Market evolution: Fuel oil additives (CN 381190) — 2015–2025

Introduction

This report analyses the trade dynamics of the European Union in oxidation inhibitors, viscosity improvers, and other prepared additives for mineral oils (Customs code 381190) between 2015 and 2025. The data reveals a market in transition, characterized by a significant decline in trade volumes coupled with a substantial increase in unit values. This period saw the EU solidify its position as a major global supplier, with its export performance proving more resilient than its import dependence. The product's scope covers a broad range of specialty chemical additives critical for the fuels and lubricants industry.

A Decade of Divergence: Falling Volumes but Surging Values

The most striking feature of the 2015-2025 period is the divergent movement between the physical quantities traded and their monetary value. The EU experienced a pronounced contraction in trade volumes while the value of that trade, driven by rising prices, remained relatively robust.

The Great Volume Contraction Both EU imports and exports of CN 381190 fell sharply in tonnage terms. Import volumes plummeted by 52.6%, from 80,341 tonnes in 2015 to 38,072 tonnes in 2025. Export volumes also declined substantially, by 32.3%, from 198,074 tonnes to 134,036 tonnes over the same period. This points to a combination of factors likely including efficiency gains in additive use, changes in the composition of demand (e.g., from automotive fuel additives towards industrial applications), and perhaps some degree of regionalization or nearshoring of supply chains post-2020.

Value Resilience Fueled by Price Increases Despite the collapse in volumes, the financial value of this trade did not follow suit. EU export values decreased by only 5.3% (from €525 million to €497 million), while import values fell by 17.9% (from €148 million to €121 million). This resilience is explained by a dramatic rise in unit prices. Average export prices surged by 39.9% (from €2,651/t to €3,708/t), and average import prices rose by an even more striking 73.3% (from €1,838/t to €3,184/t). This inflationary trend reflects increased raw material costs, supply chain disruptions (notably from 2020 onwards), and the growing value-share of higher-specification additives.

The Net Trade Balance: A Story of Strength The EU maintained a consistently large positive trade balance throughout the period, underscoring its role as a net exporter. While the absolute balance in euros saw a slight marginal decline of 0.4%, the structural advantage is clear. In 2025, the EU exported €376 million more worth of these additives than it imported. The net import reliance metric, which was already negative (-8.1%, indicating a surplus) in 2015, deepened significantly to -45.2% by 2025. This indicates the EU's domestic production capacity grew even more dominant relative to its consumption over the decade.

Shifting Geographies: The Reconfiguration of Trade Partners

The network of countries supplying and buying from the EU underwent a profound transformation, reflecting geopolitical shifts and changing competitive landscapes.

The Collapse and Reorientation of Import Sources The United Kingdom, which was the EU's top import source in 2015 (€85.4 million), saw its share collapse by 54.4% to €38.9 million by 2025, likely influenced by Brexit-related trade barriers. A more dramatic collapse occurred with the Russian Federation, where imports fell from €11.1 million to a negligible €11,251—a 99.9% decrease, predominantly due to sanctions following the 2022 invasion of Ukraine. Conversely, new or rising suppliers emerged. India saw its export value to the EU surge by 1,238.5% (from €0.5 million to €7.2 million), and Switzerland's exports grew by 666.7%. The United States remained a stable and significant partner, with exports to the EU rising by 27.7%.

Export Markets: Diversification Amidst Setbacks EU exporters faced a more challenging environment. The Russian Federation, once the second-largest destination (€64 million in 2015), saw a 77.8% drop in imports from the EU by 2025, again due to sanctions. Exports to China and South Africa also fell dramatically (by 58.6% and 48.7%, respectively). However, the EU successfully redirected exports to other markets. Türkiye, the Republic of Korea, and Argentina remained stable or grew as key partners, demonstrating the sector's ability to adapt its trade flows.

Structural Strength: Specialisation and Reduced Concentration

Underpinning the trade performance is a strengthening industrial base within the EU and a more diversified, though still volatile, trading system.

Concentration of Production: The German-Belgian-French Core EU production of CN 381190 additives grew impressively, with output value rising by 131.7% to reach €1.18 billion in the latest data. This production is highly concentrated. Germany is the undisputed leader, accounting for 41.6% of EU export value in 2025, followed by Belgium (22.2%) and France (14.6%). Specialisation analysis confirms this: Belgium and Germany exhibit strong revealed comparative advantage (RCA) in this product category.

Evolving Market Concentration (HHI) The Herfindahl-Hirschman Index (HHI), which measures supplier or buyer concentration, shows a clear trend towards diversification. The HHI for EU imports by value fell by 22.6% from 4,328 to 3,351, indicating that the EU sources its additives from a broader range of countries than in 2015. For exports, the HHI is much lower and also fell by 29.7% (from 478 to 336), meaning EU exports are even more widely distributed across numerous destination countries. This diversification enhances the resilience of the EU's trade network.

Volatility and Shocks in a Changing World Despite the overall positive trends, the market has been subject to significant volatility and shocks. The coefficient of variation for trade with the Russian Federation is extreme (3.22 for imports), highlighting the disruption caused by sanctions. Supply shocks were detected, most notably a major price shock for imports from the United States in 2022 (an abnormality score of 30.6) and for exports to the Republic of Korea. These events, centered around 2022, likely reflect the cascading effects of the energy crisis and broader post-pandemic inflationary pressures on the petrochemical industry.

Conclusion

Over the 2015-2025 decade, the EU's trade in fuel oil additives (CN 381190) has navigated significant headwinds to emerge in a structurally stronger position. While trading fewer tonnes, the bloc has seen the value of its exports protected by rising prices, reflecting a shift towards higher-value products. The most consequential change has been the radical reconfiguration of trade partners, driven by geopolitical events like Brexit and sanctions against Russia. The EU has proven its industrial resilience, with its production capacity growing substantially and its exports becoming more geographically diversified, thereby reducing concentration risks. The market's inherent volatility, however, was laid bare by the price shocks of 2022. Moving forward, the sector's health will depend on its continued innovation, the stability of its (now more diversified) supply chains, and its ability to adapt to the ongoing energy transition.
