Market evolution: Coal tar distillation oils (CN 2707) — 2015–2025

Introduction

CN 2707 covers oils and other products of the distillation of high-temperature coal tar, along with similar products whose aromatic constituents outweigh the non-aromatic ones. This heading groups seven sub-headings, from benzene (270710) and toluene (270720) to creosote oils (270791) and residual coal-tar distillates (270799). These products serve as critical feedstocks for the chemical industry (aromatics for polymers, solvents, and intermediates) as well as for wood preservation and road-tar applications. Over the 2015–2025 period, the EU's trade profile for CN 2707 has been reshaped by three converging forces: surging domestic production and export capacity, a dramatic geopolitical realignment of supply chains following sanctions on Russia and Belarus, and sharp price cycles tied to the 2022 energy crisis. This report examines each of these dynamics in turn.

1. From Near-Balance to Dominant Net Exporter: The Structural Expansion of EU Capacity

1.1 The trade balance swung from a small deficit to a multi-billion-euro surplus

In 2015, EU extra-EU exports of CN 2707 stood at €1.91 billion against imports of €2.05 billion, leaving a modest trade deficit of €143 million. By 2025, exports had risen to €10.58 billion while imports reached €5.23 billion, producing a surplus of €5.35 billion. The net import reliance indicator flipped from −1.6% in 2015 to −136.6% in 2025, confirming that the EU is now a structurally large net exporter.

1.2 Export volumes grew more than fivefold

The quantitative expansion was even more striking than the value increase:

Export growth was predominantly volume-driven: quantities rose by 410% while unit prices gained only 8.6% over the full decade. Import growth, by contrast, was more price-sensitive — volumes rose 89% but values rose 155%, reflecting the post-2020 commodity-price upcycle.

1.3 Domestic production roughly tripled, underpinning export capacity

EU production of CN 2707 products (PRODCOM data) grew from 5.23 billion kg / €2.32 billion in 2015 to 12.31 billion kg / €6.55 billion in 2025 — an increase of 136% in volume and 183% in value. This expansion of domestic refining and chemical capacity was a prerequisite for the export surge: the export propensity rose from 44.7% to 179.2%, meaning that EU exports now far exceed domestic production in value terms — a pattern consistent with re-export and blending activity.

1.4 The residual coal-tar heading (270799) drove the export boom

Breaking exports down by sub-heading, the "other coal-tar distillation oils" category (270799) accounted for the overwhelming share of growth:

Sub-heading 270799 exports expanded from 1.72 Mt in 2015 to 21.22 Mt in 2025 (×12.3), absorbing nearly all of the overall volume growth. Meanwhile, 270750 (aromatic hydrocarbon mixtures ≥65% distilling at 250°C) saw its export volume fall from 2.65 Mt to 1.60 Mt, though it remains the second-largest export line by value. This structural shift suggests a reorientation of EU refinery and coal-chemical output toward higher-value-added residual blends for the Asian and Atlantic markets.

2. Geopolitical Realignment: Sanctions, Supplier Substitution, and Partner Diversification

2.1 Russian and Belarusian supply collapsed after 2022

The single most consequential dynamic in the import side was the disappearance of Russian supply. Russia was the EU's largest import partner in 2015, supplying €1.06 billion (52% of EU imports by value). Russian import values peaked at €2.80 billion in 2021, before falling to just €89,252 by 2025 — a near-total collapse of −100%. Belarus followed a similar trajectory, from €560 million at its peak to €2,306 in 2025 (−99.9%). This was driven by successive rounds of EU sanctions on Russian energy and petrochemical products following the invasion of Ukraine.

2.2 The UK, Türkiye, and the US filled the supply gap

The vacated Russian volumes were partly absorbed by a diversified set of new and growing suppliers:

• United Kingdom imports grew from €335 million to €1.71 billion (+411%), making the UK the EU's single largest import partner by 2025. Post-Brexit trade reorientation and geographical proximity facilitated this shift.
• Türkiye surged from €50 million to €695 million (+1,298%), reflecting Türkiye's expanding petrochemical capacity and its role as a bridge between Russian crude derivatives and EU markets.
• United States imports grew from €50 million to €374 million (+645%), coinciding with the ramp-up of US Gulf Coast aromatics capacity and the redirection of transatlantic energy flows after 2022.

2.3 Import concentration fell sharply

The Herfindahl–Hirschman Index (HHI) for EU imports by value fell from 3,772 (2015) to 1,843 (2025) — a decline of 51.1%. In volume terms, the HHI fell from 4,687 to 1,701 (−63.7%). In 2015, the market was moderately concentrated, with Russia alone accounting for over half of import value. By 2025, no single partner holds a dominant share, and the market structure approaches a competitive, diversified profile. This diversification reduces single-source vulnerability but introduces greater complexity in supply-chain management.

