Market evolution: Disc brake parts (CN 87083091) — 2015–2025

Introduction

Disc brake parts (CN 87083091) are a critical component within the EU automotive supply chain, falling under the broader category of brakes and servo-brakes for motor vehicles. Over the 2015–2025 period, the EU's external trade in this product category underwent significant structural shifts. Total EU trade flows expanded substantially, but the pace and composition of that expansion differed markedly between exports and imports. While the EU remained a net exporter throughout the decade, the nature of its competitive position evolved, shaped by the rise of Chinese supply, geopolitical disruptions, and shifting production geography within Europe itself. This report examines these dynamics across three main axes: the macro trade trajectory, the changing geography of partners, and the structural implications for EU industrial resilience.

1. Imports surged far faster than exports, yet the EU preserved its net-exporter status

Export values grew steadily, but import values nearly doubled

Between 2015 and 2025, EU exports of disc brake parts to non-EU countries rose from €2.09 billion to €2.87 billion, a gain of 37.4%. Over the same period, imports climbed from €1.02 billion to €1.80 billion — an increase of 76.7%, roughly double the rate of export growth. The trade balance, however, remained broadly stable at around €1.07–1.08 billion, indicating that the EU's export lead, while not expanding in absolute terms, was preserved.

The volume–price decomposition reveals divergent strategies

A key insight lies in the volume–price decomposition. EU export growth was driven significantly by rising unit prices (+25.7%), with quantity growing only modestly (+9.4%). This suggests that EU manufacturers moved upmarket or benefited from inflationary pricing, rather than expanding physical output for export. By contrast, import growth was overwhelmingly volume-driven: physical quantities surged by 62.0% while import prices rose only 9.1%. This points to an influx of lower-cost disc brake parts — particularly from Asia — entering the EU market in ever-greater volumes.

The EU's net import reliance deepened despite remaining negative

The net import reliance indicator, which is negative when the EU is a net exporter, moved from −10.7% in 2015 to −12.3% in 2025. While this confirms the EU's continued net-exporter status, the trajectory is not uniform: the indicator dipped as low as −35.4% at one point (likely during the COVID-era export boom of 2021–2022), before reverting. The trade intensity of the sector increased from 28.4% to 41.2%, and export propensity rose from 20.6% to 30.0%, indicating that the EU disc brake parts industry became significantly more internationally oriented over the decade.

EU production expanded in both volume and value

Domestic production data confirms a robust industrial base. Output in quantity terms grew from 1.59 billion kg to 2.26 billion kg (+41.6%), while production value rose from €8.99 billion to €14.10 billion (+56.8%). The faster growth in value than in quantity points to a product mix shifting toward higher-value components and/or general price inflation in the sector. Despite the surge in imports, EU production remained far larger than the import bill, underscoring the sector's domestic depth.

2. China's rise redrew the import map, while exports diversified toward new growth markets

China became the EU's dominant import supplier, with value growing 155%

The most dramatic shift in the partner geography of EU imports was the ascent of China. Chinese disc brake part shipments to the EU rose from €413 million in 2015 to €1.06 billion in 2025, a 155.2% increase. By 2025, China alone accounted for well over half of all EU imports in this category. Other Asian suppliers grew more modestly: India rose from €75 million to €103 million (+38.7%), while South Korea actually declined from €55 million to €45 million (−17.7%).

Türkiye emerged as a fast-growing dual-direction partner

Türkiye stands out as a partner that grew on both sides. EU imports from Türkiye more than tripled from €34 million to €114 million (+236.6%), while EU exports to Türkiye nearly doubled from €162 million to €290 million (+79.6%). This bilateral intensification likely reflects the deepening integration of Türkiye into European automotive supply chains, serving both as a sourcing platform and a market for higher-specification EU-made components.

Geopolitical shocks reshaped the export map

On the export side, the most striking development was the collapse of exports to Russia. EU disc brake part shipments to Russia fell from €145 million in 2015 to just €20 million in 2025 (−86.2%), almost certainly a consequence of EU sanctions following the 2022 invasion of Ukraine. The volatility coefficient for Russia-bound exports was 0.63, among the highest of any partner, reflecting the abrupt nature of this disruption.

