Market evolution: Zinc plated carbon steel wire coils (CN 72172050) — 2015–2025

Introduction

This report examines the intra-EU production and extra-EU trade dynamics of CN 72172050 — wire of iron or non-alloy steel, in coils, containing 0.25 %–0.60 % carbon, zinc-plated or zinc-coated. This product, mapped to Prodcom code 24.34.11.50, sits at the intersection of the European steel wire industry and the construction/infrastructure supply chain. Over the 2015–2025 period, the EU has remained a consistent net exporter to non-EU partners, yet import volumes have grown faster than export volumes. Meanwhile, unit export prices have risen steeply, reflecting both a global commodity price cycle and a structural shift toward higher-value shipments. The period has also been punctuated by geopolitical shocks — Brexit, the COVID-19 pandemic, and EU sanctions on Russia — each of which left distinct fingerprints on partner flows. This report is structured around three principal findings.

1. A Persistent but Narrowing Trade Surplus Driven by Price Rather Than Volume

Export volumes declined while export values rose, signalling a unit-price effect

Between 2015 and 2025, extra-EU exports of CN 72172050 evolved as follows:

The EU exported less material in 2025 than in 2015, yet earned more revenue — a clear indication that higher unit prices, not volume growth, sustained the value increase. The export price peak of EUR 1,892/t was reached at some point during the period (likely 2022, coinciding with the post-COVID steel price spike), before moderating to EUR 1,563/t by 2025.

Import growth outpaced export growth on both value and volume

Imports followed a markedly different trajectory:

Import values rose more than three times faster than export values (+54.3 % vs. +21.8 %). Critically, imports also grew in volume (+37.2 %) whereas export volumes shrank (−7.7 %). The trade surplus, while still positive, narrowed from EUR 26.3 million at its peak to EUR 15.9 million by 2025. The net import reliance remained negative throughout (confirming net-exporter status), but moved from −5.1 % to −4.0 % — a 22.5 % reduction in the net-export margin.

The persistent price gap between exports and imports points to product differentiation

In every year, the EU's unit export price exceeded its unit import price — in 2025, the gap was EUR 1,563/t vs. EUR 1,051/t (a 49 % premium). This is consistent with the EU exporting higher-specification wire (tighter tolerances, certified coatings, niche alloys within the CN subheading) while importing more commoditised or standard-grade product, particularly from China and emerging suppliers such as the United Arab Emirates.

2. Geopolitical Shocks Restructured EU Trade Partners Between 2020 and 2023

Russia's collapse as an import and export partner is the most dramatic structural shift

The partner-level data reveals a sharp and sanctions-driven reorientation away from the Russian Federation:

EU imports of this wire from Russia peaked at EUR 993,346 and then collapsed to EUR 146,285 — a supply shock formally detected in 2023 with a −100 % shift and an abnormality score of 4.9. EU exports to Russia also declined, but more modestly (−16.8 %), likely because some pre-sanctions contracts were honoured and because certain steel products were not immediately embargoed. The residual export flow of EUR 774,795 in 2025 may reflect re-routing or residual permitted trade.

Ukraine and the UAE filled part of the supply vacuum

As Russian supply contracted, two new or expanded import sources emerged:

Ukraine's growth from EUR 321,340 to EUR 2,116,469 — making it the EU's second-largest import supplier by 2025 — is striking. This occurred despite the disruption caused by Russia's full-scale invasion in 2022, suggesting that Ukrainian wire producers redirected output toward the EU market as other export channels closed. The United Arab Emirates' emergence (from EUR 234,327 to EUR 833,533) also reflects growing trade via intermediary hubs; notably, this flow exhibited a price shock in 2020 with a 148 % price shift and an abnormality of 14.9, suggesting a possible surge in re-routed or non-standard supply at that time.

China remained the largest single import partner throughout

China held the top position among EU import sources in both 2015 (EUR 1,556,083) and 2025 (EUR 1,929,849), growing 24.0 % over the period. While less dramatic than Ukraine's rise, China's stable dominance underlines the structural competitiveness of Chinese wire producers, whose export price to the EU (EUR ~935/t in 2015) has consistently undercut the EU's own export price level.

