Market evolution: Oil and fuel filters (CN 842123) — 2015–2025

Introduction

This report analyses the evolution of the European Union's external trade in oil and petrol filters for internal combustion engines (Combined Nomenclature code 842123) over the period from 2015 to 2025. The analysis is based on annual trade data encompassing value, volume, and unit prices, with a focus on the EU's major trade partners and underlying market structures. Over the decade, the EU market for this product category has undergone a significant transformation, characterized by robust export growth, a diversification of trading relationships, and a strengthening of the Union's competitive position, culminating in a major shift in its trade balance.

I. A Decade of Export-Led Growth and a Reversed Trade Balance

The most striking development in the EU's trade for CN 842123 is the dramatic expansion of exports, which has outpaced import growth and fundamentally altered the Union's net trade position.

EU exports grew substantially in both value and price

EU exports surged from EUR 980 million in 2015 to EUR 1.65 billion in 2025, representing a 68.2% increase in value. This growth was not primarily volume-driven; export quantity rose more modestly by 13.6% over the period. The dominant driver was a 48.1% increase in the unit export price, from EUR 13,732 per tonne to EUR 20,333 per tonne. This indicates a successful shift towards higher-value-added products or enhanced pricing power in foreign markets. More details on the overall trade overview can be found here.

Import growth was solid but lagged behind exports

EU imports also grew, from EUR 550 million to EUR 802 million (+45.9%). The growth in import volume was more pronounced than for exports (+25.6%), while import prices increased by 16.1%. The differential growth rates between exports and imports led to a fundamental change in the EU's trade balance.

The EU transformed from a moderate net exporter to a strong one

The EU's trade balance with the rest of the world improved dramatically, moving from a surplus of EUR 430 million in 2015 to a surplus of EUR 846 million in 2025, a near-doubling (96.6% increase). Consequently, the net import reliance metric, which was already negative at -15.6% in 2015, deepened to -103.9% by 2025. This confirms that the EU has become a significant net exporter of these filters, with its exports now far exceeding its imports.

II. Geographic Diversification and Shifting Trade Corridors

The expansion of EU trade was accompanied by a notable reorientation of its import and export partnerships, with varying degrees of growth and volatility among key countries.

EU imports diversified away from traditional partners towards emerging economies

The top import partners show a clear trend. While China remained the largest single source, its share grew by 51.9% to EUR 212 million. The most explosive growth came from Tunisia (+170.1% to EUR 91 million) and Türkiye (+164.2% to EUR 60 million), which rose to become the third and fourth largest suppliers. Conversely, imports from the United Kingdom and the United States showed relatively modest or negative growth.

EU exports grew strongly to key markets but collapsed to Russia

EU export destinations witnessed even more dramatic shifts. The United States became the primary destination, with exports more than doubling (+107.3%) to EUR 254 million. Exports to Türkiye surged by 169.5% to EUR 167 million. In stark contrast, exports to the Russian Federation plummeted by 86.3%, from EUR 86 million to just EUR 12 million, likely reflecting geopolitical and sanctions-related disruptions. Meanwhile, exports to Brazil (+181.4%) and the United Arab Emirates (+100.2%) also saw exceptional growth.

Trade concentration remained low, indicating a diversified market

The Herfindahl-Hirschman Index (HHI) for import value fell from 1,415 to 1,239, while for exports it slightly decreased from 703 to 668. Both values remain below 1,500, suggesting a competitive market with no extreme dependence on any single foreign partner.

III. Internal Production Boom, Specialization, and Selective Supply Shocks

Behind the trade figures, the EU's domestic production of filters expanded massively, cementing its competitive edge. However, the market also faced notable supply-side volatility.

EU production volumes tripled, driving export capacity

Based on Prodcom data, EU production quantity surged from 371 million items in 2015 to an estimated 1.14 billion items in 2025, a 207.5% increase. The value of production also grew strongly by 80.8% to EUR 1.47 billion. This massive ramp-up in domestic manufacturing capacity is the fundamental enabler of the EU's transformed role as a net exporter.

Eastern European Member States showed the highest export specialization

Analysis of revealed comparative advantage (RCA) for 2025 highlights a clear geographic pattern within the EU. Bulgaria, Czechia, Poland, and Slovenia exhibited the highest RSCA (Balassa) scores, indicating they are most specialized in exporting this product category relative to other EU members. Conversely, Ireland, Denmark, and Portugal showed low specialization, likely focusing on other sectors.

Trade with some partners exhibited high volatility and specific shocks

The coefficient of variation reveals that trade with certain partners was highly unstable. Morocco had the most volatile import relationship (CV=0.65), while exports to Russia were highly erratic (CV=0.45). Specific supply shocks were detected: imports from India experienced a severe price shock in 2023, and exports to Morocco saw a significant price spike the same year, indicating potential supply chain or competitive disruptions.

Conclusion

The period from 2015 to 2025 marked a successful transformation for the EU's oil and fuel filter market. Fueled by a more than tripling of domestic production, the EU evolved from a balanced trader into a formidable net exporter, doubling its trade surplus. This growth was predominantly value-driven, reflecting a move up the value chain. Geographically, the EU diversified its sources, particularly integrating suppliers from North Africa and Türkiye, while its export markets expanded robustly, especially to the United States and Türkiye. The trade balance shift, the surge in production, and the export specialization in several Central and Eastern European economies together paint a picture of a strengthening industrial base. However, this expansion was not without vulnerabilities, as evidenced by the high volatility and isolated supply shocks experienced with specific partners, underscoring the ongoing need for resilient supply chain management.
