Market evolution: Stainless steel rectangular semi-finished products (CN 721891) — 2015–2025

Introduction

This report analyses the trade performance of the European Union in semi-finished products of stainless steel with a rectangular (non-square) cross-section (CN code 721891) over the period 2015–2025. The data reveals a profound structural shift in the EU's trade position, characterized by a dramatic expansion of imports that far outpaced exports, fundamentally altering the region's market dynamics.

A Paradigm Shift: From Balanced Trade to Import Dominance

The EU's trade in this product category underwent a radical transformation over the decade. While exports grew moderately in value, they stagnated in volume, whereas imports exploded in both dimensions, leading to a deepening structural trade deficit.

Import Volume and Value Surged to Record Levels

EU imports increased overwhelmingly over the period. Import quantity grew by 324.8%, from 106,095 tonnes in 2015 to 450,677 tonnes in 2025. This volumetric expansion, combined with rising unit prices, propelled import value to an increase of 265.9%, reaching €777.3 million in 2025 from €212.4 million in 2015. The unit import price itself showed volatility but ended the period slightly lower than its starting point, indicating the value growth was primarily volume-driven after 2020 (General Overview trade).

Export Growth Was Muted and Price-Driven

In contrast, EU exports showed minimal growth. Export volume increased by only 2.1% over the entire period, from 6,062 tonnes to 6,189 tonnes. The significant growth in export value (+71.3% to €34.4 million) was almost entirely due to a 67.7% increase in unit export prices, indicating that the EU maintained a competitive position in higher-value niches but failed to expand its global market share in terms of volume (General Overview trade).

The Trade Balance Worsened Dramatically

The divergence between soaring imports and stagnant exports caused the EU's trade deficit to widen from €-192.3 million in 2015 to €-742.9 million in 2025, a deterioration of 286.3%. This highlights the EU's transition from a relatively balanced market to one with significant net import reliance, which stood at 58.2% in 2025 (General Overview balance_eur, Net import reliance).

The New Geography of Trade: Emerging Suppliers and Concentrated Customers

The map of EU trade partners was redrawn during this period, with supply sources becoming more diversified while export destinations remained focused.

Import Sources: The Meteoric Rise of Indonesia and a More Diversified Portfolio

The concentration of EU imports (measured by the Herfindahl-Hirschman Index on value) fell sharply by 48.1%, indicating a diversification of supply sources. The most striking development was the emergence of Indonesia as a dominant supplier. Import value from Indonesia skyrocketed from a negligible €98 in 2015 to €461.6 million in 2025, making it the EU's top supplier by value in the latest year. The United Kingdom remained a major but relatively stable supplier (+47.6% to €312.1 million). Other suppliers like South Korea and Russia showed high volatility (Top import partners, Volatility bars imports).

Export Markets: Stability Among Key Partners, with the US and UK Leading

EU exports were more concentrated and showed lower volatility. The United States and the United Kingdom remained the two most important customers, together accounting for the vast majority of exports. Exports to the US grew by 44.0% to €19.9 million, while those to the UK more than doubled (+131.3% to €8.8 million). Exports to Russia collapsed by 77.8%, likely due to geopolitical factors (Top export partners).

Internal EU Dynamics: Italy and Belgium Became Major Import Hubs

Within the EU, the geography of imports shifted significantly. Italy saw an astronomical increase in reported imports, from €218,305 in 2015 to €428.5 million in 2025, becoming the largest importing member state. Belgium also witnessed a massive surge to €262.2 million. Conversely, traditional hubs like Sweden saw their share of imports decline sharply. On the export side, Sweden consolidated its position as the EU's leading exporter, growing its value by 63.0% to €27.9 million (Top reporter countries).

Industrial Strategy and Product Specialization

Underlying the trade flows are trends in production and product mix that point to a changing industrial strategy within the EU bloc.

EU Production Grew in Volume but Less So in Value

EU production of these semi-finished products increased by 148.6% in volume (from 210 million kg to 522 million kg) and by 40.0% in value over the period. This indicates an expansion in physical output, but the lower growth in value suggests possible margin pressure or a shift in the product mix toward lower-value items domestically (Production volumes).

The Market Specializes in High-Nickel Grades

The data reveals a clear specialization in the high-nickel sub-product (CN 72189110). In 2025, this grade accounted for 99.7% of import volume and 74.2% of export volume. This specialization is driven by the EU's strong competitive advantage in this segment: in 2025, Finland and Sweden showed very high Revealed Symmetric Comparative Advantage (RSCA) scores of 0.886 and 0.825, respectively. Their production is heavily oriented towards this niche, which commands higher prices (€1,723/t for imports vs. €2,117/t for the low-nickel grade in 2025) (Most specialised reporters, Product segment breakdown).

A Declining Export Propensity Highlights a Domestic Reorientation

A critical indicator is the EU's export propensity—the share of production exported—which plummeted from 24.2% in 2015 to a mere 9.1% in 2025. This 62.5% decrease is the most salient vulnerability metric and strongly suggests that the significant increase in EU production capacity has been absorbed by the domestic market, likely displacing imports in some segments, while the export orientation of the industry has weakened substantially (Export propensity).

Conclusion

Over the 2015–2025 period, the EU's market for rectangular stainless steel semi-finished products was defined by a dramatic import surge, led by the emergence of Indonesia as a dominant supplier, which overwhelmed modest export growth. This turned the EU into a significantly net-import-reliant region. Internally, production expanded but became more inward-looking, as evidenced by a collapse in export propensity. The industry has specialized in high-nickel grades, where certain member states retain a strong comparative advantage. The key dynamic is therefore a paradox: while the EU's industrial base in this sector grew in physical terms, its global trade footprint shrank, deepening its dependence on external suppliers for the bulk of its consumption needs.
