As an accredited Calcium Dithionite factory, we enforce strict quality protocols—every batch undergoes rigorous testing to ensure consistent efficacy and safety standards.
| Packing | Calcium Dithionite is packed in a 25 kg white plastic drum with a secure lid, labeled with hazard symbols and handling instructions. |
| Shipping | Calcium Dithionite must be shipped in tightly sealed containers, protected from moisture and oxidizing agents. It should be stored in a cool, dry place and handled with care to avoid decomposition and release of sulfur dioxide. Shipping must comply with relevant hazardous material regulations due to its reducing and potentially unstable properties. |
| Storage | Calcium Dithionite should be stored in a cool, dry, and well-ventilated area, away from heat, moisture, and incompatible substances such as acids and oxidizers. Keep the container tightly closed and protected from direct sunlight. Use non-sparking tools and prevent contact with water to avoid decomposition. Store in labeled, corrosion-resistant containers and follow standard chemical storage protocols. |
