Import Calclium Carbonate Granules — Buy in Bulk from Supplier in China

Calcium carbonate granules from Shanghai Da Yu Biochemistry Co., Ltd. are a clean, odorless and fine-grained material supplied in bulk for industrial use. The product is presented as a uniform granule, suitable for applications where consistent particle size and high purity are critical. The granules are non-toxic and designed for safe handling in controlled industrial environments.

The material is typically composed of at least 98 percent calcium carbonate, with trace elements varying by extraction and processing methods. Standard industry grades for such granules include food grade, pharmaceutical grade and industrial grade, each meeting distinct purity and particle distribution requirements. Granule size often ranges from 0.5 mm to 3 mm in diameter for industrial applications, with tighter tolerances available for specialized uses. Flow properties are enhanced by the granular form, reducing dust and improving ease of handling in automated systems.

These granules are primarily used as a filler or additive in the manufacturing of plastics, rubber, paints and adhesives, where they contribute to improved mechanical properties and cost efficiency. Buyers in the pharmaceutical and food sectors utilize them as a calcium supplement or processing aid, provided the grade meets regulatory standards. The product is typically shipped in 25 kg or 50 kg multi-layer paper bags with polyethylene liners, and bulk shipments are palletized for export. Confirm packaging options and certifications such as FDA or FSSAI with the supplier before ordering.
