Niobium: Criticality

Why the EU gives niobium a very high risk score

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%	8.9%	1.0%	−$236.7 m	Yes	No mine output since 1959 and 100% import reliant (Brazil 67%, Canada 28%); niobium is on the 2025 US critical list and ferroniobium was a potential stockpile acquisition (136 t) in FY2025 (USGS).
EU	High	0.0%	19.8%	3.1%	−$496.6 m	Yes	100% import reliant; niobium has the second-highest EU supply risk score (4.4, after heavy rare earths), and the Netherlands took 17% of Brazil's 2024 exports (EU CRM 2023; USGS).
India	High	0.0%	5.8%	0.0%	−$172.7 m	Yes	No production; imported 5.8% of world ferroniobium by value in 2024, and niobium is on India's 2023 critical list (UN Comtrade).
China	High	0.0%	38.0%	0.6%	−$1.11 bn	No	Largest buyer, with 38% of world ferroniobium imports in 2024, and 6,500 kt of reserves but only 40 t of output in 2025 (UN Comtrade; USGS).
Japan	High	0.0%	5.9%	0.0%	−$173.6 m	Yes	No production; imported 5.9% of world ferroniobium in 2024 (UN Comtrade).
Latin America	Low	92.4%	0.8%	76.2%	+$2.23 bn	no list	Brazil mined 104,000 t in 2025, 93% of world output, and holds 14,000 kt of reserves (USGS).
Middle East	Low	0.0%	0.2%	0.1%	−$2.88 m	no list	No production; the UAE supplied 5% of US niobium-tantalum concentrate imports in 2021-24 as a trading hub (USGS).
Australia	Low	0.0%	0.1%	0.0%	−$2.12 m	Yes	Supplied 62% of US niobium-tantalum ore and concentrate imports (2021-24), mostly tantalum concentrates with niobium content (USGS).

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 2023 (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.

Niobium has a very high EU supply-risk score of 4.4, with economic importance of 6.5. It is critical in the EU, on the US 2025 list and on India's 2023 list. The EU imports 100% of its processed niobium, and end-of-life recycling contributes nothing. Brazil's near-monopoly is the core risk. Substitutes exist, at a cost in performance or price: vanadium and molybdenum in high-strength low-alloy steels, and molybdenum, tantalum and tungsten in superalloys. The US National Research Council ranked niobium among the most critical minerals (Humphreys).

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). Niobium: supply risk 4.4, economic importance 6.5. EU import reliance, processing 100% EU recycling input rate 0% US net import reliance, 2025 100% share of apparent consumption

Substitutes

Ceramic matrix composites, molybdenum, tantalum and tungsten in superalloys; molybdenum, tantalum and titanium in stainless and high-strength steels; molybdenum and vanadium in HSLA steels, with performance loss or higher cost
