Market evolution: Ignition and starting equipment (CN 8511) — 2015–2025

Introduction

This report analyses the evolution of EU external trade in products classified under customs heading CN 8511, which covers electrical ignition and starting equipment for internal combustion engines — including sparking plugs, ignition coils, starter motors, generators, and their parts. The period 2015–2025 was marked by the COVID-19 pandemic, the EU–UK post-Brexit trade reconfiguration, sanctions against Russia, and the accelerating transition toward electric vehicles. Despite these headwinds, the EU's trade in this product category proved remarkably resilient in value terms, even as physical volumes contracted. Three overarching dynamics stand out: a structural shift from a trade deficit to a surplus, a significant geopolitical reshuffling of trade partners, and a pronounced move toward higher-value, lower-volume production and trade.

1. From trade deficit to surplus: the EU's improving competitive position

The trade balance reversed over the decade

In 2015, the EU ran a trade deficit of approximately €137 million in CN 8511 products with the rest of the world. By 2025, this had turned into a surplus of €126 million — a swing of nearly €264 million. The trade balance reached its worst point around 2018–2019 (deficit of roughly €216 million) before improving sharply.

Exports grew considerably faster than imports in value terms, narrowing and eventually closing the gap. The net import reliance indicator confirms this: it moved from −0.45% in 2015 to −1.01% in 2025, meaning the EU shifted from near-balance to being a modest net exporter.

Volumes fell even as values soared

A striking feature of the decade is the divergence between physical volumes and trade values:

EU export volumes declined only modestly (−4.8%), but export unit values rose by nearly 49%, propelling total export value upward. Import volumes fell more steeply (−13.9%), while import prices also rose but at a slower pace (+45.0%). This price gap — EU exports command significantly higher unit values than imports — reflects a product mix oriented toward higher-specification, higher-margin components.

The EU became more export-oriented

The export propensity — the share of domestic production that is exported — rose from 19.1% to 22.7% (+18.8%). Similarly, trade intensity increased from 31.8% to 36.5% (+14.6%). These figures indicate that the EU's ignition and starting equipment industry became more deeply integrated into global markets, with a growing outward orientation.

2. Geopolitical realignment of trade partners

China emerged as the EU's dominant import source — and a fast-growing export market

The most dramatic shift on the import side was the rise of China. EU imports from China surged from €330 million to €613 million (+85.9%), making China the single largest import source by 2025 — overtaking Japan. Meanwhile, on the export side, EU exports to China grew from €167 million to €443 million (+166.0%), the fastest growth among all major partners. China thus became both the EU's largest supplier and its fourth-largest customer for these products.

The UK's role diminished sharply after Brexit

The United Kingdom experienced the most dramatic decline among major partners. As an import source, EU imports from the UK fell from €124 million to €66 million (−46.5%). As an export destination, the decline was more moderate but still significant: from €348 million to €280 million (−19.5%). The volatility data confirm that UK–EU trade in this category became highly unstable, with a coefficient of variation (CV) of 0.654 for imports — the second-highest among all partners. This likely reflects the disruption of integrated automotive supply chains following Brexit.

Russia collapsed as an export destination following sanctions

EU exports to the Russian Federation fell from €105 million to just €12 million (−88.8%), with the most acute drop occurring around 2024. This constitutes one of the most significant supply shocks detected in the dataset, with a shift magnitude of −98.7% in 2024 and an abnormality score of 3.3. At its peak, Russia represented roughly 6% of EU export value in this category. The near-total collapse is consistent with EU sanctions regimes restricting exports of automotive and industrial components.

Mexico declined as an import source but grew as an export market

Imports from Mexico fell from €74 million to €27 million (−63.3%), reflecting the high volatility of this trade route (CV of 0.572). In contrast, EU exports to Mexico more than doubled, from €52 million to €112 million (+115.7%), suggesting that Mexico's role shifted from being a supplier of components to the EU to becoming a market for EU-manufactured equipment — possibly linked to the nearshoring of automotive assembly in Mexico.

