Market evolution: Fan and compressor parts (CN 841490) — 2015–2025

Introduction

This report examines the EU's external trade in parts for air and vacuum pumps, gas compressors, fans, ventilating hoods, and related machinery (customs code CN 841490) over the period 2015–2025. These components are critical inputs for HVAC systems, industrial processes, automotive applications, and increasingly for clean-energy and data-centre infrastructure. Drawing on Eurostat trade data, the analysis identifies three overarching dynamics: a structural shift toward higher-value exports that has strengthened the EU's trade surplus; a reconfiguration of partner geography, with China consolidating its role as the primary import source while the UK and Japan have declined sharply; and growing concentration in trade flows alongside persistent volatility from geopolitical and pandemic-related shocks.

1. The EU consolidated its position as a net exporter through value-led growth

1.1. The trade surplus nearly doubled over the decade

The EU's trade balance in CN 841490 improved from €945 million in 2015 to €1.54 billion in 2025 — a gain of 62.4% (General Overview). This was not achieved by exporting more volume — tonnage actually declined by 6.2% — but by shifting toward higher-unit-value products. Export prices rose by 25.6%, from €28,637/t to €35,967/t, while import prices increased only 14.2%. The net import reliance indicator, which was already negative (indicating net exporter status) at −32.6% in 2015, deepened to −119.9% by 2025 (Net import reliance), confirming that the EU's export advantage has widened substantially.

1.2. Domestic production grew modestly while exports outpaced it

EU production of CN 841490 grew from an estimated €2.20 billion to €2.36 billion (+7.4%) over the period (Production volumes). Because exports grew faster than production, the export propensity — the ratio of exports to domestic production — rose from 107.2% to 125.7% (Export propensity). This implies that the EU is increasingly integrated into global supply chains for fan and compressor parts, exporting more than it produces domestically (with the difference reflecting re-exports of imported components and intra-EU production specialisation).

1.3. Germany and Italy anchored EU export capacity, but with divergent trajectories

Among EU Member States, Germany and Italy were the dominant exporters throughout the period (Top reporters):

Germany's exports surged by 60.4%, overtaking Italy as the EU's largest exporter. Italy, despite remaining a major player, saw its exports stagnate. Specialisation data confirms Italy's continued strength: it ranks second in the EU for revealed comparative advantage (RCA of 2.23), after Slovenia (RCA of 5.61), though Slovenia's absolute export share remains small.

2. The geography of trade partners shifted markedly, with China rising and traditional partners receding

2.1. China became the EU's dominant import source

The most significant structural change on the import side was the rise of China. EU imports from China grew from €354 million to €578 million (+63.4%), making China the single largest import partner by a wide margin. China's imports were characterised by relatively low volatility (coefficient of variation of 0.12), indicating steady, structural growth rather than episodic surges. This pattern is consistent with China's expanding manufacturing base in HVAC components and industrial machinery.

2.2. Japan and the UK experienced sharp declines as import sources

In contrast, imports from Japan collapsed from €405 million to €133 million (−67.1%), and imports from the UK fell from €217 million to €136 million (−37.5%). The Japanese decline may reflect the relocation of production to lower-cost Asian economies (including China), while the UK decline likely reflects post-Brexit trade friction and the reclassification of intra-EU trade flows.

2.3. Export destinations diversified, with the US and India driving growth

On the export side, the United States was the EU's fastest-growing major market: exports rose from €366 million to €631 million (+72.6%), making it the largest single export destination. India was the second-fastest-growing market among major partners, with exports nearly doubling from €73 million to €143 million (+97.1%). This likely reflects India's rapid industrialisation and infrastructure investment.

The UK, by contrast, was the only major export market to decline — from €257 million to €171 million (−33.6%) — consistent with post-Brexit trade diversion. Meanwhile, exports to China (+38.8%), Switzerland (+60.9%), Brazil (+58.1%), and Türkiye (+38.0%) all grew robustly.

2.4. Concentration increased on both sides of the trade ledger

The Herfindahl-Hirschman Index (HHI) for import concentration rose from 1,302 to 1,545 (+18.7%) by value, and from 1,600 to 3,006 (+87.9%) by volume (Concentration). Export concentration also increased, though from a lower base (HHI from 581 to 748 by value). The sharp volume-based concentration increase on the import side is particularly noteworthy: it indicates that the EU is sourcing a larger share of its import tonnage from fewer origins — primarily China — which could create supply-chain vulnerability.

3. Geopolitical shocks and pandemic effects introduced episodic volatility alongside structural change

3.1. The UK and the US were the most volatile import partners

The coefficient of variation (CV) of import values reveals large disparities in partner stability:

The UK's high volatility (CV of 0.66) is consistent with the disruption caused by Brexit, which introduced new customs procedures and regulatory divergence. The US volatility (CV of 0.61) may reflect the impact of trade tensions and supply-chain restructuring during and after the pandemic. By contrast, China's low volatility (0.12) underscores its role as a stable, structural supplier.

3.2. Export volatility was highest for geopolitical-sensitive markets

On the export side, the Russian Federation exhibited the highest volatility (CV of 0.89), followed by Serbia (0.72) and South Korea (0.33). The Russian volatility is directly linked to the most dramatic shock event in the dataset: in 2023, the unit price of EU exports to Russia spiked by 520%, with an abnormality score of 20.5 — far exceeding any other detected shock. This almost certainly reflects the impact of EU sanctions following Russia's invasion of Ukraine: sanctions restricted the volume of exports, but the remaining trade may have shifted to higher-value goods, emergency supply channels, or re-routed goods, inflating the reported unit price.

3.3. Other detected price shocks were smaller but notable

Two other supply-shock events stand out in the data:

The 2022 Mexico shock (abnormality of 12.5, price shift of +43.1%) may reflect post-pandemic logistics bottlenecks and energy-cost pass-through during 2022's global supply-chain disruptions. The 2019 UAE shock (+44.7%) is smaller and harder to attribute definitively but could reflect compositional shifts in what was exported (e.g., a move toward higher-specification parts).

3.4. The COVID-19 pandemic caused a visible dip followed by a strong rebound

While the data is reported at annual frequency — making precise pandemic attribution difficult — the overall trade figures show that import volumes hit their minimum (116,086 t) sometime during the 2015–2025 window, and export values hit their minimum (€2.17 billion) at a point consistent with the 2020 recession, before recovering to record levels by 2025. This V-shaped recovery, combined with the post-2020 rise in unit prices across both imports and exports, suggests that the pandemic accelerated a pre-existing shift toward higher-value, potentially more specialised components.

Conclusion

Over the 2015–2025 decade, the EU's trade in fan and compressor parts (CN 841490) evolved in three reinforcing directions. First, the EU consolidated its role as a net exporter by raising unit prices faster than volumes declined, nearly doubling its trade surplus to €1.54 billion. Second, the geography of trade was reshaped: China became the dominant import source while Japan and the UK receded; on the export side, the US and India emerged as high-growth markets, while the UK declined. Third, growing concentration — particularly the 88% increase in import-volume HHI — and episodic shocks from Brexit, COVID-19, and sanctions against Russia introduced new vulnerabilities even as overall trade flows expanded.

Looking ahead, the EU's strong export propensity (125.7% of production) and deepening reliance on China as a supplier suggest that supply-chain diversification and resilience will be key policy concerns. The sector's integration into data-centre cooling, electric-vehicle thermal management, and industrial decarbonisation is likely to sustain demand growth, but the geopolitical risks highlighted by the 2023 Russia shock and rising import concentration warrant close monitoring.
