Market evolution: Computer parts (CN 847330) — 2015–2025

Introduction

This report examines the evolution of EU external trade in CN 847330 — Parts and accessories of automatic data-processing machines or for other machines of heading 8471, n.e.s. — over the period 2015 to 2025. The heading covers a broad range of computer components, from motherboards and graphics cards to connectors and printed circuit assemblies. It is a critical product category for the EU's digital-economy supply chain and encompasses two subcategories: electronic assemblies (CN 84733020) and other parts and accessories (CN 84733080).

Over the past decade, the EU's trade in this category has undergone a profound structural transformation. Import values nearly doubled to €16.9 billion, while the trade deficit more than doubled to €10.9 billion. Yet these headline figures conceal a more complex story involving a dramatic shift in product composition toward higher-value electronic assemblies, a geopolitical reshuffling of sourcing away from China and the UK toward Vietnam, Mexico and Taiwan, and a declining export orientation that raises questions about the EU's evolving role in global computer-parts value chains.

A Surge in Value Unmoored from Volume: The Price-Driven Transformation of EU Trade

Import values nearly doubled while physical volumes stagnated

The most striking feature of EU trade in CN 847330 over 2015–2025 is the stark divergence between value and volume. Import values rose from €8.8 billion in 2015 to €16.9 billion in 2025 (+91.6%), while import quantities fell from 155,264 tonnes to 138,084 tonnes (−11.1%). This implies that average import unit values more than doubled, climbing from €56,968 per tonne to €122,696 per tonne (+115.4%). On the export side, a similar pattern emerged: export value grew from €4.5 billion to €6.0 billion (+33.7%), but export volumes contracted sharply from 36,485 tonnes to 24,621 tonnes (−32.5%), pushing export unit values from €123,926 per tonne to €245,493 per tonne (+98.1%).

The trade deficit widened from −€4.3 billion in 2015 to −€10.9 billion in 2025 (−152.1%). This deficit expansion was driven almost entirely by value appreciation rather than by an increase in the physical quantity of goods consumed domestically.

Electronic assemblies account for the overwhelming majority of the value surge

The product segment breakdown reveals that the compositional shift toward high-value electronic assemblies (CN 84733020) is the single most important driver of this trend.

Electronic assemblies saw their import unit value more than double to €354,287 per tonne by 2025 — nearly ten times the unit value of other parts (€38,469/t). By 2025, electronic assemblies represented 77% of total import value (up from 66% in 2015) while accounting for only 27% of import volume. This reflects the broader technological trend toward miniaturisation and integration: modern electronic assemblies (graphics cards, memory modules, server components) pack vastly more value per kilogramme than mechanical or passive parts.

Global semiconductor shortages and post-pandemic demand amplified price dynamics

The period 2020–2022 saw acute global semiconductor shortages that drove up prices for electronic assemblies worldwide. Import unit values for electronic assemblies surged from €217,089/t in 2020 to €283,111/t in 2022, then accelerated further to €354,287/t by 2025 — suggesting that even after supply normalisation, structural price increases persisted. A detected price shock in Chinese imports around 2017 (abnormality score: 8.3, shift: +47.4%) may have been an early signal of the supply-chain tightening that would intensify in subsequent years.

Geopolitical Rewiring: From China–UK Dependence to a Fragmented Supplier Map

Import sourcing shifted dramatically toward Southeast Asia and Mexico

The geographic composition of EU imports underwent a profound restructuring between 2015 and 2025.

China remains the EU's largest single supplier, but its import value grew only 13.8% — far below the overall import growth rate of 91.6% — implying a significant loss of market share. Meanwhile, Taiwan (+470.3%), Vietnam (+1,875.0%) and Mexico (+864.6%) emerged as major new sourcing hubs. This triangulation reflects several overlapping dynamics: the US–China trade tensions that began in 2018 prompted manufacturers to relocate assembly capacity to Vietnam and Mexico; the EU's own diversification efforts under "strategic autonomy" initiatives encouraged sourcing from alternative partners; and Taiwan's dominant position in semiconductor manufacturing (particularly for TSMC and its ecosystem) translated into surging exports of advanced electronic assemblies.

The UK's collapse as a sourcing partner illustrates Brexit's lasting trade effects

The United Kingdom's imports by the EU fell from €1.4 billion to €109 million (−92.0%), representing one of the most dramatic shifts in the dataset. The volatility analysis confirms this was not a gradual erosion but an erratic, high-variance transition (coefficient of variation: 0.74). The sharp decline is consistent with the UK's departure from the EU customs union in January 2021, which introduced customs declarations, rules-of-origin requirements and regulatory checks on goods flows that were previously frictionless. Much of the trade formerly recorded as UK-sourced likely redirected through EU member states (notably the Netherlands) or was re-routed through Asian suppliers directly.

Import concentration decreased substantially as supply chains diversified

The Herfindahl-Hirschman Index (HHI) for imports fell from 2,991 in 2015 to 1,845 in 2025 (−38.3%). While the starting level indicated moderate concentration, the ending level reflects a considerably more diversified supplier base. This is a positive development for supply-chain resilience, though it masks the fact that much of the new sourcing originates from subsidiaries of the same multinational companies (e.g., Foxconn, Pegatron) that have simply relocated assembly lines from China to Vietnam or Mexico.

