Hanfeng is a leading developer and producer of slow and controlled release (S&CR) fertilizer in China and South East Asia. Headquartered in Toronto, Canada, Hanfeng owns production facilities in Jiangsu, Heilongjiang, Shandong, and Shangxi China. Hanfeng also has a R&D centre in Shanghai and is currently constructing a new facility in Indonesia with a joint venture partner. Hanfeng's production primarily targets the large agricultural market in and the urban greening market in China and SE Asia.

While China is the world's largest consumer and producer of conventional fertilizers, its S&CR fertilizer industry is still at an early stage of development. China's domestic fertilizer industry is fragmented with numerous small regional producers, many operating out-dated and inefficient equipment. There is very little domestic production of S&CR fertilizers and high quality NPK fertilizers. Imported S&CR fertilizers are too expensive to penetrate the China market to any significant extent. The government of China and the agricultural industry has increasingly stressed the importance of S&CR fertilizers as a key component for improving crop yields, farm incomes and raw material efficiency and reducing water pollution.
