Food Grade Sodium Nitrite (≥99%)
Available upon customized order only. Used as color fixative and preservative in sausage, bacon and cured meat products. Complete food safety certifications provided.
Sodium Nitrite (NaNO₂) — Essential inorganic industrial chemical for global markets
Sodium nitrite is an important inorganic industrial chemical synthesized from soda ash, liquid ammonia and nitric acid. It appears as a white crystalline solid with certain toxicity and oxidizing characteristics, categorized as Class 5.1 dangerous goods for global transportation compliance.
We supply two mainstream industrial specifications — Superior Grade ≥99% and First Grade ≥98.5% — complying with China GB/T 2367 national standard, plus customized Food Grade (≥99% purity only) available upon request. With outstanding anti-rust, antifreeze and bleaching functions, this chemical is an irreplaceable raw material for construction, metallurgy, textile printing and fine chemical industries.
With stable product quality, abundant spot stock and complete dangerous goods export documentation, our products are well-received by purchasers from the Middle East, Central Asia, Africa and Southeast Asia.

Two fixed industrial grades with uniform crystal shape and stable chemical indicators across every batch
Buyers can select grades flexibly based on downstream cost and formulation needs: high-purity 99% grade for high-end fine chemical, food processing and precise dye synthesis; economical 98.5% grade for conventional concrete antifreeze, general metal rust prevention and common textile bleaching — greatly shortening product confirmation and trial costs.
High-purity grade for fine chemical synthesis, high-end dye intermediates, precision metal treatment and food-grade customization.
Economical grade dominating bulk industrial applications — ideal for cost-sensitive procurement with stable performance.
Available upon customized order only. Used as color fixative and preservative in sausage, bacon and cured meat products. Complete food safety certifications provided.

In the competitive global inorganic chemical market, buyers focus on trustworthy long-term suppliers
We supply fixed two mature industrial grades: 99% Superior & 98.5% First Grade. Clients freely pick grades based on production cost and end-use requirements. Every batch is inspected before shipment with formal COA provided for production formula matching.
Being an essential consumable in antifreeze, anti-rust and textile bleaching industries, our two-grade products enjoy high repurchase rate after downstream factories confirm stable production formula with our material.
We hold full set of legal export certifications including MSDS, dangerous goods export permit and commodity inspection reports, meeting strict customs examination requirements of Africa, Middle East and Southeast Asian importing countries.
Supported by stable supply of raw materials including soda ash, liquid ammonia and nitric acid, we maintain sufficient year-round spot inventory for both 99% and 98.5% grades. Our sales team checks local import restriction policies in advance for nations with strict import access limits.
