Market evolution: Organo-sulphur compounds (CN 2930) — 2015–2025

Introduction

This report examines the evolution of EU trade in organo-sulphur compounds (Combined Nomenclature code 2930) over the period 2015–2025. CN 2930 is a broad product category encompassing methionine, thiocarbamates, thiuram compounds, and a wide range of other organo-sulphur chemicals used in animal nutrition, agrochemicals, pharmaceuticals, and rubber processing. Over the decade, EU trade in this product class underwent a dramatic structural transformation: export volumes more than doubled while unit values fell sharply, the geographic composition of trade partners shifted substantially, and the EU's net import reliance declined markedly. Three dynamics stand out — the volume-price divergence driven by the methionine subsegment, a reorientation of trade flows toward China on the import side and emerging markets on the export side, and a significant improvement in the EU's strategic trade autonomy.

1. The Methionine-Led Volume Explosion and the Collapse of Unit Prices

Export volumes surged while values stagnated

The most striking feature of the 2015–2025 period is a massive divergence between trade volumes and trade values. EU exports in CN 2930 grew from 122,602 tonnes in 2015 to 302,683 tonnes in 2025 — an increase of 146.9% — yet their total value declined by 2.7%, from €693.9 million to €675.0 million. The average export unit price consequently collapsed by 60.6%, falling from €5,659/t to just €2,229/t. Import volumes followed a similar, though less extreme, trajectory: quantities rose 71.1% (from 147,308 t to 251,994 t) while values increased only 3.0% (from €806.6 million to €830.9 million), implying a 39.8% decline in import unit prices.

Methionine (CN 293040) is the primary driver

The product segment breakdown reveals that methionine (CN 293040) is overwhelmingly responsible for the volume-price divergence. In 2015, the EU exported only 5,734 tonnes of methionine at an average price of €6,423/t. By 2025, export volumes had surged to 194,867 tonnes — a more than thirty-fold increase — while the unit price collapsed to €578/t, a decline of over 91%. Methionine's share of total CN 2930 export volume consequently rose from 4.7% in 2015 to 64.4% in 2025. This explosion likely reflects the commissioning and ramp-up of large-scale methionine production capacity within the EU, which transformed the bloc from a marginal exporter into one of the world's leading suppliers.

Import volumes of methionine also grew strongly, from 22,981 tonnes (€108.3 million) in 2015 to 98,330 tonnes (€133.3 million) in 2025, though import prices likewise fell from €4,714/t to €1,356/t (−71.2%). This suggests that the global methionine market experienced a structural oversupply, with EU capacity expansion contributing to a worldwide price correction.

Other subsegments show more moderate trends

The residual category CN 293090 (other organo-sulphur compounds), which still accounts for 73.2% of total CN 2930 export value in 2025, saw export volumes decline slightly from 99,094 t to 91,876 t and prices fall from €6,010/t to €5,374/t (−10.6%). Import volumes in this segment grew from 104,337 t to 133,766 t, with prices declining from €6,069/t to €4,681/t (−22.9%). The thiocarbamates and dithiocarbamates segment (CN 293020) remained relatively stable in volume terms, with prices fluctuating in the €3,000–5,000/t range. Notably, the restricted precursor chemical thiodiglycol (CN 293070) and the pesticide active substances in CN 293080 both declined to near-zero trade volumes by the end of the period, likely reflecting regulatory controls and the phase-out of certain active ingredients.

2. Geographic Reorientation: China's Rise, the UK's Decline, and Emerging Export Markets

China became the dominant source of EU imports

The partner-level import data shows a pronounced shift in the EU's import geography. China's imports into the EU grew from €198.1 million in 2015 to €376.2 million in 2025, an increase of 90.0%, making it by far the largest single source of organo-sulphur imports. Conversely, Japan — formerly a major supplier — saw its exports to the EU fall by 45.2%, from €137.2 million to €75.2 million. The United Kingdom experienced the most dramatic decline: EU imports from the UK dropped by 86.0%, from €69.1 million to just €9.7 million, a decline almost certainly linked to the UK's departure from the EU Single Market and Customs Union.

Israel emerged as a growing niche supplier, with EU imports rising by 160.2% (from €10.1 million to €26.2 million), while Malaysia remained a stable but secondary source (€22.9 million to €22.1 million, −3.4%).

Import concentration intensified significantly

The Herfindahl-Hirschman Index (HHI) for EU imports by value rose from 1,628 to 2,669 (+64.0%), crossing from the "moderately concentrated" to the "highly concentrated" threshold. By volume, the import HHI followed the same trajectory, rising from 1,945 to 2,926 (+50.4%). This increasing concentration reflects the growing dominance of China as a supplier while other sources (Japan, UK, India) contracted, and it raises potential concerns about supply-chain dependency on a single country.

Export markets diversified toward Türkiye, the UAE, and India

On the export side, the picture is more balanced. The United States remained the largest single export destination throughout the period (€168.3 million in 2015, €178.1 million in 2025, +5.8%). However, several emerging markets grew rapidly: exports to Türkiye more than doubled (+113.8%, from €13.3 million to €28.3 million), exports to the United Arab Emirates more than tripled (+216.3%, from €5.8 million to €18.3 million), and exports to India rose by 29.0% (from €30.1 million to €38.8 million). Brazil remained a significant but slightly declining market (−16.0%, from €39.7 million to €33.3 million). The export HHI remained broadly stable at around 995–1,019, indicating a well-diversified export base.

