Market evolution: Man-made staple fibre sewing thread (CN 5508) — 2015–2025

Introduction

This report analyses the evolution of EU external trade in sewing thread of man-made staple fibres (Combined Nomenclature code 5508) over the period 2015–2025. The product covers two sub-classes: synthetic staple-fibre sewing thread (550810), which dominates both trade flows, and artificial staple-fibre sewing thread (550820), which represents a much smaller niche. The decade was marked by a stark contraction in physical trade volumes on both sides, a dramatic reorientation of the EU from near self-sufficiency toward modest import dependence, and a sharp rise in unit values that points to structural shifts in the product mix and sourcing patterns.

1. A market in simultaneous volume contraction and price escalation

Trade volumes fell steeply on both the import and export sides

Over the 2015–2025 window, the EU's import quantity declined from 9,030 tonnes to 4,844 tonnes (−46.4%), while export quantity fell from 1,774 tonnes to 1,065 tonnes (−39.9%). Both declines are substantial and broadly parallel, suggesting that the contraction reflects a generalised reduction in the physical scale of this market rather than a one-sided shift.

Unit values rose sharply, more than compensating for volume losses on the export side

Despite the halving of export volumes, export value edged up by 4.9% to €21.2 million, implying a dramatic increase in the average export price from €11,406/t to €19,914/t (+74.6%). Import prices rose more moderately, from €4,164/t to €5,090/t (+22.2%). The growing export-to-import price ratio (from roughly 2.7× to 3.9×) indicates that the EU increasingly specialised in higher-value, more processed variants of this product while continuing to source lower-cost commodity thread from Asia.

The trade deficit narrowed dramatically as a result

The combination of resilient export values and declining import values brought the trade balance from a deficit of €17.4 million in 2015 to just €3.4 million in 2025 — an improvement of 80.2%. The deficit peaked at around €18.2 million in an intermediate year, and at one point even briefly turned positive (max +€2.4 million), underscoring the structural nature of this rebalancing.

2. A collapsing EU production base and the pivot toward higher-value exports

Domestic production of man-made staple-fibre sewing thread has all but disappeared

The most dramatic structural change is the near-total contraction of EU production. Output collapsed from 12,123 tonnes to 2,400 tonnes in quantity (−80.2%) and from €201 million to €32 million in value (−84.1%). This is far steeper than the decline in trade volumes, indicating that the EU's sewing-thread industry has undergone a profound contraction, likely driven by offshoring, competitive pressure from Asian producers, and consolidation.

Yet a handful of Member States retain specialised export capacity

Despite the production collapse, specialisation data for 2025 shows that Romania (RSCA 0.81, RCA 9.4), Portugal (RSCA 0.54, RCA 3.3), and Czechia (RSCA 0.51, RCA 3.1) maintain significant comparative advantages in this product. These countries likely host the remaining high-value production niches — consistent with the high and rising average export price. By contrast, Ireland, Luxembourg, Slovakia, Finland, and Sweden show near-zero specialisation, confirming that production is highly geographically concentrated within the EU.

France and Germany emerged as the leading EU exporters by value

The top EU exporting Member States shifted notably over the period. France saw the most dramatic increase, rising from €1.6 million to €4.6 million (+190.8%), while Germany grew from €4.0 million to €5.9 million (+46.8%). Italy, once the largest exporter at €4.7 million, contracted to €2.3 million (−51.7%). This redistribution likely reflects the move toward higher-value, specialised thread products centred on Western European brands and production know-how.

Export concentration declined, indicating a diversification of destinations

The Herfindahl-Hirschman Index for exports by value fell from 985 to 770 (−21.8%), indicating that EU exports became less concentrated among a few destinations. This is partly explained by the sharp decline in exports to Russia (from €2.8 million to €0.5 million, −82.1%), which was likely disrupted by sanctions following 2022, while other markets such as Türkiye (+57.8%), Ukraine (+31.2%), and Serbia (+32.4%) absorbed some of the redirected flows.

3. China's dominance in EU imports eroded but remains formidable, amid moderate supplier diversification

China remains the overwhelmingly dominant supplier but lost significant share

China was by far the largest source of EU imports throughout the period, accounting for roughly 70% of import value in 2015. However, Chinese shipments to the EU declined from €26.3 million to €15.6 million (−40.7%). This absolute decline is the single most important driver of the overall contraction in EU imports.

Türkiye bucked the trend and consolidated its position as the second-largest supplier

While nearly all other major suppliers saw steep declines, EU imports from Türkiye actually grew from €5.9 million to €6.6 million (+10.7%). Türkiye's proximity, customs-union arrangements with the EU, and established textile industry make it a natural near-shoring alternative to Asian suppliers — a pattern consistent with broader post-pandemic supply-chain reshoring trends.

Import concentration by value declined modestly

The import HHI by value fell from 5,166 to 4,745 (−8.1%). While still highly concentrated — reflecting China's dominant role — the decline signals a gradual diversification of sourcing. Notably, the HHI by volume rose slightly (+11.1%), suggesting that the diversification was more visible in value terms (i.e., some higher-price alternative suppliers gained ground) than in pure tonnage.

Price shocks were isolated but significant

Two notable price shocks were detected during the period. An Indonesian supply experienced a sharp price spike in 2022 (+25.1% shift, abnormality score 10.2), coinciding with post-pandemic raw-material cost pressures. A more moderate Chinese price shock occurred in 2023 (+10.9%, abnormality 2.1). Given China's 93.9% share in that year's import value, even modest price movements there have outsized effects on the EU's total import bill.

Conclusion

The EU market for man-made staple-fibre sewing thread (CN 5508) underwent a profound transformation between 2015 and 2025. Domestic production collapsed by over 80%, the EU's net import reliance shifted from a slight surplus (−1.8%) to a modest deficit (+6.1%), and both import and export volumes contracted sharply. Yet the story is not one of simple decline: the EU pivoted toward higher-value exports (with unit prices rising 75%), diversified its export destinations, and saw its trade deficit narrow by 80%. China's dominance as a supplier, while diminished in absolute terms, remained structurally intact. Türkiye emerged as a relative winner among import sources, benefiting from near-shoring dynamics. The key strategic question going forward is whether the EU's remaining specialised production base — concentrated in Romania, Portugal, and Czechia — can sustain its competitive edge in premium product segments as the broader commodity market continues to migrate offshore.
