Market evolution: Multi-component integrated circuits (CN 85423911) — 2015–2025

Introduction

This report examines the European Union's trade dynamics for custom code 85423911 — electronic multi-component integrated circuits (MCOs) as specified in note 12(b)(4) to chapter 85, excluding processors, controllers, memories, and amplifiers. The product scope covers a niche yet strategically significant segment of the semiconductor value chain, encompassing hybrid and system-in-package devices increasingly central to automotive, industrial, and IoT applications.

Data is available from 2017 through 2025. Over this period, EU trade in MCOs has undergone a profound transformation: total trade values have roughly tripled, the EU has shifted from marginal deficit to sustained surplus, and the geographic and structural composition of trade flows has been reshaped. Domestic production volumes have expanded by an order of magnitude.

The following three sections interpret these dynamics in turn: the scale and direction of trade growth, the shifting structure of EU specialisation and partner geography, and the emerging vulnerabilities exposed by volatility and import reliance.

I. Explosive Growth in Trade Volumes and the EU's Emergence as a Net Exporter

The most striking feature of the 2017–2025 period is the sheer magnitude of growth in both trade flows. EU exports rose from €415 million in 2017 to €1,113 million in 2025 (+168%), while imports grew from €402 million to €970 million (+141%). The EU's trade balance swung from a marginal surplus of €13 million in 2017 to a sustained surplus of €143 million by 2025, after hitting a trough deficit of −€419 million at some intermediate point — suggesting a structural shift in competitive positioning.

Export volumes grew far faster than import volumes, altering the EU's trade profile

The most dramatic divergence is in physical quantities. Export tonnage surged by 738% (from 77 tonnes to 644 tonnes), while import tonnage grew by a comparatively modest 76% (from 480 tonnes to 842 tonnes). This indicates that the EU has rapidly scaled up its role as a physical exporter of MCOs, not merely as a high-value re-exporter.

Unit-price trends reveal a structural shift in the product mix

Export prices fell by 68% (from €5.4 million per tonne to €1.7 million per tonne), while import prices rose by 37% (from €838,000 to €1.15 million per tonne). This convergence is striking: the EU historically exported very high-value-per-kilogramme devices (likely specialised or niche MCOs), while importing lower-value components. The narrowing price gap suggests the EU has broadened its export base into higher-volume, somewhat lower-value products — consistent with the scaling of production for automotive and industrial applications — while importers have shifted toward somewhat higher-value products.

Domestic production scaled dramatically, underpinning export growth

EU production of MCOs expanded from approximately 255 million units to 4 billion units (+1,471%), while production value quadrupled from €400 million to €1.6 billion (+300%). This fifteen-fold increase in volume alongside a four-fold increase in value confirms the export-price story: the EU is producing far more units at lower average value, consistent with the maturation of automotive-grade MCO manufacturing. The scaling of domestic capacity has been essential to sustaining the export surge without proportionate increases in imports.

II. Geographic Diversification and the Rise of Asia-Pacific Supply Chains

The geographic concentration of EU imports has declined meaningfully: the Herfindahl-Hirschman Index (HHI) by value fell from 2,268 to 1,735 (−24%), and by volume from 2,072 to 1,489 (−28%). In export markets, concentration by value remained broadly stable (HHI around 1,500–1,590). This import-side diversification reflects the emergence of new supplier countries alongside traditional sources.

The Philippines remained the EU's largest single import source, but its dominance eroded

*From a near-zero base of €1,377.

The Philippines nearly doubled its exports to the EU — a strong absolute performance — but its relative share declined as Malaysia, China, Taiwan, and Thailand all grew much faster. Malaysia's import growth of +399% and China's of +778% are particularly noteworthy, reflecting both the expansion of OSAT (outsourced semiconductor assembly and test) capacity in Southeast Asia and China's rising role in advanced packaging.

Korea's imports were essentially flat (+6%), suggesting mature and stable sourcing relationships for specific MCO types.

Export markets shifted dramatically toward Asia, with Hong Kong emerging as a major transit hub

The most dramatic shift in EU export destinations was the surge in shipments to Hong Kong (+9,136%) and Malaysia (+963%). Hong Kong's explosive growth — from €2 million to €187 million — likely reflects re-export flows to mainland China and broader East Asian assembly operations, consistent with Hong Kong's traditional role as a semiconductor logistics hub. Malaysia's rise as the EU's single largest export destination (€202 million) aligns with its position as a global OSAT centre, where EU-origin MCOs may undergo further packaging or be integrated into larger modules.

