Zambia has extended the suspension of its 10% export duty on copper concentrates until September 30, 2026. The measure provides additional time for mining companies to reduce growing stockpiles of unprocessed material while key smelting facilities remain under maintenance. The government first introduced the temporary suspension in August 2025.
The duty waiver was introduced to support the mining sector as technical challenges and extended repair programmes at major smelters reduced domestic processing capacity. By allowing exports of copper concentrates without paying the usual duty, the government said it aims to avoid supply bottlenecks and maintain production momentum during the outage period. The latest extension covers a total of 271,742 tonnes of copper concentrates.
Export quotas for copper concentrate under the extended waiver
Zambia allocated export quotas for copper concentrates under the extended duty suspension based on operational needs. The largest allocation was granted to Mopani Copper Mines, which is jointly owned by Abu Dhabi-based International Resources Holding and Zambia’s state mining investment company ZCCM-IH. Mopani received permission to export up to 100,000 tonnes of copper concentrate without incurring the duty.
Other allocations include Lumwana Mining Company, operated by Barrick Mining, with a quota of 56,986 tonnes. First Quantum Minerals received approximately 43,000 tonnes, while Nkana Mining and Minerals Processing was allocated roughly 43,000 tonnes. Lubambe Copper Mine, 70% owned by China’s JCHX Mining, received a quota of 15,000 tonnes.
Konkola Copper Mines, controlled by Vedanta Resources, received an allocation of 12,541 tonnes. The quotas are intended to help producers manage concentrate inventories during a period when processing capacity is returning gradually. Exports under the waiver are designed to provide flexibility until smelter operations normalise.
Smelter maintenance disrupts Zambia’s concentrate-to-cathode processing chain
Zambia traditionally exports most of its copper output as refined copper cathodes rather than raw concentrates. Maintenance programmes and technical difficulties at several smelters have temporarily disrupted the country’s processing chain. As a result, miners have accumulated substantial volumes of concentrate that cannot currently be refined domestically at normal rates.
The export duty waiver is intended to allow producers to access international markets while minimising operational disruptions linked to reduced domestic refining throughput. Industry analysts cited in the source material characterise the policy as a short-term adjustment rather than a permanent shift. Zambia is expected to return to its focus on value-added copper exports once smelter capacity is fully restored.
Zambia targets growth in copper output through 2031 plans
The extension is taking place as Zambia advances plans to expand copper production over the coming decade. Government figures cited in the source material show Zambia exported approximately 890,346 tonnes of copper in 2025. Authorities are targeting annual production of three million tonnes by 2031.
Meeting that target will require continued investment across mining operations, processing infrastructure, exploration programmes and new project development in Zambia’s copper belt. The government’s use of temporary support measures such as the export duty waiver is presented as part of maintaining industry stability while pursuing long-term growth objectives. The extension aligns with efforts to keep production momentum during periods when domestic refining capacity is constrained.
Copper demand drivers and strategic relevance in major markets
The policy extension also reflects copper’s role in sectors where demand is expanding across multiple industries. Copper is described as a cornerstone material for electrical grids and power infrastructure, renewable energy systems, electric vehicles and battery technologies, artificial intelligence data centres, telecommunications networks and advanced manufacturing.
The source material also notes that in the United States copper has been identified as a critical resource for economic resilience, industrial competitiveness and national security. It adds that this has strengthened international interest in major producing regions including Africa. These factors are presented alongside ongoing investment in electrification, clean energy and digital infrastructure.
Zambia maintains its role as a global copper supplier during processing constraints
The decision to extend the export duty suspension is described as supporting mining companies during operational disruptions while safeguarding Zambia’s longer-term production ambitions. Despite temporary processing challenges, Zambia remains one of the most important copper-producing nations globally and a key supplier to international markets. The source material links this position to Zambia’s mineral resources and expanding investment plans.
Zambia’s strategy includes increasing output through continued development activity across mining and related infrastructure. The source material also states that as energy transition efforts, industrial modernization and technological innovation continue to drive consumption higher, Zambia’s ability to maintain production could become increasingly relevant for global supply chains.
