Producer
Zhejiang Xinan Chemical Group
Zhejiang Xinan Chemical Group Co., Ltd. (Hangzhou/Kaifeng; SHA: 600596; ~¥12B revenue) is China's largest and the world's largest single producer of glyphosate technical grade. Xinan operates approximately 500,000 metric tonnes per year of glyphosate capacity across its Kaifeng, Henan Province main production base — accounting for roughly 20-25% of global glyphosate output. Xinan uses the IDA (iminodiacetic acid) / glycine-based synthesis route and achieved massive cost advantages through vertical integration into phosphorus chemistry (phosphoric acid, phosphite feedstocks). Listed on Shanghai Stock Exchange; significant state-linked shareholding. Xinan exports heavily to North America, Latin America, and Europe under third-party and white-label arrangements.

Concentration2021
Zhejiang Xinan Chemical Group's Kaifeng, Henan production base is the world's single largest glyphosate facility by capacity — approximately 500,000 MT/year from a single integrated industrial complex. By comparison, Bayer's entire remaining Western hemisphere glyphosate production at Luling, Louisiana is estimated at 50,000-80,000 MT/year. A force majeure event at Xinan's Kaifeng base — flood (Kaifeng sits near the Yellow River flood plain), earthquake, explosion, or regulatory shutdown — would remove approximately 20-25% of global glyphosate technical supply within weeks. There is no Western producer capable of ramping capacity to fill this gap in less than 3-5 years (new glyphosate plant construction requires 2-3 years and significant capital). The Yellow River flood risk is real: Henan Province experienced catastrophic flooding in July 2021 (Zhengzhou flood killed 300+; Kaifeng was affected by downstream flooding). Xinan's Kaifeng complex concentration represents the same single-facility risk profile that Renesas's Naka plant created for automotive semiconductors.
Reuters ↗Origin2023
Zhejiang Xinan Chemical Group became the world's largest glyphosate producer through a combination of state industrial policy, phosphorus chemistry integration, and the specific process chemistry advantage of the IDA (iminodiacetic acid) synthesis route. Xinan's Kaifeng, Henan Province production base grew as China's agrochemical industry developed from the 1980s-2000s — initially supplying Chinese domestic agriculture and then targeting global export markets as Chinese manufacturing costs undercut Western producers. Monsanto had developed glyphosate (Roundup) in 1970 and held patent protection until the late 1990s; when those patents expired globally in the 2000s, Chinese producers like Xinan rapidly scaled production using process chemistry advantages and state-supported capex. Xinan became the dominant global glyphosate supplier at exactly the moment when glyphosate demand exploded with the global adoption of Roundup Ready GMO crops (soybeans, corn, cotton) — crops genetically engineered by Monsanto to tolerate the herbicide. The company that controls the most glyphosate production capacity in the world supplies the chemical without which most of North America's and Latin America's commodity crop acreage cannot be managed economically.
