Market evolution: Iron and steel structures (CN 7308) — 2015–2025

Introduction

This report analyses the evolution of EU external trade in iron and steel structures and fabricated parts (CN 7308) over the 2015–2025 period. The product heading encompasses a wide range of fabricated steel goods — from bridges, towers and lattice masts to scaffolding equipment, doors and windows, and other structural components — excluding prefabricated buildings (heading 9406). The period under review captures a decade of significant upheaval: the post-2015 industrial recovery, the COVID-19 shock, the commodity price surge of 2021–2022, and the geopolitical reconfiguration triggered by the Russia–Ukraine conflict. Against this backdrop, EU trade in CN 7308 underwent a profound transformation — characterised by a dramatic import surge, a reorientation of supply chains toward new partners, and a shifting balance between domestic production and external sourcing.

1. A widening gap: import growth vastly outpaces export gains

The most striking macro-level dynamic over the decade is the divergence between import and export trajectories. While the EU remained a net exporter throughout the period, its trade surplus eroded sharply, driven by an unprecedented rise in import volumes and values.

1.1 Exports grew in value but stagnated in volume

Between 2015 and 2025, EU exports of CN 7308 rose from €7.02 billion to €9.79 billion, an increase of 39.4%. However, the underlying quantity moved only marginally — from 2.51 million tonnes to 2.60 million tonnes (+3.6%). The implication is clear: nearly all of the export value growth was driven by rising unit prices, which climbed from €2,802/t to €3,769/t (+34.5%), reflecting the post-2021 commodity price boom and inflationary pressures rather than a genuine expansion in export competitiveness.

1.2 Imports surged across all dimensions

By contrast, imports exploded in both volume and value:

Import volumes nearly tripled, while the EU's trade surplus shrank from €5.28 billion in 2015 to €3.62 billion in 2025 (−31.4%). The net import reliance indicator confirms this shift: while the EU remained a net exporter (negative values), the metric moved from −4.6% to −6.5%, indicating that the relative gap between imports and domestic production narrowed considerably. The trade intensity ratio — measuring total trade relative to production — more than doubled from 7.8% to 20.9%, confirming that the EU's iron and steel structure sector became far more exposed to international markets over the decade.

1.3 Domestic production surged, yet could not displace imports

A notable counterpoint is that EU domestic production also expanded dramatically — by weight, from 7.46 billion kg in 2015 to 37.86 billion kg in 2025 (+407.4%), and by value from €16.43 billion to €66.59 billion (+305.2%). This suggests that the import surge was not driven by a decline in domestic capacity, but rather by a structural increase in demand — likely linked to large infrastructure investment cycles (e.g., renewable energy, transport) and a broader expansion of construction activity across the EU. Import penetration thus grew in absolute terms even as the domestic industry scaled up.

2. A new geography of supply: the rise of Asian and Turkish suppliers

The import surge was not distributed evenly across partners. The period saw a dramatic reorientation of the EU's sourcing landscape, with China and Türkiye emerging as dominant low-cost suppliers, while the Russia–Ukraine conflict catalysed a near-total collapse in EU–Russia trade.

2.1 China and Türkiye became the EU's primary import suppliers

Among the EU's top import partners, two countries stand out for the scale and speed of their growth:

China alone accounted for €2.4 billion in imports by 2025 — nearly 39% of total EU imports — and its growth rate of 243.5% was accompanied by relatively low price volatility (coefficient of variation of 0.42). Türkiye's trajectory was even more striking: imports grew over nine-fold, from €105 million to €1.08 billion, making it the EU's second-largest supplier by value. The volatility data shows that Turkish import flows were considerably more volatile (CV = 0.77), suggesting a more episodic or project-driven supply relationship. Meanwhile, Viet Nam and India — while smaller in absolute terms — posted exceptional growth rates (+789% and +199% respectively), signalling a diversification of the EU's Asian sourcing base.

2.2 The collapse of EU–Russia trade in steel structures

Perhaps the most dramatic partner-level shift was the near-total evaporation of EU exports to Russia. Exports to the Russian Federation fell from €234.6 million in 2015 to just €2.7 million in 2025 (−98.9%), a direct consequence of the sanctions regime imposed following the 2022 invasion of Ukraine. This represents a significant loss of a once-sizeable market for EU fabricators, particularly those in Central and Eastern Europe that historically had strong trade ties with Russia.

