Market evolution: Vacuum flasks and parts (CN 9617) — 2015–2025

Introduction

This report examines the trade dynamics of vacuum flasks and other vacuum vessels (excluding glass inners), classified under Combined Nomenclature code 9617, within the European Union's external trade over the period 2015–2025. The data reveals a market undergoing significant structural transformation: while the EU has managed to roughly double the value of its exports over the decade, imports have grown at a far more dramatic pace—increasing more than fourfold in value and over threefold in volume. This divergence has resulted in a rapidly widening trade deficit and a sharp rise in the EU's import dependency. At the same time, the EU's own production of vacuum flasks has contracted, and the geographic composition of both import sources and export destinations has shifted considerably. The following sections analyse these trends in detail, examining the asymmetry between import and export growth, the reconfiguration of trading partnerships, and the structural vulnerabilities that have emerged as a consequence.

A Widening Trade Gap: Import Growth Far Outpaces Export Recovery

The most striking feature of the EU's trade in vacuum flasks between 2015 and 2025 is the pronounced asymmetry between import and export trajectories. While both flows grew in value, imports surged by 319.6%—from EUR 125.1 million to EUR 525.1 million—compared to a 93.8% rise in exports—from EUR 79.6 million to EUR 154.3 million (General Overview). The trade deficit consequently ballooned from EUR 45.5 million in 2015 to EUR 370.9 million in 2025, an increase of over 700%.

Import volumes tripled while export volumes declined

The divergence is even more pronounced when volume is considered. EU imports of vacuum flasks grew from 16,123 tonnes in 2015 to 54,162 tonnes in 2025—a 235.9% increase. Over the same period, export volumes actually contracted by 11.6%, falling from 7,970 tonnes to 7,049 tonnes. This means that the near-doubling of export value was achieved not by shipping more goods, but by exporting higher-value products at substantially higher unit prices.

Unit price dynamics reveal a quality and value divergence

The price per tonne tell two very different stories on each side of the trade ledger:

Export prices more than doubled, suggesting the EU increasingly specialises in premium or niche vacuum flask products. Meanwhile, import prices rose only modestly, consistent with the continued dominance of mass-market, competitively priced goods—principally from China. The widening price gap between exports and imports indicates that the EU's role in this market is increasingly that of a high-value, low-volume exporter and a high-volume, moderate-value importer.

The trade deficit accelerated after 2020

While the deficit widened throughout the period, the acceleration appears most pronounced in the latter half of the decade. By 2025, the EU's net import reliance stood at 92.3%, up from 64.8% in 2015—a 42.5 percentage-point increase. This metric indicates that the vast majority of vacuum flasks consumed in the EU are now sourced from outside the bloc.

Shifting Geographies: China's Dominance on the Import Side and Diversification on the Export Side

The geographic composition of EU trade in vacuum flasks underwent substantial restructuring over 2015–2025. On the import side, China consolidated its already dominant position, while on the export side, the EU's customer base shifted away from traditional Middle Eastern markets toward European neighbours and emerging destinations.

China accounts for the overwhelming majority of import growth

China was by far the largest source of EU vacuum flask imports throughout the period, and its share of the import surge is dominant:

China's imports grew from EUR 114.0 million to EUR 490.7 million, representing over 90% of total EU import value by 2025. This dominance is reflected in the import concentration index (Herfindahl-Hirschman Index for imports by value), which remained elevated and even increased slightly from 8,306 to 8,906 (+7.2%), indicating persistently high supplier concentration.

Export destinations shifted from the Gulf to Türkiye and European neighbours

The export side presents a markedly different picture. The EU's traditional largest export market, Saudi Arabia, saw a dramatic collapse—from EUR 42.7 million in 2015 to just EUR 7.3 million in 2025 (−82.8%). Meanwhile, several new or previously minor destinations experienced explosive growth:

Türkiye emerged as the single largest destination for EU vacuum flask exports by 2025, absorbing EUR 52.0 million—up from just EUR 1.4 million in 2015. This 37-fold increase is remarkable and may reflect re-export dynamics, the growth of Turkish consumer markets, or supply chain reconfiguration. The United Kingdom also grew significantly as an export destination, likely partly a consequence of post-Brexit trade flows being captured in extra-EU statistics.

