Market evolution: Gas cylinders (CN 7311) — 2015–2025

Introduction

This report analyzes the evolution of the European Union's external trade in gas cylinders (CN 7311) over the 2015–2025 period. The data reveals a fundamental shift in the EU's trade position, moving from a strong net exporter to a more balanced but increasingly import-dependent market. Key dynamics include a surge in imports, particularly from new suppliers, a decline in export volumes despite stable values, and a significant reorientation of trade flows away from Russia following geopolitical events. The analysis is based exclusively on the provided statistical data.

The Erosion of the EU's Trade Surplus and Shifting Partnerships

The EU's trade in gas cylinders underwent a major structural shift between 2015 and 2025, characterized by a sharp increase in imports and a stagnation in export value, severely eroding the historical trade surplus.

Imports grew exponentially while export volumes contracted

The value of EU imports in this product category more than doubled, rising from €125.4 million in 2015 to €305.5 million in 2025, a 143.6% increase. Over the same period, import quantities grew by 134.8%, from 49,401 tonnes to 115,997 tonnes. In stark contrast, while export values remained relatively stable (decreasing only 0.7% to €461.9 million), export volumes plummeted by 27.6%, from 120,921 tonnes to 87,540 tonnes. This divergence indicates a significant rise in the average export price (up 36.9% to €5,267 per tonne) and suggests a potential shift in the EU's export profile towards higher-value or specialized products (General Overview).

The trade balance deteriorated, reducing the EU's net exporter position

Consequently, the EU's trade balance for gas cylinders fell from a surplus of €339.9 million in 2015 to €156.5 million in 2025, a decline of 54.0%. The net import reliance measure, while still negative (indicating a surplus), improved from -14.3% to -5.1%, confirming the erosion of the EU's net exporting status (Net Import Reliance).

Import sources diversified away from traditional partners towards China and Türkiye

The growth in imports was driven by a dramatic rise in shipments from China and Türkiye. Import values from China grew by 280.7% to €121.6 million, while imports from Türkiye surged by 283.6% to €99.0 million. Both countries became dominant suppliers, significantly increasing their share. In contrast, imports from other top partners like the UK, USA, and Switzerland saw more moderate growth. This shift led to a substantial increase in import concentration, as measured by the Herfindahl-Hirschman Index (HHI), which rose by 82.6% to a value of 2,817, indicating a higher dependency on a few key suppliers (Top Partners and Concentration).

Domestic Production Under Pressure with Emerging Specialization

While EU production data reveals a decline in volume, it shows resilience in value, suggesting adaptation within the bloc's manufacturing base. Concurrently, export specialization became more pronounced in specific member states.

EU production volume decreased sharply while production value increased

According to PRODCOM data, EU production of gas cylinders (metal containers for compressed or liquefied gas) fell by 24.2% in quantity, from 498,451 thousand kg in 2015 to 378,000 thousand kg in 2025. However, the production value grew by 49.3% to €1.63 billion over the same period. This combination points to a significant increase in the average unit value of production, likely due to inflationary pressures, a move towards more sophisticated products, or a contraction in the production of lower-value, high-volume standard cylinders (Production Volumes).

Export specialization concentrated in Central and Southern European economies

Analysis of 2025 data reveals a clear pattern of export specialization. The most specialized exporters, measured by Revealed Symmetric Comparative Advantage (RSCA), were Estonia, Czechia, Portugal, and Italy. Czechia and Italy were also the largest exporters by absolute value, accounting for 19.96% and 16.97% of EU production value, respectively. Conversely, countries like Malta, Ireland, and Sweden showed strong import reliance with near-zero or negative RSCA, highlighting the uneven distribution of production capabilities across the EU (Specialisation).

Increased Market Integration and Geopolitical Volatility

The period saw the EU's gas cylinder trade become more integrated with the global market, as reflected in higher trade intensity. This integration also exposed the market to significant volatility and disruptions, most notably from sanctions-related supply shocks.

Trade intensity and export propensity rose substantially

The EU's trade intensity for this product—measuring the total trade (exports + imports) relative to domestic production—increased from 29.1% in 2015 to 50.1% in 2025, a 72.6% rise. Similarly, the export propensity (exports as a share of production) grew from 22.2% to 35.1%. These metrics indicate that the EU market for gas cylinders became significantly more open and globally integrated over the decade, with production increasingly oriented towards both serving internal demand and competing on export markets (Trade Intensity and Export Propensity).

The most dramatic shock was the collapse of EU exports to Russia

The volatility analysis highlights the extreme instability of trade with certain partners. The single most significant trade shock was the near-total collapse of EU exports to the Russian Federation. Export values fell by 98.0%, from €24.7 million in 2015 to just €482,631 in 2025, with the sharpest decline occurring around 2022. This high volatility (coefficient of variation of 0.74) is directly attributable to the sanctions regime implemented in the wake of geopolitical conflicts. Other notable, though less severe, export price shocks were detected for Bosnia and Herzegovina (2021) and the Republic of Korea (2023) (Supply Shocks).

Conclusion

Over the 2015–2025 period, the EU's market for gas cylinders (CN 7311) transformed from one of strong net self-sufficiency to a more balanced but vulnerable position. The key trends were the explosive growth of imports, dominated by China and Türkiye, and the stagnation of export volumes, leading to a halved trade surplus. Domestically, production volumes contracted but values rose, suggesting adaptation, while export specialization became geographically concentrated within the EU. The market became substantially more globally integrated, as shown by increased trade intensity, but also more exposed to external shocks, most dramatically illustrated by the sanctions-driven collapse of exports to Russia. Overall, the decade ended with the EU more reliant on international supply chains for this product category and facing a more competitive and volatile global market environment.
