About SANXIN New Materials

We are a leading calcium carbonate manufacturer based in Hechi, Guangxi, China, with over 20 years of experience in powder production. As an integrated enterprise combining ore mining, R&D, processing, and international trade, we operate two high-quality calcite mines and maintain strict quality control across the entire supply chain.

Our mission is to deliver premium-grade calcium carbonate powders that enhance product performance and reduce manufacturing costs for our global partners. All our products are derived from natural large calcite — a superior raw material compared to marble or limestone due to its higher calcium content, whiteness, and lower oil absorption.

ISO & FCC Compliant
