Highlights
- China published national standard GB/T 34500.7-2026 on May 25, effective December 1, 2026, establishing ICP-MS testing for thorium and uranium in rare earth processing waste and wastewater.
- The standard was led by Jiangxi's provincial rare earth quality inspection center and co-developed by Ganzhou Qiandong, Baotou Research Institute of Rare Earths, and Fujian Golden Dragon Rare Earth.
- Standardized measurement of radioactive byproducts is a prerequisite for environmental regulation, waste management, and value recovery in rare earth processing.
- Western nations building rare earth supply chains must develop not only processing plants but also laboratories, waste systems, and regulatory standards to compete with China's integrated approach.
China has established a national method for measuring radioactive thorium and uranium in rare earth processing waste and wastewater, closing what Chinese authorities describe as a gap in national standards. The new national standard (GB/T 34500.7-2026) uses inductively coupled plasma mass spectrometry (ICP-MS) and takes effect December 1, 2026. It sounds technical—and it is—but controlling radioactive waste is one of the less glamorous barriers to building a competitive rare earth industry. China is standardizing that problem while the West is still rebuilding much of its processing infrastructure.
REEx Insight: The Uncomfortable Chemistry Behind the Magnet
Rare earth independence requires more than mines, separators, and magnets. It requires dealing economically and safely with everything that comes out the other end.
Thorium and uranium can accompany rare earth-bearing minerals, creating waste-management, permitting, and environmental challenges. China's new standard does not solve that problem. It does something more basic but important: it establishes a common measurement framework.
For Great Powers Era 2.0, the lesson is straightforward. Western governments seeking Chinese-independent supply chains must build not only processing plants, but laboratories, standards, waste systems, and regulatory expertise around them.
Jiangxi Puts a Ruler on Radioactive Waste
China's official standards database confirms that GB/T 34500.7-2026 was published May 25 and becomes effective December 1. The recommended national standard establishes ICP-MS testing for thorium and uranium in rare earth residues and wastewater.
The Jiangxi Provincial Tungsten and Rare Earth Product Quality Supervision and Inspection Center led its development, joined by organizations including Ganzhou Qiandong Rare Earth Group, Baotou Research Institute of Rare Earths, Fujian Golden Dragon Rare Earth, and Hunan Rare Earth Metal Materials Research Institute.
The reported technical advance is not a new separation process. Rather, developers say standardized sample preparation, calibration, and interference removal should improve detection of trace thorium and uranium and make results more comparable across production, recycling, environmental monitoring, and waste disposal.
That distinction matters. Better measurement does not equal safer waste management. But you cannot reliably regulate—or recover value from—what you cannot consistently measure.

|---|---|---|---|---|
| Jiangxi Provincial Tungsten and Rare Earth Research Institute | Government-linked research, testing, and standards institution — Jiangxi Province | Conducts testing, analytical research, and quality supervision for tungsten and rare earth products. Its associated provincial quality-supervision center operates in Ganzhou, the heartland of China's southern ionic-clay rare earth industry. | Represents the often-overlooked measurement and compliance infrastructure supporting China's rare earth ecosystem—particularly important for environmental control of thorium, uranium, and processing waste. | Lead drafting organization for the new ICP-MS testing standard. Its participation in other national rare earth standards confirms a continuing standards-development role. |
| Ganzhou Qiandong Rare Earth Group Co., Ltd. (opens in a new tab) | Integrated private rare earth group — Ganzhou, Jiangxi | Founded in 1988; operates across rare earth basic materials, functional materials, downstream products, recycling, and processing equipment. The company reports more than 2,000 employees and a substantial network of subsidiaries. | An important industrial participant because it connects the standard-setting process with companies that actually process rare earth materials. Qiandong has repeatedly participated in drafting Chinese rare earth standards. | Co-developer, bringing commercial processing and analytical experience to the standard. |
| Baotou Research Institute of Rare Earths (BRIRE) | Major rare earth R&D institute — Baotou, Inner Mongolia | One of China's core rare earth research institutions, deeply involved in metallurgy, materials, analytical methods, and industry standards. | Baotou is China's great light-rare-earth industrial cluster. BRIRE's repeated appearance in national standards demonstrates how China links laboratory expertise, industrial producers, and national standardization. | Co-developer, contributing analytical and rare earth processing expertise. |
| Fujian Golden Dragon Rare Earth Co., Ltd. | Integrated producer; controlled by Xiamen Tungsten — Changting, Fujian | Produces rare earth oxides, metals and alloys, magnetic materials, and other functional materials. Reported capacity includes 20,000 tonnes/year of NdFeB magnetic materials, alongside oxide and metal production and recycling operations. | Particularly notable because Golden Dragon stretches well downstream toward permanent magnets. Xiamen Tungsten holds 65.2%, while Fujian's state-owned-assets authority is identified as the ultimate controller. | Co-developer, providing a downstream industrial perspective on waste testing and environmental compliance. |
| National Rare Earth Standardization Technical Committee (SAC/TC229) | National standards committee — China | Coordinates Chinese national standardization across rare earth materials, analytical methods, alloys, and related products. | This is the strategic layer. TC229 helps convert Chinese industrial practice into formal technical standards. Its repeated jurisdiction over rare earth standards gives China institutional influence extending beyond simply producing the world's rare earth materials. |

Although the national standard and participating organizations can be independently confirmed through China's official national standards database, technical performance claims should be independently validated before investment or commercial reliance.
