Udaya Exports supplies Class F Fly Ash, a pozzolanic by‑product of coal combustion, sourced from Kerala, India. The material conforms to IS 3812 and ASTM C618 specifications and is described as a low‑calcium, high‑silicon dioxide pozzolan. Each tonne is packaged in bulk sacks or shipped loose as per buyer requirement. The supplier’s listed material is suitable for use as a supplementary cementitious material.
Class F Fly Ash typically contains less than 10 % calcium oxide, 50‑60 % silicon dioxide and 20‑30 % aluminium oxide, giving it a high pozzolanic activity. In the cement industry it is valued for its ability to replace 15‑35 % of ordinary Portland cement, reducing permeability and heat of hydration. Typical physical properties include a Blaine fineness of 300‑500 m²/kg, bulk density around 0.8‑0.9 t/m³ and moisture below 1 %. These figures align with the standard ranges used in concrete mix design.
Common applications include concrete mix design, roller‑compacted concrete, brick and block manufacturing, and soil stabilisation for road works. Cement producers, ready‑mix contractors and infrastructure developers are the primary buyers. While the listing does not disclose minimum order quantity or price, interested parties should contact Udaya Exports to confirm bulk pricing, Incoterms and payment conditions. The supplier’s response rate is currently zero, so direct communication is essential to negotiate terms.

Before placing an order with Udaya Exports, importers should obtain a recent certificate of analysis confirming the Class F chemical composition, especially calcium oxide and silica levels. Requesting a sample for laboratory testing can validate pozzolanic activity and ensure compliance with IS 3812. Verify the supplier’s export licence and any environmental clearances required for shipping fly ash from Kerala. Clarifying these documents reduces the risk of non‑conforming material.
Discuss the preferred loading port, typically Cochin or nearby Kerala terminals, and agree on Incoterms such as FOB or CIF before finalising the contract. Although the listing does not disclose lead time, buyers should ask the supplier to provide an estimated shipment schedule based on current stock levels. Payment terms are commonly arranged via T/T against a signed pro‑forma invoice, but confirming the exact schedule is essential. Ensure that any bank guarantees or letters of credit meet both parties’ requirements.
Arrange a third‑party inspection at the loading point to verify bulk density, moisture content and fineness against the agreed specifications. Request accompanying documents including the material safety data sheet, test reports for loss on ignition and any applicable environmental certifications. Importers should also secure a certificate of origin and customs clearance paperwork to avoid delays at Indian ports. Maintaining a clear record of these inspections supports downstream quality control for concrete producers.