Export concentration fell sharply as markets diversified

Consistent with the shift away from a single dominant buyer (Saudi Arabia), the export concentration index (HHI by value) declined by 44.4%, from 3,066 to 1,704. This indicates that EU exports are now distributed across a broader set of partners, reducing dependency on any single market—a positive development from a diversification standpoint.

Declining Domestic Production and Rising Structural Vulnerability

Underlying the trade dynamics is a contraction in EU domestic production of vacuum flasks, which has contributed to the growing import dependency and raised questions about the bloc's industrial resilience in this product category.

EU production volumes and values declined over the period

Available production data shows a clear downward trend:

Production quantity fell by 16.9% and production value by 26.5%, indicating that EU manufacturers are producing fewer units at lower average values. This decline stands in stark contrast to the 235.9% growth in import volumes, suggesting that domestic production is being progressively displaced by foreign—principally Chinese—suppliers.

Poland and the Netherlands have emerged as the most specialised EU producers

The specialisation analysis for 2025 reveals that EU production and export of vacuum flasks is concentrated in a small number of member states:

The Netherlands stands out as accounting for 28.4% of EU production value and 14.5% of exports, while Poland contributes 15.0% of production and 6.6% of exports. Several larger member states—including Austria (RSCA: −0.68), Ireland (−0.94), and Luxembourg (−0.95)—show very low specialisation, indicating minimal involvement in this product category.

The Netherlands' export surge reshaped EU export geography

Among EU member states, the Netherlands experienced the most dramatic export growth, rising from EUR 4.9 million in 2015 to EUR 70.1 million in 2025 (+1,325.7%). Poland's exports grew even more rapidly in relative terms (+2,226.3%, from EUR 0.6 million to EUR 12.9 million). In contrast, Germany—historically the EU's largest exporter of vacuum flasks—saw its exports decline from EUR 57.7 million to EUR 31.7 million (−45.1%), though it remains a significant player.

The Netherlands also saw a massive increase in imports (from EUR 16.4 million to EUR 148.2 million, +801.1%), suggesting its role may partly involve re-export and distribution activities rather than purely domestic consumption.

Price volatility and supply shocks remain concentrated in specific corridors

The volatility analysis highlights several supply chains with elevated price instability. On the import side, Viet Nam (coefficient of variation: 2.06) and Thailand (1.72) showed the highest volatility, though both are small-volume suppliers. Among major partners, the United Kingdom (0.60) and Hong Kong (0.87) exhibited notable import price variability. On the export side, Türkiye (1.25), Saudi Arabia (1.04), and South Africa (1.21) were the most volatile destinations. Detected supply shock events include a significant price shock in EU exports to Kuwait in 2017 and to China in 2020, though neither appears to have materially altered the overall trade trajectory.

Conclusion

The EU's trade in vacuum flasks and parts over 2015–2025 tells a story of deepening import dependency, geographic reconfiguration, and industrial retreat. Import volumes tripled and import values quadrupled, driven overwhelmingly by Chinese supply, while domestic production contracted by 17–27% depending on the measure. The EU has managed to sustain export value growth—indeed, to nearly double it—but this has been achieved through higher unit prices on declining volumes, and by pivoting toward new markets, most notably Türkiye, the United Kingdom, and Switzerland, while losing the Saudi Arabian market that once dominated.

The structural implications are clear: the EU's net import reliance of 92.3% in 2025 leaves the bloc highly exposed to supply disruptions, exchange rate fluctuations, or trade policy changes affecting its principal supplier. At the same time, the concentration of import sourcing in China (HHI near 8,906) contrasts with a more diversified export base (HHI of 1,704), meaning that import-side risk is substantially higher than export-side risk. The EU's niche in this market appears to be shifting toward premium, high-value-added products—a defensible position, but one that coexists with an increasingly hollowed-out volume production base.
