Market evolution: Zinc plated high carbon steel wire (CN 72172090) — 2015–2025

Introduction

This report examines the trade dynamics of EU extra-EU trade in zinc-plated high-carbon steel wire (Combined Nomenclature code 72172090) over the period 2015–2025. This product — iron or non-alloy steel wire in coils containing at least 0.6% carbon by weight, plated or coated with zinc — serves a range of industrial applications including fencing, spring wire, and construction reinforcement. The EU has remained a net exporter of this product throughout the period, but the structure of both imports and exports has shifted markedly. Rising unit prices, a dramatic reorientation of partner countries, and increasing trade concentration are the defining trends of the decade. The overall trade dashboard provides the full picture from which the figures below are drawn.

1. A Decade of Divergence: Rising Prices, Declining Volumes

1.1. EU exports gained in value but shrank in volume

Between 2015 and 2025, EU extra-EU export value for CN 72172090 grew by 23.0%, rising from €54.0 million to €66.5 million. Over the same period, however, export volumes fell by 25.3%, from 43,391 tonnes to 32,408 tonnes. This divergence is explained by a sharp increase in the average export unit price, which climbed from €1,246/t to €2,051/t — a gain of 64.6%. This pattern is consistent with broader steel market dynamics: the post-COVID commodity price surge, elevated energy costs in Europe following 2022, and EU climate-related production cost increases all contributed to higher unit prices even as physical trade contracted.

1.2. Import volumes grew strongly while prices remained nearly flat

EU imports tell a contrasting story. Import value rose by 48.7%, from €28.3 million to €42.0 million, and import volumes increased by 47.7%, from 27,938 tonnes to 41,253 tonnes. Crucially, the import unit price barely moved — from €1,012/t to €1,019/t, a change of just 0.7%. This suggests that third-country suppliers, particularly from Asia and Türkiye, maintained competitive pricing despite global cost pressures, widening the price gap between EU-produced and imported wire. The trade overview shows these trends clearly.

1.3. The trade surplus narrowed but the EU remained a net exporter

The EU's trade surplus in this product declined modestly from €25.8 million in 2015 to €24.4 million in 2025 (−5.3%). In net-import-reliance terms, the EU remained a net exporter throughout the period, with the ratio fluctuating between −8.3% (2015, the strongest net-export position) and +0.8% (in one intermediate year). By 2025, the net import reliance stood at −6.3%, confirming continued but slightly reduced export orientation. The net import reliance view illustrates this trajectory.

1.4. EU domestic production volumes declined while values rose

Available production data shows that EU production of this wire fell from approximately 1,197 million kg (2015) to 980 million kg (2025), a decline of 18.1%. Yet production value rose by 51.2%, from €860 million to €1,300 million. This mirrors the export-side price effect: EU producers are producing less tonnage but at substantially higher unit values, reflecting both cost pass-through and possible product-mix shifts toward higher-value specifications.

2. A Dramatic Reorientation of Trading Partners

2.1. The United Kingdom's collapse as a bilateral partner

The single most striking geographic shift over the decade has been the near-disappearance of the United Kingdom from EU trade in this product. On the import side, UK-sourced imports to the EU fell from €5.1 million to just €377,000 — a decline of 92.5%. On the export side, EU exports to the UK dropped from €13.3 million to €5.2 million (−61.3%). In 2015, the UK was the EU's largest export destination and third-largest import source; by 2025 it had fallen to a minor role on both flows. This is almost certainly a direct consequence of Brexit, which introduced customs formalities, rules-of-origin requirements, and regulatory divergence that disrupted previously seamless intra-European steel supply chains.

2.2. Türkiye's surge as an import supplier

The most dramatic growth story on the import side has been Türkiye. EU imports of this product from Türkiye grew from €2.5 million in 2015 to €16.9 million in 2025 — an extraordinary increase of 565.5%. By 2025, Türkiye had overtaken China as the EU's second-largest import supplier (behind China at €17.2 million) and was closing the gap rapidly. This surge reflects Türkiye's expanding steel wire production capacity, its competitive cost base, and its customs union arrangement with the EU for industrial goods, which provides preferential access. The partner breakdown details these shifts.

2.3. China remained the largest import source

China consistently held the position of the EU's top import supplier throughout the period, with import value rising from €13.3 million to €17.2 million (+29.3%). Despite various EU trade defence measures on Chinese steel products, this segment continued to grow, suggesting either that CN 72172090 was not covered by the most restrictive measures or that Chinese pricing remained sufficiently competitive to absorb any duties.

2.4. Russia's decline and Ukraine's resilience

EU imports from Russia fell from €2.9 million to €1.2 million (−59.6%), a decline that accelerated after 2022 in line with EU sanctions imposed following Russia's invasion of Ukraine. Meanwhile, Ukraine — itself a significant steel producer — saw its exports to the EU grow from €2.0 million to €3.4 million (+70.1%), even amid wartime disruption. This likely reflects both the EU's liberalisation of trade measures with Ukraine and the redirection of Ukrainian steel exports away from traditional markets.

