Market evolution: Stainless steel welded tubes (CN 730640) — 2015–2025
Introduction
This report examines the evolution of EU external trade in stainless steel welded tubes of circular cross-section (Combined Nomenclature code 730640) over the period 2015–2025. The product covers welded tubes, pipes and hollow profiles of stainless steel with a diameter ≤ 406.4 mm, excluding oil and gas pipeline products. It is a significant industrial intermediate good used across chemical processing, food and beverage, pharmaceutical, and construction sectors.
Over the decade, the EU has maintained a structural trade surplus in this product. However, the data reveals a pronounced erosion of that surplus — not because exports collapsed in value terms, but because import volumes surged while export volumes contracted sharply. Simultaneously, unit values on the export side roughly doubled, indicating a fundamental shift toward higher-value, lower-volume trade flows. These dynamics reflect a combination of rising Asian competition, geopolitical disruptions (Brexit, Russia sanctions), and cost-driven repricing of stainless steel products.
The analysis is structured around three main themes: the erosion of the EU's trade surplus, the geographic reorientation of trade partners, and the role of price inflation and production shifts in reshaping market structure.
A Shrinking Surplus: Diverging Trajectories of EU Exports and Imports
Export value held up despite a dramatic volume decline
The headline figures conceal a striking divergence between value and volume on the export side. Between 2015 and 2025, EU exports of CN 730640 fell from 130,318 tonnes to 82,720 tonnes — a contraction of 36.5%. Yet export value remained relatively stable, moving from €544.1 million to €574.8 million (+5.6%). The explanation lies entirely in unit prices: the average export price rose from €4,175/t to €6,947/t, an increase of 66.4%.
| Indicator | 2015 | 2025 | Change |
|---|---|---|---|
| Export value (€M) | 544.1 | 574.8 | +5.6% |
| Export quantity (t) | 130,318 | 82,720 | −36.5% |
| Export price (€/t) | 4,175 | 6,947 | +66.4% |
| Import value (€M) | 183.4 | 303.5 | +65.5% |
| Import quantity (t) | 47,242 | 74,790 | +58.3% |
| Import price (€/t) | 3,881 | 4,058 | +4.6% |
| Trade balance (€M) | 360.7 | 271.3 | −24.8% |
Overview of EU trade in CN 730640
Import growth was both volume-driven and structurally significant
On the import side, the story is nearly the inverse: volumes grew by 58.3% (from 47,242 t to 74,790 t), and values rose by 65.5% (from €183.4 million to €303.5 million). Unlike exports, import prices rose only modestly (+4.6% over the decade), indicating that the EU's import growth was driven primarily by expanding quantities of competitively priced product rather than by cost inflation.
The combined effect is a trade balance that narrowed from €360.7 million in 2015 to €271.3 million in 2025, a decline of 24.8%. The net import reliance metric remained negative throughout (confirming the EU's net-exporter status), but moved from −16.4% to −9.1%, indicating a progressive erosion of the EU's competitive position in global markets.
The two sub-segments tell different stories
CN 730640 is bundled from two sub-codes: 73064080 (standard welded stainless tubes) and 73064020 (cold-drawn or cold-rolled welded stainless tubes). Their trajectories diverge considerably.
| Sub-segment | Flow | 2015 Qty (t) | 2025 Qty (t) | 2015 Price (€/t) | 2025 Price (€/t) |
|---|---|---|---|---|---|
| 73064080 (standard) | Imports | 32,232 | 53,652 | 3,503 | 3,824 |
| 73064080 (standard) | Exports | 71,689 | 58,781 | 4,592 | 6,070 |
| 73064020 (cold-worked) | Imports | 15,011 | 21,138 | 4,692 | 4,653 |
| 73064020 (cold-worked) | Exports | 58,629 | 23,940 | 3,665 | 9,100 |
The cold-worked segment (73064020) experienced a collapse in export volumes — from 58,629 t to 23,940 t, a drop of nearly 59% — while its export unit value soared from €3,665/t to €9,100/t. This suggests that EU producers progressively exited the lower end of the cold-worked segment, retaining only premium-value niches. By contrast, import volumes in 73064020 grew only modestly (from 15,011 t to 21,138 t) and import prices were essentially flat, indicating that third-country suppliers are competing primarily on standard-grade products.
