Calcium hypochlorite ca clo 2

Buyers must prioritize the Available Chlorine content, typically ranging from 65% to 70% for high-quality industrial and pool grades. Ensure the product is produced via the Sodium Process (rather than the Calcium Process) for higher stability, lower impurity levels, and better solubility. Additionally, verify the moisture content is below 5-10% to prevent spontaneous decomposition during storage.

For water treatment, ensure the supplier meets NSF/ANSI Standard 60 certifications. For general quality management, ISO 9001 is essential. Since Calcium Hypochlorite is a Class 5.1 Oxidizer (UN 2880), the manufacturer must provide a valid Material Safety Data Sheet (MSDS) and a Certificate of Analysis (COA) for every batch to ensure compliance with international safety regulations.

Selection depends on the application: Granular form is preferred for industrial water treatment and aquaculture due to rapid dissolution. Tablet form (20g or 200g) is ideal for swimming pool disinfection to ensure slow-release chlorination. For bleaching in textile or paper industries, high-purity powder is required to avoid fabric staining from insoluble residues.

Calcium Hypochlorite is inherently unstable; therefore, you should request stability test reports. High-quality products should have an annual chlorine loss of less than 1% when stored correctly. Ensure the packaging uses UV-resistant, high-density polyethylene (HDPE) drums with secure locking rings to prevent moisture ingress and gas buildup.

As a Class 5.1 Dangerous Good, it must be shipped in UN-approved packaging (usually 40kg or 45kg plastic drums). You must ensure the shipping line accepts DG (Dangerous Goods) cargo and that the IMDG (International Maritime Dangerous Goods) Code is strictly followed. Always confirm the port of discharge has the capability to handle and store Class 5.1 oxidizers.

Utilize Made-in-China.com's secured payment services to protect your funds until shipping documents are verified. It is highly recommended to hire a third-party inspector (like SGS or Intertek) to perform a Pre-Shipment Inspection (PSI) to verify the chlorine content and packaging integrity before the balance payment is made.

Prices are heavily influenced by the cost of raw materials (chlorine and caustic soda) and energy prices. Negotiate based on volume tiers; for example, ordering a full 20ft container (approx. 18-21 MT) can significantly reduce the per-unit freight and product cost. Ask for formula-based pricing if you intend to establish a long-term annual supply contract.

The product must be stored in a cool, dry, and well-ventilated area away from heat sources. It is critical to keep it isolated from organic materials, acids, and fuels, as contact can cause violent combustion or explosions. Ensure your warehouse staff are trained in hazardous material handling and have the correct PPE.
