Phosphoric Acid (H₃PO₄) is a versatile inorganic mineral acid primarily used across the agriculture, food, pharmaceutical, and industrial sectors. MDNR Resource offers premium-grade phosphoric acid in both food and industrial grades, with purity levels ranging from 75% to 85% depending on the application.
Our phosphoric acid is manufactured using either wet-process (from phosphate rock) or thermal-process (via phosphorus combustion), ensuring tailored specifications based on client demand. We deliver in IBC tanks, drums, or ISO tanks, supporting both small-scale and bulk B2B supply needs.
With a strong global logistics network, we ensure fast delivery and strict compliance with REACH, ISO, and SGS certifications.
1. Wet Process

1. What is the difference between food-grade and industrial-grade phosphoric acid?
Food-grade phosphoric acid is produced via the thermal process for higher purity and safety, while industrial-grade is often made through the wet process and used in fertilizers and cleaning agents.
2. Can you supply phosphoric acid globally in ISO tanks?
Yes. MDNR Resource handles global bulk shipping, including ISO tank containers for high-volume industrial clients.
3. What certifications do you provide with your phosphoric acid?
Our products are compliant with ISO 9001, REACH, SGS, and Halal certifications (where applicable).
4. Is your phosphoric acid suitable for beverage applications?
Yes. Our food-grade phosphoric acid is widely used as an acidulant in carbonated beverages and is compliant with FDA and Codex standards.
