Market evolution: Synthetic rubber (CN 4002) — 2015–2025

Introduction

This report analyses the evolution of the European Union's external trade in synthetic rubber and related mixtures (Combined Nomenclature code 4002) over the period 2015-2025. The EU market for this essential raw material, used in industries from automotive to construction, has been shaped by significant shifts in global supply chains, geopolitical events, and internal production dynamics. Overall, the period is characterized by a growing structural trade deficit, increasing price volatility, and a heightened dependency on a reshuffled set of international suppliers. Production within the EU has contracted, while the bloc's integration into global trade has intensified, making it more exposed to external shocks. For a complete overview of the product scope, please refer to the product description.

A Widening Trade Deficit and the Reshuffling of Import Dependencies

The EU's external trade in synthetic rubber shifted from a small deficit in 2015 to a much larger one by 2025. This was driven by divergent trends in import and export values, despite both flows experiencing falling physical volumes.

The Divergence Between Import Values and Volumes

Between 2015 and 2025, the total value of the EU's synthetic rubber imports grew by 12.5%, from €2.08 billion to €2.34 billion. However, this growth in expenditure occurred alongside a 13.3% decrease in imported volume, from 1.11 million tonnes to 0.96 million tonnes. This indicates a significant rise in import unit prices, which increased by 29.8% over the period. The combination of higher prices and lower volumes points to increased costs for EU downstream industries and/or a strategic shift towards higher-value imported products. In contrast, EU exports saw a 6.9% decline in value and a sharper 24.1% drop in volume, with export prices rising by 22.8%. The result was a dramatic widening of the trade deficit in value terms, which grew by 257% from €152 million in 2015 to €544 million in 2025. More details on these aggregate flows can be seen in the general trade overview.

The Collapse of Russian Supplies and the Rise of Asian Partners

The most dramatic shift in the EU's import sources was the collapse of trade with the Russian Federation. Russia was the EU's top supplier by value in 2015 (€560 million), but its share plummeted by 80.4% to just €110 million by 2025. This decline, which accelerated after 2022 due to geopolitical sanctions, created a vacuum that was partially filled by other suppliers. The most notable beneficiary was the Republic of Korea, whose exports to the EU grew by 87.3% (from €168 million to €315 million). Similarly, China expanded its exports to the EU by 253% (from €62 million to €220 million), and Saudi Arabia emerged as a new major supplier, growing from a negligible €27,000 in 2015 to €113 million in 2025. The United States and Japan remained stable, large-scale suppliers. This reshuffling significantly reduced the concentration of import sources, as measured by the Herfindahl-Hirschman Index (HHI), which fell by 28.9% from 1834 to 1304, indicating a more diversified but geographically dispersed supply base. The evolution of these top import partners highlights the EU's strategic reorientation away from Russia.

EU Export Markets: Stability in Key Destinations, Growth in Emerging Ones

EU exports of synthetic rubber were more geographically concentrated and stable than imports, with the top seven destinations accounting for the majority of flows. The United States and China were consistently the largest markets, with relatively flat value growth (-1.1% and -0.4% respectively). Notably, exports to Türkiye grew robustly by 47.2%, and exports to India surged by 67.9%. In contrast, exports to the United Kingdom fell by 18.3% post-Brexit. The concentration of export markets remained low and stable, with the HHI staying near 820 throughout the period. The detailed trends for EU top export partners reveal the resilience of established trade relationships alongside growth in developing economies.

Contraction and Concentration of Intra-EU Production

While external trade intensified, domestic production within the EU experienced a notable contraction, pointing to structural challenges or strategic adjustments within the European synthetic rubber industry.

Falling Production Volumes Amid Stable Value

EU production (in kilograms) of synthetic rubber fell by 37.0% over the period, from approximately 3.99 billion kg in 2015 to 2.52 billion kg in 2025. This indicates a significant reduction in physical output. However, the value of this production declined by a much smaller 2.0%, from €4.77 billion to €4.68 billion. This divergence suggests that European manufacturers shifted their product mix towards higher-value, potentially more specialized synthetic rubber types, or that inflation offset the drop in volume. The production contraction is a key reason for the EU's increasing net import reliance, which grew from 8.1% to 11.7%. The trend in EU production volumes underscores a strategic change in the domestic industrial base.

