Market evolution: Compounded rubber (CN 4005) — 2015–2025

Introduction

This report examines the EU's external trade in compounded, unvulcanised rubber (Customs heading CN 4005) over the period 2015–2025. CN 4005 covers rubber compounded with carbon black or silica (subheading 400510), other compounded rubber in primary forms (400599), in plates, sheets or strip (400591), and in solutions or dispersions (400520). The product is an intermediate material used extensively in the tyre and automotive-parts industries, making its trade flows a useful barometer for the health of European manufacturing.

Over the decade under review, the EU's trade position in this product category underwent a striking transformation. Total export value rose by 11.2% while import value fell by 21.3%, and the trade surplus nearly doubled from €196 million to €359 million. Beneath these headline figures, however, lie significant structural shifts: a pronounced volume-to-price substitution, a dramatic reorientation of geographic trade flows following Brexit and the Russia–Ukraine conflict, and growing concentration of production in a handful of specialised EU Member States.

1. Rising prices mask a decline in physical trade volumes

The most striking feature of the decade is the divergence between value and volume trends in both exports and imports. Monetary growth conceals a contraction in the actual tonnes of compounded rubber crossing the EU's external borders.

1.1 Import volumes nearly halved while import prices surged

EU imports of CN 4005 fell from 154,628 tonnes in 2015 to just 87,369 tonnes in 2025—a decline of 43.5%. Over the same period, the average import price climbed from €2,820 per tonne to €3,930 per tonne (+39.4%). Because of this price inflation, the fall in import value was more moderate at –21.3% (from €436 million to €343 million), but the underlying physical shrinkage is unmistakable. The import volume decline was concentrated in the first half of the period, with most of the loss occurring between 2018 and 2021.

1.2 Export volumes also contracted, but prices rose even faster

EU exports tell a parallel story: volumes declined from 262,245 tonnes to 227,227 tonnes (–13.4%), yet export value increased by 11.2% to reach €703 million in 2025. The average export price rose from €2,410 per tonne to €3,092 per tonne (+28.3%). Notably, the export price increase was less pronounced than the import price increase, which contributed to an improvement in the EU's terms of trade for this product.

1.3 Domestic production expanded, reinforcing the EU's net-exporter status

EU domestic production data, reported in kilograms, shows a 14.6% increase in volume (from 1.34 billion kg in 2015 to 1.54 billion kg in 2025) and a remarkable 93.7% increase in value (from €2.27 billion to €4.39 billion). This confirms that price inflation—likely reflecting higher raw-material costs and energy prices—was not limited to cross-border trade but was also embedded in domestic production. The combination of growing production, falling imports, and steady export values pushed the EU's net import reliance from a mildly positive +0.85% in 2015 to a firmly negative –9.55% in 2025, confirming that the EU became a consistent net exporter of compounded rubber over this decade.

2. Brexit and geopolitics redraw the EU's trade map

The geographic composition of EU trade in CN 4005 was reshaped by two major events: the United Kingdom's departure from the EU single market and customs union (completed at end-2020) and the imposition of EU sanctions on Russia following the 2022 invasion of Ukraine. Both events left deep marks on the data.

2.1 The UK was the dominant partner and its share collapsed

In 2015, the United Kingdom was by far the EU's largest trade partner for this product, accounting for €227 million in imports (52% of total extra-EU imports) and €148 million in exports (23% of total extra-EU exports). By 2025, those figures had fallen to €130 million in imports (–42.6%) and €58 million in exports (–61.2%). The UK's share of EU imports dropped from over half to roughly 38%, and its share of EU exports fell from 23% to 8%.

The decline was not linear but stepped: both import and export flows with the UK fell sharply around 2020–2021, coinciding with the end of the Brexit transition period. This is consistent with the re-introduction of customs formalities, rules-of-origin requirements, and border frictions that reduced the efficiency of integrated UK–EU supply chains in the rubber sector.

2.2 Russian exports collapsed to near zero under sanctions

EU exports to the Russian Federation fell from €43.6 million in 2015 to essentially zero (€502) in 2024–2025, representing a –100% decline. This was identified as a supply shock with an abnormality score of 3.6 and a value share of 6.0% at the time of the shock's centre (2024). The collapse reflects the progressive tightening of EU sanctions and export restrictions. While Russia was never the EU's single largest destination, its complete exit from EU export flows meant that rubber manufacturers needed to find alternative markets.

2.3 New and growing partners partially absorbed displaced flows

Several partner countries saw significant increases in EU trade over the period, helping to compensate for the loss of UK and Russian flows:

• Serbia emerged as a major EU export destination, with exports surging from €27 million to €122 million (+354.7%), making it the third-largest export partner by 2025. Serbia's proximity and its EU candidate-country status, with preferential trade arrangements, likely facilitated this reorientation.
• Thailand grew as an import source (from €38 million to €58 million, +54.1%), reflecting its role as a major global rubber producer.
• China more than doubled as an import source (from €7 million to €19 million, +175.7%), while remaining a stable EU export market (~€77 million).
• Mexico became a fast-growing export market (from €27 million to €64 million, +138.7%), likely linked to EU–Mexico automotive supply chains.
• Turkey grew on both sides: as an import source (+14.5% to €46 million) and as an export destination (+59.4% to €89 million), underscoring its role as a key manufacturing bridge between Europe and emerging markets.

