Market evolution: Saturated polyesters primary forms (CN 390799) — 2015–2025

Introduction

This report analyses the trade dynamics of the European Union (EU) in saturated polyesters in primary forms (excluding polycarbonates, alkyd resins, PET, and polylactic acid) classified under customs code 390799 over the period 2015 to 2025. The EU has been a consistent net exporter of this product category, though its trade balance has been under pressure. The period was characterised by significant growth in import volumes and values, particularly from Asia, while export growth was more modest. Key external shocks, including geopolitical events and price volatility, have reshaped trade patterns and partner relationships.

1. A Widening Trade Gap Amid Strong Import Growth

The EU's trade in CN 390799 has expanded, but import growth has substantially outpaced that of exports, leading to a compressed trade surplus. This dynamic is evident across both value and volume metrics.

Export growth lagged behind import dynamism

Between 2015 and 2025, the total value of EU exports increased by 27.1%, from €857.8 million to €1.09 billion. This growth was primarily price-driven, as the unit export price rose by 18.5% to €3,305 per tonne. In contrast, export volumes grew by only 7.3%, reaching 329,848 tonnes in 2025. This suggests EU exporters faced competitive pressures in global markets, relying more on price increases than on expanding market share.

Import surge eroded the EU's trade surplus

The growth in EU imports was far more pronounced. Import value rose by 47.3% to €877.2 million, driven almost entirely by a 47.8% increase in volume to 338,351 tonnes. The average import price remained stable (a marginal decline of 0.3%). Consequently, the EU's trade balance in this product shrank by 18.8% from a surplus of €262.3 million in 2015 to €212.9 million in 2025. This indicates that the EU's domestic market became increasingly reliant on foreign supply to meet demand.

2. Geopolitical and Competitive Shifts in Key Partnerships

The composition of the EU's main trading partners underwent significant changes, influenced by geopolitical events, supply chain adjustments, and divergent growth trajectories.

China became the EU's dominant source of imports

The most dramatic shift occurred in EU imports from China. Import value from China surged by 358% over the decade, rising from €42.4 million to €194.2 million, with China climbing to become the top supplier. This explosive growth highlights China's expanding production capacity and competitive pricing in the saturated polyester sector, significantly increasing its footprint within the EU market.

Exports to Russia collapsed following sanctions

EU exports to the Russian Federation experienced a severe contraction, plummeting by 67.4% from €59.4 million to €19.3 million. This collapse is a direct consequence of the sanctions regime implemented following 2022. Russia's share of EU exports diminished sharply, redirecting trade flows. Meanwhile, traditional partners like the United Kingdom (+45.7%) and the United States (+37.7%) remained strong export destinations.

Intra-EU production hub specialisation is pronounced

Within the EU, production and trade are highly specialised. Germany, Italy, and Belgium are the leading producing and exporting members, with Germany alone accounting for over 29% of EU production value. Conversely, countries like Ireland and Bulgaria show minimal specialisation in this product, indicating a concentrated industrial base within the bloc.

3. Market Structure, Price Volatility, and Strategic Implications

Underlying the top-line trade figures are important structural and operational dynamics, including rising production, price shocks, and evolving vulnerability profiles for the EU.

EU production capacity expanded to support trade

The EU's domestic production of CN 390799 grew robustly. Production volume increased by 19.9% to 1.09 million tonnes, while production value rose by 31.5% to €2.23 billion. This growth indicates ongoing investment and strong end-use demand within the EU, supporting its role as a major exporter despite rising imports.

2022 saw severe price shocks on key export routes

Trade in 2022 was marked by significant price shocks. Export prices to the United States spiked by 44.6%, and to the Russian Federation by 62.0%, in 2022. These events likely reflected the broader energy cost crisis and supply chain disruptions following the onset of the war in Ukraine, severely impacting trade economics that year.

The EU strengthened its export propensity, reducing net import reliance

Despite the growing trade balance pressure, the EU's position as a net exporter became more pronounced in proportional terms. The net import reliance ratio remained negative (indicating a surplus) and became more negative, moving from -6.5% to -7.9%. More strikingly, the export propensity (exports as a share of production) more than doubled from 25.3% to 53.6%. This indicates the EU industry has become significantly more export-oriented, with over half of its production now destined for non-EU markets.

Conclusion

The EU market for saturated polyesters (CN 390799) between 2015 and 2025 demonstrated resilience and transformation. The sector successfully expanded its production base and export orientation, maintaining a net surplus. However, this period also saw a strategic vulnerability emerge: a massive increase in imports from China, which now supplies a substantial portion of the EU's needs. The trade relationship with Russia was severed by geopolitical conflict, leading to a reorientation of exports towards stable partners like the UK and US. Looking forward, the EU industry's strong export propensity suggests competitiveness, but its growing import dependency on a single major supplier and past exposure to price shocks highlight key risks for supply chain stability and strategic autonomy in this key material sector.
