Market evolution: Plastic closures (CN 39235090) — 2015–2025

Introduction

This report examines the evolution of EU trade in plastic stoppers, lids, caps, and other closures (excluding caps and capsules for bottles) classified under CN 39235090 over the period 2015–2025. The European Union is a net exporter of these products, and the decade under review has been marked by sustained growth in both trade flows and domestic production. However, beneath the headline expansion lie significant shifts in partner geography, rising import prices, and a notable concentration of import sourcing toward a smaller number of suppliers — most notably China. This report is structured around three principal themes: the overall growth trajectory and the divergence between volume and value dynamics; the reshaping of trade partnerships and supply-source geography; and the EU's structural positioning in terms of autonomy, vulnerability, and comparative advantage.

I. A Decade of Value-Driven Growth Outpacing Physical Volume

EU exports grew by half in value but only modestly in quantity

Between 2015 and 2025, EU exports of plastic closures to non-EU countries rose from €644.7 million to €969.2 million, representing a cumulative increase of +50.3%. Over the same period, the exported quantity grew from 111,847 tonnes to 126,488 tonnes, an increase of only +13.1%. This divergence implies a substantial rise in unit export prices, which climbed from €5,764/t to €7,661/t (+32.9%). The EU's export growth in this product category was therefore predominantly value-driven, reflecting either a shift toward higher-value-added closures, general input-cost inflation (particularly in plastics and energy post-2021), or a combination of both.

Import growth was even more pronounced, particularly in monetary terms

EU imports from non-EU countries grew even more rapidly: the import bill rose from €428.2 million to €753.6 million, an increase of +76.0%. Physical import volumes grew from 79,956 tonnes to 94,973 tonnes (+18.8%). Unit import prices rose from €5,354/t to €7,935/t, an increase of +48.2% — substantially steeper than the corresponding rise in export prices. This price asymmetry is significant: it suggests that the EU's import basket has experienced greater cost pressure than its export basket, potentially eroding the cost advantage of foreign suppliers.

The trade surplus remained stable despite faster import growth

Despite imports growing faster than exports in value terms, the EU maintained a trade surplus throughout the entire period. The surplus stood at €216.5 million in 2015 and at €215.6 million in 2025, a decline of just −0.4%. The surplus peaked at €303.6 million at some point during the decade and was at its lowest at €193.4 million. This resilience indicates that the EU's competitive position in plastic closures — while not accelerating — has been broadly preserved.

Domestic production expanded significantly in both volume and value

EU domestic production of plastic closures (as captured by Prodcom 22.22.19.25) increased from 1,922,271 tonnes to 2,200,000 tonnes (+14.4%) in quantity, and from €5,494 million to €7,669 million (+39.6%) in value. Production peaked at approximately 2,565,000 tonnes and €8,000 million in value during the decade. The faster growth in production value compared to volume mirrors the price dynamics observed in trade and confirms that inflation in plastics-related inputs and energy costs has been a structural feature of the 2015–2025 period.

II. Geographical Shifts: China's Rise and Russia's Decline

China became the dominant extra-EU supplier, more than tripling its share

The most striking development on the import side was the dramatic expansion of China's role. EU imports from China surged from €109.8 million to €295.8 million, an increase of +169.3%. China is now by far the EU's largest non-EU supplier of plastic closures, accounting for approximately 39.1% of the import value in 2025. This expansion reflects China's continued cost competitiveness in plastics manufacturing, its integration into European packaging supply chains, and potentially the redirection of trade flows following Brexit-related disruptions.

The United Kingdom lost ground as an import source post-Brexit

The United Kingdom, which was the EU's second-largest import source in 2015 at €109.8 million, saw its exports to the EU fall to €94.0 million by 2025 (−14.4%). This decline is consistent with the well-documented trade friction introduced by Brexit, including customs formalities and regulatory divergence. However, the UK remained the EU's largest export destination, absorbing €166.3 million of EU exports in 2025 (+35.6% from 2015), indicating that the EU retained a strong competitive edge in supplying the UK market.

Türkiye and Serbia emerged as fast-growing trade partners

Two other partner countries showed exceptionally rapid growth:

These figures suggest a deepening of EU–Western Balkan and EU–Türkiye plastics supply-chain integration, likely driven by proximity advantages, EU accession or association frameworks, and cost competitiveness relative to Western European producers.

