Market evolution: Motor vehicle gear boxes (CN 870840) — 2015–2025

Introduction

This report examines the trade dynamics of the European Union in motor vehicle gearboxes and parts (Combined Nomenclature code 870840) over the period 2015–2025. This product category encompasses complete gearboxes as well as their components for tractors, passenger vehicles, goods vehicles, and special-purpose motor vehicles. It is a critical segment of the European automotive supply chain, reflecting broader trends in manufacturing competitiveness, trade diversification, and geopolitical disruption.

Over the decade, the EU consolidated its position as a major net exporter of gearboxes while simultaneously experiencing a dramatic reorientation of both its supplier base and its export destinations. Trade volumes grew on the import side, export unit values rose sharply, and several geopolitical shocks — most notably the post-2022 sanctions on Russia — reshaped the map of trade flows. EU production of gearboxes also expanded substantially, particularly in Central and Eastern European member states.

1. Rising values, shifting volumes: a market that grew in revenue rather than tonnage

1.1 EU exports remained strong in value despite declining physical volumes

Between 2015 and 2025, EU exports of gearboxes grew from €9.73 billion to €10.93 billion in value terms, an increase of 12.3%. However, export volumes actually fell by 11.4%, from 583,144 tonnes to 516,433 tonnes. The peak export value of €12.46 billion was reached in 2022, after which a slight correction occurred. The disconnect between value and volume is explained entirely by a sharp rise in export unit values — from €16,693/tonne in 2015 to €21,161/tonne in 2025, an increase of 26.8%. This indicates that the EU has been moving up the value chain, exporting fewer physical units but at significantly higher prices per tonne — likely reflecting a shift toward more technologically advanced gearbox components, electric drivetrain parts, and higher-margin products.

1.2 EU imports grew faster in both volume and value

On the import side, the trajectory was different. Import values rose from €3.71 billion to €4.99 billion (+34.5%), while import volumes grew from 309,359 tonnes to 396,648 tonnes (+28.2%). Unlike exports, the import unit price increase was modest at +4.9% (from €11,996/tonne to €12,580/tonne). This suggests that the EU has been sourcing more physical gearbox components from abroad, but at relatively stable prices — consistent with importing standardized or mid-range components, particularly from Asian suppliers where cost competitiveness is a key factor.

1.3 The EU's trade surplus held firm, supported by large unit-price differentials

Despite the faster growth of imports, the EU maintained a comfortable trade surplus throughout the period — standing at €5.94 billion in 2025, only marginally below the €6.02 billion recorded in 2015. The surplus peaked at €7.24 billion in 2021. The persistent gap between export and import unit prices (€21,161/tonne vs. €12,580/tonne in 2025) underscores the EU's competitive advantage in higher-value gearbox segments. The net import reliance ratio deepened from −22.3% to −63.7%, confirming a strengthening net-exporter position.

2. A dramatic reorientation of trade partners: the rise of Asian suppliers and the collapse of Russia

2.1 China and India emerged as the fastest-growing import sources

The most striking structural change on the import side has been the surge of Asian suppliers. Chinese gearbox imports into the EU grew by an extraordinary 817%, from €151 million in 2015 to €1.38 billion in 2025, making China the third-largest supplier by value. India showed similarly dramatic growth of 772%, rising from €34 million to €293 million. South Korea also expanded significantly (+55.1%), reaching €627 million. These trends reflect the maturation of Asian automotive component industries and their increasing integration into European supply chains, likely driven by cost competitiveness, expanding production capacity in Asia, and the needs of European OEMs for diversified sourcing.

2.2 Traditional Western suppliers lost ground

In contrast, imports from the United States fell by 42.1% (from €750 million to €435 million), and imports from the United Kingdom declined by 42.6% (from €369 million to €212 million). Japan — the EU's single largest gearbox supplier throughout the period — saw only marginal growth of 0.9%, suggesting market share erosion in relative terms. These shifts likely reflect structural changes in global automotive production, including the relocation of manufacturing capacity and the growing competitiveness of Asian producers. The UK decline may also partly reflect post-Brexit trade frictions.

2.3 The collapse of EU gearbox exports to Russia stands out as the decade's most dramatic shock

On the export side, the most dramatic development has been the near-total collapse of EU exports to the Russian Federation. From €359 million in 2015, exports to Russia fell to just €2 million in 2025 — a decline of 99.5%. The sharpest drop occurred between 2021 and 2022, consistent with the EU sanctions imposed following Russia's invasion of Ukraine. The coefficient of variation for Russia-bound exports was 0.75, the highest among all EU export partners, reflecting the severity of this disruption. This shock was detected as the most significant supply shock in the dataset, with an abnormality score of 2.7 and a shift of −97.8%.

