Copper king Chile faces acid supply crunch as China exports dry up

China's sulphuric acid exports to Chile fell to zero in March, tightening supply for the world's top copper producer. The shortage matters because sulphuric acid is used to produce roughly half of Chile's refined copper, potentially pressuring copper output and related supply chains. The development is negative for Chilean copper producers and points to a trade-linked raw materials bottleneck.
