G.I. supplies Class F fly ash that conforms to ASTM C618 specifications and is produced from the combustion of siliceous or siliceous‑aluminous coal. The material is described as a high‑pozzolanic additive that reacts with calcium hydroxide in cement to develop cementitious compounds. No minimum order quantity is listed, and the product is commonly shipped in bulk vessel loads or bagged consignments under HS code 2621.
Typical Class F fly ash contains 55‑65 % SiO₂, 20‑30 % Al₂O₃, 5‑10 % Fe₂O₃, and a loss on ignition below 5 %, which aligns with industry standards for supplementary cementitious materials. The ash usually exhibits a fineness of at least 70 % passing a 45 µm sieve and a bulk density around 0.8‑1.0 g/cm³. Moisture content is typically kept under 5 % to ensure stable handling and storage.
The additive is used in concrete mixes, grout, masonry units and large‑scale infrastructure such as dams and piers, where improved durability and reduced permeability are required. Buyers should confirm the shipping incoterm, request the latest test report confirming ASTM C618 compliance, and agree on payment and insurance terms before loading. The product’s bulk nature makes it suitable for projects that demand high volumes of cementitious material.

Importers should first verify that the fly ash batch meets ASTM C618 by requesting the latest Certificate of Analysis and confirming the chemical composition, loss on ignition and pozzolanic activity index. It is also advisable to check that the supplier can provide the HS code 2621 documentation required for customs clearance in the destination country.
Typical logistics involve sea freight from a Canadian port, with lead times dependent on vessel schedules and any required pre‑shipment inspections. Buyers must agree on incoterms - usually FOB or CIF - and confirm payment terms such as L/C or T/T, ensuring that insurance coverage is arranged for the full transport period.
Quality control measures include arranging an independent third‑party inspection at the loading port, verifying moisture and fineness test results, and ensuring that all relevant certificates (e.g., ISO, test reports) are attached to the shipping documents. Maintaining this documentation will facilitate smooth customs clearance and guarantee that the material performs as expected in concrete applications.
