SMM's assessment for 3 November 2026 puts China's import reference price for 30% tantalum ore at US$240–245/lb, averaging US$242.50/lb. This is down US$1/lb from the previous assessment, according to Shanghai Metals Market (SMM). The modest decline suggests some easing in the assessed market level, although SMM's data do not yet point to a sustained downward trend.
SMM's latest East Africa FOB tantalum ore assessment, dated 29 October 2026, remains at US$4.50–5.00/kg per degree, averaging US$4.75/kg per degree, unchanged from the previous assessment. Prices are quoted in US$/kg per degree, the grade unit reflecting the Ta₂O₅ content of the material. The assessment covers ore grading 28–38% Ta₂O₅, with Rwanda, the Democratic Republic of the Congo and the wider Great Lakes region identified as source locations.
Aterian plc reports that its Rwandan subsidiary, Eastinco Limited, exported 20 metric tonnes of mineral material during October 2026. The figure refers to total mineral material exports and should not be read as tantalum concentrate alone. 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 sourcing, handling and trading activities. The company is also developing relationships with additional Rwandan mines to secure supplies of tantalum- and tungsten-bearing materials. These developments show ongoing commercial activity and the build-out of mineral handling capacity in Rwanda.
Taken together, the latest assessments show a slight weakening in China's CIF tantalum ore price, while the East Africa FOB reference is unchanged. The US$1/lb decline in the Chinese assessment is modest and does not yet establish a trend. Two indicators will be watched in the coming period: whether African suppliers can maintain regular export volumes, and whether Chinese buyers respond to the lower CIF assessment with increased purchasing activity.
