Frequently Asked Questions

What is the difference between nano and precipitated calcium carbonate?

Nano calcium carbonate has particle sizes below 100 nm, offering enhanced mechanical properties. Precipitated calcium carbonate (PCC) is chemically synthesized with high purity and controlled particle size, typically larger than nano-grade.

Can you provide OEM/ODM services?

Yes, we specialize in OEM/ODM calcium carbonate projects with custom formulations, packaging, and labeling.

Are your products suitable for food and pharmaceutical use?

Yes, our pharmaceutical-grade calcium carbonate meets USP, BP, and food safety standards (E170).

What is the minimum order quantity (MOQ)?

MOQ varies by product type and packaging. Please contact us for specific details based on your requirements.
