The fall in the price of tantalum ingots (Ta≥99.95%) mainly occurred during the phased adjustment period from the fourth quarter of 2025 to the beginning of 2026. Previously, the price was relatively stable or fluctuated slightly, and then rebounded sharply due to supply events (rapidly rising from about 2,800 yuan/kg to more than 5,000 yuan/kg in early 2026). The core driver of the decline is the combination of loose supply and demand margins and changes in downstream purchasing behaviour.
1. Phased recovery and inventory release on the supply side
In 2025, global tantalum ore supply will show marginal improvement:
The expansion of production of lithium-tantalum symbiotic mines such as Greenbushes and Wodgina in Australia, as well as the resumption of production or stable output in some mining areas in Africa, has increased the supply of primary ore.
The secondary resource recycling rate has increased (tantalum recycling from electronic scrap in China accounts for about 6%), further alleviating the shortage of raw materials.
Inventories in the smelting process are relatively sufficient, and some traders are destocking at high levels. In particular, traders are selling tantalum ingots, which directly interferes with the upward momentum of spot prices and leads to a fall in short-term transaction prices.
The actual transaction price of tantalum ingots in the Chinese market fell by about 5%-8% during this period, and the quotations of tantalum oxide and other intermediate products also fell simultaneously.
2. Short-term slowdown in downstream demand and cautious purchasing
Tantalum ingots are mainly used in capacitor-grade tantalum powder, semiconductor sputtering targets, aerospace alloys, etc. Although downstream demand is supported by AI servers, 5G/new energy vehicles, etc., there will be a period of weakness at the end of 2025:
The consumer electronics inventory digestion cycle has been extended, and terminal manufacturers have reduced their stockpiling and turned to cautious replenishment.
Metallurgical tantalum alloy orders stabilised due to delays in some aviation projects.
The enthusiasm for electronic and metallurgical terminal purchases has decreased, and buyers have taken advantage of existing supply channels and relaxed emergency purchases, resulting in weaker demand-side support for prices.
The electronics and metallurgical industries in the Chinese market have reduced their take, which is directly transmitted to the weak demand for tantalum ingots.
3. Adjustment of market expectations and policy impact
Pressure on alternative materials: In some medium and low voltage scenarios, the advancement of alternative technologies such as MLCC ceramic capacitors has put a certain damper on tantalum capacitors.
Rising compliance costs: The US Dodd-Frank Act, EU conflict mineral regulations and other regulations have strengthened due diligence, and traders have increased compliance pressure, prompting destocking behaviour.
Macroeconomic and emotional factors: The overall nonferrous metals market is expected to have loose supply and demand margins during part of 2025, which, combined with the demand for terminal cost control, has inhibited the continued upward movement of tantalum prices.
Internationally, U.S. tantalum prices will remain at US$502/kg in Q4 of 2025, while Chinese prices have retreated to around US$363/kg, reflecting regional demand differences and improved supply availability.
Phased characteristics of price decline
This pullback is not a trend reversal, but the result of short-term rebalancing of supply and demand. The actual transaction price reduction is limited (5%-8%), the supply side is still tight, and the mines remain optimistic about the later period. Although the concept of downstream AI consumption has returned, it is difficult for terminals to quickly accept high prices, resulting in a temporary adjustment. In early 2026, supply disruptions (landslides and production shutdowns) such as the Rubaya mining area in the Democratic Republic of the Congo quickly reversed the situation, causing tantalum ingot prices to rebound rapidly with a significant increase, verifying the "suspension" nature of the decline period.
Enlightenment to the industrial chain
Upstream: Profits of mining and processing companies are under pressure, but large mining companies maintain operations by relying on their scale advantages.
Midstream smelting (such as Oriental Tantalum, etc.): The cost of raw material procurement has dropped, providing space for the expansion of high-purity tantalum powder and target materials, but it is necessary to be wary of recurring geopolitical risks.
Downstream: The cost advantage is prominent, which is conducive to the expansion of applications such as new energy vehicles and AI servers. However, companies tend to lock in long-term contract orders to stabilise the supply chain.
Generally speaking, the decline in tantalum ingot prices is mainly caused by a combination of marginal supply recovery + cautious downstream procurement + destocking behaviour, which is a normal adjustment amid cyclical fluctuations. As a strategic minor metal, tantalum has long been driven by rigid demand for electronics, semiconductors, and new energy. Its price is easily affected by geopolitical and mining incidents. A short-term decline will not change the pattern of tight supply and demand in the medium and long term. It is recommended that industry chain companies pay attention to mining area dynamics, recycling technology upgrades and ESG compliance to cope with future fluctuations.