Specialization and Dominance of Key Member States

Production is highly concentrated among a few EU member states. In 2025, Belgium was the most specialized producer, with a Revealed Symmetric Comparative Advantage (RSCA) of 0.56, indicating a strong export focus in this sector. France (RSCA 0.22) and Hungary (RSCA 0.19) also showed clear specialization. Germany, despite having a lower RSCA (0.02), remained the largest producer in absolute value, accounting for over 22% of EU production. This structure highlights a core of specialized producers (Benelux, France) alongside large, diversified chemical economies (Germany). Conversely, countries like Ireland, Croatia, and Latvia had negligible production shares. The data on specialisation levels reveals the uneven industrial landscape across the bloc.

Price Surges, Supply Shocks, and Rising Vulnerability

The period was marked by extreme price volatility and specific supply disruptions that amplified the EU's external dependency, culminating in the shock year of 2022.

The 2022 Price Spike and Its Systemic Impact

The year 2022 stands out as a period of severe market stress, marked by sharp price shocks across multiple trade relationships. The most significant was the 36.9% price surge in EU imports from the United States, which carried a high abnormality score of 6.2 and accounted for 27.1% of total import value that year. Simultaneously, EU export prices to Türkiye spiked by 50.9%, and import prices from Saudi Arabia rose by 82.3%. These simultaneous shocks reflected the global energy crisis and feedstock cost inflation that rippled through the petrochemical supply chain. The volatility analysis shows that Saudi Arabia and Indonesia had the highest coefficient of variation (CV) in import volumes, indicating highly unpredictable supply. For exports, Brazil and the Russian Federation were the most volatile partners. These price and supply shocks demonstrate the market's susceptibility to global events.

The Sectoral Impact: Diverging Fortunes Across Rubber Types

The segment breakdown reveals that the broad trends masked significant variation across different synthetic rubber products. Styrene-butadiene rubber (SBR, 400219) remained the largest traded segment by value for both imports and exports. However, the most dramatic decline was in Isoprene rubber (IR, 400260), where import volume collapsed from 137,079 tonnes in 2015 to just 15,792 tonnes in 2025 (-88.5%). This was likely linked to the loss of Russian supply, as IR is a key product in that country. Conversely, imports of Ethylene-propylene diene rubber (EPDM, 400270) and other specialized rubbers (400299) showed resilience or growth. On the export side, volumes of Halo-isobutene-isoprene rubber (CIIR/BIIR, 400239) fell sharply from 107,194 tonnes to 15,993 tonnes, indicating a loss of competitiveness in that niche. The detailed product segment data allows for this granular understanding of sectoral dynamics.

Increasing Import Reliance and Deeper Market Integration

The cumulative effect of these trends was a significant increase in the EU's vulnerability through trade. Net import reliance as a percentage of production plus imports rose by 44.2%, from 8.1% to 11.7%. More strikingly, trade intensity (the ratio of trade to production) surged by 45.5% to 60.8%, and export propensity (exports as a share of production) increased by 72.5% to nearly 40%. These metrics indicate that the EU synthetic rubber sector became more open and integrated into global markets, but this came at the cost of greater exposure to external price and supply fluctuations. The rising vulnerability indicators paint a picture of an industry that is increasingly reliant on international trade, with all the associated risks and opportunities.

Conclusion

Over the 2015-2025 decade, the EU's synthetic rubber market underwent a fundamental transformation. The bloc evolved from a position of near balance to one of pronounced trade deficit, driven by rising import prices and falling export volumes. This period was characterized by a strategic reorientation of import supplies away from Russia towards Asian and Middle Eastern partners, a contraction in domestic production volumes accompanied by a focus on higher-value output, and a dramatic increase in market volatility, culminating in the disruptive price shocks of 2022. The result is a European market that is more globally integrated but also more vulnerable to external supply and price dynamics. The future resilience of EU downstream industries, particularly in the automotive sector, will depend on managing these new dependencies and navigating the continued volatility in global synthetic rubber markets.
