Market evolution: Plastic caps and closures (CN 392350) — 2015–2025

Introduction

This report examines the evolution of European Union trade in plastic stoppers, lids, caps and other closures (Combined Nomenclature code 392350) over the 2015–2025 period. The product group encompasses bottle caps and capsules (39235010) alongside other plastic closures (39235090) and sits within the broader category of articles for the conveyance or packaging of goods (CN 3923). The EU remains a significant net exporter of these products, but the decade has seen notable shifts in trade values, partner relationships, and pricing dynamics — shaped by global supply chain disruptions, inflationary pressures, and geopolitical realignments.

The analysis draws on Eurostat trade data and covers imports, exports, partner concentration, and structural market indicators.

1. A Decade of Rising Values and Falling Volumes

1.1 EU exports grew in value but contracted in physical volume

The EU's export performance in plastic closures over the decade reveals a fundamental shift toward higher-value shipments. Export value rose from €1.07 billion in 2015 to €1.36 billion in 2025 (+27.5%), while export volumes actually declined from 190,376 tonnes to 183,026 tonnes (−3.9%). The average unit export price consequently climbed from €5,618 per tonne to €7,447 per tonne (+32.6%).

This divergence between value and volume suggests that European producers have moved upmarket — producing more specialised, higher-margin closures — or that input cost inflation (resin prices, energy, labour) has been passed through to export prices. Production data supports both interpretations: EU production quantity grew 14.4% (from 1.92 million tonnes to 2.20 million tonnes) while production value surged 39.6% (from €5.49 billion to €7.67 billion), indicating that unit values have risen across the board.

1.2 Imports expanded much faster, driven by price inflation

Imports tell a starker story. The EU's import bill for plastic closures grew 71.7% — from €576 million to €989 million — far outstripping the 5.8% rise in import volumes (from 112,804 tonnes to 119,354 tonnes). The average import price nearly doubled, rising 62.2% from €5,108 per tonne to €8,287 per tonne.

The import price increase exceeded the export price increase (62.2% vs. 32.6%), suggesting that the EU's external suppliers — particularly China and Türkiye — experienced even sharper cost escalation or shifted toward higher-value-added segments.

1.3 The trade surplus narrowed substantially

As a result of imports growing faster than exports, the EU's trade surplus shrank by 24.2% — from €493 million in 2015 to €374 million in 2025. The net import reliance ratio (which is negative for a net exporter) moved from −9.9% to −6.0%, reflecting a 39.5% decline in the EU's export advantage. Despite this erosion, the EU remained a consistent net exporter throughout the period.

2. Geopolitical Shifts in Partner Relationships

2.1 China became the EU's dominant import source

The most striking development in EU import relationships is China's meteoric rise. Chinese exports of plastic closures to the EU surged from €136 million in 2015 to €364 million in 2025 — a 167.6% increase that made China by far the largest source of EU imports, accounting for approximately 36% of the import value by 2025.

Türkiye also registered dramatic growth (+257.9%), reflecting its emergence as a cost-competitive supplier serving the EU customs union area. By contrast, the United Kingdom — now an external partner since Brexit — remained relatively flat at around €176 million, with only a marginal 1.5% increase.

2.2 Russia's collapse as an export destination reshaped EU export flows

On the export side, the near-halving of EU exports to Russia (−55.2%, from €66 million to €30 million) was the defining geopolitical disruption. The decline accelerated after 2022 following the imposition of EU sanctions related to the Russia–Ukraine conflict. This was offset by growth in other markets: the United States (+47.7%), Türkiye (+46.3%), Serbia (+76.7%), and Switzerland (+25.6%).

2.3 Import concentration tightened while export markets diversified

The Herfindahl-Hirschman Index (HHI) for imports rose from 1,900 to 2,049 (+7.8%), indicating increasing concentration — largely driven by China's growing dominance. Meanwhile, the HHI for exports declined from 831 to 734 (−11.6%), reflecting the diversification of EU export destinations away from Russia and toward a broader set of markets.

This divergence carries strategic implications: while the EU's export base has become more resilient through diversification, its import dependency has become more concentrated on a smaller number of suppliers — with China alone accounting for over a third of import value.

3. Price Shocks, Volatility, and Structural Shifts

3.1 A major price shock hit EU imports from China in 2022

The volatility analysis reveals three significant shock events over the period:

The China import price shock of 2022 — coinciding with post-COVID supply chain disruptions and energy cost spikes — was by far the most consequential given China's 36.4% share of EU import value. A 35.6% annual price jump on such a large volume amplified cost pressures throughout the European packaging supply chain.

3.2 China and Israel showed the highest trade volatility

Across the full period, the coefficient of variation (CV) in import values highlights significant variation among key partners:

Israel and the US exhibit the highest volatility, potentially reflecting more episodic or opportunistic trade patterns. The UK's relatively high CV (0.36) may partly reflect post-Brexit adjustment effects. On the export side, Russia displayed the highest volatility (CV 0.36), consistent with the sanctions-driven collapse in trade flows.

3.3 EU production capacity expanded, but export propensity declined

Despite robust production growth, the EU's export propensity — the share of production destined for non-EU markets — declined from 19.5% to 18.0% (−7.5%). This suggests that more of the additional output is being absorbed by the EU internal market rather than exported. Trade intensity (total external trade as a share of production) remained broadly stable at around 27%.

Within the EU, production is concentrated among a few large member states. Germany led exports at €379 million (2025), followed by France (€224 million) and Italy (€158 million). Notably, Italy's imports surged 154.3% (from €41 million to €104 million) while its exports slightly declined — potentially indicating a shift in Italy's role from net exporter toward a more balanced position. France maintained the highest revealed comparative advantage (RSCA of 0.37) among major producers, confirming its specialisation in this product category.

Conclusion

Over the 2015–2025 decade, EU trade in plastic caps and closures has been characterised by three overarching dynamics: rising unit values outpacing volume growth, a geopolitical reshuffling of trade partners, and growing import concentration on China.

The EU remains a net exporter of plastic closures, but its trade surplus has eroded as imports — particularly from China — have surged in both value and price. The loss of the Russian export market, while significant, has been offset by growth in North American, Turkish, and Balkan markets, resulting in a more diversified export base. Price shocks, especially the 2022 spike in Chinese import prices, exposed the risks of supplier concentration.

Looking ahead, the key vulnerabilities centre on the EU's increasing dependence on Chinese imports — a concentration risk that has intensified even as export markets have diversified. The decline in export propensity, despite rising production capacity, may warrant attention from policymakers seeking to maintain the EU's competitive position in global markets for packaging components.
