Market evolution: Iron wire coils (CN 7217) — 2015–2025

Introduction

This report examines the trade performance of the European Union in Wire of iron or non-alloy steel, in coils (CN 7217) over the period 2015–2025. The product covers iron or non-alloy steel wire in coils — excluding bars and rods — and encompasses four sub-categories: uncoated wire (721710), zinc-coated wire (721720), wire coated with base metals other than zinc (721730), and wire with other coatings (721790). The sector is a foundational input for the construction, automotive, and manufacturing industries.

Over the decade, the EU's position in this market has undergone a structural transformation. What was once a comfortable trade surplus has eroded into a modest deficit. Import values have risen by 31.9% while export volumes have contracted by nearly a fifth. At the same time, the geopolitical landscape has reshaped trade flows dramatically: the war in Ukraine and sanctions on Russia and Belarus have disrupted long-standing supply chains, while Turkey and China have surged as import sources. This report analyses these dynamics across three main axes: aggregate trade performance, partner reconfiguration, and product-level and structural shifts.

1. From Surplus to Deficit: The Erosion of the EU's Net Trade Position

Aggregate trade flows diverge in volume and value

The EU's overall trade balance in CN 7217 shifted from a surplus of €102 million in 2015 to a deficit of €34 million in 2025 — a swing of −132.9%. This was not caused by a collapse in exports, which actually rose in value from €598 million to €621 million (+3.8%). Rather, it reflects a divergence between falling export volumes and rising import volumes. EU export quantities declined from 632,942 tonnes to 509,162 tonnes (−19.6%), while import quantities grew from 679,683 tonnes to 706,865 tonnes (+4.0%).

Price inflation masked the volume decline on the export side

A striking feature of this period is the sharp rise in unit prices. Export prices increased by 29.1% (from €945/t to €1,220/t), and import prices by 26.8% (from €730/t to €926/t). Both peaks occurred around 2022, when the global steel price surge — driven by post-pandemic demand recovery, energy cost shocks, and supply-chain disruptions — pushed the EU export price to €1,524/t and the import price to €1,382/t. The 2022 price spike is visible across all sub-products and helped inflate export revenues despite declining physical volumes.

Domestic production contracted in volume while rising in value

EU production of iron and steel wire in coils followed a similar pattern: output fell from 5.62 million tonnes in 2015 to 4.52 million tonnes in 2025 (−19.6%), while production value rose from €3.22 billion to €4.77 billion (+47.9%). The decline in volumes — combined with higher prices — suggests that EU producers may be focusing on higher-value segments or facing structural capacity constraints, while lower-cost imports increasingly serve the volume market.

The EU's net import reliance is trending upward

The net import reliance indicator, which measures the share of domestic consumption satisfied by net imports, moved from −2.77% in 2015 (a net exporter position) to −0.85% in 2025. In between, it briefly turned positive, peaking at 3.78% in 2022 — the year when the EU was a net importer of this product in value terms. Although the indicator reverted to slightly negative by 2025, the long-term trend points toward growing import dependence. Meanwhile, trade intensity rose from 16.6% to 23.8%, and export propensity from 10.3% to 13.9%, indicating that the EU's iron wire market is becoming more globally integrated, not less.

2. Geopolitical Earthquake: The Reconfiguration of Trade Partners

Sanctions and war rewired the EU's import supply base

The most dramatic change in the EU's CN 7217 trade over the decade concerns the origin of imports. The top import partners in 2015 included Russia (€49M), Belarus (€88M), and the United Kingdom (€42M) — all traditional, geographically proximate suppliers. By 2025, Russia had declined to €34M (−29.2%), Belarus to €68M (−22.9%), and the UK to just €9M (−79.6%). The collapse of Belarus as a supplier was particularly abrupt: the data detects a supply shock in 2023, when imports from Belarus fell by 100% from their peak — consistent with the tightening of EU sanctions against the Lukashenko regime.

Turkey and Ukraine emerged as major beneficiaries

The void left by sanctioned or receding suppliers was filled primarily by Türkiye and Ukraine. Turkish imports surged from €52 million to €163 million (+211.9%), making Türkiye the second-largest import source by 2025. Ukrainian imports grew even faster in percentage terms, from €29 million to €94 million (+229.8%). Both countries offer proximity, competitive labour costs, and — in the case of Ukraine — preferential trade arrangements with the EU. China, already the largest import source in 2015, nearly doubled its share to €263 million (+94.4%), reinforcing its dominant role.

Import concentration increased sharply

The Herfindahl-Hirschman Index (HHI) for import partners rose from 1,489 to 2,495 (+67.5%), moving from a moderately concentrated market into territory that trade economists typically regard as highly concentrated. This reflects the growing dominance of a small number of suppliers — particularly China, Türkiye, and Ukraine — at the expense of a more diversified import base. The HHI for import volumes reached 2,698 by 2025. This concentration creates vulnerability: any disruption to these few suppliers could have outsized effects on the EU market.

