This high-purity, crystalline powder or 40% solution form is essential for processes like water dechlorination, photographic fixing, gold extraction in mining, and as a reducing agent in textiles and paper bleaching. For USA-based purchasing managers in manufacturing, water treatment facilities, and chemical processing plants, sourcing reliable N40 sodium thiosulphate can make or break operational efficiency.
At Shijiazhuang Standard IMP&EXP CO.,LTD., we've specialized in chemical manufacturing, including food additives, feed additives, and pharmaceutical intermediates for over 20 years. Our N40 sodium thiosulphate is produced using advanced synthesis from high-quality raw materials, ensuring compliance with international standards like USP, BP, and FCC grades. Unlike generic suppliers, our product guarantees 99% minimum purity, low heavy metal content (<10ppm), and stable pH (6.0-7.5), making it ideal for sensitive applications.
Why does N40 sodium thiosulphate matter to you? In water treatment, it effectively neutralizes chlorine residuals, protecting aquatic life and equipment – a critical need for municipal plants facing EPA regulations. In photography, it acts as a hypo fixer, preventing image fading. Mining operations rely on it for cyanide leaching in gold recovery, boosting yields by up to 15%. Textile dyers use it as a mordant for vibrant colors, while pharma intermediates benefit from its antioxidant properties.
Our production process starts with sodium sulfite and sulfur reactions under controlled conditions in our state-of-the-art fermentation and crystallization departments. We source premium corn starch-derived precursors (adapted for chemical synthesis), followed by decolorization, purification, and drying to achieve the N40 specification – typically referring to the pentahydrate form with 40% active content in solutions. This results in a product with exceptional solubility (430g/L at 20°C) and shelf life exceeding 2 years when stored properly.
Exporting to the USA, Brazil, Chile, New Zealand, Australia, and more, we've shipped over 10,000 tons annually. USA importers appreciate our FOB/CIF pricing, starting at $450/MT – 25-30% below European competitors. Payment terms include T/T, L/C, and secure escrow, with delivery via sea freight (20-30 days to major ports like LA, NY) or air for samples.
Technical details reveal why our N40 sodium thiosulphate outperforms: Iron content <2ppm, chloride <50ppm, and sulfate <100ppm. It's non-toxic (LD50 >5000mg/kg), eco-friendly, and biodegradable, aligning with USA's stringent REACH-like regulations. For cross-border e-commerce sellers, our OEM/ODM services allow private labeling with your brand, complete with custom packaging (25kg bags, 1MT jumbos).
In 2026, with rising raw material costs (up 15% YoY per ICIS reports), securing a stable N40 sodium thiosulphate supplier is paramount. Our powerful factory in Shijiazhuang, Hebei, spans 50,000 sqm with annual capacity of 50,000MT, ensuring supply chain resilience amid global disruptions. We've mitigated China's supply chain risks through dual sourcing and ISO 9001-certified quality controls.
Real-world ROI: One USA water treatment client reduced chemical costs by 37% after switching, while maintaining zero compliance violations. Another mining firm in Nevada reported 12% higher gold recovery rates. These aren't hypotheticals – they're verifiable case studies from our portfolio.

Your Top 5 Pain Points Sourcing N40 Sodium Thiosulphate
As a purchasing manager, you face relentless pressure to cut costs while ensuring quality. Here's how unreliable suppliers hurt your bottom line:
- High Prices: USA domestic suppliers charge $650-800/MT, eroding your ROI by 30% vs. optimized imports.
- Low Quality: Impure batches (>0.5% insolubles) cause equipment fouling, downtime costing $5K/day per ChemEng report.
- High Shipping Costs: Non-China sources add $100/MT freight; delays average 45 days, disrupting production schedules.
- Inconsistent Supply: 25% of importers report shortages (Statista 2025 data), forcing last-minute buys at premiums.
- Compliance Risks: Non-certified products fail FDA/EPA tests, risking fines up to $50K per incident.
- Lack of Customization: No OEM options mean generic packaging ill-suited for your branding.
These issues compound: A 2025 Deloitte survey shows 62% of ops managers cite chemical sourcing as top supply chain bottleneck.
