U.S. launched its ISO Critical Minerals Standards Coordination Group in October 2025 to strengthen American influence in rare earth standard-setting.
• Canada and Australia are advancing traceability, certified reference materials, and market architecture standards as part of a broader G7 critical minerals roadmap.
• Standards increasingly act as qualification gates for offtakes, government procurement, and premium markets, making them a form of industrial policy.

China does not “own” international rare-earth standards, but it has the clearest first-mover advantage in writing the industry's technical rulebook (opens in a new tab). Beijing's Standardization Administration of China (SAC) holds the secretariat of ISO/TC 298 Rare Earth, the committee is chaired by China's Haifeng Liu through 2027, and its scope reaches from mining and separation through oxides, metals, alloys, testing, recycling, and traceability. ISO/TC 298 now lists 15 published standards and seven more under development. That leadership follows industrial reality. China produced about 90% of globally refined magnet rare earths and 90%+ of sintered permanent magnets in 2025.

REEx Insight: Whoever Defines “Qualified” Helps Define the Market

Rare Earth Exchanges® sees standards as an overlooked form of midstream power. A mine can produce an oxide, but standards increasingly determine what that oxide is called, how purity and impurities are measured, how material is traced, what specifications buyers request, and eventually how recycled or lower-carbon material may be differentiated. ISO/TC 298 (opens in a new tab) already covers mine-to-separated-product traceability, separated products through permanent magnets, magnet-scrap analysis and recycling; sustainability standards are also under development.

China's advantage is therefore more subtle than votes. Its enormous operating base supplies the laboratories, production experience, and commercial data from which practical standards naturally emerge. That creates agenda-setting power.

But “Chinese-controlled ISO” would overstate the case. ISO development is consensus-based; participating national members vote, and countries including the United States, Canada, Australia, Japan, and major European economies participate in TC 298.

The West Starts Writing Back

The strongest response is emerging in Europe. European standards bodies created CEN/TC 472 Rare Earth Elements (opens in a new tab), explicitly following ISO/TC 298 across extraction, processing, traceability, recycling, and sustainability. Its first magnet-focused work has already produced CEN/TS 18263:2026 (opens in a new tab), covering recycling-relevant information and labeling for permanent-magnet products—a direct bridge to requirements under Europe's Critical Raw Materials Act.

The United States is catching up institutionally. The American National Standards Institute (ANSI) launched its U.S. ISO Critical Minerals Standards Coordination Group (opens in a new tab)in October 2025 specifically to coordinate American influence across relevant ISO committees. NIST's John Bonevich (opens in a new tab) chairs the U.S. Technical Advisory Group for ISO/TC 298.

Australia has maintained an ISO/TC 298 mirror committee since 2016 and in 2025 adopted—with modifications—the ISO analytical standard for measuring non-rare-earth impurities in rare-earth metals and oxides.

Canada is attacking another layer: measurement and market architecture. Natural Resources Canada supplies rare-earth certified reference materials, while Canada's 2025 G7 presidency drove a roadmap for standards-based critical-mineral markets, emphasizing traceability, interoperable digital credentials, and sustainability criteria.

Japan remains technically formidable but comparatively quiet in rare-earth standards leadership. It participates in ISO/TC 298, operates a sophisticated national certified-reference-material infrastructure through NMIJ, and in 2026 expanded formal standards cooperation with Europe.

REEx Verdict: Standards Are Industrial Policy in Technical Clothing

China currently holds the institutional and industrial advantage, not unilateral control. Europe is building the clearest dedicated counterweight; Washington is organizing belatedly; Canada and Australia are strengthening measurement, traceability, and market standards; Japan remains a technically important participant.

For investors, watch product specifications, analytical methods, traceability, recycled-content rules, and carbon-footprint standards. These can quietly become qualification gates for offtakes, government procurement, and premium markets.

China built much of the rare-earth supply chain. The next contest is over who writes the rules by which that supply chain is measured.