2.4 Import concentration fell sharply as sourcing diversified

The Herfindahl-Hirschman Index (HHI) for import value fell from 3,197 to 2,169 (–32.2%), moving the import market from a moderately concentrated structure towards a more competitive one. The decline was driven by the UK losing its dominant share and smaller suppliers—Thailand, China, Turkey—gaining ground. Export concentration also fell, albeit more modestly (from 1,010 to 871, –13.8%), reflecting the redistribution of EU exports away from the UK and Russia towards Serbia, Mexico, Turkey, and other markets.

3. Price shocks, segmental shifts, and intra-EU specialisation reshape the market

Beyond the headline trade figures, the data reveals important dynamics at the product-subheading level, in terms of price volatility, and in the intra-EU distribution of production and trade.

3.1 Import prices spiked in 2022, particularly from Turkey

A notable price shock was detected in 2022 for EU imports from Turkey, with an abnormality score of 47.8, a price shift of +22.8%, and a value share of 13.4%. This coincided with the global energy and raw-material price surge of 2022 and with the sharp depreciation of the Turkish lira, which may have affected pricing dynamics in complex ways (competitiveness gains for Turkish exporters offset by input-cost inflation). The overall import price increase across all partners was most pronounced in the subheading 400520 (solutions and dispersions), where prices more than doubled over the decade, rising from €5,154/t to €10,119/t (+96.3%).

3.2 Subheading 400510 (carbon black/silica compounds) dominates but import volumes contracted

The largest subheading by both value and volume is 400510—rubber compounded with carbon black or silica. In 2025, it accounted for 57% of total import value (€196 million) and 54% of total export value (€384 million).

However, import volumes in this subheading fell from 84,526 tonnes to 51,176 tonnes (–39.5%), while import prices rose from €2,505/t to €3,838/t (+53.2%). This suggests that the EU's domestic carbon-black rubber compounding capacity has expanded, reducing the need for external sourcing while global feedstock prices pushed up unit values.

Export volumes in 400510 also declined (from 124,575t to 111,875t, –10.2%) but export value actually grew (from €298 million to €384 million, +28.7%), driven by the price increase from €2,394/t to €3,430/t (+43.3%).

3.3 Subheading 400599 (other primary forms) saw the steepest volume declines

Imports of 400599 (compounded rubber in primary forms, excluding solutions, carbon-black compounds, and plates/sheets) fell from 54,142 tonnes to 24,840 tonnes (–54.1%), the steepest volume decline of any subheading. Export volumes were more resilient (from 66,762t to 73,750t, +10.5%), though they peaked in 2022 at 96,975 tonnes before retreating. This subheading's import decline may reflect both EU production growth and a shift towards sourcing carbon-black-compounded rubber (400510) domestically.

3.4 Production specialisation concentrated in Germany, Italy, and France

The specialisation analysis for 2025 reveals that EU production of CN 4005 is heavily concentrated in a few Member States:

Germany alone accounts for 30% of EU production, followed by Italy (15%) and France (12%). Germany is also the EU's largest exporter (€222 million in 2025, +17.3% vs. 2015), followed by Italy (€135 million, +4.3%). Romania stands out with the highest revealed comparative advantage (RCA of 3.06), suggesting a small but highly specialised production base—possibly linked to tyre manufacturing investments by global firms.

Belgium, once a major exporter (€76 million in 2015), saw its export value collapse to just €10 million (–86.5%), a dramatic decline that may reflect the relocation of compounding activities or changes in intra-EU routing of goods.

3.5 Trade intensity rose even as volumes fell, signalling increasing openness

The EU's trade intensity—the combined share of imports and exports relative to domestic production—increased from 17.9% to 22.2% (+24%). Meanwhile, export propensity (exports as a share of production) grew even more strongly, from 9.5% to 16.3% (+72.5%). This means that even as physical trade volumes contracted, the EU economy became more, not less, integrated with global markets for this product. The rise in export propensity, in particular, indicates that European compounded rubber producers are increasingly oriented towards external markets.

Conclusion

The EU's trade in compounded rubber (CN 4005) over 2015–2025 is a story of structural transformation driven by the interplay of price inflation, geopolitical disruption, and evolving industrial geography. The headline figures—a larger trade surplus, stable export values, and declining imports—suggest a market in rude health. But beneath the surface, physical trade volumes contracted significantly on both the import and export sides, with rising prices doing the heavy lifting in preserving monetary values.

The most consequential shifts were geographic. Brexit dramatically reduced the UK's role as the EU's primary trade partner for this product, while sanctions severed the Russian export market entirely. These losses were partly absorbed by growing trade with Serbia, Mexico, Thailand, China, and Turkey, leading to a more diversified—and therefore less concentrated—trade structure. Import concentration (HHI) fell by 32%, improving the EU's supply resilience.

At the product level, carbon-black and silica-compounded rubber (400510) remained the dominant subheading, but its import volumes declined sharply, suggesting growing EU self-sufficiency in this category. The price increases across all subheadings—particularly the near-doubling of prices for solutions and dispersions (400520)—reflect the broader inflationary environment and the rising cost of energy and raw materials in rubber compounding.

Looking forward, the EU appears well-positioned as a net exporter of compounded rubber, with rising export propensity and a diversified partner base. However, the concentration of production in a handful of Member States (Germany, Italy, France accounting for 57% of output) and the persistently high volatility of certain trade corridors (notably with Japan and the United States) suggest that supply-chain risks have not been fully eliminated.
