Market evolution: Sulphides and polysulphides (CN 2830) — 2015–2025

Introduction

This report examines the evolution of EU trade in sulphides and polysulphides (CN 2830) over the period 2015–2025. The product group encompasses sodium sulphides (CN 283010) as well as other sulphides and polysulphides (CN 283090), and is used across a range of industrial applications including leather processing, mining chemicals, water treatment, and the production of dyes and pharmaceuticals.

The decade tells a story of fundamental transformation. Three dynamics stand out above all: EU export values have more than doubled even as shipped volumes declined, pointing to a pronounced price-driven decoupling; the geographic structure of both imports and exports has shifted sharply, with new partners rising and traditional ones receding; and EU domestic production has contracted substantially, eroding the bloc's historically strong net-export position. Taken together, these trends suggest an industry undergoing structural adjustment under the combined pressure of rising global prices, changing competitive advantages, and evolving supply chains.

A detailed overview of the product scope and trade data is available on the Trade Dashboard — Overview.

1. Rising Prices, Falling Volumes: A Decoupled Export Trajectory

EU export values surged while volumes contracted

The most striking feature of the 2015–2025 period is the sharp divergence between the value and volume trajectories of EU exports. Over the full window:

The EU exported less product but earned significantly more revenue. The unit price tripled, rising from approximately €1,651 per tonne in 2015 to €5,392 per tonne in 2025 — the highest point in the entire window. This price acceleration was not linear: it accelerated markedly from 2021 onward, coinciding with post-pandemic supply-chain disruptions, energy cost spikes, and broader commodity inflation.

The two sub-products diverge sharply in pricing

A closer look at the product segment breakdown reveals that the two sub-headings tell very different stories on the export side:

The higher-value segment (CN 283090) accounts for the lion's share of the price increase and, consequently, the lion's share of export revenue. In 2025, CN 283090 represented €82.4M of the €90.5M total export value, while contributing only 7,760 tonnes of the 16,785 total. Sodium sulphides (283010), by contrast, moved larger volumes at far lower prices and saw their export quantity decline from 13,783 tonnes to 9,024 tonnes over the decade. The EU's export profile has thus shifted toward higher-value-added, likely more specialised sulphide products.

Import prices moved in the opposite direction

Imports tell a contrasting pricing story. While import volumes rose 86.6% (from 6,228t to 11,623t), the average import price actually declined by 11.8% (from €3,975/t to €3,504/t). This divergence is partly explained by a structural shift in import composition: cheaper sodium sulphides surged in volume (from 3,254t to 6,657t) at collapsing unit prices (€1,675/t down to €648/t), while higher-value CN 283090 imports grew more moderately and at roughly stable prices. The EU is increasingly sourcing bulk sodium sulphides from abroad at lower prices, potentially substituting for declining domestic production of that commodity.

2. Geographical Realignment: New Partners Rise as Concentration Intensifies

Import concentration more than doubled

The Herfindahl–Hirschman Index (HHI) for imports by value rose from 2,303 in 2015 to 5,049 in 2025 — an increase of 119.3%. Values above 2,500 are generally considered to indicate a moderately concentrated market; the EU's import market for sulphides has moved firmly into the highly concentrated range. This means that a smaller number of partner countries now account for a much larger share of total imports.

Bosnia and Herzegovina emerged as the dominant supplier

The driving force behind this concentration is the dramatic rise of Bosnia and Herzegovina as an import partner:

Full details are available under top partners by value.

Bosnia and Herzegovina's share of total EU imports soared from roughly one-third in 2015 to nearly two-thirds by 2025, likely reflecting the expansion of a single or very small number of producers — potentially linked to energy-intensive production relocating to lower-cost Western Balkan locations. Meanwhile, Brazil, the United States, and the United Kingdom, once significant suppliers, have all seen their shares collapse.

Export markets also shifted, with China consolidating its lead

On the export side, China grew from €8.8M to €18.6M (+110.6%) and became the EU's largest single export destination. The United States remained the second-largest market (€10.6M to €13.0M, +22.6%). However, some Latin American markets effectively disappeared: exports to Chile fell to zero (from €1.4M), and those to Peru declined by 41.9%. This geographic pruning occurred alongside a modest decrease in export concentration (HHI fell from 1,463 to 1,159), suggesting that while the EU's export base diversified slightly overall, the gains were concentrated among a handful of large markets.

