Sodium hypochlorite price

When sourcing Sodium Hypochlorite, the available chlorine content is the most critical metric. Standard industrial grades typically range from 10% to 15%. You must request a Certificate of Analysis (COA) for every batch to verify the stability index and free alkali content, which prevents rapid decomposition. Ensure the product meets ISO 9001 quality management standards and, if used for water treatment, check for NSF/ANSI 60 certification.

The price is primarily driven by the cost of raw materials (liquid chlorine and caustic soda) and electricity rates, as it is a chlor-alkali byproduct. Additionally, because it is a hazardous liquid with a short shelf life, logistics and specialized packaging (IBC tanks or Jerry cans) significantly impact the final landed cost. Seasonal demand for water treatment and swimming pool maintenance also causes price surges during spring and summer.

Sodium Hypochlorite is inherently unstable and decomposes over time, especially when exposed to heat, light, or heavy metal ions. Buyers should prioritize suppliers who offer freshly produced batches. Storage must be in cool, ventilated areas using UV-resistant HDPE containers. For long-distance cross-border shipping, ensure the supplier adds stabilizers to maintain the concentration level during the transit period.

As a corrosive substance (Class 8 Hazardous Material), it must have a comprehensive Material Safety Data Sheet (MSDS) updated to GHS standards. For export from China, the supplier must provide a Dangerous Goods Package Certificate and ensure the labeling complies with the IMDG Code for maritime transport. Always verify the supplier's Production License for Hazardous Chemicals.

Negotiate a 'Concentration at Destination' clause or request a higher initial concentration (e.g., shipping at 13% to ensure 12% arrival). Use reputable inspection agencies like SGS or Intertek to perform loading supervision and seal the containers to prevent tampering or dilution.

Focus on Total Landed Cost rather than just the EXW price. Ask for tiered pricing based on volume (e.g., 20ft FCL vs. LCL). Inquire about OEM/Private Labeling capabilities if you are a distributor. Always verify the supplier's Audit Report on Made-in-China.com to confirm they are a Gold Member or Audited Supplier with actual factory facilities.

Utilize Secured Trading Services provided by the platform to ensure funds are only released after the Bill of Lading (B/L) is uploaded and verified. For first-time orders, consider a Letter of Credit (L/C) or a 30% deposit with 70% balance against the copy of the B/L to minimize financial exposure.

Since it is a Class 8 Corrosive Liquid (UN1791), it cannot be shipped via standard air freight. You must use specialized chemical vessels or ISO tanks for bulk, or UN-approved drums for containerized sea freight. Ensure the shipping line accepts hazardous cargo and that the port of discharge has the infrastructure to handle corrosive chemicals.
