Market evolution: Wide flats (CN 721113) — 2015–2025

Introduction

This report examines the trade dynamics of wide flats (Combined Nomenclature code 721113) — flat-rolled products of iron or non-alloy steel, simply hot-rolled on four faces or in a closed box pass, not clad, plated or coated, with a width exceeding 150 mm but below 600 mm and a thickness of at least 4 mm, commonly used in construction, heavy engineering, and shipbuilding. The analysis covers the EU trade overview for the period 2015–2025, a decade marked by extraordinary shifts: the EU transformed from a significant net importer into a net exporter of this product, driven by a near-total collapse of inbound flows and a steady — though more modest — rise in outbound shipments.

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

1.1 The dramatic contraction of EU imports

The most striking feature of the 2015–2025 period is the near-total evaporation of EU imports of wide flats. In 2015, the EU imported 72,315 tonnes worth €36.1 million; by 2025, these figures had fallen to just 3,230 tonnes and €2.5 million — declines of −95.5% in volume and −93.2% in value. The import price, meanwhile, rose from €499/t to €765/t (+53.2%), indicating that the residual imports became progressively more expensive, likely reflecting niche or specialty supply rather than bulk commodity flows.

1.2 Resilient and growing exports

Over the same period, EU exports of wide flats grew steadily. Export value rose from €12.6 million to €19.4 million (+54.7%), and volume increased from 18,522 tonnes to 24,526 tonnes (+32.4%). Export unit values climbed from €679/t to €793/t (+16.8%). While the export growth is more modest in absolute terms than the import collapse, the combined effect was a dramatic swing in the EU's trade balance: from a deficit of −€23.5 million in 2015 to a surplus of +€17.0 million in 2025.

1.3 Net import reliance turned negative

The EU's net import reliance — defined as (imports − exports) / (production + imports − exports) — shifted from +5.4% in 2015 to −1.6% in 2025. A positive value indicates the EU depends on external supply to meet domestic demand; the negative reading in 2025 means the EU now produces more wide flats than it consumes domestically and ships the surplus abroad. Export propensity — exports as a share of production — surged from 1.5% to 5.3% (+241.3%), confirming a structural reorientation of EU output toward external markets.

2. Geopolitical Reorientation: Partner Concentration and New Destinations

2.1 Traditional import suppliers withdrew almost entirely

The collapse in imports was concentrated among the EU's historically dominant suppliers. Partner data reveals:

Switzerland and the United Kingdom together accounted for the overwhelming majority of inbound flows in 2015. By 2025, their combined share had collapsed to under €2.4 million. The UK supply shock detected in 2025 — with an abnormality score of 7.7 and a volume shift of −97.6% — is consistent with the broader post-Brexit trade friction and possible diversion of UK-origin steel. Türkiye was the only partner to show a significant absolute increase, though from a very low base.

2.2 EU export markets diversified and deepened

On the export side, the EU's main destinations for wide flats in 2025 were the United Kingdom (€8.2M), Switzerland (€7.2M), Norway (€1.1M), Serbia (€1.0M), and Bosnia and Herzegovina (€0.6M). Several markets showed remarkable growth:

The Russian Federation, once a meaningful destination (€781,646 in 2015), essentially disappeared by 2025 (€11,436, −98.5%), almost certainly reflecting EU sanctions imposed following Russia's invasion of Ukraine. Meanwhile, Serbia and Bosnia and Herzegovina — Western Balkans countries with deep industrial ties to the EU — emerged as fast-growing markets. The geographic reorientation is clear: the EU's export footprint shifted toward EFTA neighbours and Western Balkans nations while retreating from Russia.

2.3 Concentration patterns evolved differently for imports and exports

The Herfindahl-Hirschman Index (HHI) for imports by value declined modestly from 5,528 to 4,976 (−10.0%), still indicating a moderately concentrated import structure — though on a dramatically smaller base. The export HHI, by contrast, rose from 2,084 to 3,213 (+54.1%), meaning exports became more concentrated among fewer destination countries. The UK and Switzerland alone absorbed over 78% of EU export value in 2025, reflecting a growing dependence on two neighbouring markets.

3. Production Decline and Domestic Market Reconfiguration

3.1 EU production of wide flats fell sharply

Despite the EU becoming a net exporter, domestic production volumes of wide flats declined substantially. Production quantity fell from 1,944,929 tonnes in 2015 to 412,860 tonnes in 2025 (−78.8%), and production value dropped from €1.34 billion to €342 million (−74.4%). This indicates a structural contraction of the EU's wide-flats industry, likely driven by capacity rationalisation, decarbonisation pressures on steelmakers, and competition from substitute products and wider hot-rolled coils. The fact that both imports and production fell simultaneously — while exports grew — suggests that EU domestic demand for this specific product shrank considerably over the decade.

3.2 Specialisation remained geographically concentrated

Analysis of revealed comparative advantage (RSCA) for 2025 shows that wide-flat production and export capacity is concentrated in a handful of EU Member States:

Italy and Czechia stand out as both the largest producers and the most specialised in this product category. Conversely, large EU steel producers such as Spain (RSCA −0.988) and Finland (RSCA −0.996) show virtually no specialisation in wide flats, confirming that this is a niche product within the broader EU steel landscape.

3.3 The EU's role in global trade repositioned

The trade intensity index — measuring the EU's openness to trade relative to its GDP — remained broadly stable, moving from 8.2% in 2015 to 8.7% in 2025 (a modest +5.6%). This confirms that the overall trade orientation of the EU in this product did not dramatically intensify; rather, the composition of trade shifted fundamentally, from net intake to net outflow. The most salient dynamic was export propensity, whose salience score of 286 dwarfs the trade-intensity score of 47, underscoring that the defining story of this period is the EU's reorientation as an exporter.

Conclusion

The EU market for wide flats (CN 721113) underwent a profound transformation between 2015 and 2025. Imports collapsed by over 95% in volume, led by the near-complete withdrawal of Switzerland and the United Kingdom as suppliers. Exports grew more moderately but steadily, pivoting toward the UK, Switzerland, and Western Balkans markets, while Russian destinations disappeared under the weight of sanctions. Domestic production contracted sharply — by nearly 80% — indicating that the EU's total consumption of this product has declined significantly. The net result was a swing from a €23.5 million trade deficit to a €17.0 million surplus, and from positive net import reliance to negative. The EU's wide-flat market is now smaller, more export-oriented, and geographically concentrated in a handful of specialised producing Member States — principally Czechia, Italy, Sweden, and France. This structural evolution reflects the combined effects of post-Brexit trade disruption, geopolitical shocks (sanctions on Russia), EU steel industry rationalisation, and a broader shift toward higher-value or more strategically important steel product categories.