EU exports to Russia collapsed following geopolitical events

EU exports to the Russian Federation declined from €42.9 million to €19.6 million (−54.4%), with the minimum during the period reaching €19.6 million. This sharp contraction aligns with the EU sanctions regime imposed following Russia's invasion of Ukraine in 2022. The volatility coefficient for this trade flow was the highest among all major export partners at 0.361, confirming the instability introduced by the geopolitical rupture.

Import concentration increased while export markets remained diversified

The Herfindahl-Hirschman Index (HHI) for import concentration by value rose from 1,833 to 2,146 (+17.0%). While this remains below the conventional 2,500 threshold for a "highly concentrated" market, the upward trend signals a meaningful reduction in supplier diversity — driven primarily by China's growing dominance. By contrast, the HHI for export concentration by value declined slightly from 764 to 726 (−5.0%), indicating that EU exports remained well-diversified across destination markets.

III. Autonomy, Vulnerability, and Structural Positioning

The EU maintained a net-exporter position throughout the decade

The net import reliance ratio remained negative throughout the period, confirming the EU's status as a net exporter. It moved from −9.9% in 2015 to −6.0% in 2025, a narrowing of 39.5%. While the EU remained a net exporter, this convergence indicates that imports have been growing faster than the domestic market, slightly reducing the EU's relative self-sufficiency. The trend warrants monitoring, particularly given the rising import concentration toward China.

Export propensity declined, suggesting a gradually more inward-looking market

The export propensity — measured as exports relative to production — fell from 19.5% to 18.0% (−7.5%) over the period. This suggests that a slightly larger share of EU production is being absorbed domestically rather than exported. Trade intensity (the ratio of total trade to total production including trade) remained essentially flat at approximately 27.0%.

France, Spain, and Poland emerged as the most specialized EU producers

The specialisation analysis for 2025 reveals a clear tiering of EU member states:

France stands out with an RCA above 2 and a symmetric comparative advantage (RSCA) of 0.39, indicating a strong and persistent specialization in plastic closures. At the other end, countries such as Cyprus (RCA 0.008) and Romania (RCA 0.12) show no comparative advantage in this product category.

Price shocks in 2022 reflect the broader macroeconomic turbulence

The shock detection analysis identified the most significant event as a price shock in EU imports from China in 2022, with an abnormality score of 12.3 and a price shift of +41.6%. Given that China accounted for 39.1% of import value, this shock had outsized macroeconomic relevance. This aligns with the global surge in plastics and energy prices following the post-COVID recovery and the onset of the Russia–Ukraine conflict. Two additional shocks of lesser magnitude were detected: a −13.0% price drop in EU exports to Türkiye in 2021 and an +11.8% price increase in EU exports to Switzerland in 2022.

Trade volatility was highest with the United States and Russia

The coefficient of variation — a measure of trade-flow instability — reveals that the most volatile import relationships were with the United States (CV 0.568), the United Kingdom (0.450), and Russia (0.683 for imports). On the export side, the most volatile partner was Morocco (CV 0.325), followed by Mexico (0.294). These figures suggest that while the EU's overall trade in plastic closures has grown smoothly, individual bilateral corridors have been subject to significant year-to-year fluctuations, often linked to policy changes (e.g., Brexit, sanctions) or macroeconomic cycles.

Conclusion

Over the 2015–2025 period, the EU's trade in plastic closures (CN 39235090) displayed robust growth, with trade values rising far more steeply than physical volumes — a pattern consistent with broader inflationary trends in plastics and energy inputs. The EU sustained its net-exporter status and a stable trade surplus of approximately €200–300 million. However, the period was far from static. China's emergence as the overwhelmingly dominant supplier, the contraction of UK-sourced imports post-Brexit, the collapse of exports to Russia following sanctions, and the deepening of supply-chain ties with Türkiye and Serbia all point to a significant geographical reconfiguration of trade. Import concentration has risen, and while the EU's structural vulnerability remains modest, the growing reliance on a single supplier warrants strategic attention. Looking forward, the balance between cost-efficiency from diversified global sourcing and the need for supply-chain resilience will be a central consideration for policymakers and industry stakeholders in this sector.
