Import Best Selling Ground Calcium Carbonate Powder — Buy in wholesale FOB from Supplier in Viet Nam

Ground Calcium Carbonate Powder from Kego Company Limited is a finely milled mineral product derived from natural limestone quarried in Viet Nam. The material exceeds 98% purity, with particle sizes available in multiple mesh cuts to suit plastics compounding, paint formulation, and rubber reinforcement. The powder exhibits a consistent whiteness and low silica content, making it compatible with food-grade and pharmaceutical-grade applications where stringent safety thresholds apply. Kego Company Limited operates from Ha Noi with a harbor trust tier, though buyers should note the current response rate and average response hours require direct confirmation for urgent enquiries.

The typical production process involves dry grinding of calcitic limestone followed by air classification to achieve narrow particle distribution. Standard grades for industrial use generally fall within D50 ranges of 1-25 microns, with top-cut specifications controlling coarse fractions above 45 microns. Surface treatment with stearic acid or other coupling agents is common for polymer applications to improve dispersion and reduce moisture sensitivity. The material's Mohs hardness of 3.0 and specific gravity near 2.7 g/cm³ make it a functional filler that reduces formulation costs while maintaining mechanical properties in PVC, PP, and epoxy systems. Natural calcium carbonate content typically ranges from 96-99% CaCO₃, with magnesium carbonate and iron oxide as principal accessory minerals.

Primary buyers include masterbatch manufacturers, paint and coating producers, paper mills seeking coating pigments, and construction material suppliers using GCC as a concrete additive or joint compound filler. The product ships in standard 25 kg paper bags, 500-1000 kg bulk bags, or silo trucks depending on volume. Kego Company Limited offers FOB and CIF incoterms from Vietnamese ports, though exact MOQ, lead times, and packaging configurations must be confirmed directly with the supplier. Buyers should request current SGS or ISO certificate validity and specify whether food-grade compliance (meeting E170 additive standards) is required for their application.

Kego Company Limited is headquartered at 78 Duy Tan Street, Cau Giay District, Ha Noi, Viet Nam, with postal code 10000. The company holds a harbor trust tier within the marketplace verification system. The supplier's listed response rate shows 0.00% with zero average response hours recorded, which indicates that direct contact channels (email, phone, or the supplier's own website) may be necessary for reliable communication. No employee count, annual revenue, year of establishment, or specific factory location details are provided in the available profile data.

The listing presents Kego Company Limited as offering ground calcium carbonate powder for export, with stated capabilities across multiple industrial sectors. The supplier claims ISO and SGS certification, though buyers should independently verify the scope, issuing body, and current validity of these certificates. The address in Ha Noi suggests administrative or trading operations; manufacturing or processing facilities may be located elsewhere in Viet Nam, possibly near limestone deposits in provinces such as Ha Nam or Ninh Binh. Buyers should clarify whether Kego operates its own quarries and grinding mills, or functions as a trading company coordinating production from third-party mills.
