China Market: SMM's assessment on 3 November stands at US$240–245/lb, averaging US$242.50/lb, down US$1/lb from the previous assessment. This represents a modest decline in the Chinese import reference price for 30% tantalum ore, suggesting some easing in the assessed market level.
African Market: Aterian plc reports that its Rwandan subsidiary, Eastinco Limited, exported 20 metric tonnes of mineral material during October 2026. Separately, the company agreed to sell 10 metric tonnes of tantalum-bearing concentrate to an investor based in a G7 country in a transaction valued at approximately US$1.8 million. Eastinco's new mineral handling and processing facility in Kigali is now operational, supporting its mineral sourcing, handling and trading activities. The company is also developing relationships with additional Rwandan mines to expand its supply of tantalum- and tungsten-bearing materials. The development is relevant to African tantalum trade because it demonstrates growing commercial activity and the development of mineral handling capacity in Rwanda.
East Africa FOB Tantalum Ore: SMM's latest assessment, dated 29 October, remains at US$4.50–5.00/kg per degree, averaging US$4.75, unchanged from the previous assessment. The assessment covers tantalum ore grading 28–38% Ta₂O₅, with Rwanda, the Democratic Republic of the Congo and the larger great lakes regions identified as source locations.
Market Outlook: The latest assessments show a slight weakening in China's CIF tantalum ore price, while the East Africa FOB reference remains unchanged. The US$1/lb decline in the Chinese assessment is modest and does not yet establish a sustained downward trend. Meanwhile, Aterian's reported October exports and US$1.8 million concentrate sale agreement provide evidence of continued commercial activity in Rwanda. Going forward, the key indicators will be whether African suppliers can maintain regular export volumes and whether Chinese buyers respond to the lower CIF assessment with increased purchasing activity.
