Market evolution: Grinding and polishing machines (CN 846420) — 2015–2025

Introduction

This report analyses the evolution of EU trade in grinding and polishing machines for working stone, ceramics, concrete, and similar mineral materials (excluding hand-held machines), classified under Combined Nomenclature code 846420. The period under review spans from 2015 to 2025. Over this decade, the EU's trade dynamics for this specialized industrial equipment have undergone a significant transformation. The analysis reveals a narrative of a declining European trade surplus, driven by diverging trends in export volumes and import values. Key findings include a structural shift in the EU's competitive position, a reconfiguration of its major trade partners, and notable volatility in certain product segments. The following sections dissect these main trends to provide a comprehensive market overview.

1. A Structural Shift from Net Exporter to Net Importer

The most profound change over the period is the erosion of the EU's traditional trade surplus. While the EU remains a major exporter, the growth of imports has outpaced that of exports, fundamentally altering the trade balance. This shift is evident across multiple indicators.

1.1 The Erosion of the EU Trade Surplus

The EU started the period with a solid trade surplus of €219.3 million in 2015. By 2025, this surplus had decreased to €173.5 million, a decline of -20.9%. This narrowing is not due to a collapse of exports but rather to a dramatic surge in import values. The General Overview shows that while export value only fell by -4.8%, import value increased by 100.2%, effectively doubling from €33.6 million to €67.3 million.

1.2 Divergent Trends in Volume and Price

The underlying drivers of this shift become clear when examining volume and price separately. EU export performance suffered a significant volume contraction of -30.1% in tonnes, from 14,199t to 9,925t. To counterbalance falling volumes, exporters shifted towards higher-value products, pushing the average export price up by 36.2% to €24,260 per tonne. In contrast, import volumes grew by 63.0%, and their average price also increased, albeit at a slower rate of 22.8%. This indicates that while the EU is buying more equipment from abroad, it is specializing in exporting more expensive machinery.

2. Weakening Specialization and Domestic Production

The trade balance shift is mirrored by indicators of the EU's internal productive capacity and competitive edge. Data on specialisation and production volumes suggests a contraction in the EU's home-based manufacturing activity for these machines.

2.1 Erosion of Comparative Advantage

The EU's net import reliance, while remaining negative (indicating a surplus), moved from -76.0% in 2015 to a more extreme -701.3% in 2025. This extreme negative value is an artifact of the formula and underscores that the EU's exports vastly exceed its imports on a per-unit-of-production basis, but the trend shows a movement towards greater self-sufficiency or reduced export dominance. More tellingly, the Market Structure data shows that while Italy maintains a strong revealed symmetric comparative advantage (RSCA of 0.67), Germany's advantage is minimal (RSCA of 0.03), and many EU members are net importers of this technology.

2.2 A Decline in EU Production

The decline is not just a trade phenomenon. Reported EU production of these machines fell sharply. Production quantity in items plummeted by -56.7%, from 9,708 units in 2015 to 4,200 units in 2025. Production value also decreased by -13.7% over the same period, from €280.8 million to €242.4 million (Production Volumes). This drop in output volume, even as unit values (price) may have risen, points to a potential hollowing out of domestic manufacturing capacity.

3. Geographic Reconfiguration and Segment Volatility

The transformation in trade flows has not been uniform across partners or product sub-categories. Certain regions and product segments have emerged as critical drivers of the observed trends, often with high volatility.

3.1 The Rising Role of Asian and US Suppliers into the EU

The composition of EU imports has evolved significantly. China has solidified its position as the top import source, increasing its share by 79.2% to €19.9 million by 2025. The most dramatic increase, however, comes from Switzerland, where imports surged by 579.3%, jumping from €2.5 million to €17.0 million, potentially reflecting high-precision or specialized machinery flows. Imports from the United States also grew substantially (+174.9%). This growth from multiple partners, especially Switzerland and the US, alongside China, has diversified but also increased the overall import bill (Top Partners by Value).

3.2 Export Market Dynamics: Resilience and Loss

On the export side, the United States remains the top destination, though its value decreased by -14.0%. A major success story is Türkiye, where EU exports more than doubled (+168.6%). Conversely, exports to the United Kingdom declined by -38.0%, and exports to Algeria collapsed by -86.9%. The EU's export market concentration, measured by the Herfindahl-Hirschman Index (HHI), increased by 23.9%, indicating a modest reduction in export destination diversity (Concentration).

3.3 Product Sub-Segments: Differentiated Paths

The trade is not monolithic across the sub-products of CN 846420. For exports, the segment for grinding machines for cold-working optical glass (84642011) saw a 53.0% increase in value to €80.5 million in 2025, driven by high unit values (over €89,000 per tonne). In contrast, exports of machines for stones, concrete, etc. (84642080) and non-optical glass (84642019) declined in value and volume. For imports, all sub-segments grew, but the growth in value for optical glass (84642011) machines was more moderate (+54.8%) compared to the explosive growth in imports for stones, concrete, etc. (84642080) (+156.1%). This highlights how market dynamics differ sharply by end-use application (Product Segment Breakdown).

Conclusion

The EU market for grinding and polishing machines (CN 846420) between 2015 and 2025 has transitioned from a position of stable dominance to one facing significant competitive pressures. The core narrative is the rapid growth of imports—especially from China, Switzerland, and the US—which has eroded the EU's trade surplus. This has occurred alongside a worrying decline in both production volumes and unit production, suggesting a potential restructuring of the European supply chain. While the EU retains leadership in high-value, specialized segments like optical glass grinding machinery, its overall competitive edge, as measured by specialisation indices, has weakened for many member states. The market is also becoming more geographically concentrated on the export side. These trends point towards a sector undergoing global rebalancing, where the EU's future strength may lie more in high-tech, niche applications than in broad-based production volumes. The stability of this new equilibrium, particularly given the volatility observed in specific trade flows (as seen in the Volatility & Shocks data), remains a key area to monitor.
