Market evolution: Resistance welding machines (CN 851521) — 2015–2025
Introduction
This report examines the trade dynamics of fully or partly automatic machines for resistance welding of metals (Combined Nomenclature code 851521) by the European Union with non-EU countries over the period 2015–2025. Resistance welding equipment is a critical industrial input for automotive, aerospace, and metal fabrication sectors. The period under review covers several structurally significant events — including Brexit (2020–2021), the COVID-19 pandemic, and the Russia–Ukraine conflict — that have reshaped supply chains and trade patterns. Drawing on Eurostat trade data, this analysis reveals a market characterised by a strengthening EU trade surplus, a dramatic contraction in import volumes, a geographic reorientation of export flows toward the Americas, and a shift toward higher-value-added shipments.
For the full data overview, see the General Overview.
1. The EU's decisive shift from balanced trade to net exporter
The most striking feature of the 2015–2025 period is the EU's transformation from a relatively balanced trader of resistance welding machines into a dominant net exporter. Several indicators converge to illustrate this structural shift.
1.1 Trade surplus more than doubled over the decade
The EU's trade balance in resistance welding machines widened from €147.3 million in 2015 to €240.8 million in 2025, an increase of 63.5%. The surplus reached its peak at approximately €378.7 million during the period, reflecting the combined effect of growing export values and collapsing import volumes. The trade balance trajectory shows a clear structural improvement that extends beyond cyclical fluctuations.
1.2 Export values held firm while import values nearly halved
EU exports of resistance welding machines grew modestly in value terms, from €296.3 million in 2015 to €318.6 million in 2025 (+7.5%), while export volumes actually declined by 16.9% (from 10,833 tonnes to 8,997 tonnes). This divergence is explained by a 29.5% increase in average unit export prices (from approximately €27,352/t to €35,408/t), indicating that EU manufacturers increasingly specialised in higher-specification equipment.
Conversely, imports underwent a far more dramatic contraction. Import values fell 47.8% (from €149.0 million to €77.8 million), while import volumes collapsed by 67.8% (from 8,035 tonnes to 2,589 tonnes). The gap between the value and volume decline is explained by a 62.1% surge in import prices (from approximately €18,539/t to €30,053/t), suggesting that the EU's residual imports concentrated on higher-end, more specialised machines.
1.3 Net import reliance turned decisively negative
The net import reliance ratio — which measures the balance between imports and domestic production — swung from –27.9% in 2015 to –100.1% in 2025. A negative value indicates net exporting status; the deepening negativity means the EU not only satisfied its domestic demand from local production but exported an amount roughly equal to its entire production output. This transformation, shown on the net import reliance dashboard, underscores the EU's strengthened competitive position in this product segment.
| Indicator | 2015 | 2025 | Change |
|---|---|---|---|
| Export value (€M) | 296.3 | 318.6 | +7.5% |
| Export volume (t) | 10,833 | 8,997 | –16.9% |
| Export price (€/t) | 27,352 | 35,408 | +29.5% |
| Import value (€M) | 149.0 | 77.8 | –47.8% |
| Import volume (t) | 8,035 | 2,589 | –67.8% |
| Import price (€/t) | 18,539 | 30,053 | +62.1% |
| Trade balance (€M) | 147.3 | 240.8 | +63.5% |
| Net import reliance (%) | –27.9 | –100.1 | –259.3% |
2. Geographic reorientation: the Americas replace traditional European partners
The data reveals a profound geographic reorientation in both import sourcing and export destinations, with the Americas gaining prominence and several traditional European partners declining sharply.
2.1 Import sourcing shifted away from the UK and South Korea toward Switzerland
The most dramatic import-side changes concern the United Kingdom and South Korea. UK-sourced imports plummeted by 92.0%, from €30.5 million in 2015 to just €2.4 million in 2025 — a decline almost certainly linked to Brexit and the reclassification of UK–EU trade flows. South Korean imports fell 73.2% (from €74.5 million to €20.0 million), suggesting either a loss of competitiveness or a redirection of Korean manufacturers' export strategies.
By contrast, Switzerland emerged as the EU's largest single import source in 2025 with €30.2 million (+105.2% over the period), reflecting the importance of Swiss precision engineering firms in this segment. China's share remained relatively stable (€8.7 million to €9.9 million, +13.5%), while Türkiye more than quintupled its shipments (€0.3 million to €1.7 million, +451.6%).
| Import partner | 2015 (€M) | 2025 (€M) | Change |
|---|---|---|---|
| United Kingdom | 30.5 | 2.4 | –92.0% |
| Korea, Republic of | 74.5 | 20.0 | –73.2% |
| Switzerland | 14.7 | 30.2 | +105.2% |
| China | 8.7 | 9.9 | +13.5% |
| Japan | 4.4 | 2.1 | –52.3% |
| United States | 3.5 | 3.9 | +12.4% |
| Türkiye | 0.3 | 1.7 | +451.6% |
2.2 Export destinations shifted strongly toward Mexico and Brazil
On the export side, the most remarkable growth was in shipments to Latin America. Exports to Mexico surged by 258.4% (from €12.2 million to €43.7 million), making it one of the EU's top three export markets by 2025. Brazil grew by 164.3% (from €10.0 million to €26.3 million). This export partner dynamic likely reflects the expansion of automotive manufacturing capacity in Mexico (integrated into North American supply chains) and industrialisation efforts in Brazil.
