Quality Control

Our Magnesiumcarbonateheavy is manufactured under a stringent quality management system. We offer grades compliant with relevant pharmacopeial standards (USP/EP/BP) and food chemical codes (FCC). Every batch is accompanied by a comprehensive Certificate of Analysis (COA) detailing purity, heavy metal content, loss on drying, and other critical parameters to ensure it meets your specific application requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after initial use to prevent moisture absorption and caking.