Trade with Russia collapsed under sanctions

A notable geopolitical dynamic is visible in EU–Russia trade. The volatility and shock data reveals a massive price shock in EU exports to Russia in 2023 (an abnormality score of 28.0, with a price increase of 1,005.3%), followed by a near-complete supply shock in 2025 when export volumes to Russia collapsed by 99.3%. This pattern is consistent with the progressive tightening of EU sanctions following the 2022 invasion of Ukraine, which restricted chemical exports and disrupted established trade routes. Russia's trade was already characterised by high volatility (export CV of 0.70, import CV of 0.77), suggesting that even before the sanctions period, this was an erratic trading relationship.

3. Toward Greater Strategic Autonomy: The EU's Improved Trade Position

Net import reliance fell dramatically

The most consequential strategic shift over the decade was a substantial improvement in the EU's net import reliance for organo-sulphur compounds. This metric fell from 44.8% in 2015 to just 8.8% in 2025 — a decline of 80.4%. At its lowest point, it even turned negative (−17.9%), indicating that the EU temporarily became a net exporter. The trade balance moved from a deficit of €112.7 million in 2015 to a peak surplus of €13.0 million before settling at a deficit of €155.9 million in 2025. The fact that net import reliance improved so sharply despite a widening absolute deficit reflects the growth in overall EU domestic production value, which expanded faster than the trade gap.

EU production remained stable in volume but grew in value

PRODCOM production data indicates that EU domestic production of organo-sulphur compounds was remarkably stable in volume over the period, at approximately 833–837 million kg. However, production value rose by 9.3%, from €1.54 billion to €1.68 billion, suggesting a shift toward higher-value products or improved pricing within the EU manufacturing base. The export propensity — the share of domestic production that is exported — increased from 23.8% to 38.3% (+60.9%), indicating that EU producers increasingly oriented their output toward international markets. Meanwhile, trade intensity declined moderately from 62.8% to 58.3% (−7.2%), suggesting a slight reduction in the sector's overall openness relative to domestic activity.

Specialisation is concentrated in Belgium, France, and Germany

The specialisation data for 2025 reveals a clear geographic concentration of competitive advantage within the EU. Belgium has the highest revealed symmetric comparative advantage (RSCA of 0.54, RCA of 3.38), followed by France (RSCA 0.41, RCA 2.41). Together, these two countries account for roughly 47% of EU production in this sector. Germany, while having the largest absolute share of intra-EU trade (21.2%), shows only a modest comparative advantage (RSCA 0.05, RCA 1.10).

On the extra-EU export side, France's exports surged by 169.6%, from €69.3 million to €186.9 million, overtaking Germany, whose exports fell by 31.6% (from €229.0 million to €156.6 million). This shift likely reflects France's growing role as a methionine production hub. Spain also emerged as a significant exporter, with extra-EU exports nearly tripling (+188.8%, from €15.2 million to €44.0 million). On the import side, Spain's extra-EU imports also grew strongly (+88.8%, from €45.1 million to €85.1 million), and Ireland's imports nearly tripled (+191.8%, from €15.1 million to €44.1 million), while Belgium's imports fell by 47.8% (from €255.5 million to €133.3 million), possibly reflecting increased domestic production capacity.

Volatility varies sharply across partner countries

The coefficient of variation of trade values differs markedly across partners, offering insight into risk profiles. On the import side, the United States (CV 0.11) and India (0.22) are the most stable suppliers, while China (0.46), Malaysia (0.44), and Israel (0.42) show moderate volatility. The United Kingdom (0.67) and Russia (0.77) are highly volatile. On the export side, India (CV 0.13), Japan (0.16), and the United States (0.17) represent stable, low-risk markets, while Brazil (1.05) and Egypt (1.07) are highly volatile and should be treated as opportunistic rather than structural destinations.

Conclusion

Over the 2015–2025 decade, EU trade in organo-sulphur compounds (CN 2930) underwent a profound structural transformation. The most significant development was the explosive growth of methionine exports, which turned the EU from a minor player into a dominant global supplier — but at the cost of a dramatic collapse in unit prices. This volume-price divergence defined the aggregate trade statistics, masking more moderate trends in the broader organo-sulphur portfolio. Geographically, China's growing dominance as an import source and the near-disappearance of UK imports after Brexit reshaped the EU's supply landscape, while export destinations diversified toward Türkiye, the UAE, and India. Strategically, the EU's net import reliance fell from 45% to under 9%, and export propensity rose from 24% to 38%, signalling a meaningful improvement in the bloc's trade autonomy. However, the rising concentration of imports from China — reflected in the HHI increase from 1,628 to 2,669 — represents a growing dependency risk that merits close attention. Looking ahead, the balance between the EU's strengthened export competitiveness in methionine and its increasing reliance on Chinese imports for the broader organo-sulphur portfolio will be the central dynamic to watch in this sector.
