Baotou Tianhe Magnetics Technology Co., Ltd.
Sintered NdFeB and sintered SmCo rare-earth permanent magnets, including in-house strip-casting of magnet alloy and, per the company's own materials, in-house design and manufacture of its own magnet-production equipment. One of a small number of Chinese magnet makers producing SmCo alongside NdFeB. Reported end markets include new-energy vehicles, wind power, and other high-performance motor applications.
At a glance
- Founded
- 2008 — Incorporated in Baotou, Inner Mongolia on May 22, 2008, per Shanghai Stock Exchange registration data. The company's own site traces its lineage to a predecessor, Taiyuan Connector Factory, founded in 1988, which it says entered rare-earth magnet production in 1993 before the Baotou entity was formally established in 2008. A third-party industry listing gives 2000 as the founding year; this is unverified and inconsistent with the exchange registration date.
- Headquarters
- Baotou, Inner Mongolia Autonomous Region, China, with a second production site in Tianjin and sales or representative offices in Japan, the United States, and Germany
- Ownership
- Publicly listed on the Shanghai Stock Exchange Main Board (ticker 603072, listed January 3, 2025). Controlling shareholder is Tianjin Tianhe Yingya Technology Co., Ltd. (approximately 34% stake). Individual actual controllers disclosed as Yuan Wenjie, Yuan Bo, and Yuan Yi.
- Revenue
- CNY 2.590 billion
Reported, FY2024.
A separately reported figure describing overseas revenue of over CNY 1.2 billion (about 48% of total income) in an earlier year is broadly consistent in magnitude but was not cross-verified against this figure line by line.

Narrative
Baotou Tianhe Magnetics Technology Co., Ltd. is a Chinese rare-earth permanent-magnet producer headquartered in Baotou, Inner Mongolia, with a second production site in Tianjin and sales or representative offices in Japan, the United States, and Germany. The company was incorporated in 2008 and traces its history further back to a 1988 predecessor company that it says entered rare-earth magnet production in 1993. It listed on the Shanghai Stock Exchange Main Board (603072) on January 3, 2025. Its core business is sintered NdFeB magnets, with a stated design capacity of 12,500 tons per year and reported actual output of approximately 6,184 tons in 2024; it also produces sintered SmCo magnets at a stated 500 tons per year. In October 2025 the company announced a roughly CNY 900 million investment in a new Inner Mongolia R&D and production base, with phase-1 construction slated to begin in March 2026 over an approximately 18-month build. For fiscal year 2024 the company reported consolidated revenue of about CNY 2.59 billion and net profit of about CNY 136 million, both down year over year.
Where public sources disagree
- Founding year is disputed across sources: the company's own site frames its history as continuous from a 1988 predecessor entering rare-earth magnets in 1993, the Shanghai Stock Exchange registration record gives an incorporation date of May 22, 2008 for the current legal entity, and a third-party industry listing states 2000 with no supporting detail.
- The claim that Baotou Tianhe builds its own magnet-making equipment and does in-house strip-casting is stated on the company's own website but was not independently corroborated by a third-party source.
- No independent public source was found breaking down SmCo actual output (as opposed to the stated 500 t/yr capacity), or confirming that Baotou Tianhe is "one of the few" Chinese majors with SmCo at scale — this characterization appears in the company's own material, not in third-party industry coverage located during research.

How this page is sourced
Everything here comes from public sources — company filings, annual reports, exchange announcements, government releases and trade press. Every figure is linked to the document it came from and carries the date that document was published, because a capacity number without a date is not a fact, it is a rumor with a decimal point.
What is deliberately absent: material nonpublic information. I have spent more than two decades in this industry and a good deal of what I know about these companies I learned under NDA. Those obligations do not expire and they do not bend for a website. Nothing I have been told in confidence appears here in any form, and nothing on this page — or missing from it — should be read as a signal about what I know privately. I hold NDAs absolutely. It is the reason clients tell me things.
Judgment is the other thing left out on purpose. This page reports what has been published and who published it. Whether a target is credible, whether a ramp will hold, whether a capacity figure survives contact with the plant behind it — that is the work I do for clients, and it does not belong in a free reference page.
Where public sources disagree, I say so rather than picking a winner. Where a figure has not been published, the field says so rather than carrying an estimate. An empty field is information too.
Public filings tell you what a company has said. Whether it holds up is a different question, and the one I get hired to answer.
