Market evolution: Polycarbonate resins (CN 390740) — 2015–2025

Introduction

This report examines the evolution of the European Union's external trade in polycarbonates in primary forms (Combined Nomenclature code 390740) over the 2015–2025 period. Polycarbonates are high-performance engineering thermoplastics widely used in automotive, electronics, construction, and optical applications. The EU has historically been both a significant producer and exporter of these resins, but the data reveals a decade of profound structural transformation. The EU's trade position has shifted from a comfortable surplus to near-parity with imports, driven by declining exports, surging inbound shipments—particularly from Asia—and a contraction in domestic production. This report identifies and interprets the main dynamics behind this transformation.

The analysis draws on EU-level trade statistics covering general trade flows and partner shares, concentration and specialisation indicators, supply-shock detection, and vulnerability metrics.

1. The erosion of EU competitiveness: exports in secular decline

1.1 Export volumes and values contracted sharply over the decade

EU exports of polycarbonates to non-EU countries fell from 261,765 tonnes (€587 million) in the first observed year to 188,530 tonnes (€369 million) in the last, representing declines of 28.0% in volume and 37.1% in value. Export unit values also fell by 12.7%, from €2,243/t to €1,959/t. The export value peak was reached around the midpoint of the period at €734 million, after which a persistent downtrend set in. This three-way erosion—in quantity, value, and price—points to a structural loss of market share rather than a cyclical fluctuation.

1.2 Traditional export markets contracted most dramatically

The decline was not evenly distributed across destination markets. Exports to China—the EU's single largest polycarbonate export destination—fell by 44.5% (from €201 million to €111 million). South Korea collapsed by 90.8% (from €27 million to just €2.5 million), India by 71.5% (from €54 million to €16 million), and Israel by 82.3% (from €16 million to €3 million). These losses reflect the rapid build-up of indigenous polycarbonate capacity in Asia, particularly in China and South Korea, which progressively displaced EU-origin material.

A few markets bucked the trend: exports to the United Kingdom grew by 62.8% (to €45 million) and to Switzerland by 69.9% (to €36 million), likely benefiting from geographic proximity and, in the UK's case, post-Brexit trade reorientation.

1.3 Within the EU, export capacity shifted from Spain toward the Netherlands and Italy

Among EU Member States, Spain was by far the largest exporter at the start of the period (€336 million), but its shipments collapsed by 74.8% to just €85 million. The Netherlands remained a substantial exporter (€178 million, down 8.2%), while Italy's exports nearly doubled (from €31 million to €59 million). Poland emerged as a notable new exporter, growing from €2 million to €11 million (+418%). The shift suggests a geographical reorientation of EU production and re-export activity.

2. The Asian import surge: Korea and China reshape EU supply

2.1 EU imports more than doubled in volume, while prices fell

In stark contrast to exports, EU imports of polycarbonates surged from 91,903 tonnes (€206 million) to 220,342 tonnes (€393 million)—an increase of 139.8% in volume and 90.4% in value. Notably, import unit prices fell by 20.6%, from €2,244/t to €1,782/t, indicating that the additional supply entered at significantly lower price points than historical norms. This price compression is a hallmark of capacity-driven competition from low-cost producers.

2.2 South Korea became the dominant supplier, while China's growth was explosive

South Korea was already the largest import partner in the first year (€72 million) and grew to €188 million (+159.2%), reaching a peak of €218 million during the period. China's rise was even more dramatic: from a modest €5 million, Chinese imports exploded to €70 million—a staggering 1,334% increase. Together, these two countries accounted for the bulk of the import growth. Traditional suppliers like the United States (−21.8%) and Saudi Arabia (−1.8%) stagnated or declined, while Taiwan (+77.2%) and Japan (+8.9%) maintained moderate growth.

2.3 The trade balance flipped from surplus to near-deficit

The EU's trade balance in polycarbonates deteriorated from a surplus of €381 million to a small deficit of −€24 million—a swing of 106.2%. The net import reliance indicator confirms this trajectory: from −20.5% (strong net exporter) to −0.6% (effectively balanced), a 97.2% shift toward import dependence. The EU has gone from being a clear net exporter to a position where imports nearly match exports.

