Market evolution: Steel fasteners (CN 7318) — 2015–2025
Introduction
This report examines the evolution of EU trade in steel fasteners (customs code 7318) over the period 2015–2025. The product heading covers a broad family of iron and steel articles — screws, bolts, nuts, rivets, washers, cotters and related items — that are fundamental inputs to construction, automotive, machinery, and infrastructure sectors. The scope and definitions confirm that CN 7318 is a bundling heading encompassing twelve six-digit sub-headings, from coach screws (731811) to non-threaded articles n.e.s. (731829).
Over the eleven years under review, the EU's external trade in steel fasteners underwent three major transformations: a strong price-driven expansion that significantly narrowed the trade deficit; a pronounced geographic reorientation of both imports and exports; and a structural shift in production and market concentration that has reshaped the EU's competitive position. The following sections examine each of these dynamics in turn.
1. Price-Driven Growth and the Narrowing Trade Deficit
1.1 Export values rose sharply while volumes stagnated
Between 2015 and 2025, EU exports of steel fasteners grew from €3.86 billion to €5.80 billion — an increase of 50.1% (General Overview – trade). Yet export quantities barely changed, declining slightly from 553,024 tonnes to 547,552 tonnes (−1.0%). The entire increase in export value was therefore driven by unit prices, which rose from €6,985/t to €10,586/t — a gain of 51.5%.
This pattern suggests that EU exporters increasingly competed on quality, specialisation, and value-added rather than on volume. The product segment breakdown illustrates this clearly at the sub-heading level. For example:
| Sub-heading | Export price 2015 (€/t) | Export price 2025 (€/t) | Change |
|---|---|---|---|
| 731815 – Threaded screws & bolts | 5,842 | 8,146 | +39.4% |
| 731816 – Nuts | 8,759 | 15,957 | +82.2% |
| 731814 – Self-tapping screws | 5,982 | 8,440 | +41.1% |
| 731822 – Washers | 10,223 | 20,507 | +100.6% |
| 731829 – Non-threaded articles n.e.s. | 11,767 | 18,373 | +56.1% |
Washers (731822) stand out: their export price doubled over the decade, while their export volumes actually declined slightly (from 17,592 t to 13,951 t). This is consistent with EU producers shifting toward higher-specification products.
1.2 Imports grew in both volume and value, but at a slower pace
EU imports rose from €4.57 billion to €6.58 billion (+43.9%), while import volumes climbed from 1.39 million tonnes to 1.83 million tonnes (+31.6%). Unlike exports, import growth was supported by real volume increases, reflecting continued strong demand from EU industry — particularly in construction and automotive. Import unit prices rose more modestly, from €3,282/t to €3,590/t (+9.4%), indicating that importers sourced competitively priced products, especially from Asian suppliers.
The price gap between EU exports and imports widened considerably. In 2015, export prices were roughly 2.1× import prices; by 2025, the ratio had risen to approximately 2.9×. This divergence underlines the EU's increasing specialisation in higher-value fastener segments.
1.3 The trade deficit narrowed dramatically
The EU has been a net importer of steel fasteners throughout the period, but the deficit contracted substantially:
| Year | Trade balance (€) |
|---|---|
| 2015 | −€705 million |
| 2020 | −€2,700 million (trough) |
| 2022 | −€2,238 million |
| 2025 | −€778 million |
The net import reliance metric tells the same story from a different angle: it fell from 18.7% in 2015 to just 4.0% in 2025, a decline of 78.6%. The 2020 trough in the trade balance likely reflects the pandemic's disruption of EU industrial demand and supply chains, followed by a rapid export-led recovery from 2021 onward.
1.4 Domestic production expanded enormously
Available production data shows a remarkable expansion of EU manufacturing capacity:
- Production quantity: from 813,425 tonnes to 2,312,048 tonnes (+184.2%)
- Production value: from €1.95 billion to €10.10 billion (+418.9%)
The fact that production value grew far faster than production volume (implying a near-tripling of average production prices) mirrors the trade data: the EU fastener industry has scaled up while simultaneously moving toward higher-value products. This domestic capacity expansion is the principal driver behind the collapse in net import reliance.
2. Geographic Reorientation: A Shifting Map of Trading Partners
2.1 China's surge in EU imports
The most striking geographic shift in EU imports is the rise of China. Over the 2015–2025 period, EU imports from China grew from €557 million to €1.69 billion — an increase of 203.6% (top partners). China has overtaken Taiwan as the EU's largest single source of imported fasteners.
| Partner | Imports 2015 (€M) | Imports 2025 (€M) | Change |
|---|---|---|---|
| China | 557 | 1,691 | +203.6% |
| Taiwan | 1,073 | 1,225 | +14.1% |
| Türkiye | 198 | 516 | +160.5% |
| India | 250 | 314 | +25.5% |
| Vietnam | 203 | 295 | +45.8% |
| Thailand | 96 | 119 | +24.4% |
| United Kingdom | 402 | 372 | −7.3% |
China's share of total EU imports (among top partners) has thus grown dramatically. Meanwhile, Taiwan — once the dominant supplier — saw only modest growth, and the United Kingdom actually declined, likely reflecting post-Brexit trade friction. Türkiye's tripling (+160.5%) positions it as a growing alternative supplier, possibly benefiting from its customs union with the EU and geographical proximity.
