Market evolution: Crude sulphur (CN 2503) — 2015–2025

Introduction

This report analyses the evolution of the European Union's external trade in crude sulphur (Customs code 2503) over the decade from 2015 to 2025. The period is characterized by a profound structural shift in the market, where the EU transitioned from a significant net exporter to a net importer. This reversal was driven by a collapse in export volumes alongside a steady rise in imports, occurring amidst volatile prices and a major realignment of key trading partners. The overall trade data reveals a market undergoing a fundamental transformation.

The Great Reversal: From Trade Surplus to Deficit

The most striking feature of the decade is the complete inversion of the EU's trade balance in crude sulphur. The bloc moved from a comfortable trade surplus to a deficit, indicating a dramatic change in its competitive position and/or domestic demand-supply dynamics.

A dramatic fall in export volumes underpinned the shift

While EU export value decreased by 20.2%, the underlying driver was a 64.1% collapse in the quantity of sulphur exported, from 1.46 million tonnes in 2015 to 0.52 million tonnes in 2025. This suggests a major loss of external market share or a redirection of domestic production. The trade overview highlights that export value fell from €186 million to €148 million.

Imports surged in both volume and value

In stark contrast to exports, EU import value grew by 225.2%, reaching €196 million in 2025. Import volumes rose by 72.9% to 736,000 tonnes. This combination indicates both increased demand for sulphur within the EU and a rising unit cost for that supply, reflected in a 75.5% increase in the average import price.

The net trade balance swung from positive to negative

Consequently, the EU's net trade balance in value terms deteriorated by 137.9%, moving from a surplus of €126 million in 2015 to a deficit of €48 million in 2025. This net import reliance metric confirms the EU's new status as a net importer of the product.

A Reconfigured Supplier Landscape

The reversal in trade flows was accompanied by a complete overhaul of the EU's primary suppliers. Traditional sources dwindled in importance, while new partners, some from distant regions, rose to prominence.

Dependence on Russia and Central Asia vanished

Imports from the Russian Federation, a top supplier in 2015, fell to a negligible €167 in 2025. Similarly, trade with Uzbekistan effectively ceased. This collapse coincides with the geopolitical shifts following 2022 and indicates successful, though potentially costly, diversification of the EU's sulphur supply.

Kazakhstan, Türkiye, and the US became the new cornerstone suppliers

The void was filled by a trio of nations. Kazakhstan became the undisputed top supplier, with import values soaring by 873% to €103 million. Türkiye and the United States also saw monumental growth, with imports increasing by 494% (to €30 million) and 15,440% (to €28 million) respectively. The partner analysis shows this diversification was extensive.

The UK remained a volatile but significant supplier

Imports from the United Kingdom followed a fluctuating path but ended 433% higher at €9.5 million, maintaining its role as a consistent, if variable, regional supplier.

Export markets became more concentrated geographically

On the export side, the EU's client base shrank. Exports to Morocco, the top destination, fell by 49% to €42 million. Shipments to Brazil and Senegal collapsed by over 92%. The remaining export trade became more focused on neighbouring regions, with Türkiye and Egypt maintaining steady or slightly increased trade values. This is reflected in the top exporters report.

Rising Volatility and Geographical Specialization

The period was marked by significant price shocks and a clearer divergence in the roles of EU member states in the sulphur market.

Price shocks hit export markets, notably in 2021

A series of severe price shocks was detected, primarily affecting EU exports. The most significant event was a 152% abnormal price shift for exports to Morocco in 2021, which carried a 41.3% share of total export value. Similar price shocks impacted shipments to Türkiye and Tunisia in the same year, as detailed in the supply shocks analysis.

Member state roles became more distinct

Production data (available in kg) shows EU sulphur production rose by 76.4% in volume and 146.2% in value, suggesting increased output, likely of recovered sulphur. This production, however, did not translate into export strength. Specialization metrics reveal a stark divide: countries like Greece and Spain demonstrated high export specialization (RSCA of 0.62 and 0.49), while major economies like Sweden and Finland were highly import-oriented, indicating they are key consumption or processing hubs within the EU.

Market concentration increased on the import side

The Herfindahl-Hirschman Index (HHI) for import value rose by 35.8%, reaching 3,283 in 2025. This level indicates a highly concentrated import market, reflecting the growing dominance of a few key suppliers like Kazakhstan. In contrast, export concentration fell, aligning with the observed contraction and geographical narrowing of export markets.

Conclusion

Over the 2015-2025 decade, the EU's crude sulphur market underwent a profound structural transformation. The bloc shifted from being a major net exporter with a diversified client base to a net importer reliant on a concentrated group of new suppliers. This reversal was primarily caused by a collapse in export volumes, not by a surge in domestic demand that imports failed to meet. The supply landscape was reshaped by geopolitical events, which eliminated Russian and Central Asian sources and elevated Kazakhstan, Türkiye, and the United States to dominant positions. The market became more volatile, marked by significant price shocks, and internally, EU member states developed more specialized roles as either production-for-export hubs or import-dependent processing centers. Overall, the data points to a less competitive but more domestically integrated EU sulphur market, with increased external dependency and price volatility.
