More than just a rock — limestone is the backbone of industry
Limestone is one of the most widely used minerals in the world. From cement plants and steel mills to water treatment and agriculture, this calcium carbonate-rich rock is essential to global industrial infrastructure.
Pakistan is home to vast and varied limestone reserves, particularly in Punjab, Balochistan, and Khyber Pakhtunkhwa. With growing demand for raw and processed limestone, the country is increasingly being recognized by international buyers looking for consistent quality, competitive pricing, and proximity to port infrastructure.
At Shah Mercantile Co., we export bulk limestone (crushed, lump, or powdered) directly from quarries to buyers worldwide — offering full supply chain handling and quality assurance.
Global uses of limestone
- Cement production – The primary ingredient in clinker and Portland cement manufacturing
- Steel manufacturing – Acts as a flux in removing impurities during the smelting process
- Construction aggregate – Used in road building, concrete mixes, and structural fill
- Glass manufacturing – Provides calcium content and chemical stability
- Water treatment – Neutralizes acidic water and purifies industrial wastewater
- Agriculture – Used to adjust soil pH and as livestock feed filler
With its high CaCO₃ content (85% to 98%), Pakistani limestone meets specifications for both construction-grade and industrial-grade applications.
Key limestone-producing regions in Pakistan
- DG Khan, Mianwali, and Chakwal (Punjab) – Major deposits for cement-grade limestone
- Hub and Lasbela (Balochistan) – Ideal for construction aggregates and flux applications
- Swabi, Nowshera, and Kohat (KPK) – High-purity limestone used in lime and glass industries
- Margalla Hills – Well-known source of durable stone for infrastructure projects
Our network of quarries ensures consistent volume and customization for diverse industrial needs.
Why global buyers choose limestone from Pakistan
- Proximity to major ports (Karachi, Gwadar) for low-cost shipment
- Low impurity content (low MgO, Fe₂O₃) suitable for industrial refining
- Large-volume availability for long-term contracts
