Market evolution: Alkali metal silicates (CN 2839) — 2015–2025
Introduction
This report examines the evolution of the European Union's external trade in alkali metal silicates (customs code 2839) from 2015 to 2025. The analysis is based on annual trade data, covering imports, exports, partner dynamics, production, and market structure. Over the decade, the EU has consolidated its position as a net exporter of these products, characterized by a significant increase in export values, a strategic reshaping of its trading partnerships, and a notable rise in price volatility. The following sections detail these core trends and their potential implications.
The EU's Strengthening Position as a Net Exporter
Over the period analyzed, the European Union has transitioned into a more pronounced net exporter of alkali metal silicates. This is evidenced by a growing trade surplus and a divergence in the trends of import and export values and volumes.
A Widening Trade Surplus Driven by Export Value Growth
The EU's trade balance for CN 2839 shifted from a surplus of €10.5 million in 2015 to €35.2 million in 2025, an increase of 233.7% (Trade Overview). This growth was primarily fueled by a 39.9% rise in export value (from €49.1 million to €68.7 million), while import value decreased by 13.1% (from €38.6 million to €33.6 million). Crucially, this occurred despite export volumes remaining almost flat (-0.1%) and import volumes declining by 25.0%. This indicates that rising export prices (41.1% increase) were the dominant factor behind the value growth.
| Metric | 2015 | 2025 | Change |
|---|---|---|---|
| Export Value (€) | 49,140,093 | 68,726,360 | +39.9% |
| Import Value (€) | 38,600,967 | 33,557,997 | -13.1% |
| Trade Balance (€) | 10,539,125 | 35,168,363 | +233.7% |
| Export Quantity (t) | 68,299 | 68,212 | -0.1% |
| Import Quantity (t) | 66,133 | 49,603 | -25.0% |
Diverging Price Dynamics: Exporters Capture More Value
The average unit prices for both imports and exports increased, but the export price premium widened significantly. The average export price rose from €714/t in 2015 to €1,007/t in 2025. In contrast, the average import price increased from €584/t to €676/t over the same period. This growing price gap suggests that EU producers have been able to command higher prices in international markets, possibly due to product specialization, quality advantages, or shifts towards higher-value silicate segments.
Shifting Geographic and Partner Dynamics
The EU's trade partnerships for alkali metal silicates underwent substantial reshuffling, with a clear trend towards geographical and partner diversification in both imports and exports.
Reconfiguration of Key Import Sources
The concentration of EU imports, as measured by the Herfindahl-Hirschman Index (HHI), remained moderate but saw volatility. The import HHI by value decreased slightly by 5.2% (Concentration). This masks dramatic shifts among top partners. Imports from Switzerland collapsed by 93.3%, while those from the United Kingdom fell by 55.8%. Conversely, imports from Egypt surged by 190.0%, and those from Japan grew by 84.6%, becoming a major source.
| Top Import Partner | 2015 Value (€) | 2025 Value (€) | Change |
|---|---|---|---|
| Switzerland | 7,645,178 | 512,164 | -93.3% |
| United Kingdom | 7,123,017 | 3,149,879 | -55.8% |
| Egypt | 2,054,328 | 5,958,127 | +190.0% |
| Japan | 3,358,755 | 6,200,091 | +84.6% |
| China | 2,549,539 | 4,170,134 | +63.6% |
Diversification and Growth in Export Destinations
EU exports became more concentrated, with the export HHI by value increasing by 56.6%. However, this occurred alongside significant growth in several key markets. Exports to the United States grew by 267.8%, making it a top destination. Similarly, exports to Switzerland (+114.5%), the United Kingdom (+159.5%), and Türkiye (+148.4%) expanded substantially. This suggests the EU is successfully deepening its trade ties with developed economies and regional neighbours.
| Top Export Partner | 2015 Value (€) | 2025 Value (€) | Change |
|---|---|---|---|
| United States | 2,410,785 | 8,865,995 | +267.8% |
| Switzerland | 2,918,517 | 6,259,276 | +114.5% |
| United Kingdom | 1,926,822 | 5,000,301 | +159.5% |
| Türkiye | 2,880,461 | 7,154,296 | +148.4% |
| Norway | 2,970,605 | 3,915,506 | +31.8% |
Increased Specialization, Declining Production, and Emerging Vulnerabilities
The EU market is characterized by a high degree of internal specialization among member states in exports, a concerning trend in domestic production volumes, and an increasing susceptibility to price shocks in key partner markets.
Internal Specialization and the Role of Key Member States
The EU's export structure is highly specialized by member state, indicating a concentrated and efficient production base. In 2025, Poland, Denmark, and the Netherlands exhibited the highest Revealed Symmetric Comparative Advantage (RSCA) scores for CN 2839 (Specialisation). The Netherlands and Germany were the leading exporters by value, while Italy and the Netherlands saw the largest growth among major importing members.
A Significant Contraction in Reported Production Volumes
A critical underlying trend is the decline in EU production. Reported production quantity (in kg SiO2) fell by 32.9% from 2015 to 2025, dropping from 2.09 billion kg to 1.40 billion kg. Production value fell by 11.1% over the same period (Production Volumes). This decline, coupled with stable export volumes, suggests that the EU may be increasingly relying on inventory drawdowns or that production reporting has changed. It warrants monitoring as it could affect long-term supply capacity.
Heightened Price Volatility and Detected Supply Shocks
Trade volatility, measured by the coefficient of variation (CV), is high for several key partners. For instance, imports from the United Kingdom have a CV of 1.19, and exports to Tunisia have a CV of 1.45 (Volatility). Most notably, the data identifies significant price shocks concentrated in 2022. For example, export prices to the United States surged by 263.9%, and to Israel by 64.7%, events with high abnormality scores (Supply Shocks). These shocks likely reflect the broader global energy and supply chain disruptions of that year.
Conclusion
Between 2015 and 2025, the EU alkali metal silicates market matured into a structurally stronger net exporter position, with trade surpluses more than tripling. This success was built on value growth rather than volume expansion, driven by rising export prices and a strategic diversification of both import sources and export destinations. Domestically, the market is highly specialized, with production concentrated in a few member states.
However, these positive trends are accompanied by risks. The sharp decline in reported production volumes is a structural concern for long-term autonomy. Furthermore, increased trade concentration and high volatility with key partners—exemplified by the severe price shocks of 2022—highlight vulnerabilities in the supply chain. The EU's enhanced export propensity (Vulnerability) underscores its greater integration into global markets, which brings both opportunity and exposure to external disruptions. Monitoring production trends and partner volatility will be crucial for ensuring the resilience of this strategic chemical sector.
