Tanyuan Tech

What Tanyuan Tech does

Tanyuan Tech (碳元科技股份有限公司, Carbon Yuan Technology Co., Ltd.) is a Chinese thermal management solutions company founded in August 2010 and headquartered in Changzhou, Jiangsu Province. The company develops, manufactures, and sells high thermal conductivity graphite heat dissipation materials — including single-layer, composite, and multi-layer graphite films, ultra-thin heat pipes, and vapor chambers (VC) — primarily for consumer electronics OEMs such as Huawei, with applications in smartphones, tablets, laptops, and wearables. Beyond its core thermal materials business, Tanyuan has diversified into glass and ceramic back panels for 5G smartphones, smart home 'Five-Constant' HVAC systems via subsidiary Jiangsu Carbon Yuan Comfort Plus, and EV charging infrastructure.

The company operates a vertically integrated B2B enterprise sales model, selling direct to consumer electronics OEMs without third-party distribution. Manufacturing footprint spans over 87,000 square meters across graphite film workshops (70,346 sqm), heat pipe workshops (9,600 sqm), and office facilities (7,383 sqm) in Changzhou, plus a Vietnam manufacturing subsidiary (Haicheng Technology Vietnam). Revenue is generated through hardware sales to OEM customers on quote-based, multi-year contracts; no public pricing is disclosed. The company holds 65 technical patents in graphite thermal management.

The company has experienced severe financial distress. Originally listed on the Shanghai Stock Exchange main board (stock code 603133) in March 2017 as China's first A-share listed graphite thermal management company, it was delisted from the SSE in June 2024 and now trades on the NEEQ OTC market (stock code 400219) following accumulated losses, going-concern warnings, a controlled subsidiary bankruptcy in July 2023, a Jiangsu CSRC warning letter in April 2023, and administrative supervision measures in July 2024. Multiple senior management and board changes occurred through 2023-2025, and another subsidiary announced temporary production suspension in October 2024.