Within the EU, the import surge was absorbed by several Member States. Italy's imports grew from €27 million to €88 million (+223%), Hungary's from €3 million to €55 million (+1,926%), and Poland's from €11 million to €54 million (+374%). These countries likely host downstream converting industries that increasingly source feedstock from Asian producers.

3. Rising concentration and supply-chain vulnerability

3.1 Import sources became significantly more concentrated

The Herfindahl-Hirschman Index (HHI) for EU polycarbonate imports by value rose from 1,798 to 2,793 (+55.4%), crossing into territory that trade economists typically regard as moderately concentrated. By volume, the HHI climbed even faster, from 1,951 to 3,446 (+76.6%). This increasing concentration reflects the growing dominance of South Korea and China as suppliers. In a supply disruption scenario—whether from geopolitical tensions, logistics bottlenecks, or production outages—the EU's exposure to a small number of Asian origins represents a tangible vulnerability.

By contrast, export destinations became slightly less concentrated (HHI fell from 1,478 to 1,333), reflecting the diversification away from declining Asian markets toward the UK and Switzerland.

3.2 Price shocks underscore supply-side fragility

The shock detection analysis identified several significant price anomalies. The most prominent was a 51.9% price shift in imports from South Korea centred on 2021, with an abnormality score of 7.8—likely linked to the global petrochemical supply disruptions of the COVID-19 recovery period. Imports from the United States exhibited a 40.7% price shock in 2017 (abnormality 8.8). On the export side, a notable price anomaly appeared in shipments to Morocco in 2022 (+29.9%, abnormality 9.1). These events highlight the price volatility inherent in a market increasingly reliant on long-distance, concentrated supply chains.

Among import partners, China exhibited the highest overall volatility (coefficient of variation of 1.25), followed by Russia (1.39), reflecting the boom-and-bust nature of flows from these origins. Among export partners, South Korean-bound shipments showed high volatility (CV 0.76), consistent with the near-complete collapse of that trade flow.

3.3 Domestic production contracted, narrowing the export base

EU production volumes fell from 1.13 billion kg to 878 million kg (−22.3%), while production value declined more modestly from €2.62 billion to €2.50 billion (−4.8%). The divergence between volume and value declines suggests that EU producers retained some pricing power in domestic and intra-EU markets, but the shrinking output base directly underpins the export decline documented above. The EU's export propensity fell from 24.8% to 15.4% (−37.8%), confirming that a smaller share of EU production is being directed to external markets.

The specialisation data shows that Spain (RSCA 0.57), Hungary (0.47), Italy (0.42), and the Netherlands (0.41) remain the most specialised EU polycarbonate exporters, while Belgium, Greece, Bulgaria, and Croatia have essentially no export specialisation in this product. The concentration of export capability in a handful of Member States adds a geographical dimension to the EU's vulnerability.

Conclusion

Over the 2015–2025 decade, the EU's position in global polycarbonate trade underwent a fundamental transformation. From a comfortable net exporter with a €381 million trade surplus, the EU moved to near-zero balance, as exports contracted by 28–37% while imports surged by 90–140%. The primary driver was the rapid expansion of Asian production capacity—particularly in South Korea and China—which simultaneously displaced EU exports in third markets and penetrated the EU domestic market at progressively lower prices. EU domestic production declined by over 20%, reinforcing the export contraction.

This structural shift carries implications for supply-chain resilience. Import concentration has risen sharply (HHI +55% by value), leaving the EU increasingly dependent on a small number of Asian suppliers. While the EU retains specialised production clusters in Spain, the Netherlands, Italy, and Hungary, the erosion of export propensity—from 24.8% to 15.4%—suggests a diminishing role in global polycarbonate markets. Policymakers and industry stakeholders may wish to monitor these trends closely, particularly in the context of strategic autonomy objectives for critical materials and advanced manufacturing inputs.
