The tantalum market at present is showing an unprecedented sharp surge in prices. The latest China CIF price of tantalum concentrate has reached $180–190 per pound, recording a dramatic increase of 135% compared to the level before the Chinese Spring Festival. This dramatic price fluctuation is the result of two major factors becoming intricately intertwined: sudden supply disruptions and a rapid supply-demand mismatch within the distribution chain.
Background of the Price Surge
1. Severe Supply Disruption in Africa (Accident at Major Mines)
In February 2026, large-scale landslides and collapse accidents occurred at mines such as the Rubaya mine in eastern Democratic Republic of Congo (DRC), which is one of the world’s major production areas of tantalum.
As a result, the route through which supplies are delivered to the global market via Rwanda and other countries suddenly became dysfunctional, triggering severe supply tightness in the spot market.

2. Explosion of Demand for Tantalum Capacitors Due to the AI Boom
The rapid expansion of AI servers and data centers is strongly driving demand for tantalum.
Advanced electronic equipment such as AI servers requires “tantalum capacitors (especially tantalum polymer capacitors)”, which possess high reliability, stability, and excellent surge resistance.
In response to this demand increase, major capacitor manufacturers such as KEMET (under Yageo) and Panasonic have successively implemented significant price increases since the latter half of 2025.
3. Increasing Demand from 5G, EV, and the Defense/Aerospace Industries
Demand continues to expand due to infrastructure development for next-generation communication standards (5G) and demand related to battery management systems (BMS) for electric vehicles (EVs).
Furthermore, amid rising geopolitical risks such as the situation in the Middle East, defense budgets are increasing in many countries, leading to a sharp rise in demand for materials essential for aerospace alloys and military/defense systems.
4. Strategic Stockpiling and “Stockpiling Purchases” in Supply Chains
Tantalum has been designated as a “critical mineral” in the United States and the European Union.
In addition to strategic stockpiling movements by organizations such as the U.S. Defense Logistics Agency (DLA), downstream electronic component manufacturers and traders—anticipating news of supply instability and price rises in Congo—have moved to increase their inventories (rush buying).
This has further widened the supply-demand gap.
5. Trends in the Chinese Market
In China, supported by the strong trend in raw material prices, prices of downstream tantalum products are also gradually entering an upward trend. The following developments have been confirmed:
- Tantalum oxide (99.5%): The trading price in the Chinese market has reached 3,900 yuan/kg, and manufacturers have implemented a slight price increase compared to the pre-holiday price on a month-on-month basis.
- Tantalum ingot (99.95%): Currently traded at 5,500 yuan/kg, while some manufacturers are proposing price increases to 6,000 yuan/kg.
However, regarding ingots, the increase since before the Spring Festival has been relatively small.
This is because some traders moved to dispose of (take profits on) the tantalum ingots they held, which hindered the rise of spot prices and temporarily slowed the upward momentum of ingot prices.
Future Market Outlook and Importance of Secondary Resources
The selling by some traders is limited and short-term. Supported by the strong cost pressure caused by the surge in tantalum ore prices, downstream procurement demand is expected to recover quickly.
It is considered unlikely that the medium-term upward trend supported by AI demand will change due to this short-term disruption, and tantalum ingot prices are expected to soon catch up with the pace of raw material price increases.
For the time being, the strong performance of the overall tantalum market is expected to continue. At the same time, such supply shocks and sharp price fluctuations in primary resources have highlighted the risk of dependence on specific countries or regions.
Toward building a long-term and stable procurement network, the importance of recycled raw materials recovered from urban mines—such as cemented carbide tool scrap and used electronic components—has entered a phase where it will likely be re-evaluated within the industry even further in the future.
