Market evolution: Flexible metal hose (CN 830710) — 2015–2025

Introduction

Flexible tubing of iron or steel (CN 830710) is a versatile industrial product used across sectors such as oil & gas, construction, automotive, and general engineering. Over the decade spanning 2015 to 2025, the European Union's trade in this product has undergone a pronounced transformation. EU exports grew by 76 % in value, while imports more than doubled (+106 %). Despite the faster growth rate of imports, the EU has remained a decisive net exporter throughout, with its trade surplus widening from EUR 357 million to EUR 591 million. Domestic production volumes more than tripled over the same period, signalling a sector that has scaled up substantially while simultaneously deepening its orientation towards global markets.

This report examines the main dynamics behind these headline figures. It is organised around three core findings: the EU's strengthening net-exporter position; the geographic reorientation and rising volatility of its trade partnerships; and the structural shift towards greater trade openness driven by rapidly expanding production.

1. Robust Export Expansion and a Widening Trade Surplus

The EU's flexible metal hose sector has consistently posted a positive trade balance with the rest of the world, and that surplus has widened considerably over the decade. This section examines the evolution of exports, imports, and the resulting balance, and considers the role of unit-value dynamics.

Exports grew strongly in both volume and value

Between 2015 and 2025, EU exports of CN 830710 rose from EUR 484 million to EUR 851 million (+76.1 %), while export volumes grew from 28,058 t to 41,612 t (+48.3 %). Because value expanded faster than volume, export unit values also increased by 18.7 %, from EUR 17,233/t to EUR 20,454/t. However, the trajectory was not linear: export unit values fell to a trough of EUR 11,066/t at some point during the period—likely in 2020, reflecting the COVID-19 demand shock and shifts in product mix—before recovering sharply to their highest level in 2025.

Imports nearly doubled in value, driven by both volumes and rising prices

EU imports of CN 830710 climbed from EUR 127 million in 2015 to EUR 261 million in 2025, a rise of 105.7 %. Import volumes increased by 43.5 % (from 13,150 t to 18,875 t), while import unit values jumped by 43.3 % (from EUR 9,643/t to EUR 13,816/t). Unlike exports, import prices hit their peak of EUR 14,253/t near the end of the period, suggesting that post-pandemic supply-chain reconfiguration and rising input costs pushed up import prices throughout 2021–2025.

The price differential confirms the EU's upstream positioning

A persistent feature of EU trade in this product is that export unit values substantially exceed import unit values. In 2015, the EU exported at EUR 17,233/t while importing at EUR 9,643/t—a ratio of roughly 1.8:1. By 2025 the ratio narrowed slightly to approximately 1.5:1 (EUR 20,454/t vs. EUR 13,816/t), as import prices rose faster than export prices. This pattern is consistent with the EU specialising in higher-value-added flexible tubing—likely incorporating advanced fittings, corrosion-resistant alloys, or precision engineering—while importing more commodity-grade products.

The trade surplus widened substantially, reaching EUR 591 million

The EU's trade surplus with non-EU countries grew from EUR 357 million in 2015 to EUR 591 million in 2025 (+65.5 %). Although the surplus narrowed to a trough of EUR 150 million at some point during the period—likely in 2020, when the pandemic depressed export demand more sharply than imports—it subsequently rebounded to its highest-ever level. This resilience underscores the structural nature of the EU's competitive advantage in this product category.

2. Geographic Diversification Alongside Emerging Partner Volatility

Behind the aggregate trade figures, the geographic composition of EU trade in CN 830710 has shifted markedly. Both import and export markets have become less concentrated, but the growing importance of politically or economically volatile partners introduces new risk dimensions.

Import sources diversified, with China, Türkiye, and the US in the lead

The top seven import partners by value in 2025 were the United States (EUR 48 m), Türkiye (EUR 57 m), China (EUR 56 m), the United Kingdom (EUR 18 m), India (EUR 17 m), Serbia (EUR 11 m), and Korea (EUR 6 m). All major suppliers except Korea expanded their shipments to the EU over the period:

The most dramatic shift has been Serbia's emergence as a significant supplier, growing from a negligible EUR 0.2 million to EUR 10.7 million (+6,359 %). This is consistent with broader trends in Western Balkans integration into EU industrial supply chains, particularly as Serbia has attracted metalworking FDI. India also more than doubled its share, likely reflecting the country's growing steel tube manufacturing capacity.

Import concentration as measured by the Hirschman-Herfindahl Index (HHI) declined from 1,671 to 1,508 in value terms, moving from the "moderately concentrated" range (HHI 1,000–1,800) towards the unconcentrated threshold. This diversification reduces single-source dependency but also reflects the growing number of mid-sized suppliers to the EU market.

Export destinations underwent a dramatic African reorientation

The export-side geography reveals even more dramatic shifts:

The most striking feature is the near-total collapse of exports to Ghana—from EUR 74.5 million to less than EUR 0.3 million (−99.6 %)—and the explosive growth of exports to Nigeria (from EUR 1.0 million to EUR 41.6 million, +4,209 %) and Angola (from EUR 40.4 million to EUR 154.8 million, +283 %). Angola became the EU's single largest export destination for CN 830710 by 2025, overtaking the United Kingdom. These swings are characteristic of oil-sector-driven demand: flexible metal hoses are used extensively in offshore and onshore petroleum infrastructure, and African oil-producing nations' import patterns closely track investment cycles in upstream energy projects.

