Market evolution: Road wheels (CN 870870) — 2015–2025

Introduction

This report examines the evolution of EU external trade in road wheels and their parts and accessories (Combined Nomenclature code 870870) over the period 2015–2025. The product scope covers aluminium road wheels, cast iron or steel wheel centres, and a broad residual category of road wheels destined for tractors, passenger cars, buses, goods vehicles, and special-purpose motor vehicles. Over the eleven-year window, the EU's position in this market underwent a fundamental transformation: the bloc shifted from a marginal net exporter to a substantial net importer, with the trade deficit widening from €28 million in 2015 to €878 million in 2025. This structural reversal was driven by a combination of surging imports—particularly from Türkiye and Morocco—stagnating export volumes, sharp price escalation in aluminium wheels, and significant geopolitical disruptions that re-drew supply chains after 2020. The following sections trace these dynamics in detail.

1. A Reversal of Fortunes: The EU's Slide into Net Import Dependence

The headline trade balance deteriorated dramatically

The most striking feature of the 2015–2025 period is the EU's transition from near-balance to deep deficit in road wheels. In 2015, imports stood at €1.46 billion against exports of €1.43 billion, yielding a modest deficit of €28 million. By 2025, imports had climbed to €2.39 billion while exports reached only €1.51 billion, producing a deficit of €878 million—a deterioration of over 3,000%. The net import reliance ratio confirms this swing: it moved from −13.8% in 2015 (indicating the EU was a net supplier to world markets) to +12.1% in 2025 (indicating net dependence on external sources).

Import growth outpaced exports in both value and volume

Imports grew by +63.8% in value (from €1.46 billion to €2.39 billion) and by +32.2% in volume (from 381,048 t to 503,896 t). By contrast, exports rose by only +5.7% in value (from €1.43 billion to €1.51 billion) while their volume fell by −26.2% (from 251,079 t to 185,361 t). The EU thus sold fewer tonnes abroad at higher prices, while simultaneously importing far more tonnes at moderately higher prices.

Unit-price divergence reveals a premiumisation of EU exports

A key mechanism behind the value-volume divergence is the divergence in unit prices. EU export prices rose by +43.2% (from €5,706/t to €8,169/t), while import prices rose by only +23.9% (from €3,833/t to €4,747/t). This growing price gap—from €1,873/t in 2015 to €3,422/t in 2025—suggests that the EU increasingly exports higher-value, specialty wheels (notably aluminium alloy wheels from premium manufacturers) while importing lower-cost, mass-market wheels. The trade intensity index rose from 41.4% to 52.6%, confirming that the EU road-wheel sector became significantly more intertwined with global markets over the decade.

2. Shifting Geographies: New Supply Hubs Replace Traditional Partners

Türkiye consolidated its position as the dominant supplier

The single most important partner trend in EU road-wheel imports is the rise of Türkiye. Turkish suppliers grew their shipments from €575 million in 2015 to €1.08 billion in 2025 (+86.9%), making Türkiye the source of roughly 45% of all EU road-wheel imports by value. Türkiye's low volatility (coefficient of variation of 0.13) underscores the structural, not cyclical, nature of this dominance—it reflects long-standing integration between Turkish wheel manufacturers and European OEM assembly lines, as well as cost advantages from a depreciating lira.

Morocco emerged from near-zero to become a major supplier

Perhaps the most dramatic shift is Morocco, which went from exporting a negligible €142,586 worth of road wheels to the EU in 2015 to €287 million in 2025—a growth of over 200,000%. This explosive ramp-up reflects the broader relocation of automotive manufacturing to Morocco (e.g., the Renault Tangier and SOMACA Casablanca plants), which has attracted a growing ecosystem of tier-1 and tier-2 component suppliers. However, Morocco's import coefficient of variation is very high (1.14), indicating that this supply relationship is still volatile and may be concentrated in a small number of facilities or contracts.

Korea collapsed as a supplier while China and Thailand gained

South Korean imports to the EU fell by −94.0%, from €172 million in 2015 to just €10 million in 2025. This collapse likely reflects a combination of Hyundai-Kia's increased localisation of production within Europe (particularly in the Czech Republic and Slovakia) and a shift toward sourcing from lower-cost Asian platforms. Meanwhile, China (+106.4%, from €161 million to €332 million) and Thailand (+36.3%, from €92 million to €125 million) expanded their presence, pointing to broader diversification of Asian supply.

EU exports lost Russia but gained in North America and Western Europe

On the export side, the most dramatic shift was the near-total collapse of EU exports to Russia—from €99 million in 2015 to €1.6 million in 2025 (−98.4%). This is almost certainly a consequence of EU sanctions following Russia's invasion of Ukraine in 2022; Russia's export coefficient of variation (0.75) reflects the sharp, policy-driven disruption. Meanwhile, the United States grew from €162 million to €282 million (+73.9%), and Norway nearly doubled from €75 million to €149 million (+98.1%). The United Kingdom, however, remained the EU's largest single export market despite declining by −32.8% (from €494 million to €332 million)—a drop that likely reflects both post-Brexit frictions and the UK's own efforts to develop localised supply chains.

Import concentration increased while export markets diversified

The Herfindahl-Hirschman Index (HHI) for imports rose from 1,979 to 2,452 (+23.9%), moving the EU's import base closer to the "highly concentrated" threshold. This reflects the growing dominance of Türkiye. On the export side, the HHI fell from 1,541 to 1,139 (−26.1%), indicating that EU exporters successfully diversified away from their former dependence on the UK and Russia toward a broader set of destinations.

