Nitric Acid — Industrial Oxidizer for Nitrates & Metal Treatment
Nitric acid serves as the primary feedstock for ammonium nitrate and calcium nitrate production, metal passivation in stainless steel pickling lines, and organic nitration reactions in dye and pharmaceutical intermediates. Concentrations from 55% to 68% HNO3 are available to match downstream process requirements, with nitrogen oxides capped at 0.2% and iron at 5 ppm for colour-sensitive applications. From 100 MT.

Industrial Use
Strong oxidizer — transport and storage require dedicated acid-resistant equipment: 316 stainless steel, HDPE or glass-lined tanks. ISO tank shipments of 20–24 MT net; bulk tanker parcels from 100 MT for port-to-port delivery. FOB at chemical terminal with full SDS, COA and IMO dangerous goods documentation. HS 2808.00.
FAQ
Which concentration is standard for ammonium nitrate production?
Most AN plants specify 58–60% HNO3 for optimal neutralization efficiency and heat management. Higher concentrations (65–68%) suit transport efficiency but require dilution before neutralization.
How should nitric acid ISO tanks be prepared for return shipment?
Tanks must be passivated after discharge — rinse with water, then fill with 2–3% nitric acid solution for 24 hours to restore the protective oxide layer on stainless steel tank walls.
What are the storage temperature limits for nitric acid?
Store below 35°C away from direct sunlight and organic materials. Decomposition accelerates above 40°C, releasing nitrogen dioxide fumes that corrode tank fittings and pose inhalation hazards.
