Market evolution: Maize (CN 1005) — 2015–2025

Introduction

Maize (corn), classified under customs code CN 1005, is one of the EU's most significant cereal imports. The code covers two sub-products: maize for feed and industrial use (100590), which accounts for the vast majority of trade volumes, and maize seed for sowing (100510), a much smaller but high-value niche. Over the decade from 2015 to 2025, the EU's maize trade landscape has been reshaped by a widening structural deficit, major geographic shifts in both supply and demand, and a severe price shock triggered by the 2022 global food crisis. This report examines these three dynamics in turn.

1. A Widening Structural Deficit: EU Maize Imports Outpace Exports

The trade balance deteriorated by over 200 % in ten years

The EU has been a structural net importer of maize throughout the period, and the gap has widened dramatically. In 2015, the trade balance stood at −€1.0 billion. By 2025, it had reached −€3.3 billion, a deterioration of 226.6 %. The deficit was at its widest in 2022 at −€5.6 billion, driven by the simultaneous surge in global grain prices and the EU's growing import dependency.

Import volumes grew substantially while export volumes contracted

The value trend is mirrored in physical flows. EU import quantities rose from 11.4 million tonnes in 2015 to a peak of 23.8 million tonnes in 2022, before settling at 18.6 million tonnes in 2025 (+62.3 %). Over the same period, export volumes fell from 4.4 million tonnes to 2.6 million tonnes (−41.1 %). The EU thus shifted from exporting roughly one tonne for every 2.6 imported in 2015 to one tonne for every 7.2 imported in 2025.

Unit prices more than doubled during the 2022 crisis before partially correcting

Both import and export unit prices followed a similar trajectory: relatively flat from 2015 to 2020, a sharp spike peaking in 2022, and a partial correction thereafter.

Export prices have consistently exceeded import prices, reflecting the EU's specialisation in higher-value shipments (including seed maize). The 2022 spike — import prices at €301/t and export prices at €407/t — coincided with the disruption of Black Sea grain flows following Russia's invasion of Ukraine.

Seed maize (100510) remains a small but valuable sub-segment

Breaking the aggregate down by sub-product, maize seed for sowing (100510) accounts for a tiny share of volumes but commands a large price premium. In 2025, EU imports of seed maize totalled 60,701 tonnes at an average price of €2,358/t, compared with 18.5 million tonnes of non-seed maize (100590) at €217/t. On the export side, seed maize volumes have trended gently upward since 2015 (from 100,806 to 73,665 tonnes in 2025, after a peak of 165,598 tonnes in 2022), with highly variable unit prices that reached €5,433/t in 2023.

2. Geographic Realignment: Shifting Suppliers and Evolving Destinations

Ukraine has consolidated its position as the EU's dominant maize supplier

Across the decade, import sourcing underwent a significant transformation. Ukraine was already the leading supplier in 2015 (€1.29 billion, 62 % of total imports by value) and remained so in 2025 (€1.76 billion, 42 %). Its position strengthened during the 2022 crisis when Ukrainian maize imports peaked at €3.4 billion. Despite the logistical disruptions caused by the war, Ukraine's relatively low coefficient of variation (0.28) confirms it remained the most stable large-volume supplier over the period.

Brazil and North America surged to fill the EU's growing demand gap

The most striking partner-level shifts concern Brazil, Canada, and the United States:

Brazil's imports surged during the 2022 crisis (from €668 M in 2021 to €2.3 billion in 2022) but have since receded. The United States and Canada, by contrast, have seen sustained growth, with US imports rising nearly tenfold over the decade — reaching €1.1 billion in 2025, the second-highest source after Ukraine. This indicates a long-term diversification of the EU's maize supply base.

Traditional Balkan and Russian suppliers have sharply declined

In the opposite direction, Serbia's maize exports to the EU fell from €161 M in 2015 to just €59 M in 2025 (−63.6 %). Russian maize shipments collapsed almost entirely, from €91 M to €1.3 M (−98.6 %), a decline that accelerated after 2022. Moldova similarly contracted by 41.5 %. These reductions reflect both geopolitical realignment and competitive displacement by larger, more efficient producers.

Import concentration decreased, indicating a more diversified supply base

The Herfindahl–Hirschman Index (HHI) for EU maize imports fell from 4,059 in 2015 to 2,819 in 2025 (−30.5 % by value). While the market remains moderately concentrated (Ukraine alone still accounts for over 40 % of import value), the HHI decline confirms that the EU has actively diversified its supplier portfolio — a strategic response to the supply-chain vulnerabilities exposed in 2022.

