Market evolution: Centrifuge parts (CN 842191) — 2015–2025

Introduction

This report analyses the evolution of European Union trade in parts for centrifuges and centrifugal dryers (customs code 842191) over the period 2015–2025. The product category, classified under PRODCOM code 28.29.82.20 ("Parts for centrifuges and centrifugal dryers"), covers replacement and auxiliary components for industrial separation equipment used across pharmaceuticals, chemicals, food processing, and wastewater treatment.

Over the eleven-year window, the EU consolidated its position as a major net exporter of centrifuge parts. The trade surplus grew from €227 million to €364 million (+61%), while EU production value nearly tripled, rising from €142 million to €420 million. The most striking feature of the period is a pronounced divergence between export and import unit values: export prices surged by 47% while import prices remained essentially flat, pointing to the EU's growing specialisation in high-value-added segments of the centrifuge parts market.

The following sections examine this trajectory in detail, focusing on trade balance dynamics, the internal European production landscape, and the evolving geography of external partnerships.

A Robust Trade Surplus Strengthened by Divergent Price Trends

The EU's trade surplus widened by 61% despite faster growth in import volumes

The EU's trade balance for centrifuge parts expanded from €226.8 million in 2015 to €364.1 million in 2025. This growth was sustained despite the fact that import volumes grew nearly seven times faster than export volumes over the same period:

The surplus's resilience rests entirely on the price premium that EU exporters command: while volumes grew modestly, the 47% increase in export unit prices more than compensated for the near-doubling of import quantities.

Export unit values rose 47% while import prices remained flat

The most significant dynamic of the period is the widening gap between export and import unit prices. In 2015, EU exports were priced at €85,553 per tonne — roughly three times the import unit value of €28,993 per tonne. By 2025, this ratio had widened to approximately 4.5:1, with exports at €125,725 per tonne and imports at €28,075 per tonne.

This divergence reflects a classic pattern of industrial specialisation: the EU increasingly focuses on high-precision, proprietary, or custom-engineered centrifuge components (such as rotors, bearings, or control systems), while importing more commoditised or standardised parts — often from lower-cost manufacturing bases. The flat import unit price despite a near-doubling of volumes suggests that import sourcing has shifted towards more cost-effective suppliers, likely in Asia and Türkiye.

Net import reliance deepened as the EU strengthened its exporter role

The net import reliance indicator, which measures the ratio of net trade to production, moved from −55% in 2015 to −734% in 2025. These deeply negative values confirm that the EU is a substantial net exporter of centrifuge parts. Concurrently, the export propensity — the ratio of exports to domestic production — rose from 68% to 120%, meaning that EU exports now exceed reported domestic production. This is consistent with the EU serving as a hub for centrifuge part manufacturing, with significant re-export or intra-firm trade activity.

A European Production Base Built on German and Nordic Strength

EU production value nearly tripled between 2015 and 2025

According to PRODCOM data, the EU's domestic production of centrifuge parts rose from €142 million to €420 million over the period — a gain of 196%. This growth trajectory significantly outpaced the 66% increase in export value, suggesting that a growing share of output is being absorbed within the EU's internal market, possibly by centrifuge manufacturers assembling final products for export under other tariff codes.

Germany and Sweden together account for over 70% of extra-EU exports

The concentration of export capacity within the EU is striking. Germany and Sweden dominate, while several smaller member states recorded exceptional growth rates:

Germany alone accounted for approximately €191 million in exports in 2025 (38% of the EU total), reflecting its position as home to major centrifuge manufacturers. Sweden's near-doubling of exports to €165 million is consistent with the global expansion of Swedish separation technology companies. Poland's remarkable +418% growth signals its integration into European centrifuge supply chains, likely as a manufacturing platform serving both EU and global markets.

France is a notable exception, with exports declining by 27% — a contraction that may reflect shifting production footprints or competitive pressures.

Specialisation data confirms a northern European industrial core

The Revealed Symmetric Comparative Advantage (RSCA) analysis for 2025 identifies a clear hierarchy of specialisation within the EU:

Sweden and Slovakia exhibit the highest specialisation intensity, with RCA values of 6.9 and 4.8 respectively, indicating that centrifuge parts represent a far more prominent export category for these countries than for the EU average. Germany, while showing moderate specialisation (RCA 1.54), dominates in absolute terms, producing one-third of EU output. The least specialised member states — Portugal, Luxembourg, Romania, Cyprus, and Croatia — have negligible presence in this sector.

