Quality Control

Our Calcium Magnesium Dicarbonate is produced under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, mineral content, and heavy metal limits. Certificates of Analysis (COA) are provided with every shipment, confirming compliance with relevant standards such as FCC for food-grade material or in-house specifications for technical grades.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, store in a cool, dry place at a controlled room temperature (15-25°C). Ensure the storage area is well-ventilated and away from incompatible materials. Keep containers sealed when not in use to prevent moisture absorption and caking.
