+44 7789 787494As a leading supplier to China, we export high-grade Calcium Carbonate structured directly for your industrial requirements. China is the world's largest consumer of metallurgical ores. We supply premium Muslim Bagh chromite directly to major Chinese smelters, offering a highly sought-after Cr:Fe ratio of 2.5:1+ ideal for blending in high-carbon ferrochrome (HCFeCr) production.Indus Ores, Minerals & Resources exports high-purity Calcium Carbonate (CaCO3) sourced from the crystalline calcite and white marble belts of Khyber Pakhtunkhwa (Swabi, Buner, Nowshera, and Mohmand) and the high-calcium limestone formations of Punjab and Sindh (Attock, Margalla, and Thatta). Utilizing precision ball-mill and air-classification circuits, we supply both uncoated Ground Calcium Carbonate (GCC) and stearic acid surface-coated grades alongside raw crystalline calcite lumps—delivering exceptional ISO whiteness (95%–98%), ultra-low iron oxide (<0.03%), and controlled top-cut micron sizing (D97 from 5μm to 45μm) for international PVC pipe, masterbatch, paint, paper, rubber, and construction chemical manufacturers.
How to import Calcium Carbonate from Pakistan to China? Indus Minerals exports high-grade Calcium Carbonate to China via Karachi Port. The standard minimum order quantity is 1,000 MT (Scalable up to 5,000 MT/month) with a typical lead time of 30-45 days to main ports to major ports such as Tianjin, Lianyungang, Qingdao, Qinzhou. Payment terms are 100% Irrevocable L/C at sight from top-tier bank. All shipments meet CIQ (China Inspection and Quarantine) Compliance, CCIC Pre-shipment Inspection.
