Market evolution: Alkali and rare earth metals (CN 2805) — 2015–2025

Introduction

This report examines the EU's external trade in goods classified under CN 2805 — a broad heading that encompasses alkali and alkaline-earth metals (sodium, calcium, and others), rare-earth metals, scandium, yttrium, and mercury. These materials underpin a wide range of strategic industries, from electronics and batteries to metallurgy and chemical synthesis. Over the 2015–2025 period, the EU's trade position in this product category underwent a profound structural transformation, driven by booming export volumes, a collapse in key supplier relationships, and sharp price dynamics across several sub-segments. The analysis that follows draws on EU trade overview data, partner-level flows, concentration and specialisation metrics, vulnerability indicators, and volatility and shock detection.

1. A structural reversal: the EU flips from net importer to net exporter

The single most striking development over the 2015–2025 window is the EU's transition from a position of net import dependence to one of substantial net export surplus. What was a trade deficit of nearly €35 million in 2015 became a surplus of almost €15 million by 2025.

1.1 Export growth dramatically outpaces import decline

While EU imports in CN 2805 remained broadly stable in value terms (declining only 5.7%, from €50.6 million to €47.7 million), exports surged by 296.7% — from €15.7 million to €62.4 million. The volume story is even more dramatic: export quantities grew by 762.2%, from approximately 1,207 tonnes to over 10,410 tonnes, while import volumes contracted by 21.9% (from 9,179 to 7,166 tonnes). The period saw export values peak at €78.9 million in an intermediate year before settling at €62.4 million in 2025.

1.2 The EU's net import reliance swings to deep export orientation

A key indicator of strategic autonomy is net import reliance, defined as imports minus exports relative to apparent consumption. In 2015, this stood at +46.8%, indicating that the EU relied on external suppliers for nearly half of its consumption. By 2025, the figure had inverted to −65.1%, meaning the EU now exports substantially more than it consumes domestically — a shift of 239 percentage points. Similarly, export propensity rose from 119.0% to 129.8%, confirming that exports have consistently grown faster than domestic output.

1.3 Domestic production shifts toward higher-value output

Behind this trade transformation lies a notable restructuring of EU production. Production volume fell sharply by 66.6%, from 30.0 million kg to 10.0 million kg, yet production value rose by 20.3%, from €50.6 million to €60.9 million. The implied unit value thus tripled — from approximately €1.7/kg to €6.1/kg — strongly suggesting that the EU has moved away from bulk alkali metal production and toward higher-value specialty products. This shift in domestic supply structure both enabled and was reinforced by the export boom.

2. Sodium and specialty alkali metals fuel the export explosion

The aggregate export surge was not evenly distributed across sub-segments. Two product lines — sodium (CN 280511) and the broad category of "other" alkali and alkaline-earth metals (CN 280519) — account for the overwhelming majority of the growth.

2.1 Sodium exports underwent a step-change from 2021 onward

The most spectacular single-segment shift occurred in sodium (CN 280511). Through 2020, annual EU sodium exports ranged between roughly 60 and 280 tonnes, worth at most €600,000. In 2021, volumes jumped to 10,690 tonnes and values to €26.0 million — an approximately fifty-fold increase in volume in a single year. Export levels have since remained in the 9,400–10,900 tonne range, with 2025 values at €22.9 million. The timing coincides with the commercial scaling of sodium-ion battery technology in Europe, for which metallic sodium is a critical precursor. Over the same period, sodium imports collapsed from 1,358 tonnes (€2.5 million) in 2015 to just 169 tonnes (€605,000) in 2025, completing the EU's transformation from a modest net importer to a dominant net exporter of sodium.

2.2 "Other" alkali and alkaline-earth metals show extreme price appreciation

The remaining alkali and alkaline-earth metals category (CN 280519) — which includes lithium, potassium, and other reactive metals — also contributed significantly to the export boom, though through a different mechanism. Export volumes in this segment remained relatively stable (272 tonnes in 2015 versus 312 tonnes in 2025), but values soared from €9.6 million to €33.8 million (+251%). The driver was a tripling of export unit values, from €35,154/t to €107,629/t, reflecting both increased scarcity pricing for critical raw materials (especially lithium, which saw a global price surge in 2022–2023) and possible shifts in the product mix toward higher-purity or more processed forms. Import prices for this same sub-segment were similarly volatile, peaking at an extraordinary €77,725/t in 2022 before retreating to €34,253/t in 2025.

