Quality Control

Our Manganese(II) Fumarate is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for purity, heavy metal content, and microbiological limits. Certificates of Analysis (COA) documenting compliance with relevant standards, including feed grade and FCC guidelines where applicable, are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed to prevent absorption of atmospheric moisture. For long-term storage, consider using desiccants or an inert atmosphere to minimize oxidation.
