Market evolution: Fluorine complex salts (CN 2826) — 2015–2025

Introduction

CN 2826 covers a broad family of fluorine-based inorganic chemicals — fluorides, fluorosilicates, fluoroaluminates, and other complex fluorine salts — that serve as critical inputs for the aluminium smelting, chemical, pharmaceutical, and increasingly the battery and electronics industries. Over the period 2015–2025, the EU's trade in these products underwent a dramatic transformation. A once-comfortable trade surplus was eroded to near-zero, with a severe import-driven deficit in 2022–2023 marking the most acute phase. By 2025, a partial recovery was underway, yet the structural features of the market — rising import dependence on China, declining domestic production volumes, and heightened price volatility — point to lasting vulnerabilities. This report examines the main dynamics behind these shifts, organised around the trade balance crisis, the geographic reorientation of partners, and the structural changes in production and pricing across product segments.

Overview of CN 2826 trade

1. From Surplus to Crisis and Back: The Dramatic Swing in the EU's Trade Balance

The EU began the period as a net exporter and ended it barely in surplus

In 2015, EU exports of CN 2826 stood at €90.9 million, comfortably exceeding imports of €47.9 million and generating a trade surplus of €43.0 million. By 2025, exports had risen to €125.0 million (+37.6%) while imports had more than doubled to €120.8 million (+152.0%), compressing the surplus to just €4.2 million — a 90.2% decline. The overall trade data reveal a clear structural erosion of the EU's net competitive position in this market.

The 2022–2023 crisis was overwhelmingly price-driven

The most striking feature of the decade is the import spike of 2022–2023. Total import value peaked at €184.5 million in 2022 — nearly four times the 2015 level — while import volumes reached only 42,008 tonnes at their maximum (in 2018), a far more modest increase. The import unit price surged to a peak of €4,800 per tonne in 2022, up from €1,527 per tonne in 2015 and a trough of €1,346 per tonne in 2017. This confirms that the crisis was driven almost entirely by escalating unit prices rather than a physical shortage of supply. The European energy crisis of 2021–2022, which struck energy-intensive chemical production particularly hard, was a primary factor: with domestic fluorine output contracting, EU buyers were forced onto the import market at a time of global price inflation.

The net import reliance metric captures the full arc of vulnerability

The net import reliance indicator traces the complete cycle. The EU began as a net exporter (−7.6% in 2015), swung to heavy net import reliance peaking at 22.8% — presumably during 2022 — and returned to slight net-export status (−2.7%) by 2025. Meanwhile, trade intensity rose from 30.7% to 42.1% and export propensity from 21.0% to 27.6%. These rising ratios indicate that the EU's fluorine salt sector has become structurally more open to international trade — and therefore more exposed to external shocks — than it was at the start of the period.

2. Geographic Reorientation: China's Consolidation and Russia's Collapse

China became the overwhelmingly dominant source of EU fluorine salt imports

China's share of EU imports grew from €26.6 million in 2015 to €70.7 million in 2025 (+165.2%), peaking at €125.9 million in the crisis year of 2022. This makes China by far the largest import partner, accounting for well over half of EU import value. The next-largest partner, Tunisia, reached only €4.9 million in 2025. Chinese supply proved remarkably stable in volume terms (coefficient of variation of just 0.10, the lowest among the top import partners), meaning that the EU's growing reliance on China was not characterised by erratic supply flows but rather by steadily rising prices during the crisis period.

EU export markets were fundamentally reshaped by geopolitical forces

The EU's export geography was profoundly reoriented. Exports to Russia collapsed from €10.6 million in 2015 to just €0.3 million in 2025 (−97.2%), reflecting the impact of EU sanctions following the invasion of Ukraine. Russia had been the second-largest export market in 2015; by 2025 it was marginal. In contrast, exports to the United States nearly tripled from €13.0 million to €30.9 million (+138.2%), making it the EU's single largest destination. Shipments to India surged from €0.7 million to €14.3 million (+1,825%), and exports to Türkiye grew from €1.2 million to €2.7 million (+129.1%). This reorientation from east to west and south represents a structural realignment of the EU's fluorine salt export base, replacing a single proximate market with a more diversified but geographically distant set of buyers.

