Market evolution: Hard disk drives (CN 84717050) — 2015–2025

Introduction

This report examines the evolution of EU trade in hard disk drives (CN 84717050) over the period 2015–2025. The product covers non-optical, non-magneto-optical hard disk storage drives for automatic data-processing machines — a category at the heart of the global storage industry. Over the past decade, this market has undergone a profound structural transformation driven by the rise of solid-state storage (SSDs), shifts in global manufacturing footprints, and geopolitical realignment. EU imports, which reached €5.49 billion in 2015, stood at €4.59 billion in 2025, while trade volumes in both tonnes and units have fallen by roughly two-thirds. Meanwhile, the net import reliance of the EU has climbed from 61% to 73%, and import concentration has more than doubled, raising new vulnerability questions even as total demand contracts.

1. A Market in Structural Decline: Falling Volumes Meet Rising Unit Values

1.1 Trade values have declined modestly despite a collapse in physical volumes

The headline trade figures mask a far more dramatic underlying story. Between 2015 and 2025, EU imports of hard disk drives fell by 16.3% in value (from €5.49 billion to €4.59 billion) and exports by 23.3% (from €1.79 billion to €1.37 billion) — General Overview. These moderate value declines conceal a dramatic fall in physical volumes:

Both import and export volumes have roughly halved to two-thirds over the decade. This is consistent with the secular decline of traditional hard disk drives in the face of SSD adoption in consumer electronics, laptops, and increasingly in enterprise storage.

1.2 Unit values have surged, reflecting a shift toward higher-end products

The partial resilience of trade values in the face of collapsing volumes is explained by a sharp increase in unit prices. Import prices per tonne rose by 140.3% (from €144,606 to €347,531) and per unit by 169.3% (from €75 to €203). Export prices followed a similar trajectory, rising 86.1% per tonne and 43.8% per unit:

This divergence indicates a compositional shift in the remaining market: as SSDs capture the consumer and mid-range segments, surviving HDD demand increasingly concentrates in high-capacity enterprise and data-centre drives, which carry substantially higher unit values. The EU's trade deficit in this product nonetheless narrowed slightly, from –€3.70 billion in 2015 to –€3.22 billion in 2025, an improvement of 13.0%.

1.3 EU domestic production has contracted in parallel

EU production data confirms the broader decline: output fell from approximately 14.0 million units (€4.26 billion) in 2015 to an estimated 8.0 million units (€1.80 billion) in 2025, a drop of 42.7% in volume and 57.8% in value. At its production peak around 2017–2018, EU output exceeded 19 million units and €6 billion in value, suggesting the region once played a significant role in global HDD assembly and testing. The subsequent decline mirrors global consolidation in the HDD industry, where Seagate and Western Digital — the primary remaining manufacturers — have progressively rationalised production footprints.

2. Geographic Realignment: Thailand's Dominance, China's Retreat, and the UK's Disengagement

2.1 Thailand has consolidated its position as the EU's overwhelmingly dominant supplier

The most striking geographic shift in EU HDD imports has been the rise of Thailand. In 2015, Thailand supplied €1.90 billion worth of drives (34.5% of imports). By 2025, this had grown to €2.95 billion — representing 64.3% of total EU imports. Thailand's growth of +55.8% in value stands in sharp contrast to declining volumes overall, suggesting it has captured the lion's share of the remaining high-value enterprise drive market. Thailand hosts major production facilities for both Western Digital and Seategic.

2.2 China and Malaysia have nearly exited as HDD suppliers to the EU

China's role as an EU supplier of HDDs has collapsed by 68.5% in value, from €1.55 billion to €489 million. This decline reflects multiple dynamics: the shift of final assembly and testing out of China toward Southeast Asia (principally Thailand), rising labour costs, and potentially increasing trade tensions. Malaysia's decline has been even more dramatic — a 95.2% drop from €229 million to just €11 million — as Seagate's Penang operations appear to have wound down their HDD production, consistent with global industry consolidation.

2.3 The United Kingdom's trade in HDDs has collapsed on both sides post-Brexit

The UK's bilateral trade in this product provides a clear case study in post-Brexit adjustment. UK imports to the EU fell 83.6% from €377 million to €62 million, and EU exports to the UK fell 77.5% from €629 million to €142 million. Before Brexit, the UK was both a major transit and distribution hub for IT hardware in Europe; the steep declines on both flows suggest either tariff and customs-friction effects, re-routing of trade through EU ports (notably the Netherlands), or both.