Export markets narrowed, and Russia disappeared entirely

On the export side, the picture diverges sharply from imports.

The complete collapse of exports to Russia (from €232 million to €133,000, −99.9%) is directly attributable to EU sanctions imposed following Russia's invasion of Ukraine in February 2022. This constitutes a supply shock with an abnormality score of 2.6. Conversely, the United States emerged as the EU's dominant export market, with shipments growing from €416 million to €1.5 billion (+265.7%). Export market concentration increased slightly (HHI from 876 to 1,153, +31.6%), partly reflecting Russia's exit and the growing weight of the US.

Strategic Repositioning: The EU as Consumer, Assembler and Distributor

EU production grew but could not keep pace with import expansion

EU domestic production of CN 847330 rose from €6.1 billion to €7.9 billion (+30.1%). However, this growth was substantially outpaced by the 91.6% increase in imports, implying that the EU's net import reliance, while declining slightly from 60.3% to 56.2%, remained elevated. The EU produces significant volumes of computer parts — particularly through specialised hubs in the Netherlands, Ireland, Czechia and Germany — but it is increasingly reliant on non-EU sources for the most technologically advanced components.

The Netherlands and Ireland have consolidated their roles as EU trade hubs

The most specialised EU Member States in CN 847330 are Ireland (RSCA: 0.58, RCA: 3.74) and the Netherlands (RSCA: 0.54, RCA: 3.33). The Netherlands' import value surged from €2.0 billion to €5.3 billion (+172.1%), and its exports grew from €2.0 billion to €2.9 billion (+48.1%). Ireland's imports exploded from €970 million to €3.4 billion (+252.0%). These figures suggest both countries function as critical nodes in the EU's computer-parts supply chain — importing large volumes of components (whether for assembly, integration into finished products, or re-export) and channelling them into European and global markets.

Central European states have also expanded significantly:

Hungary's import growth (+359.7%) stands out and is likely linked to its growing role as a manufacturing base for electronics assembly (e.g., Samsung SDI, Foxconn, and other contract manufacturers operating in the country). Germany, traditionally the EU's largest economy and manufacturing powerhouse, saw a modest decline in imports (−8.4%) and a sharp contraction in exports (from €707 million to €352 million, −50.2%), possibly reflecting shifting production patterns within multinational corporations.

The EU's export propensity has collapsed, signalling a fundamental role change

Perhaps the most consequential long-term trend is the dramatic decline in export propensity, which fell from 177.3% in 2015 to 60.2% in 2025 (−66.0%). Trade intensity also declined, from 118.0% to 86.2% (−26.9%). These indicators, which measure the ratio of trade flows to domestic production, suggest that the EU is increasingly consuming its own production domestically rather than exporting it. In 2015, the EU exported €4.5 billion against €6.1 billion of production — a ratio of 74%. By 2025, exports of €6.0 billion represented only 76% of a much larger production base of €7.9 billion, yet the relative export orientation has fallen when measured against total domestic absorption (production plus net imports).

This shift reflects a broader structural transformation: the EU is increasingly functioning as a consumer, integrator and distributor of computer parts rather than a net exporter. While EU production has grown in absolute terms, the faster growth of imports — particularly of high-value electronic assemblies — means the EU's role in global value chains for this product category has tilted downstream. This may not be inherently problematic if it reflects the EU's comparative advantage in assembling these components into higher-value final products (servers, data-centre equipment, industrial computing systems). However, the widening trade deficit (now exceeding €10.9 billion) and the declining export propensity warrant attention from a trade-policy and strategic-autonomy perspective.

Conclusion

Over 2015–2025, EU trade in computer parts (CN 847330) has been transformed along three interrelated dimensions. First, the value–volume divergence driven by the shift toward higher-value electronic assemblies has meant that trade values have surged even as physical quantities have stagnated or declined. Import unit values more than doubled, reflecting both compositional change and global price pressures in semiconductor supply chains. Second, the geographic reshuffling of imports away from China and the UK toward Vietnam, Taiwan and Mexico has diversified the EU's supplier base — a positive development for resilience — while the near-total loss of Russia as an export destination (due to sanctions) and the growing dominance of the US as an export market have concentrated export risk. Third, the EU's strategic positioning has shifted: domestic production has grown modestly, but the bloc has become more dependent on imports of sophisticated electronic assemblies and less oriented toward exporting, with export propensity falling by two-thirds.

The resulting picture is of an EU that remains deeply embedded in global computer-parts value chains but is increasingly positioned as a consumer and integrator rather than a producer-exporter. The trade deficit of €10.9 billion in 2025, while partly reflecting the high value-added embedded in imported electronic assemblies, underscores the EU's structural dependency on non-EU suppliers for a category of goods that is foundational to its digital economy. Future policy attention will likely focus on whether the EU can rebalance this equation — through reshoring of semiconductor manufacturing (e.g., under the EU Chips Act), diversification of export markets, or a shift toward higher-value segments where the EU retains a competitive edge.
