Market evolution: Propylene copolymers (CN 390230) — 2015–2025

Introduction

Propylene copolymers in primary forms (CN 390230) are versatile engineering plastics used across packaging, automotive, medical devices, and consumer goods. As a sub-category of propylene polymers, they occupy a strategically important position in the European chemicals value chain. Over the 2015–2025 decade, the EU's external trade in this product underwent a profound transformation: the bloc's trade surplus shrank by 42.9%, export volumes declined by 21.9%, and import volumes surged by 92.9%. Meanwhile, the geography of trade was reshuffled by geopolitical events—including Brexit and the Russia sanctions—while EU domestic production grew by a third. This report examines these dynamics across three sections, analyzing the erosion of the EU's trade surplus, the realignment of trade partnerships, and the structural vulnerabilities that have emerged in the process.

1. The Erosion of the EU's Trade Surplus: Declining Exports Meet Surging Imports

Export volumes contracted by over 20% despite a steady rise in unit prices

The EU's external exports of propylene copolymers declined from 1,005,062 tonnes in 2015 to 784,670 tonnes in 2025—a drop of 21.9%. In value terms, the decline was more moderate, from €1.44 billion to €1.33 billion (−7.4%), because unit export prices rose from €1,435/t to €1,701/t (+18.5%). This price resilience suggests that EU producers increasingly focused on higher-value or specialty grades rather than commodity volumes. However, the persistent volume decline points to a loss of competitiveness in price-sensitive international markets.

Import volumes nearly doubled, with unit prices trending downward

In parallel, EU imports surged from 302,840 tonnes to 584,066 tonnes (+92.9%) in volume, and from €451 million to €769 million (+70.4%) in value. Crucially, import unit prices actually fell from €1,490/t to €1,316/t (−11.7%), making imported copolymers increasingly competitive. The widening gap between export prices (€1,701/t) and import prices (€1,316/t) points to a growing market segmentation: the EU exports specialised, higher-margin grades while importing more commoditized products at lower cost.

The EU's trade surplus shrank by over 40%, signalling a structural market shift

The combined effect of falling exports and surging imports was a dramatic erosion of the EU's trade balance. From a surplus of €991 million in 2015, it fell to €566 million in 2025—a contraction of 42.9%. The net import reliance ratio, although still negative (confirming the EU remains a net exporter), moved from −249% to −39%, indicating a fundamental weakening of the EU's net exporter position. This trajectory was not a cyclical fluctuation; it reflects a structural repositioning of the EU in global propylene copolymer trade, driven by competitive pressures from Asia and the Middle East.

*The positive percentage change reflects the reduction in magnitude of the EU's net exporter position—i.e., the EU moved closer to import–export balance.

2. A Geopolitical Reshuffling of Trade Partnerships

South Korea became the EU's dominant import supplier, accounting for nearly 40% of inflows

The most striking shift on the import side was the rise of South Korea. Korean exports of propylene copolymers to the EU surged from €69 million in 2015 to €306 million in 2025—an increase of 342.5%. By 2025, South Korea alone accounted for approximately 40% of all EU imports by value, up from roughly 15% a decade earlier. The United States (+139.9%), Saudi Arabia (+66.0%), and Israel (+88.9%) also gained ground, reflecting the growing competitiveness of petrochemical producers in North America and the Middle East. Brazil, by contrast, saw its exports to the EU collapse by 81.2%.

EU exports to Russia collapsed entirely following 2022 geopolitical events

On the export side, the most dramatic change was the disappearance of Russia as a destination market. EU exports to Russia fell from €81 million in 2015 to essentially zero by 2025 (−100%), a direct consequence of the sanctions regime imposed following 2022. This loss was only partially offset by gains elsewhere: China (+48.9%) and Brazil (+8.8%) absorbed some redirected volumes, while Switzerland (+13.9%) and the United States (+4.2%) remained relatively stable. Türkiye, the second-largest export destination, held nearly flat at approximately €263 million, confirming its role as a key and resilient market for EU producers.

United Kingdom trade flows contracted sharply on both sides of the Channel

The United Kingdom—historically the EU's largest single export market for propylene copolymers and a significant import source—saw its trade with the EU decline on both fronts. Exports to the UK fell from €404 million to €271 million (−33.0%), while imports from the UK plunged from €120 million to €33 million (−72.2%). This bilateral contraction is consistent with the trade-friction effects of Brexit, including new customs procedures, rules-of-origin requirements, and regulatory divergence that raised the cost of cross-Channel chemicals trade. The UK's share of EU imports fell from approximately 27% in 2015 to just 4% in 2025.

