Market evolution: Ethylene (CN 290121) — 2015–2025

Introduction

Ethylene is the world's most produced organic chemical and a foundational building block for the petrochemical industry, feeding into polyethylene, ethylene oxide, styrene, and a wide range of derivatives. For the European Union, tracking its trade in ethylene (customs code 290121) over the 2015–2025 period reveals a market undergoing a profound structural transformation. EU production declined by roughly one-third, exports collapsed to near-negligible levels, and the bloc's reliance on external suppliers — particularly the United States and Norway — surged. This report examines the data to identify and explain the principal dynamics shaping the EU ethylene market over the past decade.

All figures, unless otherwise noted, refer to the General Overview of EU trade with non-EU countries for CN 290121.

1. A Structural Shift: From Marginal Exporter to Major Importer

The most striking feature of the EU ethylene market over 2015–2025 is the simultaneous collapse of exports and growth of imports, converting the EU from a modest participant in global ethylene trade into a structurally import-dependent region.

1.1 Exports in freefall

EU exports of ethylene fell dramatically over the period:

In absolute terms, the EU went from exporting nearly 179,000 tonnes of ethylene to just over 30,000 tonnes — a decline of over 83%. The peak year for export value was likely around 2018–2019, when the maximum reached €533 million, suggesting a brief export surge mid-period that subsequently reversed entirely. The modest rise in export unit prices (+8.0%) is insufficient to compensate for the volume collapse; the EU simply lost its position as a competitive ethylene exporter.

1.2 Imports expand, driven by rising volumes and prices

In contrast, EU imports grew substantially:

Import volumes grew by over 21%, while import values rose by nearly 50% — the difference attributable to a 23.4% increase in average import prices. This combination of volume growth and price inflation signals both structural demand for imported ethylene and exposure to global price cycles.

1.3 A widening trade deficit

The EU's trade balance in ethylene worsened from −€762 million in 2015 to −€1,314 million in 2025, a deterioration of 72.4%. The deficit was at its widest around 2021–2022 (minimum: −€1,554 million), coinciding with the post-COVID demand recovery and the energy price spike linked to the Russia-Ukraine conflict.

2. A Reconfigured Supplier Landscape: The Rise of the United States and the Decline of the United Kingdom

Behind the headline figures lies a dramatic reconfiguration of the EU's ethylene supply geography. The top partners data reveals that traditional European suppliers have lost ground while transatlantic and Nordic sources have surged.

2.1 The United States: From minor supplier to dominant force

The most dramatic shift in EU ethylene imports is the rise of the United States:

US ethylene exports to the EU grew from €60 million to over €566 million — an increase of nearly 845%. This reflects the shale gas revolution in the United States, which dramatically lowered feedstock costs for US crackers and made US ethylene highly competitive on global markets. By 2025, the United States had overtaken the United Kingdom as the EU's single largest external ethylene supplier.

2.2 The United Kingdom: Brexit and structural decline

The United Kingdom, historically the EU's dominant ethylene supplier (accounting for over €628 million in 2015, or roughly 70% of EU imports by value), saw its share decline to €366 million by 2025 — a 41.7% drop. This decline likely reflects a combination of factors: the UK's own petrochemical industry restructuring, the post-Brexit trade frictions, and increased competition from cheaper US and Norwegian supply. Notably, UK imports also exhibited significant volatility (coefficient of variation of 0.49), and a price shock event was detected in 2021, with an abnormality score of 2.5 and a 63.2% price shift.

2.3 Norway: Steady Nordic growth

Norway more than doubled its ethylene exports to the EU, from €123 million to €328 million (+167.6%), positioning itself as the third-largest supplier. Norway's relatively low volatility (CV of 0.21) and consistent growth suggest a stable, long-term supply relationship — likely facilitated by geographic proximity, pipeline logistics, and Norway's integration into the European Economic Area.

2.4 Other suppliers: Decline and instability

Several other suppliers saw declines or high volatility:

• Libya fell from €105 million to €34 million (−67.4%), reflecting ongoing political instability.
• Saudi Arabia and Brazil remained minor and volatile suppliers (CVs of 0.81 and 1.12, respectively).
• Russia, while not in the top seven, exhibited extremely high volatility (CV of 1.87), consistent with the disruptions following the 2022 invasion of Ukraine.

2.5 Export destinations: Collapse across the board

On the export side, the EU lost virtually all of its major ethylene markets:

The near-total disappearance of EU ethylene exports to the UK (−96.6%) mirrors the UK's own declining import needs and post-Brexit trade barriers. Indonesia, once the largest non-European destination, also saw a 73.5% decline. The only notable growth story was Algeria, which went from negligible levels (€22,485) to €8 million — though from a very low base.

