Import Calcium Carbonate — Buy in Bulk from Supplier in China

Shanghai Da Yu Biochemistry Co., Ltd. supplies calcium carbonate that is formulated specifically for pharmaceutical applications. The product conforms to USP 30, EP 2005, BP 2004 and CP 2005 standards, indicating strict control over calcium carbonate content and impurity levels. It is described as a fine white crystal with a low odour and a typical particle size that meets pharmaceutical grade requirements. The supplier notes that arsenic and lead concentrations are below 0.3 ppm, underscoring its suitability for health‑sensitive formulations.

In the pharmaceutical market, calcium carbonate usually achieves a purity of 99 % or higher, with impurity limits set below 10 ppm for heavy metals. Typical particle size for such grades ranges from 1 to 5 µm, providing optimal flow and compressibility for tablet manufacturing. Standard packaging for pharmaceutical calcium carbonate is 25 kg sealed bags, which protect the material from moisture and contamination. These typical parameters align with the supplier’s description and are widely accepted by drug manufacturers.

Manufacturers of tablets, capsules and dietary supplements source this grade to act as a filler, binder or calcium source. Trade terms often involve FOB or CIF from Shanghai ports, with buyers needing to confirm minimum order quantities directly with the company. Payment is commonly made via L/C or T/T, and the supplier advises requesting the latest pharmacopeial certificates before finalising the purchase.
