Binh Dien Fertilizer Joint Stock Company is a Vietnam-based agricultural chemical manufacturer primarily engaged in the research, production, and distribution of high-grade compound fertilizers and specialized crop nutrition solutions marketed under its flagship Dau Trau (Head Buffalo) brand. Founded in 1973 and headquartered in Ho Chi Minh City, Vietnam, the company operates as a core subsidiary of the state-owned Vietnam National Chemical Group (Vinachem). The company manufactures and sells a comprehensive portfolio of agricultural inputs, including: custom-formulated and granulated NPK compound fertilizers tailored for specific crops such as rice, coffee, rubber, pepper, sugarcane, tea, fruit orchards, and vegetables; nitrogen-stabilized and loss-reducing fertilizers incorporating Agrotain technology; organic-mineral and bio-organic fertilizers enriched with beneficial microorganisms and humic compounds; micronutrient-fortified (TE) specialty fertilizers; slow-release and controlled-release granular fertilizers; liquid foliar fertilizers and water-soluble fertigation formulas; and specialized soil conditioners engineered to alleviate soil acidity and salinity. Alongside its manufacturing operations, the company provides agricultural technical advisory, soil nutrient testing, crop diagnostic services, and smart farming technical training to agricultural cooperatives and commercial growers. The company maintains an extensive domestic production and distribution footprint through multiple specialized subsidiaries—including Binh Dien Long An, Binh Dien Lam Dong, Binh Dien Quang Tri, Binh Dien MeKong, and Binh Dien Ninh Binh—while actively exporting to international markets such as Cambodia, Laos, Myanmar, and Thailand. In recent developments, the company has accelerated its strategic transition toward climate-resilient and sustainable agriculture by expanding its Smart Rice Farming program in partnership with Vietnam's National Agricultural Extension Center; commercializing new eco-friendly, low-emission, and organic-mineral product lines designed to mitigate greenhouse gas emissions and enhance crop tolerance against climate-induced drought and saltwater intrusion; modernizing regional production facilities with automated, energy-efficient blending systems; and integrating digital QR traceability and smart distribution management systems across its Southeast Asian supply chain network.
