Market evolution: Steel structures (CN 730890) — 2015–2025

Introduction

This report examines the evolution of EU extra-EU trade in CN 730890 — a residual category covering structures and parts of structures of iron or steel not elsewhere specified, excluding bridges, towers, doors, windows, and scaffolding equipment. The heading encompasses a broad range of fabricated steel products, from insulated sandwich panels (CN 73089051) to sheet-based structures (CN 73089059) and all other steel structures (CN 73089098). Over the 2015–2025 period, EU trade in this product category underwent a profound transformation: imports nearly quadrupled in value while exports grew at a more moderate pace, trade intensity more than tripled, and the supplier landscape shifted decisively toward Asia and the Western Balkans. The EU retained its status as a net exporter throughout, but its surplus narrowed substantially, signalling a structural opening of the market to third-country competition.

1. A Widening Gap: Import Growth Far Outpaces Export Expansion

EU exports grew in value but stagnated in volume

EU extra-EU exports of CN 730890 rose from €4.76 billion in 2015 to €6.91 billion in 2025, a gain of 45.3% in value. However, quantity growth was far more modest: exported volumes moved from 1.72 million tonnes to 1.85 million tonnes, an increase of only 7.5%. The difference is explained by a 35.1% rise in unit export prices, from €2,760/t to €3,729/t, indicating that the EU increasingly exports higher-value-added steel structures rather than competing on volume.

EU imports surged on all fronts — value, volume, and supplier count

Imports tell a radically different story. Over the same period, EU imports climbed from €1.10 billion to €4.35 billion (+294.3%), while quantities soared from 524,000 tonnes to 1.89 million tonnes (+260.3%). Import prices rose more gently (+9.4%), indicating that the import boom was driven predominantly by volume rather than price effects. By 2025, the volume of imports had nearly reached the volume of exports, a remarkable convergence from a starting point where exports were more than three times larger in tonnage.

The trade surplus narrowed but the EU remained a net exporter

The trade balance remained positive throughout the decade, declining from €3.65 billion in 2015 to €2.56 billion in 2025 (−29.8%). The net import reliance remained negative (−4.1% in 2015, −5.5% in 2025), confirming the EU's persistent net-exporter status. Yet the most striking metric is the trade intensity, which tripled from 6.5% to 19.9%, revealing that the EU steel structures market has become dramatically more internationalized over the decade.

The sub-line 73089098 drove the import surge

The product breakdown shows that the import explosion was overwhelmingly concentrated in CN 73089098 — "other" steel structures not principally of sheet. This sub-line's imports grew from 381,519 tonnes (€849 million) in 2015 to 1.61 million tonnes (€3.71 billion) in 2025, accounting for 85% of total import volume by 2025. By contrast, imports of sheet-based structures (73089059) and insulated panels (73089051) grew more moderately. On the export side, 73089098 also dominated but grew only from 1.21 million tonnes to 1.35 million tonnes, while the two sheet-based sub-lines were broadly flat or declining in volume.

2. New Suppliers, Vanishing Markets: The Geographical Reshaping of EU Trade

China, Türkiye, and Viet Nam emerged as dominant import suppliers

The most dramatic shift in the EU's import landscape was the rise of China from €393 million in 2015 to €1.76 billion in 2025 (+348%), making it by far the EU's largest single supplier. Türkiye grew even faster in relative terms (+925%), from €63 million to €642 million, while Viet Nam surged from just €8 million to €142 million (+1,646%), the fastest growth rate of any major partner. Together, these three Asian/Turkish suppliers accounted for roughly €2.55 billion, or nearly 59% of total EU imports, in 2025.

Western Balkan suppliers consolidated their position

Serbia and Bosnia and Herzegovina also grew rapidly as import sources, with imports from Serbia rising from €40 million to €146 million (+269%) and from Bosnia and Herzegovina from €33 million to €145 million (+339%). Their competitive cost base and proximity to the EU likely facilitated this growth, consistent with broader EU nearshoring trends in the Western Balkans. The United Kingdom also remained a major supplier, growing from €182 million to €659 million (+262%), possibly reflecting post-Brexit reclassification effects and continued industrial integration.

