China has decided to limit fertilizer exports to protect its domestic market as global supply chains face severe disruption due to the ongoing war involving the United States, Israel, and Iran. According to industry sources cited by Reuters, Beijing banned exports of nitrogen-potassium compound and certain phosphate fertilizers in mid-March 2026. With earlier restrictions on urea and export quotas still in place, only a few types of fertilizers, mainly ammonium sulfate, are currently being exported. Reuters estimated that China’s fertilizer exports have now fallen to between half and three-quarters of last year’s volume, potentially reducing shipments by up to 40 million metric tons.

China, one of the world’s largest fertilizer exporters, sold over 13 billion dollars’ worth of fertilizers last year. The new restrictions come as fertilizer transport through the Strait of Hormuz has nearly halted, affecting about one-third of global shipments. Analysts noted that China tends to restrict exports during global crises to prioritize food security and shield its domestic market from price shocks.
