Product overview
A foundational input for agriculture, chemicals and heavy industry
Sulphur is used across fertilizer production, chemical manufacturing and rubber vulcanization. It supports soil acidification, sulphuric acid production and the strengthening of rubber products.
Sulphur lumps are raw, irregular solid chunks. They suit cost-sensitive, large-scale operations equipped with on-site crushing or melting systems.
High purity and low moisture are important because contaminants and excess water can affect downstream reactions and product quality. Our 99.5% minimum grade provides a dependable input for demanding industrial applications.

Product comparison
How sulphur lumps differ from granular sulphur
The best format depends on your handling system, processing equipment and need for uniformity.
Granular sulphur
- Uniform, spherical pellets
- Free-flowing with lower dust
- Predictable controlled melting
- Preferred where precision and uniformity are critical
Typical specification
High purity with low moisture and ash
The following values represent our standard sulphur lumps. Specific process requirements can also be discussed.
| Parameter | Typical value |
|---|---|
| Sulphur | 99.5% Min |
| Moisture | 0.5% Max |
| Ash | 0.2% Max |
| Size | 10–50 mm |
| Packing | Bulk in Vessel |
Key applications
High-purity sulphur for four major industrial uses
Select an application to see how sulphur lumps support each process.
Fertilizer production
Sulphur is converted into sulphuric acid for phosphate fertilizer manufacturing and is also used directly as a soil amendment in alkaline soils.
- Sulphuric acid feedstock
- Soil pH correction
- Correction of crop sulphur deficiency
Chemical manufacturing
Sulphur is the main raw material for sulphuric acid, which feeds a broad range of chemical intermediates and industrial processes.
- Sulphuric acid production
- Chemical intermediate manufacturing
- Controlled purity for sensitive reactions
Rubber vulcanization
Sulphur cross-links rubber polymers to improve elasticity, strength and durability, transforming raw rubber into stable, hard-wearing material.
- Improved elasticity
- Greater mechanical strength
- Consistent batch-to-batch vulcanization
Industrial processing
Sulphur lumps suit large-scale operations equipped to crush or melt material on site, making them practical for cost-sensitive supply chains.
- On-site crushing and melting
- Competitive input cost
- Large-scale bulk handling