2.5. Export markets consolidated around EFTA and the United States

On the export side, Switzerland became the EU's largest extra-EU export market, with value nearly doubling from €11.7 million to €22.3 million (+89.7%). Norway also grew strongly, from €4.7 million to €13.9 million (+199.4%). The United States doubled from €4.9 million to €9.9 million (+101.6%). In contrast, Morocco virtually disappeared as an export destination (from €4.7 million to €69,000, −98.5%). This reorientation toward wealthy, high-standards markets (EFTA, North America) and away from North Africa is consistent with the EU's shift toward higher-value, higher-priced product segments.

2.6. EU Member States experienced divergent intra-bloc repositioning

Among EU Member States, the reporter-country view reveals stark contrasts:

Slovakia has emerged as the EU's dominant exporter of this wire, accounting for over half of EU extra-EU export value in 2025. Its strong specialisation (RSCA of 0.87, RCA of 14.5 in 2025) reflects the presence of major wire-drawing capacity. Meanwhile, traditional Western European exporters like Belgium and France have sharply reduced their extra-EU shipments, potentially shifting focus to intra-EU trade or exiting lower-margin product segments. On the import side, Spain's import bill grew by 252%, suggesting growing domestic demand or a repositioning as a distribution hub for third-country wire entering the EU market.

3. Rising Concentration and Emerging Vulnerabilities

3.1. Import sourcing became more concentrated

The Herfindahl-Hirschman Index (HHI) for EU imports by value rose from 2,874 to 3,377 (+17.5%). While these levels indicate a moderately concentrated market (not yet highly concentrated by standard thresholds of 2,500 for moderate and approaching higher thresholds), the upward trend is notable. The combined growth of China and Türkiye — now accounting for the vast majority of import value — means the EU's import base for this product is increasingly dependent on just two suppliers. The loss of the UK as a diversified source has further narrowed the import portfolio.

3.2. Export markets also became more concentrated

Export concentration rose as well, with the HHI increasing from 1,369 to 1,896 (+38.4%). The growing weight of Switzerland and the decline of diversified small-destination exports (Morocco, others) contributed to this. While the export HHI remains below the moderate-concentration threshold, the faster rate of increase (38.4% versus 17.5% for imports) signals a narrowing of the EU's export base. This makes the EU's export revenue in this segment more sensitive to demand shifts in a handful of key markets.

3.3. Trade intensity and export propensity both increased

The EU's trade intensity (total extra-EU trade as a share of production) rose from 21.7% to 29.5% (+35.6%), and export propensity (extra-EU exports as a share of production) increased from 15.6% to 19.7% (+26.9%). Both metrics indicate that the EU's wire industry has become more exposed to international markets over the decade. While this can reflect competitiveness, it also implies greater vulnerability to external shocks — particularly given the simultaneous rise in partner concentration.

3.4. Price shocks were detected in peripheral export markets

The volatility analysis identified several notable price shock events in EU exports. The most extreme was a price spike in exports to Morocco in 2020, with an abnormality score of 1,197.5 and a shift of +1,059.3% — likely reflecting a collapse in volume and a residual high-value transaction rather than a genuine market trend. More meaningfully, exports to Norway showed a significant price shock in 2022 (abnormality 94.3, shift +61.7%), coinciding with the global steel price spike driven by the energy crisis and post-pandemic supply constraints. Chile also exhibited a price shock in 2022 (+135.2%). These events underscore the sensitivity of the EU's export pricing to global commodity cycles.

3.5. Import-side volatility varied widely by partner

Among import suppliers, volatility — measured by the coefficient of variation of annual import values — was highest for India (1.30), the United Arab Emirates (1.10), and Mexico (0.92). These are intermittent or niche suppliers whose trade flows are inherently unstable. By contrast, China (0.26) and Ukraine (0.36) showed relatively low volatility, suggesting more predictable supply relationships. Türkiye (0.58) occupied an intermediate position, consistent with its rapid but somewhat uneven growth trajectory.

Conclusion

Over the 2015–2025 period, the EU's trade in zinc-plated high-carbon steel wire has been shaped by three overarching forces: price inflation, partner reorientation, and concentration. EU producers have seen their unit prices rise by nearly 65% on export markets while physical trade volumes have contracted. The geographic landscape has been fundamentally redrawn — Brexit nearly eliminated the UK from bilateral trade, sanctions curtailed Russian supply, and Türkiye emerged as a fast-growing import competitor. Looking ahead, the increasing concentration of both import and export markets, combined with rising trade intensity, suggests that the EU's position in this product segment, while still that of a net exporter, is becoming more exposed to external price and supply risks. Policymakers and industry stakeholders should monitor the Türkiye import surge and the narrowing of the EU's export base as potential medium-term vulnerabilities.
