OPC Clinker
OPC clinker supplied by Major is an ordinary Portland cement clinker, a calcium‑based mineral compound used as the primary binder in cement production. The material is offered in the standard lump form ranging from 5 mm to 25 mm and conforms to EN 197‑1 quality standards. Strength classes covered extend from 22.4 MPa to 52.5 MPa, with early strength levels of 10 MPa for normal types and above 20 MPa for rapid‑setting varieties. The clinker’s main mineral phases include C3S at 56‑60 % and CaO exceeding 60 %, matching typical OPC chemistry. Major sources the product from regions such as Turkey, Egypt and the Kingdom of Saudi Arabia, and ships it in bulk vessels for large‑scale import operations.
In the cement industry, OPC clinker is characterised by a standard bulk density of about 3.15 t / m³ and a moisture content generally below 0.5 %. Typical chemical composition comprises CaO 60‑65 %, SiO2 20‑22 %, Al2O3 5‑7 % and Fe2O3 3‑5 %, which ensures consistent performance in clinker‑based cements. These values are recognised as standard across global cement manufacturers and are used to predict reactivity, grindability and final cement strength. Major’s product aligns with these industry norms, providing a reliable feedstock for downstream blending and grinding processes.
The primary buyers of OPC clinker are cement plants that produce CEM I and CEM II cements for construction projects, infrastructure development and precast manufacturing. Importers typically arrange bulk vessel shipments and negotiate trade terms such as FOB or CIF, though specific incoterms and payment conditions must be confirmed with Major. Because the listing does not disclose minimum order quantities, lead times or pricing, prospective buyers should request these details directly to ensure the supply matches project schedules and budgetary constraints.

Sourcing OPC Clinker from Major - South Africa Import Guide
Before placing an order, importers should request a certificate of analysis that details the chemical composition, C3S and CaO percentages, as well as the EN 197‑1 compliance certificate. Verifying the bulk density and moisture content through an independent laboratory test will help ensure the material meets the performance expectations of your cement plant. These documents also support customs clearance and quality assurance processes.
Logistics for OPC clinker typically involve bulk vessel loading at the supplier’s port, with freight terms negotiated on an FOB or CIF basis. Because the listing does not specify lead times, buyers must confirm the expected shipping schedule, vessel availability and any demurrage provisions. Payment conditions such as a letter of credit or advance payment should be clarified in advance to align with your company's risk management policy.
Quality control on arrival can be reinforced by arranging third‑party inspection at the port of discharge, focusing on sampling for chemical analysis, moisture testing and visual assessment of lump size distribution. Request the packing list, material safety data sheet and any test certificates to accompany the shipment. Maintaining a clear audit trail of these documents will facilitate smooth acceptance and integration of the clinker into your production line.
