As an accredited Aluminum Oxide factory, we enforce strict quality protocols—every batch undergoes rigorous testing to ensure consistent efficacy and safety standards.
| Packing | Aluminum Oxide is packaged in a sealed 500g plastic bottle with a secure screw cap and clear hazard labeling. |
| Container Loading (20′ FCL) | 20′ FCL can load approximately 20 metric tons of aluminum oxide, packed in 25 kg or 50 kg bags on pallets. |
| Shipping | Aluminum oxide is typically shipped in sturdy, sealed bags, drums, or bulk containers to prevent moisture absorption and contamination. It is a non-hazardous material, allowing for standard shipping procedures. Proper labeling and documentation are required, and handling guidelines must be followed to minimize dust generation and ensure safe transportation. |
| Storage | **Aluminum oxide** should be stored in a tightly sealed container in a cool, dry, and well-ventilated area. Protect from moisture and incompatible substances such as strong acids and bases. Label storage containers clearly, and avoid contact with food and drink. Keep away from heat sources and handle in accordance with standard laboratory safety practices to prevent dust inhalation. |
| Shelf Life | Aluminum oxide is chemically stable with an indefinite shelf life when stored in a tightly sealed container under cool, dry conditions. |
