Market evolution: Galvanised steel wire coils (CN 72172010) — 2015–2025

Introduction

This report examines the EU's external trade in galvanised steel wire coils (customs code 72172010) — a low-carbon, thin-gauge wire product used across construction, fencing, and industrial applications. Over the 2015–2025 period, the overall trade picture reveals a market undergoing a fundamental structural reorientation. The EU shifted from a modest net exporter to a net importer, while unit values climbed sharply on both sides of the trade ledger. Three dynamics stand out: a pronounced contraction of EU export capacity, a growing dependence on a single dominant supplier, and a price environment shaped by global steel market turbulence. Each is explored in the sections below.

1. From Net Exporter to Net Importer: A Structural Shift in the EU's Trade Position

EU exports contracted far more steeply than imports over the decade

The most striking feature of this period is the asymmetry between the evolution of exports and imports. According to the trade overview, EU exports fell by 47.9% in value (from €13.4 million to €7.0 million) and by 63.1% in volume (from 8,374 tonnes to 3,090 tonnes). Imports, by contrast, grew by 16.9% in value (from €10.0 million to €11.7 million), while their volume actually declined slightly by 8.1% (from 7,719 tonnes to 7,093 tonnes). The combined effect was a swing in the trade balance from a surplus of €3.4 million in 2015 to a deficit of €4.7 million by 2025.

The collapse in exports was driven by the loss of several major destinations

The decline in EU exports was not uniform across partners. Several formerly significant markets shrank or disappeared entirely. Exports to the United States fell by 91.1% (from €2.0 million to €181,000), while shipments to Russia collapsed by 99.4% (from €1.0 million to just €7,000). Exports to Norway declined by 42.5% and to Mexico by 45.5%. Only Morocco (+35.9%) showed a meaningful increase among the top destinations. This pattern suggests that EU producers lost competitiveness in distant and price-sensitive markets, while retaining or growing in geographically proximate ones.

EU net import reliance shifted from self-sufficiency to mild dependency

The net import reliance indicator confirms this structural turn. In 2015 the ratio stood at −0.2%, indicating that the EU was a marginal net exporter of this product. By 2025 it had risen to +2.2%, a swing of over 1,153 percentage points from its minimum value. While the absolute level remains modest, the direction of travel is unambiguous: the EU has become reliant on external suppliers to meet domestic demand for this wire product.

2. China's Dominance and the Concentration of EU Import Supply

China accounts for the vast majority of EU imports and its share has grown

Looking at the partner breakdown, China is by far the dominant supplier. In the last period, Chinese imports totalled €9.8 million out of a total of €11.7 million — representing roughly 83% of all non-EU imports by value. Over the decade, the value of Chinese imports rose by 13.7%, while the volume of total EU imports fell. This implies that China maintained or increased its shipments even as other suppliers retreated, and that the EU's growing import bill is overwhelmingly a China story.

Japan emerged as a notable secondary supplier from a negligible base

One interesting development is the rise of Japan as a source of imports. Starting from virtually zero (€1,625) in 2015, Japanese imports reached €1.4 million by 2025 — making it the second-largest supplier after China. This corresponds to a price shock event detected in the data, where Japanese export prices to the EU surged by 325.3% around 2022. The emergence of Japan may reflect EU buyers seeking alternatives to Chinese supply, possibly in the context of trade defence measures or supply-chain diversification strategies. However, Japan remains a distant second to China, accounting for roughly 12% of non-EU imports by value.

The import market remains highly concentrated despite modest diversification

The Herfindahl-Hirschman Index (HHI) for imports by value stood at 7,161 in the last period — well above the 2,500 threshold typically associated with a highly concentrated market. While this represents a modest decline from its 2015 level of 7,442 (−3.8%), the structural concentration on China has barely diminished. By contrast, the export-side HHI was only 615, reflecting a much more diversified set of destination markets. This asymmetry underscores a key vulnerability: the EU's import supply for this product is structurally dependent on a single country.

The United Kingdom's post-Brexit decline reshaped trade flows

The United Kingdom deserves special mention. As an import source, it fell by 93.2% (from €956,000 to €65,000), while as an export destination it declined by 35.8% (from €1.2 million to €800,000). The UK's transition from a significant bilateral partner to a marginal one reflects the trade friction introduced by Brexit, which altered the cost and regulatory calculus for this commodity across the Channel.

3. Rising Unit Values, Shifting Production Geography, and Price Volatility

Unit values rose sharply on both the import and export sides

A common thread across both trade flows is the significant increase in unit prices. Export unit values rose by 41.3% (from €1,602/tonne to €2,263/tonne), while import unit values increased by 27.2% (from €1,302/tonne to €1,656/tonne). The fact that export prices rose faster than import prices is partly explained by the changing composition of EU exports: as low-value, high-volume destinations (such as Russia and the US) disappeared, the remaining export basket skewed toward higher-value markets. The general overview shows that export prices peaked at €2,349/tonne and import prices at €2,071/tonne during the period, both exceeding their 2025 levels — indicating that the 2021–2022 global steel price surge had a lasting impact on the market.

EU production volumes declined but production value increased

Domestic EU production tells a complementary story. Output volumes fell by 23.2% (from 3.85 billion kg to 2.96 billion kg), but the value of production rose by 38.6% (from €2.02 billion to €2.80 billion). This divergence — less steel produced, but at a higher aggregate value — is consistent with the broader trend of rising steel prices over the period, likely driven by higher energy costs, raw material prices, and environmental compliance costs in the EU.

Production concentrated in a handful of specialised EU member states

The specialisation data for 2025 reveals that EU production is geographically concentrated. Germany accounts for 23.6% of total EU production by volume, followed by Slovakia (25.0% of product-specific output) and Spain (14.3%). At the other end, countries such as Greece, Latvia, and Croatia produce negligible quantities. This concentration means that disruptions in a small number of member states — whether from energy shocks, labour disputes, or regulatory changes — could have an outsized impact on EU supply.

Price shocks were detected in several bilateral trade relationships

The volatility analysis identified several notable price shocks. An India export shock in 2017 involved a 159.2% price shift; a China export shock in 2022 saw a 325.3% spike; and a United Arab Emirates event around 2020 showed a 234.6% jump. These anomalies likely reflect the turbulence in global steel markets during the 2021–2022 period, when pandemic-related supply disruptions, surging energy costs, and policy interventions (including EU safeguard measures) combined to create extreme price volatility. China's import flows showed the lowest volatility (coefficient of variation of 0.13), confirming its role as a steady — if dominant — supplier.

Conclusion

The EU market for galvanised steel wire coils (CN 72172010) underwent a significant transformation between 2015 and 2025. The bloc shifted from a net exporter to a net importer, with export volumes falling by over 60% while import values grew by nearly 17%. This shift was driven by the loss of key export markets — particularly the United States and Russia — and the resilience of Chinese supply, which now accounts for over 80% of non-EU imports by value. Prices rose substantially on both sides, reflecting broader global steel market dynamics and the EU's rising production costs. The market's structural concentration on China, combined with the geographic clustering of EU domestic production among a small number of member states, presents both efficiency gains and potential vulnerabilities. Looking ahead, the interplay between trade defence policy, energy costs, and supply-chain diversification efforts will likely shape the next phase of this market's evolution.