Within the EU, Austria became the dominant exporter

The specialisation data for 2025 reveals a remarkable concentration of EU export capacity in Austria:

Austria's Revealed Symmetric Comparative Advantage (RSCA) of 0.91 is near the theoretical maximum of 1.0, indicating an extreme specialisation in this product. Austria went from a marginal exporter to by far the EU's largest, accounting for more than half of all EU export value by 2025. Germany remained a significant exporter but saw only modest growth, while France and Belgium also saw large percentage increases from small bases.

On the import side, Italy was the largest EU importer (€7.6M to €17.7M, +133.8%), followed by Austria (€1.3M to €11.7M, +786.5%). Finland's imports surged from negligible levels to €1.4M. Meanwhile, several traditional importing members saw sharp declines: Belgium (−84.2%), Germany (−45.4%), and Spain (−63.1%).

3. Shrinking Production and the Erosion of Net Export Supremacy

EU production volumes halved

The most consequential structural trend for the EU's long-term position in this market is the contraction of domestic production. According to PRODCOM data:

Details are available under production volumes.

Production quantity was cut in half, yet production value declined only marginally (6.2%). This implies that domestic output has shifted toward higher-value products — consistent with the export-price dynamics described in Section 1 — while lower-value production (likely bulk sodium sulphides) has migrated abroad or been discontinued. This is a classic pattern of industrial upgrading: the EU retains high-margin production while offshoring or substituting commodity-grade products.

The net export surplus narrowed substantially

The net import reliance indicator captures the EU's external trade position. A negative value means the EU is a net exporter.

The EU remains a net exporter in value terms — the trade surplus actually increased from €13.3M to €49.8M, thanks to the price-driven revenue gains described above. However, the net import reliance improved from −74.6% to −17.2%, meaning the EU's surplus relative to its total trade volume has shrunk dramatically. In other words, imports grew much faster than exports in volume terms, even as they lagged in value.

This structural shift is corroborated by the decline in export propensity (from 53.9% to 30.7%, −43.0%) and trade intensity (from 58.5% to 40.3%, −31.2%). The EU economy is becoming less reliant on international sulphides trade relative to its own production — not because trade is shrinking in absolute terms, but because the domestic market is rebalancing, with rising imports substituting for lost production capacity.

Supply-side volatility underscores emerging vulnerabilities

The volatility data highlights concentration risks in the import supply chain. Imports from China show a coefficient of variation of 0.94, while those from Canada (3.16), Madagascar (1.73), and Mexico (1.78) are extremely volatile — though at lower absolute values. The growing dependence on Bosnia and Herzegovina (a single supplier accounting for the majority of imports by value) coupled with moderate volatility (CV 0.27) represents a latent risk if production there were disrupted.

Several supply shocks were detected over the period, notably:

• A massive price shock in EU exports to Peru in 2022 (+1,848%), accounting for 1.9% of export value — though in absolute terms this is a small flow.
• A sharp import price spike from the United States in 2023 (+721%), affecting 14.8% of import value.
• A price shock in exports to Norway in 2022 (+59.3%, abnormality 34.8).

These events reflect the turbulence that swept through global chemical markets during 2022–2023, driven by the energy crisis and post-COVID supply chain disruptions.

Conclusion

The EU market for sulphides and polysulphides (CN 2830) has undergone a profound structural transformation between 2015 and 2025. The headline finding is a paradox: the EU earns far more from its exports while shipping significantly less product, a pattern driven by a tripling of unit export prices — especially in the higher-value CN 283090 segment. This price-driven revenue growth has masked a deeper story of declining domestic production (down 50% by volume), rising import dependence, and a rapidly shifting geographical landscape.

Austria's emergence as the EU's dominant exporter — growing by over 36,000% in export value — is perhaps the single most remarkable change. Meanwhile, the import market has become highly concentrated around Bosnia and Herzegovina, raising questions about supply diversification. The EU's trade surplus remains healthy in nominal terms (€49.8M in 2025), but the underlying indicators — falling export propensity, declining trade intensity, and a net import reliance moving closer to zero — suggest that the bloc is transitioning from a position of strong net export dominance to one of greater balance.

Looking ahead, the key risks are (1) over-reliance on a small number of import suppliers, (2) the sustainability of high export prices if global demand softens, and (3) the continued erosion of domestic production capacity. Conversely, the shift toward higher-value sulphide products and the consolidation of specialised production in countries such as Austria suggest that the EU's remaining role in this market is becoming more niche and more value-added — a pattern consistent with broader European deindustrialisation trends in commodity chemicals.
