Frequently Asked Questions
What is the difference between your calcium carbonate powder and calcite sand?
Calcium carbonate powder (GCC) covers 325–2500 mesh for filler and coating use. Calcite sand is a coarse granular product (10, 20 and 40–80 mesh) used as decorative aggregate for terrazzo, artificial stone, mortar and industrial flooring.
What CaCO₃ content and whiteness can you achieve?
CaCO₃ ranges from 88% to 98% for standard grades and 20%–97% for customised grades; whiteness ranges from 75 to 97. Batch test reports are issued for every shipment.
Do you supply food-grade or cosmetic-grade calcium carbonate?
Our 2500 mesh ultra-fine grade with CaCO₃ ≥ 96% and whiteness 93 is used as a cosmetic and food-grade auxiliary filler. Dust-proof professional packaging and OEM labelling are available.
How is the powder packed and shipped?
Standard packing is 25 kg or 50 kg woven bags, paper-plastic composite bags, kraft paper bags and 1000 kg / 1250 kg tonne bags. We load 25–27 tonnes per 20 ft container and ship from Dalian or Yingkou port.
