Zambia has authorized two major copper producers to resume the export of sulphuric acid to the Democratic Republic of Congo.
Commerce Minister Chipoka Mulenga confirmed that Chambishi Copper Smelter and Mopani Copper Mines can now ship limited quantities across the border.
The decision eases a previous export ban triggered by domestic shortages and global supply disruptions linked to the ongoing war in Iran.
Sulphuric acid is a critical byproduct of the smelting process used extensively in the extraction of copper and cobalt from ores.
As Africa’s second-largest copper producer, Zambia typically generates two million metric tons of the acid annually to support regional mining operations.
Miners in the Congo, the world’s leading cobalt producer, had previously considered cutting output due to the tightening supply of chemicals.
The government noted that local stocks have recovered sufficiently to allow these exports without jeopardizing the stability of the domestic market.
A third party, chemicals trader Alliswell Investment Limited, has also received authorization to transport approximately 5,000 metric tons of the acid.
Mopani Copper Mines is expected to supply Glencore, while Chambishi will facilitate exports through three Chinese-operated mines located in the Congo.
While export permissions could widen if conditions improve, the government remains cautious as major smelters plan maintenance shutdowns later this year.
This strategic resumption of trade reflects a stabilizing supply chain within the central African copperbelt despite persistent regional geopolitical pressures.
