Market evolution: Motor vehicle radiators (CN 870891) — 2015–2025

Introduction

This report examines the trade dynamics of motor vehicle radiators and parts thereof (Combined Nomenclature code 870891) for the European Union over the 2015–2025 period. The product category covers radiators for tractors, passenger vehicles, goods vehicles, and special-purpose motor vehicles, along with their constituent parts. The EU has historically maintained a trade surplus in this segment, acting as a net exporter to the rest of the world. Over the decade, the sector has undergone significant structural shifts: import volumes have surged, sourcing patterns have been radically reconfigured, and intra-EU production has gravitated toward Central and Eastern European member states. At the same time, the EU has sharply increased its export orientation, with trade intensity and export propensity both roughly doubling. These developments reflect broader transformations in the European automotive supply chain, including the rise of Chinese manufacturing capacity, the post-Brexit reconfiguration of UK–EU trade flows, and the effects of geopolitical shocks on Eastern European sourcing.

The analysis draws on aggregate trade data, partner-level flows, production statistics, and concentration measures. All figures cited are sourced from the EU Trade Dashboard.

1. The EU's Expanding Surplus Masks a Decoupling of Volume and Value

Over the 2015–2025 period, the EU trade balance in radiators remained positive throughout, growing from €271 million to €297 million (+9.5%). However, the headline surplus figure conceals divergent dynamics on the export and import sides: while exports grew primarily through higher unit prices, imports expanded overwhelmingly through volume.

Export growth has been price-driven rather than volume-driven

EU exports of radiators rose from €737 million in 2015 to €956 million in 2025, a nominal increase of 29.7%. Yet over the same period, export volumes barely moved—edging up from 56,074 tonnes to 57,432 tonnes (+2.4%). The entire value increase can therefore be attributed to unit prices, which climbed from €13,141 per tonne to €16,640 per tonne (+26.6%). This pattern suggests that the EU has shifted toward higher-value or more specialised radiator products, while facing constraints on volume expansion.

Import growth has been volume-driven, with falling unit prices

Imports tell a strikingly different story. The EU's import bill grew from €466 million to €659 million (+41.5%), but import volumes surged from 40,379 tonnes to 60,139 tonnes (+48.9%). Import prices actually declined from €11,540 to €10,961 per tonne (−5.0%). This divergence—rising volumes, falling prices—is consistent with increasing penetration by lower-cost producers, most notably China, India, and Turkey, who have expanded their export capacity during this period.

The widening gap between export and import unit prices—from €1,601/t in 2015 to €5,679/t in 2025—underscores a growing product-composition differential. The EU appears to be importing increasingly commoditised or standardised radiators and parts, while exporting higher-specification components that command a premium.

2. Import Sourcing Has Been Fundamentally Reconfigured Around China

The most dramatic structural shift in the EU radiator market concerns the geography of imports. Over the decade, China has cemented its position as the dominant supplier, while South Korea and the United States have experienced steep declines. The import concentration index (HHI) has risen sharply, reflecting growing reliance on a smaller number of key partners.

China's share has more than doubled, making it the EU's largest radiator supplier

Chinese exports of radiators to the EU grew from €125 million in 2015 to €294 million in 2025—an increase of 134.5%. China is now by far the EU's largest import source, accounting for approximately 44.6% of total imports by value in 2025 (derived from the €294M Chinese figure against a total import bill of €659M). This growth trajectory accelerated after 2020, coinciding with China's broader expansion in automotive component exports globally.

South Korea and the United States have lost ground

Korean radiator exports to the EU collapsed from €106 million to just €26 million (−75.0%), while US exports fell from €33 million to €12 million (−63.9%). These declines may reflect the reorientation of Korean and American production toward their home or regional markets, increased cost competition from Asia, or shifts in OEM sourcing strategies. Korea's volatility coefficient (0.44) is among the highest of the EU's major partners, suggesting persistent instability in this trade corridor.

Emerging suppliers—Turkey and India—have more than doubled their presence

Turkey and India have emerged as significant and growing suppliers. Turkish exports to the EU rose from €20 million to €47 million (+140.8%), while Indian exports grew from €19 million to €43 million (+127.1%). These gains likely reflect the expansion of automotive manufacturing capacity in both countries, supported by cost advantages and, in Turkey's case, proximity to the EU market and existing customs union arrangements for industrial goods.

Import concentration has increased markedly

The import concentration index (HHI) rose from 1,597 in 2015 to 2,583 in 2025 (+61.7% by value; +98.6% by volume). In value terms, an HHI of 2,583 indicates a moderately concentrated market, with China alone accounting for a dominant share. This increasing concentration raises potential supply-chain resilience concerns, particularly given the net import reliance dynamics discussed in Section 3.

