Zambia has extended the suspension of a 10% export duty on copper concentrates until September 30, 2026. The measure targets mining companies dealing with processing bottlenecks linked to ongoing smelter maintenance and other operational constraints. It is intended to help producers reduce unprocessed concentrate stockpiles during periods when domestic processing capacity is limited.
The extension follows repairs and maintenance programs at several of Zambia’s major smelting facilities. Zambia’s approach aims to keep mining operations running with fewer disruptions while smelting capacity remains temporarily constrained. The government said the policy reflects support for the mining sector, which is described as a key contributor to industrial metal supplies.
Smelter maintenance reduces concentrate processing capacity
Copper producers in Zambia have faced reduced processing capacity after technical issues and planned maintenance at multiple major smelters. While the country exports refined copper cathodes, the temporary reduction in smelting capacity has contributed to increasing volumes of copper concentrate that cannot be processed immediately. This situation has affected how quickly miners can move concentrate through domestic facilities.
Authorities introduced the duty-free export measure in August 2025 to prevent operational disruptions and maintain production momentum. Under the scheme, mining companies can ship concentrate to international markets without paying the additional 10% export levy. Government data indicates the exemption covers about 271,742 metric tonnes of copper concentrate.
Export waiver supports production targets and investment plans
The policy is linked to Zambia’s efforts to expand its mining sector and strengthen its position in the global copper market. Copper is described as a key input for electrical infrastructure, renewable energy systems, electric vehicles, battery technologies, and advanced industrial applications. Zambia’s strategy also includes attracting further investment into the sector.
Zambia exported approximately 890,346 metric tonnes of copper in 2025. The country has set a target to increase annual national production to three million tonnes by 2031. Meeting this goal depends on continued investment in mining operations, processing infrastructure, and exploration across the copper belt.
Mopani granted the largest duty-free concentrate quota
Mopani Copper Mines received the largest allocation under the extended export duty waiver. The company is jointly owned by Abu Dhabi-based International Resources Holding and Zambia’s state mining investment firm ZCCM-IH. Mopani has been permitted to export up to 100,000 tonnes of copper concentrate duty-free.
The allocation reflects Mopani’s role within Zambia’s mining sector and its connection to national production growth objectives. Alongside Mopani, other producers received quotas designed to allow concentrate exports during reduced domestic smelting capacity. The quotas are intended to support continuity for companies operating amid smelter downtime.
Other companies receive duty-free export quotas for concentrates
Lumwana Mining Company, operated by Barrick Mining Corp., has been allocated approximately 56,986 tonnes of copper concentrate. First Quantum Minerals and Chinese-owned Nkana Mining and Minerals Processing each received quotas of roughly 43,000 tonnes. Additional allocations include Lubambe Copper Mine, 70% owned by China’s JCHX Mining, with a duty-free quota of 15,000 tonnes.
Konkola Copper Mines, controlled by Vedanta Resources, has been allocated 12,541 tonnes. The distribution of export allowances is described as an effort by the government to balance industry needs while maintaining efficient operations during periods when domestic smelting capacity is reduced. The scheme continues until smelter operations return to normal capacity.
A temporary mechanism while smelters remain offline
The waiver is presented as a temporary solution tied to ongoing smelter maintenance schedules. By allowing producers to export concentrate while smelters are offline, it is intended to help companies maintain cash flow and avoid production slowdowns. It also supports continued investment in future expansion projects.
The policy is also linked to rising global demand for critical raw materials associated with electrification, renewable energy deployment, artificial intelligence infrastructure, and broader industrial development trends. Once maintenance programs are completed and processing facilities return to full operation, Zambia is expected to resume exporting higher-value refined copper products.
Zambia maintains its role in the global copper supply chain
The extension of the export duty suspension is described as reinforcing Zambia’s position as a supplier within the global copper supply chain despite short-term operational challenges. Zambia’s production targets are supported by significant mining investments and major copper resources referenced in government reporting. The country continues positioning itself for demand growth across sectors including renewable energy and electric mobility.
Zambia’s ability to manage temporary disruptions while sustaining output is presented as relevant for both national economic growth and global metal supply security. Copper demand across digital infrastructure and advanced manufacturing is cited as continuing to rise alongside other end-use markets. The policy remains tied to maintaining concentrate flows during periods when domestic processing capacity is constrained.
