Tantalum: Criticality

How conflict and artisanal mining make tantalum critical

What this tab covers How exposed economies are to a supply disruption: the EU, US and India listings, the concentration score, and a quantified exposure for the US, EU, India, China, Japan, Latin America, the Middle East and Australia. Where the EU scored it, a chart of supply risk against economic importance, with import reliance, recycling input and substitutes.

Exposure by region

Region	Exposure	Share of world output	Share of world imports	Share of world exports	Net trade (US$)	On own critical list	Position
US	High	0.0%	25.7%	29.2%	−$13.8 m	Yes	No mine output since 1959 and 100% net import reliance; apparent consumption rose 58% to 890 t in 2025, and the DLA is buying ingot for the stockpile (USGS 2026).
EU	High	0.0%	7.5%	5.1%	−$28.3 m	Yes	Critical (not strategic), 99% import reliant at the mining stage with a 1% end-of-life recycling input rate, and covered by the Conflict Minerals Regulation (EU CRM 2023).
India	Low	0.0%	0.3%	0.1%	−$1.38 m	Yes	No production and negligible trade ($2.4 million of imports in 2024); on India's 2023 critical list (Comtrade).
China	Low	3.6%	8.7%	30.4%	+$145.2 m	No	Mines 80 t but holds 240,000 t of reserves and is the largest processor and exporter (30.4% of HS 8103 exports by value in 2024) (USGS; Comtrade).
Japan	Low	0.0%	7.6%	10.9%	+$12.2 m	Yes	No mining but a major processor and exporter (10.9% of HS 8103 exports) and importer (7.6%) in 2024 (Comtrade).
Latin America	Medium	14.6%	2.2%	0.1%	−$18.8 m	no list	Brazil mined 190 t in 2025 (8% of world) with 40,000 t of reserves; Bolivia 2 t (USGS 2026).
Middle East	High	0.0%	2.1%	0.2%	−$16.4 m	no list	No mining; the UAE supplied 5% of US ore imports in 2021-24, mainly as a transit hub (USGS 2026).
Australia	Low	2.5%	0.7%	0.1%	−$5.47 m	Yes	Mined 50 t in 2025 but holds 120,000 t of reserves, after supplying perhaps 60% of the world from Wodgina and Greenbushes in the mid-2000s (USGS 2026; MMTA 2016).

Exposure rating: High when the region is a net importer whose import share is at least three times its share of world output (or, for farm goods, it produces under 70% of what it consumes); Medium for other net importers (or 70-95% self-sufficiency), raised to High when world supply is highly concentrated in another country; Low for net exporters or self-sufficient regions. Net importer status uses tonnage where reported, otherwise value. Output: World Mining Data, 2024. Trade: UN Comtrade 2024 (EU = sum of member states, including intra-EU trade). Critical lists: US 2025, EU 2024/1252, India 2023, China 2016 strategic minerals, Japan METI, Australia 2024.

The EU rates tantalum critical, with supply risk 1.3, economic importance 4.8 and 99% import reliance, but not strategic. It is on the US 2025 and India 2023 lists. Risk comes from geography and governance: about 60% of mine output is from DR Congo and Rwanda, where conflict and artisanal mining persist. Substitutes exist, but with performance loss or higher cost. Aluminium, ceramics and niobium can replace it in capacitors, and niobium or tungsten in carbides.

EU 2023 assessment

Chart: EU 2023 criticality: supply risk against economic importance

Each dot is a material assessed by the EU in 2023. The shaded corner is the critical zone (supply risk ≥ 1.0, economic importance ≥ 2.8). Tantalum: supply risk 1.3, economic importance 4.8. EU import reliance, extraction 99% EU recycling input rate 1% US net import reliance, 2025 100% share of apparent consumption

Substitutes

Niobium and tungsten in carbides; aluminium, ceramics and niobium in capacitors; various metals in corrosion and high-temperature uses, with performance loss or higher cost
