Zambia has extended its 10% copper concentrate export duty suspension until September 30. The temporary waiver aims to prevent severe supply bottlenecks as the nation’s major domestic smelters undergo prolonged maintenance and repairs.
The tax exemption permits a total of 271,742 metric tons of raw copper concentrate to be shipped abroad. The strategy marks a brief departure from Zambia’s traditional model of exporting fully processed, refined cathodes.
Abu Dhabi-backed Mopani Copper Mines holds the largest duty-free quota at 100,000 tons. Meanwhile, Barrick Gold’s Lumwana operation was granted 56,986 tons, followed by First Quantum Minerals with approximately 43,000 tons.
The ongoing outages come at a critical time for Africa’s second-largest copper producer. The state recently reported 2025 exports of 890,346 tons while maintaining a long-term strategy to hit 3 million tons annually by 2031.
A simultaneous 60-day shutdown began at Vedanta’s Konkola Copper Mines Nchanga plant. Executives noted the deep maintenance window is crucial to “enhance operational efficiency, reliability, and long-term production performance” across aging domestic facilities.
Global supply constraints are magnifying the impact of these domestic infrastructure delays. Analysts warn the closures could heavily restrict copper and critical industrial chemical production while regional conflicts strain standard supply chains.
The extended tax relief ensures local mining corporations avoid severe inventory pileups. This targeted intervention helps guarantee consistent export revenues and protects operating capital until local processing plants resume full operations this fall.
