Sodium hypochlorite 10% price manufacturers

When sourcing 10% Sodium Hypochlorite, you must verify the Available Chlorine content (which should be strictly monitored as it degrades over time). Ensure the Alkali content (as NaOH) is within the range of 0.5% to 1.0% to maintain stability. Additionally, check for heavy metal impurities (like Iron or Copper) which can catalyze decomposition, and confirm the density aligns with the 1.15-1.20 g/cm³ range typical for this concentration.

Sodium Hypochlorite is inherently unstable and decomposes due to UV light, heat, and time. For B2B buyers, this means you should prioritize suppliers with high inventory turnover and those who provide freshly manufactured batches. Request a Certificate of Analysis (COA) for every batch and consider the ambient temperature during transit, as temperatures above 30°C significantly accelerate the loss of active chlorine.

Suppliers must provide a Material Safety Data Sheet (MSDS) compliant with GHS standards. For water treatment applications, look for NSF/ANSI 60 certification. If the product is intended for the European market, REACH registration is mandatory. For the US market, ensure the manufacturer is EPA registered if the product is marketed as a disinfectant or pesticide.

Due to its corrosive nature and potential for gas evolution, 10% Sodium Hypochlorite must be stored in UV-resistant, high-density polyethylene (HDPE) containers. For bulk shipments, ensure the use of vented caps to prevent pressure buildup. Verify that all packaging meets UN-rated standards for Class 8 Corrosive Substances to ensure safety during sea or land transport.

Sodium Hypochlorite is classified as a Class 8 Corrosive Material (UN 1791). The primary risk is leakage and gas emission, which can lead to container damage or regulatory fines. You must work with freight forwarders experienced in Dangerous Goods (DG) and ensure the vessel space is booked specifically for DG cargo. Avoid long transit times or transshipments in tropical regions to prevent significant concentration loss.

To mitigate risk, use Secure Payment services provided by reputable platforms like Made-in-China.com, which offer escrow-like protection. For quality assurance, hire a third-party inspection agency (such as SGS or Intertek) to perform a 'Loading Supervision' and 'Pre-shipment Inspection' to test the active chlorine levels right before the container is sealed.

Negotiate based on Total Cost of Delivered Active Chlorine rather than just the price per ton of liquid. Ask for volume-based tiered pricing and inquire about packaging return programs or discounts if you provide your own IBC tanks. Ensure the contract includes a quality claim clause that specifies the minimum acceptable chlorine percentage upon arrival at the destination port.

Check the HS Code (typically 2828.90) for specific import duties in your country. Many regions require an Import License for Precursor Chemicals or specific environmental permits. Ensure the supplier provides a Commercial Invoice, Packing List, and Bill of Lading that perfectly match the chemical description on the Dangerous Goods Declaration to avoid customs seizures.
