Market evolution: Modified starches and dextrins (CN 3505) — 2015–2025

Introduction

This report analyses the EU's external trade in CN 3505 — a category covering dextrins and other modified starches, as well as starch-based glues — over the period 2015–2025. The product group is bundled under two sub-headings: 350510 (dextrins and modified starches, including pregelatinised, esterified, or etherified variants) and 350520 (starch-based glues not packaged for retail). These products serve a wide range of industrial applications, from food processing and paper-making to adhesives and textiles.

The decade under review witnessed profound structural shifts: a global pandemic, the energy-price spike of 2022, the post-Brexit reconfiguration of UK–EU supply chains, and the sanctions regime following Russia's invasion of Ukraine. Against this backdrop, the EU's modified-starch sector proved remarkably resilient — not only sustaining its strong net-exporter position but actually reinforcing it, even as volumes traded externally declined. The story that emerges is one of value creation outpacing physical output, significant geopolitical reshuffling of trade partners, and a consolidation of the EU's competitive specialisation in this product space.

1. A market defined by rising values and falling volumes: the price-inflation era

1.1 Export value surged while tonnage contracted

The most striking feature of the 2015–2025 period is the persistent divergence between the monetary value of EU exports and the physical volumes shipped. Total EU exports of CN 3505 goods rose from €624.2 million in 2015 to €858.1 million in 2025, a gain of 37.5%. Over the same period, exported tonnage fell from 681,102 tonnes to 596,296 tonnes, a decline of 12.5%. The reconciliation lies in unit prices, which climbed from €916/t to €1,439/t — an increase of 57.0%.

This pattern — more euros per tonne, fewer tonnes overall — reflects the combined impact of input-cost inflation (energy, raw starch feedstocks), a shift toward higher-value specialty modified starches, and the post-2021 commodity super-cycle that lifted prices across the entire starch-derivatives value chain.

1.2 Import trends mirrored the same price-driven dynamics

EU imports followed a comparable trajectory, though on a much smaller scale. Import value rose 19.6% (from €112.7 million to €134.8 million) while volumes edged down 4.1% (from 90,667 to 86,911 tonnes). Import unit prices climbed 24.7%, from €1,243/t to €1,551/t — meaning that import prices consistently exceeded export prices throughout the period. This premium likely reflects the EU's tendency to import specialised, higher-cost modified starches (e.g., from the United States and Japan) while exporting more commoditised grades in bulk.

1.3 The trade balance widened substantially

Because export growth outpaced import growth in value terms while both sides saw volume softness, the EU's trade surplus in CN 3505 expanded from €511.4 million in 2015 to €723.3 million in 2025 — an increase of 41.4%. The net import reliance ratio deepened from −19.6% to −48.0%, confirming that the EU's net-exporter status not only persisted but intensified dramatically. In simple terms, the EU's production base grew faster than its domestic consumption, pushing an ever-larger share of output onto world markets.

1.4 EU production grew in value but barely in volume

The production data confirms this inflation-driven narrative. Domestic production quantity rose only 5.9% over the decade (from 1.846 billion kg to 1.956 billion kg), yet production value more than doubled — up 107.9% from €1.12 billion to €2.33 billion. The near-doubling of the production-value-to-output ratio underscores that the sector's headline growth was overwhelmingly a price phenomenon rather than a volume story. This is consistent with the broader European manufacturing experience of the early 2020s, where energy costs, wage pressures, and supply-chain disruptions transmitted through to higher selling prices.

2. Geopolitical upheaval reshaped trade partner geography

2.1 The collapse of exports to Russia

Perhaps the single most dramatic trade-shift in the dataset is the near-total evaporation of EU exports to the Russian Federation. In 2015, Russia was the EU's fourth-largest extra-EU export destination for CN 3505, absorbing €51.7 million worth of product. By 2025, this figure had collapsed to just €1.7 million — a decline of 96.6%. The timing aligns precisely with the sanctions imposed following the full-scale invasion of Ukraine in February 2022; the coefficient of variation for this corridor (0.70) is among the highest for any export partner, reflecting extreme instability in the later years of the period.

The loss of the Russian market required EU exporters to find alternative outlets. As we shall see, much of this redirection appears to have been absorbed by growth in other Asian and Middle Eastern markets, as well as by deepening penetration in traditional partners such as the United States and Japan.

2.2 Post-Brexit recalibration with the United Kingdom

The United Kingdom remained the EU's single largest export partner throughout the period, with exports growing 45.3% from €88.7 million to €129.0 million. However, this growth was volatile — the UK market peaked at €195.0 million before settling back, and the relationship's coefficient of variation (0.05) conceals a sharp intra-period dip around Brexit implementation (2019–2021).

On the import side, the picture is more sobering. UK-sourced imports into the EU fell from €42.5 million in 2015 to €23.2 million in 2025, a decline of 45.4%. The UK went from being the EU's top import source to third place, overtaken by the United States. This likely reflects the re-establishment of customs barriers and rules-of-origin requirements that made intra-European supply chains involving UK intermediaries less efficient post-Brexit.

2.3 Emerging suppliers: Ukraine, Türkiye, and China surge into the EU market

Three countries experienced extraordinary growth as import sources for the EU:

Ukraine's rise is especially noteworthy. From virtually zero trade in 2015, Ukraine became a significant supplier by 2025 (€10.3 million). This likely reflects the EU–Ukraine Deep and Comprehensive Free Trade Area (DCFTA) entering into force in 2016 and the EU's post-2022 policy of facilitating Ukrainian agricultural exports as part of solidarity measures during the war. However, the high volatility (CV = 0.88) and the peak-and-trough pattern (imports reached €21.8 million before retreating) suggest the relationship remains fragile.