The EU import landscape became slightly more diversified

The Herfindahl-Hirschman Index (HHI) for import concentration by value declined from 1,767 to 1,652 (−6.5%), indicating a modest reduction in supplier concentration. However, by volume the import HHI rose sharply from 1,757 to 2,940 (+67.3%), suggesting that physical import flows became more concentrated even as the value distribution diversified — a pattern consistent with a small number of high-volume, lower-cost suppliers (notably China) capturing growing share by mass while more partners contribute to value.

3. Upgrading the product mix: higher value, lower volumes

EU production volumes shrank while production values surged

The most telling indicator of structural change is the divergence in EU production data. Domestic production quantity fell from 642,479 tonnes to 468,058 tonnes (−27.1%), while production value rose from €6.08 billion to €11.18 billion (+83.7%).

This implies that the average value per tonne of EU production more than doubled over the decade. The most likely explanation is a combination of (a) the shift toward higher-value product segments such as advanced ignition systems and integrated starter-generators, (b) the exit or contraction of lower-value, commodity-grade production, and (c) general inflationary pressures in the automotive supply chain.

Sparking plugs exemplify the value-over-volume shift

The sub-product data reveal that the shift is not uniform across segments. Sparking plugs (CN 851110) provide the clearest example:

EU export volumes of sparking plugs fell by over a quarter, yet export values rose by nearly 70%. The unit price more than doubled, from roughly €36,000/t to over €84,000/t. This strongly suggests that EU manufacturers moved upmarket — producing fewer but more specialised, higher-specification plugs (e.g., iridium-tipped, long-life designs for modern engines) — while cheaper, standard plugs increasingly came from low-cost origins.

Starter motors and generators remain the largest segments

By value, the two largest import sub-categories in 2025 were starter motors and dual-purpose starter-generators (CN 851140) at €688 million and generators (CN 851150) at €465 million. On the export side, generators led at €812 million, followed by sparking plugs at €633 million and starter motors at €510 million. The EU thus runs a clear surplus in generators (exporting €812M vs importing €465M) but a deficit in starter motors (importing €688M vs exporting €510M), reflecting the different competitive positions across sub-segments.

Central and Eastern European members gained importance

Within the EU, the most specialised producers in 2025 were Hungary (RSCA of 0.61, RCA of 4.08), Slovenia (RSCA 0.57, RCA 3.68), and Poland (RSCA 0.26, RCA 1.72). Poland's import value grew by 217% (from €87M to €275M) and its export value by 154% (from €65M to €165M), reflecting the country's deepening role in European automotive supply chains. Germany remained the dominant exporter by far, accounting for €1.32 billion in 2025 (+53.9%), well over half of total EU exports. Meanwhile, Hungary's export share declined from €118M to €51M (−56.8%), suggesting a reorientation of its role from direct exporter to an integrated production hub within larger EU supply networks.

Conclusion

Over the 2015–2025 period, the EU's trade in CN 8511 products underwent a fundamental transformation. The bloc shifted from being a net importer to a net exporter, with export values growing nearly 42% despite a modest decline in physical volumes. This performance was driven by a steep increase in unit values — reflecting a product mix that moved decisively toward higher-specification, higher-margin components. Geopolitically, the trade landscape was reshaped by the rise of China (both as supplier and customer), the post-Brexit decline of UK–EU trade, the near-total collapse of exports to Russia following sanctions, and the growing importance of the United States and emerging markets such as Mexico and Brazil. Within the EU, production concentrated in Germany for high-value exports while Central and Eastern European members — particularly Poland and Hungary — expanded their roles as manufacturing and import hubs. Looking ahead, the accelerating transition to electric vehicles poses a structural challenge to this industry, as battery-electric powertrains do not require traditional sparking plugs, ignition coils, or many of the components covered by CN 8511. The observed shift toward higher-value, specialised products may partly reflect the industry's early adaptation to this transition, repositioning around the remaining ICE fleet, hybrid applications, and export markets where ICE vehicles will persist longer.
