Market evolution: Automotive starter batteries (CN 850710) — 2015–2025

Introduction

This report analyses the evolution of European Union trade in automotive starter batteries (Combined Nomenclature code 850710) over the decade from 2015 to 2025. The EU has demonstrated a robust performance in this sector, evolving from a position of moderate trade surplus to becoming a more dominant net exporter. The period was characterised by significant overall market expansion, a notable realignment of key trading partners, and periods of price volatility linked to major global economic shocks. This report examines these core dynamics based on the provided trade data.

1. Sustained Market Growth with a Strengthening Net Export Position

The EU's trade in starter batteries expanded significantly in value terms throughout the period. Both exports and imports grew, but exports consistently outpaced imports, leading to a substantial improvement in the EU's trade balance. This section details the scale of this expansion and the EU's solidifying role as a net exporter.

1.1. Strong Export-Led Value Growth

The EU's export value for starter batteries increased by 61.3%, rising from €871 million in 2015 to over €1.41 billion in 2025. While import value also grew robustly by 51.3% (from €492 million to €744 million), the faster pace of exports is the primary driver of the sector's positive performance. The growth was not linear; export value peaked at €1.43 billion in 2023 before a slight correction, indicating a dynamic and expanding market. (Market Overview)

1.2. Expanding Trade Surplus

As a direct result of faster export growth, the EU's trade surplus for CN 850710 widened considerably. The surplus grew by 74.3%, from €379 million in 2015 to €661 million in 2025. It reached its zenith in 2023 at €753 million. This consistent surplus underscores the EU's strong competitive advantage and production capacity in this traditional automotive component.

1.3. Domestic Production Supports Export Capacity

EU production of starter batteries (measured in items) grew by 9.1%, from 92.6 million pieces in 2015 to 101 million in 2025, peaking at 103.3 million in 2024. Production value increased by 18.0% to over €5 billion. This domestic production base was crucial in sustaining the high level of exports and meeting both internal and external demand.

2. Geopolitical Realignment of Key Trading Partners

The decade saw a dramatic reshuffling of the EU's most important trading partners for starter batteries. Traditional relationships were disrupted, leading to a diversification of export destinations and a shift in import sourcing, influenced by geopolitical events, Brexit, and evolving global supply chains.

2.1. Export Diversification Away from Traditional Partners

The United States emerged as the EU's most significant export growth market. Exports to the US surged by 426.4%, from €47.6 million in 2015 to €250.5 million in 2025, making it a top destination. Conversely, exports to China collapsed by 81.3% (from €131 million to €24.5 million), and exports to Russia fell by 86.2% (from €49.3 million to €6.8 million), particularly after 2022. New growth poles include Turkey (+333.2%) and South Africa (+158.3%). (Top Partners by Value)

2.2. Shifts in Import Sourcing

Imports to the EU have become more concentrated in Asia. South Korea remains the largest single supplier, with its share growing from €134 million to €192 million (+43.3%). The most dramatic growth came from Turkey (+232.5% to €93.5 million) and North Macedonia (+222.2% to €65.5 million). A notable decline occurred in imports from the United Kingdom, which fell by 62.9% (from €40.4 million to €15 million), a likely consequence of Brexit-related trade friction. (Top Partners by Value)

2.3. Changing Trade Concentration and Internal Specialisation

While the concentration of import sources (measured by the Herfindahl-Hirschman Index) increased slightly, indicating a modestly more focused import base, export concentration decreased, confirming the diversification of export markets. Within the EU, production is specialised in certain member states. Czechia and Spain show the highest revealed comparative advantage (RCA >2.6), indicating strong export specialisation in this product. (Concentration & Specialisation)

3. Price Dynamics and Supply Chain Volatility

The period was marked by significant price increases and detectable supply shocks, reflecting broader macroeconomic and geopolitical turbulence. Price movements differed between the two main product sub-segments and across different trading relationships.

3.1. Overall Price Inflation with Segment Divergence

Export unit prices (per tonne) increased by 26.2% over the decade, while import prices rose by 11.4%, squeezing import margins. However, a divergence exists between sub-segments. For exports, the premium-priced non-liquid electrolyte segment (85071080) saw its unit price (per piece) soar by 84.8%, far outpacing the 20.9% increase for the standard liquid electrolyte segment (85071020). This suggests either a shift in the export mix towards higher-value products or significant inflation in that niche. (Product Segment Breakdown)

3.2. Identification of Key Supply Shocks

The data reveals several statistically significant price shocks:

• 2022 - South Korea Imports: A price shock with an abnormality of 19.2 and a 17.5% price shift was detected for imports from South Korea in 2022. This aligns with global supply chain disruptions and raw material inflation post-COVID.
• 2023 - United States Exports: A major price shock (abnormality 6.8, +25.6% shift) occurred for exports to the US in 2023, possibly linked to surging demand, tariffs, or logistics costs.
• 2022 - Indonesia Imports: A 63% price shift for imports from Indonesia in 2022, though with a smaller value share, indicates acute cost pressures from that source. (Supply Shocks)

3.3. Volatility in Bilateral Relationships

The coefficient of variation (CV) highlights which trade relationships are most volatile. For exports, flows to China (CV 0.73) and Saudi Arabia (CV 0.73) were highly unstable, reflecting unpredictable demand. On the import side, flows from Turkey (CV 0.50) and the UK (CV 0.43) showed high volatility. In contrast, the relationship with South Korea for imports was relatively stable (CV 0.11). (Volatility)

Conclusion

Over the 2015–2025 period, the EU's market for automotive starter batteries demonstrated resilience and strategic adaptation. The bloc solidified its position as a major net exporter, with export value growth far outstripping that of imports. The most profound change was the geopolitical realignment of trade flows: the US and Turkey became critical growth markets, while exports to China and Russia plummeted, and imports from the UK fell sharply post-Brexit. Price dynamics were marked by broad inflation and notable shocks, particularly during the post-pandemic supply chain crisis of 2022. Despite increased volatility in certain bilateral ties and a rising import dependency on key Asian suppliers like South Korea, the EU's strong internal production base and diversified export portfolio have strengthened its overall trade position in this vital automotive component.