2.4 Export destinations also shifted dramatically

On the export side, the destination map was redrawn:

• China went from the EU's largest export partner (€621 million in 2015, peaking at €1.45 billion) to virtually zero by 2025 (€7.4 million, −98.8%), likely reflecting China's own capacity build-up in coal-chemical production.
• Singapore remained a significant destination (€479 M → €790 M, +65%), serving as a blending and trans-shipment hub for Asian markets.
• "Stores and provisions within the framework of extra-Union trade" (a statistical category capturing bonded-warehouse and free-zone flows) exploded from €1.6 million to €2.99 billion, suggesting a growing role for EU ports as intermediate storage and re-export platforms.
• Gibraltar and "Countries and territories not specified" also recorded very large increases (€16 M → €993 M and €1 M → €1,714 M respectively), partly reflecting statistical reclassification and partly the routing of shipments through intermediary jurisdictions.

The export-side HHI dropped from 1,960 to 945 (−51.8%), indicating an even more dispersed export structure than the import side.

2.5 EU Member State roles evolved unevenly

The reporter-level data reveals significant intra-EU shifts:

• Netherlands consolidated its position as the EU's main hub: imports grew from €556 M to €2,179 M (+292%) and exports from €1,009 M to €4,016 M (+298%), consistent with Rotterdam's role as the principal petrochemicals port.
• Belgium saw exports surge from €64 M to €2,197 M (+3,348%), likely driven by Antwerp's expanding aromatics cluster.
• Spain emerged as a major importer (€3 M → €1,037 M) and exporter (€218 M → €1,837 M), possibly linked to its refinery network and proximity to Mediterranean trade routes.
• Germany and Estonia — both historically significant — saw their import shares decline (Germany: €727 M → €266 M, −63%; Estonia: €85 M → €26 M, −69%), reflecting the loss of Russian pipeline flows that historically transited the Baltic.

3. Price Cycles, Energy-Crisis Shocks, and Volatility Patterns

3.1 Prices followed a three-phase cycle aligned with global energy markets

Unit prices for both imports and exports traced a distinctive trajectory over the decade:

Prices bottomed in 2020 amid the COVID-19 demand collapse, then surged to record highs in 2022 as the Russia–Ukraine conflict disrupted European energy and petrochemical supply chains. By 2025, prices had partially retraced but remained well above pre-crisis levels. The sub-heading 270750 (aromatic HC mixtures) import price peaked at €918/t in 2022, while 270799 reached €592/t — both more than double their 2020 troughs.

3.2 The 2022 energy crisis triggered the largest price shocks

The shock detection analysis identified three principal abnormal price events:

The Malaysian export-price shock in 2022 (abnormality score 22.8, shift +365.9%) stands out as the most extreme event: it likely reflects a short-lived, highly concentrated shipment at peak market prices during the acute phase of the European energy crisis. The Morocco shock in 2017, while significant in statistical terms, may reflect a thin-volume arbitrage event rather than a structural market disruption. The US import-price shock in 2022 (67% price shift) is more muted but directly linked to the broader energy-commodity repricing.

3.3 Volatility was highest for smaller, less predictable trade corridors

The coefficient of variation (CV) analysis reveals which partners exhibited the most erratic trade flows:

Highest-volatility import partners (CV):

Highest-volatility export partners (CV):

Partners with high CVs tend to be those with small or sporadic trade volumes (Belarus, Mexico, Panama) or those that experienced a dramatic rise-then-collapse pattern (China for exports). By contrast, the major steady-flow partners — the UK, US, and Singapore — all exhibited moderate CVs (0.43–0.73), indicating more predictable and structurally embedded trade relationships.

3.4 Price differentials between import and export unit values narrowed over the period

In 2015, the EU exported at €422/t against an import price of €391/t, a premium of €31/t (+7.9%). By 2025, the gap had widened slightly to €33/t (export €459 vs. import €526), but the relationship had inverted — imports were now more expensive than exports. This reflects the post-2022 cost structure: the EU was importing from more distant and higher-cost suppliers (US, Türkiye) while exporting large volumes of competitively priced residual coal-tar products (270799 at €444/t) to global markets. The sub-heading 270750, which represents a more refined product mix, commanded significantly higher prices on both the import (€667/t) and export (€628/t) sides in 2025.

Conclusion

Over the decade 2015–2025, the EU trade in CN 2707 products underwent a fundamental transformation. A near-balanced market gave way to a dominant export position, with extra-EU exports rising to €10.6 billion and the trade surplus reaching €5.4 billion. This was powered by a more than doubling of domestic production and a twelve-fold increase in exports of residual coal-tar distillation oils (270799). The geopolitical rupture of 2022 — with EU sanctions effectively eliminating Russian and Belarusian supply — forced a rapid diversification of import sources toward the UK, Türkiye, and the United States, cutting the import-side HHI nearly in half. Price dynamics were dominated by the 2020 trough and the 2022 energy-crisis spike, with unit values peaking at around €658/t on the import side before partially normalising. Looking ahead, the EU's structural shift from net importer to net exporter positions it as a key global supplier of coal-tar-derived aromatics, though continued price volatility and the evolving sanctions landscape will remain central risks to monitor.
