Sodium Nitrite (NaNO₂) — Versatile inorganic salt for global industrial markets
Sodium nitrite (NaNO₂) is an essential inorganic industrial chemical with anti-rust, antifreeze and bleaching functions. It appears as white crystalline solid or powder and is classified as UN 1500 Class 5.1 oxidizer — we supply complete dangerous goods export documentation for global B2B buyers.
We supply two mainstream industrial specifications — Superior Grade ≥99% and First Grade ≥98.5% — with stable chemical indicators and uniform appearance across every batch. Widely applied in concrete antifreeze, metal anti-rust, textile bleaching, pharmaceutical diazotization and fine chemical synthesis.
With stable product quality, abundant spot stock and full DG export documentation (MSDS, COA, UN 1500 packing certificate), our products are well-received by purchasers from Europe, the Middle East, Central Asia, Africa and Southeast Asia.

Two fixed industrial grades with multiple physical forms for flexible downstream formulation
Buyers can select grades based on application and cost requirements: Superior Grade ≥99% for fine chemical synthesis, precision metal treatment and food-grade customization; First Grade ≥98.5% for concrete antifreeze, bulk metal anti-rust and conventional textile bleaching — greatly shortening product confirmation and trial costs.
High-purity grade for fine chemical synthesis, precision metal treatment, high-end dye intermediates and food-grade customization.
Economical bulk grade dominating industrial applications — ideal for cost-sensitive procurement in construction and metallurgy.
