Market evolution: Acyclic ethers (CN 29091990) — 2015–2025

Introduction

This report examines the EU's external trade in acyclic ethers and their halogenated, sulphonated, nitrated or nitrosated derivatives (excluding diethyl ether and ETBE) over the period 2015–2025. The product, classified under customs code 29091990, is a residual category within the broader group of acyclic ethers (HS 290919). It covers a range of industrial chemical intermediates used in solvents, fuels, pharmaceuticals, and polymer production.

Over the decade under review, the EU's trade position in this product category underwent a profound transformation. The Union moved from a comfortable trade surplus to a significant deficit, driven primarily by an unprecedented surge in imports — particularly from China. Meanwhile, export values stagnated, trade partnerships reconfigured, and concentration in both import and export flows intensified markedly. The following sections detail and interpret these dynamics.

1. From Surplus to Deficit: The Collapse of the EU Trade Balance

The most striking feature of the 2015–2025 period is the complete reversal of the EU's trade balance in acyclic ethers. What began as a healthy surplus evolved into a substantial structural deficit, reflecting a dramatic asymmetry between the trajectories of imports and exports.

1.1 Imports surged while exports flatlined

Between 2015 and 2025, EU imports of CN 29091990 grew enormously, while exports barely moved:

Import volumes nearly quadrupled (+293.3%), while import values "only" rose by 153.5% because unit prices fell significantly (−35.6%). This price decline likely reflects the influx of lower-cost supplies, particularly from Asia. Export volumes and values, by contrast, remained broadly stable.

1.2 The trade balance swung into deep deficit

The EU's trade balance in this product deteriorated by €416 million over the decade:

The net import reliance indicator confirms this shift: it stood at 41.4% in 2015, fell to a minimum of −24.8% (indicating the EU was temporarily a net exporter), and then rebounded to 12.0% by 2025. While the 2025 figure appears moderate, it masks the underlying scale: the absolute deficit of over €300 million is substantial for a single chemical product line.

1.3 EU production declined in volume but increased in value

Available EU production data adds context. Domestic output (matched to Prodcom code 20.14.63.10) declined in quantity by 17.2% (from 2,174 thousand tonnes to 1,800 thousand tonnes), yet its estimated value rose by 49.7% (from €1.40 billion to €2.10 billion). This suggests that EU producers have shifted toward higher-value, more specialised variants of acyclic ethers, while lower-margin, commodity-grade products increasingly come from abroad.

2. The China Shock: A Tectonic Reconfiguration of Trade Partnerships

Behind the headline import surge lies a dramatic geographic reorientation. China emerged as the dominant source of EU imports by a wide margin, displacing traditional suppliers and fundamentally reshaping the market's competitive landscape.

2.1 China's import share exploded from near-negligible to dominant

The growth in Chinese imports into the EU over the decade was extraordinary:

China's imports grew from under €5 million to over €365 million — an almost 77-fold increase. By 2025, China alone accounted for roughly half of all EU imports by value, a level of concentration that was unimaginable a decade earlier.

2.2 Export destinations also shifted substantially

On the export side, the picture was more mixed:

Türkiye became by far the EU's largest export market, growing from €78 million to €256 million (+227%). In contrast, exports to several traditional partners collapsed — most notably Mexico (−98.5%), the United States (−69.5%), and the United Kingdom (−68.7%). The UK decline is consistent with the trade disruptions following Brexit, while the drops in US and Mexican flows may reflect competitive pressures from lower-cost Asian supply redirecting demand patterns.

2.3 Intra-EU trade patterns reflect shifting industrial geography

Among EU member states, the Netherlands remained the dominant hub for both imports and exports, consistent with its role as a major chemical logistics centre (Rotterdam). However, notable shifts occurred:

• Cyprus emerged as a significant import destination (from €39,012 to €157,231,111), likely reflecting the establishment of trading intermediaries.
• Belgium and Spain saw large import increases (+773.5% and +3,459.0% respectively), suggesting growing domestic consumption or re-export activity.
• On the export side, Belgium grew strongly (+1,035.8%), while Lithuania virtually disappeared (−99.9%).

These shifts within the EU suggest that the growing import volumes are not merely transiting through traditional gateways but are increasingly absorbed by a broader set of member states.

3. Rising Concentration and Price Shocks: Growing Fragility in Trade Flows

The period 2015–2025 was characterised by rising concentration in both import and export markets, alongside episodes of significant price volatility. These trends point to increasing fragility in the EU's external trade relationships for this product category.

3.1 Market concentration intensified on both sides

The Herfindahl-Hirschman Index (HHI) for both imports and exports rose substantially:

An HHI above 2,500 is generally considered indicative of a highly concentrated market. By 2025, both import and export sides exceeded this threshold. The import concentration is driven primarily by China's dominance, while the export concentration reflects the growing weight of Türkiye as a single destination. This dual concentration creates vulnerability: any disruption in the China–EU or EU–Türkiye trade corridor could have outsized effects on the overall market.

3.2 Several trade flows exhibited extreme volatility

The coefficient of variation (CV) across partner countries reveals considerable instability in certain flows:

High CV values (>1.0) indicate flows that swing dramatically from year to year. China's import CV of 1.90 is particularly noteworthy given its sheer volume — this combination of large scale and high volatility makes the EU's import profile especially sensitive to Chinese supply dynamics.

3.3 Notable price shocks marked the period

The supply shock analysis identified several significant events:

The UK import price shock in 2018 (an abnormality score of 229.1, representing a doubling of unit prices) may reflect pre-Brexit stockpiling or supply chain reconfiguration. The Mexico export price shock in 2020 (a nearly five-fold price increase, with an abnormality of 22.6) coincides with the COVID-19 pandemic's disruption of global chemical supply chains. The 2022 Swiss export price spike aligns with the broader energy-price shock following Russia's invasion of Ukraine, which particularly affected European chemical production costs.

3.4 Export propensity rose sharply even as trade intensity moderated

The trade intensity of EU production in this product declined slightly from 50.7% to 46.2% (−8.9%), meaning that a somewhat smaller share of total output (domestic production + net imports) was traded externally. However, the export propensity — the share of domestic production exported — surged from 10.7% to 25.2% (+137.0%). This divergence suggests that EU producers increasingly targeted foreign markets with their output, even as the overall trade openness of the product category moderated due to the import surge. The salience analysis confirms that export propensity was the most dynamic metric of the period.

Conclusion

The EU's market for acyclic ethers (CN 29091990) underwent a fundamental transformation between 2015 and 2025. The most consequential change was the shift from a trade surplus of €113 million to a deficit of €303 million, driven by an explosive growth in imports — particularly from China, whose shipments to the EU rose by over 7,600% in value terms. At the same time, export values remained essentially flat, with growth concentrated heavily in the Türkiye corridor.

Several structural features of this market now warrant attention. The EU's domestic production has pivoted toward higher-value segments, but this has come at the cost of growing import dependence for volume. Market concentration has reached high levels on both the import and export sides, creating potential vulnerabilities. The combination of China's dominant and volatile import presence, along with the EU's increasing reliance on Türkiye as an export outlet, means that geopolitical or logistical disruptions in either corridor could have significant consequences for EU producers and downstream users of these chemicals.

Looking ahead, the key question is whether the EU can diversify its import sources and export destinations to reduce concentration risk, or whether the competitive pressures that drove the China surge will deepen further. The data suggests that without deliberate market diversification, the EU's exposure to single-partner concentration in this product category will remain elevated.
