Market evolution: Rolling mill parts (CN 845590) — 2015–2025

Introduction

This report analyses the evolution of the European Union's trade in parts for metal-rolling mills (customs code 845590) over the period from 2015 to 2025. The EU is a major global producer and net exporter in this sector, but the period witnessed significant shifts in trade value, geographical patterns, and competitive dynamics. The analysis is based on annual trade data between the EU and non-EU countries. Key trends include strong value growth driven predominantly by rising unit prices, a notable reorientation of export and import partners, and changes in the sector's international competitive posture.

1. Price-Driven Value Growth Sustains Trade Surplus

The EU's trade in rolling mill parts experienced robust growth in value terms over the 2015-2025 period, primarily driven by increasing unit prices rather than physical volumes. This price escalation sustained a consistent trade surplus despite fluctuating quantities.

Export value rises as unit prices climb, offsetting volume declines

The total value of EU exports to non-EU countries increased by 21.8%, from €526.2 million in 2015 to €641.0 million in 2025. However, this growth was achieved entirely through price increases. Export quantity fell by 10.8%, from 35,616 tonnes to 31,762 tonnes. Consequently, the average export price surged by 36.6%, from €14,773 per tonne to €20,181 per tonne (General Overview).

Import value growth is even steeper, fueled by both price and partner shifts

The value of EU imports saw a much sharper increase of 68.0%, rising from €81.7 million to €137.2 million. Similar to exports, import volume decreased by 9.6% (from 21,737 to 19,656 tonnes), meaning the 85.8% jump in the average import price—from €3,755 to €6,978 per tonne—was the dominant factor (General Overview).

The EU maintains a significant and growing trade surplus

Despite faster import value growth, the EU's trade surplus expanded by 13.3% over the period, from €444.5 million to €503.8 million. This indicates the EU's export specialization in higher-value segments of the market, allowing it to offset rising import costs. The net import reliance remained deeply negative (from -604% to -246%), confirming the EU's strong net exporter status, although the improvement suggests a relative increase in import dependence.

2. A Deepening Geographic Pivot: US as Anchor, China's Dual Role Intensifies

The 2015-2025 period was characterized by a dramatic reorientation of trade flows. The United States solidified its position as the EU's primary export market, while China became the dominant source of imports, leading to a significant increase in trade concentration.

The US becomes the indispensable export market for EU producers

Exports to the United States grew by 197.6% to €208.0 million, making it by far the largest destination, accounting for a substantial share of total exports. Other key partners like Mexico (+233.5%) and Türkiye (+23.1%) also grew, while exports to the Russian Federation collapsed by 87.3%, likely reflecting geopolitical sanctions (General Overview).

China transforms from a key export destination to the largest import source

The most profound shift occurred with China. While EU exports to China fell by 12.6% to €51.0 million, imports from China surged by 265.2% to €80.9 million, making China the top import partner. This indicates China's growing role not just as a market, but as a formidable competitor supplying the EU internal market. In contrast, imports from the United States fell by 77.9% (General Overview).

Trade concentration increases for both exports and imports

The concentration of trade partners (measured by the Herfindahl-Hirschman Index, HHI) increased markedly. For exports, the HHI more than doubled (+125.0%), while for imports, it increased by 69.3%. This signifies a growing reliance on fewer key partners, amplifying exposure to specific geopolitical and economic risks in those markets and sources.

3. Specialization Endures but External Vulnerability Rises

While the EU's core producing nations maintain a specialized industry, the decade's trade patterns reveal increased vulnerability to external price shocks and a potential erosion in relative competitive strength, despite strong domestic production growth.

Production grows strongly in value, mirroring export price trends

EU production value increased by 73.3% over the period, from €450 million to €780 million. This aligns with the observed export price inflation, suggesting the industry successfully passed on higher costs or produced more sophisticated, higher-value goods.

Italy, Austria, and Germany remain the specialized production core

Specialization data for 2025 shows Italy (RCA of 4.96), Austria (3.76), and Germany (1.39) have the highest Revealed Comparative Advantage indices. Italy alone accounts for nearly 40% of EU production in this product group. However, Germany's RCA, while positive, is relatively modest, indicating its diversified industrial base.

Price volatility and supply shocks expose vulnerabilities

Trade is subject to significant volatility, particularly in imports from certain partners (e.g., the United States with a Coefficient of Variation of 2.53) and exports to others (e.g., Algeria at 1.93). The data detects several severe price shocks, including a 199.8% abnormal price increase for imports from Switzerland in 2018 and a 414.6% spike for exports to Morocco in 2021. These events highlight the sector's susceptibility to sudden market disruptions.

Competitiveness indicators show a subtle weakening

The net import reliance metric improving (becoming less negative) by 59.2% suggests the EU's position as a net exporter has weakened relative to its import needs. Concurrently, the trade intensity and export propensity remained exceptionally high (over 90%), confirming the industry's deep integration into global value chains but also its exposure to international market dynamics.

Conclusion

Over the 2015-2025 period, the EU's trade in rolling mill parts (CN 845590) grew in value, driven overwhelmingly by rising unit prices which compensated for falling volumes in both exports and imports. The EU maintained its status as a major net exporter, but the decade was marked by a decisive geographic pivot: exports became heavily concentrated on the United States, while imports surged from China, making the EU market more dependent on Chinese supply.

Internally, core producers like Italy and Austria upheld strong specialization, and domestic production value grew robustly. However, the increasing concentration of trade partners, exposure to severe price shocks, and a relative decline in net export surplus point to a sector navigating a changing and more volatile global competitive landscape. The data suggests an industry successfully monetizing its niche through higher prices but facing new structural challenges in its trade relationships.
