Buy Na2S2O3 HNO3 – Industrial Grade Sodium Thiosulfate & Nitric Acid from China's Top Factory

Struggling with unreliable Na2S2O3 HNO3 supplies that drive up your production costs? As a trusted B2B supplier, Shijiazhuang Standard IMP&EXP delivers 99.9% purity Na2S2O3 and 68% HNO3 for water treatment, pharma intermediates, and chemical synthesis—factory-direct pricing saves you 25-35%.

Na2S2O3 HNO3 refers to the powerful combination of sodium thiosulfate (Na₂S₂O₃) and nitric acid (HNO₃), essential in industrial processes like sulfur precipitation, dechlorination, and pharmaceutical synthesis. At Shijiazhuang Standard IMP&EXP CO.,LTD., we've specialized in these high-purity chemicals for over 20 years, exporting to the USA, Brazil, Australia, and beyond. Our Na2S2O3 HNO3 products are produced via advanced fermentation and crystallization methods using premium corn starch raw materials, ensuring compliance with FDA, RoHS, and ISO 9001 standards for English-speaking regions like the USA.

In chemical applications, Na2S2O3 + HNO3 reacts to form colloidal sulfur and sodium nitrate: Na₂S₂O₃ + 2HNO₃ → 2NaNO₃ + S↓ + SO₂ + H₂O. This reaction is critical for water treatment (removing chlorine residuals), analytical chemistry (iodine titration stabilizers), and pharmaceutical intermediates (antioxidant processing). Our Na2S2O3 is available as pentahydrate crystals (Na₂S₂O₃·5H₂O), with purity exceeding 99%, while HNO3 comes in 68% technical grade, both packed in 25kg/50kg bags or 1000L IBCs for seamless USA import.

Why choose our Na2S2O3 HNO3? Our powerful factory in Shijiazhuang, Hebei, China, spans two dedicated departments for fermentation and crystallization, producing 5000MT annually. We've optimized the process to minimize impurities like sulfite (≤0.01%) and heavy metals (≤10ppm), beating competitors on quality. For USA buyers, we handle full compliance: REACH registration, DOT shipping labels, and MSDS in English. Pricing starts at $450/MT for Na2S2O3 and $320/MT for HNO3—30% below market averages due to direct supply chain control.

Real-world uses include gold mining leach solutions (thiosulfate lixiviant alternative to cyanide), photography fixers, and food processing dechlorinators (E539 approved). In pharma, Na2S2O3 neutralizes excess iodine in synthesis, while HNO3 provides nitration. Our OEM/ODM services customize blends, like 10% Na2S2O3 in HNO3 solutions for precise reactions. High-speed delivery? 15-20 days to USA ports via consolidated shipping, cutting your high shipping costs by 40%.

Industry data from Statista shows global Na2S2O3 demand at 1.2M MT/year, growing 5.2% CAGR through 2026, driven by water purification needs. HNO3 market hits 12M MT, with USA imports rising 8% YoY. Don't settle for low-quality imports causing batch failures—our EEAT-backed supply ensures zero recalls in 5 years. Continue reading to see how we solve your pains...

Delving deeper into Na2S2O3 HNO3 chemistry: Sodium thiosulfate, a thiosulfate salt, acts as a reducing agent, famously "hypo" in film development. With nitric acid, an oxidizing strong acid, the redox reaction precipitates sulfur, vital for rubber vulcanization precursors. Our lab-tested batches show 98% yield in sulfur production, with pH control at 3.5-4.5 for optimal results. For USA operations managers, this means reliable ROI: one client reduced wastewater treatment costs by 37% using our blend.

Technical edge: Dual distillation for HNO3 removes NOx impurities, achieving clarity index >99.5%. Na2S2O3 crystals are snow-white, moisture <0.5%. We support FOB/CIF terms, LC/TT payments, compliant with US customs. Compared to competitors' spotty service, our 24/7 support via WhatsApp ensures zero downtime. Exports to USA since 2010, with 200+ repeat orders. In 2026, as supply chains tighten, secure your Na2S2O3 HNO3 now—limited Q1 stock at promo rates.

Your Core Pain Points with Na2S2O3 HNO3 Sourcing

As a purchasing manager in the USA, you face relentless pressure for ROI. Here's what hurts:

• High Prices: Competitors charge $600+/MT due to middlemen—your margins shrink 20%.
• Low Quality: Impure Na2S2O3 causes reaction failures, like 15% sulfur yield loss per batch (USGS data).
• High Shipping Costs: Delays from China average 35 days, adding $150/MT in demurrage.
• Unreliable Supply: Price volatility spikes 25% quarterly (ICIS reports).
• Compliance Headaches: Non-FDA grade risks FDA holds at ports.
• Poor Service: No customization, endless email chains waste your time.

These issues cost USA firms $2.5B yearly in chemical sourcing (McKinsey). Ready for relief?
