Market evolution: Halogenated hydrocarbons (CN 2903) — 2015–2025

Introduction

Between 2015 and 2025, the European Union’s trade in halogenated derivatives of hydrocarbons (CN 2903) underwent a profound transformation. While the physical volume of exports increased and that of imports shrank, the trade balance in value terms deteriorated sharply because import prices soared and export prices fell. This report unpacks the main dynamics behind these diverging trends by examining price vs. volume shifts, the changing product mix towards high‑value fluorinated substances, and the evolving geography of both imports and exports. All figures are drawn from the EU trade dashboard for product 2903.

1. Diverging price trajectories reshape the trade balance despite growing net export volumes

Import prices surge while export prices erode

The most striking feature of the period is the opposite direction of unit prices on the two sides of trade. The average import price of halogenated hydrocarbons rose from EUR 1 282/tonne in 2015 to EUR 3 002/tonne in 2025, an increase of 134.1 %. In contrast, the average export price dropped from EUR 863/tonne to EUR 710/tonne, a decline of 17.8 % (based on overview trade data). This fundamental divergence is the main driver of the worsening value balance.

Volume trends point to an EU net exporter position in physical terms

Measured in physical quantities, the EU became a growing net exporter of halogenated hydrocarbons. Export volume expanded by 12.4 %, while import volume contracted by 43.5 %. As a result, the net‑import reliance ratio (computed from physical flows and domestic production) fell from –6.6 % in 2015 to –10.5 % in 2024 – the most recent year for which production data are available – indicating that the EU’s net export position deepened (see net import reliance).

The trade deficit widens as value divergence overwhelms volume gains

Despite the physical net export surplus, the monetary trade balance swung from a deficit of EUR 63 mn in 2015 to EUR 348 mn in 2025 – a worsening of 451.7 %. The ever‑higher unit cost of imported products, especially new‑generation fluorinated gases, more than offset the rising export tonnage and falling import tonnage. This value-versus-volume disconnect underscores a structural shift in the EU’s external positioning: the Union ships out large volumes of mature, lower‑priced chemicals while importing smaller, far more expensive specialty substances.

2. A structural shift towards high‑value fluorinated imports and mature chlorinated exports

Imports are dominated by costly HFOs and HFCs, while exports remain centred on ethylene dichloride and other chlorinated intermediates

The product‑level breakdown of trade reveals that the dramatic import price increase is driven by unsaturated and saturated fluorinated derivatives. For instance, imports of HFO‑1234yf and similar unsaturated HFOs (CN 290351) – a category that appeared in the data only from 2022 – rose from EUR 336 mn in 2022 to EUR 412 mn in 2025, with unit prices around EUR 19 000/tonne. The same dynamic is visible for HFC‑134a and HFC‑134 (CN 290345), whose import price climbed from EUR 5 236/tonne in 2022 to EUR 7 483/tonne in 2025. On the export side, the leading products by volume are lower‑unit‑price chlorinated compounds: ethylene dichloride (CN 290315) – with an export price that fell from EUR 188/tonne to EUR 141/tonne – and tetrachloroethylene, dichloromethane, and chlorobenzene (see product segment comparison).

The United States emerges as both the top supplier and a key customer, reflecting two‑way trade in specialty fluorochemicals

The United States became the EU’s single most dynamic partner. US imports into the EU rose from EUR 65.6 mn in 2015 to EUR 376.1 mn in 2025 (+473.1 %), while EU exports to the US grew from EUR 110.3 mn to EUR 176.4 mn (+59.9 %) (see top partners). This two‑way trade is strongly shaped by the exchange of high‑value fluorinated gases used in refrigeration and air‑conditioning, where US‑based multinationals play a dominant role.

China consolidates as a stable large‑scale supplier, while the United Kingdom’s role shrinks dramatically

China remained the largest single source by value throughout the period, with imports climbing from EUR 272 mn to EUR 351 mn (+29.2 %), although its share of total imports is now challenged by the US. In contrast, the United Kingdom – the top import source in 2018 – saw its shipments collapse from EUR 247 mn to EUR 91.5 mn (–49.2 %). The UK’s decline accelerated after 2021, with a severe volume contraction that drove import prices to levels above EUR 8 000/tonne in 2023, as documented in the shock analysis. Meanwhile, EU exports to the UK held relatively steady at around EUR 129 mn, making the UK a net importer from the EU.

3. Geographic concentration, price shocks, and the regional hub model

Export destinations become markedly more concentrated, while import sources remain moderately concentrated

The Herfindahl‑Hirschman Index for export destinations rose from 967 to 1 578 (+63.1 %), indicating that EU exporters are increasingly reliant on a small set of markets – notably the United States, the United Kingdom, and Türkiye (whose EU exports jumped by 117 % to EUR 66.2 mn). Import concentration, already moderate (HHI from 2 767 to 3 035, +9.7 %), edged higher but remains more diversified, thanks to multiple large suppliers (China, US, UK, Norway, India) (see concentration indicators).

Price shock events in UK imports and US/India/Egypt export flows underline the disruptive impact of policy shifts and supply constraints

The volatility analysis detects several extreme price episodes:

• UK import price shock (2023): a 1 045 % jump in unit value as import volumes plummeted to just 8 196 tonnes (from over 250 k tonnes earlier), suggesting a regulatory‑driven phase‑out or supply disruption.
• US export price spike (2022): a 56.9 % price rise coinciding with tightened global markets for fluorinated refrigerants.
• India and Egypt export price shocks (2018 and 2021): price increases of 125.8 % and 172.7 %, respectively, reflecting sudden demand or supply imbalances in specific chlorinated products (see volatility and shocks).

These events highlight the sector’s sensitivity to environmental regulations (the Kigali Amendment to the Montreal Protocol, REACH restrictions) and to logistical disruptions in concentrated supply chains.

Member‑state specialisation reveals a clear hub‑and‑spoke model centred on the Netherlands and Belgium

In 2025, the Netherlands and Belgium are the only EU countries with a revealed symmetric comparative advantage (RSCA) clearly above zero (0.406 and 0.5018, respectively), while traditional chemical powerhouses like Germany and France have RSCA values close to zero or slightly negative (see specialisation map). The Netherlands alone accounted for 52 % of EU imports of halogenated hydrocarbons in 2025, and 22 % of exports, acting as the main entry and exit port for fluorinated gases. This configuration suggests that the physical trade flows through a few logistical hubs (Rotterdam, Antwerp)ES, while production activities are more dispersed, though heavily concentrated in a handful of member states.

Conclusion

The 2015‑2025 period has reshaped the EU’s trade in halogenated hydrocarbons along three axes. First, a profound price divergence – import prices more than doubling while export prices steadily declined – transformed the EU from a slight net importer in physical terms into a net exporter that nonetheless faces a rapidly widening value deficit. Second, the product composition of imports has shifted decisively towards high‑value fluorinated gases (HFOs and HFCs), driven by climate‑friendly refrigerant regulations, whereas exports remain dominated by older chlorinated intermediates with low unit prices. Third, the geography of trade has become more concentrated, with the United States and China acting as the poles of the import side and the US, the UK and Türkiye serving as key export destinations, while intra‑EU specialisation funnels goods through the Benelux hubs. The combination of strong regulatory pressure, price volatility, and industrial re‑positioning will likely keep the sector on a trajectory of high‑value import dependence and mature commodity export, with persistent trade deficits in monetary terms.
