Introduction

This report analyses the evolution of EU trade in coiled high carbon steel wire plated with base metals (excluding zinc) (CN 72173090) from 2015 to 2025. The product is a specialized semi-finished good used in industrial applications such as springs, ropes, and reinforcement. The analysis is based on annual trade data between the EU and non-EU countries, covering value, volume, prices, partner dynamics, and structural indicators. The period saw significant shifts in global trade flows, influenced by economic cycles, policy measures, and supply chain reconfigurations. The product overview dashboard provides the complete dataset for reference.

1. Sustained Export Growth and an Improving Trade Balance

The EU's external trade in CN 72173090 is characterized by a strong performance in exports, which significantly outpaced import growth, leading to a marked improvement in the trade balance over the decade.

EU exports surged in both value and volume, narrowing the trade deficit

Between 2015 and 2025, the value of EU exports increased by 137.1%, from €23.7 million to €56.2 million, while exported quantities grew by 113.6%, from 17,547 tonnes to 37,485 tonnes. This robust expansion contrasts with a relatively stagnant import performance. The value of imports grew only 2.9% (from €72.1 million to €74.1 million), and imported volumes slightly decreased (-2.4%). Consequently, the EU's trade deficit improved dramatically, narrowing by 62.8% from a deficit of €48.4 million in 2015 to €18.0 million in 2025. The trade overview highlights this trend.

Import prices fluctuated more dramatically than export prices

While both export and import prices saw net increases, import prices exhibited greater volatility. The unit value of exports rose by 11.0%, peaking at €1,946/t in 2021 before settling at €1,498/t. Import prices increased by 5.4% on net but experienced a wider swing, dropping to a low of €1,020/t in 2016 and spiking to a high of €1,769/t in 2021, reflecting the impact of global commodity cycles and supply chain disruptions more acutely on incoming flows.

2. Consolidation of Import Sources and Geographic Specialization in Exports

The period witnessed a major consolidation of EU import sources, particularly the rise of China, alongside a geographic re-orientation of export destinations, with increasing specialization among EU member states.

China became the dominant supplier, increasing import concentration

China's share of EU imports grew massively, with its value increasing by 183.1% to reach €63.1 million in 2025, making it by far the largest single source. Meanwhile, traditional suppliers saw sharp declines: imports from South Korea fell by 95.7% and from Malaysia by 99.7%. This shift led to a dramatic increase in import concentration, as measured by the Herfindahl-Hirschman Index (HHI), which rose by 172% from 2,681 to 7,292. This indicates a significant reduction in supplier diversification and a heightened reliance on China. Concurrently, some newer suppliers like Vietnam (+3,704%) and Turkey (+396.5%) gained ground from a low base. The partner concentration dashboard details this transformation.

Export destinations shifted towards neighboring and emerging markets

EU exports became more diversified by partner, with the HHI for exports declining by 9.9%. The most striking shift was the rise of Turkey, which became the top destination with export value soaring by 2,204.6% to €16.4 million. Serbia (+989.8%) and Egypt (+390.9%) also emerged as key growth markets. In contrast, exports to the United States, the top partner in 2015, collapsed by 81.1%. This re-orientation suggests a focus on regional supply chains (Turkey, Serbia) and growing markets in the Middle East and Africa. The partner dashboard shows these evolving patterns.

Internal EU specialization increased, with Central Europe becoming a core export base

Within the EU, trade became more concentrated around specialized producers. Slovakia and Czechia emerged as the most specialized exporters (high Revealed Symmetric Comparative Advantage), leveraging their industrial base. This is reflected in their trade flows: Czechia saw a monumental 122,539% increase in export value, becoming a top EU exporter. Meanwhile, traditional industrial cores like Germany saw their export role diminish. The data from the specialisation dashboard points to a more geographically focused EU production network for this product.

3. Rising Trade Intensity Amid Concentration Risks and Volatility

Despite a stronger export performance, the market structure reveals growing vulnerabilities linked to import dependency and price volatility, even as the EU's overall integration into global trade for this product deepened.

The EU's trade intensity and export propensity grew, signaling deeper market integration

The EU became more involved in global trade for this product. The trade intensity (exports+imports as % of production) rose from 21.7% to 29.5%. More notably, the export propensity (exports as % of production) increased from 15.6% to 19.7%, indicating that a growing share of domestic production was being directed to foreign markets. The net import reliance remained negative (the EU was a net exporter), but its improvement (from -8.3% to -6.3%) aligns with the stronger export growth. These metrics are detailed in the vulnerability dashboard.

Import concentration created specific supply vulnerabilities

The soaring HHI for imports highlights a key risk: dependency on a single major supplier, China. This concentration increases exposure to potential trade disruptions, geopolitical tensions, or export restrictions. The import concentration and net import reliance dashboards quantify this structural shift.

The market experienced notable price shocks and volatility in export relationships

Trade was not smooth. Several extreme price volatility events were detected. The most severe was a 270.6% abnormal price shift in exports to Egypt in 2021. Exports to Mexico and the United Kingdom also saw significant price shocks in 2022. These shocks suggest episodic market tightness or specific contract anomalies. Furthermore, high coefficient of variation (CV) values for exports to the United States (1.41) and Mexico (1.55) point to a fundamentally volatile trade relationship with these partners. The volatility dashboard provides the detailed shock analysis.

EU production shifted towards higher value despite lower volume

EU domestic production (Prodcop 24.34.11.70) saw its quantity decline by 18.1% from 1.20 billion kg to 0.98 billion kg, yet its value increased by 51.2% from €860 million to €1.30 billion. This indicates a move up the value chain, with production potentially focusing on higher-quality or more processed variants of the wire, which commands better prices and supports the observed export growth. This evolution is shown in the production volumes data.

Conclusion

The EU market for plated high carbon steel wire (CN 72173090) between 2015 and 2025 was defined by a strong export performance that significantly reduced the trade deficit. This growth was supported by a reorientation towards dynamic regional partners like Turkey and Serbia, and increased internal specialization within the EU, particularly in Central Europe. However, this period also saw the consolidation of imports from China, creating a high degree of supplier concentration and associated vulnerability. While the EU integrated more deeply into global trade for this product, as shown by rising trade intensity, the market faced episodes of price volatility and structural risks. The concurrent shift in EU production towards higher-value output suggests an adaptive industry, but the reliance on a dominant import source remains a key factor shaping the market's future trajectory.
