Ralph Rapat International Co., Ltd. offers natural gypsum lumps that contain calcium sulfate dihydrate (CaSO4·2H2O) with a purity range of 88‑92 % and are sourced from Thailand. The lumps are supplied in sizes from 0 to 250 mm, providing a versatile raw material for various processing needs. The supplier does not disclose a specific annual capacity, but positions the product for large‑scale industrial use.
The dihydrate form is commonly used in cement production as a set retarder, in agricultural soil amendment programmes and for drywall manufacturing after grinding. In the industry the material is typically crushed to 0‑5 mm particles for use in blends, and it exhibits a bulk density of about 2.2 t/m³ with a moisture content around 2‑3 %, which is standard for natural gypsum lumps. No specific certifications are listed, so buyers should request test reports to confirm compliance with their quality standards.
Primary customers include cement factories, construction material manufacturers and agribusinesses that require gypsum as a functional additive. The product is shipped in bulk, allowing buyers to arrange FOB terms from a Thai port and to specify container or bulk vessel loading. Interested parties should confirm the minimum order quantity, preferred Incoterm and expected lead time directly with the supplier.

Prior to ordering, importers should ask for a recent mill test report that confirms the 88‑92 % purity and the moisture range of 2‑3 %. Verifying that the material originates from the declared Thai source and checking the supplier’s harbour‑tier verification status will also help mitigate risk.
Shipping is generally arranged as bulk sea freight from a Thai port, with the buyer able to specify FOB or CIF terms. It is important to confirm the expected lead time, the minimum order quantity and the preferred payment method, as these details are not disclosed in the public listing.
Upon receipt, a third‑party inspection should be conducted to validate bulk density, particle size distribution and moisture content against the supplied specifications. Relevant documents such as the mill test report, packing list and bill of lading must be reviewed to ensure the shipment complies with the agreed terms and to smooth customs clearance.
