Sodium percarbonate

Buyers should prioritize Active Oxygen content, which typically ranges from 13% to 14.5% for high-quality grades. It is crucial to distinguish between Coated and Uncoated types; coated sodium percarbonate offers superior moisture resistance and stability when blended with other detergents. Additionally, verify the bulk density (typically 0.80–1.20 g/cm³) and particle size distribution to ensure compatibility with your specific formulation or application.

Sodium Percarbonate is a versatile eco-friendly oxidizing agent. Its primary applications include heavy-duty laundry detergents and 'oxygen bleach' powders. In aquaculture, it serves as a rapid oxygen release agent to increase dissolved oxygen levels. It is also widely used in industrial water treatment, pulp bleaching, and as a disinfectant in food processing environments due to its decomposition into only water, oxygen, and soda ash.

As a hazardous chemical (Class 5.1 Oxidizer), it must have a valid Material Safety Data Sheet (MSDS/SDS). Ensure the supplier complies with REACH regulations for the EU market or TSCA for the US. For quality management, look for ISO 9001:2015 certification. If used in water treatment or food-contact surfaces, check for NSF certification or local food-grade compliance equivalents.

Request stability test reports from the supplier, specifically measuring the Active Oxygen loss rate over time under accelerated aging conditions. High-quality coated variants should maintain over 90% activity after one year if stored correctly. Ensure the packaging uses vented liners or specialized moisture-proof bags to prevent pressure buildup and decomposition during storage.

Sodium Percarbonate is classified under UN Number 3378 (Oxidizing Solid). It requires UN-certified packaging (usually double-layer woven bags or fiber drums). During sea freight, it must be stored away from heat sources and flammable materials (Stowage Category A). Ensure your freight forwarder is experienced in Dangerous Goods (DG) handling to avoid port rejections or heavy fines.

Utilize secure payment and inspection services provided by reputable platforms like Made-in-China.com. Always conduct a pre-shipment inspection (PSI) through third parties like SGS or Intertek to verify the Active Oxygen levels and packaging integrity before the balance payment is released. This prevents the risk of receiving sub-standard or degraded chemical batches.

Price is heavily influenced by the cost of raw materials (Soda Ash and Hydrogen Peroxide). Negotiate based on volume tiers; orders exceeding 20 metric tons (full container load) usually command significantly lower unit prices. Consider long-term supply contracts to hedge against price volatility in the chemical market, and always ask for FOB vs. CIF quotes to compare logistics cost-efficiency.

Be aware of Anti-Dumping Duties (ADD) that certain regions (like the EU or USA) may impose on chemical imports from specific countries. Check the Harmonized System (HS) Code (typically 2836.99) against your local customs tariff schedule to calculate the Total Landed Cost accurately, including any environmental taxes or specialized chemical import permits required by your government.
