As an accredited Needle Coke factory, we enforce strict quality protocols—every batch undergoes rigorous testing to ensure consistent efficacy and safety standards.
| Packing | Needle Coke is typically packaged in 1-ton jumbo bags, featuring moisture-proof lining, securely sealed and clearly labeled for industrial use. |
| Container Loading (20′ FCL) | Container loading (20′ FCL) for Needle Coke involves securely packing approximately 20 metric tons in jumbo bags or bulk, ensuring safe transit. |
| Shipping | Needle Coke is typically shipped in bulk containers or jumbo bags to ensure safety and prevent contamination. Packaging materials must be chemically resistant and moisture-proof. Transport is conducted via road, rail, or sea, following international hazardous material guidelines to maintain product integrity and adhere to environmental and safety regulations. |
| Storage | Needle coke should be stored in a cool, dry, and well-ventilated area, away from sources of ignition and incompatible substances. Storage facilities must prevent moisture ingress, as moisture can affect coke quality. Use covered silos, bins, or sealed containers to minimize contamination and dust generation. Ensure clear labeling and follow appropriate safety guidelines for handling carbonaceous materials. |
| Shelf Life | Needle Coke typically has an indefinite shelf life if stored in dry, cool conditions, away from moisture, contaminants, and direct sunlight. |