Export destinations were more stable, but with notable price shocks to the UK

EU exports were heavily concentrated on three Western markets — Norway, the United Kingdom, and the United States:

Norway's share grew the most, possibly linked to energy-sector and maritime infrastructure demand. The UK export flow recorded a price shock in 2022 (abnormality 3.8, +61.9 % shift), consistent with the global steel price spike following the energy crisis and post-COVID demand surge. As the largest single export destination by value share (32.2 %), UK trade dynamics exert outsized influence on the aggregate EU export series.

3. Central European Producers Anchor EU Production While Market Concentration Tightens

EU production volumes were broadly stable, but production values nearly doubled

The EU production series shows a striking divergence between volume and value:

Output in tonnes was essentially flat — ranging from a trough of 465 million kg to a peak of 675 million kg — while production value rose by 93.8 %, implying that the EU average production price nearly doubled over the decade. This mirrors the global steel price cycle (the 2021–2022 spike and subsequent correction) and confirms that the rise in export unit prices was not merely a mix effect but reflected genuine input-cost and pricing escalation throughout the value chain.

Czechia and Slovakia dominate extra-EU exports with strong revealed comparative advantage

The specialisation analysis for 2025 identifies Central Europe as the clear production and export hub:

Czechia alone accounted for nearly half of all extra-EU export value in 2025, despite representing only 4.8 % of total EU production volume — a remarkable export intensity. Czechia's extra-EU exports grew from EUR 7.5 million (2015) to EUR 12.7 million (2025, +70.6 %), and it was the single largest exporting Member State by value throughout the period. Slovakia's exports surged from EUR 1.4 million to EUR 3.7 million (+154.3 %), though they had peaked at EUR 9.1 million in an intermediate year.

At the other end, Poland's extra-EU exports collapsed from EUR 1.4 million to just EUR 1,263 (−99.9 %), even as Poland became the EU's largest import market (EUR 1.8 million in 2025, up from EUR 612,000 in 2015). This suggests that Polish wire producers shifted focus to intra-EU trade or downstream integration, while Polish end-users increasingly sourced raw wire from outside the EU.

Trade concentration increased on both the import and export sides

The Herfindahl-Hirschman Index rose for both flows:

The increase in export concentration (HHI from 1,849 to 2,577, +39.3 %) reflects the growing dominance of Norway, the UK, and the US at the expense of smaller, more volatile markets such as Canada, Uruguay, and Chile. Import concentration also rose, partly because Ukraine's surge offset the diversification effect of new entrants such as the UAE. An HHI above 2,500 is generally considered to signal a moderately concentrated market, raising the question of whether EU buyers and sellers are becoming more exposed to single-partner risks.

Conclusion

The EU market for CN 72172050 — zinc-plated, medium-carbon steel wire coils — over 2015–2025 is characterised by three overarching dynamics. First, the EU has maintained its status as a net exporter throughout, but the surplus has narrowed as import volumes grew (+37 %) while export volumes contracted (−8 %); the surplus was sustained only by steep unit-price appreciation. Second, geopolitical disruption has materially restructured the partner landscape: Russian trade has nearly collapsed, Ukraine has emerged as a major import source, and China has remained the single largest supplier — while export destinations have been more stable but increasingly concentrated around Norway, the UK, and the US. Third, Central European producers — above all Czechia and Slovakia — have consolidated their role as the EU's export engine, while Polish and Scandinavian exporters have retreated from extra-EU markets. EU production volumes have been broadly flat, meaning the near-doubling of production value reflects price dynamics rather than output growth.

Looking ahead, the concentration of both import and export flows in a small number of partners (HHI now above 2,500 on both sides) warrants attention from a supply-chain resilience perspective. The EU's continued reliance on China and the rapid growth of Ukrainian and UAE supply raise questions about pricing sustainability and origin transparency. On the export side, the heavy dependence on three Western markets means that any demand softening in Norway, the UK, or the US would disproportionately affect the EU's zinc-plated wire trade balance.
