Market evolution: Copper plates and sheets (CN 7409) — 2015–2025

Introduction

This report analyses the evolution of European Union trade in copper plates, sheets, and strip (Combined Nomenclature code 7409) between 2015 and 2025. The period is characterised by a fundamental shift in the EU's trade position, moving from a consistent trade surplus to a significant deficit. This transformation is driven by a structural surge in imports, which has outpaced export growth and reshaped the market's dynamics in terms of partners, production, and strategic vulnerability. The analysis is based on the comprehensive trade dashboard data provided.

1. From Surplus to Deficit: The Structural Rise of EU Imports

The period 2015-2025 witnessed a dramatic inversion of the EU's trade balance for CN 7409, primarily fuelled by an unprecedented expansion in import volumes and values.

Import volumes and values grew far more rapidly than exports

While EU export values grew by 15.1% over the period, import values surged by 238.8%. In volume terms, the divergence was even starker: export quantities fell by 32.6% (from 177,075 tonnes to 119,320 tonnes), whereas import quantities increased by 138.0% (from 25,722 tonnes to 61,206 tonnes). This data on trade flows indicates that the EU market's demand growth has been increasingly met by suppliers outside the bloc.

The trade surplus eroded significantly

The EU's trade balance, measured in value, declined from a surplus of €1.00 billion in 2015 to €0.72 billion in 2025—a contraction of 27.7%. The net import reliance metric confirms this shift, showing a decrease in the negative value (indicating a surplus) from -34.2% to -20.6%, meaning the EU's export surplus relative to its market has diminished.

Price increases amplified the value shift

The entire period saw substantial unit price inflation. Export prices rose by 70.8% (to €11,498 per tonne), while import prices increased by 42.4% (to €10,601 per tonne). This price effect, driven by global copper cost increases and supply chain pressures, magnified the monetary impact of the volume trends, particularly inflating the value of imports.

2. Shifting Trade Partners and Concentration Dynamics

The geography of EU trade for CN 7409 underwent significant reorganisation, with imports becoming both more diversified in source and more concentrated around a few key suppliers, while export destinations remained relatively stable.

Key new import partners emerged with explosive growth

The most dramatic changes occurred among import partners. Traditional suppliers like the United Kingdom and the United States showed modest changes, but new or previously minor partners grew exponentially:

The partner breakdown reveals that by 2025, these four countries alone accounted for over €453 million in imports, representing a major structural shift in the EU's supply chain for semi-finished copper products.

Export markets remained dominated by established economies

The list of top EU export destinations for CN 7409 remained largely unchanged, led by the United States, Switzerland, the United Kingdom, and China. The export partner data shows that while values fluctuated, the core customer base did not experience the radical transformation seen on the import side.

Trade concentration trends differed for imports and exports

The Herfindahl-Hirschman Index (HHI), a measure of market concentration, tells an interesting story. For imports, the HHI decreased by 14.7% to 1,498, indicating a diversification of suppliers (away from a single dominant source). For exports, the HHI increased by 26.6% to 1,550, suggesting a slight concentration of export sales among fewer foreign buyers. This data on concentration implies the EU has broadened its import sources but is focusing its export efforts.

3. Domestic Production Decline and Increased Strategic Dependence

Underlying the trade shifts was a significant contraction in EU domestic production of these copper products, which heightened the bloc's reliance on external sources and created new vulnerabilities.

EU production volumes halved over the decade

Available production data shows a stark decline. Production quantities fell from 1,055,497 tonnes in 2015 to 560,000 tonnes in 2025, a drop of 46.9%. Production value also decreased by 12.6%, though less severely, due to the aforementioned price inflation. This reduction in the domestic industrial base directly explains the need for increased imports.

The EU's trade intensity and export propensity evolved

The EU's trade intensity (trade as a share of production) rose from 35.4% to 43.6%, confirming that the economy became more integrated with external markets for this product. Concurrently, export propensity (exports as a share of production) also increased, from 31.5% to 34.1%. This indicates that even as production shrank, the EU redirected a larger portion of its diminished output to export markets, partly in response to high global demand and prices. The vulnerability metrics highlight this increased market openness.

New import relationships exhibit high volatility

The volatility analysis of trade flows reveals that the new, fast-growing import partnerships are also the most volatile. For instance, trade with Bosnia and Herzegovina and China showed very high coefficients of variation (1.65 and 1.12, respectively) over the period, as seen in the volatility data. This suggests these supply lines, while growing, may be more susceptible to disruptions compared to the more stable relationships with established partners like the United States or Switzerland.

Conclusion

The EU market for copper plates and sheets (CN 7409) between 2015 and 2025 underwent a profound transformation. The era of a large, stable trade surplus gave way to a new reality defined by a shrinking surplus, a steep decline in domestic production, and a massive increase in imports. This import surge was not monolithic; it featured the explosive rise of new suppliers from the Western Balkans and China, altering the EU's supply chain geography. While export destinations remained constant, the EU's industrial capacity in this sector diminished, leading to higher trade intensity and a greater strategic reliance on foreign production. These trends, marked by price inflation and new supply volatility, have reshaped the market's risk profile and underline the shifting competitive landscape of the European copper semi-finished goods industry.
