Market evolution: Acyclic ethers (CN 290919) — 2015–2025

Introduction

CN 290919 covers acyclic ethers and their halogenated, sulphonated, nitrated or nitrosated derivatives, excluding diethyl ether. It is a residual heading within the broader ethers family (HS 2909), bundling together two sub-products: tert-butyl ethyl ether (ETBE, CN 29091910) — a biofuel blending component — and all other acyclic ethers (CN 29091990), which encompass a wide range of industrial solvents, intermediates and specialty chemicals.

Over the period 2015–2025, EU trade in this product category underwent a dramatic transformation. Total import values more than doubled, rising from €436 million to €927 million, while export values barely budged from €402 million to €421 million. The EU consequently swung from a small trade deficit of €34 million in 2015 — and a peak surplus of €262 million in 2017 — to a record deficit of €505 million by 2025. Behind these headline figures lay a fundamental reorientation of trade partners, sharp price adjustments, and diverging trajectories between the ETBE and non-ETBE sub-segments.

This report examines the main dynamics underpinning this evolution, structured around three core themes: the widening trade gap, the geographic reshaping of trade flows, and the role of price trends and sub-product divergence.

1. A Tripled Import Bill and the Collapse of the EU Trade Surplus

1.1 Import volumes nearly tripled while export volumes stagnated

The most striking feature of the 2015–2025 period is the asymmetric growth between imports and exports. EU import volumes rose from 433,000 tonnes to 1,182,000 tonnes — an increase of 173.2% — while export volumes grew only 6.4%, from 437,000 to 465,000 tonnes. In value terms, the gap was similarly pronounced: imports surged 112.7% (from €436 million to €927 million) against a modest 4.7% rise in exports (from €402 million to €421 million). The following table summarises the overall trade evolution:

The divergence in unit prices is notable: import prices fell by 22.2% while export prices declined only 1.5%. This indicates that the surge in import volumes was not simply a price effect but reflected a genuine increase in the quantity of product entering the EU — often at lower unit costs — consistent with the entry of new, cost-competitive suppliers.

1.2 The EU swung from a €262 million surplus to a €505 million deficit

The trade balance followed a striking arc over the decade. In 2015, the EU recorded a modest deficit of €34 million. By 2017, a combination of strong export performance (€541 million, driven in part by an ETBE export boom) and moderate imports had produced a peak surplus of €262 million. From 2018 onward, however, imports began climbing faster than exports, and by 2022 the balance had turned decisively negative (−€261 million). The deficit widened further to €505 million by 2025.

The 2020 dip — when both imports and exports fell sharply, likely reflecting the COVID-19 demand shock — proved temporary. The subsequent recovery was highly asymmetric: by 2022, imports had reached a record €942 million, while exports peaked at €681 million before declining in subsequent years. The net import reliance indicator tells a nuanced story: it stood at 41.4% in 2015, fell to a minimum of −24.8% during the 2017 surplus period, and settled at 12.0% in 2025.

1.3 Domestic production shifted toward higher-value output

While EU production volumes declined by 17.2% (from approximately 2,174,000 tonnes to 1,800,000 tonnes), production values rose by 49.7% (from €1,403 million to €2,100 million). This implies a near-doubling of average unit production values over the decade, suggesting that the EU chemical industry shifted its product mix toward higher-value, more specialised derivatives. The decline in physical output — combined with the surge in import volumes — indicates that the EU increasingly relied on external suppliers for standard-grade acyclic ethers while concentrating domestic production on premium segments.

The export propensity (exports as a share of output) doubled from 10.7% to 25.2%, confirming that the EU became more export-oriented in relative terms — even as its absolute export volumes barely grew. Meanwhile, trade intensity (total trade as a share of domestic supply) edged down from 50.7% to 46.2%, reflecting the growing weight of domestic consumption absorbed by imports.

2. Geographic Reorientation: China and Turkey Dominate New Trade Patterns

2.1 China's share of EU imports surged from 1% to 41%

The most dramatic geographic shift in EU trade for CN 290919 was the emergence of China as the dominant import supplier. In 2015, China accounted for just €4.7 million of EU imports (1.1% of the total); by 2025, this had grown to €375.8 million — a staggering 7,916% increase — representing 40.6% of all imports. The top import partners data illustrates the scale of this transformation:

Brazil, which was the EU's largest import partner in 2015 (37.1% share), remained broadly stable in absolute terms but was displaced to second position. The United States and Saudi Arabia also grew as suppliers. The United Kingdom, by contrast, saw its exports to the EU decline by 53.2% — a pattern likely linked to post-Brexit trade frictions and supply chain reconfiguration. On the import concentration front, the HHI for imports by value remained relatively stable (2,564 to 2,628), but this stability masks the underlying rotation from Brazil to China as the primary source.

Among EU member states, the Netherlands remained the largest import gateway (€444 million in 2025, up 62.8% from 2015), while Cyprus emerged as a surprisingly significant hub (from €39,000 to €157 million), and France and Belgium both recorded sevenfold increases in their import values.

2.2 Turkey consolidated its position as the EU's primary export destination

On the export side, Turkey emerged as the overwhelmingly dominant partner for EU acyclic ethers. In 2015, Turkey absorbed €78 million of EU exports (19.5% of the total); by 2025, this had grown to €256 million — a 227% increase — accounting for 60.9% of all extra-EU exports. The top export partners data reveals this dominance:

Several formerly important export destinations contracted sharply. Mexico, which imported €50 million of EU acyclic ethers in 2015, saw purchases collapse to under €1 million by 2025 (−98.5%). The United States and United Kingdom also recorded steep declines of 61.5% and 69.4% respectively. These losses were more than offset by Turkey's growth, creating an increasingly lopsided export structure.