2.4 Mexico and Türkiye absorbed part of the redirected export capacity

The EU successfully redirected some of its export capacity toward other markets. Exports to Mexico more than doubled (+111.4%), growing from €446 million to €943 million, likely reflecting the expansion of European automotive assembly in Mexico. Exports to Türkiye grew by 84.7% (from €616 million to €1.14 billion), and exports to Brazil increased by 63.8% (from €188 million to €309 million). China remained the EU's single largest export destination throughout the period at €3.12 billion in 2025, while the United States grew modestly (+5.2%) to €2.20 billion.

2.5 Trade concentration decreased on both the import and export sides

The Herfindahl-Hirschman Index (HHI) for import concentration fell from 2,371 to 2,025 (−14.6%), while export concentration declined from 1,664 to 1,564 (−6.0%). On the import side, the diversification was driven by the rise of China and India alongside continued Japanese supply. On the export side, the decline in concentration reflects the growing importance of secondary markets (Mexico, Türkiye, Brazil) that partially offset the loss of Russia.

3. European production surged, led by Central and Eastern European member states

3.1 EU gearbox production expanded dramatically in both volume and value

The EU's domestic production of gearboxes saw remarkable growth over the decade. Production quantity increased by 373.9%, from 60 million units to 284 million units, while production value grew by 118.4%, from €8.54 billion to €18.65 billion. The fact that volume growth far outpaced value growth implies that average unit production values actually declined — a pattern consistent with the EU expanding production of standardized gearbox components (particularly for electric and hybrid vehicles that may use simpler transmission systems) while maintaining or growing its high-value exports.

3.2 Romania and Slovakia emerged as the most specialised gearbox producers within the EU

In 2025, the most specialised EU member states in gearbox production were:

Romania and Slovakia stand out for their high Revealed Symmetric Comparative Advantage (RSCA) scores, indicating strong specialisation relative to their overall export profiles. This is consistent with the well-documented trend of gearbox manufacturing relocating to Central and Eastern Europe, where labour costs are lower and proximity to Western European assembly plants provides logistical advantages.

3.3 Germany remained the dominant producer and exporter, but Central European states are gaining share

Germany accounted for 35.7% of total EU gearbox production value in 2025, confirming its role as the sector's anchor. German exports of gearboxes grew from €7.34 billion to €8.37 billion (+14.0%). However, the data on intra-EU import flows shows that several Central European states dramatically increased their imports — Slovakia's imports grew by 203.7% (from €180 million to €547 million), and the Netherlands saw an 851.8% increase (from €78 million to €742 million), the latter likely reflecting the role of Rotterdam as a logistics hub for re-export. Germany itself remained the largest importer within the EU at €1.30 billion, up 5.5%.

Notably, Spain's extra-EU exports grew by 127.9%, while France (−32.7%) and Belgium (−61.6%) saw significant declines, reflecting possible shifts in production footprints and the competitive repositioning of the Spanish automotive sector.

3.4 The product mix shifted: gearbox parts gained ground at the expense of industrial-assembly gearboxes

Looking at the subheading breakdown, the import of complete gearboxes (87084050) remained the dominant category but saw volume peaking around 2023 before declining to 219,597 tonnes in 2025. Imports of general gearbox parts (87084099) grew steadily from 92,172 tonnes to 116,674 tonnes (+26.6%). In contrast, imports of gearboxes for industrial assembly (87084020) — which cover specific engine-capacity thresholds — collapsed by 46.9% in volume (from 84,221 tonnes to 44,732 tonnes), likely reflecting the transition away from the specific internal-combustion engine configurations they cover. On the export side, complete gearboxes (87084050) remained dominant at 411,645 tonnes but declined from the 2017 peak of 497,000 tonnes, consistent with the overall volume decline noted above.

Conclusion

Over the period 2015–2025, the EU gearbox sector evolved along several reinforcing trajectories. The EU consolidated its position as a major net exporter, with trade surplus deepening to −63.7% net import reliance and export unit values rising by 26.8% — evidence of a strategic move toward higher-value, more technologically sophisticated products. At the same time, EU domestic production surged by 374% in quantity, driven heavily by Central and Eastern European member states such as Romania and Slovakia that have become specialised manufacturing hubs.

The supplier landscape was transformed by the rise of China (+817%) and India (+772%) as import sources, displacing traditional Western suppliers like the United States and the United Kingdom. On the export side, the single most disruptive event was the collapse of EU–Russia trade after 2022, which eliminated nearly €360 million in annual exports. The EU demonstrated resilience by redirecting flows to Mexico, Türkiye, and Brazil, and by diversifying its supplier base, as evidenced by declining HHI concentration indices on both sides.

Looking ahead, the sector faces a structural question: how will the ongoing electrification of the automotive industry — which typically requires simpler or different transmission systems — affect the long-term demand for traditional gearbox components? The sharp decline in imports of industrial-assembly gearboxes (−47% by volume) may be an early signal of this transition, even as overall production volumes continue to rise.