Export destinations shifted toward the near neighbourhood and emerging markets

On the export side, Switzerland remained the largest single destination, growing from €127 million to €186 million (+46.3%) and accounting for 30% of all EU exports in 2025. The United Kingdom, once the second-largest market at €103 million, fell to €67 million (−35.3%) — likely a consequence of post-Brexit trade frictions. Serbia (+298.8%, from €8M to €32M) and Türkiye (+90.9%, from €15M to €28M) stand out as rapidly growing destinations. The US market (+12.0%) and Brazil (+15.7%) grew more modestly but remained significant. The HHI for export concentration rose from 993 to 1,305 (+31.4%), a less dramatic but still notable increase.

Volatility varies widely across partners

The coefficient of variation (CV) of trade values reveals that some partnerships are far more stable than others. On the import side, China (CV 0.36), Ukraine (0.32), and Russia (0.37) show moderate volatility, while the UK (0.60) and Albania (1.12) are highly erratic. On the export side, the United States (0.11) and Switzerland (0.14) are the most stable destinations — reinforcing their role as anchor markets — while Algeria (0.87) and Morocco (0.42) are considerably more volatile. The price shock detected in exports to Brazil in 2022 (an abnormality score of 355.3 and a 54% price shift) stands out as the most extreme event in the data set, likely reflecting the global steel price frenzy of that year.

3. Product-Mix Shift: The Rise of Zinc-Coated Wire and a More Specialised EU

The import product mix pivoted decisively toward zinc-coated wire

The segment-level data reveals a striking structural shift in the EU's import basket. In 2015, uncoated wire (721710) dominated imports at 361,028 tonnes (53% of total import volume), while zinc-coated wire (721720) stood at 203,769 tonnes (30%). By 2025, the positions had nearly reversed: uncoated wire fell to 221,384 tonnes (31%), while zinc-coated wire surged to 382,144 tonnes (54%) — a near-doubling in volume. The other coated categories (721730 and 721790) remained relatively stable.

Export volumes declined across almost all sub-products

Unlike imports, where growth was concentrated in a single category, export volumes fell across the board. Uncoated wire (721710) — still the largest export segment — declined from 385,193 tonnes to 330,243 tonnes (−14.3%). Zinc-coated wire (721720) fell from 178,553 tonnes to 110,720 tonnes (−38.0%), meaning the EU not only failed to capture the growing global demand for galvanized wire but actually ceded ground. The other two sub-products (721730 and 721790) showed smaller movements.

Export prices consistently exceed import prices, but the gap varies by segment

Across all sub-products, EU export unit prices are higher than import prices — consistent with the EU producing and exporting higher-specification wire while importing more commoditised products. In 2025, the export–import price gap was widest for uncoated wire (€1,036/t exports vs. €943/t imports, a 10% premium) and narrowest for base metal coated wire (€1,533/t vs. €1,249/t, a 23% premium). Notably, the price gap narrowed in 2022 during the global price spike, suggesting that in periods of tight supply, lower-cost importers were able to capture higher unit values.

The EU's production specialisation is concentrated in a handful of Member States

The specialisation data for 2025 shows that export specialisation in CN 7217 is highly uneven across EU Member States. Luxembourg (RSCA 0.69, RCA 5.50) and Slovakia (RSCA 0.68, RCA 5.27) are the most specialised exporters, followed by Czechia (0.50), Italy (0.42), and Portugal (0.32). At the other end, Ireland, Malta, and Finland show negligible specialisation. Within the EU, Italy is by far the largest exporter in absolute value (€176M in 2025, up 100% from 2015), while Poland leads on the import side (€118M in 2025, up 82%). Romania's imports surged by 167% over the period, the fastest growth among major EU importers.

Conclusion

The EU's market for iron wire coils (CN 7217) underwent a significant transformation between 2015 and 2025. The bloc shifted from a net exporter position to near balance, with a trade surplus of €102 million in 2015 eroding to a deficit of €34 million by 2025. This was driven by a combination of declining export volumes (−19.6%) and rising import values (+31.9%), partially masked by a period of sharp global price inflation around 2021–2022.

The most consequential change, however, was geopolitical. The war in Ukraine and associated sanctions regime fundamentally restructured the EU's import supply base: Belarus experienced a total supply shock in 2023, and Russia's share declined steadily. Turkey and Ukraine stepped in to fill the gap, while China nearly doubled its already-dominant market share. Import concentration (HHI) rose by 67.5%, raising strategic vulnerability concerns.

At the product level, the EU's import appetite shifted decisively toward zinc-coated wire (721720), which nearly doubled in volume, while uncoated wire imports contracted. On the export side, volumes declined across nearly all sub-products, suggesting that EU producers may be losing competitiveness in lower-value segments. The structural data shows a market that is becoming more trade-intensive, more concentrated, and more dependent on a small number of non-EU suppliers — trends that merit close attention from policymakers concerned with industrial resilience and supply-chain security.
