Navigating the diverse landscape of calcium carbonate grades can be challenging for manufacturers. At NINGBO INNO PHARMCHEM CO.,LTD., we aim to simplify this process by providing clear guidance on selecting the appropriate grade for your specific needs, whether it's for pharmaceutical or food applications. Understanding the differences between USP (United States Pharmacopeia) Grade and Food Grade calcium carbonate is crucial for ensuring product quality and compliance.

USP Grade Calcium Carbonate, like our Pharmaceutical Grade Calcium Carbonate Powder, meets the stringent purity and testing requirements set forth by the United States Pharmacopeia. This grade is essential for pharmaceutical applications, including use as an active pharmaceutical ingredient (API) in antacids and calcium supplements, or as an excipient in tablets and capsules. The rigorous testing ensures minimal impurities, consistent physical properties, and reliable performance in drug formulations. When you buy pharmaceutical calcium carbonate from us, you are assured of a product that meets these high standards, supporting the safety and efficacy of your medicinal products.

Food Grade Calcium Carbonate, while also requiring high purity, adheres to standards set by regulatory bodies like the FDA for consumption. It is commonly used as a calcium supplement in food products, as a processing aid, or as a colorant and filler. While both grades are pure, USP Grade often undergoes more extensive testing for specific pharmaceutical impurities and may have tighter specifications on parameters like particle size distribution or heavy metal content, crucial for drug manufacturing. NINGBO INNO PHARMCHEM CO.,LTD. offers both high-quality calcium carbonate powder suitable for food applications as a calcium carbonate food additive, as well as our premium USP/Pharmaceutical grade.

The decision between USP and Food Grade often depends on the intended end-use. For products regulated as drugs or dietary supplements with pharmaceutical claims, USP Grade is typically required. For general food fortification or processing, Food Grade is appropriate. NINGBO INNO PHARMCHEM CO.,LTD. is equipped to supply both, ensuring our clients have access to the precise calcium carbonate they need for their health care products and food items. Our expertise in calcium carbonate sourcing and manufacturing makes us a reliable partner for all your ingredient requirements.
