Market evolution: Synthetic filament tow (CN 5501) — 2015–2025

Introduction

Synthetic filament tow (CN 5501) covers continuous synthetic filaments destined for cutting into staple fibres, spanning acrylic, polyester, polyamide, polypropylene, aramid and other polymer types. Over the 2015–2025 period, the EU's position in global trade of this product has undergone a fundamental transformation: the Union shifted from being a significant net exporter — with a trade surplus of €154.1 million in 2015 — to a net importer, posting a deficit of €27.1 million in 2025. This reversal was driven primarily by a dramatic collapse in exports (–90.1% in value), while imports proved comparatively resilient (–7.7%). Meanwhile, EU domestic production actually grew over the same period, creating a complex picture of structural realignment in the European man-made fibres industry.

1. The Collapse of EU Exports: From Dominant Supplier to Marginal Player

EU export volumes and values fell by approximately 90% in a single decade

The most striking feature of the 2015–2025 period is the near-total evaporation of EU exports of synthetic filament tow. As the general overview shows, the EU exported 94,380 tonnes worth €205.5 million in 2015; by 2025, these figures had fallen to 7,625 tonnes and €20.3 million respectively — declines of –91.9% in volume and –90.1% in value.

The decline was not linear. Exports actually peaked in volume around 2018 (101,884 t) before entering a steep and sustained decline, accelerated by the COVID-19 shock in 2020 and continuing thereafter. Unit prices fluctuated between €1,731/t and €3,440/t over the period, but the price increase of +22.3% over the full period was far too modest to compensate for the volume collapse.

The acrylic/modacrylic segment (CN 550130) drove the export decline

The product segment breakdown reveals that the decline was overwhelmingly concentrated in acrylic and modacrylic filament tow (CN 550130), which is by far the largest sub-segment:

Acrylic tow accounted for the lion's share of EU exports at the start of the period and remained dominant even as volumes shrank. Polyester and polypropylene exports were already marginal in 2015 and effectively disappeared. Aramid and nylon sub-segments (CN 550111 and 550119) only appear in the data from 2022, suggesting either reclassification or the emergence of small niche flows.

Traditional export markets in Türkiye, South Asia and the US were lost

The country-level export data shows that the EU lost virtually all of its major third-country markets:

Türkiye was the single largest market (€55.8M in 2015) and saw the largest absolute decline. South Asian destinations (India, Bangladesh, Pakistan) — which are major textile-manufacturing hubs — collectively lost €34.9M in EU export sales. The United States, the second-largest market in 2015, saw its imports of EU filament tow fall to just €0.3M. The United Kingdom, while still a destination, also shrank by 77.4%.

Germany, Portugal and Spain bore the brunt of the export contraction

Among EU Member States, Germany was by far the largest exporter in 2015 (€133.2M) but saw a –96.4% decline to €4.8M by 2025. Portugal, the second-largest exporter (€45.7M → €9.6M, –79.0%), and Spain (€10.5M → €0.2M, –97.8%) suffered similarly. The specialisation data shows that Spain (RSCA = 0.75) and Portugal (RSCA = 0.69) still display revealed comparative advantage in this product in 2025, but their absolute export volumes have dwindled.

2. Import Resilience and a Diversifying Supplier Base

EU imports declined moderately, with volumes down by a third but values more stable

Unlike exports, EU imports held up comparatively well. Import values fell only 7.7% (from €51.4M to €47.4M), while volumes declined 32.3% (from 23,409 t to 15,850 t). The gap between these two figures is explained by rising import prices: the average unit price climbed from €2,195/t to €2,991/t (+36.2%).

Notably, import volumes remained relatively stable between 2015 and 2018, then dipped during 2019–2020 (likely COVID-related), recovered strongly in 2022–2024, and then fell again in 2025. The 2022 peak in import value (€79.3M) partly reflects elevated global prices that year.

Türkiye remained the dominant supplier while Mexico and the US gained ground

The partner-country data for imports shows a noteworthy reshuffling:

Türkiye remained the largest single supplier but saw its share erode. The most dynamic growth came from the United States (+162.2%) and Mexico (+91.3%), which together supplied €20.7M in 2025, up from €9.3M in 2015. Meanwhile, Belarus — once the fourth-largest supplier — collapsed from €7.6M to €0.6M (–92.3%), likely reflecting the impact of EU sanctions imposed after 2022. The United Kingdom also saw reduced sales to the EU, consistent with post-Brexit trade frictions.

Import concentration (HHI by value) fell from 2,642 to 2,120 (–19.8%), indicating a gradual diversification of the supplier base. Volume-based HHI followed a similar trend (3,084 → 2,659, –13.8%).