2.3 Export concentration intensified sharply while import sources remained more diversified

The Herfindahl-Hirschman Index (HHI) for export concentration by value rose from 1,364 to 4,003 — a 193% increase that moves the market from "moderately concentrated" to "highly concentrated." In volume terms, the shift was even more pronounced (from 1,743 to 5,602, +221%). This extreme concentration — with Turkey alone absorbing over 60% of exports — represents a significant vulnerability for EU exporters, as any disruption to the Turkish market (geopolitical tensions, regulatory changes, or demand shifts) could severely affect the sector.

Import concentration, by contrast, remained more stable. The import HHI by value moved from 2,564 to 2,628 (+2.5%), while the volume-based HHI actually declined from 4,072 to 3,101 (−23.8%), suggesting that import volumes became somewhat more diversified even as value concentration held steady. The rise of China offset the relative decline of traditional suppliers like Brazil and Saudi Arabia, keeping overall concentration relatively flat.

On the specialisation front, the Netherlands and France showed the strongest revealed comparative advantages within the EU (RSCA of 0.49 and 0.58 respectively), together accounting for over 42% of EU production value in this category. By contrast, member states such as Luxembourg, Ireland and Greece showed no measurable specialisation in acyclic ether production.

3. Sub-Product Divergence, Price Declines, and Supply Shocks

3.1 Import unit prices fell by 22%, driven by competition from new suppliers

Across the period, EU import unit prices for CN 290919 declined from €1,007 per tonne to €784 per tonne (−22.2%), with the trough of €784 reached in 2025. This sustained decline reflects the growing weight of lower-cost suppliers — most notably China — in the EU import basket. As Chinese volumes surged (from negligible levels to dominant market share), they exerted downward pressure on average import prices.

Export prices, by contrast, proved more resilient, declining only 1.5% (from €919/t to €905/t). Export prices were considerably more volatile, however, swinging from a low of €591/t in one year to a high of €1,248/t in another, driven largely by shifts in product mix and destination composition. The concentration of exports toward Turkey — where unit prices may differ from former destinations like the United States or Mexico — contributed to this variability.

Among import sources, coefficient of variation figures highlight which partnerships were most unstable: India (CV 2.56), China (1.91), the United States (1.56), and Japan (1.56) showed the highest price volatility on the import side. On the export side, Mexico (1.46), Singapore (1.52), and Ukraine (1.48) were the most volatile destinations.

3.2 Non-ETBE acyclic ethers drove the import surge; ETBE trade proved highly volatile

CN 290919 bundles two distinct sub-products whose trade trajectories diverged significantly over the period:

The non-ETBE segment (29091990) was the primary driver of the import surge. Import volumes for this sub-product grew from 241,000 tonnes to 949,000 tonnes (+293%), and its share of total import volume rose from 55.8% to 80.3%. In value terms, non-ETBE imports grew from €285 million to €721 million (+154%), with unit prices declining from €1,180/t to €761/t.

ETBE (29091910), a biofuel blending component whose trade is closely tied to energy policy and renewable fuel mandates, showed more moderate import growth (+22% in volume) but extreme export volatility. ETBE exports spiked dramatically in 2018 — reaching 137,569 tonnes and €113 million, up from just 27,566 tonnes the year before — before collapsing to 3,288 tonnes by 2025. This spike likely reflected a temporary surge in demand from markets adjusting to renewable fuel blending requirements. By 2025, ETBE had become a negligible export item (0.7% of total export value).

On the production side, the divergence between physical volumes and values is consistent with the EU focusing its domestic capacity on higher-margin derivatives while sourcing bulk acyclic ethers from international markets.

3.3 Isolated price shocks affected specific bilateral relationships

The supply shock analysis identified three notable price disruptions during the period:

The United Kingdom import price shock of 2018 — with an abnormality score of 12,212 and a near-doubling of unit prices — stands out as the most significant disruption. This coincides with the period of intense Brexit uncertainty and pre-departure stockpiling, during which trade patterns between the EU and UK became highly distorted. The sharp price increase may reflect rush orders at premium prices or a shift in the product mix toward higher-value UK-sourced ethers.

The Mexico export price shock of 2020 (+358.3%) occurred during the first year of the COVID-19 pandemic, when global logistics were severely disrupted and demand patterns shifted abruptly. Given that Mexican imports of EU acyclic ethers subsequently collapsed (from €50 million in 2015 to under €1 million by 2025), this shock may mark the beginning of a structural market loss rather than a temporary disruption. The Switzerland shock of 2022 (+54.9%) coincided with the broader European energy crisis and may reflect increased demand for chemical intermediates in the Swiss pharmaceutical and specialty chemicals sectors.

Conclusion

The EU trade in acyclic ethers (CN 290919) underwent a structural transformation between 2015 and 2025, characterised by three interconnected dynamics. First, import volumes nearly tripled while exports stagnated, converting a balanced trade position into a €505 million deficit. Second, the geographic landscape was reshaped around two poles: China emerged from near-irrelevance to dominate 41% of EU imports, while Turkey consolidated its grip on 61% of EU exports — creating a highly concentrated and potentially fragile export structure. Third, the non-ETBE segment drove the bulk of the import growth at steadily declining prices, while ETBE trade proved volatile and policy-sensitive. The EU's domestic production responded by shifting toward higher-value output, but this was insufficient to offset the growing import penetration in volume terms. Looking ahead, the extreme concentration of exports toward Turkey and the dominance of China in imports present both opportunities and vulnerabilities that merit close monitoring.
