Market evolution: Casein and caseinates (CN 3501) — 2015–2025

Introduction

This report examines the European Union's external trade in casein, caseinates and other casein derivatives (customs code 3501) over the 2015–2025 period. The product group encompasses raw casein, caseinates used primarily in food and pharmaceutical applications, and casein-based glues. Over the decade, the EU has consolidated its position as a major net exporter, with trade value showing strong growth in exports while imports have contracted significantly. This report identifies three principal dynamics: the structural shift toward a deeply negative net import reliance, the geographic reorientation of both trade flows, and the significant price shocks that reshaped market conditions from 2021 onwards.

1. The EU's Deepening Self-Sufficiency and Export-Led Growth

The most striking feature of the period is the EU's transformation into a deeply self-sufficient and export-oriented casein producer. The trade balance widened substantially, and domestic production expanded to meet both internal and external demand.

The trade surplus expanded dramatically

The EU's trade surplus in casein products grew from €415.1 million in 2015 to €586.8 million in 2025, a 41.4% increase. Over the same period, exports rose from €553.9 million to €655.4 million (+18.3%), while imports collapsed from €138.8 million to €68.6 million (−50.6%).

Net import reliance swung to strongly negative values

The net import reliance indicator moved from −14.1% in 2015 to −62.4% in 2025, reaching a trough of −101.6% in one intervening year. Negative values indicate that the EU exports far more than it imports — meaning the bloc is not merely self-sufficient but a dominant global supplier. This deepening reliance on exports rather than imports underscores the structural competitiveness of EU casein producers.

Domestic production surged to support export growth

EU domestic production volumes grew from 214.7 million kg in 2015 to 341.8 million kg in 2025 (+59.1%), while production value rose from €900 million to €1.61 billion (+79.2%). This expansion, outpacing even the increase in export value, suggests that rising domestic consumption — particularly of caseinates in food manufacturing — has also absorbed a share of the output, even as the EU maintained its role as a leading exporter.

Export prices outpaced import price increases

Export unit values rose by 11.7% over the period (from €6,356/t to €7,102/t), while import prices increased by only 6.9% (from €5,995/t to €6,409/t). This divergent price trajectory may reflect the EU's specialization in higher-value processed caseinates and derivatives, which command a premium relative to bulk casein sourced from third countries.

2. Geographic Reorientation: New Partners and Shifting Concentrations

Trade flows underwent significant geographic restructuring on both the import and export sides, reflecting changing sourcing strategies, geopolitical developments, and the growing importance of Asian markets.

Import dependency on New Zealand declined sharply

New Zealand remained the largest single source of EU casein imports but saw its share erode dramatically — from €90.1 million in 2015 to €32.8 million in 2025 (−63.7%). Ukraine, the second-largest supplier, also contracted from €27.0 million to €18.4 million (−31.8%). Meanwhile, Belarus saw a modest increase (+37.0%), and India collapsed from €5.4 million to €1.1 million (−80.0%).

This contraction was driven partly by the declining import volumes: total imports fell from 23,153 tonnes to 10,702 tonnes (−53.8%). The EU's expanding domestic production capacity reduced its need for external sourcing.

Within the EU, Poland emerged as the primary import hub

Among EU Member States, import patterns shifted markedly. Germany's imports fell from €57.7 million to €11.1 million (−80.7%), while the Netherlands dropped from €34.6 million to €15.2 million (−56.1%). Poland, by contrast, maintained relatively stable imports (€32.1 million to €35.8 million, +11.7%) and became the EU's largest importing Member State by 2025.

China became the fastest-growing export destination

On the export side, China's demand surged by 519%, from €13.4 million to €83.2 million, making it the EU's fourth-largest export market. Mexico also grew strongly (+73.4%, from €37.0 million to €64.2 million). The United States remained the largest single destination, though essentially flat at around €149–150 million. Other Asian markets — Korea (+43.1%), Russia (+25.4%), and the UK (+60.6%) — also expanded.

Ireland consolidated its dominance as the EU's export powerhouse

Within the EU, Ireland's exports grew from €176.7 million to €311.9 million (+76.5%), representing nearly half of all EU exports by 2025. Ireland's Revealed Symmetric Comparative Advantage (RSCA) of 0.89 confirms an exceptionally strong specialization in casein products. France (+52.2%) and Spain (+3,502% from a low base) also expanded their export shares, while the Netherlands experienced a steep decline (−66.3%).

Trade concentration declined on both sides

The Herfindahl-Hirschman Index (HHI) for imports fell from 4,666 to 3,446 (−26.1%), and for exports from 1,482 to 937 (−36.8%). Both values indicate a moderate-to-competitive market structure that became less concentrated over time. The declining import HHI reflects the erosion of New Zealand's dominant position, while the export-side decline points to a broader diversification of EU export destinations.

3. Price Volatility and the 2022 Supply Shock

The period was marked by significant price instability, culminating in a pronounced shock in 2022 that affected multiple trade relationships. Price dynamics varied considerably between the two sub-products.

Global supply disruptions drove a major price spike in 2022

The shock detection analysis identified three significant export price shocks centered on 2022. The most pronounced occurred in exports to the United States, where the price shift reached +68.8% with an abnormality score of 14.3 — representing 33.6% of total EU export value. Similar shocks were detected for Thailand (+71.0%) and Tunisia (+55.0%).

These synchronized price spikes likely reflected the combined effects of post-pandemic demand recovery, global dairy supply constraints, and the energy cost shock following the outbreak of the Russia-Ukraine conflict in early 2022.

Casein prices were more volatile than caseinate prices

Breaking down the two sub-products reveals distinct price trajectories. Casein (CN 350110) export prices peaked at €10,955/t in 2022 before falling back to €6,887/t in 2025. Caseinates and derivatives (CN 350190) prices peaked even higher at €12,605/t in 2022, settling at €7,734/t.

Import prices showed a similar pattern: casein import prices peaked at €9,797/t in 2022 (from €5,137/t in 2015), while caseinate import prices reached €11,644/t in 2022 before declining to €11,042/t in 2025.

Export volatility was generally lower than import volatility

The coefficient of variation (CV) for the EU's top export partners was relatively low — 0.13 for the United States, 0.15 for Korea, and 0.12 for the United Kingdom — suggesting stable, long-term trade relationships. By contrast, import-side volatility was higher, with New Zealand at 0.45, India at 0.83, and the United Kingdom at 1.20. This asymmetry reflects the EU's stronger bargaining position as a net exporter and the concentration of its import sources among fewer, more exposed partners.

Conclusion

Over the 2015–2025 period, the EU's casein and caseinates market underwent a structural transformation. The bloc consolidated its position as the world's leading net exporter, with production volumes growing by 59.1% and the trade surplus expanding by 41.4%. Ireland emerged as the dominant exporter, while the geographic footprint of EU exports shifted decisively toward Asia — with China growing by 519%. On the import side, the contraction was broad-based, with New Zealand's share declining steeply and Germany losing its position as the EU's primary import gateway to Poland. The 2022 price shock represented the most significant market disruption of the period, though prices have since normalized. Overall, the EU's casein sector demonstrates strong competitive advantage, diversified market access, and a high degree of self-sufficiency — positioning it well for continued growth in global dairy-derived protein markets.
