Market evolution: Copper wire (CN 7408) — 2015–2025

Introduction

This report examines the evolution of EU trade in copper wire under Combined Nomenclature heading 7408 over the period 2015–2025. The product covers refined copper wire (both above and below 6 mm cross-section) as well as wire of various copper alloys (brass, cupro-nickel, and others), excluding stranded wire, cables, insulated wire, and musical instrument strings. The EU has maintained a structurally large trade surplus in this product throughout the decade, but the underlying dynamics — rising prices, shifting trade partners, declining production volumes, and significant geopolitical shocks — reveal a market that has been profoundly reshaped.

1. A Market Dominated by Price Inflation Rather Than Volume Growth

Export values rose dramatically while volumes barely moved

Over the 2015–2025 period, EU extra-EU exports of copper wire grew 63.8 % in value, rising from €2.03 billion to €3.32 billion. However, export quantities actually declined by 3.9 %, from 368,402 t to 354,076 t. The implication is clear: virtually all of the nominal export growth was driven by rising unit prices, which climbed 70.4 % — from €5,505/t to €9,382/t.

Imports expanded far faster than exports in relative terms

EU imports of copper wire surged by 211.3 % in value (from €319 million to €993 million) and 105.7 % in volume (from 49,772 t to 102,401 t). Both the starting values and the ending values represent the minimum and maximum of the series, indicating that imports grew almost continuously. Import unit prices rose 51.3 %, from €6,406/t to €9,693/t — somewhat less than the export-side price increase, which partly reflects a different product mix (imports skew more toward refined copper wire ≤ 6 mm and brass wire, which carry different price profiles).

The trade surplus remained robust despite faster import growth

The EU ran a persistent and widening trade surplus throughout the period. It expanded from €1.71 billion in 2015 to €2.33 billion in 2025 (+36.3 %), reaching a trough of €1.20 billion in 2020 (during the COVID-19 demand shock) before recovering strongly. The net import reliance remained negative throughout (meaning the EU is a net exporter), deepening from −7.3 % to −21.4 %, as exports grew faster than domestic demand absorbed imports.

2. A Dramatic Reorientation of Trade Partners

Turkish imports replaced Russian supply after sanctions

The most consequential shift on the import side was the collapse of Russian supply and its replacement by Turkish and other origins. Russian imports peaked at €108.8 million in 2021 before falling to essentially zero by 2023 — a clear consequence of EU sanctions following the invasion of Ukraine. The data reveals a price shock in 2021 (abnormality score of 53.6, +52 % shift) followed by a complete supply cut-off in 2023 (−100 %).

Meanwhile, Türkiye stepped in as the dominant supplier, with imports surging from €170 million (2015) to €578 million (2025) — a 238.9 % increase. Other emerging suppliers include:

Egypt's growth was particularly volatile: an import supply shock in 2019 (−95.3 %, abnormality 2.7) was followed by a strong rebound, with volumes reaching €102 million by 2025. Vietnamese supply, negligible in 2015, has become a significant factor.

Morocco emerged as the EU's largest export destination

On the export side, Morocco displaced the United Kingdom as the leading destination. Moroccan-bound exports surged from €294 million to €1.04 billion (+255.1 %), reflecting the growth of Morocco's automotive and electronics manufacturing sectors, which consume large volumes of copper wire. The United Kingdom, the former top destination, saw its share decline from €445 million to €302 million (−32.0 %), likely reflecting post-Brexit trade friction and shifting supply chains.

The strong growth in exports to Western Balkan countries (Serbia, Bosnia and Herzegovina) reflects the integration of these economies into European industrial value chains, particularly in the automotive wiring and electrical equipment sectors.

Trade concentration increased modestly on both sides

The Herfindahl-Hirschman Index (HHI) for import concentration by value rose from 3,127 to 3,587 (+14.7 %), indicating moderately concentrated but rising supplier dependence — driven largely by the growing weight of Türkiye. Export concentration also increased from 1,013 to 1,358 (+34.1 %), though it remains lower in absolute terms, reflecting the EU's diversified customer base.

3. Domestic Production Declined but EU Member States Diverged Sharply

EU production volumes fell while values held steady

EU domestic production of copper wire declined by 26.1 % in volume — from 3.24 billion kg to 2.40 billion kg — yet production value barely changed, rising 2.2 % from €12.50 billion to €12.77 billion. The minimum volume (2.25 billion kg) was recorded in 2023, while the minimum value (€7.49 billion) was in 2020. This stark divergence underscores the role of copper price inflation: the value of output was sustained by rising raw material costs even as physical output contracted.

Germany dominates production and exports, but new entrants are gaining ground

The export specialisation analysis reveals that in 2025, Germany accounted for 37.0 % of EU production and 21.2 % of total exports, with a revealed comparative advantage (RCA) of 1.75. However, several smaller member states showed even stronger specialisation:

Among the top exporting member states, Germany led at €994 million (+81.6 %), followed by Belgium at €859 million (+62.9 %) and Spain at €705 million (+101.5 %). Bulgaria stood out on the import side: its imports exploded from €5.9 million to €226.2 million (+3,743 %), suggesting the development of significant downstream copper processing capacity, possibly linked to the relocation of wire-drawing and cable manufacturing operations.

Product sub-segments reveal a shift toward larger-gauge refined copper wire

Examining the sub-product breakdown, the dominant export product is refined copper wire above 6 mm (740811), which accounted for 318,330 t and €2.89 billion in 2025 — representing roughly 90 % of export volume. This segment's quantity grew modestly from 314,000 t in 2015, while its value surged by 75.4 % due to price increases. On the import side, refined copper wire ≤ 6 mm (740819) was the largest segment by volume (41,328 t, €425 m in 2025), followed by refined wire > 6 mm (740811, 44,825 t, €407 m). Notably, imports of 740811 grew from just 12,801 t in 2015 to 44,825 t in 2025 — a 250 % increase — suggesting growing demand for semi-finished copper rod/wire that is not fully met by EU production. Brass wire (740821) also featured prominently in imports, with volumes around 10,700 t in 2025.

Conclusion

The EU copper wire market over 2015–2025 was shaped by three overriding forces: commodity price inflation, geopolitical disruption, and supply-chain reorientation. Export values grew by nearly two-thirds, but this was almost entirely a price phenomenon — physical trade volumes were essentially flat. The most dramatic structural change was the re-routing of import supply away from Russia and towards Türkiye, Egypt, and Vietnam, a shift driven by sanctions and diversification imperatives. Meanwhile, EU production volumes declined by a quarter, even as production value held steady — a clear sign of cost-push inflation rather than output growth. The EU's trade surplus widened, and its net-exporter position strengthened, but rising import dependence on a smaller set of suppliers (higher import HHI) introduces new concentration risks. Morocco's emergence as the leading export destination, and the growth of Western Balkan markets, reflect the ongoing geographic reconfiguration of European manufacturing supply chains. Going forward, the interplay between copper price volatility, green-transition demand for electrical conductors, and geopolitical supply risks will continue to define this market.
