Market evolution: Prefabricated buildings (CN 940690) — 2015–2025

Introduction

This report examines the trade dynamics of CN 940690 — Prefabricated buildings, whether or not complete or already assembled (excl. of wood, and modular building units of steel), traded by the European Union with non-EU countries over the 2015–2025 period. The product category encompasses a range of non-wood prefabricated structures — including buildings primarily of iron or steel, mobile homes, and other prefabricated constructions — and is captured at the heading level across four bundled sub-categories (94069010, 94069031, 94069038, 94069090). The analysis draws on available yearly data from 2017 to 2025.

Throughout the period, the EU remained a net exporter of these products, but the structural foundations of that position have shifted dramatically. While the EU's trade surplus stood at €1.25 billion in 2017, it had contracted to just €473 million by 2025 — a decline of 62.0%. This erosion resulted from a combination of surging imports (up 194.6% in value) and declining export volumes (down 44.7%), partially offset by a sharp rise in export unit values (up 49.1%). The data points to a market in transition, where rising domestic demand is increasingly met by non-EU suppliers even as EU producers move upmarket.

I. From net exporter to import-dependent: the structural erosion of the EU's trade surplus

The surplus halved as imports tripled and export volumes collapsed

The headline dynamic of the 2017–2025 period is the dramatic narrowing of the EU's trade balance. Imports surged from €261 million to €769 million (+194.6%), while exports declined from €1.506 billion to €1.242 billion (−17.6%). Critically, the export decline was driven almost entirely by volume: physical shipments fell from 381,855 tonnes to 211,015 tonnes (−44.7%), a contraction that was only partially masked by higher unit prices.

While the EU's net import reliance remained negative (confirming the net-exporter status), its improvement from −3.7% to −2.5% signals a rapid convergence. Domestic production value nearly doubled, rising from €16.7 billion to €32.4 billion (+94.2%), suggesting that the growth in imports was driven not by a decline in EU manufacturing but by a faster acceleration of overall demand.

Imports became more concentrated on fewer suppliers, increasing vulnerability

The Herfindahl-Hirschman Index (HHI) for import concentration nearly doubled — rising from 1,477 to 2,778 by value (+88.1%) and from 1,679 to 3,302 by volume (+96.7%). While these levels still fall below the conventional 2,500 threshold for a "moderately concentrated" market (by value), the trajectory is unmistakable: import sourcing has become significantly more concentrated. By volume, the 2025 HHI of 3,302 clearly exceeds that threshold, indicating that a smaller number of partners now account for a growing share of physical inflows.

This concentration is heavily driven by China's dominant role, which grew from €74.7 million to €354.9 million (+375.0%) — accounting for 46.2% of all EU imports by value in 2025. The United Kingdom and Türkiye also registered sharp growth, but their market shares remain far smaller.

The emergence of the UK as the EU's second-largest import source is particularly noteworthy. Post-Brexit trade data suggests that UK prefabricated building exports to the EU have nearly octupled, possibly reflecting both reclassification effects and genuine supply reorientation following the UK's departure from the single market.

EU member states show divergent import trajectories

The import surge was not uniform across the EU. Several member states dramatically increased their non-EU purchases, while others saw more modest growth.

Ireland (+525.9%) and Poland (+788.0%) stand out as the fastest-growing importers. For Ireland, this likely reflects the country's housing and construction pressures; for Poland, the data may capture re-export activity or a broader integration into European prefabricated building supply chains. Meanwhile, the Netherlands' emergence as the EU's top importer (€123.4 M) — overtaking France — may partly reflect Rotterdam's role as a logistics hub.

II. The price–volume divergence: EU producers move upmarket as lower-end production shifts abroad

EU exports have become fewer but significantly more expensive

Perhaps the most striking feature of the trade data is the divergence between export volume and price. Over the period, the EU exported 44.7% less by weight but saw its average export price climb from €3,944/t to €5,882/t (+49.1%). Import prices, by contrast, rose only from €2,550/t to €2,949/t (+15.6%).

The EU's export price premium over imports nearly doubled, rising from +54.7% to +99.5%. This pattern is consistent with a structural shift: EU producers appear to be concentrating on higher-value, more complex prefabricated buildings — customised structures, higher-specification steel buildings, or buildings with higher fit-out levels — while lower-value, standardised production increasingly moves to non-EU manufacturers.

Sub-category trends confirm the upmarket shift

The product segment breakdown reveals how this dynamic plays out across the four sub-categories.

Export prices by sub-category (EUR/t):

Mobile homes (94069010) recorded the most dramatic price increase — from €3,494/t to €7,785/t (+122.8%) — even as export volumes fell from 13,313 t to 5,694 t (−57.2%). This suggests that EU mobile home exports have shifted heavily toward premium, high-specification units. The "other prefabricated buildings" category (94069090) also shows a strong upmarket trajectory, with prices rising 55.0%.

