What drives China's regional dominance in zinc sulphate production?
Hebei province stands out as China's leading zinc sulphate producing region, with annual output around 100,000 tonnes—roughly one-third of the country's total capacity. This concentration reflects feedstock access, existing sulfuric acid infrastructure, and proximity to downstream agricultural and chemical markets. Nationally, China produces about 300,000 tonnes annually out of a global effective capacity near 800,000 tonnes. The industry remains fragmented, with many small players lacking advanced R&D. Hebei's advantage also ties to integrated chemical clusters, such as Cangzhou Lingang Economic and Technological Development Zone, which supports logistics and by-product synergies. However, environmental compliance costs are rising, pushing consolidation. Larger producers with captive zinc oxide or sulfuric acid supply are better positioned, while smaller firms face margin compression and potential shutdowns, which could tighten supply in the medium term.
