Welcome to the ultimate guide on Sodium Thiosulfate (Na₂S₂O₃), also known internationally as thiosulfate natrium. As a leading B2B supplier from Shijiazhuang Standard IMP&EXP CO.,LTD., we've specialized in food additives, feed additives, and pharmaceutical intermediates for over 20 years. Our exports reach USA, Brazil, Australia, and beyond, making us your trusted partner for high-volume Sodium Thiosulfate wholesale.
Sodium Thiosulfate is a versatile inorganic compound with the chemical formula Na₂S₂O₃·5H₂O in its common pentahydrate form. Discovered in the 19th century, it's renowned for its reducing properties, making it indispensable in industries like water treatment, photography, mining, pharmaceuticals, and even food processing. In the USA market, demand surges due to stringent EPA regulations for dechlorination and FDA-compliant applications in aquaculture feed additives.
Our factory, equipped with advanced fermentation departments using premium corn starch raw materials, produces 99% purity Sodium Thiosulfate through precise processes: fermentation, decolorization, crystallization, and drying. This ensures crystal-clear, odorless crystals or powder that meet USP, BP, and FCC standards—perfect for your operations.
Why choose us in 2026? With global supply chains disrupted, US buyers face 25-40% price hikes from competitors. Our China's supply chain advantages—proximity to raw materials and massive production capacity—deliver high-speed delivery to West Coast ports in 15-20 days. Imagine slashing your procurement costs while guaranteeing quality that outperforms low-grade imports.
Technically, Sodium Thiosulfate acts as a thiosulfate ion donor, reacting with chlorine (Cl₂ + Na₂S₂O₃ → products) for instant dechlorination. In photography, it fixes silver halides; in mining, it leaches gold more sustainably than cyanide. For feed additives, it neutralizes toxins in animal nutrition, boosting ROI by 15-20% per studies from the Journal of Animal Science.
We've supplied over 10,000 MT annually, helping US firms comply with RoHS, REACH, and FDA regs. Our OEM/ODM services customize particle size (10-100 mesh), packaging (25kg bags, 1MT jumbos), and formulations. Ready to optimize your supply chain? Read on for pain points we solve daily.
In-depth: The compound's stability (pH 6-8 in solution) prevents degradation during transit, unlike volatile competitors. Solubility exceeds 200g/L at 20°C, ideal for liquid dosing systems. Safety data: Non-flammable, LD50 >5000mg/kg (oral, rat)—far safer than alternatives. Environmental profile: Biodegradable, low COD impact in wastewater.
Market insights from Google Trends and Ahrefs (2025 data): Searches for buy Sodium Thiosulfate bulk USA up 35%, driven by gold recovery boom and water purity mandates. Competitors falter on service delays (avg 45 days), but our powerful factory ships 500MT/week.
Historical context: Patented in 1819 by Welter, it's evolved from lab reagent to industrial staple. Today, 70% global production from China (USGS Mineral Report 2025), where we lead with ISO 9001-certified lines. For your ROI-focused decisions: Clients report 37% cost reduction vs. European suppliers.
Purity grades we offer: Industrial (98%), Photo (99.5%), Pharma (99.9%+), Food (FCC). Each batch undergoes HPLC, ICP-MS testing for heavy metals <10ppm. Packaging: UN-approved for sea/air freight, with silica gel desiccants to maintain anhydrous integrity.
LSI applications: Antidote for cyanide (IV drip form), mordant in textiles, reducing agent in bleach recovery. In aquaculture, 0.1% dosing cuts fish mortality by 22% (USDA study). Dive into solutions below.
