Market evolution: Epoxides (CN 2910) — 2015–2025
Introduction
This report examines the European Union's external trade in epoxides and related three-membered ring compounds (Customs code 2910) over the period 2015–2025. The product group encompasses a range of industrially significant chemicals — from commodity bulk substances like propylene oxide and epichlorohydrin to high-value specialty derivatives — used across sectors such as coatings, adhesives, electronics, and pharmaceuticals. Over the decade, the EU's trade profile has undergone a profound structural transformation: imports have surged while exports have stagnated in volume, the trade deficit has ballooned, and the geographic concentration of suppliers has intensified sharply. The data reveal a market increasingly shaped by geopolitical realignment, regional production shifts, and rising dependency on a narrow set of external partners.
A Widening Trade Deficit Driven by Import Growth and Stagnant Exports
EU imports have nearly doubled in value while export volumes have declined
The most striking macro-level trend over 2015–2025 is the divergence between EU imports and exports. Import value surged from €230.6 million to €437.0 million (+89.5%), while import volumes rose from 168,864 tonnes to 284,607 tonnes (+68.5%). Over the same period, export value grew modestly from €136.4 million to €154.3 million (+13.1%), but export volumes contracted from 92,503 tonnes to 84,822 tonnes (−8.3%).
| Indicator | 2015 | 2025 | Change |
|---|---|---|---|
| Import value (€M) | 230.6 | 437.0 | +89.5% |
| Import volume (kt) | 168.9 | 284.6 | +68.5% |
| Export value (€M) | 136.4 | 154.3 | +13.1% |
| Export volume (kt) | 92.5 | 84.8 | −8.3% |
| Trade balance (€M) | −94.2 | −282.8 | −200.1% |
The EU's trade deficit in epoxides thus widened from −€94.2 million in 2015 to −€282.8 million in 2025, a deterioration of 200%. This reflects both the scale of import growth and the inability of EU exports to keep pace. Notably, unit values moved in diverging directions: import prices rose 12.5% over the period, while export prices climbed 23.3%, suggesting that the EU has been shifting toward higher-value, lower-volume export segments — a pattern consistent with a mature chemical industry ceding commodity volumes to lower-cost producers abroad.
Domestic production has declined in volume, reinforcing import dependency
EU production data confirms the structural shift. Production volumes fell from 2.86 billion kg in 2015 to 2.40 billion kg in 2025 (−16.2%), even as production value edged up from €2.11 billion to €2.21 billion (+4.9%). This pattern — declining tonnage but stable or rising value — indicates that EU producers are increasingly concentrating on higher-value specialty segments while withdrawing from bulk commodity production. The net import reliance metric, which stood at 2.4% in 2015 and reached 3.8% in 2025, confirms this growing dependence, though it dipped into negative territory in one year (reaching −7.9% at its trough), suggesting the EU was briefly a net exporter before the import surge took hold.
Geographic Realignment: The Rise of the United States and the Retreat of the United Kingdom
The United States has become the overwhelmingly dominant import supplier
The most dramatic geographic shift has been the explosive growth of US-origin imports. In 2015, the United States supplied €105.4 million of epoxides to the EU; by 2025, this had surged to €316.0 million (+199.8%). The US now accounts for an outsized share of the EU's import bill, reflecting the massive expansion of US petrochemical capacity in the Gulf Coast over the 2010s, which has given American producers a competitive cost advantage rooted in cheap shale gas feedstocks.
| Import partner | 2015 (€M) | 2025 (€M) | Change |
|---|---|---|---|
| United States | 105.4 | 316.0 | +199.8% |
| Korea, Republic of | 19.8 | 40.2 | +103.5% |
| China | 8.2 | 21.3 | +159.2% |
| United Kingdom | 36.0 | 2.6 | −92.9% |
| Japan | 14.4 | 13.9 | −3.2% |
| Brazil | 19.3 | 0.0 | −100.0% |
| Russian Federation | 5.5 | 3.1 | −43.0% |
Concentration on the import side has intensified accordingly. The Herfindahl-Hirschman Index (HHI) for import value more than doubled from 2,564 to 5,383 (+109.9%), crossing from a moderately concentrated market into highly concentrated territory. This is a significant structural risk factor: the EU's supply of epoxides is now far more dependent on a single source than it was a decade ago.
Brexit and geopolitical shocks have redrawn bilateral flows
The collapse of UK-sourced imports (−92.9%, from €36.0 million to €2.6 million) is one of the most striking bilateral shifts visible in the data. The United Kingdom was the EU's third-largest import source in 2015; by 2025, it had fallen to near-irrelevance. This dramatic decline almost certainly reflects the combined effects of Brexit — including customs frictions, regulatory divergence, and the re-routing of supply chains — and likely also shifts in UK domestic production patterns. A price shock event detected in UK imports in 2021 (abnormality score 427.7, with a +280% price shift) underscores the disruption that accompanied the Brexit transition.