EU member states show sharply divergent patterns in trade participation

Import growth was not evenly distributed across EU member states. Several countries recorded explosive growth: Poland's imports surged from €0.9 million to €35.1 million (+3,769%), Hungary's from €0.5 million to €14.7 million (+3,162%), Slovenia's from €0.2 million to €7.4 million (+3,121%), and Ireland's from €0.4 million to €6.8 million (+1,527%). These dramatic increases in Central and Eastern Europe likely reflect the build-out of downstream processing or manufacturing capacity, possibly linked to the battery and electric-vehicle supply chain — lithium hexafluorophosphate and related fluorine salts are classified under CN 2826. On the export side, Germany remained the dominant exporter, growing from €61.5 million to €86.2 million (+40.1%) and accounting for roughly two-thirds of total EU export value by 2025. Lithuania (+61.8%) and Belgium (+30.5%) also expanded their export shares.

3. Structural Shifts: Falling Production, Price Turbulence, and Divergent Product Dynamics

EU domestic production contracted in volume but held steady in value

EU production of fluorine (measured in kg F) fell from 206.9 million kg in 2015 to 168.0 million kg in 2025 (−18.8%), while production value rose from €411.3 million to €430.0 million (+4.6%). This divergence — fewer tonnes at higher unit values — signals a combination of output rationalisation in energy-intensive capacity and a pass-through of rising energy and raw-material costs. The volume decline is consistent with the broader pressures on European basic chemistry, compounded by the 2021–2022 energy shock.

Import prices for complex fluorine salts reached extraordinary levels during the crisis

The most dramatic price movements occurred in sub-product 282690 (complex fluorine salts excluding synthetic cryolite). The import price for this category surged from €1,215 per tonne in 2015 to a peak of €6,923 per tonne in 2022 — a more than five-fold increase — before easing to €3,799 per tonne in 2025. This single sub-product drove the majority of the overall import value spike: its import value rose from €24.4 million in 2015 to a peak of €145.0 million in 2022, then retreated to €80.1 million by 2025.

Import prices for other sub-products evolved differently, as the table below shows:

Product segments display contrasting trajectories in volume and price

Import volumes by sub-product reveal sharply divergent trends. Synthetic cryolite (282630) saw the fastest volume growth, from 1,683 tonnes to 8,646 tonnes (+413.7%), yet its import value only rose from €0.7 million to €1.8 million — a consequence of unit prices that collapsed from €393 per tonne to €210 per tonne. This pattern is consistent with large-scale Chinese overcapacity in synthetic cryolite flooding the EU market at declining prices. Aluminium fluoride (282612) imports were volatile, peaking at 13,017 tonnes in 2017 before settling at 6,661 tonnes in 2025. On the export side, non-aluminium fluorides (282619) emerged as the fastest-growing category, with volumes rising from 5,280 tonnes to 14,755 tonnes (+179.4%), while synthetic cryolite exports contracted from 8,672 tonnes to 5,125 tonnes (−40.9%).

Market concentration trends reveal asymmetric evolution

The Herfindahl-Hirschman Index (HHI) for imports by value rose from 3,358 to 3,732 (+11.1%), confirming that import sourcing became more concentrated — primarily around China. By contrast, the export HHI fell from 2,261 to 1,754 (−22.4%), reflecting the diversification away from Russia and toward new markets. Among EU member states, Slovenia showed the highest export specialisation (RCA of 11.57), followed by Belgium (RCA 1.99) and Germany (RCA 1.61), while Finland, Croatia, and Portugal showed virtually no specialisation in this product. This asymmetric evolution — more concentrated imports alongside more diversified exports — means the EU has become simultaneously more competitive in its outward-facing trade and more dependent on a narrower set of suppliers.

Conclusion

The EU's trade in CN 2826 over 2015–2025 tells a story of vulnerability, crisis, and partial recovery. A period that began with a comfortable €43 million export surplus was upended by the convergence of declining domestic production (−18.8% by volume), the 2021–2022 energy price shock, and surging dependence on Chinese imports. The import crisis of 2022 — when import values spiked to €184.5 million, driven overwhelmingly by a near five-fold increase in unit prices for complex fluorine salts — pushed the EU into a trade deficit of nearly €100 million and net import reliance of almost 23%. By 2025, the situation had partially normalised: the trade balance returned to a small surplus of €4.2 million, and import prices had eased from their peaks. However, structural vulnerabilities persist. EU fluorine production continues to decline in volume, China has consolidated its position as the dominant supplier with an increasingly concentrated import base, and the sector's overall trade openness has risen significantly. The geographic reorientation of EU exports — away from Russia and toward the United States, India, and Türkiye — provides a measure of resilience, but the growing concentration of imports around a single supplier represents a strategic dependency that warrants attention, particularly as fluorine salts become ever more critical for battery technologies and the broader energy transition.
