About Us


Guizhou Chanhen Chemical Corporation (hereinafter referred to as: Chanhen), is a government-recognized High-tech private company, mainly engaging in phosphate ores mining and beneficiation as well as the intensive processing of phosphorus products. The production bases are located in Fuquan City of Guizhou Province, Shifang City of Sichuan Province and Fusui County of Guangxi Zhuang Autonomous Region. Its phosphate mines are located in the Weng’an and Fuquan of Guizhou Province. The company has a registered capital of RMB 542 million, with phosphate ore production capacity of approximately 2.5 million tons per year; about 600,000 tons/year of phosphate-related products are sold globally, generating an annual sales revenue of over RMB 4.3 billion. Chanhen is committed to promoting the continuous development of the industry through scientific and technological innovation, and has been awarded as "National High-tech Enterprise", "Top 10 in China's Phosphorus Chemical Industry", "National Grade Green Factory '". It has been listed on the Shenzhen Stock Exchange since 2017.

Innovation is the soul and core competitiveness of Chanhen. After long-term research with unremitting efforts, Chanhen has formed a product cluster with multiple functions, high quality and outstanding comprehensive competitiveness. The best-selling product, Monocalcium Phosphate (MCP) Feed Grade, has dominated domestic market since 2005; its global market share reaches 20%, representing the highest technology level in Asia Pacific region. Fire protection Monoammonium Phosphate(MAP) fills the blank market for ABC Dry Powder in China, which requires high performance raw materials of MAP.

Making excellence in the product quality is our motto. Chanhen has participated in the formulation of national and industry standards for Monocalcium Phosphate, Monoammonium Phosphate, Ammonium Polyphosphate and group standards for phosphogypsum pretreatment technical specifications.

Relying on domestic scientific research institutes, Chanhen has built its own engineering and technology research institute and has a strong R&D system. Many research achievements we made have filled in the technical gaps at home and abroad. In 2013, the hemi-hydrate wet-process phosphoric acid technology was identified as "international advanced level" by  China Petroleum and Chemical Industry Federation; in 2019, the hemi-hydrate phosphogypsum modified cementitious material and filling technology were identified as "international leading level", which solves two major industrial problems: phosphate industry-gypsum stockpiling pollution and geological disasters by ore mining.

Faced with new challenges and opportunities, Chanhen team focuses on integrated development based on phosphorus and fluorine resources, stepping into new energy battery materials field to build a circular business.

The first phase of the New Mining and Chemical-Manufacturing Integrated New Energy Material Circular Industry project located in Fuquan and the project of hemi-dihydrate Wet-processed Phosphoric Acid and Deep Processing in Fusui, Guangxi are both built completely and put into operation. And the New Mining and Chemical-Manufacturing Integrated New Energy Material Circular Industry project located in Weng’an is under construction. After the completion of the three projects, Chanhen will hold larger capacity of phosphate concentrate, more products such as wet-processed Merchant Grade Phosphoric acid, Ferric Phosphate, wet-processed purified Phosphoric Acid, and Ammonium Sulfate etc. Based on feed phosphate, firefighting phosphate, and fertilizer phosphate, a new industrial cluster is being formed, which is actively developing towards Merchant Grade Phosphoric Acid, purified Phosphoric Acid and battery materials such as Iron Phosphate.

Focusing on ambitious goals, Chanhen team is chasing the dream of "the Phosphorus Chemical Industry is better because of us", using our diligence and wisdom to build "a bridge between phosphorus, fluorine elements and a better life".
