As an accredited Acid Black 158 factory, we enforce strict quality protocols—every batch undergoes rigorous testing to ensure consistent efficacy and safety standards.
| Packing | Acid Black 158 is packed in a 25 kg blue fiber drum with inner polyethylene lining and clearly labeled product information. |
| Shipping | **Shipping Description for Acid Black 158:** Acid Black 158 is typically shipped in tightly sealed, moisture-proof packaging—such as fiber drums or plastic bags—to prevent contamination and moisture absorption. It should be transported under ambient conditions, away from strong oxidizers, and in compliance with local chemical transportation regulations. Handle with appropriate personal protective equipment. |
| Storage | Acid Black 158 should be stored in a cool, dry, and well-ventilated area, away from direct sunlight and sources of ignition. Keep the container tightly closed and avoid contact with strong oxidizing agents. Use corrosion-resistant storage containers. Ensure that storage conditions prevent moisture absorption and caking. Clearly label the storage area and containers for safety and easy identification. |