2.6 The US price shock and EU import volatility

The volatility analysis shows that US ethylene supply to the EU is highly volatile (CV of 0.99), second only to Brazil (1.12) and Russia (1.87) among import partners. The 2017 price shock in exports to Indonesia — with an abnormality score of 5.2 and a 32.4% price shift accounting for 40.9% of export value — suggests a major market disruption that year, possibly linked to regional supply-demand imbalances in Southeast Asia.

3. A Declining Domestic Industry: Production, Specialisation, and Growing Import Dependence

The trade data must be read alongside the EU's domestic ethylene production trajectory, which reveals an industry in contraction — with direct consequences for import reliance and the EU's strategic position in the petrochemical value chain.

3.1 Production in decline

EU ethylene production volumes fell sharply:

The EU produced roughly 12.1 million tonnes of ethylene in 2015; by 2025, output had fallen to 8.1 million tonnes — a decline of over one-third. Production value declined less steeply (−18.8%), reflecting higher average prices. The production peak was around 14.2 million tonnes (likely 2017–2018), after which a sustained decline set in — driven by high European energy costs, ageing cracking capacity, and intensifying competition from US and Middle Eastern producers.

3.2 Rising import dependence

The EU's net import reliance rose from 13.5% in 2015 to 17.1% in 2025 (+26.4%), reaching its highest point in the dataset. The minimum was just 5.8% (likely in 2018, when production peaked and exports were still significant). The convergence of declining production, collapsing exports, and rising imports has pushed the EU toward its maximum historical dependence on external ethylene supply.

Export propensity — the share of domestic production exported — collapsed from 0.72% to just 0.13% (−82.1%), confirming that the EU has effectively exited the global ethylene export market.

3.3 Geographic concentration of production within the EU

The specialisation data for 2025 reveals a highly uneven distribution of ethylene production across EU member states:

The Netherlands alone accounts for nearly half of EU ethylene production (48.5%), followed by Belgium (17.2%) and Germany (16.0%). Finland, despite a small absolute share (6.8%), shows the highest specialisation (RSCA of 0.74), indicating that ethylene is a far more prominent export in Finland's trade profile than for other members. Germany, despite being the EU's largest economy, has a revealed comparative disadvantage in ethylene (RCA below 1), consistent with its broader chemical industry shifting toward higher-value derivatives.

Several member states — including Romania, Latvia, Denmark, and Greece — have essentially no ethylene production (RCA of zero), making them entirely dependent on intra-EU or external supply.

3.4 Import concentration: Diversification in progress

The Herfindahl-Hirschman Index for imports fell from 5,174 to 3,149 (−39.1%), indicating that the EU's import sources have become significantly less concentrated. In 2015, the UK alone dominated; by 2025, supply was more evenly distributed among the US, Norway, the UK, and others. This diversification reduces single-supplier risk but also reflects the EU's growing inability to self-supply.

In contrast, export concentration rose sharply (HHI from 2,361 to 4,368, +85.0%), reflecting the shrinking base of EU exports and their concentration in fewer, smaller destinations.

3.5 Shifting roles of EU member states in trade

The reporters data reveals how intra-EU trade flows have reconfigured:

Belgium consolidated its position as the EU's primary entry point for ethylene imports (from €373 million to €704 million), consistent with its role as a petrochemical hub (Antwerp-Rotterdam-Amsterdam cluster). Italy and France dramatically increased their import activity — Italy's imports grew by over 1,600%, suggesting either new cracking capacity coming online reliant on imported feedstock, or a shift from domestic to imported ethylene. Meanwhile, Germany's imports fell by 79.2%, likely reflecting its own production decline and reduced downstream demand. On the export side, Italy and Portugal effectively ceased ethylene exports entirely.

Conclusion

The EU ethylene market underwent a fundamental transformation between 2015 and 2025. The bloc's domestic production declined by a third, exports collapsed to negligible levels, and import dependence rose to its highest recorded level. The United States emerged as the EU's most dynamic supplier, capitalising on shale-gas-driven cost advantages, while the United Kingdom — historically the dominant partner — saw its role diminish significantly. Norway consolidated a stable position as the third-largest supplier.

These trends carry significant strategic implications. The EU's growing reliance on a small number of extra-EU suppliers, combined with the high volatility of some supply routes (notably the US, with a coefficient of variation near 1.0), creates exposure to supply disruptions and price shocks. The concentration of domestic production in a handful of member states (the Netherlands alone accounts for nearly half) further amplifies regional vulnerabilities. As global petrochemical investment continues to flow toward the US Gulf Coast, the Middle East, and Asia, the EU faces a structural challenge in maintaining a competitive ethylene production base — with downstream consequences for the entire European chemicals value chain.
