Safe and Healthy for Food Applications
We offer Calcium carbonate powder edible, reflecting our commitment to safety and health. We use high-purity natural limestone as the raw material, which undergoes strict processing including sorting, crushing, screening, and washing.
Our factory is certified under ISO 9001, ISO 14001, and ISO 45001, and operates a complete quality management system. We do not just supply raw materials; we help safeguard food safety. Our edible-grade calcium carbonate powder is designed with end-user safety in mind.
Key Specifications and Strict Safety Control
We strictly control heavy metals and harmful impurities to ensure compliance with food safety requirements. The table below outlines our quality standards.
We use only high-purity natural limestone ore to ensure safety from the source. Testing is carried out in accordance with relevant food-grade standards to ensure compliance of calcium carbonate content. We also strictly control magnesium content, a key quality indicator for edible-grade materials.
Our Calcium carbonate powder edible is safe and reliable for its intended applications.

Versatile Grades for Food and Feed Applications
Calcium carbonate powder edible is widely used in food additives, feed additives, and nutritional products.
The 8–16 mesh grade is commonly used in feed mills as a calcium source for poultry. The 30–50 mesh grade is used in food manufacturing for calcium-fortified products. The 50–80 mesh grade is suitable as an excipient or filler in tablets and capsules.
We support custom gradation and can adjust particle size and packaging according to your requirements. Every batch undergoes heavy metal testing to ensure product safety and compliance. Standard orders are shipped within 3–5 working days after deposit confirmation.
