Market evolution: High voltage electrical apparatus (CN 853590) — 2015–2025

Introduction

This report examines the evolution of EU trade in CN 853590 — Electrical apparatus for switching or protecting electrical circuits, for a voltage > 1 000 V, a residual subheading within heading 8535 that covers a wide range of high-voltage switching, protection and connection equipment (excluding fuses, automatic circuit breakers, isolating switches, lightning arresters and surge suppressors). This product category is strategically important for the energy transition, grid modernisation and industrial electrification. The analysis covers the period 2015–2025 and draws on EU-27 extra-EU trade data reported in value (EUR), quantity (net mass in tonnes) and unit price (EUR/t), as well as production and specialisation indicators.

1. A Resilient Export Sector Underpinned by a Widening Trade Surplus

1.1 EU exports nearly reached €1.6 billion by 2025

Over the 2015–2025 period, EU extra-EU exports of CN 853590 grew from €1.07 billion to €1.59 billion, an increase of 47.9%. Growth was uneven: exports dipped to a trough of approximately €824 million in 2020 before staging a strong recovery. By 2025, both the value and quantity of exports reached their highest levels in the entire series (36,278 tonnes).

1.2 Unit prices rose significantly, signalling a shift toward higher-value products

While export volumes grew by 17.1%, the increase in export value (+47.9%) was primarily driven by a 26.2% rise in unit prices — from €34,684/t in 2015 to €43,786/t in 2025. This pattern is consistent with a product mix shifting towards more technologically sophisticated or customised high-voltage apparatus, as well as with general inflationary pressures and increased raw-material costs (notably copper and steel) in the post-pandemic period.

1.3 The EU maintained a structural trade surplus exceeding €1 billion

The trade balance remained strongly positive throughout the period, widening from €917 million in 2015 to €1.18 billion in 2025 (+28.7%). At its narrowest, in 2020, the surplus stood at €634 million — reflecting the sharper impact of COVID-19 on export markets than on imports. The EU's net import reliance remained persistently negative (ranging from −83% to −870%), confirming the bloc's role as a consistent net exporter in this product category.

2. A Rapidly Diversifying Import Landscape Led by China and Emerging Suppliers

2.1 Import growth (+159%) far outpaced export growth (+48%)

Despite the EU's structural surplus, imports grew much more rapidly, rising from €157 million to €408 million (+159.4%) over the period. Import volumes more than doubled (+105.4%, from 5,778 to 11,868 tonnes), while import prices also rose by 26.3% to €34,364/t. This acceleration signals growing demand within the EU for high-voltage apparatus sourced from third countries, likely driven by grid expansion, renewable energy integration and the electrification of industry and transport.

2.2 China and India emerged as the fastest-growing import suppliers

The geographic profile of EU imports shifted dramatically. The table below summarises the evolution of the top seven import partners by value:

China's import value grew nearly fivefold, making it the largest single import origin by 2025. India and South Korea, starting from very low bases, recorded the most dramatic relative increases (+1,546% and +2,986% respectively). Switzerland remained a major supplier — likely reflecting both genuine Swiss production (e.g., ABB) and re-export flows through Swiss trading hubs. The United Kingdom, by contrast, saw only marginal growth (+5.1%), suggesting that post-Brexit trade arrangements had a stabilising effect on flows.

2.3 Import concentration declined, reflecting broader sourcing strategies

The Herfindahl-Hirschman Index (HHI) for import value fell from 2,007 to 1,768 (−11.9%), indicating that the EU's import supply base became less concentrated and more diversified over the decade. This diversification is a positive sign for supply-chain resilience. However, it is worth noting that import concentration by volume moved in the opposite direction (HHI rising from 1,827 to 2,377, +30.1%), suggesting that the growth in physical import volumes was channelled through a smaller number of high-volume corridors — most likely China.

2.4 Import volatility was high for emerging Asian suppliers

The coefficient of variation of import values reveals considerable instability for newer supply relationships:

South Korea and India, despite their rapid growth, exhibited very high year-to-year volatility, indicating that these are still developing trade relationships subject to large order-specific effects. By contrast, imports from the United States and Switzerland were far more stable, suggesting deeper and more institutionalised supply chains.

3. European Production Scaling Up and Specialisation Deepening in Central and Northern Europe

3.1 EU domestic production more than doubled in both volume and value

According to production data, EU production of CN 853590 grew from approximately 50.6 million items (€772 million) in 2015 to an estimated 180 million items (€1.94 billion) by 2025 — increases of +256% and +151% respectively. This pace of expansion significantly exceeded both export and import growth, pointing to a surge in intra-EU demand, most likely linked to the massive acceleration of grid investments, renewable energy deployment and industrial electrification driven by the European Green Deal and REPowerEU policy frameworks.

3.2 Central and Northern European Member States emerged as specialised exporters

The specialisation analysis for 2025 reveals a clear geographic pattern of competitive advantage:

Sweden stands out with the highest RSCA (0.59) and the most dramatic export growth: Swedish extra-EU exports surged from €25 million in 2015 to €248 million in 2025 (+881%). Poland (+736%) and Czechia (+1,021%) also recorded explosive growth from low bases, reflecting the successful integration of Central European manufacturing into the global high-voltage equipment supply chain. At the other end of the spectrum, Ireland (RSCA −0.94), Portugal (−0.90) and Greece (−0.83) remained heavily import-dependent with virtually no export specialisation in this product.

3.3 Germany remained the dominant exporter but its relative weight was eroding

Germany continued to be the EU's largest exporter by far, with extra-EU exports of €843 million in 2025 (up 14.0% from €740 million in 2015). However, Germany's share of total EU exports declined as Sweden, Austria (€115 million, +149%), Poland and Czechia captured growing shares. Germany also remained the EU's largest importer (€136 million, +158%), reflecting its role as a central hub for high-voltage equipment within the European value chain — importing components or finished goods that are either consumed domestically or re-exported after further processing.

3.4 Export concentration remained low and stable, supporting resilience

The export-side HHI for value was essentially flat (752 → 761, +1.1%), indicating that the EU's export market remained well-diversified across partners. This contrasts with the import side and reflects the EU's broad network of trade relationships for high-voltage equipment, spanning the Middle East (Saudi Arabia), Asia (China, India), the Americas (United States, Brazil) and neighbouring markets (United Kingdom, Norway, Switzerland). The trade intensity rose from 65% to 78% and export propensity from 61% to 74%, indicating that the EU's high-voltage apparatus sector became progressively more open and globally oriented over the decade.

Conclusion

The EU's trade in high-voltage electrical apparatus (CN 853590) over 2015–2025 tells a story of structural strength combined with evolving competitive dynamics. The bloc maintained a large and growing trade surplus, with exports reaching €1.59 billion by 2025, supported by rising unit prices that suggest a move up the value chain. Domestic production more than doubled, driven by surging demand linked to energy transition investments.

At the same time, imports grew nearly three times faster than exports (+159% vs. +48%), led by a dramatic increase in Chinese, Indian and South Korean supply. While the EU's import base became more diversified by value (HHI declining), the concentration of physical volumes through a smaller number of corridors — principally China — warrants attention from a supply-chain resilience standpoint. Central and Eastern European Member States (Poland, Czechia) and Nordic countries (Sweden) emerged as increasingly specialised and competitive exporters, gradually eroding the formerly overwhelming dominance of Germany. Overall, the sector appears well-positioned for continued growth, but policymakers should monitor the accelerating import penetration from Asia, particularly in the context of the EU's strategic autonomy objectives.
