Market evolution: Solid-state drives (CN 84717098) — 2015–2025

Introduction

CN 84717098 covers storage units for automatic data-processing machines excluding disk, magnetic tape, and central storage units — a residual category that, in practice, overwhelmingly captures solid-state drives (SSDs) and flash-based storage. Over the decade 2015–2025, the EU's external trade in this product category has been reshaped by three intersecting forces: the technological transition from mechanical hard drives to high-capacity NVMe SSDs, a sweeping reconfiguration of global semiconductor supply chains, and a deepening structural reliance on imports. EU import values nearly quintupled while mass volumes barely moved, revealing a market where the unit value of each kilogram traded has soared. This report examines these dynamics across three themes: the price-driven value explosion, the geographic diversification of trade partners, and the EU's growing import dependency alongside declining domestic production.

1. The price-driven value explosion: how the SSD revolution reshaped EU trade flows

The value of EU imports grew fivefold while traded mass remained nearly flat

Between 2015 and 2025, the total value of EU imports of CN 84717098 rose from €1.08 billion to €4.66 billion (+332.6%), while the corresponding mass volume barely moved — from 3,087 tonnes to 3,297 tonnes (+6.8%) (General Overview). This extraordinary divergence implies that the average import price per tonne quadrupled, rising from €348,573/t to €1,412,208/t (+305.1%).

The supplementary unit data confirms the story from a different angle: the EU imported roughly twice as many individual units in 2025 as in 2015 (+105.4%), yet the value per piece more than doubled (+110.6%). This is consistent with the industry-wide shift from smaller-capacity SATA SSDs toward larger-capacity NVMe drives used in data centres, laptops, and enterprise applications — each unit is both heavier and far more expensive than its predecessors.

EU exports followed a similar trajectory, though from a smaller base

EU exports grew even faster in percentage terms, rising from €267 million to €1.68 billion (+529.0%). Export mass roughly doubled (from 905 to 1,866 tonnes), while the export price per tonne tripled from €294,202/t to €900,250/t (+206.0%). The number of pieces exported rose from 2.18 million to 5.64 million (+158.5%), and the price per piece climbed from €122.53 to €298.17 (+143.3%) (General Overview).

The trade deficit widened substantially

Despite the faster growth rate of exports, the absolute trade deficit in value terms deepened from −€809 million to −€2.98 billion (−267.8%). The EU remains a net importer by a wide margin, and the faster-rising import prices per unit have amplified the deficit even as import volumes have been relatively stable in mass terms (General Overview).

2. Geographic reshuffling: new supply hubs emerge and Central Europe becomes an assembly powerhouse

Asian suppliers consolidated their dominance while new entrants surged

The top import origins in 2025 — South Korea (€878M), China (€846M), Taiwan (€603M), and Malaysia (€554M) — together accounted for the bulk of EU SSD imports. What is striking is the evolution of these partners over the decade (top partners by value):

Two dynamics stand out. First, Malaysia and Mexico — both hosts to major semiconductor assembly, test, and packaging (ATP) facilities — went from negligible suppliers to among the EU's top five sources, with growth rates exceeding 6,000%. This reflects the global industry's deliberate diversification of final-stage manufacturing away from concentration in a small number of sites, accelerated by pandemic-era supply chain disruptions and geopolitical risk calculations. Second, United Kingdom imports collapsed by 79.3%, almost certainly a consequence of Brexit, which introduced customs friction and regulatory divergence for goods moving between the UK and the EU.

Import concentration halved as supply sources multiplied

The Herfindahl-Hirschman Index (HHI) for EU imports by value fell from 2,479 to 1,272 (−48.7%), moving from a moderately concentrated market to one that is significantly more diversified (concentration HHI). The HHI for exports also declined, from 1,412 to 973 (−31.1%). The drop in import concentration is particularly notable: while South Korea, China, and Taiwan remain dominant, the emergence of Malaysia, Mexico, and to some extent Vietnam has meaningfully reduced the EU's dependence on any single source.

