According to recent SMM on-site surveys, sulphur and sulphuric acid supply in Zambia and the DRC has not experienced significant shortages, and has not yet had a substantive impact on copper and cobalt smelting production in the two regions. Zambia's domestic sulphuric acid supply is self-sufficient, with supply pressure concentrated in the DRC. Currently, raw materials in the DRC can be procured normally, but prices fluctuate at high levels, with the delivery-to-factory price of sulphuric acid ranging from $1,000 to $1,400/mt, reaching a peak of $1,400/mt. Sulphur DAP quotes range from $1,500 to $1,800/mt, and DDP quotes range from $2,300 to $2,500/mt. Dar es Salaam port holds sulphur inventory, mostly held by traders holding back from selling while waiting for higher prices.
