Market evolution: Stainless steel wire nickel chromium coils (CN 72230011) — 2015–2025

Introduction

This report analyses the EU's international trade in CN 72230011 — wire of stainless steel, in coils, containing by weight 28% to 31% nickel and 20% to 22% chromium, a high-nickel austenitic grade used in demanding chemical, marine, and energy applications. Over the decade from 2015 to 2025, the EU's trade in this specialty product underwent a dramatic contraction in volumes, a fundamental restructuring of its partner landscape, and a shift from near self-sufficiency to a position of moderate net import reliance. The report is organised around three central dynamics observed in the data.

1. A Market in Structural Contraction: Volumes Down, Prices Up

Both import and export volumes fell sharply over the decade

The most striking feature of EU trade in CN 72230011 is the sheer magnitude of its contraction. On the trade overview, import volumes fell 71.9%, from 1,974 tonnes in 2015 to just 555 tonnes in 2025. Export volumes declined by 60.3%, from 523 tonnes to 207 tonnes. The trade deficit, measured in value, narrowed by 44.2% — not because the EU became more competitive, but because both sides of the ledger contracted simultaneously.

Unit prices diverged: imports became more expensive while export prices softened

A key asymmetry in the price dynamics underscores the structural shift. Import prices rose 42.0%, from €4,430/t to €6,291/t, reflecting both global raw-material cost pressures (nickel and chromium are volatile commodities) and a possible shift in the quality mix or sourcing profile. By contrast, export prices declined by 15.1%, from €12,015/t to €10,197/t. The persistent price premium of EU exports over imports (roughly 1.6× in 2025) suggests the EU continues to specialise in higher-specification or further-processed wire, but this premium narrowed over the decade.

EU domestic production volumes declined even as production value increased

Available production data paints a consistent picture: domestic production volumes (proxied by the Prodcom code 24.34.12.00) fell 33.5% from 270.7 million kg to 180.0 million kg, while the value of that production rose 17.4% from €639 million to €750 million. This divergence between volume and value is consistent with input cost inflation and a possible move toward higher-value product grades, but it also means that the EU is producing substantially less stainless steel wire than it did at the start of the period.

2. A Radical Reconfiguration of Trade Partnerships

Switzerland's collapse as the dominant import source was the single largest structural shift

In 2015, Switzerland accounted for the vast majority of EU imports, supplying €6.8 million out of €8.7 million total. By 2025, Swiss shipments had collapsed by 93.4% to just €451,000. This single partner's decline explains most of the overall import contraction. The likely driver is the restructuring or relocation of Swiss-based specialty steel processing capacity (several major European wire-drawing groups have production sites in both Switzerland and EU member states).

China and Brazil emerged as new or rapidly growing import suppliers

As Switzerland receded, China's share of EU imports grew by 303.7%, from €367,000 to €1.48 million — making China the largest single import partner by value in 2025. Brazil appeared almost from scratch (€6 in 2015) to reach €404,000 in 2025. Russia also grew from €25,000 to €194,000 (+688.6%). The import concentration index (HHI) fell from 6,193 to 2,551, confirming that the formerly Swiss-dominated supply base has diversified considerably — though this diversification has come with higher price volatility from newer suppliers (China's coefficient of variation stands at 0.61, Brazil's at 0.83).

Traditional EU export markets contracted severely, with only a few destinations growing

The EU's export partner profile also experienced dramatic reshuffling. The United States — the largest export destination in 2015 at nearly €2.0 million — shrank by 77.5% to €441,000. The United Kingdom (−89.1%), China (−89.8%), and Russia (−96.7%) all saw collapses of similar or greater magnitude. Only two partners bucked the trend: Türkiye grew from €541,000 to €691,000 (+27.8%), and Brazil surged from €10,000 to €143,000 (+1,300.2%). Notably, a severe price shock in 2017 in exports to the United States (abnormality score of 6.8, price shift of +379.8%) may have contributed to the subsequent erosion of that market.

Within the EU, the geography of trade also shifted

Among EU member states reporting trade, Italy's imports collapsed from €4.7 million to €195,000 (−95.9%) and Hungary's from €355,000 to €4,600 (−98.7%). Meanwhile, Ireland's imports surged by 898% (from €74,000 to €736,000), suggesting a possible relocation of downstream processing activity. On the export side, the Netherlands, Ireland, Italy, and Sweden all saw declines exceeding 69%, while Germany retained a relatively more stable export base (−31.6%).

3. From Near Self-Sufficiency to Growing Import Dependence

The EU shifted from a position of marginal net self-sufficiency to one of moderate import reliance

The most consequential structural change revealed by the net import reliance metric is the EU's transition from a near-zero or slightly negative value (−1.0% in 2015, meaning marginal net self-sufficiency) to +12.2% in 2025. The peak was reached at 24.1% at some point during the decade. This means the EU now structurally depends on non-EU sources for roughly one-eighth of its consumption of this specialty wire — a noteworthy vulnerability for a product used in critical chemical and energy infrastructure.

Trade intensity and export propensity both doubled, signalling deepening international integration

The trade intensity ratio (the sum of imports and exports divided by production value) rose from 28.4% to 58.8%, more than doubling. The export propensity (exports as a share of production value) climbed from 17.0% to 37.6%. These increases are not necessarily signs of strength: they partly reflect the contraction of the domestic production denominator, which mechanically inflates both ratios. In other words, the EU is trading more relative to what it produces — but it is producing less in absolute terms.

The partner concentration landscape shifted from one dominant supplier to a more fragmented — but volatile — base

The Herfindahl-Hirschman Index for imports fell 58.8% from 6,193 to 2,551, moving from a highly concentrated (near-monopolistic) import structure to a moderately concentrated one. This might appear to reduce vulnerability, but the new suppliers display significantly higher price volatility: Brazil (CV 0.83), the United States (CV 0.95), Taiwan (CV 0.96), and Mexico (CV 1.84) all show far greater instability than Switzerland once did. The most specialised EU producer remains the Netherlands (RCA of 6.1, RSCA of +0.72), but its export volumes have also declined. Most other EU member states show negative RSCA values, indicating they are net importers of this product category.

Conclusion

The EU's trade in CN 72230011 over 2015–2025 tells the story of a specialty niche market undergoing profound structural change. Volumes on both the import and export sides have contracted dramatically — by 60–72% — while unit prices have generally risen, reflecting raw-material cost pressures and a possible shift in product mix. The most consequential change has been the near-total withdrawal of Switzerland as the EU's primary import source and its replacement by a more fragmented supplier base centred on China, Brazil, and several other emerging origins. This diversification has reduced single-partner concentration risk but introduced higher price volatility from less predictable suppliers.

At the macro level, the EU has shifted from near self-sufficiency to a position of moderate net import dependence (12.2% in 2025), while domestic production volumes have declined by a third. For a product used in high-performance chemical, energy, and marine applications, this growing reliance on external supply — coupled with the observed price shocks in trade with Russia (2020) and China (2022) — warrants attention from policymakers concerned with strategic industrial autonomy.
