Market evolution: Ethylene glycol (CN 290531) — 2015–2025
Introduction
Ethylene glycol (ethanediol), classified under CN 290531, is a key organic chemical used primarily in the manufacture of polyester fibres, PET resins, and antifreeze formulations. Between 2015 and 2025, the EU's trade in ethylene glycol with non-EU countries underwent a profound transformation, marked by a collapse in both export and import volumes, a dramatic reconfiguration of trade partnerships, and a structural shift toward greater import dependency. This report examines the main dynamics shaping this market over the decade, drawing on trade data, partner-level breakdowns, and vulnerability indicators.
1. A Decade of Asymmetric Trade Contraction
The most striking feature of EU ethylene glycol trade between 2015 and 2025 is the sheer magnitude of decline in both trade flows, with exports contracting far more severely than imports. The EU went from being a meaningful ethylene glycol exporter to a predominantly inward-facing market.
Overall trade volumes collapsed across both directions
EU exports of ethylene glycol fell from 191,015 tonnes in 2015 to just 15,016 tonnes in 2025, a decline of 92.1%. In value terms, exports dropped from €156.4 million to €17.5 million (−88.8%). Imports, while also declining, fell by a more moderate 28.1% in volume (from 674,515 tonnes to 484,866 tonnes) and 53.5% in value (from €510.8 million to €237.3 million). Notably, imports had peaked at 870,404 tonnes and €577.7 million at some point during the period — well above their 2015 starting level — before falling back.
| Indicator | 2015 | 2025 | Period min | Period max | Change |
|---|---|---|---|---|---|
| Export value | €156.4 M | €17.5 M | €17.5 M | €195.9 M | −88.8% |
| Export volume | 191,015 t | 15,016 t | 15,016 t | 225,070 t | −92.1% |
| Export unit price | €819/t | €1,166/t | €580/t | €1,166/t | +42.4% |
| Import value | €510.8 M | €237.3 M | €237.3 M | €577.7 M | −53.5% |
| Import volume | 674,515 t | 484,866 t | 484,866 t | 870,404 t | −28.1% |
| Import unit price | €757/t | €489/t | €437/t | €772/t | −35.4% |
| Trade balance | −€354.4 M | −€219.8 M | −€499.8 M | −€219.8 M | +38.0% |
The export collapse was the dominant structural dynamic
The near-disappearance of EU ethylene glycol exports is the single most significant change in this market. While imports remained substantial throughout the period, exports effectively ceased to matter: the EU went from shipping 191,000+ tonnes to non-EU markets to just 15,000 tonnes. The export volume decline of 92.1% points to a fundamental loss of outward competitiveness in EU ethylene glycol production. The trade deficit did narrow in absolute terms (from €354 million to €220 million), but only because imports contracted by more in euro terms than the already-devastated exports.
Unit prices diverged sharply between imports and exports
A striking feature is the divergence in unit price trends. Export unit prices rose by 42.4%, from €819/t to €1,166/t, while import unit prices fell by 35.4%, from €757/t to €489/t. This suggests that the EU's remaining exports increasingly comprised higher-value or specialty-grade product, while global commodity ethylene glycol became significantly cheaper to import — likely reflecting expanded production capacity in the Middle East and Asia, where feedstock costs are structurally lower. The minimum import price of €437/t and the maximum export price of €1,166/t observed during the period highlight the growing premium of EU-origin product in the residual export basket.
2. A Dramatic Reconfiguration of Trade Partnerships
The period 2015–2025 saw a significant reshuffling of the EU's ethylene glycol trade partners. Traditional suppliers lost ground, geopolitical shocks eliminated certain sources, and the UK — once the EU's dominant export market — effectively disappeared from the picture.
Saudi Arabia's dominance in EU imports eroded substantially
Saudi Arabia remained the EU's largest single supplier throughout the period, but its share contracted dramatically — from €333.7 million in 2015 to €120.8 million in 2025 (−63.8%). Despite this decline, Saudi Arabia still represented roughly half of total EU import value by 2025, confirming the continued structural importance of Middle Eastern supply.
The United States became a more prominent supplier
The United States bucked the trend, with EU imports rising from €78.5 million to €109.8 million (+39.8%). The US likely gained competitiveness thanks to its shale gas revolution, which provides low-cost ethane feedstock for ethylene and subsequently ethylene glycol production. By 2025, the US had become the EU's second-largest supplier, narrowing the gap with Saudi Arabia.
Russian and Venezuelan supply channels effectively vanished
Imports from the Russian Federation collapsed from €17.6 million to under €1 million (−95.5%), while Venezuelan supply fell from €35.4 million to essentially zero (−100.0%). The Russian decline is closely linked to EU sanctions imposed following the 2022 invasion of Ukraine, while the Venezuelan collapse reflects the broader deterioration of that country's petrochemical sector over the decade.
The United Kingdom — once the EU's top export market — effectively disappeared
The most dramatic shift on the export side was the near-total collapse of trade with the United Kingdom. UK-bound exports fell from €129.1 million in 2015 to just €1.9 million in 2025 (−98.5%). As the UK absorbed over 82% of EU ethylene glycol exports by value in 2015, this collapse was the primary driver of the overall export decline. The timing and scale of this contraction are consistent with the trade disruptions associated with Brexit, which introduced new customs procedures, regulatory divergence, and logistical friction beginning in 2021. A price shock with an abnormality score of 20.4 and a 65.1% price shift was detected in UK exports in 2021, likely reflecting the sharp volume contraction and supply chain reconfiguration in the immediate post-Brexit period.