2.2 The United States became the EU's primary export market
On the export side, the most significant development is the surge in EU fastener exports to the United States, which grew from €596 million to €1.15 billion (+93.7%), making the US the EU's largest export destination by 2025.
| Partner | Exports 2015 (€M) | Exports 2025 (€M) | Change |
|---|---|---|---|
| United States | 596 | 1,154 | +93.7% |
| China | 664 | 716 | +7.8% |
| United Kingdom | 575 | 629 | +9.6% |
| Switzerland | 252 | 364 | +44.5% |
| Türkiye | 204 | 331 | +62.2% |
| Mexico | 136 | 300 | +120.0% |
| Brazil | 141 | 236 | +67.1% |
Mexico (+120.0%) and Brazil (+67.1%) also saw substantial growth, pointing to a broader diversification of EU fastener exports toward the Americas. This may reflect EU producers capitalising on their quality reputation and filling gaps in markets where trade policy (e.g., anti-dumping duties on Chinese fasteners in the US) created opportunities.
2.3 Import concentration increased while export markets diversified
The Herfindahl-Hirschman Index (HHI) for import partners rose from 1,170 to 1,368 (+16.9% by value; +44.3% by volume), indicating that the EU's import supply base has become more concentrated — largely because of China's growing dominance. In contrast, the export HHI fell from 908 to 840 (−7.5% by value; −13.8% by volume), reflecting greater diversification of EU export destinations.
| Metric | 2015 | 2025 | Change |
|---|---|---|---|
| Import HHI (value) | 1,170 | 1,368 | +16.9% |
| Import HHI (volume) | 1,753 | 2,531 | +44.3% |
| Export HHI (value) | 908 | 840 | −7.5% |
| Export HHI (volume) | 886 | 763 | −13.8% |
The divergence is notable: the EU is simultaneously more exposed to concentration risk on the import side (driven by China) and more resilient on the export side through broader market access.
3. Industrial Specialisation and the Role of Core EU Economies
3.1 Germany, France, and Italy anchor the EU fastener industry
The specialisation analysis for 2025 identifies Italy and Germany as the most specialised EU economies in steel fastener production, with revealed symmetric comparative advantage (RSCA) scores of 0.29 and 0.27 respectively:
| Member State | RSCA | RCA | Production share | Trade share |
|---|---|---|---|---|
| Italy | 0.290 | 1.82 | 14.5% | 8.0% |
| Germany | 0.270 | 1.74 | 36.8% | 21.2% |
| Austria | 0.169 | 1.41 | 4.6% | 3.3% |
| Slovakia | 0.102 | 1.23 | 2.6% | 2.1% |
| France | 0.077 | 1.17 | 9.1% | 7.8% |
Germany accounts for over a third of EU fastener production and is by far the largest exporter (€2.70 billion in 2025, +34.0%) and importer (€2.00 billion, +42.4%) among EU member states. Italy's high specialisation combined with a production share of 14.5% points to a highly competitive, export-oriented fastener cluster. At the other end, Mediterranean and smaller economies (Cyprus, Malta, Greece, Luxembourg) show minimal specialisation, consistent with limited industrial base in this product category.
3.2 Polish imports surged, reflecting Central European industrial growth
Among EU importers, Poland stands out with a 125.1% increase (from €241 million to €543 million), the fastest growth of any major EU member state. This likely reflects the rapid expansion of manufacturing — particularly automotive — in Central Europe, generating strong demand for fastener inputs. Italy (+50.1%) and the Netherlands (+36.3%) also posted robust import growth, while Germany's share grew more moderately at 42.4%.
3.3 The EU is increasingly an outward-oriented fastener market
Three indicators from the autonomy and vulnerability analysis illustrate the EU's growing orientation toward external markets:
| Indicator | 2015 | 2025 | Change |
|---|---|---|---|
| Trade intensity | 48.6% | 73.7% | +51.8% |
| Export propensity | 24.3% | 57.5% | +136.9% |
| Net import reliance | 18.7% | 4.0% | −78.6% |
Export propensity more than doubled, meaning that the EU now exports a far larger share of its fastener production. Combined with the collapse in net import reliance, this signals a structural transformation: the EU fastener industry has moved from a position of moderate import dependency to one where it is a major global exporter, even while remaining a large importer in absolute terms (reflecting the sheer scale of internal demand).
Conclusion
The EU steel fastener market (CN 7318) has undergone a profound structural shift between 2015 and 2025. Three key takeaways emerge:
-
Value over volume. EU exports grew by 50% in value despite flat volumes, reflecting a decisive move up the value chain. EU producers now command unit prices nearly three times those of their import suppliers, indicating strong specialisation in high-specification fasteners.
-
Geographic realignment. China has become the dominant source of EU fastener imports (tripling its share), while the United States has emerged as the EU's primary export market. Import concentration has risen on the supply side, creating potential vulnerability, even as export markets have diversified.
-
Industrial resurgence. Domestic production expanded dramatically — in both volume (+184%) and value (+419%) — driven by Germany, Italy, and increasingly Poland. Net import reliance has fallen to just 4%, and export propensity has more than doubled, positioning the EU as a globally competitive fastener producer rather than primarily a consumer of imports.
Looking forward, the growing concentration of imports from China and the rising volatility of trade with certain partners (notably the United States with a coefficient of variation of 0.34) suggest that supply-chain resilience will remain a policy concern. The EU's strengthened production base provides a buffer, but continued investment in high-value manufacturing and diversified sourcing will be essential to sustain this competitive position.
