Norca Corporation offers Ordinary Portland Cement (OPC) clinkers produced from calcined limestone, containing the calcium silicates C3S, C2S, C3A and C4AF. The clinkers are sourced from Indian limestone deposits and are intended for grinding into cement at downstream plants. The supplier’s address is listed in Mumbai, Maharashtra, and it holds a harbor trust tier, indicating a higher level of platform verification.
Typical chemical composition of OPC clinkers falls within industry ranges of 55‑65% C3S, 15‑20% C2S, 5‑10% C3A and 5‑10% C4AF, which governs the strength development of the final cement. Standard fineness measured by Blaine surface area is usually 3000‑3500 cm²/g, and bulk density lies between 1.45 and 1.55 t/m³. Moisture content is kept at or below 0.5% to avoid clumping during grinding, and the clinker particle size is generally 3‑25 mm, matching conventional grinding mill feed specifications.
The primary customers are cement manufacturers who grind the clinkers into Portland cement for construction projects, infrastructure works and concrete production. Norca Corporation ships the material on FOB or CIF terms, allowing buyers to arrange bulk cargo handling at Indian ports. Importers should confirm the exact incoterm, lead‑time and any required quality certificates before finalising a purchase.

OPC Clinkers (Ordinary Portland Cement Clinkers) are the primary intermediate product used in cement manufacturing, composed mainly of calcium silicates formed by burning limestone and other raw materials at high temperatures. Indian-origin OPC clinkers are widely exported for grinding operations worldwide, particularly to Bangladesh, Sri Lanka, and African markets. They serve as the critical input for producing Portland cement used in infrastructure, construction, and concrete applications, and are traded in bulk quantities on a FOB or CIF basis.

Potential buyers should first verify the chemical composition and fineness of the clinkers by requesting a recent laboratory test report. Confirm that the supplier can provide certificates for ISO 9001 or any national quality standards that apply to cement raw materials. Checking the moisture content and sulphur levels will also ensure the product meets your downstream grinding requirements.
Logistical details must be clarified early; the supplier mentions FOB and CIF, so agree on the Indian port of loading, typically Mumbai or nearby Krishnapatnam, and the expected lead‑time, which is usually 30‑45 days for bulk orders. Payment terms are often T/T against a pro‑forma invoice, but a letter of credit can be negotiated for larger volumes. Aligning on incoterms, freight responsibilities and payment schedules helps avoid misunderstandings.
Quality assurance can be reinforced by arranging an independent third‑party inspection at the loading port. Request an inspection report that covers particle size distribution, bulk density and moisture content, as well as a certificate of analysis for each shipment. Ensure that the appropriate phytosanitary or export certificates are prepared in advance to facilitate smooth customs clearance at the destination.