Türkiye similarly grew from a negligible base (€0.7 million) to over €10 million, with the coefficient of variation (0.93) indicating highly erratic flows. A price shock in 2022 — with an abnormality score of 55.7 and a unit-price shift of +48.5% — stands out as the most extreme supply-side disruption detected in the dataset, possibly linked to the Turkish lira's depreciation and the pass-through of global energy costs.

China's growth (+522%) was steadier (CV = 0.48), reflecting its established role as a large-scale producer of modified starches, particularly for industrial applications.

2.4 Stable high-value export partners: the US, Japan, and South Korea

While Russia collapsed and new markets emerged, the EU's core extra-EU export relationships with the United States, Japan, and South Korea proved both stable and growth-oriented:

South Korea nearly doubled its intake of EU CN 3505 products, growing from €21.5 million to €42.9 million. These three markets collectively represent a stable, high-value core that compensated for the loss of Russia and provided a reliable base for EU exporters. The low coefficients of variation (all below 0.16) underscore the predictability of these trade flows — a quality prized by supply-chain planners.

3. EU market structure consolidated: specialisation deepened and partner concentration fell

3.1 The Netherlands and Germany anchored the EU's export platform

The EU's export base for CN 3505 is heavily concentrated in a handful of Member States. In 2025, the top three exporters were:

The Netherlands alone accounted for roughly one-third of all EU extra-EU exports in value terms. Its dominance is underpinned by a strong revealed comparative advantage (RCA of 2.20) and a normalised RCA (RSCA) of 0.37 — the second-highest in the EU after Lithuania. The Netherlands' position reflects its large starch-processing industry (rooted in its abundant potato and wheat production), its deep-water port infrastructure facilitating re-export, and the presence of major agro-industrial multinationals.

Belgium recorded the fastest growth among major exporters, with exports surging 178.4% from €17.5 million to €48.8 million — potentially benefiting from its position as a logistics gateway and from capacity investments by starch processors in Flanders.

3.2 Import concentration decreased sharply — diversification underway

One of the most significant structural changes visible in the data is the sharp decline in import concentration. The Herfindahl-Hirschman Index (HHI) for imports by value fell from 2,664 in 2015 to 1,473 in 2025 — a decline of 44.7%. This places the import market firmly in the "moderately concentrated" range by standard competition benchmarks (below 2,500), compared to the "highly concentrated" range at the start of the period.

The diversification is explained by the simultaneous decline of the UK as a source (from the dominant supplier to one of several) and the rise of Ukraine, Türkiye, China, and Serbia as alternative suppliers. No single country now commands the kind of import share that the UK once held, meaning the EU's supply base for modified starches is structurally less vulnerable to disruption from any one partner.

Export-side concentration also declined, but more modestly: the export HHI fell from 724 to 570 (−21.2%), remaining well below the import HHI. This indicates that EU exports were already diversified at the outset and became only slightly more so.

3.3 The 350510 sub-product dominated, but 350520 imports grew faster

Breaking down the product into its two sub-headings, modified starches and dextrins (350510) accounted for the overwhelming majority of both imports and exports. However, starch-based glues (350520) grew much faster on the import side:

Imports of starch-based glues (350520) more than quadrupled in volume and quintupled in value over the decade. While the absolute numbers remain small (14,174 tonnes and €13.8 million in 2025), the trajectory suggests growing EU demand for imported adhesive products, possibly driven by packaging and construction applications.

On the export side, the two sub-products diverged in tonnage: 350510 export volumes fell 16.2% while 350520 volumes rose 42.8%. This suggests that the EU's competitive advantage in starch-based glues (for non-retail use) may be strengthening, even as the more commoditised modified-starch segment faces volume headwinds.

3.4 Detected price shocks point to 2022 as the stress-test year

The volatility analysis identified three significant price shocks:

Two of the three shocks centred on 2022, consistent with the global energy crisis and the war-related disruptions to grain and starch supply chains. The Türkiye import shock — the most extreme in the dataset with an abnormality score of 55.7 — likely reflects a combination of the lira's depreciation (raising euro-denominated prices) and Turkey's own inflation crisis. The US export price shock (abnormality 9.8) affected the EU's single most valuable export corridor by price, with the 11.8% value share indicating its systemic importance.

Conclusion

The EU's modified-starch and dextrin market (CN 3505) underwent a decade of transformation between 2015 and 2025. Three themes define the period:

1. Price-driven growth replaced volume expansion. Export values rose 37.5% while tonnage fell 12.5%; production values doubled while output barely grew. The EU's starch-derivatives industry became more profitable per unit, but did not materially expand its physical footprint.

2. Geopolitics rewrote the partner map. Russia virtually disappeared as an export destination (−96.6%), the UK's role as an import source halved post-Brexit, and three new import suppliers — Ukraine, Türkiye, and China — surged from near-zero to collectively over €30 million. Meanwhile, the US, Japan, and South Korea provided stable, high-value demand for EU exports.

3. The EU consolidated its net-exporter status and diversified its supply base. The trade surplus grew 41.4%, net import reliance deepened to −48%, and import-source concentration (HHI) fell by 45%. The EU entered the second half of the 2020s with a structurally stronger, more diversified, and more specialised position in global modified-starch trade than it held at the start of the period.

Looking ahead, the key risks to monitor include the sustainability of the price-driven value growth as inflation moderates, the stability of trade corridors with Ukraine and Türkiye (both characterised by high volatility), and the competitive challenge posed by Chinese producers whose EU market share has grown fivefold in a decade.