3. Prices, Product Mix, and the Aluminium Wheel Premium

Aluminium wheels dominate both imports and exports and drove price inflation

The product segment breakdown reveals that aluminium road wheels (subheading 87087050) are by far the largest category. In 2025, they accounted for €1.72 billion of the €2.39 billion in imports (72%) and €1.08 billion of the €1.51 billion in exports (71%). Over the period, aluminium wheel imports grew by +80.3% in value (from €955 million to €1.72 billion) and +50.3% in volume (from 197,637 t to 297,115 t). Aluminium wheel exports grew by +17.1% in value (from €921 million to €1.08 billion) despite a −15.4% volume decline (from 117,517 t to 99,359 t).

The unit-price trajectory is revealing. EU export prices for aluminium wheels rose from €7,840/t in 2015 to €10,862/t in 2025 (+38.4%), while import prices for the same subcategory rose from €4,832/t to €5,798/t (+20.0%). The export-import price premium for aluminium wheels thus widened from €3,008/t to €5,064/t, suggesting that EU manufacturers increasingly focus on premium, large-diameter, and design-intensive alloy wheels for luxury and performance vehicles—products where European brands (e.g., BBS, Ronal, Maxion-Rütschi) retain a competitive edge.

The "other" category and industrial-assembly wheels showed divergent paths

The residual category (87087099, covering non-aluminium, non-star-form wheels) experienced a sharp decline in export volumes (−37.4%, from 111,963 t to 70,054 t) and value (−16.5%, from €434 million to €362 million), though its export price rose by +33.3% (from €3,876/t to €5,169/t). On the import side, this category grew by +54.7% in value (from €323 million to €500 million) and +29.2% in volume.

The industrial-assembly subheading (87087010), which covers wheels destined for CKD/SKD vehicle assembly, remained relatively flat in imports (−4.7% in value, from €158 million to €151 million; −14.9% in volume) and declined in exports (−10.7% in value). This stagnation may reflect the general trend toward more integrated global platforms where wheel sourcing is decentralised. The cast-steel star-form wheel centres (87087091) remain a niche product, accounting for less than 1% of trade by value; import volumes in this subcategory collapsed by −68.4%.

EU production value rose even as volumes declined, mirroring the trade pattern

Domestic EU production data show a pattern consistent with the trade figures: production value grew by +55.3% (from €3.09 billion to €4.80 billion) while physical output fell by −18.3% (from 1.39 billion kg to 1.14 billion kg). This implies that the average unit value of EU-produced wheels roughly doubled over the decade, further evidence that European manufacturing has shifted toward higher-value products while leaving the volume-intensive, lower-margin segment to imports.

Shock events in 2021–2022 reflect broader supply-chain disruptions

The shock detection analysis identifies three notable events. First, a price shock in EU exports to the United States in 2022, with a +30.5% price shift and an abnormality score of 18.3, likely reflecting post-pandemic demand surges and supply tightness in the North American auto sector. Second, a price shock in imports from Türkiye in 2022 (+36.1% shift, abnormality 8.9), coinciding with Turkey's domestic inflation crisis and lira depreciation, which raised the euro-denominated cost of Turkish inputs. Third, a price shock in UK-sourced imports in 2021 (−13.6% shift, abnormality 8.7), possibly linked to post-Brexit adjustment and sterling fluctuations. These shocks underline the sensitivity of the EU road-wheel trade to macroeconomic and geopolitical events.

Central and Eastern European member states are the EU's most specialised producers

The specialisation analysis for 2025 shows that the EU member states with the highest revealed comparative advantage in road-wheel exports are Luxembourg (RSCA 0.80), Hungary (0.46), Poland (0.34), Czechia (0.27), and Austria (0.25). These countries host major automotive and wheel manufacturing clusters—Hungary and Poland in particular have attracted significant foreign direct investment in aluminium wheel foundries and finishing lines. Germany, while not among the most specialised, remains the largest absolute exporter (€591 million in 2025) and importer (€820 million), reflecting its role as the EU's automotive hub with massive two-way flows. Czechia stands out for its import growth of +252.1% (from €46 million to €160 million), consistent with the expansion of Škoda and Hyundai production requiring ever-larger component inflows.

Conclusion

Over the period 2015–2025, the EU road-wheel market (CN 870870) underwent a structural transformation. The bloc moved from rough trade balance into a pronounced import dependence, driven by a 64% increase in import value against a near-stagnation of exports. This was not simply a volume story: unit prices rose across the board, but EU export prices rose nearly twice as fast as import prices (+43% versus +24%), pointing to a strategic repositioning of European manufacturers toward premium aluminium wheels while ceding the mass market to imports.

Geographically, the trade map was redrawn. Türkiye consolidated its lead as the EU's primary wheel supplier, Morocco surged from obscurity to a €287 million supplier, and China doubled its share. On the export side, Russia vanished as a destination following sanctions, while the US and Norway gained importance. Import concentration rose, raising questions about supply-chain resilience—particularly given that Türkiye now accounts for nearly half of all imports.

These trends carry important implications. The growing trade deficit and rising import concentration suggest that the EU's strategic autonomy in a critical automotive component is eroding. At the same time, the premiumisation of EU exports and domestic production indicates that European manufacturers retain competitiveness in high-value segments. Policymakers and industry stakeholders should monitor whether the current trajectory—volume migrating outward, value concentrating at the top—proves sustainable, or whether it presages a deeper hollowing-out of the EU's road-wheel industrial base.
