Market evolution: Casein (CN 350110) — 2015–2025

Introduction

This report analyses the evolution of trade in Casein (CN 350110) for the European Union with non-EU countries from 2015 to 2025. Over this period, the EU's position in the global casein market underwent a fundamental transformation, shifting from a balanced trade profile to a net exporter. This report examines the key drivers behind this shift, the volatility in prices and partnerships, and the resulting structural changes in the market.

A Decade of Export-Led Growth: The EU's Strengthening Trade Position

The EU's trade in casein is characterized by a strong and expanding export sector, which has driven a significant improvement in the overall trade balance. While import volumes contracted, export volumes grew, leading to a substantial positive swing in net trade value.

Export Expansion Outpaces Import Decline

Between 2015 and 2025, the EU's exports of casein grew in both value and volume, while imports contracted sharply. This divergence is the primary reason for the strengthened trade position.

Diverging Trajectories of Key Partners

The EU's export growth was not uniform across all destinations, and its import sourcing consolidated around a smaller group of suppliers.

• Export Diversification and New Growth Markets: While the United States remained the EU's largest export market (value: 129.9 million EUR in 2025), the most dynamic growth occurred in other regions. Exports to Morocco (+298.2%) and Saudi Arabia (+256.5%) saw triple-digit growth, indicating successful market development in North Africa and the Middle East. The United Kingdom also became a much more important customer post-Brexit.
• Import Source Volatility: New Zealand remained the top supplier, though its share fell. More strikingly, imports from traditional partners like India (-85.7%) and the United States (-58.4%) collapsed. Conversely, imports from Belarus (+37.0%) increased, suggesting a reorientation of sourcing patterns.

Price Volatility and the 2022 Supply Shock

The period was marked by significant price volatility, culminating in a pronounced price shock in 2022 that affected both import and export markets, albeit to different degrees.

Cyclical Price Peaks and Valleys

The unit value (price per tonne) of EU casein trade fluctuated considerably, following global dairy market cycles. The EU's export price reached a record high of 10,955 EUR/t in 2022, before correcting in subsequent years.

The 2022 Price Spike: A Detected Market Shock

An analysis of volatility identifies 2022 as a year of significant price abnormality, particularly in exports to the United States and Egypt.

• United States (Export Price Shock): The price abnormality index was 16.2, with a year-on-year price shift of +67.0%. Given that the U.S. was the destination for 37.6% of export value in that period, this shock had a major impact on EU exporters' revenues.
• Egypt (Export Price Shock): A similar, though smaller-scale, shock was observed for exports to Egypt (abnormality: 13.4, shift: +51.9%).

These extreme price movements likely reflect the global dairy market's reaction to the post-pandemic demand surge, supply chain disruptions, and energy cost inflation in 2022.

The Structural Shift: From Net Importer to Major Exporter

The combined effect of growing exports and declining imports fundamentally altered the EU's strategic position in the casein market, moving it from a position of marginal self-sufficiency to one of clear export dominance.

The Swing in Net Import Reliance

The most striking metric is the net import reliance percentage, which measures the trade balance as a share of production plus imports. In 2015, this figure was -2.0%, indicating the EU was a very slight net importer. By 2025, it had plunged to -60.6%. This means the EU's casein exports significantly exceed its imports, underlining its role as a major global supplier.

Specialised Producers and Concentrated Exports

The EU's export strength is driven by a few highly specialised member states, while its import sources have become less concentrated.

• Export Specialisation: In 2025, Ireland (RSCA: 0.90) and France (RSCA: 0.61) displayed very strong revealed comparative advantage in casein exports, together accounting for over 70% of EU export value. This indicates a high degree of production specialisation.
• Declining Export Concentration: The Herfindahl-Hirschman Index (HHI) for export value fell from 1,933 in 2015 to 1,143 in 2025. While still concentrated, this decline points towards a broader base of exporting firms or countries.
• Domestic Production Trends: EU production quantity (in kg) decreased by 14.7% over the period, while production value rose by 45.5%. This suggests a shift towards higher-value casein products or significant inflation, allowing the sector to grow in value despite lower volumes.

Conclusion

Between 2015 and 2025, the EU's casein market evolved from a balanced trade stance into a distinctly export-oriented sector. This was driven by sustained growth in exports to a diversifying set of partners, most notably in the Middle East and North Africa, while import needs contracted. The period was punctuated by severe price volatility, with a dramatic shock in 2022. Structurally, the EU has cemented its position as a major net exporter, with trade flows increasingly specialised by member state. The deepening negative net import reliance underscores the sector's enhanced global competitiveness and reduced vulnerability to external supply, though its increasing exposure to global demand cycles introduces a different form of market dependency.
