Market evolution: Electrical connector parts (CN 853890) — 2015–2025

Introduction

This report examines the EU's external trade in CN 853890 — a residual subheading covering parts for electrical switching, protection and connection apparatus (headings 8535–8537), excluding enclosures and bases. The product sits at the heart of Europe's electrical equipment supply chain, serving industries from power distribution to semiconductor manufacturing. Over the 2015–2025 period, the EU maintained a large and persistent trade surplus in this product, yet the underlying dynamics shifted markedly: imports nearly doubled in value, unit prices climbed steeply, and the geographic composition of trade underwent significant restructuring. The analysis below draws on trade-flow data, partner-level breakdowns, domestic production figures, and shock-detection indicators.

1. A widening value gap masks diverging volume trajectories

1.1 Exports grew in value while volumes stagnated

EU exports of CN 853890 rose from €4.30 billion in 2015 to €5.96 billion in 2025, a cumulative increase of 38.4%. Over the same period, exported tonnage barely moved — from 108,652 t to 113,543 t (+4.5%). The entire gap was filled by rising unit values, which climbed from €39,598/t to €52,457/t (+32.5%). This pattern suggests that EU producers moved up the value chain, exporting higher-value-added assemblies rather than simply shipping greater physical volumes.

1.2 Imports surged in both volume and value

By contrast, imports accelerated far more aggressively. Import value nearly doubled from €1.67 billion to €3.13 billion (+87.9%), while volumes jumped from 53,858 t to 93,353 t (+73.3%). Unit import prices rose more modestly (+8.4%), reaching €33,538/t in 2025 — still well below the EU's export unit price of €52,457/t. The gap between export and import unit values (roughly €19,000/t) is a strong signal that the EU specialises in higher-specification parts while importing more standardised components.

1.3 The surplus narrowed but endured

The EU remained a net exporter throughout, with the trade balance ranging between €2.21 billion (2022) and €3.31 billion (2017). By 2025 it stood at €2.83 billion, +7.2% above the 2015 level. However, the net import reliance ratio improved from −40.1% to −26.1%, indicating that the EU's relative self-sufficiency eroded: imports are growing faster relative to domestic production than exports are. The ratio's worst year was 2021 (−52.7%), reflecting the post-COVID import surge.

2. Geographic reorientation: nearshoring partners and China's dual role

2.1 China became the EU's largest import source — and prices spiked

China's share of EU imports in CN 853890 grew from €379 million in 2015 to €1.005 billion in 2025 (+165.1%), making it by far the largest single supplier. China alone accounts for roughly one-third of all EU imports by value. A major price shock in 2022 — with an abnormality score of 739.8 and a unit-price shift of +31.3% — coincided with post-pandemic logistics bottlenecks and energy-cost pass-through. This shock affected 42.4% of import value, underscoring the EU's concentrated exposure to Chinese supply.

2.2 Southern and eastern Mediterranean partners emerged rapidly

Morocco (+244.8%) and Tunisia (+183.7%) registered the fastest import growth among the top seven partners. By 2025 they collectively supplied €358 million of imports, up from just €115 million in 2015. This is consistent with EU nearshoring strategies and the development of integrated electrical-component assembly platforms in the Maghreb, often serving automotive and industrial OEMs. On the export side, Morocco (+79.8% to €385 M) and Tunisia (+73.6% to €281 M) also absorbed significantly more EU-made parts, pointing to two-way integration rather than simple offshoring.

2.3 The UK post-Brexit: a dramatic export reorientation

The most striking bilateral shift involved the United Kingdom. EU exports to the UK surged from €240 million to €858 million (+257.4%), with a peak of €895 million in 2024. This likely reflects post-Brexit customs formalities that created a preference for sourcing finished parts from the EU rather than relying on previously frictionless intra-EU supply chains. Import flows from the UK, by contrast, remained essentially flat (−4.0%), and the coefficient of variation of UK import flows reached 1.58 — the highest among all major partners — reflecting erratic year-to-year volumes during the transition period.

2.4 The US remained the top extra-EU export destination

EU exports to the United States grew from €528 million to €910 million (+72.2%), making the US the largest single export market in 2025. Together with the UK, these two Anglo-Saxon markets absorbed roughly €1.77 billion, or nearly 30% of all EU exports. The export HHI stayed broadly stable (769 → 811), suggesting that while the top partners changed, the overall degree of export-market diversification did not deteriorate significantly.

