Market evolution: Plastic bottle caps (CN 39235010) — 2015–2025

Introduction

This report analyses the trade dynamics of the European Union in plastic caps and capsules for bottles (customs code 39235010) over the period 2015–2025. The EU is a major global player in this market, characterised by large export volumes and significant imports. The period was marked by major shifts in trade flows, rising unit values, and changing partnership structures, all occurring within a context of growing domestic production and evolving market concentration.

1. Shifting trade balances and rising unit values mark a decade of transformation

The EU's trade in plastic bottle caps has undergone significant structural changes between 2015 and 2025. The bloc has maintained a consistent positive trade balance, but its magnitude has eroded substantially, primarily driven by divergent trends in export and import volumes alongside a generalised escalation in prices.

• The EU's trade balance in this product fell by 42.5% over the period, from a surplus of €276.8 million in 2015 to €159.2 million in 2025.
• This contraction is the result of two concurrent trends: a decline in export volumes and a strong increase in import values.

Export volumes contracted while import values surged

The EU's export performance weakened in volume terms but was partially offset by higher prices. Conversely, imports became significantly more expensive, suggesting a shift in the cost structure or sourcing.

• EU export quantity decreased by 28.0%, from 78,529 tonnes to 56,538 tonnes, while the export value only fell by 7.2%.
• The average export price rose by 28.8%, from €5,409 to €6,968 per tonne, indicating a move towards higher-value-added products or general inflation.
• In parallel, EU import value surged by 58.6% to reach €234.9 million in 2025, despite a 25.9% drop in imported quantity (to 24,329 tonnes). This was due to a massive 114.2% increase in the average import price, which reached €9,653 per tonne.

Price divergence reflects changed sourcing and product mixes

The stark difference in the price evolution between exports and imports suggests a structural change. By 2025, the average unit price of imports was approximately 38% higher than that of exports, a reversal from the start of the period. This could reflect the EU increasingly importing more specialised or higher-cost caps, or a significant change in the supplier mix.

2. The partnership map is being redrawn, with China's role expanding and intra-EU specialisation increasing

The composition of the EU's top trading partners for plastic bottle caps evolved considerably, with traditional partners experiencing relative decline and newer, sometimes more volatile, suppliers gaining prominence. Internally, EU Member States showed diverging patterns of specialisation.

China and Turkey became leading import sources, while UK export share fell

The concentration of import sources and export destinations shifted, as highlighted by the Herfindahl-Hirschman Index (HHI) which decreased for both flows, indicating a slight diversification of partners.

• For imports, the United Kingdom remained the largest supplier in value terms, but its share grew only modestly (+28.7%). In contrast, imports from China surged by 158.8%, making it the second-largest source. Imports from Türkiye (+68.1%) and Ukraine (+656.6%) also grew rapidly.
• For exports, the United Kingdom, while still the top destination, saw its value decline by 30.7%. Exports to the Russian Federation collapsed by 56.7%, likely reflecting geopolitical tensions. Notable growth was seen in exports to Israel (+67.6%) and Morocco (+44.4%).

Large EU producers dominate intra-EU flows, with niche specialisations emerging

Analysis of intra-EU specialisation reveals a core of industrial producers and several smaller Member States with high Revealed Symmetric Comparative Advantage (RSCA) in this product category.

• Large-scale producers like Germany and Italy are the top EU exporters. Germany's exports grew marginally (+1.7%), while Italy's declined (-20.8%).
• Niche specialists: Smaller economies like Luxembourg, Slovenia, Malta, Lithuania, and Hungary exhibit very high specialisation (RSCA > 0.37), indicating their production is more focused on this sector than the EU average.
• Major importers: Countries like the Netherlands, Ireland, and Italy have negative RSCA scores and are significant importers, reflecting strong domestic demand that is partly met from other EU producers or external sources.

3. Production growth and external supply shocks highlight strategic dependencies

Despite the trade balance shrinking, the EU's domestic production of plastic caps and capsules grew robustly over the period. However, the market remains exposed to volatility from specific external suppliers and was subject to isolated price shocks, underscoring vulnerabilities in the supply chain.

EU production volumes and values increased significantly

Data from Eurostat production statistics shows a healthy expansion of domestic manufacturing capacity.

• Production quantity grew by 14.4%, from 1.92 billion kg to 2.20 billion kg.
• Production value increased even faster, by 39.6% to €7.67 billion, indicating significant price inflation or a move into higher-value product segments within the EU.

Supply chains show concentrated volatility and specific price shocks

Analysis of the coefficient of variation (CV) reveals that some of the EU's key trading relationships are quite volatile.

• Import flows from Switzerland (CV 0.66) and Mexico (CV 1.18) were the most volatile, indicating unstable supply patterns. China, a major supplier, also showed notable volatility (CV 0.31).
• The most significant supply shocks detected were price spikes in exports to third countries in 2022, notably to Israel and Australia. While these countries are not major partners by value, such shocks can indicate disruptions in specific market segments or supply chains.

Conclusion

The 2015–2025 period was one of structural adjustment for the EU's plastic bottle caps market. The bloc's net exporter position weakened, not due to a collapse in exports, but because of soaring import costs and prices. The partner landscape shifted, with China emerging as a more critical supplier and the UK's dominance in exports waning. Domestically, production increased, suggesting investment, but this growth occurred alongside rising import penetration in value terms, pointing to potential challenges in cost competitiveness or product specialization. The high volatility in certain import streams and specific external price shocks highlight ongoing supply chain dependencies. Future market stability will depend on the EU's ability to leverage its growing production base while managing the cost and security of its external sourcing.
