Quality Control

Our Phosphoric Acid, Iron Salt is manufactured under a strict quality management system. Each batch is tested to ensure it meets relevant specifications for industrial, feed, or food-grade applications, including compliance with FCC (Food Chemicals Codex) guidelines where applicable. A Certificate of Analysis (COA) detailing purity, heavy metal limits, and other critical parameters is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from incompatible materials such as strong acids and strong reducing agents. The product is hygroscopic (moisture-sensitive); ensure containers are sealed after use to prevent absorption of atmospheric moisture.