Geographic Reorientation: New Suppliers Enter as Old Partners Fade
Asia-Pacific has become the dominant source of EU imports
The most striking geographic shift in imports is the rapid rise of Asian suppliers. China's exports to the EU more than doubled in value, rising from €37.3 million in 2015 to €82.6 million in 2025 (+121.4%), making it the largest single source of imports by value. Taiwan, already the leading supplier at the start of the period, grew from €55.3 million to €69.7 million (+26.0%). But the most dramatic growth came from Viet Nam, which went from virtually nothing (€77,546) to €28.4 million — an increase of over 36,000% — reflecting the rapid development of Vietnamese stainless steel pipe manufacturing for export.
| Import partner | 2015 (€M) | 2025 (€M) | Change |
|---|---|---|---|
| Taiwan | 55.3 | 69.7 | +26.0% |
| China | 37.3 | 82.6 | +121.4% |
| United Kingdom | 18.9 | 7.2 | −62.2% |
| Viet Nam | 0.08 | 28.4 | +36,463% |
| Switzerland | 25.4 | 38.9 | +53.0% |
| Türkiye | 4.7 | 20.1 | +327.7% |
| Korea, Republic of | 13.1 | 17.1 | +30.3% |
The United Kingdom's role diminished sharply post-Brexit
The UK is the only major import partner that saw a significant decline, falling from €18.9 million to €7.2 million (−62.2%). This is consistent with the UK's departure from the EU single market and customs union at the end of the transition period (January 2021), which introduced new customs procedures and regulatory divergence. The volatility data confirms this instability: the UK import coefficient of variation stands at 0.84, the third highest among import partners after Malaysia and Viet Nam, indicating highly erratic trade flows.
EU export destinations were reshaped by geopolitics
On the export side, Russia's collapse is the most dramatic story. EU exports to the Russian Federation fell from €24.4 million to €1.7 million (−93.2%), almost entirely due to EU sanctions imposed following the invasion of Ukraine. The coefficient of variation for Russia-bound exports is 0.59, reflecting the sharp discontinuity. India also declined significantly, from €27.1 million to €10.4 million (−61.6%), likely reflecting India's own capacity build-up and import substitution policies.
| Export partner | 2015 (€M) | 2025 (€M) | Change |
|---|---|---|---|
| United Kingdom | 99.6 | 119.9 | +20.3% |
| Switzerland | 56.2 | 68.1 | +21.0% |
| Türkiye | 55.1 | 53.0 | −3.9% |
| Norway | 29.8 | 68.2 | +129.1% |
| India | 27.1 | 10.4 | −61.6% |
| United States | 41.2 | 75.8 | +83.7% |
| Russian Federation | 24.4 | 1.7 | −93.2% |
The United States emerged as a major growth market, with EU exports rising from €41.2 million to €75.8 million (+83.7%). Norway also nearly doubled its intake, reaching €68.2 million. These two markets partially compensated for the loss of Russia and India, though the overall export volume decline shows the compensation was incomplete.
EU member states saw a reshuffling of roles
Within the EU, Italy remained the dominant exporter, accounting for €189.7 million in 2025 (down slightly from €206.0 million). Germany was the second-largest exporter at €136.7 million (down from €154.3 million). However, Austria's exports surged from €16.7 million to €80.6 million (+384.2%), suggesting a major capacity expansion or reallocation of production. Finland also grew meaningfully, from €26.5 million to €36.9 million.
On the import side, Germany was the largest importing member state (€57.6 million), followed by the Netherlands (€37.1 million), Poland (€36.8 million), and Italy (€24.1 million). Notably, Poland and Italy showed the fastest import growth (+113.7% and +135.0% respectively), suggesting growing demand and possibly increasing use of imported stainless tubes in domestic manufacturing.
