| Packing | The packaging for Tannin is a sturdy, sealed plastic drum labeled “Tannin,” containing 25 kilograms, with safety handling instructions displayed. |
| Storage | Tannin should be stored in a cool, dry, and well-ventilated area, away from direct sunlight and moisture. Containers must be tightly sealed to prevent exposure to air, as tannins can absorb moisture and degrade. Use corrosion-resistant containers, such as those made of glass or plastic. Keep away from strong oxidizing agents and acids to avoid chemical reactions and contamination. |
| Shipping | Tannin should be shipped in well-sealed, labeled, and chemically-resistant containers to prevent moisture absorption and contamination. Store and transport it in a cool, dry, and well-ventilated area, away from incompatible substances.
