Market evolution: Welding machine parts (CN 851590) — 2015–2025

Introduction

This report analyses the trade dynamics of EU trade in parts for soldering, welding, and hot-spraying machines (Customs code 851590) over the 2015–2025 period. The product category covers a broad range of spare and replacement parts used in industrial joining and surface-coating processes, excluding semiconductor wire bonders. Over the decade, the EU market for these parts underwent a profound structural transformation: export values rose while import values fell, unit prices diverged sharply, supply sources shifted dramatically, and the EU's net exporter position strengthened considerably. Three main dynamics emerge from the data, which this report explores in detail.

1. A price-driven export boom against a shrinking import base

Export values grew despite a collapse in traded volumes

Between 2015 and 2025, EU exports of CN 851590 increased in value from €601 million to €722 million (+20.1%), yet the physical volume exported fell from 12,247 tonnes to just 8,733 tonnes (−28.7%). The explanation lies in a surge in unit export prices, which climbed from €49,095 per tonne to €82,648 per tonne (+68.3%). In other words, the EU exported fewer parts but earned significantly more per unit shipped — a hallmark of a shift towards higher-value, more specialised components.

Import values contracted while prices held broadly steady

Over the same period, EU imports fell from €535 million to €359 million (−33.0%), with volumes declining from 13,985 tonnes to 9,870 tonnes (−29.4%). Unlike exports, however, import prices remained relatively flat, edging down from €38,278 to €36,335 per tonne (−5.1%). This divergence — rising export prices paired with stable import prices — widened the EU's average price premium from roughly €10,800/t to over €46,300/t, reflecting the EU's repositioning as a supplier of high-specification parts.

The trade balance shifted from modest surplus to strong net exporter status

The EU's trade balance in CN 851590 evolved as follows:

The balance dipped into deficit (−€109 million) around 2020, likely reflecting pandemic-era disruptions, before recovering sharply. Net import reliance moved from −24.7% in 2015 to −49.0% in 2025, confirming the EU's growing self-sufficiency in this product segment.

Domestic production expanded dramatically

Available PRODCOM data indicates that EU production value in CN 851590 surged from €330 million to €1.4 billion (+324.2%) over the period. This expansion underpins both the reduced import need and the capacity to export more in value terms, even as physical volumes declined.

2. A radical restructuring of import supply chains

Japan's near-total collapse as an import source

The most striking structural shift in EU imports by partner was the collapse of Japanese supply. Japanese imports peaked at €445 million before falling to just €15 million in 2025 — a 95% decline. Japan's coefficient of variation (0.84) confirms the extreme instability of this supply stream. This dramatic withdrawal likely reflects both the relocation of production capacity and intensified competition from other Asian suppliers.

China filled much of the void

China's share of EU imports more than doubled in value terms, rising from €51 million to €126 million (+145.3%). Notably, China's import price volatility (coefficient of variation of 0.21) was among the lowest of all major partners, suggesting relatively stable supply — though a significant price shock in 2022 (abnormality score of 56.4, with prices shifting by +46.7%) indicates some cost pressure from that source.

Import concentration fell sharply as supply diversified

The Herfindahl-Hirschman Index (HHI) for imports by value dropped from 3,491 to 1,970 (−43.6%), moving the EU import market from a moderately concentrated structure to a much more diversified one. This is a direct consequence of the de-concentration away from Japan and towards a wider set of suppliers including China, Türkiye, India, and Switzerland.

EU Member States' import patterns reflect shifting demand centres

Within the EU, import dynamics by Member State diverged significantly:

• Belgium saw imports collapse from €294 million to €3 million (−98.9%), suggesting the loss of a major re-distribution hub or the insourcing of a key end-user.
• Czechia (+449%) and Poland (+125%) experienced strong growth, consistent with the industrialisation of Central European manufacturing.
• Germany (+24.5%), the Netherlands (+8.7%), France (+13.7%), and Italy (+9.3%) showed moderate increases.

3. Geopolitical and sectoral shocks reshaped export destinations

The United States became the EU's dominant export market

EU exports by partner to the United States grew from €124 million to €179 million (+44.1%), making the US by far the largest single destination. However, this market was not without turbulence: a price shock in 2022 (abnormality of 7.2, price shift of −30.9%) affected nearly 29% of export value that year, coinciding with post-pandemic supply-chain rebalancing.

Russian exports were eliminated by sanctions

The most dramatic partner-level change was the complete collapse of exports to Russia, falling from €25 million in 2015 to virtually zero (€4,308) in 2025. This was a direct consequence of EU sanctions following the 2022 invasion of Ukraine. Russia's coefficient of variation for exports (0.60) captures the abruptness of this disruption.

Export diversification remained moderate

The HHI for exports by value edged up from 928 to 990 (+6.7%), indicating that exports remained broadly diversified but with a slightly growing concentration towards top destinations such as the US. The UK, a historically important market, saw exports decline by 25.2% — likely a consequence of post-Brexit trade frictions.

EU export leadership consolidated in Germany and Austria

Among EU exporting Member States, Germany remained dominant, growing from €288 million to €339 million (+17.9%). The most striking growth came from Austria (+230.0%, from €30 million to €99 million), Czechia (+90.3%), and Spain (+37.5%). France, by contrast, saw a decline of 30.7%, falling from €75 million to €52 million.

Specialisation data confirms Central and Northern European strengths

Revealed symmetric comparative advantage (RSCA) data for 2025 identifies Czechia (RSCA = 0.48), Romania (0.46), and Austria (0.45) as the EU Member States with the strongest specialisation in CN 851590 exports, while Bulgaria (−0.89), Ireland (−0.89), and Luxembourg (−0.87) are the least specialised. This pattern aligns with the broader Central European manufacturing cluster in industrial equipment components.

Conclusion

The EU market for welding and soldering machine parts (CN 851590) underwent a fundamental transformation between 2015 and 2025. The EU consolidated its position as a strong net exporter, with the trade balance quintupling from €66 million to €363 million. This was achieved not through volume growth — physical trade flows in both directions contracted — but through a decisive shift towards higher-value production. EU export unit prices rose by 68% while import prices barely moved, reflecting a move up the value chain.

On the import side, the most consequential change was the near-disappearance of Japan as a supplier, replaced in large part by China and a more diversified set of partners. On the export side, the elimination of Russian markets due to sanctions, the growing importance of the United States, and the rise of Austria and Czechia as export powerhouses reshaped the competitive landscape. Domestic EU production value more than quadrupled, supporting both reduced import dependence and expanded export capacity.

Looking ahead, key risks include continued exposure to Chinese supply concentration, dependence on the US as the largest single export market, and the potential for further geopolitical disruptions. The EU's strengthened net exporter position and improved import diversification, however, suggest a more resilient market structure than at the start of the period.