2.4 The Netherlands has emerged as the EU's dominant trade hub

Among EU member states, the Netherlands has dramatically strengthened its position. Its imports grew from €1.45 billion to €2.13 billion (+46.3%), while exports surged from €447 million to €820 million (+83.4%). With an RCA of 2.90 and RSCA of 0.49, the Netherlands is by far the most specialised EU member state in this product, reflecting its role as Europe's principal gateway for Asian-manufactured electronics via the Port of Rotterdam and Schiphol Airport. Germany and Czechia, by contrast, have seen significant declines in both import and export activity, consistent with the winding down of assembly operations in Central and Western Europe.

2.5 Russia has been entirely cut off from EU HDD exports

EU exports to Russia fell from €192 million in 2015 to virtually zero by 2025 (–100.0%). This is attributable to the successive rounds of EU sanctions imposed following Russia's invasion of Ukraine in 2022, which restricted the export of dual-use technologies including data-processing equipment. Meanwhile, the United States has grown as both an import source (+115.5% to €436 million) and an export destination (+166.3% to €303 million), reflecting the US's role in enterprise storage systems and re-export flows.

3. Rising Concentration and Deepening Import Dependence

3.1 Import source concentration has more than doubled, creating acute dependency risks

The Herfindahl-Hirschman Index (HHI) for EU imports by partner country surged from 2,194 to 4,442 (+102.4%) over the period. In standard competition analysis, an HHI above 2,500 is considered highly concentrated; at 4,442, the EU's import base for HDDs is now extremely concentrated in the hands of a single supplier — Thailand. This concentration is driven by the industry's oligopolistic structure (only three major manufacturers globally: Seagate, Western Digital, and Toshiba) and the geographic clustering of their production facilities.

Export concentration by value has been more moderate and relatively stable (HHI rising from 1,555 to 1,691), though it fell significantly by volume, suggesting that while fewer export destinations carry larger values, the physical shipments have become more diversified.

3.2 Net import reliance has increased, compounding vulnerability

The EU's net import reliance for hard disk drives rose from 61.1% in 2015 to 72.6% in 2025, peaking at 89.5% in an intermediate year. This deepening dependency is the result of three concurrent trends: declining domestic production, shrinking export capacity, and the continued need for imported drives despite falling overall volumes. Combined with the extreme supplier concentration described above, this creates a situation where the EU is both more dependent on imports and more exposed to disruptions in a single country.

3.3 Trade intensity and export propensity suggest the market is becoming more specialised

The EU's trade intensity rose from 94.0% to 116.6%, while export propensity increased from 79.8% to 192.6%. The latter metric — which relates exports to domestic production — indicates that a growing share of EU-assembled drives are destined for non-EU markets, while fewer remain for internal consumption. This aligns with the geographic specialisation data showing that the Netherlands and Czechia (the two most specialised member states) function largely as re-export and assembly/transshipment platforms for global distribution rather than serving purely domestic demand.

3.4 Supply shocks have emerged, particularly in export price dynamics

The volatility analysis reveals significant shock events in EU HDD trade. The most notable was a price shock in exports to the United States in 2019, with an abnormality score of 16.8 and a year-on-year price shift of +54.7%, affecting flows representing 19.4% of export value. Additional price shocks were detected in exports to Malaysia (+261.6% in 2022) and the United Arab Emirates (+60.8% in 2022). On the import side, volatility has been highest for smaller or declining suppliers — Hong Kong (coefficient of variation 1.73), Tunisia (1.60), and Singapore (1.28) — while the dominant supplier Thailand shows relatively low volatility (CV 0.30), reflecting its stable, large-scale production base.

Conclusion

The EU market for hard disk drives (CN 84717050) has undergone a profound structural transformation between 2015 and 2025. Volumes have declined by roughly two-thirds as solid-state drives progressively displace traditional HDDs across most computing segments. What remains is an increasingly specialised, high-value niche concentrated in enterprise and data-centre applications, where unit prices have more than doubled. Geographically, the market has consolidated sharply around Thailand, which now supplies nearly two-thirds of EU imports by value, while China, Malaysia, and the United Kingdom have receded as trade partners. EU domestic production has contracted substantially, and the Netherlands has emerged as the principal hub for both imports and re-exports. The combined effect of rising import dependence (now at 73%) and extreme supplier concentration (HHI above 4,400) creates a material vulnerability for the EU in a product category that, while declining, remains strategically important for data infrastructure. Monitoring supply-chain resilience in this segment — particularly given the industry's oligopolistic structure and geographic concentration in Southeast Asia — should remain a priority for European trade and industrial policy.