Import volumes by sub-category (tonnes):

Import volumes surged across nearly all sub-categories. The most notable growth was in mobile homes (+228.9%), followed by "other" buildings (+169.6%) and iron/steel buildings (+160.7%). The only exception was the iron-or-steel sub-category (94069031), which was roughly flat — possibly because this segment was already dominated by non-EU supply. These trends reinforce the narrative of growing import penetration in the segments where EU export volumes were declining most sharply.

EU export prices exceed import prices in every sub-category, but the gap varies

The widest price premium exists in mobile homes (94069010), where EU exports command nearly three times the import price. This is consistent with the EU specialising in high-end, often bespoke mobile home units for markets like Switzerland and Norway, while importing standardised units primarily from China and Türkiye. The steel building category (94069038) also shows a very large premium (+147.7%), indicating that EU-made prefabricated steel structures are substantially more expensive — and presumably more complex — than their imported counterparts.

III. Geopolitical disruptions and partner reconfiguration reshape the EU's trade geography

Russia's near-total exit from EU exports was the single largest structural shock

The collapse of EU exports to Russia — from €163.5 million in 2017 to €0.3 million in 2025 (−99.8%) — stands as the most dramatic single-country shift in the dataset. This was a direct consequence of EU sanctions imposed following Russia's invasion of Ukraine in 2022. The loss of Russia as a destination represented the disappearance of what was previously the EU's single largest export market by value, and it forced EU exporters to redirect capacity toward other destinations.

The coefficient of variation for Russian exports reached 1.14 — far above the EU-wide average — reflecting the abruptness of the sanctions-driven collapse. Belarus, closely linked to Russia economically, also showed extremely high volatility (CV = 1.01).

Export diversification partially compensated, with the US becoming a key growth market

EU exporters partially redirected their flows. Exports to the United States grew by 183.0%, from €47.7 million to €135.0 million, making the US the EU's fifth-largest export destination by 2025. Meanwhile, Switzerland and the United Kingdom maintained their positions as the EU's two largest export markets, with values of €149.9 million and €193.3 million respectively. Norway, however, saw a 44.9% decline in EU exports, and Egypt's collapse was even steeper (−93.3%).

Price shocks in conflict-adjacent markets signal supply chain fragility

The supply shock analysis identified several extreme price events concentrated in conflict-affected or geopolitically sensitive regions:

Ukraine's shock in 2022 coincides with the onset of war and likely reflects emergency procurement at elevated prices. Kazakhstan's 2023 shock — with an abnormality score of 60.1 — suggests a very unusual transaction or batch, possibly linked to EU-funded construction projects or re-routed supply chains. Egypt's 2021 spike preceded its subsequent collapse as an export destination, hinting at market instability. These events, while involving relatively small shares of total EU trade, illustrate the vulnerability of EU prefabricated building exports to geopolitical disruption in third-country markets.

EU exporters show contrasting trajectories — Baltic and Balkan states specialise while larger economies lose ground

The specialisation analysis for 2025 reveals a fragmented picture within the EU. Small Baltic and Balkan states — Croatia (RSCA: 0.87), Slovenia (0.67), Latvia (0.65), Lithuania (0.60), and Estonia (0.56) — show very high specialisation, indicating that prefabricated buildings represent a disproportionately large share of their export profiles. By contrast, large economies like Germany (RSCA: −0.51), Ireland (−0.55), and Greece (−0.61) are specialised importers, consistent with strong domestic demand but limited comparative advantage.

On the export reporter side, most major EU exporters saw declining values over the period — Spain (−54.9%), France (−35.5%), Poland (−37.9%), and the Netherlands (−31.6%) — while Germany (+12.3%) was the only top exporter to post a gain. This suggests that EU export capacity is concentrating in fewer member states, a trend that mirrors the import-side concentration dynamics.

Conclusion

The EU prefabricated building market (CN 940690) underwent a fundamental structural transformation between 2017 and 2025. The EU retained its net-exporter status, but the margin eroded sharply as imports nearly tripled in value while export volumes fell by nearly half. The market's evolution can be summarised in three dynamics: (1) a surge in imports, driven overwhelmingly by China and increasingly by the UK, which has raised the concentration of supply and associated vulnerability; (2) a pronounced price–volume divergence in EU exports, pointing to an upmarket specialisation as lower-value production shifts abroad; and (3) a dramatic reconfiguration of the EU's export geography, triggered by the loss of Russia and compensated only partially by growth in the US and resilience in Switzerland and the UK. Together, these trends paint a picture of a sector where EU production is growing in value and sophistication, but where the competitive landscape is being reshaped by geopolitical shocks and the accelerating capacity of non-EU suppliers.