2.5 Central and eastern European members drove intra-EU specialisation

Within the EU, revealed comparative advantage data for 2025 shows that Bulgaria (RSCA 0.76), Romania (0.63), Hungary (0.33), and Czechia (0.29) are the most specialised EU producers. These countries' strong positions in automotive wiring harnesses and industrial switching components explain their high product-specific export shares relative to their overall trade. Among large economies, Germany dominated both exports (€2.25 billion, 2025) and imports (€742 million), reflecting its role as the EU's central hub for electrical equipment manufacturing.

3. Rising prices, concentration risks, and the 2022 shock

3.1 Unit values diverged between segments

The product heading CN 853890 bundles four sub-categories. The dominant one — 85389099 (general parts, excl. electronic assemblies and wafer-prober parts) — accounted for 73% of import value and 81% of export value in 2025. Its export unit price rose from €29,311/t (2015) to €41,514/t (2025). The much smaller but high-value sub-segment 85389091 (electronic assemblies for switching/protecting apparatus) commanded the highest prices: €234,554/t for exports in 2025, up from €185,622/t in 2015. Import prices in this sub-segment reached €130,324/t — still well below the export price, confirming the EU's position in higher-specification assemblies.

The wafer-prober sub-segments (85389019 and 85389011) show a striking inversion: the EU is a net importer at high unit prices, reflecting its reliance on specialised semiconductor-manufacturing components — a pattern consistent with Europe's broader dependency on imported chipmaking equipment parts.

3.2 Import concentration intensified while export markets remained diversified

The import HHI by value rose from 1,140 to 1,437 (+26.1%), crossing above the 1,250 threshold often considered the boundary of moderate concentration. The import volume HHI climbed even more steeply (+68.5% to 2,570), indicating that physical supply is more geographically concentrated than the value figures suggest. China's dominant position is the primary driver. The export HHI remained below 1,000 throughout, reflecting a healthier diversification of destination markets.

3.3 The 2022 episode revealed compounded vulnerabilities

The year 2022 stands out as the most disruptive in the dataset. Three shock events were identified:

• China import price shock: abnormality 739.8, +31.3% unit-price shift, affecting 42.4% of import value.
• India export price shock: abnormality 38.9, +62.5% unit-price shift, affecting 4.9% of export value.
• Switzerland import price shock (actually 2020): abnormality 12.3, −32.1% unit-price shift.

The China shock was by far the largest in absolute terms and coincided with a temporary dip in the trade balance to its lowest point (€2.21 billion). The import volume from China dropped from a peak of 98,829 t (2020) to 77,625 t (2022) before partially recovering, suggesting a combination of supply disruptions and demand destruction. Meanwhile, EU domestic production value soared from €4.94 billion (2015) to €13.19 billion (2025) (+167%), peaking at €16.1 billion in 2023. This production boom — partly driven by reshoring incentives and the EU's electrification agenda — helped offset import dependency but could not fully substitute for the specialised components sourced from China and other Asian suppliers.

3.4 Trade intensity remained high, confirming the sector's openness

The trade intensity ratio hovered between 47% and 57% throughout the period, settling at 54.2% in 2025. The export propensity — the share of domestic production exported outside the EU — declined slightly from 45.1% to 43.7%, suggesting that a growing share of output is absorbed internally as EU electrification projects (grid upgrades, EV infrastructure, renewable-energy connections) expand domestic demand.

Conclusion

The EU's trade in CN 853890 over 2015–2025 tells the story of a sector that remained structurally competitive — maintaining a multi-billion-euro surplus and rising production — but became increasingly exposed to concentrated import supply. China's role as the dominant external supplier grew dramatically, and the 2022 price shock demonstrated the fragility that comes with that concentration. At the same time, encouraging signs emerged: nearshoring to the Maghreb, stronger UK export demand post-Brexit, and a pronounced upshift in export unit values all point to EU firms consolidating their position in higher-value segments. The critical challenge going forward is managing the tension between the need for cost-effective standardised imports (mainly from China) and the strategic imperative to diversify sourcing — particularly for the semiconductor-adjacent sub-segments where the EU remains a net importer at premium prices.
