As an accredited Black NR factory, we enforce strict quality protocols—every batch undergoes rigorous testing to ensure consistent efficacy and safety standards.
| Packing | Black NR is packaged in a sturdy, sealed 25 kg fiber drum with a secure lid and clear chemical labeling. |
| Shipping | Black NR should be shipped in tightly sealed containers, away from incompatible materials such as strong oxidizers. Store in a cool, dry, and well-ventilated area, avoiding direct sunlight and moisture. Ensure packaging prevents leakage or contamination. Follow all relevant local, national, and international transport regulations and label containers correctly. |
| Storage | Black NR should be stored in a tightly sealed container, away from incompatible substances such as strong oxidizers and acids. Keep it in a cool, dry, and well-ventilated area, protected from moisture and direct sunlight. Ensure the storage area is equipped with appropriate spill containment and fire suppression systems, and that all containers are properly labeled according to regulatory requirements. |