EU exports to the United States surged while Russia collapsed

On the export side, the most striking development was the near-total collapse of exports to Russia — from €164 million in 2015 to just €1.8 million in 2025 (−98.9%), almost certainly a consequence of EU sanctions following the 2022 invasion of Ukraine. In contrast, exports to the United States doubled from €404 million to €1.07 billion (+165%), making the US the EU's fourth-largest extra-EU export destination. The United Kingdom remained the top export market, growing from €576 million to €1.25 billion (+117%), followed by Norway (€524M → €864M) and Switzerland (€532M → €676M).

Import concentration rose, signalling growing dependency on fewer suppliers

The Herfindahl-Hirschman Index (HHI) for imports by value increased from 1,895 to 2,189 (+15.5%), moving into territory that could be described as moderately concentrated. This is primarily driven by China's growing dominance. The export HHI also more than doubled (572 → 1,218), partly reflecting the collapse of the Russia trade and growing concentration on the UK and US markets. Volatility analysis confirms the instability of some emerging suppliers: imports from the United Arab Emirates (CV 1.36) and Viet Nam (CV 1.09) showed the highest year-to-year variability among import partners.

3. Inside the EU: A Production Boom, Shifting Specialisation, and Dutch Export Surge

EU production volumes expanded dramatically — potentially reflecting data revisions

Reported EU production of CN 730890 products grew from 4.23 billion kg in 2015 to 33.15 billion kg in 2025 (+683.8% in quantity, +592.4% in value to €49.67 billion). These figures are extraordinarily large and may partly reflect changes in Prodcom reporting methodology or reclassification of products into this heading rather than purely organic growth. Indeed, the peak quantity reached 48.33 billion kg (in an intermediate year), suggesting significant volatility in the reported series. Even so, the underlying trend points to a substantial expansion of EU production capacity in steel structures, consistent with infrastructure investment cycles and the energy transition driving demand for structural steel components.

Central and Eastern European member states showed the strongest export specialisation

The specialisation analysis for 2025 reveals that the most specialised EU exporters in CN 730890 are predominantly Central and Eastern European member states:

Poland stands out as the only large economy among the most specialised producers, accounting for 18.5% of EU exports in this product. At the other end of the spectrum, Malta (RSCA −0.97), Ireland (−0.72), and France (−0.59) show strong negative specialisation, meaning they are net importers relative to their overall trade profile.

The Netherlands underwent a dramatic export transformation

Among EU member states, the most remarkable shift in export performance was recorded by the Netherlands, whose exports of CN 730890 surged from €318 million in 2015 to €1.92 billion in 2025 (+504%). This propelled the Netherlands from a distant second to the largest EU exporter, overtaking Germany (which declined from €1.18 billion to €1.11 billion, −6.1%). Denmark also grew strongly (€112M → €420M, +275%), while traditional exporters like Italy (−16.5%) and Spain (−1.4%) stagnated or declined. The Dutch surge likely reflects the role of Rotterdam as a logistics hub and possibly re-export activity, combined with growth in offshore energy infrastructure.

On the import side, Spain and Belgium experienced the steepest increases

Among EU member states as importers, Spain's intake grew from €44 million to €448 million (+914%), and Belgium's from €89 million to €321 million (+260%). Germany remained the largest importer (€313M → €644M), but its growth rate (+105%) was below the EU average. Ireland also saw a very steep rise (+458%, from €44M to €245M), potentially linked to its construction boom. These shifts suggest that the import surge was not uniform across member states but was concentrated in economies experiencing strong construction or industrial demand.

Conclusion

Over the 2015–2025 decade, the EU market for steel structures (CN 730890) underwent a structural transformation. The EU remained a net exporter, but its surplus shrank by nearly 30% as imports — driven overwhelmingly by volume growth from China, Türkiye, and increasingly Viet Nam — expanded almost fourfold in value. Trade intensity tripled to nearly 20%, indicating a market that has become deeply integrated into global supply chains. The Russia–Ukraine war and associated sanctions visibly redirected trade flows, collapsing EU exports to Russia while boosting demand from the United States. Within the EU, the Netherlands emerged as the dominant exporter, overtaking Germany, while Central and Eastern European member states consolidated their comparative advantage. The rising import concentration index (HHI) and the volatility of some newer supplier relationships highlight growing dependencies that may warrant attention from a supply-security perspective, even as the EU's overall net-exporter position persists.
