Market evolution: High-carbon steel wire (CN 72171090) — 2015–2025

Introduction

This report analyses the trade dynamics of the European Union in high-carbon steel wire (Customs code 72171090) over the period from 2015 to 2025. This product, a specialised wire used in applications such as springs and ropes, is a key component in various industrial sectors. The analysis covers trade volumes, values, prices, partner composition, and the EU's production and structural adaptations within this market. The data reveals a period characterised by significant volume contraction, substantial price inflation, and a notable reorientation of trade flows, influenced by geopolitical events and competitive pressures.

The Shifting Trade Balance: Volume Contraction and Price Inflation

The EU's trade in high-carbon steel wire has undergone a profound transformation over the decade, marked by a stark divergence between physical volumes and monetary values. While the Union maintained a consistent trade surplus throughout the period, its scale and composition changed dramatically.

A persistent but evolving trade surplus

The EU consistently maintained a positive trade balance, indicating it is a net exporter of this product. The net import reliance was negative in every year, starting at -8.3% in 2015 and ending at -6.3% in 2025. This surplus, however, narrowed in value terms, decreasing by 14.4% from €55.1 million in 2015 to €47.2 million in 2025.

Export volumes halved while prices surged

The most significant trend was the drastic decline in export volumes coupled with a sharp increase in unit values. EU export quantities fell by 44.9%, from 98,652 tonnes in 2015 to just 54,336 tonnes in 2025. Conversely, the average export price increased by 61.6%, from €1,230 per tonne to €1,988 per tonne. This suggests a strategic shift towards higher-value segments or the impact of sustained cost increases (e.g., energy, raw materials) passed on to international buyers.

Import trends mirror the volume-price disconnect

Imports followed a similar pattern but to a lesser extent. Import volumes decreased by 15.6%, from 65,227 tonnes to 55,020 tonnes. The import price rose by 8.9%, from €1,016 to €1,106 per tonne. This price difference between exports and imports widened considerably, indicating a possible increase in the premium for EU-origin wire or a shift in the quality mix of traded goods.

Geopolitical Reorientation of Trade Partners

The geographic landscape of EU trade in this product underwent substantial restructuring, with traditional partners losing ground to emerging suppliers and key export destinations displaying divergent trajectories.

The rise of Türkiye and the decline of South Korea as import sources

Among the top import partners, Türkiye solidified its position, with imports growing by 59.2% to become the largest supplier by 2025. In stark contrast, imports from South Korea collapsed by 56.8%, falling from the top spot to third. The most dramatic increases were seen from Ukraine (+1,140%) and Thailand (+622.6%), albeit from lower bases.

Divergent fortunes in EU export markets

The United Kingdom remained a major destination but saw a 34.4% decline in value. The most dynamic growth occurred in Brazil, where export value surged by 85.7% to €37.4 million, making it the top export market by 2025. Meanwhile, exports to Mexico dropped sharply (-67.1%). This reorientation points towards the importance of regional trade agreements and shifting demand patterns in Latin America.

Increased volatility in certain supplier relationships

The coefficient of variation analysis highlights which partnerships were most unstable. Imports from Thailand (CV: 0.75) and the Russian Federation (CV: 0.72) were highly volatile. On the export side, a notable price shock was detected in exports to Brazil in 2022, where prices jumped by 89.7%, likely linked to the global energy and commodities crisis of that period.

Internal EU Adaptation: Specialisation and Structural Shifts

Faced with changing trade flows, the EU's internal production landscape and the specialisation of its member states evolved, indicating an adaptation towards higher-value output and greater export concentration.

Production value grew despite falling output

A key structural shift is evident in EU production. Production quantity (in kg) fell by 18.1%, yet production value increased by 51.2%, from €860 million to €1.3 billion. This mirrors the export price trend and strongly suggests that EU producers have moved up the value chain, focusing on more sophisticated or processed high-carbon wire products.

Growing concentration in EU exports

The Herfindahl-Hirschman Index (HHI) for exports more than doubled, increasing from 785 to 1,592. This rise indicates that EU export flows became significantly more concentrated among a smaller number of destination countries, potentially increasing vulnerability to market-specific shocks.

Divergent specialisation within the EU

The analysis of Revealed Symmetric Comparative Advantage (RSCA) for 2025 shows clear internal specialisation. Slovakia, Portugal, Croatia, and Austria show high comparative advantage (RSCA > 0.58) and a notable share of their national production in this sector. Conversely, countries like Finland, Latvia, Denmark, Romania, and Slovenia exhibit very low or negative specialisation (RSCA < 0), indicating they are not competitive producers of this wire.

Conclusion

Over the 2015–2025 period, the EU market for high-carbon steel wire (CN 72171090) demonstrated remarkable resilience in value terms but underwent a fundamental structural transformation. The overarching trend was a decline in traded volumes alongside significant price inflation, which preserved the monetary value of the trade surplus and EU production despite lower physical output. Geopolitically, trade patterns were redrawn, with traditional partners like South Korea and the UK seeing reduced trade shares, while Türkiye and Brazil became significantly more important as a supplier and a customer, respectively. Internally, the EU industry appears to have adapted by specialising in higher-value production, as evidenced by rising production values and export prices, even as output volumes contracted. This suggests a strategic move towards niche, high-margin segments of the global steel wire market. The increased concentration of exports, however, may pose a strategic risk that warrants monitoring. Overall, the sector showcases a classic case of industrial adjustment in a mature, cost-sensitive industry facing global competition.