The United States remained the EU's single largest export destination, growing by 33.2% (from €73.1 million to €97.4 million) and accounting for nearly a third of total EU exports. Meanwhile, exports to the Russian Federation fell by 50.5% (from €28.6 million to €14.2 million), with the decline accelerating after 2022 due to EU sanctions following the invasion of Ukraine.
| Export partner | 2015 (€M) | 2025 (€M) | Change |
|---|---|---|---|
| United States | 73.1 | 97.4 | +33.2% |
| United Kingdom | 32.9 | 28.2 | –14.2% |
| Russian Federation | 28.6 | 14.2 | –50.5% |
| China | 38.0 | 34.2 | –10.1% |
| Türkiye | 14.0 | 17.0 | +21.9% |
| Mexico | 12.2 | 43.7 | +258.4% |
| Brazil | 10.0 | 26.3 | +164.3% |
2.3 Import concentration declined while export concentration increased
The Herfindahl-Hirschman Index (HHI) for imports fell from 3,114 to 2,408 (–22.7%), indicating that the EU diversified its import sources away from heavy reliance on a small number of suppliers (notably South Korea and the UK). For exports, the HHI rose from 1,097 to 1,439 (+31.3%), suggesting a moderate concentration of export flows toward a handful of large markets — principally the United States. The full concentration analysis provides further detail.
3. Domestic production contracted but EU manufacturers maintained competitive edge
Behind the trade figures lies a story of domestic industrial restructuring: EU production volumes and values declined, yet the bloc's exporters maintained their technological edge and even improved their price positioning.
3.1 EU production output fell significantly
EU production of resistance welding machines (as measured by PRODCOM data) declined from approximately 115,165 units (valued at €1.16 billion) in 2015 to an estimated 80,000 units (valued at €600 million) in 2025 — a 30.5% drop in volume and a 48.1% drop in value. Production peaked at roughly 289,912 units and €1.54 billion during the period. This contraction likely reflects consolidation among EU manufacturers, offshoring of lower-end production, and cyclical weakness in key customer sectors (particularly European automotive).
Yet the decline in production did not translate into a weaker trade position, because exports held firm in value while imports collapsed even faster.
3.2 Germany and Italy anchor EU export specialisation
Specialisation data for 2025 confirms that Germany and Italy are the EU's dominant producers and exporters of resistance welding machines. Both countries exhibit revealed symmetric comparative advantage (RSCA) values of approximately 0.36 and RCA indices above 2.1, indicating strong competitive positioning in global markets. Germany accounts for roughly 44.9% of EU production and 21.2% of total EU exports in this product, while Italy contributes 17.0% of production and 8.0% of exports.
The specialisation analysis also reveals that Austria, the Netherlands, and Greece maintain positive comparative advantages, while most other EU member states are net importers or have negligible production.
| Member State | RSCA (2025) | RCA (2025) | Production share | Export share |
|---|---|---|---|---|
| Germany | 0.359 | 2.119 | 44.9% | 21.2% |
| Italy | 0.358 | 2.115 | 17.0% | 8.0% |
| Greece | 0.157 | 1.372 | 0.9% | 0.7% |
| Netherlands | 0.109 | 1.244 | 18.1% | 14.5% |
| Austria | 0.015 | 1.031 | 3.4% | 3.3% |
3.3 Trade intensity and export propensity surged
Two autonomy indicators confirm the EU's deepening orientation toward international markets. Trade intensity — the share of production traded internationally — rose from 32.9% in 2015 to 65.0% in 2025 (+97.8%). Export propensity — the share of production that is exported — climbed from 28.4% to 61.1% (+115.1%). These figures indicate that while absolute production volumes fell, EU manufacturers became far more export-oriented, selling a growing share of a smaller output to international customers.
3.4 Price shocks signal supply chain turbulence
The volatility analysis detected several notable price shocks during the period. The most extreme was a 365.6% price spike in imports from the United Kingdom centred on 2021, coinciding with Brexit-related customs disruptions. A 264.7% price shock in exports to South Africa in 2022 and a 189.3% shock in exports to Mexico in 2020 also stand out. These events, while isolated, highlight the sensitivity of specialised industrial equipment trade to regulatory and macroeconomic disruptions.
Conclusion
Over the 2015–2025 period, the EU resistance welding machine market (CN 851521) underwent a fundamental transformation. The bloc evolved from a moderately self-sufficient producer into a dominant net exporter, with a trade surplus that expanded by over 60% despite a significant contraction in domestic production. This apparent paradox is resolved by the simultaneous collapse of import volumes (–67.8%) and the shift toward higher-value-added exports, whose average unit prices rose nearly 30%.
Geographically, the trade map was redrawn: Brexit decimated UK–EU flows in this product, South Korean imports retreated sharply, and Latin American markets — especially Mexico and Brazil — emerged as critical growth destinations for EU exporters. Germany and Italy remained the industrial backbone of European production, with strong comparative advantages that show no signs of erosion.
Looking ahead, the EU's deep export orientation (with over 60% of production destined for international markets) exposes the sector to demand-side risks in key partner economies, particularly the United States. However, the demonstrated ability of EU manufacturers to maintain price premiums and the diversification of export flows toward emerging markets suggest a structurally resilient competitive position. The main vulnerability lies not in import dependency — which has effectively been eliminated — but in potential disruptions to outbound supply chains and in the continued erosion of domestic production capacity.