The UK remains the anchor export destination, but niche markets have shifted

On the export side, the United Kingdom has consistently been the top destination, accounting for €236 M in 2025 (up 23.2 % from 2015). Türkiye remained a stable secondary market (~€108 M). However, several former destinations have largely disappeared:

• South Korea: from €75 M in 2015 to €0.1 M in 2025 (−99.8 %)
• Iran: from €44 M to €11 M (−74.2 %), with extreme year-to-year volatility (CV = 0.96)
• Egypt: from €60 M to €17 M (−72.1 %)

Meanwhile, Lebanon grew from €29 M to €72 M (+145.5 %) and Switzerland from €36 M to €55 M (+51.7 %). The export HHI rose from 791 to 1,150 (+45.4 %), indicating that EU maize exports have become more concentrated on a narrower set of destinations.

Within the EU, Spain and Italy are the fastest-growing importers; Romania leads exports but is declining

Among EU Member States, import growth has been driven by southern and peripheral economies:

Spain alone accounts for over a third of EU maize imports by value in 2025, reflecting its large livestock feed sector. On the export side, Romania remained the largest EU exporter (€291 M in 2025) but its share has eroded (−41.5 %). Poland emerged as a notable new exporter, growing from just €5 M to €82 M (+1,612 %).

3. Price Shocks, Volatility, and the 2022 Global Grain Crisis

The 2022 shock was the defining event of the decade

The most dramatic price event in the data is the 2022 spike, when import prices jumped to €301/t (from €219/t in 2021) and export prices to €407/t (from €225/t). This was driven by the disruption of Black Sea grain corridors following Russia's full-scale invasion of Ukraine. Import volumes simultaneously surged to 23.8 million tonnes — the highest in the entire period — as EU buyers scrambled to secure alternative supplies, particularly from Brazil (where import value quintupled in a single year).

Specific detected shocks point to regional dislocations in 2017 and 2022

The algorithm identified three statistically significant shock events:

The two 2017 export-price shocks to Israel and Iran, while large in percentage terms, occurred on relatively small volumes and likely reflect one-off contract structures rather than systemic market dislocations. The 2022 Canadian import-price shock is more significant: it reflects the global repricing of maize during the Black Sea crisis, with Canada — then accounting for 7.3 % of EU import value — transmitting the global price surge into EU procurement costs.

Supply-source volatility varies widely, making diversification critical

The coefficient of variation (CV) of import values by partner reveals which supply routes carry the most risk:

The United States, despite becoming the EU's second-largest supplier by 2025, displays the highest volatility among major partners (CV = 1.49), with import values ranging from just €14 M in 2017 to €1.1 billion in 2025. This suggests a pattern of opportunistic, large-volume spot procurement rather than stable long-term contracting. Belarus, with a CV of 1.57, saw trade collapse from €69 M in 2020 to near zero, consistent with EU sanctions following the 2020 political crisis and the 2022 sanctions escalation.

On the export side, emerging-market destinations carry the highest volatility

EU maize export volatility is highest for non-traditional or geopolitically sensitive markets:

The UK and Switzerland are by far the most stable export markets (CV ~0.20), confirming their role as reliable, geographically proximate destinations. By contrast, exports to China, Morocco, Korea, and Iraq are highly erratic, suggesting episodic demand linked to local harvest shortfalls or policy changes.

Conclusion

Over the 2015–2025 period, the EU's maize trade has undergone a fundamental structural shift. The trade deficit has nearly tripled to −€3.3 billion, driven by a 62 % increase in import volumes and a 41 % decline in exports. Ukraine remains the cornerstone supplier, but the EU has meaningfully diversified its sourcing, particularly towards the United States, Canada, and Brazil — reducing import concentration (HHI down 31 %). The 2022 Black Sea crisis was the defining shock of the decade, temporarily pushing import values to €7.2 billion and prices above €300/t. While prices have since corrected, the crisis accelerated a lasting realignment of trade flows. Internally, southern EU Member States (Spain, Italy, Ireland) have become the primary importers, while Romania's dominance as an exporter is eroding and Poland is emerging. Looking ahead, the EU's heavy reliance on non-EU maize — particularly for animal feed — remains a structural vulnerability, with supply-route volatility underscoring the need for continued diversification and strategic stock management.