Czechia, Hungary, and Poland became the EU's SSD assembly and logistics hubs

Within the EU, a dramatic shift occurred in which member states handle SSD trade. Czechia went from a marginal player (€30M imports, €2.4M exports in 2015) to the EU's top exporter (€735M) and third-largest importer (€847M) by 2025. Similarly, Poland (imports from €12M to €663M) and Hungary (imports from €12M to €548M, exports from €2.1M to €70.4M) saw explosive growth (top reporters by value).

These Central European countries likely serve as the final assembly, configuration, and distribution points for global SSD brands that ship components from Asia for integration into finished systems (servers, laptops, enterprise storage arrays). The pattern — high imports and rapidly rising exports from the same countries — is characteristic of processing-for-re-export activity. Germany and the Netherlands remain the largest absolute importers, reflecting their roles as Europe's primary logistics gateways.

The EU's export specialisation concentrated in a handful of member states

Ireland stands out with a revealed symmetric comparative advantage (RSCA) of 0.88 and an RCA of 16.13 — by far the highest in the EU — reflecting the presence of major US technology firms' European operations there. Czechia (RSCA 0.46, RCA 2.70) and Slovakia (RSCA 0.28) also show meaningful specialisation (most specialised reporters). At the other end, Malta, Portugal, and Cyprus show negligible specialisation in this product.

3. Deepening import dependency, declining production, and episodic supply shocks

EU domestic production of SSD storage units has contracted sharply

Available production data shows a worrying trend: EU production of storage units (PRODCOM 26.20.21.00, which maps exactly to this CN code) fell from 13.96 million units (€4.26 billion) in 2015 to 8.00 million units (€1.80 billion) in 2025 — declines of 42.7% by volume and 57.8% by value (production volumes). This contraction, occurring simultaneously with surging import values, underscores the EU's shrinking role as a manufacturer in this segment. The production value decline was steeper than the volume decline, indicating that EU-made units have also shifted toward different product mixes or face margin compression.

Net import reliance has risen and become more volatile

The EU's net import reliance increased from 61.1% in 2015 to 72.6% in 2025 (+18.8 percentage points), but the trajectory was far from linear — it reached as high as 89.5% in an intermediate year before partially recovering. This pattern suggests that while the EU has managed to grow its exports and partially offset rising import needs, the structural gap between domestic consumption and domestic production continues to widen. The trade intensity ratio also rose from 94.0% to 116.6%, meaning total SSD trade (imports + exports) now significantly exceeds the EU's own GDP-weighted market size — a sign of the EU's deep integration into global SSD logistics chains, including re-export activities.

Price shocks have periodically disrupted the market

The supply shock analysis reveals three notable price shock events during the period:

The 2022 Korean shock was by far the most severe (abnormality score of 1,053.7), coinciding with the global NAND flash memory price cycle and post-COVID demand surge. Given that South Korea was the EU's single largest SSD import source by value, the +173.9% price jump had outsized effects on total import costs. The 2020 Malaysian shock may reflect pandemic-era supply disruptions in Southeast Asian ATP facilities, while the 2018 Chinese shock likely relates to the earlier NAND supply squeeze and escalating US-China trade tensions that rippled through global semiconductor markets.

Across partners, Vietnam (coefficient of variation 1.67) and Türkiye (CV 1.98) showed the highest import volatility, while China (CV 0.22) was the most stable import source — consistent with its role as a long-established, large-scale supplier (volatility bars).

Conclusion

The EU's trade in SSDs (CN 84717098) over 2015–2025 tells a story of a market transformed by technology and globalisation. The headline figures — import values up 333%, export values up 529% — mask what is arguably the most important underlying dynamic: the traded mass barely changed while prices per unit of weight quadrupled, reflecting the industry's migration to higher-capacity, higher-value solid-state storage. Geographically, the EU's supply base has diversified significantly, with Malaysia and Mexico emerging as major new sources alongside the established Asian producers, while Central European member states — Czechia, Poland, Hungary — have become critical nodes in the SSD value chain as assembly and distribution hubs. Yet this integration comes with vulnerabilities: domestic production has been cut nearly in half, net import reliance has climbed above 70%, and the market has been subject to episodic but severe price shocks originating from concentrated supply chains in East and Southeast Asia. The EU's strategic challenge going forward will be to balance the efficiency gains of its deeply globalised SSD supply chains against the resilience risks that such dependency entails.
