About granular sulphur
Most traded sulphur is recovered from oil and gas processing and shipped as granules, which handle and store better than lump or crushed sulphur. It is the main raw material for sulphuric acid, used in turn to make phosphate fertilisers.
Large requirements are often met from more than one producer. We verify each producer separately and confirm quality by inspection at loading.
Frequently asked questions
What is granular sulphur used for?
Mainly to make sulphuric acid, most of which goes into phosphate fertiliser production. It is also used in chemicals, metals leaching and rubber.
Can you supply 50,000 tonnes or more?
Yes, including in parts from several verified producers, each inspected at loading.
How is sulphur shipped?
Usually in bulk vessels. Smaller lots can ship in big bags in containers.
