Market evolution: Linear low density polyethylene (CN 39011010) — 2015–2025

Introduction

This report analyses the EU's external trade in linear low-density polyethylene (LLDPE) over the period 2015–2025. The data reveals a decade marked by a significant contraction in trade volumes and values, shifting partner dynamics, and a notable decline in the EU's export orientation. This transformation reflects broader global supply chain adjustments, regional production shifts, and periods of market volatility, particularly around 2021.

I. A Decade of Contraction: Significant Decline in EU Trade Volumes and Values

The most striking feature of the 2015–2025 period is the pronounced decline in both the value and quantity of the EU's trade in LLDPE. This contraction is visible across imports and exports, indicating fundamental changes in the market.

EU exports more than halved in value and volume

The EU's exports of LLDPE to non-EU countries fell dramatically. The trade overview shows export value decreased from approximately €497 million in 2015 to €208 million in 2025, a decline of 58.1%. Export quantity fell by 52.2%, from 339,861 tonnes to 162,391 tonnes. This sustained drop suggests a loss of competitiveness, a redirection of production for domestic use, or the impact of new production capacity outside the EU.

EU imports also contracted, but from a higher base

While the EU remained a net importer, its import values also contracted significantly. Import value decreased from approximately €1.19 billion to €669 million (-43.9%), and quantity fell from 1.03 million tonnes to 653,473 tonnes (-36.3%). The decline was less severe than for exports, meaning the EU's net import reliance only improved slightly, from 16.7% to 15.7%. The EU's trade intensity (the sum of exports and imports relative to production) fell sharply from 44.3% to 29.9%, confirming the market became less internationally engaged.

Unit prices exhibited cyclical behaviour followed by a recent decline

Average unit prices for both imports and exports followed a similar trajectory: a rise to a peak around 2021–2022, followed by a retreat. Import prices reached a maximum of €1,557 per tonne, while export prices peaked at €1,686 per tonne. By 2025, prices had declined to €1,024 and €1,283 per tonne respectively, ending the period slightly lower than in 2015. This pattern aligns with the global post-pandemic commodity price surge and subsequent normalization.

II. Shifting Partners and Volatility: Geographic Re-alignment and Price Shocks

The contraction in trade was accompanied by a major reshuffling of the EU's key trading partners for LLDPE. Traditional partners lost ground, while others gained prominence, leading to changes in supply concentration.

Saudi Arabia's dominance in EU imports collapsed, while US shipments surged

The partner analysis reveals a dramatic shift. Saudi Arabia, the top import source in 2015 (€561 million), saw its exports to the EU plummet by 86.7% to €74 million by 2025. Conversely, imports from the United States grew by 129.7%, from €100 million to €229 million, making it the top source by value in the final year. Imports from the United Kingdom also collapsed post-Brexit. This diversification reduced the import concentration HHI from 3,020 to 1,944.

The UK's role as the EU's primary export destination diminished sharply

For exports, the United Kingdom remained the largest destination but its share eroded severely. Exports to the UK fell from €204 million to €59 million (-70.8%). Exports to Türkiye and the Russian Federation also declined substantially, with shipments to Russia nearly ceasing by 2025 (-97.6%). This contraction in key traditional markets underscores a significant re-orientation of EU export flows.

Significant price shocks were detected in 2021, especially for UK trade

The data identifies periods of high volatility. Several supply shock events are centred on 2021. The most severe was an import price shock from the United Kingdom, with a year-on-year price increase of 116.9% and an abnormality score of 10.8. A notable export price shock was also recorded for Switzerland (+38.2%). These events likely reflect post-Brexit trade disruption and the 2021 global energy and logistics crisis.

III. Structural Shifts: Divergent National Specialisations and Declining Export Capacity

Beyond aggregate trade flows, the structure of the EU's LLDPE sector itself underwent changes, with production values rising slightly even as volumes fell, and a pronounced drop in the bloc's ability to export its output.

Domestic production volumes declined while values held steady

EU production of LLDPE, as reported via ProdCom, saw a decrease in quantity of 14.3% (from 2.33 billion kg to 2.00 billion kg) but a small increase in value of 6.0% (from €2.13 billion to €2.26 billion). This indicates a move towards producing higher-value grades or reflects inflationary pressures, even as physical output contracted.

Belgium, Finland, and Spain emerged as specialised producers within the EU

An analysis of national specialisation for 2025 shows Belgium with a high Revealed Symmetric Comparative Advantage (RSCA) of 0.65, indicating it is a highly specialised exporter of this product. Finland (RSCA 0.39) and Spain (RSCA 0.35) also displayed clear specialisation. In contrast, countries like Cyprus and Romania showed significant negative specialisation, meaning they are net importers of this product relative to their overall trade.

The EU's export propensity collapsed, signalling a major structural shift

Perhaps the most telling indicator is the EU's export propensity—the share of domestic production that is exported. This metric experienced a dramatic decline from 21.3% in 2015 to just 9.9% in 2025, a fall of 53.5%. This sharp drop, the most salient metric in the autonomy and vulnerability assessment, indicates that the EU's LLDPE industry has re-focused inward, serving the internal market rather than international customers.

Conclusion

The EU's trade in linear low-density polyethylene between 2015 and 2025 was characterized by substantial contraction, geographic re-orientation, and a fundamental inward shift. Both exports and imports fell significantly in volume and value, though the EU remained a net importer. The landscape of trading partners was redrawn: Saudi Arabia's role collapsed, the US strengthened its position, and Brexit severely impacted UK-EU trade flows. While the EU maintained some specialised producers, its overall capacity and willingness to export this product diminished markedly. The market became less internationally integrated, with a halving of its export propensity, suggesting a strategic pivot towards serving European downstream industries rather than competing globally.
