Lump Sulphur
Also known as: Sulphur Lumps, Elemental Sulphur (Lump Form), Chemical Formula: S (Elemental Sulphur), Typical Purity: 99.5% min (often 99.8–99.9%)
Lump Sulphur is elemental sulphur produced and supplied in solid, irregular or block-like pieces (lumps). It is a common industrial and agricultural form of sulphur valued for its high purity, moisture resistance, and ease of bulk handling and storage. Compared with fine powder, lump sulphur generates less dust and is less prone to caking in humid conditions.
It serves as a primary source of sulphur for fertilizer production, sulphuric acid manufacturing, soil amendment, and various industrial processes.

Typical Physical Properties
- High moisture resistance — reduces clumping during storage and transport
- Dense and durable solid form
- Low dust generation compared with powder
- Insoluble in water (requires oxidation or further processing for plant availability)
- Good bulk handling characteristics
Key Benefits
- High purity elemental sulphur — Efficient feedstock for industrial and agricultural use.
- Excellent storage stability — Resistant to moisture absorption and caking, even in humid environments.
- Easy bulk handling and transport — Solid lump form is durable and cost-effective for large-volume shipments.
- Versatile applications — Suitable for fertilizer production, soil pH adjustment, chemical manufacturing, and other industries.
- Cost-effective — Minimal processing requirements compared with highly refined forms in some applications.
- Reduced dust — Safer and cleaner handling than fine powdered sulphur.
Recommended Applications
Agricultural & Soil Use:
- Soil amendment to lower pH in alkaline soils
- Source of elemental sulphur for conversion to plant-available sulphate (slower release than some other forms)
- Blending or further processing into sulphur-containing fertilizers
Industrial Uses:
- Production of sulphuric acid
- Rubber vulcanization
- Chemical manufacturing (sulphur compounds, dyes, etc.)
- Metallurgy, paper & pulp, and other process industries
- Raw material for fertilizer plants
Note: For direct agricultural nutrient application where rapid or uniform release is needed, granular or bentonite sulphur forms are often preferred. Lump sulphur is frequently used as feedstock or for bulk soil treatment.
Packaging Options
- 50 kg moisture-resistant bags
- 1,000 kg jumbo bags (FIBC)
- Bulk (loose) delivery by truck, rail, or vessel for industrial-scale volumes
Storage & Handling Recommendations
- Store in a cool, dry, well-ventilated area away from sources of ignition, heat, and strong oxidizers.
- Protect from prolonged moisture exposure.
- Avoid generating excessive dust; use appropriate personal protective equipment.
- Elemental sulphur is classified as a flammable solid — follow standard safety and fire-prevention guidelines.
Summary
Lump Sulphur is a high-purity, durable form of elemental sulphur ideal for industrial feedstock applications and bulk agricultural use. Its moisture resistance, ease of handling, and cost-effectiveness make it a practical choice for large-scale operations requiring reliable sulphur supply for fertilizer production, soil amendment, or chemical processing.
