Disruptions to shipping routes and the Strait of Hormuz are tightening sulfuric acid supplies. The Middle East accounts for about 24% of global sulfur output, with nearly 40% of seaborne sulfur passing through Hormuz. Chile’s main suppliers—China, Peru and South Korea—are affected, pushing spot prices up nearly 20% since early 2026. Chile is advancing domestic smelter projects to reduce import reliance and secure supply.