3. Rising Import Concentration and Emerging Supply Vulnerabilities

Import-side concentration increased markedly while export markets diversified

The Herfindahl-Hirschman Index (HHI) for EU imports rose from 1,417 to 2,001 by value (+41.2%) and from 1,479 to 2,496 by volume (+68.8%). An HHI above 2,000 signals moderate-to-high concentration, meaning the EU's import supply base has become significantly less diversified—driven primarily by the dominance of South Korea. In sharp contrast, export-side concentration fell: the export HHI decreased from 1,286 to 1,055 by value (−18.0%), indicating that EU producers successfully diversified their customer base across more destination markets.

This asymmetry—a concentrating import base alongside a diversifying export base—creates a structural imbalance. While EU producers spread their risk across more destination markets, the bloc's inbound supply became increasingly reliant on fewer partners, raising vulnerability to supplier-specific disruptions.

EU production expanded strongly, yet export propensity declined significantly

Despite the trade headwinds, EU domestic production of propylene copolymers grew substantially—from 1.52 billion kg to 2.01 billion kg in volume (+32.9%) and from €1.44 billion to €3.05 billion in value (+111.4%). The near-doubling of production value, far outpacing the volume increase, reflects the energy-price inflation that swept through European petrochemicals in the 2021–2023 period. Yet this production growth did not translate into export gains. Instead, export propensity—the share of production exported—fell from 95.8% to 67.3%, while trade intensity declined from 96.6% to 76.5%. A growing share of EU production was absorbed by the internal market, even as the EU simultaneously imported more from third countries—suggesting robust and growing European demand for these materials.

Within the EU, specialisation patterns remained concentrated: Belgium (RCA of 3.99, accounting for 33.8% of EU production), the Netherlands (15.7%), and France (8.7%) dominated output. On the import side within the EU, Italy (+276%) and Greece (+254%) recorded the largest increases in inbound volumes, suggesting a geographic shift of import entry points toward Southern Europe.

Price shocks in key trade corridors exposed the fragility of the EU's position

The volatility analysis reveals that several of the EU's trade relationships exhibited high instability. On the import side, Vietnam (CV: 1.15), Brazil (CV: 0.76), and South Africa (CV: 0.65) showed the most erratic supply patterns. On the export side, flows to Russia (CV: 0.52) were volatile even before the complete collapse, while Israel (CV: 0.41) and the United States (CV: 0.34) also showed significant year-to-year swings. Three notable price shock events were detected:

• China (exports, 2020): a 34.9% price spike with an abnormality score of 16.8, likely linked to pandemic-era demand shifts.
• Singapore (imports, 2022): a 32.3% price surge (abnormality: 15.3), coinciding with the global energy-price crisis.
• United States (exports, 2023): a 158.4% price shock (abnormality: 8.4), potentially reflecting supply-chain reconfiguration and arbitrage effects.

These episodes underscore the vulnerability of EU trade flows to supply-chain disruptions, energy-price transmission, and sudden demand shifts—vulnerabilities that are amplified by the rising concentration of the import base.

Conclusion

Over the 2015–2025 decade, the EU's position in global propylene copolymer trade shifted from that of a dominant net exporter with a near-€1 billion surplus to a more balanced—and increasingly import-dependent—market actor. Export volumes fell by over 20%, while import volumes nearly doubled, eroding the trade surplus by 43%. Geopolitical events reshaped the geography of trade: South Korea emerged as the overwhelmingly dominant import supplier (accounting for nearly 40% of EU imports by 2025), Russia disappeared entirely as an export destination following sanctions, and UK–EU trade contracted sharply on both sides following Brexit. Meanwhile, EU domestic production grew strongly in volume and especially in value, but this growth served the internal market rather than reinforcing export competitiveness. The concentration of imports into fewer supplier countries, combined with episodes of pronounced price volatility in key corridors, points to emerging supply-side vulnerabilities. For EU policymakers and industry stakeholders, these trends raise important questions about strategic autonomy in a critical segment of the plastics value chain.