3. Intra-EU Production Has Grown but Is Concentrated in Central Europe

While external trade has expanded, the EU has simultaneously ramped up domestic production of radiators. Production volumes grew by 74.7% over the period, and the EU has transitioned from marginal import dependence to being a clear net exporter in value terms. Within the bloc, the production and export base has shifted eastward, with Poland emerging as the standout performer.

EU production volumes have increased substantially

According to production data, EU production of radiators (measured by number of items) grew from 91.6 million units in 2015 to 160.0 million in 2025 (+74.7%), with a peak of 185.9 million units recorded during the period. Production value rose from €2.29 billion to €2.80 billion (+22.1%). The sharper growth in unit volumes than in value—mirroring the export-side pattern—suggests that EU manufacturers have expanded capacity in standardised product segments, possibly in response to rising demand from new vehicle platforms and the growing complexity of thermal management systems in electric vehicles.

The EU has shifted from near-zero import reliance to a clear net exporter

The net import reliance indicator moved from +0.3% in 2015 (marginally import-dependent) to −16.0% in 2025 (clearly export-oriented). This transformation was driven by the combination of growing exports and rising export propensity, which surged from 12.2% to 37.9% (+211%). Trade intensity likewise doubled from 21.9% to 50.0%, indicating that the EU radiator sector has become significantly more integrated into global markets.

Poland has become the EU's most specialised radiator exporter

The specialisation analysis for 2025 reveals that Poland, Slovakia, and Czechia are the most specialised EU producers and exporters of motor vehicle radiators (RSCA values of 0.61, 0.61, and 0.57 respectively). Poland's position is particularly striking: it went from €30 million in exports in 2015 to €134 million in 2025 (+349.1%), while its imports also grew from €44 million to €102 million (+134.3%). On the import side, Slovakia recorded the largest proportional increase (+441.3%, from €14 million to €76 million), likely reflecting the growth of the Slovak automotive industry—Slovakia is the world's largest car producer per capita—and the associated demand for imported radiator components.

Germany remains the EU's largest radiator exporter (€356 million in 2025), but its growth has been nearly flat (+1.7%). This stagnation, combined with the explosive growth of Poland and the strong performance of France, Spain, and Italy, suggests a gradual geographic diversification of the EU's radiator export base away from its traditional German core.

Geopolitical shocks have reshaped key trade corridors

Two significant supply shocks stand out in the data:

1. UK import price shock (2021): An abnormal price shift of −24.6% was detected in imports from the United Kingdom in 2021, with an abnormality score of 60.2. This coincides with the first year of post-Brexit trade implementation, when new customs procedures and rules of origin came into effect. The UK accounted for 18.4% of EU radiator import value at the time, amplifying the market impact.

2. Russian export supply collapse (2025): EU exports to the Russian Federation fell by −94.2% (from €33.5 million in 2015 to €3.3 million in 2025), with the most dramatic decline occurring after 2022, reflecting the impact of EU sanctions and corporate withdrawals following Russia's invasion of Ukraine. Russia's trade coefficient of variation (0.73) is the highest among all EU export partners, confirming persistent volatility.

The United Kingdom remains the EU's largest single export destination (€240 million in 2025, +57.8%), while Mexico has emerged as a fast-growing market (€105 million, +374.1%), reflecting the increasing integration of EU automotive suppliers into North American production networks.

Conclusion

The EU market for motor vehicle radiators (CN 870891) has undergone substantial transformation over the 2015–2025 period. While the EU has maintained and even strengthened its position as a net exporter—moving from near-zero import reliance to a net export surplus of approximately 16% of production value—the underlying dynamics are more nuanced than the headline figures suggest.

Three structural shifts define the decade. First, import sourcing has consolidated around China, whose exports to the EU more than doubled, while traditional suppliers such as South Korea and the United States have retreated. Second, the EU's export growth has been driven almost entirely by rising unit prices rather than volume, suggesting a shift toward higher-value product segments, even as import prices have declined—widening the gap between what the EU sells and what it buys. Third, the production and export base within the EU has migrated eastward, with Poland, Slovakia, and Czechia emerging as specialised and fast-growing centres, while Germany's dominance has plateaued.

The rising import concentration (HHI up 61.7%) and the growing volume gap between imports and exports present both opportunities and risks. On one hand, the EU's increasing trade intensity and export propensity signal a sector that is successfully competing in global markets. On the other hand, heavy reliance on Chinese supply introduces vulnerability, particularly as geopolitical tensions and trade policy uncertainty continue to evolve. The sector's resilience will depend on the EU's ability to sustain its price competitiveness in higher-value segments while diversifying its import sources and deepening the Central European production cluster that has emerged as its new industrial backbone.
