Market evolution: Refined copper wire (CN 740819) — 2015–2025

Introduction

The period between 2015 and 2025 witnessed a fundamental transformation in the EU's trade position for refined copper wire (CN 740819). Starting from a position of a modest net exporter in 2015, the European Union concluded the period as a significant net importer. This structural shift was driven by a sharp decline in domestic production and export capacity, contrasted with a dramatic surge in imports, particularly from Türkiye. The average price of this commodity rose substantially, reflecting broader global copper market trends, but this did not prevent a deterioration in the EU's trade balance. This report analyses the key dynamics behind this evolution, focusing on the decline in EU production, the geographical reorientation of imports, and changes within the product category itself.

The Erosion of EU Production and Export Capacity

The most significant structural change observed in the data is the collapse of the EU's domestic production and its subsequent impact on export volumes. Despite rising unit values, the EU's ability to serve both its internal market and export markets with this product was fundamentally weakened.

A Dramatic Contraction in Domestic Manufacturing

EU production of CN 740819 wire fell precipitously over the decade. Production volumes declined by 55.6%, from 710,229 tonnes in 2015 to 315,000 tonnes in 2025. The production value also fell by 41.2%, indicating that the decrease was not solely due to lower commodity prices. This reduction in output is the primary underlying cause for the shifts observed in trade flows.

Declining Export Volumes Despite Higher Values

The reduction in production directly constrained the EU's export capacity. While the total value of EU exports increased by 11.4% to €265 million in 2025, the physical volume exported plummeted by 37.3% to just 25,010 tonnes. This divergence is explained by a 77.8% surge in average export prices, which masked the severe decline in quantities.

A Redrawing of the EU's Export Map

The composition of the EU's export markets shifted considerably. The United Kingdom, while remaining the top destination, saw its share of EU exports fall significantly. Exports to the UK dropped from €67.4 million to €25.1 million (-62.7%). In contrast, exports to Switzerland increased by 112.1% to €55.8 million, becoming the second-largest market. Trade with nearby partners like Moldova collapsed by 99.9%, while exports to North African partners like Morocco (+203.5%) and Tunisia (+266.9%) grew substantially. The Herfindahl-Hirschman Index (HHI) for export concentration fell from 1,211 to 807, indicating that export markets became somewhat more diversified despite lower volumes.

The Import Surge and Rise of New Suppliers

With domestic production in decline, the EU increasingly turned to international suppliers to meet demand. This led to a massive increase in import values and volumes, fundamentally altering the EU's trade balance and supply chain dependencies.

From Net Exporter to Net Importer

The most striking headline figure is the complete reversal of the EU's net trade balance. In 2015, the EU had a positive trade balance of €82.5 million. By 2025, this had swung to a deficit of -€159.6 million. This was driven by a 173.2% increase in the total value of imports, which reached €424.7 million in 2025, while import volumes grew by 68.1% to 41,328 tonnes. The EU's net import reliance consequently shifted from -5.4% (a net exporter) to +7.0% (a net importer).

The Dominance of Türkiye and the Emergence of New Suppliers

The growth in imports was overwhelmingly sourced from a few key countries. Türkiye's role expanded dramatically. Imports from Türkiye surged by 165% from €133.3 million to €353.1 million, making it by far the largest supplier. This concentration is reflected in the import HHI, which, although declining slightly to 6,981, remains high. Beyond Türkiye, imports from Uzbekistan (+39,344%), Mexico (+125,868%), and Serbia (+400.2%) exploded from negligible bases, indicating the emergence of new supply chains.

Growing Trade Intensity and External Reliance

The EU's economy became more intertwined with global markets for this product. Trade intensity—the combined value of imports and exports relative to domestic production—more than doubled, rising from 16.6% to 38.9%. This highlights the increasing dependence of the EU's copper wire sector on international trade, both for sourcing inputs and for finding markets.

Shifts in Product Mix and Market Volatility

Underlying the aggregate trade figures were important shifts in the specific types of refined copper wire being traded and episodes of significant price volatility.

Divergence in Sub-Product Performance

CN 740819 is a heading that bundles two distinct sub-products: thicker wire (74081910, >0.5mm to ≤6mm) and very thin wire (74081990, ≤0.5mm). Their trajectories diverged.

• Imports: Both sub-categories saw growth, but the thicker wire (74081910) was the primary driver. Its import volume grew by 73.1%, while the very thin wire's volume grew by 63.6%. In value terms, the thicker wire category saw a slightly larger proportional increase.
• Exports: The decline in EU export volumes was almost entirely concentrated in the thinner wire segment (74081990). Exports of this product collapsed by 70.1% in volume. In contrast, exports of the thicker wire (74081910) fell more moderately (-29.5%). This suggests the EU's loss of competitiveness was most acute in the finer, possibly more technologically intensive, wire segment.

Price Volatility and Notable Supply Shocks

The period was marked by considerable price volatility. Several supply relationships showed high variability (coefficient of variation), such as exports to Moldova (CV: 0.88) and imports from the UK (CV: 0.92). The most significant shock event detected was a 66.4% price spike in EU exports to the United Kingdom in 2021, which was highly abnormal and coincided with post-Brexit trade adjustments. A similar, though less extreme, shock was observed in exports to Moldova in 2023.

Conclusion

The EU's market for refined copper wire (CN 740819) underwent a profound restructuring between 2015 and 2025. The core narrative is one of a domestic production collapse that dismantled the EU's net export position and forced a deep reliance on foreign suppliers, particularly Türkiye. This shift was reflected in a dramatic reversal of the trade balance and a doubling of the sector's trade intensity. While rising global copper prices boosted nominal trade values, they could not compensate for the severe erosion in the EU's physical export volumes, especially in the finer wire segment. The resulting market structure is one of higher import concentration and greater exposure to external supply dynamics, representing a significant change in the competitive landscape for this industrial product within the European Union.
