As an accredited Indigo factory, we enforce strict quality protocols—every batch undergoes rigorous testing to ensure consistent efficacy and safety standards.
| Packing | Indigo is packaged in a 500g sealed, high-density polyethylene bottle with a tamper-evident lid, clearly labeled with safety information. |
| Shipping | Indigo is shipped as a non-hazardous dye, typically packed in fiber drums, bags, or cartons, clearly labeled and sealed to prevent moisture exposure. It should be kept dry and stored away from strong oxidizers. During transport, standard precautions for dust control and spill prevention are followed. |
| Storage | Indigo should be stored in a cool, dry, and well-ventilated area, away from direct sunlight, heat sources, and moisture. Keep it in tightly sealed containers to prevent contamination and exposure to air. Store away from strong oxidizing agents and acids. Clearly label containers, and ensure safe, secure storage to minimize environmental and health risks. Follow all applicable safety regulations. |
