Market evolution: Synthetic monofilament strip (CN 5404) — 2015–2025

Introduction

This report examines the evolution of EU trade in synthetic monofilament and strip products classified under CN 5404 over the period 2015–2025. This heading encompasses synthetic monofilament of ≥ 67 decitex (including elastomeric, polypropylene, and other variants) as well as narrow synthetic strip and artificial straw of ≤ 5 mm width. The analysis covers trade flows with non-EU countries, production trends, partner concentration, and market volatility. Over the decade, the EU has maintained a structural trade surplus in this product category, but the balance has narrowed considerably as import volumes surged while export volumes declined.

A Shrinking Surplus: Volume Shifts and the Import–Export Divergence

Export volumes have contracted while import volumes have expanded substantially

The most striking macro-level trend is the divergent trajectory of EU export and import volumes. Over the 2015–2025 period, EU exports fell from 44,491 tonnes to 34,676 tonnes (–22.1%), while imports grew from 30,369 tonnes to 44,877 tonnes (+47.8%). By 2025, import volumes actually surpassed export volumes — a reversal of the pattern observed at the start of the period.

Rising export prices have cushioned the value impact, but the surplus has halved

Despite the decline in export volumes, export value remained virtually flat (–0.1%) because unit export prices rose from €5,484/t to €7,026/t (+28.1%). Conversely, import prices fell from €4,991/t to €4,341/t (–13.0%), suggesting that the EU has increasingly sourced from lower-cost suppliers. The result is that the trade surplus shrank by 47.2%, from €92.4 million to €48.8 million. In some intermediate years (notably 2020 and 2022), the surplus dipped even further, reaching a low of approximately €36.1 million.

Domestic production has declined in volume while maintaining value

EU production volumes fell from 107,473 tonnes in 2015 to 91,000 tonnes in 2025 (–15.3%), mirroring the decline in exports. However, production value edged up from €411.9 million to €420.0 million (+2.0%), indicating that EU producers have shifted toward higher-value segments. This is consistent with the rising export unit values, suggesting a move upmarket in EU manufacturing.

Geographic Reorientation: New Supplier Corridors and Shifting Export Destinations

Middle Eastern and Southeast Asian suppliers have gained prominence in EU imports

The partner composition of EU imports has undergone significant reshuffling. The United Arab Emirates remained the largest single supplier, growing from €47.1 million to €56.1 million (+19.0%). However, the most dramatic changes occurred among newer suppliers:

Viet Nam and Saudi Arabia stand out as the most remarkable emerging suppliers. Viet Nam's rise from virtually zero to €15.8 million in EU-bound exports is indicative of the broader Southeast Asian manufacturing boom in synthetic textiles. Saudi Arabia's similarly explosive growth likely reflects downstream petrochemical investments in polymer processing. Meanwhile, imports from the United Kingdom declined by 48.1%, partly attributable to post-Brexit trade friction.

EU exports have pivoted toward Türkiye while traditional markets soften

On the export side, the most notable development is the doubling of exports to Türkiye, which grew from €14.1 million to €29.3 million (+108.1%) and became the fourth-largest destination by 2025. This likely reflects Türkiye's expanding textile and industrial manufacturing base. Exports to China also grew modestly (+12.8% to €54.2 million), suggesting sustained demand for EU-origin specialty monofilament.

The decline in exports to the United Kingdom (–26.7%) again aligns with post-Brexit effects, while the reduction in US-bound exports (–8.1%) may reflect increasing competition from Asian producers in that market.

Germany dominates EU exports; import sourcing is more fragmented

Among EU Member States, Germany is by far the largest exporter of CN 5404 products, with exports rising from €141.4 million to €169.3 million (+19.7%) — accounting for roughly 69% of EU extra-EU exports by 2025. Italy and the Netherlands follow at much lower levels, with the Netherlands experiencing a steep decline (–58.6%). On the import side, Belgium, Germany, and Italy are the largest recipients, with Spain (+99.6%) and Ireland (+257.6%) showing the strongest growth in import demand over the period. The Herfindahl-Hirschman Index for import partners fell from 1,701 to 1,443 (–15.1%), confirming a diversification of supply sources, while export concentration edged up slightly (+4.2%).

Volatility, Shocks, and the Product Mix: Understanding the Underlying Fragility

Price volatility varies widely across trading partners

The coefficient of variation of import flows reveals that some newer suppliers carry significantly higher price volatility than established ones. Viet Nam (CV = 0.98) and India (CV = 0.99) exhibit very high volatility, while the UAE (CV = 0.10) and Japan (CV = 0.08) are among the most stable suppliers. On the export side, shipments to Russia (CV = 0.63) and Morocco (CV = 0.50) show the most pronounced fluctuations.

Several notable supply shocks punctuated the decade

The shock detection identifies three major abnormal events during the period:

The Viet Nam import price shock in 2017, with a 645% price shift, likely reflects the entry of a new supplier with initially high unit values or a market correction following the rapid volume expansion from that origin. The Türkiye export price doubling in 2020 coincides with the COVID-19 pandemic, which disrupted global supply chains and may have created temporary pricing dislocations in EU–Türkiye trade flows.

The product mix reveals a concentration in "other synthetic monofilament" and strip products

Looking at the sub-product breakdown, the two largest segments dominate both trade flows:

• 540490 (Strip and artificial straw): This is the largest import segment by volume (34,895 tonnes in 2025, worth €103.9 million), used extensively in packaging, agriculture, and decorative applications.
• 540419 (Other synthetic monofilament, excl. elastomers and polypropylene): This dominates exports (14,498 tonnes in 2025, worth €160.0 million) and commands the highest unit prices among the main sub-products, reflecting its use in technical and industrial applications.
• 540412 (Polypropylene monofilament) and 540411 (Elastomeric monofilament) are smaller segments but have shown divergent trends: PP monofilament imports grew in volume (+125% from 2015 to 2025), while elastomeric monofilament exports have declined sharply in recent years.

Conclusion

Over the 2015–2025 decade, the EU's trade in synthetic monofilament and strip (CN 5404) has undergone a fundamental rebalancing. While the Union retains a trade surplus, it has shrunk by nearly half as import volumes surged (+47.8%) and export volumes contracted (–22.1%). EU producers appear to have responded by moving upmarket: production value has held steady despite falling volumes, and export unit prices have risen by 28%.

Geographically, the import landscape has diversified significantly, with Viet Nam, Saudi Arabia, and Türkiye emerging as major new or expanded suppliers, while the United Kingdom's role has diminished post-Brexit. On the export side, Türkiye has become a critical growth market, and Germany's dominance as the EU's primary exporter has strengthened. The volatility analysis underscores that these newer trading relationships — particularly with Viet Nam and India — carry higher price instability, and several significant supply shocks have punctuated the period.

Looking ahead, the EU's declining production volumes, growing import reliance, and the increasing importance of politically or economically volatile supplier origins present a structural vulnerability that warrants monitoring. The shift toward higher-value production is a positive development, but it has not been sufficient to offset the volume-driven erosion of the trade surplus.
