Market evolution: Carbonates and peroxocarbonates (CN 2836) — 2015–2025

Introduction

This report examines the trade dynamics of the European Union in carbonates and peroxocarbonates (Combined Nomenclature code 2836) over the 2015–2025 period. The product group encompasses a wide range of industrial chemicals, including soda ash (disodium carbonate), sodium bicarbonate, calcium carbonate, and lithium carbonates. By analyzing trade flows, partner concentration, and market structure, the following sections identify and explain the major evolutionary trends that have shaped the EU's position in this global market over the past decade.

1. The EU's export market became increasingly value-driven, shifting away from volume growth

The overall trajectory for EU exports over the period reveals a significant shift from volume-based to value-based growth. While the total value of exports increased by 23.3%, from €561.9 million in 2015 to €692.9 million in 2025, the volume exported declined by 16.6%, from 2.05 million tonnes to 1.71 million tonnes. This indicates that the EU has been exporting fewer physical goods at substantially higher prices.

Price escalation became the primary engine of export value growth

The average export price per tonne rose by 47.8% over the period, climbing from €274.16 in 2015 to €405.28 in 2025. This price growth was not linear; it accelerated sharply in 2022, reaching a peak of €545.22 per tonne, before moderating. This pattern suggests a response to broader inflationary pressures and input cost increases that characterized the global economy in the early 2020s. You can explore the detailed yearly figures in the General Overview.

Disodium carbonate (soda ash) and lithium carbonates drove most of the value volatility

The product segment breakdown shows that soda ash (283620) remains the largest export category by volume and value. However, its export volume decreased from 1.31 million tonnes in 2015 to 1.17 million tonnes in 2025. In contrast, lithium carbonates (283691), a critical battery material, exhibited extreme volatility. Its export value surged to over €281 million in 2022, likely reflecting soaring global demand and prices, before falling back to €28.6 million in 2025. This segment's instability underscores its growing strategic importance and sensitivity to the energy transition's demand cycles.

The United Kingdom and Türkiye emerged as key export destinations

Among the top export partners, the United Kingdom has consistently been the largest market, with export values growing by 44.3% to €69.1 million. The most dramatic growth occurred with Türkiye, where exports increased by 90.1% to €52.2 million, solidifying its position as a major regional destination. Meanwhile, exports to Brazil and Egypt remained significant but experienced more modest growth or decline. The shift in partner performance is detailed in the Top Partners by Value section.

2. Import supply concentration intensified, led by a dominant Turkish partnership

In parallel with export trends, EU imports of carbonates also underwent a major transformation, characterized by rising value, stable volumes, and a dramatic increase in supplier concentration.

Import values surged while volumes remained largely flat, indicating severe price inflation

Total EU import value rose by 62.1% from €603.7 million in 2015 to €978.5 million in 2025. Import volumes, however, saw only a minor decline of 4.7%, moving from 3.26 million tonnes to 3.10 million tonnes. The average import price per tonne skyrocketed by 70.1%, from €185.43 to €315.33, mirroring the inflationary trend seen on the export side. This price surge is a primary driver of the deteriorating trade balance. The General Overview provides a comprehensive view of these aggregate shifts.

Türkiye consolidated its position as the EU's foremost carbonate supplier

The most striking change in the EU's import structure is the rise of Türkiye. Its share of import value grew from €156.1 million in 2015 (25.9% of total imports) to €549.5 million in 2025 (56.2% of total imports). This 252% increase makes Türkiye by far the dominant external supplier. This consolidation is a key factor behind the sharp rise in import concentration (Herfindahl-Hirschman Index for value), which more than doubled from 1,446 in 2015 to 3,454 in 2025, indicating a market moving from a diversified to a more concentrated structure. The visual evidence for this concentration can be found in the Concentration HHI data.

The product mix for imports shifted, with soda ash and sodium bicarbonate gaining prominence

Disodium carbonate (283620) is the largest import category by volume. Its import volume grew from 1.37 million tonnes in 2015 to 2.32 million tonnes in 2025. Sodium bicarbonate (283630) imports also expanded steadily, from 241,355 tonnes to 525,282 tonnes. Conversely, imports of calcium carbonate (283650) collapsed from 1.50 million tonnes in 2015 to just 126,610 tonnes in 2025, a drop of over 91%. This suggests a fundamental reorientation of sourcing or domestic production patterns within the EU for this specific product.

3. Growing net import reliance signals a shift in the EU's strategic dependency

Beyond bilateral flows, structural indicators reveal an evolving landscape of the EU's trade autonomy and vulnerability for this product group.

The EU's net import reliance grew substantially, eroding a former trade surplus

The net import reliance metric, which measures the EU's dependence on imports relative to its apparent consumption, moved from a small positive value of 4.8% in 2015 to 7.5% in 2025. More tellingly, the EU's trade balance in this product category deteriorated from a slight deficit of -€41.8 million in 2015 to a significant deficit of -€285.6 million in 2025. This shift is calculated by comparing the Net Import Reliance trends.

Trade intensity and export propensity both increased, highlighting the sector's integration into global markets

The EU's trade intensity (total trade as a share of production) rose from 24.4% to 36.9%, while its export propensity (exports as a share of production) increased from 11.8% to 19.5%. This indicates that while the EU is producing fewer carbonates (production volume fell by 21.6% over the period), the industry has become more reliant on both exporting and importing to meet demand. Germany, Bulgaria, and France are the most specialized producers, as measured by their Revealed Symmetric Comparative Advantage (RSCA), suggesting a core of competitive EU producers amidst declining overall output. The production and specialisation metrics are available in the Market Structure section.

Price volatility and supply shocks exposed vulnerabilities in key partnerships

An analysis of volatility (coefficient of variation) and detected shocks reveals that the EU's trade relationships are not without risk. For instance, imports from Norway and the United States exhibited very high price volatility. Furthermore, a significant price shock was detected for imports from Türkiye in 2022, where prices spiked by 75%, coinciding with its dominant market share. Similarly, export prices to Norway saw an extreme anomaly in 2022. These events, detailed in the Volatility & Shocks tab, highlight the potential costs of concentrated trade relationships in a volatile global market.

Conclusion

Between 2015 and 2025, the EU's trade in carbonates (CN 2836) underwent a fundamental transformation. The market evolved from a balanced, volume-oriented system into one characterized by high-value exchanges, deepening import dependency, and concentrated supply chains. EU exports became more focused on price rather than volume growth, while imports absorbed severe price inflation. The dramatic consolidation of Türkiye as the EU's primary supplier stands out as the defining structural change of the decade, directly contributing to a steep rise in import concentration and a worsened trade balance.

Concurrently, the EU's domestic production capacity contracted, leading to greater trade intensity and a measurable increase in net import reliance. The period was also marked by extreme price volatility, particularly in strategic segments like lithium carbonates and in key bilateral relationships. These trends collectively suggest that the EU's position in the global carbonates market is now more specialized but also more exposed to external price shocks and supply dependencies than it was a decade ago.
