Market evolution: Turbine parts (CN 84069090) — 2015–2025

Introduction

This report examines the trade dynamics of EU extra-EU trade in parts of steam turbines and other vapour turbines, excluding stator blades, rotors and their blades (Combined Nomenclature code 84069090), over the period 2015–2025. The EU has consistently been a strong net exporter in this product category, maintaining a trade surplus that ranged from €233 million to €538 million across the period. EU domestic production value grew substantially, rising from approximately €689 million to €1.2 billion (+74.1%). Yet the headline stability in the trade balance masks profound structural shifts: a dramatic divergence between unit prices of exports and imports, a geographic reorientation of both supplier and customer bases, and increasing concentration in trade flows. These dynamics are shaped by the broader energy transition, the long investment cycles of power-generation equipment, and evolving competitive pressures from Asian manufacturers.

1. The Price–Volume Divergence: Fewer Tons, Greater Value

EU export values rose even as volumes collapsed

The most striking feature of the 2015–2025 period is the sharp decoupling of EU export values from export volumes. Over the full period, EU exports of turbine parts rose in value from €484.5 million to €545.3 million (+12.5%), while the physical quantity shipped fell from 21,581 tonnes to just 13,010 tonnes (−39.7%). This implies a near-doubling of the average export unit price, from €22,451 per tonne in 2015 to €41,911 per tonne in 2025 — an increase of 86.7%. The minimum annual export value was €298.1 million and the peak reached €614.6 million.

This pattern is consistent with a shift in the EU's export basket toward higher-complexity, higher-value-added turbine components — the kinds of precision-engineered parts that accompany premium turbine systems for gas-fired and combined-cycle power plants, or nuclear and industrial steam applications. As global power generation increasingly demands reliability and efficiency, EU manufacturers appear to be competing on technology and quality rather than volume.

Import volumes surged while unit prices declined

The mirror image occurred on the import side. EU imports grew in value from €113.2 million to €125.7 million (+11.1%), but volume nearly doubled from 4,804 tonnes to 8,977 tonnes (+86.9%). The average import unit price fell from €23,555 per tonne to €14,004 per tonne (−40.5%). This divergence suggests that the EU is increasingly sourcing lower-value, more commoditised turbine components from abroad — particularly from emerging Asian suppliers that compete on cost.

The net effect is that the EU's trade balance in value terms remained solidly positive throughout, rising from €371.4 million to €419.6 million (+13.0%), even though the tonnage gap narrowed considerably.

Production value grew strongly, signalling an expanding domestic base

According to PRODCOM production data, EU domestic production of turbine parts rose from approximately €689 million to around €1.2 billion over the period, a gain of 74.1%. This suggests the EU's turbine-parts manufacturing base expanded meaningfully, likely driven by investment cycles in both conventional and renewable-adjacent power infrastructure. The production peak was €1.44 billion. This expansion underpins the EU's capacity to sustain high-value exports while also meeting growing domestic and intra-EU demand.

2. Geographic Reorientation: Asian Suppliers Rise, the US Dominates as a Customer

China and India surged as import sources, while Japan retreated

The partner-level import data reveals a dramatic reshuffling of the EU's supplier base. Chinese exports of turbine parts to the EU grew from €5.0 million in 2015 to €42.5 million in 2025 — an extraordinary increase of 744.6%. India's growth was even more striking in percentage terms: from €1.1 million to €16.2 million (+1,335.8%). Brazil also grew significantly, from €5.2 million to €8.8 million (+69.1%).

By contrast, Japan — the largest single import partner in 2015 at €35.0 million — saw its share collapse by 79.0% to just €7.3 million. This likely reflects the broader decline of Japanese heavy-industry exports in the face of Chinese and South Korean competition, as well as shifts in yen competitiveness. Indonesia, a minor supplier in 2015 (€1.1 million), essentially disappeared from the EU's import map by 2025 (€531). The overall import concentration by value (HHI) rose from 1,615 to 1,782 (+10.4%), indicating that imports are becoming somewhat more concentrated among fewer origins — driven by the dominance of China. By volume, concentration rose even more sharply, from 1,434 to 4,147 (+189.2%), confirming that China's rising volumes are a structural shift, not just a price phenomenon.

The United States became the EU's single largest export market

On the export side, the United States consolidated its position as the EU's top customer. EU exports to the US grew from €63.3 million to €124.6 million (+96.7%), nearly doubling. This likely reflects the US power sector's large-scale investment in gas-fired generation and maintenance of existing steam turbine fleets, combined with the premium placed on European-engineered components.

Iran, by contrast, saw a sharp decline of 72.8% (from €29.0 million to €7.9 million), almost certainly reflecting the impact of international sanctions and trade restrictions. Türkiye more than doubled its imports from the EU (+114.4%), while India grew by 47.1%.