|---|---|---|---|---|
| Saudi Arabia | 333.7 | 120.8 | 426.0 | −63.8% |
| United States | 78.5 | 109.8 | 230.3 | +39.8% |

|---|---|---|---|---|
| United Kingdom | 129.1 | 1.9 | 165.0 | −98.5% |
| Türkiye | 2.7 | 0.3 | 17.0 | −90.4% |
| Norway | 8.7 | 0.8 | 8.7 | −91.2% |

| Switzerland | 2.9 | 1.8 | 4.4 | −37.2% |
| Serbia | 1.3 | 0.8 | 2.3 | −37.2% |
Import concentration remained high while export markets fragmented
The Herfindahl-Hirschman Index (HHI) for imports remained broadly stable, edging up slightly from 4,614 to 4,732 (+2.6%), confirming that import supply remained highly concentrated despite partner shifts. By contrast, the HHI for exports plummeted from 6,855 to 1,033 (−84.9%). This did not reflect a healthy diversification of export markets; rather, it was the mechanical consequence of the UK's collapse from an 82% share to near-zero, with no single replacement market emerging. The residual export base became more dispersed but also far smaller.
Belgian import and export volumes declined in tandem
The EU Member State breakdown reveals that Belgium was the largest EU importer (from €264.1 million to €89.9 million, −66.0%) and the largest exporter (from €108.9 million to €6.0 million, −94.5%) over the period. This dual role likely reflects Belgium's function as a logistics and petrochemical hub, centred on the Port of Antwerp. The Netherlands similarly saw its exports collapse from €29.3 million to under €1 million (−96.7%). Spain was a notable exception on the import side, with a relatively modest decline of just 2.8% (from €87.6 million to €85.2 million).
3. Shrinking Domestic Production and Growing Import Dependency
Underlying the trade dynamics was a significant contraction in EU domestic ethylene glycol production, which reinforced the bloc's structural dependence on imports even as overall market size diminished.
EU production declined by nearly 40%
According to PRODCOM data, EU production of ethylene glycol fell from approximately 1.47 billion kilograms (€868 million) in 2015 to 910 million kilograms (€520 million) in 2025, representing declines of 37.9% in volume and 40.1% in value. Production bottomed out at 780 million kilograms and €298 million during the period, indicating that some production lines were temporarily or permanently idled during the downturn.
Belgium emerged as the EU's sole specialised producer
The specialisation data for 2025 reveals a highly concentrated production landscape within the EU. Belgium recorded a Revealed Symmetric Comparative Advantage (RSCA) of 0.80 and an RCA of 8.94, making it by far the most specialised EU member in ethylene glycol. Belgium accounted for 75.7% of EU production volume, despite representing only 8.5% of total EU trade in the product. The Netherlands followed with an RCA of 1.06 (marginally above the threshold for comparative advantage), while all other major EU members exhibited RCA values well below 1, indicating no meaningful specialisation in this product.
| EU Member State | RCA | RSCA | Production share |
|---|---|---|---|
| Belgium | 8.94 | 0.80 | 75.7% |
| Netherlands | 1.06 | 0.03 | 15.4% |
| Lithuania | 0.97 | −0.02 | 0.6% |
| Poland | 0.46 | −0.37 | 3.1% |
| Bulgaria | 0.35 | −0.48 | 0.2% |
Net import reliance increased significantly
Despite the overall contraction in trade volumes, the EU's net import reliance rose from 22.2% in 2015 to 33.0% in 2025, peaking at 48.4% during the period. This increase reflects the fact that while both production and exports declined, exports fell far more steeply (−92.1% in volume) than production (−37.9%), narrowing the output-to-consumption gap. In other words, the EU's domestic market shrank, but its ability to serve that market from domestic sources shrank even faster.
Export propensity collapsed, signalling a structural loss of outward orientation
The export propensity — the share of production exported to non-EU markets — fell from 11.8% to 6.2% (−47.8%), reaching its period minimum in 2025. This metric registered the highest salience score (91.6) among the vulnerability indicators, confirming that the loss of export orientation was the single most important structural vulnerability of the EU ethylene glycol market over this decade. The trade intensity, by contrast, remained relatively stable at around 37–40%, indicating that the market's overall degree of international integration did not change dramatically — but its composition shifted decisively toward imports.
Volatility varied widely across partners
The volatility analysis reveals widely differing levels of trade stability across partners. Among import suppliers, Singapore and South Korea showed the highest coefficients of variation (2.34 and 1.97 respectively), reflecting sporadic and opportunistic trade patterns rather than stable supply relationships. On the export side, India (CV: 2.49) and China (CV: 2.23) showed the highest volatility. By contrast, Saudi Arabia displayed relatively low import volatility (CV: 0.28), confirming its role as a stable anchor supplier even as volumes declined.
Conclusion
The EU ethylene glycol market between 2015 and 2025 underwent a profound structural transformation. Trade volumes contracted across both imports and exports, but the collapse of exports — driven primarily by the loss of the UK market following Brexit — was the defining dynamic. Domestic production declined by nearly 40%, concentrating heavily in Belgium, while the EU's net import reliance rose to one-third of apparent consumption. The supplier landscape shifted notably: Saudi Arabia lost ground, the US gained share thanks to feedstock advantages, and Russian and Venezuelan supplies effectively disappeared under the combined pressure of sanctions and economic collapse. The result is an EU market that is smaller, more import-dependent, and more concentrated in its remaining production base than it was a decade ago — a structural evolution that raises questions about the bloc's long-term resilience in this critical chemical segment.
