Sulphuric acid
The largest use: sulphur is burned to produce sulphuric acid for industry.
Commodity · granular sulphur
Granular sulphur, specified contract by contract.
We handle granular sulphur for industrial buyers. Grade, specification and supporting analysis documents are agreed in writing for each transaction.
About the product
Elemental sulphur is one of the most widely traded industrial raw materials. Most of it is burned to make sulphuric acid, which goes into phosphate fertilisers, metal leaching and chemical manufacturing.
Because buyers' requirements differ — by purity, moisture, ash and particle size — we do not publish a single standard grade. Each offer is tied to a written specification and the analysis documents that support it.
Where granular sulphur is used
Fertilisers
Phosphate fertiliser production and sulphur-enriched soil products.
Chemicals
Chemical processing, rubber vulcanisation and specialty chemicals.
Mining and metals
Acid leaching of copper, nickel and other ores.

Parameters agreed in every contract
These are the parameters buyers typically specify. Values are confirmed for each transaction and backed by a certificate of analysis.
| Parameter | What it describes |
|---|---|
| Purity (S, dry basis) | Share of elemental sulphur in the product |
| Moisture | Water content, affecting handling and net weight |
| Ash | Non-combustible residue after burning |
| Acidity (as H₂SO₄) | Free acid content |
| Carbon / organics | Hydrocarbon content, important for acid plants |
| As, Se, Te | Trace impurities, often limited for fertiliser use |
| Particle size | Granule size distribution and share of fines |
Documents agreed per transaction
Which documents apply, and who issues them, is set out in each contract.
- Written specification and sales contract
- Certificate of analysis
- Certificate of origin
- Independent inspection report (quality and quantity)
- Safety data sheet (SDS)
How we work
Four steps from first message to written terms.
Brief
You tell us the product or project, quantity or scope, country and timing.
Scope and specification
We clarify technical requirements, responsibilities and what is — and is not — included.
Documents and compliance
Both sides confirm identity, authority to sign and the documents the transaction needs.
Written terms
Price, specification, documents and responsibilities are set out in a signed contract.