Brazil, previously a significant supplier (€19.3 million in 2015), has been entirely eliminated from the EU's import portfolio by 2025, with imports dropping to a negligible €43. Russia, meanwhile, saw imports decline from €5.5 million to €3.1 million (−43.0%), a trend that likely accelerated after 2022 given the sanctions environment.
On the export side, the EU's top destinations have remained broadly stable — Switzerland, the United Kingdom, and the United States have consistently been the leading markets. However, export concentration has remained relatively flat (HHI: 1,977 → 1,914), suggesting a more diversified export base compared to imports. India has emerged as a notable growth market for EU exports, surging from €0.8 million to €7.1 million (+794%), possibly reflecting India's expanding downstream chemical and manufacturing sectors.
Product-Level Dynamics: Propylene Oxide Dominance and Ethylene Oxide's Collapse
Propylene oxide (291020) has become the dominant import product
At the six-digit level, the product composition of EU trade has shifted markedly. Propylene oxide (CN 291020) has consolidated its position as the single most important epoxide traded. EU imports of propylene oxide surged from 110,345 tonnes (€135.6 million) in 2015 to 208,623 tonnes (€278.2 million) in 2025 — a near-doubling in volume and value. Propylene oxide now accounts for roughly 64% of total import volume and the majority of import value within the CN 2910 heading.
Epichlorohydrin (CN 291030) has also grown significantly: imports rose from 20,311 tonnes to 51,416 tonnes (+153%), and the average import price increased from €1,306/t to €1,461/t. This growth likely reflects expanding demand from the epoxy resin and water-treatment sectors.
Ethylene oxide imports have virtually disappeared
In stark contrast, imports of ethylene oxide (CN 291010) have collapsed from 27,771 tonnes (€27.7 million) in 2015 to a mere 29 tonnes (€0.3 million) in 2025 — a decline of over 99.9%. This product is highly regulated due to its toxicity and carcinogenicity, and is typically produced and consumed close to the point of use given its hazardous nature and transport difficulties. The near-total disappearance of EU imports likely reflects a combination of increased EU domestic production capacity for ethylene oxide, stricter transport regulations, and possibly the relocation of downstream consumers.
The remaining category — other epoxides and derivatives (CN 291090), which includes specialty and higher-value products — has shown more moderate growth: import volumes rose from 10,438 tonnes to 24,493 tonnes (+135%), while values climbed from €40.7 million to €81.8 million (+101%). Average prices in this segment have remained elevated (€3,336/t in 2025), consistent with a portfolio of specialty chemicals. Notably, this is the segment where EU exports remain strongest, with volumes growing from 6,368 tonnes to 9,697 tonnes and values averaging around €44–50 million in recent years, reflecting the EU's comparative advantage in higher-value epoxide derivatives.
The EU's specialisation profile confirms a two-tier market
The specialisation analysis reveals a geographically concentrated production landscape. Belgium (RSCA: 0.54) and the Netherlands (RSCA: 0.36) are the most specialised EU producers in this product group, reflecting their roles as major petrochemical hubs with integrated refining and chemical complexes. Germany, despite being the largest single-country producer by share (31.2% of EU production), has a lower specialisation index (RSCA: 0.19), indicating that epoxides are a smaller part of its broader, more diversified chemical portfolio. France sits near the threshold of revealed comparative advantage (RSCA: −0.03), while several smaller EU members — Portugal, Lithuania, Sweden, Ireland, Finland — have essentially no export specialisation in this product group.
Conclusion
The EU's trade in epoxides (CN 2910) over 2015–2025 tells a story of structural transformation. The bloc has evolved from a relatively balanced market to one with a pronounced and growing trade deficit (−€282.8 million in 2025), driven by surging imports — particularly from the United States, which has leveraged its shale-gas cost advantage to become the overwhelmingly dominant supplier. At the same time, EU production volumes have declined, and the export base has shifted toward higher-value but lower-volume specialty products, consistent with the EU's broader pattern of industrial upgrading in chemicals.
Several risks stand out. The import HHI of 5,383 signals a highly concentrated supply base, with the EU increasingly reliant on a small number of partners. The near-total elimination of UK, Brazilian, and Russian suppliers — due to Brexit, supply chain realignment, and geopolitical sanctions respectively — has further narrowed the import base. Meanwhile, EU exports remain geographically diversified and have found new growth markets such as India, but export volumes are declining in absolute terms.
Looking forward, the twin pressures of energy cost competitiveness (a persistent structural disadvantage for EU producers relative to US and Middle Eastern competitors) and tightening environmental regulation will continue to shape this market. Policymakers concerned with supply security in the European chemical industry would do well to monitor the growing concentration of epoxide imports and the continued erosion of the EU's commodity production capacity.
