Phosphoric Acid
Phosphoric acid is Waking Lion's foundation product, produced by the all-thermal process from high-quality yellow phosphorus. Food and feed grade is used as an acidity adjuster, chelating agent, stabilizer, and moisture-retaining agent; a dedicated high-purity electronic grade serves circuit board etching and cleaning.
- Manufacturer since 1952 — batch-level Certificate of Analysis (COA) on every shipment
- Long-term supply contracts with committed monthly allocations, insulated from spot-market swings
- Third-party pre-shipment inspection (SGS / BV) welcomed on request

Applications
Food & Beverage
Acidity adjuster in cola-type beverages, chelating agent, stabilizer, and moisture-retaining agent in processed food.
Feed Processing
Acidity adjuster in feed processing and as a phosphorus source in feed phosphate production.
Electronics
High-purity grade for circuit board etching, cleaning, and the production of various high-quality electronic-grade phosphates.
Frequently asked questions
What is the difference between food grade and electronic grade phosphoric acid?
Food grade is controlled for heavy metals, arsenic, and fluoride under GB 1886.15-2015/FCC for use in food and feed. Electronic (high-purity) grade is controlled at ppb level across dozens of trace metals (aluminum, potassium, calcium, iron, etc.) for semiconductor and circuit board applications — a fundamentally different purity class.
What concentrations are available?
We supply 75%, 80%, and 85% H₃PO₄ as standard, with other concentrations available to customer demand.
How is phosphoric acid packaged and shipped?
35 kg or 330 kg plastic drums, iron+plastic composite drums, ISO tanks, or bulk — packaging is selected based on grade, volume, and destination port handling capability.
