Calcium Oxide
Calcium oxide supplied by Guilin Hongxing Chemical Co., Ltd. is food grade quicklime with a minimum CaO content of 99%. The product is a white or grey particle or powder, conforming to Chinese standard GB30614, and is approved for use as a processing agent in food production with no residual limits. It is produced to meet international food safety requirements, with controlled impurities such as arsenic (≤0.4 mg/kg), fluoride (≤76 mg/kg), and lead (≤0.08 mg/kg).
The material is supplied with a particle size distribution where 90% passes through 325 mesh, ensuring fine and consistent reactivity. Magnesium and alkali salt content is capped at 1.1% by weight, and acid-insoluble substances do not exceed 0.2%. Loss on ignition is limited to 3.0%, indicating low volatile content and high stability. This grade is typical for applications requiring precise chemical control, such as pH adjustment in water treatment or as a processing aid in food manufacturing.
Industrial buyers use this calcium oxide in bulk quantities for water treatment, chemical manufacturing, and food processing. The product’s high purity and fine particle size make it suitable for applications where consistency and low impurity levels are critical. Buyers should confirm packaging options, as quicklime is typically shipped in moisture-resistant bags or bulk containers to prevent hydration. Trade terms such as MOQ, incoterms, and lead times are available upon direct inquiry with the supplier.

Sourcing Calcium Oxide from Guilin Hongxing Chemical Co., Ltd. - China Import Guide
Before placing an order, verify the product’s compliance with your local regulations for food-grade or industrial use. Confirm that the calcium oxide meets the required purity and impurity limits for your specific application, particularly if it involves direct or indirect contact with food products. Request a certificate of analysis (COA) for the batch you intend to purchase to ensure it aligns with the stated specifications.
Discuss logistics details such as packaging, loading methods, and transport conditions to prevent hydration or contamination. Quicklime reacts with moisture, so ensure the supplier uses sealed, moisture-proof containers. Clarify incoterms (e.g., FOB, CIF) and lead times, as these can vary based on the supplier’s production schedule and shipping arrangements from Guilin, China.
Quality checks should include testing for CaO purity, particle size distribution, and impurity levels such as arsenic, fluoride, and lead. For food-grade applications, confirm that the product meets GB30614 or equivalent standards. Request documentation such as material safety data sheets (MSDS) and COAs, and consider third-party inspection for large shipments to verify compliance with your requirements.
