Market evolution: Engine air filters (CN 842131) — 2015–2025

Introduction

This report analyzes the evolution of the European Union's external trade in intake air filters for internal combustion engines (Customs code 842131) from 2015 to 2025. The EU's trade in this sector has been characterized by strong, export-led growth and a significant strengthening of its net trade position. Key dynamics include a shift in major trading partners, the increasing integration of Central and Eastern European members into production, and a marked rise in the EU's export propensity, indicating a growing role as a global supplier.

1. Strong, export-driven growth and a widening trade surplus

The EU's trade in engine air filters over the period demonstrates robust expansion, with exports growing significantly faster than imports, leading to a more than threefold increase in the trade surplus.

Overall trade value expanded substantially

Total EU trade value showed strong growth. Exports increased by 76.4% (from €385.8m to €680.5m), outpacing import growth of 35.5% (from €278.2m to €376.9m). This dynamic directly resulted in a substantial widening of the trade surplus from €107.6m to €303.5m.

Growth was propelled by rising unit values, especially in exports

The increase in trade value was not solely volume-driven. For exports, quantity grew by 40.0%, but the average price per tonne rose by 25.9%, indicating higher-value product flows or inflationary pressures. Similarly, import quantity grew modestly by 8.3%, while the average import price climbed by 25.1%, reflecting increased sourcing costs.

2. Shifting partner dynamics and geopolitical realignments

The landscape of the EU's main trading partners for engine air filters underwent a notable transformation, characterized by the rise of Asian suppliers and a major realignment in European export destinations.

China consolidated its position as the top import source, displacing the UK

Among the EU's top seven import partners, China more than doubled its exports to the EU (+107.4%), becoming the largest supplier by 2025. In contrast, imports from the United Kingdom fell by 36.9%, likely reflecting post-Brexit trade friction. Other emerging suppliers like Tunisia (+132.4%) and Bosnia and Herzegovina (+539.6%) saw explosive growth.

Export destinations reshaped, with the UK becoming the top market

The export landscape saw the United Kingdom surge to become the EU's primary export market (+100.2%). Exports to Türkiye grew remarkably (+138.7%). A clear geopolitical shock is visible in the collapse of exports to the Russian Federation (-85.1%). Meanwhile, emerging markets like Ukraine (+266.7%) and South Africa (+156.2%) became increasingly important destinations.

3. Increasing internal specialization and trade integration

Behind the top-line trade figures, the EU's internal production structure and engagement with the global market have deepened, with certain member states specializing heavily and the bloc as a whole becoming more trade-integrated.

Production concentrated in specialized, often Eastern European, member states

Production data reveals a clear pattern of specialization. In 2025, the most specialized EU producers (measured by Revealed Symmetric Comparative Advantage, RSCA) were Czechia, Poland, and Slovenia. These countries likely host significant manufacturing clusters serving the European automotive industry.

Trade concentration diversified while production volumes soared

The concentration of imports (HHI by value) decreased by 21.3%, indicating a more diversified sourcing strategy. Concurrently, EU production volumes nearly doubled, growing by 94.2% from 194.9 million to 378.4 million items, significantly outpacing the growth in trade quantities. This suggests EU production became more export-oriented.

The EU's role shifted from net importer to net exporter, with high trade intensity

The most striking metric is the net import reliance, which swung from +1.0% in 2015 to -21.0% in 2025. This confirms the EU transformed from a slight net importer to a significant net exporter. Furthermore, export propensity surged from 12.3% to 41.5%, indicating that a much larger share of EU production is now destined for external markets.

Conclusion

Over the 2015–2025 period, the EU's market for engine air filters (CN 842131) evolved decisively toward a position of competitive strength. The bloc capitalized on its production base, particularly in specialized Eastern European member states, to drive export-led growth that outpaced import expansion, resulting in a vastly improved trade surplus. The trade landscape was reshaped by geopolitical factors, notably the UK's re-emergence as the top export market post-Brexit, the collapse of trade with Russia, and the growing import reliance on China. Underpinning these shifts was a fundamental strategic change: the EU moved from being a marginal net importer to a decisive net exporter, with its industry becoming far more oriented toward global markets.