2.3 Mercury trade fades while rare-earth flows remain volatile

At the other end of the spectrum, mercury (CN 280540) — subject to the Minamata Convention's global phase-down — has virtually disappeared from EU trade. Import volumes fell from 52 tonnes to under 1 tonne, and exports from 4 tonnes to 0.3 tonnes. Rare-earth metals (CN 280530), meanwhile, present a more nuanced picture. Import volumes fell from 932 tonnes to 778 tonnes, with values declining from €10.4 million to €11.2 million, while unit prices rose from €11,103/t to €13,901/t — a relatively modest 25% increase compared to the spikes seen in other segments. On the export side, rare-earth volumes and values have been highly volatile (ranging from €0.5 million to €3.5 million), consistent with the EU's still-emerging role as a processor and refiner rather than a primary producer.

3. Geopolitical upheaval reshapes the EU's trade geography

The period 2015–2025 was marked by major geopolitical disruptions — notably the COVID-19 pandemic and Russia's invasion of Ukraine — that left deep imprints on the EU's trade relationships in CN 2805. Import sources consolidated around China, Russia's role collapsed, and the EU's export base diversified rapidly toward Asia and the Americas.

3.1 Russia's near-total exclusion from EU imports

Russian Federation imports underwent the most dramatic collapse among the EU's suppliers. From €8.4 million in 2015 (and a peak of €8.8 million), Russian imports fell to just €777,000 in 2025 — a decline of 90.7%. The contraction accelerated sharply from 2022 onward, directly linked to EU sanctions following Russia's invasion of Ukraine. The high volatility of the Russia trade flow (coefficient of variation of 0.74) reflects this abrupt disruption. The UK also saw steep import declines (−74.4%), likely related to post-Brexit trade reconfiguration rather than sanctions, while US import values fell by 42.8%.

3.2 China remains the indispensable supplier, but at the cost of rising concentration

China's position as the EU's dominant supplier of CN 2805 products proved resilient despite the decade's disruptions. Chinese import values rose by 13.7%, from €27.7 million to €31.5 million. More importantly, as other suppliers exited, China's share of total EU imports in this category increased substantially. The Herfindahl-Hirschman Index (HHI) for import concentration rose by 51.5%, from 3,997 to 6,054 — moving from a moderately concentrated market toward a highly concentrated one. By comparison, the export HHI remained much lower (rising only 14.1%, from 1,721 to 1,964), reflecting a more diversified export base.

A notable price shock occurred in 2022, when Chinese import prices spiked by 161.1% with a shock abnormality score of 6.2 — the most extreme price event in the dataset. This aligns with the global commodity price surge and rare-earth price inflation that followed the post-pandemic recovery and coincided with heightened geopolitical tensions around Taiwan.

3.3 EU exports pivot decisively toward the United States, Asia, and emerging markets

While the import side consolidated around China, the export side witnessed a broad-based geographic diversification. The United States emerged as the EU's single largest export market, with values rising from €2.1 million to €20.7 million (+896.6%). Taiwan saw the most dramatic proportional increase, surging from €299,000 to €12.3 million (+4,004%), while India grew from €1.3 million to €10.0 million (+699.7%). These three markets alone accounted for over €43 million of the EU's €62.4 million in 2025 exports. Japan (+406.6%) and Egypt (+563.1%) also recorded strong growth.

Within the EU, Germany emerged as the dominant exporter, growing from €8.2 million to €35.3 million (+330%). France recorded the most extraordinary transformation, leaping from just €141,000 to €23.0 million (+16,164%), making it the EU's second-largest exporter by 2025. France's high Revealed Comparative Advantage (RCA of 4.23) and specialisation index (RSCA of 0.62) confirm its emerging comparative advantage in this product category, while the Netherlands (RCA of 3.63) also shows strong specialisation — likely linked to its role as a trading hub.

Conclusion

The EU's trade in CN 2805 over 2015–2025 tells a story of dramatic structural transformation. A category that was characterised by net import dependence and modest export volumes at the start of the period has become, by 2025, one in which the EU runs a significant trade surplus. This reversal was driven primarily by the explosive growth of sodium exports — likely connected to Europe's emerging sodium-ion battery value chain — and by strong price appreciation in specialty alkali metals. Simultaneously, domestic production volumes contracted sharply while values rose, signalling a deliberate move up the value chain.

However, this progress carries notable vulnerabilities. The concentration of EU imports has increased markedly as Russia was excluded and other suppliers receded, leaving China as an even more dominant source of supply — a single point of failure underscored by the extreme 2022 price shock. On the export side, the rapid growth of sales to the US, Taiwan, and India exposes the EU to demand-side risks tied to semiconductor cycles, battery industry dynamics, and geopolitical shifts in Asia. The EU's strategic position in alkali and rare-earth metals has undeniably strengthened over the decade, but sustaining and de-risking this position will require continued attention to supply diversification and value-chain resilience.