Export HHI in value terms fell from 920 to 809—an unconcentrated profile that became even more dispersed. The UK's share of EU exports diminished (−9.4 % in absolute terms), while the loss of Ghana was more than offset by gains in Angola and Nigeria.

Volatility is concentrated in energy-linked African and emerging-market partners

The coefficient of variation (CV) of trade values reveals starkly different risk profiles across partners. Stable suppliers such as China (CV 0.13) and the United Kingdom (CV 0.13) contrast with highly volatile import sources like Serbia (CV 0.78), Brazil (CV 0.98), and Tunisia (CV 1.05). On the export side, Switzerland (CV 0.11) and the United States (CV 0.28) were the most stable destinations, while shipments to Nigeria (CV 1.48), Ghana (CSV 1.46), Angola (CV 1.35), and Australia (CV 1.63) displayed extreme year-to-year swings.

Three extreme price-shock events were detected:

The Trinidad and Tobago event in 2018 likely reflects a single large-scale project delivery (e.g., LNG infrastructure), while the 2022 Ghana and Nigeria shocks coincide with the post-pandemic energy investment boom and the surge in oil prices following the Russia–Ukraine conflict. These events, though isolated, illustrate how concentrated exposure to energy-sector-driven economies can generate outsized price volatility in EU export flows.

EU member states show distinct specialisation profiles

The specialisation analysis (RSCA) for 2025 highlights significant intra-EU variation:

France dominates EU exports with EUR 417 million in 2025—roughly half of the EU total—followed by Germany (EUR 153 m) and a surging Denmark (EUR 146 m). On the import side, Germany (EUR 58 m), France (EUR 47 m), and Italy (EUR 25 m) are the largest buyers of extra-EU flexible tubing.

3. Scaling Production and Accelerating Global Market Integration

Beyond trade flows alone, the EU's flexible metal hose sector has undergone a structural transformation in how deeply it is embedded in global markets. Production volumes surged, export propensity nearly doubled, and the sector's net-export position deepened markedly.

Domestic production scaled dramatically

EU production of CN 830710 in volume terms grew from 98.7 million kg in 2015 to 312.4 million kg in 2025 (+216 %), while production value rose more modestly from EUR 824 million to EUR 1,301 million (+57.9 %). The divergence between volume growth (+216 %) and value growth (+58 %) implies that the implicit production unit value fell substantially—from approximately EUR 8.3/kg to EUR 4.2/kg. This could reflect a compositional shift towards higher-volume, lower-value standardised tubing products, improved production efficiencies, or increased competition driving down prices at the manufacturing level. It is worth noting that production reached a peak of 360 million kg and EUR 1,642 million in value at some point during the period before declining to the 2025 levels, suggesting some cyclical softening.

Export propensity surged past 50 %, signalling a fundamentally export-oriented sector

The export propensity—defined as exports relative to production—more than doubled from 22.7 % to 54.1 % over the decade. In other words, more than half of EU production is now destined for non-EU markets, up from less than a quarter in 2015. This is the single most significant structural shift revealed by the data: the sector has transitioned from being primarily oriented towards intra-EU demand to being fundamentally dependent on export markets.

Similarly, trade intensity—the sum of exports and imports as a share of production—rose from 27.4 % to 61.9 % (+126 %), confirming that the sector is now deeply integrated into global value chains.

The EU's net-exporter position strengthened considerably

Net import reliance was negative throughout the entire period—confirming the EU's status as a net exporter—and deepened from −19.5 % in 2015 to −50.8 % in 2025. At its most extreme point, net import reliance reached −106.5 %, indicating a year in which exports substantially exceeded the entire domestic production base (implying drawdowns from inventories or intra-EU re-routing). The stable negative trend confirms that the growth in exports has consistently outpaced the growth in imports, anchoring the EU's position as a structural net supplier of flexible metal hoses to the world.

Conclusion

The EU trade in flexible metal hoses (CN 830710) has experienced a decade of robust growth and structural transformation between 2015 and 2025. Three overarching conclusions emerge from the data:

First, the EU has consolidated its position as a major net exporter. Despite imports more than doubling in value, exports grew even more strongly, and the trade surplus widened to EUR 591 million. The EU's export price premium over imports confirms its specialisation in higher-value-added products, a competitive advantage that proved resilient through the COVID-19 pandemic and subsequent supply-chain disruptions.

Second, the geographic landscape of EU trade has been reshaped. Import sources diversified moderately (HHI declining from 1,671 to 1,508), with Serbia and India gaining ground. On the export side, a dramatic reorientation took place: Ghana's near-total disappearance as a destination was more than compensated by the explosive growth of shipments to Angola and Nigeria, reflecting the oil-and-gas-driven nature of much demand for this product. This shift, however, introduces heightened volatility, as several African partners display extreme year-to-year variability and were subject to notable price shocks in 2018 and 2022.

Third, the sector has undergone a fundamental reorientation towards global markets. Production volumes more than tripled, export propensity surpassed 50 %, and trade intensity reached 62 %. The EU flexible metal hose industry is no longer primarily serving domestic demand—it has become an export-oriented manufacturing sector deeply integrated into global energy and industrial supply chains.

Looking ahead, key risks include the concentration of high-growth export markets in politically and economically volatile oil-producing nations, the rising cost of imports as global steel prices remain elevated, and the potential for trade policy shifts (e.g., carbon border adjustments or anti-dumping measures) to alter competitive dynamics. Nevertheless, the sector's demonstrated ability to scale production, diversify markets, and sustain a strong net-export position provides a solid foundation for continued growth.
