China's reported sulphuric acid export ban threatens global supply chains

China has reportedly imposed a ban on sulphuric acid exports effective May, causing alarm among foreign buyers. The chemical is essential for fertilizer and battery production. This follows a supply squeeze from the Gulf conflict, where shipments from the region (25% of global production) stalled since military strikes began on February 28. China accounted for 45% of nearly 10 million tonnes shipped from Asia last year and about 23% of global exports. Analysts warn of significant implications for global supply and prices, noting China has become a linchpin in sulphuric acid trade. In 2024, China's sulphuric acid exports totaled US$349 million, with top destinations including Chile, Indonesia, Saudi Arabia, Morocco, India, and the United States.
