Calcium hypochlorite price

The most critical factor is the Available Chlorine content, typically ranging from 65% to 70%. Higher concentrations generally command a higher price but offer better efficiency for water treatment. You must also verify the moisture content (usually <3%) and particle size (granules vs. tablets), as these affect the dissolution rate and storage stability. Ensure the product is manufactured via the Sodium Process, which results in higher purity and better stability compared to the Calcium Process.

As a hazardous chemical, it must comply with UN 2880 (Hydrated) or UN 1748 (Dry) classification for Class 5.1 Oxidizing Substances. For water treatment applications, look for NSF/ANSI Standard 60 certification or EN 900 compliance. Suppliers must provide a valid Material Safety Data Sheet (MSDS) and a Certificate of Analysis (COA) for every batch to ensure the chemical composition meets safety and regulatory requirements.

For swimming pool disinfection, fast-dissolving granules or 20g/200g tablets are preferred for ease of dosing. In industrial wastewater treatment or aquaculture, bulk granules are more cost-effective. If the intent is drinking water purification, the product must have low insoluble matter (<5%) to prevent clogging of dosing pumps and ensure no harmful residues are left in the water supply.

Beyond the unit price, consider the packaging durability; Calcium Hypochlorite is corrosive, so UV-resistant plastic drums (typically 40kg or 45kg) are essential for long-distance shipping. Bulk purchasing (e.g., full container loads of 20-22 MT) can reduce costs by 10-15%. Additionally, factor in the shelf life, as chlorine loss occurs over time; sourcing from a factory with a high turnover rate ensures you receive fresh stock with maximum potency.

Calcium Hypochlorite is a Class 5.1 Oxidizer, meaning it can accelerate the combustion of other materials. The primary risk is improper stowage near heat sources or organic materials, which can lead to fire. Ensure the supplier uses IMDG-compliant packaging and that the shipping line is experienced in handling Dangerous Goods (DG). Always verify that the container is clean and dry before loading to prevent chemical reactions.

Request a tiered pricing structure based on raw material (lime and chlorine) market fluctuations. To secure quality, insist on a pre-shipment inspection by a third party like SGS or Intertek to verify the 'Available Chlorine' percentage. For long-term contracts, negotiate a quality guarantee clause that allows for claims if the chlorine degradation exceeds 2% within the first six months of storage.

Use secure payment methods such as Letters of Credit (L/C) for large volumes or Escrow services provided by reputable B2B platforms like Made-in-China.com. This ensures payment is only released upon verification of the Bill of Lading and DG certificates. Avoid suppliers who demand 100% upfront payment via untraceable methods, especially for new partnerships.

For shipments to the USA, ensure the supplier is EPA registered. For the EU, compliance with REACH regulations is mandatory. When shipping to tropical regions, prioritize double-lid drums to prevent moisture ingress. Always ensure the Dangerous Goods Declaration (DGD) is accurately completed to avoid customs seizures or heavy fines at the port of entry.