Mexico emerged as the fastest-growing EU export destination

Mexico's import of EU disc brake parts surged by 232.2%, from €58 million to €191 million — the highest growth rate among all major export partners. This likely reflects the expansion of European OEM assembly operations in Mexico and the country's role as a gateway to the North American market. However, a notable price shock was detected in EU exports to Mexico in 2017, with an abnormality score of 12.8 and a unit-price decline of 28.2%, suggesting a temporary disruption or contract renegotiation.

3. Import concentration intensified while Central-Eastern Europe consolidated its role in production

Import sourcing became significantly more concentrated around China

The Herfindahl-Hirschman Index (HHI) for EU imports by value rose from 2,494 in 2015 to 3,805 in 2025, a 52.6% increase. By volume, the HHI climbed even more steeply, from 3,616 to 6,088 (+68.3%). These levels place EU import sourcing firmly in the "highly concentrated" territory, driven overwhelmingly by China's expanding share. This increasing concentration represents a growing dependency risk: a disruption to Chinese supply — whether from trade policy, logistics, or geopolitical events — would have a disproportionately large impact on the EU automotive sector.

Export diversification moved in the opposite direction

In contrast, the export HHI declined from 991 to 840 (−15.3% by value, −20.3% by volume). This indicates that EU exporters successfully diversified their destination markets over the decade. The loss of the Russian market was offset by gains in Mexico, Türkiye, Morocco, and other non-traditional destinations, resulting in a healthier, less concentrated export portfolio.

Central and Eastern European members emerged as specialised production hubs

The specialisation analysis for 2025 reveals a clear Central-Eastern European (CEE) cluster of highly specialised disc brake part producers. Slovakia (RSCA: 0.54, RCA: 3.37), Poland (RSCA: 0.52, RCA: 3.14), and Czechia (RSCA: 0.38, RCA: 2.23) all display strong revealed comparative advantages in this product. Germany, while the largest absolute exporter (€1.43 billion in 2025), shows a more moderate specialisation index (RSCA: 0.17), reflecting its diversified industrial base.

Poland and Czechia experienced explosive growth on both trade and production

Among EU reporting members, Poland and Czechia stand out for their rapid expansion in both imports and exports. Polish imports grew by 298.1% (from €60 million to €240 million) and exports by 198.6% (from €74 million to €221 million). Czech imports grew by 53.0% and exports by 204.9%. These countries have become key nodes in the European disc brake parts value chain, importing components (often from Asia) for integration into locally assembled brake systems that are then exported both within and outside the EU. Italy also showed strong export growth (+90.8%), rising to €317 million, suggesting a reinvigoration of its automotive component sector.

German dominance persisted but the broader EU production base shifted eastward

Germany remained the EU's largest exporter of disc brake parts, accounting for approximately 30% of production value in 2025 and 50% of extra-EU exports. However, the combined CEE share (Poland, Czechia, Slovakia, Romania) grew substantially over the decade, reflecting the ongoing relocation of automotive component manufacturing toward lower-cost EU member states with established industrial infrastructure. Romania's exports, however, declined by 38.2% (from €94 million to €58 million), suggesting some instability or restructuring in its role within the supply chain.

Conclusion

The EU's trade in disc brake parts (CN 87083091) over 2015–2025 tells a story of a sector that remained internationally competitive but faced mounting structural shifts. The EU preserved its net-exporter status and saw its production base grow robustly, with output value rising by nearly 57%. However, the import side underwent a fundamental transformation: China's share surged dramatically, driving a 52.6% increase in import concentration and creating a pronounced supplier dependency. On the export side, the loss of the Russian market — a direct consequence of geopolitical conflict — was more than compensated by rapid growth in Mexico, Türkiye, and other emerging destinations, resulting in a more diversified export portfolio.

The internal geography of EU production also shifted, with Central-Eastern European members — especially Poland, Czechia, and Slovakia — consolidating their positions as specialised, high-growth production hubs. This eastward rebalancing, combined with rising trade intensity (from 28.4% to 41.2%), suggests a sector that is increasingly integrated into global value chains. The key risk going forward is the concentration of import sourcing: with China accounting for over half of extra-EU imports by value, the EU's disc brake parts supply chain is significantly more exposed to single-country disruption than it was a decade ago.
