The raw material behind phosphate fertilisers. Most traded sulphur becomes sulphuric acid, and phosphate production is that acid's largest use — the desk supplies granular and formed sulphur on spot and term contracts.
Granular and formed sulphur (typically 99.5% S minimum) in bulk and big bags, sourced from producers whose standards the desk has verified. Contracted parameters typically cover sulphur purity, ash, acidity, moisture and carbon content, and the particle size of the formed product. Every parameter is fixed in the contract and verified by independent surveyors at loading and at discharge — specifications are contractual, not aspirational.
Sulphur is first of all an industrial raw material. Most of it is burned and converted to sulphuric acid, and the largest single use of that acid is phosphate fertiliser production — the acid digests phosphate rock into phosphoric acid for DAP, MAP and TSP. The rest goes to metal leaching in copper and nickel processing, to the chemical industry, and directly to agriculture as a nutrient for sulphur-deficient soils and in sulphur-enhanced fertilisers. That chain is why sulphur price moves feed straight into phosphate costs.
Formed sulphur — granules and prills — moves in bulk. Sulphur dust is combustible and wet sulphur is corrosive, so dust control, moisture limits, hold cleaning and stowage are agreed with the specification rather than left to the port. The desk arranges freight, storage and port handling end to end rather than handing logistics back to the buyer, and incoterms — FOB, CIF or CFR — are agreed with the laycan at contract stage.
Most traded sulphur is recovered from oil refining and sour-gas processing rather than mined, so supply follows hydrocarbon output: the Gulf is the largest exporting region, alongside Central Asia, North America and Asian refiners. The desk spreads origination across these sources — a spread that matters when one route tightens, as the 2026 squeeze showed when sulphur broke $1,000/t (see our market note). Price direction, freight and policy shifts that move this product are tracked in our market notes, which the desk publishes through the week.