Germany, Italy and Poland anchored EU exports; intra-EU production hubs shifted

Among EU Member States, Germany remained the largest exporter at €180.5 million in 2025 (up from €143.6 million, +25.7%), followed by Italy (€137.5 million, +12.2%) and Poland (€91.0 million, +9.1%). Czechia also emerged as a significant player, growing from €31.6 million to €43.6 million (+37.7%). Austria, however, saw a dramatic decline of 90.0% (from €26.6 million to €2.6 million), and France's exports fell by 38.5%. On the import side, Poland was the largest EU importer in 2015 (€37.5 million) but shrank to €13.3 million (−64.5%), while Germany and France grew as importing members, consistent with their expanding manufacturing bases needing imported components.

3. Rising Concentration, Emerging Vulnerabilities, and Price Shocks

Export specialisation is concentrated in Central and Eastern Europe

The revealed comparative advantage analysis for 2025 shows that several Central and Eastern European Member States display strong specialisation in turbine parts. Hungary leads with an RSCA of 0.71 and an RCA of 5.84, meaning its share of exports in this product is nearly six times the EU average. Romania (RSCA 0.55, RCA 3.42), Italy (RSCA 0.40, RCA 2.35), and Poland (RSCA 0.39, RCA 2.28) follow. These countries host major turbine manufacturing and component supply-chain facilities.

At the other end, several Member States show essentially no specialisation (Lithuania, Estonia, Ireland, Greece, Belgium — all with RSCA near −1.0), which is unsurprising for economies without significant heavy-machinery manufacturing bases.

Export concentration has increased, raising concentration risk

The Herfindahl-Hirschman Index for exports by value rose from 562 to 889 (+58.3%) over the period. While this remains below the 1,000 threshold typically considered "moderately concentrated," the upward trend is notable. It reflects the growing dominance of the United States as an export destination, which alone accounts for an increasingly large share of the EU's extra-EU turbine-part exports. Export volume concentration rose even faster (+40.7%). On the import side, concentration by value increased more modestly (+10.4%), but volume concentration surged by 189.2%, driven by China's growing share.

This rising export concentration could pose a vulnerability: any slowdown in US power-sector investment or a shift in US trade policy could disproportionately affect EU turbine-parts exporters.

Price shocks occurred in niche markets with limited overall trade impact

The volatility analysis identified three notable price shock events in EU exports:

These extreme price spikes — involving abnormality scores far above typical thresholds — likely reflect lumpy, project-driven deliveries. Turbine parts are often shipped in large batches tied to specific power-plant construction or major overhaul projects; a single large shipment of high-value components can produce a dramatic one-year price spike when the prior baseline was low. Saudi Arabia's 2022 shock, for instance, coincides with the Kingdom's accelerated investment in power generation under Vision 2030.

On the import side, Japan (coefficient of variation 1.04) and Mexico (CV 2.29) exhibited the most volatile import flows, reflecting their roles as episodic rather than steady suppliers to the EU.

The EU remains structurally self-reliant, but trade openness has declined

The net import reliance indicator remained consistently negative throughout the period (around −62%), confirming that the EU is a strong net exporter of turbine parts. The minimum was −227.8% and the maximum was −51.7%, with very little net change (+0.4%). This stability in structural self-reliance is reassuring.

However, the trade intensity ratio — which measures total extra-EU trade (exports + imports) relative to production — fell from 78.4% to 61.1% (−22.1%). Export propensity similarly declined from 71.3% to 54.7% (−23.3%). Both indicators reached their minima in the 2020–2021 period, likely reflecting pandemic-related disruptions and a temporary reorientation toward intra-EU sourcing. While the partial recovery since then is evident, the overall trajectory suggests that the EU's turbine-parts sector is becoming somewhat more oriented toward its internal market, even as production has expanded.

Conclusion

Over 2015–2025, the EU's trade in turbine parts (CN 84069090) has undergone a significant structural transformation beneath a surface of apparent stability. The EU's trade surplus widened modestly to €419.6 million, and production value grew strongly to an estimated €1.2 billion. Yet three deep shifts stand out.

First, the EU has moved up the value chain in its exports: fewer tonnes are leaving the bloc, but at substantially higher unit prices, suggesting a focus on premium, engineered components. Second, the geographic landscape has been redrawn — China and India have emerged as major suppliers of lower-cost parts to the EU, while Japan has receded; on the export side, the United States has become the overwhelmingly dominant customer, and export concentration has risen significantly. Third, while the EU's net self-reliance in this product is secure, declining trade intensity and export propensity suggest a sector that is increasingly serving its own internal market.

The key risks going forward include over-dependence on the US as an export destination, growing competition from Chinese manufacturers whose presence in the EU market is expanding rapidly, and the inherent lumpiness of turbine-related project flows that can produce large year-to-year trade volatility. The energy transition will continue to shape demand dynamics: as the role of steam turbines evolves alongside the growth of renewables and the phasing-out of coal, the competitive positioning of EU manufacturers in this niche will depend on their ability to maintain technological leadership in the high-value segments where they currently hold the advantage.
