Market evolution: Electroplated steel wire coils (CN 72173049) — 2015–2025

Introduction

This report examines the evolution of EU trade in electroplated steel wire coils classified under CN 72173049 over the period 2015–2025. The product covers wire of iron or non-alloy steel, in coils, containing less than 0.25% carbon, plated or coated with base metals (excluding zinc, copper, bars and rods). It corresponds to PRODCOM code 24.34.11.30, used in applications ranging from fasteners and automotive components to industrial wire products.

Over the decade under review, the EU market for this product underwent a significant transformation. A trade surplus at the start of the period gave way to a structural deficit by its end, driven by rising import volumes and shifting supply origins. At the same time, export markets concentrated geographically, domestic production volumes declined but their value increased, and price shocks tested supply-chain resilience. The following three sections unpack these dynamics in detail.

I. The EU's Slide from Trade Surplus to Structural Deficit

The most striking macro-level development over 2015–2025 is the reversal of the EU's net trade position in electroplated steel wire coils. What began as a modest trade surplus in 2015 ended as a persistent deficit, reflecting both diverging trends in export and import volumes and a widening price gap between the two flows.

Export volumes contracted while import volumes expanded

Between the first and last years of the data window, EU exports of CN 72173049 fell from 2,914 tonnes to 2,214 tonnes (−24.0%), while their value edged down 12.4% from €5.84 million to €5.12 million. Over the same span, imports rose from 3,588 tonnes to 4,267 tonnes (+18.9%), with their value climbing 35.2% from €4.41 million to €5.96 million. The result: the EU swung from a positive trade balance of approximately €1.43 million in 2015 to a deficit of roughly −€0.84 million by 2025, a reversal of nearly €2.3 million.

Unit values diverged: the EU sells at a premium but buys in greater volume

A revealing feature of the decade is the persistent and widening price differential between EU exports and imports. In 2015, the average export price stood at €2,003 per tonne, already a 63% premium over the import price of €1,228 per tonne. By 2025, this premium widened further: export prices reached €2,310/t (+15.3%) while import prices settled at €1,397/t (+13.7%). This suggests that EU producers increasingly focused on higher-value, specialty segments of the market, while imports filled the volume-demand at lower price points — a classic pattern of vertical specialisation in steel wire products.

Domestic production volumes fell but their value rose

EU production data confirms this structural shift. Output in volume terms declined 23.2% — from 3.85 billion kg in the first period to 2.96 billion kg in the last — yet production value increased 38.6%, rising from approximately €2.02 billion to €2.80 billion. This implies a substantial increase in the average unit value of EU-manufactured product, consistent with a move up the quality ladder and away from commodity-grade wire.

Net import reliance turned positive, confirming structural vulnerability

The net import reliance ratio — defined as imports minus exports, divided by production — shifted from −0.21% in 2015 to +2.18% in 2025, a change of over 1,150%. While the absolute level remains modest, the sign reversal indicates that the EU is now a net importer of this product. The ratio peaked at 5.74% in an intermediate year, underscoring that the deficit, though narrowing slightly at the end, has become a structural feature of the market.

II. A Reconfiguration of Trade Partners: China's Rise, Korea's Decline, and Regional Diversification

Behind the aggregate trade numbers lies a profound reshuffling of the EU's trade geography. The import side saw the emergence of China and Ukraine as dominant suppliers at the expense of South Korea, while the export side became increasingly concentrated on North American markets and saw the near-disappearance of several once-significant Asian destinations.

China became the EU's primary import source, replacing South Korea

In 2015, South Korea was the EU's largest supplier of CN 72173049, with €2.86 million in imports — nearly four times China's €721K. By 2025, the positions had reversed decisively: China supplied €2.71 million (+276.3%) while South Korea fell to €1.21 million (−57.6%). China thus captured approximately 45% of EU imports by value in 2025, compared to just 16% a decade earlier.

Ukraine emerged as a major supplier, likely reflecting pre-war and post-disruption trade patterns

The most dramatic growth on the import side belongs to Ukraine, whose exports to the EU surged from €169K to €1.16 million (+590.9%). This placed Ukraine as the third-largest import source by 2025. The timing is noteworthy: Ukraine's steel sector suffered severe disruption following the 2022 invasion, yet the 2025 figures show a strong recovery or re-orientation of trade flows toward the EU — potentially reflecting EU trade-facilitation measures, nearshoring trends, or redirection of exports formerly destined for other markets.

Import concentration decreased as supply sources diversified

Despite China's rise, the overall concentration of imports (measured by the Herfindahl-Hirschman Index on value) actually fell, from 4,536 to 2,902 (−36.0%). This apparent paradox — a dominant supplier gaining share while overall concentration declines — is explained by the erosion of South Korea's formerly overwhelming market power and the entry of new suppliers such as Ukraine, Türkiye, and Viet Nam. The import market became less of a two-player game (Korea + others) and more of a multi-source landscape, albeit with China as the new leader.