Acrylic/modacrylic tow (CN 550130) remained the dominant import category

On the import side, acrylic and modacrylic tow (CN 550130) accounted for the majority of volumes throughout the period:

While acrylic tow declined in absolute terms (–33.2% in volume), it remained the backbone of EU imports. The "other synthetics" segment (CN 550190) nearly doubled in volume and more than doubled in value, suggesting growing demand for specialty filaments. The appearance of aramid (CN 550111) and nylon (CN 550119) flows from 2022 onward — commanding high unit prices (€17,340/t and €3,214/t respectively in 2025) — points to niche but high-value import needs.

Import price shocks were detected for the United States and China

The volatility analysis detected three significant shock events:

1. US imports — price shock in 2022 (abnormality score: 43.4, +37.2% price shift): The largest detected shock coincided with the post-pandemic energy cost surge and global supply-chain disruptions, which hit the US-origin filament tow supply chain particularly hard.

2. China exports — price shock in 2021 (abnormality: 9.9, +82.4% price shift): EU exports to China saw an extraordinary price spike, possibly reflecting a temporary supply shortage or quality-mix change.

3. China imports — price shock in 2019 (abnormality: 8.2, +101.1% price shift): Import prices from China more than doubled in a single year, potentially linked to pre-pandemic trade tensions or shifts in the Chinese domestic market.

Among import partners, Japan showed the highest volatility (coefficient of variation: 0.99), followed by Belarus (0.72), while Türkiye was the most stable supplier (CV: 0.24). On the export side, China showed the highest volatility (CV: 1.32) among destinations.

3. A Structural Paradox: Rising Production Alongside Growing Import Dependence

EU domestic production grew substantially even as trade flows contracted

One of the most revealing findings is that EU production of synthetic filament tow increased markedly between 2015 and 2025:

Production volume grew by 44.5% and production value more than doubled, implying a substantial increase in the average value per kilogram produced. This suggests a shift toward higher-value, more specialised filament types within the EU. The fact that production grew while exports collapsed implies that the additional output was absorbed by intra-EU demand (the data covers only extra-EU trade) and/or by downstream domestic textile and nonwoven industries.

The EU transitioned from slight self-sufficiency to substantial import reliance

The net import reliance indicator captures the structural shift most starkly:

In 2015, the EU was a marginal net exporter of filament tow (net import reliance of –1.6%). By 2025, the Union had become a significant net importer (44.3%). Trade intensity — the ratio of trade (imports + exports) to production — surged from 14.9% to 63.2%, meaning the EU's filament tow sector became far more exposed to international markets. Export propensity (exports as a share of production) also rose from 8.8% to 24.8%, though this reflects the denominator (production) growing while exports shrank — it is driven by the relatively smaller decline in production compared to the collapse of exports.

The production increase likely reflects a reorientation toward intra-EU and specialty markets

The simultaneous rise in production and decline in extra-EU exports points to a structural reorientation of the European filament tow industry. Several factors may explain this:

• Vertical integration: EU producers may have increasingly channelled their tow output into their own downstream staple fibre and nonwoven operations rather than selling filament tow as a commodity on the world market.
• Product mix shift: The near-doubling of production value (+114.5%) against a more modest volume increase (+44.5%) suggests a move toward higher-margin, more specialised products (e.g., aramids, high-performance polyesters) that are either consumed within the EU or exported at the finished-product stage.
• Loss of cost competitiveness in commodity segments: Acrylic tow, the dominant export commodity, faced intensifying competition from Asian and Turkish producers. EU manufacturers may have ceded the commodity export market while retaining domestic market share through quality, logistics advantages or customer relationships.

Conclusion

The EU's trade in synthetic filament tow (CN 5501) underwent a dramatic structural transformation between 2015 and 2025. The most visible change was the collapse of exports — down approximately 90% in both value and volume — which converted the EU from a net exporter (surplus of €154M) into a net importer (deficit of €27M). This export decline was concentrated in the acrylic/modacrylic sub-segment (CN 550130) and affected virtually all major destination markets, with Türkiye, the United States, India and Bangladesh recording the steepest falls.

Imports proved considerably more resilient, declining only modestly in value terms. The supplier base diversified, with the United States and Mexico gaining share while Belarus and the United Kingdom lost ground. Import prices rose by 36%, reflecting broader inflationary trends and a shift toward higher-value product types.

Paradoxically, EU domestic production of synthetic filament tow grew by 44.5% in volume and 114.5% in value over the same period, suggesting a fundamental reorientation of the European industry toward higher-value products, intra-EU circulation and downstream integration. The result is an EU filament tow sector that is simultaneously larger in production terms, more trade-intensive, and structurally dependent on imports for the commodity segments it once exported at scale. Going forward, monitoring the balance between rising import reliance and the EU's evolving production profile will be essential for assessing the sector's resilience to supply disruptions and price shocks.
