Market evolution: Sodium bicarbonate (CN 283630) — 2015–2025

Introduction

Sodium bicarbonate (CN 283630) is a widely used inorganic chemical with applications spanning food processing, pharmaceuticals, animal feed, flue-gas treatment, and various industrial processes. This report examines the evolution of EU trade with non-EU countries over the period 2015–2025, drawing on customs data at annual frequency. The decade under review was marked by a fundamental structural shift: the European Union transitioned from being a net exporter of sodium bicarbonate to a net importer. This transformation was driven by a combination of rising import volumes—particularly from Türkiye and Bosnia and Herzegovina—modest export growth, a contraction in domestic production volumes, and significant price shocks linked to the 2022 energy crisis. The following sections unpack these dynamics in detail.

1. From Net Exporter to Net Importer: A Decade of Structural Reversal

The most striking feature of the 2015–2025 period is the reversal of the EU's trade position. At the start of the period, the EU enjoyed a trade surplus in sodium bicarbonate; by 2025, it had become a significant net importer.

1.1. Import growth outpaced exports by a wide margin

Between 2015 and 2025, EU imports of sodium bicarbonate grew from €58.5 million to €174.3 million in value (+198.3%) and from 241,355 tonnes to 525,282 tonnes in quantity (+117.6%). Over the same period, exports rose only modestly from €78.9 million to €82.5 million (+4.5% in value) and from 128,979 tonnes to 151,926 tonnes (+17.8% in quantity). The divergence between import and export trajectories is the central dynamic of this market.

1.2. The EU's net import reliance flipped sign

The net import reliance indicator captures this structural shift succinctly. In 2015, it stood at −19.1%, meaning the EU was a net exporter covering nearly a fifth of its consumption through external sales. By 2025, the indicator had turned positive at +12.5%, indicating that the EU now depends on imports to cover roughly one-eighth of its apparent consumption. This 165.6% swing reflects both the surge in inbound shipments and the stagnation of outward trade.

1.3. Domestic production volumes contracted sharply

EU production volumes fell from approximately 1,981 million kg to 1,000 million kg over the decade (−49.5%), while production value rose from €172.8 million to €480.0 million (+177.8%). The combination of lower volumes and higher values suggests significant capacity rationalisation and/or a shift toward higher-value product grades. The halving of output volumes is consistent with the EU increasingly relying on third-country suppliers to meet domestic demand.

1.4. The export propensity of EU production declined

The export propensity fell from 28.2% to 20.0% (−29.1%). A decade ago, more than a quarter of EU production was sold abroad; today only a fifth is. This declining outward orientation, combined with the production contraction, underscores the shift in the EU's role from a competitive exporter to a market increasingly supplied from abroad.

2. Shifting Geographies: Concentration Risks and New Supplier Dynamics

Behind the aggregate trade figures lie significant changes in the geographic composition of both imports and exports, with important implications for supply-chain concentration and vulnerability.

2.1. Türkiye emerged as the dominant import supplier

Among top import partners, Türkiye stands out decisively. Its exports to the EU grew from €25.2 million in 2015 to €105.2 million in 2025 (+317.8%), making it by far the largest single supplier, accounting for roughly 60% of total EU import value in 2025. Bosnia and Herzegovina also expanded strongly, from €13.4 million to €36.7 million (+174.1%). These two Balkan/Turkish suppliers together now dominate the EU's import basket.

2.2. Russia's near-complete exit and China's rapid entry

Russian imports collapsed from €3.1 million to €71,000 (−97.7%), almost certainly reflecting the impact of EU sanctions following 2022. Conversely, China's share surged from negligible levels (€0.2 million) to €7.7 million (+3,278.6%), while Singapore appeared as a new supplier at €1.4 million. These shifts suggest a partial reorientation of sourcing away from Russia toward Asian producers, though in absolute terms, Asian suppliers remain far smaller than Türkiye and Bosnia and Herzegovina.

2.3. Import concentration worsened markedly

The Herfindahl-Hirschman Index (HHI) for imports by value rose from 2,973 to 4,183 (+40.7%). An HHI above 2,500 is generally considered indicative of a highly concentrated market; the increase signals growing dependency on a small number of suppliers, principally Türkiye. By volume, the HHI similarly climbed from 3,763 to 5,119. This concentration represents a structural vulnerability: any disruption to Turkish or Bosnian production or logistics could have outsized effects on EU supply.