Diversifying Trade Partners with Isolated but Notable Price Shocks

China, India, and Türkiye drove the fastest import growth

The geography of EU imports shifted meaningfully over the period, with emerging-economy suppliers gaining ground against traditional partners:

Switzerland remains the largest single source of imports at €35 million, reflecting its role as a precision engineering hub. However, the fastest growth came from Türkiye (+181%), India (+144%), and China (+115%), all of which roughly doubled or more than doubled their sales to the EU. These three countries likely supply standardised or lower-cost components, consistent with the flat import unit price trend noted above. Meanwhile, imports from the United Kingdom declined by 11% and those from Japan by 29%, suggesting a gradual reorientation of sourcing patterns.

The United States and Singapore are the EU's largest export markets

On the export side, the United States remained the primary destination throughout the period:

The United States absorbed €132 million in EU centrifuge parts in 2025 — over one-quarter of all extra-EU exports — reflecting deep integration between transatlantic pharmaceutical and industrial supply chains. Singapore's position as the second-largest market (€66 million) likely reflects its role as a regional distribution hub for Southeast Asian manufacturing. Türkiye recorded the fastest export growth at +157%, consistent with its industrialisation and growing demand for separation technology.

Import concentration declined while export concentration increased slightly

The Herfindahl-Hirschman Index (HHI) reveals divergent concentration trends:

Import concentration fell from 1,700 to 1,554, crossing below the 1,500 threshold typically associated with moderate concentration. This indicates that the EU diversified its import base, reducing reliance on any single supplier. Export concentration, while remaining in the low-concentration zone, rose modestly from 977 to 1,110, reflecting the growing weight of the United States and Singapore as destinations.

Isolated price shocks affected specific bilateral trade flows

The volatility analysis reveals that most trade flows were relatively stable, but three notable price shocks were detected:

Source: EU supply shocks data

The most significant shock was a 57% price spike in EU imports from the United Kingdom in 2022, affecting flows representing 13.7% of total import value. This timing coincides with the full implementation of post-Brexit customs arrangements and broader global supply chain disruptions. The shock was not sustained in subsequent years. The Türkiye export price shock in 2017 and the Norway export price shock in 2018 were smaller in scale and appear to be idiosyncratic.

The volatility coefficients further confirm that bilateral trade with Malaysia (CV 1.54) and Serbia (CV 1.03) was highly volatile on the import side, while Saudi Arabia (CV 0.59) and Türkiye (CV 0.55) showed elevated volatility on the export side. By contrast, imports from Switzerland (CV 0.22) and Canada (CV 0.23), and exports to Norway (CV 0.12) and the United States (CV 0.12), showed remarkably low volatility — consistent with long-established, stable trade relationships.

Conclusion

The EU's centrifuge parts sector (CN 842191) demonstrated strong performance between 2015 and 2025, characterised by a deepening trade surplus, rising production, and increasing specialisation in high-value segments. The trade surplus grew by 61% to €364 million, driven almost entirely by a 47% increase in export unit prices rather than by volume expansion. Meanwhile, import volumes nearly doubled at stable prices, suggesting growing sourcing of commoditised components from emerging-economy suppliers.

Within the EU, Germany and Sweden dominate both production and exports, together accounting for over 70% of extra-EU export value. Poland emerged as a fast-growing player, with exports increasing over fourfold, signalling its integration into European centrifuge supply chains. Specialisation is heavily concentrated in northern and central Europe, while southern and peripheral member states have minimal presence in this sector.

On the external front, the EU diversified its import base, reducing concentration risks, while export markets remained anchored by the United States and Singapore. Isolated price shocks — most notably a 57% import price spike from the United Kingdom in 2022 — did not disrupt the overall trajectory. The combination of growing production capacity, rising export propensity (now exceeding 100% of domestic output), and strengthening specialisation suggests the EU is well-positioned to maintain its competitive edge in this niche of capital goods manufacturing.
