Sodium chlorite price

When sourcing Sodium Chlorite, the price is primarily driven by purity levels and physical form. The most common industrial grades are 80% powder/solid and 25%-31% liquid solution. You must verify the CAS No. 7758-19-2 to ensure product authenticity. For water treatment or food processing, ensure the product meets low-chlorate and low-heavy metal specifications to avoid downstream contamination.

Sodium Chlorite is a highly regulated chemical. Buyers should prioritize suppliers who provide ISO 9001:2015 for quality management and ISO 14001 for environmental standards. For international trade, a valid MSDS (Material Safety Data Sheet) and COA (Certificate of Analysis) for every batch are non-negotiable. If used for drinking water, look for NSF/ANSI 60 certification to ensure safety compliance.

The price is highly sensitive to the cost of raw materials like Sodium Chlorate (NaClO3) and Hydrogen Peroxide, as well as energy costs during the electrolytic process. To optimize costs, B2B buyers should consider bulk purchasing (FCL - Full Container Load) to reduce the high per-unit cost of hazardous material logistics. Prices typically fluctuate based on environmental inspection cycles in manufacturing hubs like China.

Requirements vary significantly by application: In textile and paper bleaching, high-concentration powder is preferred for efficiency. In water treatment and disinfection, liquid solutions are often favored for ease of dosing. For ClO2 generation, the precursor's stability and pH levels are critical to ensure a high conversion rate and operational safety.

Sodium Chlorite is classified as a Class 5.1 Oxidizing Agent (UN 1496 for solid, UN 1908 for solution). It requires specialized hazardous goods packaging (UN-certified drums or IBC tanks). You must work with freight forwarders experienced in DG (Dangerous Goods) handling and ensure the shipping line accepts Class 5.1 chemicals to avoid port rejection or heavy fines.

To ensure transaction security, use Made-in-China.com's secured payment services or Letters of Credit (L/C) for large volumes. Always request a pre-shipment inspection (PSI) by third parties like SGS or Intertek to verify the chemical composition and packaging integrity before the final balance is paid.

Negotiate based on annual volume commitments rather than one-off spot buys to secure 'VIP' pricing. Ask for tiered pricing based on raw material index links. Additionally, clarify Incoterms early; while FOB is standard, CIF or CFR might be more complex for hazardous goods, so ensure the supplier has a proven track record of successful international DG shipments.

The biggest risks include moisture absorption (for powder) leading to caking, and leakage (for liquid) causing fire hazards. Ensure the contract specifies palletization and shrink-wrapping for stability. Also, be aware of anti-dumping duties that some countries may impose on Chinese chemicals; always check your local customs tariff code (HS Code 2828.90) before importing.