2.4. EU exports remained geographically diversified but showed selective growth

The top export destinations remained relatively stable, led by China (€5.8M), the United Kingdom (€9.3M), Switzerland (€9.7M), the United States (€5.6M), and Norway (€5.2M). Notable growth was recorded for Switzerland (+168.2%), Norway (+149.3%), and Brazil (+241.3%). The much lower export HHI (537 vs. 4,183 for imports) confirms that EU exports are far more geographically diversified than its imports.

2.5. Intra-EU production concentrated in a handful of specialised Member States

Specialisation data for 2025 shows that Bulgaria (RSCA: 0.83), Spain (0.58), France (0.39), Croatia (0.35), and Portugal (0.33) are the most specialised EU producers. Germany, despite being the largest exporter by value (€20.6M), does not feature among the most specialised, suggesting it functions partly as a re-export or logistics hub. On the import side, the largest EU Member State importers by value in 2025 were Italy (€28.4M), the Netherlands (€26.1M), Belgium (€26.6M), Spain (€18.8M), and France (€13.5M), with the Netherlands showing the most explosive growth (+1,920.2%).

3. Price Dynamics and the 2022 Supply Shock

The period under review saw notable price movements and at least one major supply shock, concentrated around the 2022 energy crisis.

3.1. Import prices rose while export prices declined

EU import prices increased from €242/t to €332/t (+37.0%) over the decade, while export prices fell from €612/t to €543/t (−11.3%). The persistent price gap—EU exports commanded prices roughly 60–160% higher than imports—reflects differences in product specification, quality certification, and proximity-to-market advantages. The rising import price trajectory, however, narrowed the gap somewhat, likely reflecting increased energy and logistics costs for third-country producers.

3.2. The 2022 energy crisis triggered severe price shocks in key supplier markets

The supply shock analysis identifies three major shock events:

The 2022 shocks affecting Türkiye and Bosnia and Herzegovina are almost certainly linked to the European energy crisis triggered by the Russia–Ukraine conflict. Sodium bicarbonate production is energy-intensive (the Solvay process), and both Türkiye and Bosnia and Herzegovina are geographically proximate to the affected energy markets. The combined abnormality of these two shocks—representing 100% of EU import value from these two suppliers—suggests a systemic cost transmission rather than idiosyncratic events.

3.3. Trade volatility was concentrated among newer and smaller suppliers

The volatility analysis reveals that import sources with the highest coefficients of variation were India (CV: 2.63), Ukraine (2.47), Egypt (2.17), China (1.99), and Singapore (1.57). These are precisely the newer, smaller suppliers that entered or expanded during the period. By contrast, the established suppliers—Türkiye (0.32), Bosnia and Herzegovina (0.15), and the United Kingdom (0.20)—showed much lower volatility, confirming their role as stable, long-term partners. On the export side, Chile (0.87), the United States (0.65), and China (0.55) showed the most volatility among major destinations.

3.4. EU trade intensity held steady even as the balance deteriorated

The trade intensity indicator—the ratio of total trade (imports + exports) to domestic production—edged up from 36.0% to 40.4% (+12.2%). This relatively modest change masks the compositional shift: the EU's economy became more trade-open in this product, but almost entirely through rising imports rather than exports. The salience analysis confirms that export propensity (score: 59.1) is a more significant vulnerability indicator than trade intensity (21.8), highlighting the erosion of the EU's outward competitiveness.

Conclusion

Over the 2015–2025 decade, the EU's sodium bicarbonate market underwent a fundamental transformation. The Union shifted from a net exporter with a €20.5 million trade surplus to a net importer facing a €91.8 million deficit. This reversal was driven by import volumes that more than doubled—led by Türkiye, which alone accounts for 60% of import value—while EU production volumes halved and export growth stalled. The import market became significantly more concentrated (HHI rising from 2,973 to 4,183), increasing the EU's exposure to supply disruptions from a small number of suppliers. The 2022 energy crisis crystallised this vulnerability, triggering severe price shocks in the two largest supplier countries. Looking ahead, the combination of declining domestic production capacity, growing import dependency, and rising supplier concentration presents strategic questions for EU industrial and trade policy in this essential chemical sector.