2.3 EU exports remained concentrated in Western and Northern markets

On the export side, the top destination markets in 2025 were the United Kingdom (€1.70 billion, +109.2%), the United States (€1.66 billion, +194.5%), Norway (€1.05 billion, +54.3%), and Switzerland (€956 million, +28.3%). The US market stood out for its rapid growth, potentially reflecting infrastructure investment cycles and a preference for EU-sourced fabricated steel in certain high-specification applications. A notable anomaly was the surge in exports recorded under "High seas" — from €16 million to €1.02 billion — which likely reflects reclassification or offshore energy infrastructure projects rather than a conventional trade flow. The export concentration index (HHI) more than doubled from 525 to 1,123, indicating that EU exports became increasingly concentrated in a smaller number of destination markets — a potential vulnerability.

3. Internal reshuffling: production growth, specialisation, and product-level divergences

Beneath the headline trade figures, the internal structure of the EU's iron and steel sector underwent significant change. Production volumes surged, specialisation patterns shifted, and the product composition of both imports and exports diverged sharply.

3.1 Central and Eastern European economies emerged as specialised exporters

The specialisation analysis (2025) reveals that the EU's most specialised producers of CN 7308 products were concentrated in Central and Eastern Europe:

Poland's position is particularly significant: with an RCA of 2.45 and a 16.3% share of EU production, it is both a specialised and a large-volume producer. This aligns with Poland's emergence as a major exporter, where its exports grew from €454 million to €765 million (+68.5%). At the other end, large economies like France (RSCA = −0.63) and Sweden (RSCA = −0.31) were net importers of these products relative to their overall trade profiles.

3.2 Within the EU, import growth was led by Germany, Spain, and Ireland

The top EU Member State importers in 2025 were Germany (€1.07 billion, +116%), France (€411 million, +181%), Spain (€524 million, +722%), and Ireland (€318 million, +387%). Spain's seven-fold increase is particularly noteworthy and may reflect the country's large-scale renewable energy and infrastructure buildout over the period. The export side was dominated by Germany (€1.96 billion, stable), the Netherlands (€2.19 billion, +425%), Spain (€987 million, stable), and Denmark (€705 million, +392%). The Netherlands' explosive growth likely reflects its role as a logistics hub and the expansion of port-related fabrication and re-export activity.

3.3 Product composition diverged between imports and exports

The product segment breakdown reveals that the dominant sub-category for both imports and exports was 730890 — "other structures and parts of structures, n.e.s." — which accounts for roughly two-thirds of trade by value. However, the trajectories of sub-segments diverged:

On the import side, the general structural steel category (730890) and scaffolding equipment (730840) saw the largest absolute gains, consistent with booming construction demand. Towers and lattice masts (730820) also grew strongly, likely linked to wind energy expansion. Notably, imports of doors and windows (730830) actually declined in weight (from 94K t to 71K t), despite a rise in value, suggesting that this segment remained more competitive domestically or shifted toward higher-value products.

On the export side, scaffolding equipment exports declined from 469K t to 294K t (−37.3%), while tower and mast exports more than doubled (146K t to 322K t). Export prices for doors and windows (730830) were consistently very high — reaching €10,326/t by 2025 — reflecting the EU's comparative advantage in premium, value-added window and door systems. Bridge exports, while volatile, trended downward from 96K t to 50K t.

Conclusion

The decade 2015–2025 fundamentally reshaped the EU's position in global trade for iron and steel structures. While the EU remained a net exporter by value, its trade surplus narrowed substantially as imports nearly tripled in volume — driven by surging domestic demand for fabricated steel in infrastructure, energy, and construction. The supply landscape was redrawn: China consolidated its position as the dominant supplier, Türkiye emerged as a near-tenfold growth story, and smaller Asian economies like Viet Nam and India entered the picture. Simultaneously, the Russia–Ukraine conflict severed what was once a significant export market. Internally, production scaled up enormously, Central and Eastern European economies (notably Poland and the Baltic states) consolidated their specialised roles, and the product mix shifted toward higher-value segments. The EU's iron and steel structure sector thus entered 2025 as a more trade-intensive, more import-dependent, and geographically more diversified industry than it was a decade earlier — dynamic but also more exposed to external supply risks and price volatility.