EU exports became more geographically concentrated, centred on North America

On the export side, the picture is one of rising concentration. The export HHI nearly doubled from 1,264 to 2,493 (+97.2%). The United States (€1.74M, +52.5%) and Mexico (€1.72M, +57.1%) together absorbed approximately 68% of EU export value by 2025, up from 38% in 2015.

Several Asian export destinations collapsed, reshaping the EU's outward trade profile

The near-total disappearance of Malaysian demand (from €1.11 million to €3.5K, −99.7%) is the most dramatic single shift among export partners. Together with the decline in Swiss demand (−24.9%) and the stagnation of UAE flows, this left the EU's export base heavily reliant on North America. Meanwhile, Taiwan emerged as a small but fast-growing niche buyer (+37,434%, from €132 to €49,597), though its absolute scale remains modest.

III. Internal EU Dynamics: German Dominance and the Concentration of Export Capacity

Within the EU, the trade in CN 72173049 was shaped by the industrial geography of steel wire production. Germany emerged as the bloc's undisputed export hub, while import demand shifted eastward — notably toward Romania, Slovakia, and Finland — reflecting evolving manufacturing footprints and supply-chain linkages across the Union.

Germany consolidated its position as the EU's export powerhouse

Germany accounted for €4.08 million of the EU's €5.12 million in exports by 2025 — roughly 80% of the total. Its specialisation indices confirm this dominance: an RCA of 2.54 and an RSCA of 0.43, both the highest among EU member states. Italy (RCA 2.12, RSCA 0.36) and Poland (RCA 1.51, RSCA 0.20) are the only other members with revealed comparative advantage, but their export volumes shrank dramatically: Italy fell 81.5% (from €1.96M to €364K) and Poland fell 84.1% (from €181K to €29K).

This consolidation of exports in Germany — amid declining output from Italy and Belgium — drove the increase in export concentration noted in the previous section and suggests that German producers possess cost or quality advantages that have allowed them to retain external market access while competitors retreated.

Import demand within the EU shifted eastward

The geography of EU import demand also evolved substantially. Germany remained the largest single importer (€1.47M, +34.6%), but Romania surged from €36K to €2.04 million (+5,641%), and Slovakia leapt from €9.5K to €626K (+6,492%). Finland's imports also nearly tripled (+147.9%). Meanwhile, traditional importers such as Spain (−68.7%) and France (−45.5%) saw steep declines.

The eastern shift — particularly Romania's emergence as the second-largest EU importer — may reflect the relocation of downstream manufacturing (e.g., automotive, construction hardware) to Central and Eastern Europe, where lower labour costs attract wire-consuming industries that source their inputs from non-EU suppliers.

Price shocks in 2022 underscored the market's sensitivity to supply disruptions

The volatility analysis reveals several notable shock events concentrated around 2022. The most significant was a price shock in EU exports to India in 2022, with an abnormality score of 62.6 and a unit-value shift of +201.9%, though India represented only 2.3% of export value. On the import side, Chinese unit values jumped 36.7% in the same year (abnormality 20.5), affecting 40.1% of import value — by far the largest shock in absolute commercial terms. An earlier price shock from South Korea in 2018 (+58.6%, affecting 25.8% of import value) foreshadowed the vulnerability of concentrated supply. These events coincided with the global steel price surge of 2021–2022, driven by post-pandemic demand recovery, energy cost inflation, and supply-chain disruptions, and they hit the EU's import bill disproportionately given the growing share of Chinese supply.

Conclusion

The decade 2015–2025 saw the EU market for electroplated steel wire coils (CN 72173049) undergo three interconnected transformations. First, the bloc moved from a net exporter to a net importer, as export volumes shrank and import volumes grew — a shift reinforced by a persistent price premium that confined EU producers to higher-value segments. Second, the geography of trade was reshaped: China replaced South Korea as the dominant import supplier, Ukraine emerged as a major new source, and EU exports became increasingly concentrated on North American markets. Third, within the EU, German producers consolidated their export leadership while import demand migrated eastward toward Romania, Slovakia, and Finland — consistent with the broader eastward relocation of manufacturing activity.

These trends carry policy implications. The EU's growing net import reliance, combined with rising import concentration on China and the demonstrated susceptibility of import prices to supply shocks, points to a need for supply-diversification strategies. At the same time, the strength of German export specialisation and the shift toward higher production values suggest that EU competitiveness in this product class is not vanishing — it is narrowing in scope and moving upmarket. The sustainability of this model will depend on the EU's ability to maintain cost and quality advantages in premium segments while securing affordable input supplies for its downstream industries.
