从China供应商批发进口74% Min Calcium Chloride Powder — FOB条款

Weifang Qihui Chemical Co., Ltd. supplies calcium chloride powder with a declared minimum purity of 74% as CaCl2, originating from Binhai Economical Development Zone in Weifang, Shandong Province. The powder form is offered in 25kg bags or jumbo bags for bulk trade, with the supplier noting applications across food processing, water treatment, de-icing, and dust control. The hygroscopic nature of this calcium chloride grade makes it suitable for moisture absorption tasks where rapid dissolution is required.

The 74% minimum purity corresponds to the dihydrate form (CaCl2·2H2O), which is the standard industrial grade for most non-food applications and many food-grade uses with appropriate certification. Typical calcium chloride powder at this purity level contains approximately 74-77% CaCl2 by weight when measured as the dihydrate, with the balance being moisture and trace impurities. Standard industrial-grade material may contain up to 1% alkali metal chloride, 0.5% magnesium, and 0.3% insoluble matter depending on production method (solvay process or natural brine refinement). The powder particle size distribution is typically specified as 90% passing 20 mesh (850 microns) for applications requiring rapid dissolution, though this should be confirmed with the supplier for this specific lot.

Primary buyers include chemical distributors, road maintenance contractors, water treatment facilities, and food processors requiring firming agents. The product serves as a desiccant in humidity control systems, a dust suppressant on unpaved roads, and a de-icing agent with effective temperature depression to approximately -30°C for 29% solutions. Importers should verify the certificate of analysis for each shipment, confirm whether food-grade or industrial-grade certification applies to their intended use, and clarify packaging specifications and Incoterms directly with Weifang Qihui Chemical Co., Ltd., as the current listing does not specify FOB, CIF, or other trade terms.

Weifang Qihui Chemical Co., Ltd. operates from Binhai Economical Development Zone in Weifang, Shandong Province, China, a region with established chemical manufacturing infrastructure and access to brine resources from coastal salt deposits. The supplier carries an imported tier classification with harbor trust tier, and shows a response rate of 0.00 with zero average response hours recorded, which prospective buyers should note when planning procurement timelines. The listing does not disclose production capacity, number of employees, year of establishment, revenue figures, or specific client references, so these cannot be verified from available information.

The supplier's offering focuses on calcium chloride powder for industrial and food-grade applications, with emphasis on moisture absorption, de-icing, and dust control end uses. No ISO, FDA, or other certification numbers are provided in the source data, despite generic references to such standards in the original description, buyers should request copies of current certificates directly. The company profile lacks detail on whether it is a manufacturer, trader, or hybrid operation, and the extent of vertical integration (brine extraction through to finished product) is unstated. Importers are advised to conduct due diligence on production capabilities, quality control procedures, and export experience before committing to volume orders.
