Zhongke Sanhuan Stock (000970): Rare Earth Magnets, Export Controls and What Humanoid Robots Need

Every Tesla Optimus joint motor needs a permanent magnet, and most of the world's high-grade magnets are made in China. Beijing Zhongke Sanhuan (000970) is one of the oldest and largest Chinese makers of neodymium-iron-boron (NdFeB) magnets, which makes it a way to own the most strategic raw material in our Tesla Optimus stocks map. It is also a low-margin industrial company caught in the middle of Beijing's export-control policy, which changed again on November 9, 2026. Here is how the pieces fit.

How Much Magnet Is in a Humanoid?

Estimates from the Foundation for American Innovation, compiled by Humanoid Guide (October 2026). For context, a million humanoids a year at 3 kg each would need about 3,000 tonnes of NdFeB (our estimate), a small fraction of global magnet output today but concentrated in the high-coercivity grades that need dysprosium or terbium. That is why the heavy rare earth rules matter more to robots than the headline tonnage. Optimus specs are in our hardware guide.

China Export Controls: 2025 to 2027

• Apr 4, 2025China requires case-by-case export licenses for seven medium and heavy rare earths (samarium, gadolinium, terbium, dysprosium, lutetium, scandium, yttrium), their compounds and magnets containing them. Still in force.
• 2025Elon Musk says Optimus production was affected by the magnet licensing (Adamas Intelligence).
• Oct 9, 2025Beijing expands controls to more elements and adds extraterritorial rules covering foreign-made products with Chinese-origin rare earths or technology.
• Nov 2025After the Trump-Xi meeting, the October 2025 measures are suspended for one year, to November 10, 2026.
• Nov 9, 2026MOFCOM Announcement No. 58 extends six suspensions to January 10, 2027, ahead of an expected Trump-Xi meeting at APEC (Rare Earth Exchanges).

Why Controls Cut Both Ways for Sanhuan

Export controls make Chinese magnets more strategic, but Zhongke Sanhuan is the exporter that has to apply for the licenses. In the first half of 2026, overseas sales were about RMB 2.0 billion, or 55% of revenue, mostly billed in dollars and euros. Slow licenses or a return of the October rules would hit those sales first, while competitors outside China, such as MP Materials in Texas, gain from Western buyers diversifying. On the other hand, a tight market for licensed, high-grade magnets can support prices for approved Chinese suppliers. Investors are effectively taking a view on trade policy.

H1 2026: Sales Up, Margins Thin

Source: Shanghai Securities News via 10jqka (August 2026). Q2 revenue rose 32.6% to RMB 1.94 billion. Net financial expenses jumped to about RMB 83 million, mostly currency losses. For full-year 2025, revenue was RMB 6.64 billion (-1.6%) and net profit RMB 91.3 million, up 660% from a very low 2024 base. We could not verify Q3 2026 figures at the time of writing; we will update this page when they are confirmed.

The Humanoid Robot Angle

In its 2026 interim report, the company said it is developing high-performance magnets for humanoid robots to be ready when the technology commercializes, and is also watching the low-altitude (drone and eVTOL) economy. It gave no customer names, volumes or revenue. Joint motors made by actuator suppliers such as Tuopu and motor makers such as Nidec would be the direct buyers of its magnets, not Tesla itself. A robot boom therefore helps Sanhuan indirectly and only at the volumes in our Optimus production timeline.

Valuation and Risks

At about CNY 13 billion, the stock trades near 1.8 times trailing sales but over 100 times trailing earnings (our estimate from StockAnalysis data). The forward P/E of about 56 assumes profits roughly double. The shares sat near their 52-week low in late September.

• Policy: license delays, the January 2027 deadline and possible new rules.
• Raw material prices: NdPr and dysprosium price swings feed straight into margins.
• Competition: larger Chinese rivals and new US and Japanese capacity.
• Currency: 55% overseas sales means yuan strength hurts reported profit.

FAQ: Zhongke Sanhuan Stock

The Bottom Line

Zhongke Sanhuan sells the material every humanoid joint depends on, and China's control over that material is now a bargaining chip in US-China talks. That makes the stock a policy and commodity play more than a robot play: sales are growing, profit is thin, robot revenue is not disclosed and the latest export-control reprieve runs only to January 10, 2027. Watch the license regime and rare earth prices first, humanoid volumes second.
