Market evolution: Computer parts (CN 84733080) — 2015–2025

Introduction

This report examines the evolution of EU extra-EU trade in parts and accessories of automatic data-processing machines (excluding electronic assemblies) over the 2015–2025 period. Covering a broad residual category under CN code 84733080, this product group includes mechanical and non-electronic components used in computers and related machines (heading 8471). The EU has historically been a net importer in this segment, and the decade under review saw significant structural changes: a widening trade deficit, a dramatic geographic reorientation of suppliers, and declining EU export volumes — all set against a backdrop of rising unit prices and geopolitical disruptions.

1. A Growing Deficit Fueled by Price Increases and Volume Divergence

EU import values climbed steadily while volumes stagnated

Over the 2015–2025 period, EU imports of CN 84733080 rose from €3.04 billion to €3.89 billion (+28.2%). However, this increase was not driven by volume growth: import quantities actually fell from 117,137 tonnes to 101,195 tonnes (−13.6%). Instead, unit import prices surged from approximately €25,930 per tonne to €38,469 per tonne (+48.4%), indicating that the EU was paying substantially more per unit of imported product.

EU exports declined sharply in volume despite relatively stable values

On the export side, the EU shipped €1.92 billion worth of these parts in 2015 and €1.88 billion in 2025 (−2.1%). However, this masks a dramatic volume collapse: export quantities fell from 24,761 tonnes to 14,129 tonnes (−42.9%). The offset came from a 71.6% increase in export unit prices (from €77,352 to €132,721 per tonne), suggesting the EU shifted toward exporting higher-value-added or more specialised components.

The trade deficit nearly doubled

As a result of import growth and export stagnation, the EU's trade deficit in this product widened from −€1.12 billion in 2015 to −€2.02 billion in 2025 (−79.9%). The deficit was at its narrowest in 2020 (−€614 million), likely reflecting the COVID-19 disruption to global supply chains, before expanding sharply in 2021–2022 amid the post-pandemic demand recovery and supply-chain bottlenecks.

EU net import reliance ranged from a low of 37.7% to a high of 75.1% during the period, settling at 56.2% in 2025. This moderate decline from 60.3% in 2015 does not indicate improved self-sufficiency so much as a relative shift in the composition of trade flows.

2. A Dramatic Geographic Reorientation of Supply Chains

China remained the dominant supplier, but its share fluctuated

China was by far the EU's largest source of imports throughout the period, growing from €1.54 billion to €1.91 billion (+24.3%). However, its peak came in 2022 at €2.43 billion, after which imports from China declined, suggesting some diversification away from Chinese supply. China's share of extra-EU imports, while still dominant, was being gradually eroded by rising competitors in East and Southeast Asia.

Taiwan and Vietnam emerged as major alternative suppliers

The most striking development was the surge of Taiwan (from €232 million to €725 million, +212.4%) and Vietnam (from €53 million to €271 million, +407.7%) as import sources. Taiwan peaked at €1.14 billion in 2022 before moderating. Vietnam's growth was near-continuous. Mexico also grew rapidly (+354.4%, from €30 million to €134 million). These trends are consistent with the broader "China+1" diversification strategy adopted by global electronics manufacturers.

Traditional Western partners saw steep declines

In contrast, imports from the United Kingdom fell by 78.5% (from €289 million to €62 million), likely reflecting the impact of Brexit and the re-routing of supply chains. Imports from the United States also dropped significantly (−59.5%, from €480 million to €194 million), and Hong Kong declined by 62.7%.

Import concentration remained moderate but shifted structurally

The Herfindahl-Hirschman Index (HHI) for import concentration by value was 2,988 in 2015 and 2,932 in 2025 (−1.9%), indicating a moderately concentrated but slightly diversifying import base. The HHI peaked at 4,659 around 2019–2020, suggesting a temporary period of greater reliance on fewer suppliers (likely China during the pandemic). Export-side concentration was lower (HHI of 783 in 2025) and declining (−18.8%), reflecting a broader diversification of EU export destinations.

EU exports to Russia collapsed entirely under sanctions

Among export destinations, the most dramatic change was the near-complete cessation of exports to Russia — from €31 million in 2015 to just €562 in 2025 (−100%). This reflects EU sanctions imposed following Russia's invasion of Ukraine in 2022. Conversely, the United States grew to become the EU's top export market (from €170 million to €326 million, +91.3%), and exports to the United Arab Emirates also expanded (+80.4%).

3. Declining EU Export Orientation and Shifting Internal Production Dynamics

The EU's export propensity and trade intensity both fell markedly

Two key vulnerability indicators point to a structural shift in the EU's role in this market:

The export propensity — measuring exports relative to production — fell from 177.3% to 60.2%. This extraordinary decline means that the EU went from exporting far more than it produced domestically (suggesting significant re-export or intra-EU processing activity) to a situation where exports represent only about 60% of production. This may indicate that production grew while export capacity was constrained, or that the EU increasingly served its own downstream demand.

EU domestic production grew strongly in value terms

Indeed, EU production of parts and accessories under this code rose from €6.10 billion to €7.94 billion (+30.1%) in value terms, with a peak of €8.76 billion. This growth in domestic production partially offset the rising import bill, though the EU remained a net importer throughout.

Specialisation remained concentrated in a few Member States

In 2025, export specialisation was highest in the Netherlands (RSCA of 0.58, RCA of 3.75), followed by Czechia (RSCA 0.26) and Denmark (RSCA 0.22). The Netherlands' dominance reflects its role as a major logistics and re-export hub for technology products. Germany, despite being the EU's largest economy, had a revealed comparative disadvantage in this product (RCA 0.81, RSCA −0.10).

Import hubs within the EU shifted notably

Among EU importers, the Netherlands remained the largest (from €722 million to €1.21 billion, +67.0%), while Ireland saw the most dramatic growth (+152.1%, reaching €481 million). Czechia, which was a major importer in 2015 (€597 million), saw imports decline to €324 million (−45.7%), consistent with the reorganisation of electronics assembly and logistics chains in Central Europe.

Supply chain volatility was highest for newer sourcing partners

The coefficient of variation of import values was far higher for newer or smaller suppliers: Mexico (CV 2.84), Vietnam (CV 1.46), and Canada (CV 1.30), compared to China (CV 0.08) and Taiwan (CV 0.13). This indicates that while diversification is underway, the newer supply routes are considerably more volatile, posing potential risks for supply security.

Notable price shocks were detected on the export side in 2022 (Turkey: +61% price shift, China: +64.4% price shift) and in 2019 (Switzerland: +61.8% price shift), likely reflecting component shortages and pandemic-era pricing distortions.

Conclusion

The EU's trade in computer parts (CN 84733080) over 2015–2025 is characterised by three overarching trends. First, the trade deficit nearly doubled, driven not by volume increases but by sharply rising unit prices on both the import and export sides, reflecting a global shift toward higher-value components. Second, the geographic composition of imports underwent a profound transformation: while China remained dominant, Taiwan, Vietnam, and Mexico emerged as fast-growing alternatives, while traditional partners like the UK and US saw steep declines — a pattern consistent with global supply chain diversification and the post-Brexit reconfiguration. Third, the EU's export orientation declined significantly, with export volumes nearly halved even as domestic production grew by 30%, suggesting a reorientation of the EU's role from a re-export platform toward serving its own downstream industries. The key risks going forward include the volatility of newer supply routes, concentration of specialisation in a few Member states, and the persistent structural dependence on Asian suppliers for this critical product category.
