Dustless Chalk Powder from Khushi Minerals is a processed form of calcium sulfate dihydrate (CaSO4·2H2O), derived from natural gypsum and refined to eliminate airborne particulates. The product contains 29.4% calcium and 23.5% sulfur by weight, with a purity profile suitable for educational and industrial chalk manufacturing. It is supplied in standard bulk packaging of 20kg, 25kg, 30kg, 38kg, and 40kg multi-layer kraft bags, designed to resist moisture during storage and transit.
This material is not raw gypsum but a mechanically milled and dried grade optimized for low dust emission. Typical industry standards for dustless chalk powder require moisture content below 1.5% and particle size distribution where 95% passes through a 150-micron sieve. The absence of silica or clay fillers distinguishes it from lower-grade alternatives, making it compliant with indoor air quality guidelines in schools and studios.
Buyers include chalk manufacturers in Southeast Asia, the Middle East, and Eastern Europe who require consistent bulk feedstock for extrusion or molding processes. The minimum order quantity is 5 metric tonnes per shipment, with delivery via ocean cargo, rail, or road from Porbandar port. Trade terms are typically FOB Porbandar or CIF destination, with payment via LC or TT. Lead times average 10 - 14 days after order confirmation.

Before placing an order, verify the chemical composition via a recent certificate of analysis (CoA) showing calcium sulfate dihydrate content, moisture levels, and absence of fillers. Confirm the packaging integrity - multi-layer kraft bags with polyethylene lining are essential to prevent moisture ingress during transit from Porbandar. Request batch-specific test results for particle size distribution and dust emission, not generic claims.
Logistics are handled via sea freight from Porbandar port, with road transport to the port for consolidation. Lead time is typically 10 - 14 days after payment, but customs clearance in destination countries may add 5 - 10 days. Incoterms are usually FOB Porbandar; CIF terms require confirmation of insurance coverage for bulk cargo. Payment is commonly via irrevocable LC or TT, with 30% advance and 70% against BL copy.
On arrival, inspect the outer packaging for tears or moisture stains. Open a random sample of bags and check for clumping, discoloration, or odor. Use a moisture meter to confirm levels are under 1.5%. Retain a 1kg sample per batch for lab testing if quality disputes arise. Request a mill test report and export health certificate from the supplier to meet import regulations in your country.
