Market evolution: Bearing parts (CN 848299) — 2015–2025

Introduction

This report examines the trade dynamics of CN 848299 — parts of ball or roller bearings (excluding balls, needles and rollers), n.e.s. — for the European Union over the period 2015–2025. This product category is a residual subheading under heading 8482, covering items such as bearing housings, cages, and other components not elsewhere specified. It is a critical input for automotive, industrial machinery, and wind-energy supply chains.

Over the examined decade, the EU's position in this market has undergone a fundamental transformation. What was once a near-balanced trade profile with a small surplus has become a structurally deficit-ridden segment, with net import reliance swinging from −10.6% in 2015 to +31.9% in 2025. Three main dynamics underpin this evolution: (1) a sharp contraction in export volumes coupled with rising unit values; (2) a surge in import volumes concentrated on Asian suppliers, especially China; and (3) growing vulnerability linked to supplier concentration and recurring supply-side shocks.

1. From surplus to deficit: The structural erosion of the EU's trade position

1.1 The trade balance turned decisively negative after 2018

In 2015, the EU's trade balance for bearing parts stood at +€7.7 million, meaning the bloc was a marginal net exporter. By 2025, this had collapsed to −€300.1 million — a deterioration of nearly 4,000%. The deficit reached its widest point at an estimated −€358.8 million at some point during the period. This is not a cyclical fluctuation but a structural shift: imports grew while exports shrank, and the gap widened year after year.

1.2 Export volumes have nearly halved while import volumes have surged

The most striking feature is the divergence in volumes. EU export quantities fell from 35,479 tonnes to 17,811 tonnes (−49.8%), while import quantities climbed from 75,646 tonnes to 128,718 tonnes (+70.2%). In value terms the picture is similar: exports declined from €445.8 M to €362.2 M (−18.7%) while imports rose from €438.1 M to €662.4 M (+51.2%).

1.3 EU production has contracted modestly

EU production value for bearing parts declined from €632.6 M to €581.6 M (−8.1%), with a peak reaching €1,135.9 M at some point in the period. This moderate contraction in domestic output does not fully explain the trade balance shift on its own; rather, the EU's own demand appears increasingly satisfied by imports while export competitiveness has weakened.

2. The Asian pivot: Rising concentration of imports around China and emerging suppliers

2.1 China has nearly doubled its share of EU bearing-part imports

China is by far the dominant import partner, with import value rising from €164.6 M to €327.3 M (+98.9%). At its peak, Chinese imports reached €369.8 M. This means that nearly half of all extra-EU bearing-part imports now originate from a single country. India also more than doubled its contribution, growing from €35.7 M to €80.5 M (+125.9%), while South Korea (+178.8%) and Taiwan (+36.1%) further reinforced the Asian character of EU imports.

By contrast, Japan (−33.0%) and Ukraine (−48.9%) saw declining exports to the EU, likely reflecting both competitive displacement and geopolitical disruption, respectively.

2.2 Import concentration has risen sharply, while export markets remain diversified

The Herfindahl–Hirschman Index (HHI) for imports by value rose from 1,803 to 2,764 (+53.3%), crossing from the "moderately concentrated" into the "highly concentrated" threshold. The volume-based HHI for imports grew even faster, from 2,684 to 4,752 (+77.1%). This confirms that the EU's import base has become significantly more concentrated, with China absorbing an ever-larger share.

Export HHI remained comparatively stable at around 1,056–1,107 by value, indicating that EU exports continue to serve a relatively diversified set of markets. However, this partly reflects the fact that exports are declining across the board, rather than any deliberate diversification effort.

2.3 Germany remains the EU's hub, but Central and Eastern European members are gaining ground

Among EU reporters, Germany dominates both trade flows: it accounts for the largest share of exports (€190.4 M in 2025, though down 20.5% from 2015) and imports (€176.0 M, +16.8%). However, several Central and Eastern European members have seen their import needs grow dramatically: Poland's imports rose from €20.2 M to €64.3 M (+219.1%), and Romania's from €16.2 M to €49.1 M (+203.4%). Slovakia also recorded strong import growth (+66.8%). This suggests a geographic reorientation of bearing-parts consumption toward CEE manufacturing clusters, particularly in the automotive sector.

Romania and Slovakia also stand out for their export specialisation: Romania's RSCA index is 0.83 (RCA of 10.5) and Slovakia's is 0.67 (RCA of 5.0), far above Germany's more modest RCA of 1.48. This indicates that bearing parts represent a disproportionately important export niche for these economies.

3. Price divergence, supply shocks, and growing vulnerability

3.1 EU export prices have soared while import prices have declined

One of the most consequential dynamics is the divergence in unit prices. EU export unit values rose from €12,563/t to €20,328/t (+61.8%), while import unit values fell from €5,790/t to €5,145/t (−11.1%). This means EU exports are now priced at roughly four times the level of imports.

This pattern is consistent with a classic specialisation dynamic: the EU retains production and export of high-value-added, technically sophisticated bearing parts, while lower-commodity-grade components are increasingly sourced from lower-cost Asian suppliers. However, the simultaneous decline in export volumes suggests that this "moving up the value chain" has not been sufficient to maintain overall market share.

3.2 The 2022 supply chain disruptions triggered notable price shocks

Three significant price shocks were detected around 2022, coinciding with post-COVID supply chain disruptions and the onset of the Russia–Ukraine war:

• Bosnia and Herzegovina (imports): Price abnormality of 5.2σ with a +22.6% price shift, affecting 11.2% of import value.
• India (imports): Price abnormality of 4.2σ with a +29.8% price shift, affecting 16.6% of import value.
• South Korea (exports): Price abnormality of 5.1σ with a +14.5% price shift, affecting 6.0% of export value.

These shocks, concentrated in a single year, highlight the sensitivity of bearing-parts trade to global disruptions. India and Bosnia and Herzegovina — two important supply sources — experienced the most pronounced import price anomalies.

3.3 Trade volatility is highest for smaller or geopolitically exposed partners

The coefficient of variation of trade flows reveals substantial volatility for certain partners. On the import side, Malaysia (CV 1.99), Hong Kong (1.07), and Ukraine (0.44) stand out as the most volatile sources. On the export side, Canada (0.77), Russia (0.70), and Ukraine (0.69) show the greatest instability. These high volatility scores likely reflect re-export flows (Hong Kong, Malaysia), geopolitical disruptions (Ukraine, Russia), or thin trading volumes (Canada).

The EU's trade intensity — the share of production that is traded internationally — rose from 54.2% to 83.8%, and export propensity increased from 40.1% to 65.6%. Both indicators point to a sector that is increasingly integrated into global value chains and therefore more exposed to external shocks.

Conclusion

Over the 2015–2025 period, the EU's bearing-parts trade has undergone a profound structural transformation. The bloc has shifted from near-autarky with a marginal trade surplus to a position of significant net import reliance (−300 €M deficit, 32% import reliance). This shift has been driven by the combination of declining export volumes (−50% in tonnes), surging imports from Asia (especially China, which nearly doubled its shipments), and a modest contraction in EU production.

The EU appears to be concentrating on higher-value-added bearing parts — export unit prices rose 62% — while ceding lower-end production to Asian competitors whose unit prices have actually declined. While this specialisation dynamic may reflect rational industrial choices, it carries strategic risks: import concentration (HHI) has risen to high levels, supply shocks were observed in 2022, and the sector's trade intensity now exceeds 83%, leaving it highly exposed to global disruptions.

Looking ahead, the key question is whether the EU can sustain its position in the high-value segment of this market while managing the growing import dependence that characterises the broader bearing-parts supply chain.
