Market evolution: Static converter parts (CN 85049090) — 2015–2025

Introduction

This report examines the European Union's trade in parts of static converters (customs code 85049090) over the period 2020–2025 — the window for which complete annual data is available. Static converter parts are an essential component of the broader power electronics supply chain, feeding into applications ranging from telecommunications and computing to renewable energy and electric vehicles. The EU's trade in this product category has undergone significant structural changes: import volumes have surged far more rapidly than export volumes, the trade balance has flipped from surplus to deficit, and supplier concentration — especially toward China — has deepened markedly. The following sections analyse these dynamics in detail.

1. A Structural Reversal: The EU Shifts from Net Exporter to Net Importer

The most striking development over the period is the EU's transition from a positive trade balance in static converter parts to a deficit. While both imports and exports grew substantially, the pace of import growth was roughly double that of exports, fundamentally altering the EU's position in this market.

1.1 Import growth far outstripped export growth

Between the first and last years of the available data, EU imports of static converter parts more than doubled in value (+106.8%), rising from €571 million to €1,181 million, and nearly doubled in volume (+86.8%), from 26,218 tonnes to 48,973 tonnes. By contrast, exports grew by 53.0% in value (from €715 million to €1,094 million) and 24.8% in volume (from 15,243 tonnes to 19,023 tonnes).

Notably, the EU's unit export price (€57,488/t in the last year) remains more than double the import price (€24,106/t), suggesting that EU exports are biased toward higher-value or more specialised parts, while imports tend to be more commoditised components.

1.2 The trade balance swung into negative territory

At the start of the period, the EU recorded a trade surplus of €144.3 million. By the final year, this had turned into a deficit of €86.7 million — a swing of approximately −160%. The deficit peaked in an intermediate year at around €133.6 million. This reversal reflects the structural widening of the import–export gap driven by Europe's growing demand for power electronics components, likely linked to the expansion of renewable energy, electric mobility, and data infrastructure.

1.3 The EU remains a significant producer, but production growth lags behind demand

According to PRODCOM production data, the value of EU domestic production rose from €685 million to €1,119 million (+63.2%). While this is substantial growth, it was insufficient to keep pace with the near-doubling of import demand, implying that a growing share of the EU's consumption of these parts is being met from external sources. Net import reliance worsened from −53.9% to −60.2% over the period.

2. China's Dominance and the Rising Concentration of EU Imports

The second major dynamic is the growing dominance of China as a supplier of static converter parts to the EU, accompanied by a marked increase in overall import concentration. This trend carries significant implications for supply-chain resilience.

2.1 China accounts for the bulk of EU imports and their growth

China was already the EU's largest single supplier at the start of the period, with imports valued at €260 million. By the final year, that figure had risen to €679 million — an increase of 161.1%. China's share of total EU imports in the last year stood at approximately 57% by value, and even higher by volume given China's lower unit prices. No other partner comes close: the next-largest suppliers include Switzerland (€50 M), India (€34 M), Taiwan (€33 M), and Thailand (€32 M).

2.2 Import concentration has risen sharply

The Herfindahl-Hirschman Index (HHI) for import value increased from 2,378 to 3,480 (+46.3%), crossing well above the 2,500 threshold that is conventionally considered "highly concentrated." This increase is almost entirely driven by China's expanding share. The HHI for import volume rose even more steeply, from 2,901 to 5,216 (+79.8%), reflecting China's simultaneous gain in both volume and value share.

By contrast, the export-side HHI remained essentially flat (around 1,000), indicating that the EU's export destinations remained well diversified — a sign of resilience on the outward-facing side of the market.

2.3 Price shocks highlight the vulnerability of heavy reliance on a single supplier

Volatility analysis reveals several notable supply-side price shocks. In 2022, Chinese import prices experienced a shock with an abnormality score of 12.4 and a year-on-year shift of +24.1%, affecting imports that represented 84.8% of total EU import value in that year. A second shock was detected in imports from Türkiye in 2023 (abnormality 52.1, shift +57.9%), though its value share was much smaller (2.8%). The volatility profiles of individual partners vary considerably: imports from the UAE and Philippines show the highest coefficients of variation (0.45 and 0.60 respectively), while imports from Switzerland and the UK are the most stable (CVs of 0.19 and 0.17).

3. Uneven Growth Across EU Members and the Emerging Role of Central and Eastern Europe

Behind the aggregate EU figures lies a differentiated picture across member states. Germany remains the dominant player, but several smaller economies — particularly in Central and Northern Europe — have seen disproportionately rapid growth in both imports and exports.

3.1 Germany anchors both sides of EU trade

Germany is by far the largest EU importer and exporter of static converter parts. Its imports rose from €159 million to €213 million (+33.6%), while its exports moved from €324 million to €400 million (+23.4%). Germany accounts for roughly 34% of EU production value and 21% of total EU trade in this product, and it maintains a revealed comparative advantage (RCA) above 1 (1.62), confirming its specialisation.

3.2 Poland and Sweden experienced explosive growth

Among EU members, Poland and Sweden stand out for the magnitude of their trade growth:

Poland's import surge likely reflects the country's rapid industrial integration into European electronics and automotive supply chains, including assembly operations for power electronics. Sweden's export explosion, meanwhile, may be linked to companies such as those in the Nordic power-conversion and industrial-automation sector scaling up their international shipments.

3.3 Specialisation patterns reveal a two-speed Europe

The specialisation analysis for 2025 highlights a clear divide. A handful of member states — notably Estonia (RSCA 0.82), Finland (0.76), Romania (0.68), Slovakia (0.44), and Germany (0.24) — display strong comparative advantages in this product category. These countries combine relatively modest overall trade shares with disproportionately high shares of static converter parts in their export baskets, suggesting the presence of specialised manufacturing clusters.

At the other end of the spectrum, countries such as Croatia, Cyprus, Lithuania, Luxembourg, and Belgium show strong negative RSCA values (ranging from −0.91 to −0.79), indicating that they are net importers with virtually no specialisation. This two-tier structure implies that the EU's capacity to produce and export static converter parts is geographically concentrated in a small number of member states.

Conclusion

Over the period under review, the EU's market for static converter parts has been reshaped by three converging forces: surging demand that outpaced domestic production, an increasing dependence on Chinese imports, and a growing specialisation gap among member states. The trade balance has swung from a €144 million surplus to an €87 million deficit, with imports more than doubling in value. China now accounts for over half of all EU imports by value, and the import-side HHI has risen to levels that signal high concentration and associated vulnerability. At the same time, the EU's export base has remained well diversified across partners, and several member states — including Poland, Sweden, and Finland — have emerged as fast-growing nodes in the value chain. The product's dual PRODCOM mapping (covering both telecom/computing electronic assemblies and other static converter parts) reflects the breadth of downstream applications, from data centres and 5G infrastructure to solar inverters and EV chargers. Sustained demand growth from these end-use sectors is likely to maintain pressure on the EU's import needs unless domestic capacity — currently led by Germany, Finland, Romania, and a few smaller specialised economies — expands more rapidly.