Price Inflation, Production Shifts, and Supply Concentration
EU production value surged while volumes grew only modestly
According to PRODCOM production data, EU production of CN 730640 in volume terms rose only 6.0%, from 1,170,759 kg (1,171 tonnes) to 1,240,487 kg (1,240 tonnes). However, production value in euros increased by 179.6%, from €1.34 billion to €3.75 billion. This enormous gap between volume and value growth is consistent with the broader stainless steel market dynamic of the period: the cost of nickel, chromium, and energy inputs surged after 2020, driving up the price of both raw materials and finished stainless products. The EU production data likely captures a real repricing of output rather than a quality shift alone.
Italy and Finland are the EU's most specialised producers
The specialisation analysis for 2025 reveals that Italy has by far the highest revealed comparative advantage (RCA of 6.69, RSCA of 0.74), accounting for 53.6% of all EU exports in this product. Finland follows with an RCA of 3.99. Denmark, Austria, and Estonia also show positive RSCA values. At the other end of the spectrum, Ireland, Bulgaria, Hungary, Luxembourg, and Croatia have no meaningful specialisation in this product, with RSCA values below −0.80. This concentration pattern underscores the importance of Italy's industrial district model (particularly in the Brescia region) for European stainless tube production.
Import concentration remained moderate; export concentration increased
The Herfindahl-Hirschman Index (HHI) for import sources declined slightly from 1,752 to 1,637 (by value), indicating a moderate level of supplier concentration that is gradually easing as more countries — particularly Viet Nam and Türkiye — enter the market. Export concentration, however, increased from 757 to 1,043, suggesting that EU exports became more geographically concentrated over the period, likely driven by the loss of smaller or more volatile markets (Russia, India) and the growing weight of a few large stable partners (UK, US, Norway).
Supply shocks were limited but geographically specific
The volatility and shock analysis identified three notable price shocks, all on the export side. The most extreme was a price spike in exports to Oman in 2021, with an abnormality score of 82.0 and a 346.4% shift, though Oman represented only 3.5% of export value — suggesting a possible one-off transaction or small-volume distortion. A similar but smaller shock affected Morocco in the same year. In 2022, Serbia experienced a price shock of 28.8%. None of these shocks appear to reflect systemic supply disruptions; rather, they are consistent with the idiosyncratic volatility of small-volume trade relationships. Among import partners, Malaysia (CV of 1.54) and Viet Nam (CV of 0.88) showed the highest overall volatility, consistent with their emerging and still-irregular trade patterns with the EU.
Conclusion
The EU market for stainless steel welded tubes (CN 730640) underwent a fundamental transformation between 2015 and 2025. While the EU remained a net exporter throughout the period, its trade surplus eroded by nearly a quarter in value terms, driven by a combination of rising import volumes (especially from China, Taiwan, Viet Nam, and Türkiye) and declining export volumes.
The most important structural change was the price-volume divergence on the export side: EU producers shipped significantly fewer tonnes but at substantially higher unit values, suggesting a shift toward higher-grade or more specialised products and away from commodity-grade competition. This is consistent with EU producers facing cost pressures from energy and raw materials that priced them out of standard segments, where Asian suppliers increasingly dominate on price.
Geopolitical events — Brexit, Russia sanctions, and the broader US-China trade tensions — visibly reshaped trade flows, redirecting EU exports toward the United States and Norway while eliminating Russia as a market. The rapid emergence of Viet Nam as a supplier (from near-zero to €28.4 million in a decade) points to a broader trend of supply-chain diversification in Asia.
Looking forward, the continued growth of import volumes (up 58.3% over the decade) combined with declining export propensity (from 20.8% to 16.0%) suggests that the EU's self-sufficiency in this product is gradually weakening. EU producers — concentrated heavily in Italy, Germany, Austria, and Finland — will likely need to continue moving up the value chain to maintain competitiveness against an increasingly diversified and price-competitive import base.