The United States, while still a major market, saw more modest growth (+101%), and the United Kingdom grew at just +84%, suggesting that transatlantic and post-Brexit demand patterns evolved more slowly than Asian demand.

EU specialisation is heavily concentrated in Germany, with limited spread

Specialisation analysis for 2025 shows that Germany dominates EU production, with a Revealed Symmetric Comparative Advantage (RSCA) of 0.60 and an RCA of 3.98, accounting for 84% of EU production value. Hungary (RSCA 0.49, RCA 2.96) is the only other member state with notable specialisation. At the other end, Bulgaria, Luxembourg, Slovakia, Lithuania, and Croatia show near-zero specialisation, indicating that MCO manufacturing remains an activity of a handful of EU economies — primarily Germany's automotive-electronics ecosystem.

Germany was also the EU's dominant trading member: its imports rose from €374 million to €846 million (+126%), and its exports from €398 million to €919 million (+131%). Austria, Belgium, Hungary, and Spain all showed very high growth rates from much smaller bases, suggesting emerging specialisation in some newer member states and smaller economies.

III. Rising External Dependence Amid Persistent Volatility and Supply Shocks

Despite the EU's success in scaling exports and diversifying import sources, vulnerability indicators have worsened. Net import reliance — net imports as a share of apparent consumption — rose from 10.0% to 17.2% (+73%), and at its peak reached 47.8%, indicating periods of significant external dependence. Trade intensity nearly tripled from 29.7% to 84.8%, and export propensity surged from 12.9% to 70.8%.

The EU's MCO trade has become deeply integrated into global supply chains

These figures tell a consistent story: the EU's MCO sector is now far more exposed to international trade flows than it was in 2017. Export propensity — the share of domestic production that is exported — has risen from under 13% to over 70%, meaning the vast majority of EU-manufactured MCOs are destined for foreign markets. While this reflects competitive success, it also implies greater sensitivity to global demand shocks, trade policy changes, and logistics disruptions.

Import volatility is highest for smaller or emerging suppliers, while major partners are relatively stable

Volatility analysis measured by coefficient of variation (CV) reveals distinct risk profiles among import partners:

The Philippines, as the EU's largest import source, also exhibited the lowest volatility (CV 0.19), suggesting deeply embedded and stable supply relationships. By contrast, emerging sources such as Serbia, Indonesia, and Türkiye showed high volatility — predictable given their small and rapidly growing trade volumes.

On the export side, volatility was highest for Hong Kong (CV 1.65), Malaysia (1.62), and the Philippines (1.36) — all fast-growing Asian markets subject to inventory cycles and demand swings.

The 2022 semiconductor cycle produced detectable supply and price shocks

Shock detection identified three significant events clustered around 2022:

The 2022 price shock in EU exports to Malaysia — a 133% price shift with an abnormality score of 78.4 — is consistent with the global semiconductor pricing dynamics of the 2021–2022 shortage period, when acute demand from automotive and industrial customers drove up MCO prices. The simultaneous supply shock (−72% volume decline) to Malaysia suggests either demand destruction from extreme pricing or allocation constraints. The co-occurrence of price and supply shocks to the same partner in the same year points to the classic pattern of the semiconductor cycle: shortage-driven price spikes followed by demand contraction.

Conclusion

Over the 2017–2025 period, the EU's trade in multi-component integrated circuits (CN 85423911) has undergone a structural transformation. Total trade values roughly tripled, the EU shifted from trade deficit to sustained surplus, and domestic production scaled by a factor of fifteen. This growth was powered primarily by Germany, which accounts for over 84% of EU production and dominates both import and export flows.

The geographic centre of gravity has tilted decisively toward the Asia-Pacific region. Malaysia, China, Taiwan, and Thailand have emerged as major import suppliers alongside the Philippines, while EU exports have surged toward Hong Kong, Malaysia, China, and Mexico. Import concentration has declined, indicating healthier diversification, though the EU remains dependent on a relatively small number of Asian packaging and assembly hubs.

However, this success has come with growing exposure. Trade intensity and export propensity have both risen dramatically, meaning the EU's MCO sector is now deeply enmeshed in global value chains and sensitive to external disruptions. Net import reliance has increased, and the 2022 semiconductor cycle produced detectable price and supply shocks. Looking ahead, the EU's strategic challenge will be to sustain its competitive gains while managing the vulnerabilities inherent in an increasingly trade-dependent semiconductor ecosystem.
