Market evolution: Flat-rolled steel (CN 7210) — 2015–2025

Introduction

This report analyses the evolution of the European Union's external trade in flat-rolled products of iron or non-alloy steel (customs code 7210) between 2015 and 2025. The period is characterised by a fundamental structural shift in the EU's trade position. The Union has transformed from being a modest net exporter at the start of the period to a significant net importer by the end, a reversal driven by surging import volumes from a diversifying set of suppliers, coupled with a decline in export volumes. This transition has been accompanied by a general rise in trade values and unit prices, particularly in the post-pandemic years.

1. The EU's Pivot from Net Exporter to Net Importer

Over the 2015-2025 period, the EU's trade balance for CN 7210 products underwent a dramatic reversal, fundamentally altering the bloc's position in the global market for these steel products.

The Balance Swung Deeply into Deficit

In 2015, the EU held a positive trade balance of approximately €832 million in value terms. By 2025, this had shifted to a deficit of over €2.1 billion, representing a change of -356%. This reversal was not gradual but accelerated significantly from 2021 onwards. The net import reliance indicator, which measures the trade balance as a percentage of apparent consumption, confirms this structural shift, moving from near-zero (0.6%) in 2015 to 8.5% in 2025.

Import Growth Outpaced Declining Exports

The primary driver was the divergent trajectory of import and export volumes. While import quantities grew by 65.1% (from 3.9 million tonnes in 2015 to 6.4 million tonnes in 2025), export quantities contracted sharply by 41.8% (from 4.7 million tonnes to 2.8 million tonnes over the same period). This divergence widened significantly after 2020. Consequently, the trade intensity, measuring the share of trade in production, increased, indicating the EU's market became more integrated with and reliant on external suppliers.

2. Diversification of Suppliers and Shifting Partnerships

The surge in imports was not driven by a single source but by a notable diversification of supply origins, reshaping the EU's import concentration.

New Major Suppliers Emerged from Asia and the Mediterranean

While traditional partners like China remained significant, the most striking growth came from other nations. Imports from Türkiye, Viet Nam, and Taiwan saw explosive growth, with their import value increasing by 862%, 122,080%, and 476% respectively between 2015 and 2025. By 2025, Korea, Republic of had become the EU's second-largest supplier by value, overtaking China. This diversification reduced supplier concentration; the import Herfindahl-Hirschman Index (HHI) fell by 45% from 2,152 to 1,177, indicating a less concentrated and potentially more competitive import market.

The UK's Role Diminished for the EU

Conversely, the United Kingdom's role as both a supplier and a destination for EU exports declined. The value of imports from the UK fell by 39.7%, and its share of EU exports also contracted, reflecting the changing trade dynamics post-Brexit. For the EU, the UK's decline in export prominence (-45.8% by value) was partially offset by stronger exports to the United States (+102.4%) and Ukraine (+49.0%).

3. Price Volatility, Supply Shocks, and Increasing Vulnerability

The period was marked by significant price fluctuations, evidence of supply shocks, and growing indicators of the EU's strategic vulnerability in this sector.

Unit Prices Reached Unprecedented Peaks

Average unit prices for both imports and exports followed a similar, though not identical, trajectory. After relative stability, prices surged dramatically in 2021 and 2022, peaking for imports at €1,268 per tonne and for exports at €1,467 per tonne. This spike, a common feature across commodity markets, was driven by post-pandemic demand recovery, logistical disruptions, and rising energy costs. While prices receded from these peaks by 2025, they remained substantially above pre-2021 levels.

Evidence of Targeted Supply Shocks and High Volatility

The data reveals specific supply shock events, most notably a severe price shock in EU exports to the United States in 2022. Furthermore, volatility analysis shows that import relationships with partners like Ukraine (CV: 0.98) and Viet Nam (CV: 0.94) were highly unstable, indicating unpredictable supply streams. This environment, combined with a rising trade intensity, underscores the EU's increasing vulnerability to external market disruptions and geopolitical events in its supply chain for these critical industrial materials.

Conclusion

Between 2015 and 2025, the EU's market for flat-rolled steel (CN 7210) underwent a profound transformation. The bloc shifted decisively from a net exporter to a net importer, a change catalysed by collapsing export volumes and rapidly growing imports. This import growth was characterised by a strategic diversification away from traditional suppliers towards new sources in Asia and the Mediterranean, which reduced supplier concentration. The period was also defined by extreme price volatility and structural vulnerability, as the EU's growing reliance on external supplies exposed its industries to global market shocks. These trends highlight a significant evolution in the competitive landscape and strategic dependencies for one of the EU's foundational industrial materials.
