Market evolution: Parts and accessories for chapter 90 (CN 9033) — 2015–2025

Introduction

This report analyzes the evolution of European Union trade in CN 9033, which covers parts and accessories for machines, appliances, instruments, and other apparatus in chapter 90 not specified elsewhere. Over the 2015–2025 period, the EU solidified its position as a net exporter in this sector. While the total value of both exports and imports increased, the underlying dynamics reveal a significant shift: EU exports became increasingly high-value, while import volumes grew rapidly, albeit from different sources and at lower prices. The period was also marked by a notable post-pandemic restructuring of supply chains and trade partnerships.

1. A Tale of Two Currents: Value Growth Amidst Divergent Volume Trends

The headline figures show overall growth, but a deeper look reveals a clear divergence in the trajectories of the EU's export and import flows.

EU exports captured significantly higher value despite lower volumes

EU exports of CN 9033 parts increased in value by 35.3% over the decade, from €370 million in 2015 to €501 million in 2025. However, this growth was driven entirely by higher prices. The quantity exported actually fell by 10.3%, from 5,503 tonnes to 4,934 tonnes. Consequently, the unit export price surged by 50.7%, from approximately €67,269 per tonne to €101,360 per tonne. This indicates a shift towards exporting more specialized, high-technology, or higher-margin components.

Import growth was volume-driven, reflecting changing sourcing strategies

In contrast, EU imports grew more modestly in value (19.9%, from €232 million to €278 million), but this was backed by a substantial 57.3% increase in quantity, from 3,624 tonnes to 5,700 tonnes. As a result, the average import price fell by 23.8%, from €63,876 to €48,686 per tonne. This suggests that the EU increasingly sourced standard or cost-competitive components from abroad, or that supply chains for these parts expanded significantly.

The EU's trade surplus widened substantially

Driven by this value-volume divergence, the EU's trade balance in CN 9033 strengthened markedly. The surplus grew by 61.1%, from €139 million in 2015 to €223 million in 2025, underlining the sector's positive net trade position.

2. Shifting Geographic Dependencies and Internal Rebalancing

The decade saw a significant reconfiguration of the EU's trade partners, both within its borders and externally, characterized by a decline in reliance on some traditional partners and a rise of new ones.

External partnerships were reshaped by cost, proximity, and geopolitics

The top partner rankings changed considerably. On the import side, China's share of EU imports grew dramatically (by 151.9% in value), while imports from the UK declined (-40.8%). Notably, imports from Türkiye (+419.7%) and Taiwan (+227.9%) surged, pointing to diversified sourcing. For exports, the United States remained the dominant destination, with its import value from the EU growing by 56.3%. Exports to China also grew robustly (+56.2%). A major decline was seen in exports to Russia (-71.5%), reflecting the impact of sanctions following 2022.

EU internal production expanded rapidly, led by Germany and Italy

Domestic production value within the EU more than doubled, rising by 127.1% from €1.94 billion to an estimated €4.4 billion. This expansion was spearheaded by Germany, which increased its exports from €130 million to €172 million (+32.6%). Italy's export performance was even more impressive, growing from €35 million to €83 million (+134.0%). This growth in production and exports from core economies supported the overall high-value export trend.

Specialization patterns indicate an East-West production divide

Analysis of revealed comparative advantage shows a geographic split within the EU. Eastern European members like Bulgaria and Romania displayed the highest specialization in exporting CN 9033 parts in 2025, suggesting these countries have developed strong roles as production platforms for these components. In contrast, major economies like Belgium and Ireland showed low specialization, indicating their trade in this product category is more aligned with general industrial needs rather than focused production.

3. Resilience Tested by Volatility, Underpinned by Strategic Shifts

The period witnessed significant market volatility and specific supply shocks, yet the underlying structure of EU trade showed signs of increased diversification and strategic positioning.

Import sourcing became more diversified, while export markets remained stable

The Herfindahl-Hirschman Index (HHI) for imports by value fell by 15.7%, from 1,603 to 1,351, indicating a reduction in concentration and greater diversification of sourcing partners—a positive trend for supply chain resilience. The HHI for exports remained relatively stable, suggesting the EU maintained a consistent export portfolio.

Key partnerships experienced high volatility and acute price shocks

Volatility, measured by the coefficient of variation, was high in specific bilateral relationships. Notably, imports from Türkiye (CV: 0.63) and exports to Morocco (CV: 0.75) and Russia (CV: 0.61) were highly unstable over the decade. The analysis also detected specific price shocks: an extreme export price spike to Algeria in 2022 (abnormality: 13.8), a sharp import price increase from Türkiye in 2021, and an export price surge to the UK in 2021. These events highlight periods of significant market disruption.

Details on volatility and detected shocks are available here.

The EU strengthened its net exporter status despite high trade intensity

The EU's net import reliance metric remained deeply negative (from -32.3% to -38.0%), confirming its consistent position as a net exporter. While trade intensity (exports+imports as a share of production) and export propensity remained high (both above 100% in 2025), they have slightly decreased from their 2015 peaks. This, coupled with the massive growth in domestic production, suggests a gradual increase in the use of locally produced components relative to the overall scale of trade, enhancing the bloc's strategic autonomy in this segment.

Conclusion

The EU's market for CN 9033 parts evolved significantly between 2015 and 2025. The overarching narrative is one of value over volume in exports and volume-driven expansion in imports. The EU successfully capitalized on its high-technology industrial base to sell increasingly valuable components, particularly to the US and China, even as overall export tonnage declined. Concurrently, it integrated a larger volume of parts into its production systems from a more diversified set of suppliers, notably from Asia and emerging European producers.

Internally, a production renaissance, led by Germany and Italy but with growing specialization in Eastern Europe, supported the EU's strong net export position. While the market faced volatility and geoeconomic shocks—most visibly the collapse of exports to Russia—the data indicates that import diversification and robust internal production provided a degree of resilience. Looking forward, the challenge will be to sustain the high-value export edge while managing the strategic dependencies revealed by the rapid growth in imports from a small number of key third countries.
