As an accredited Calcium Carbide factory, we enforce strict quality protocols—every batch undergoes rigorous testing to ensure consistent efficacy and safety standards.
| Packing | Calcium Carbide is packaged in 50 kg net weight steel drums with airtight seals, labeled with hazard and handling instructions. |
| Container Loading (20′ FCL) | 20′ FCL container loading of Calcium Carbide involves securely packing drums or casks to maximize volume, ensure safety, and prevent moisture. |
| Shipping | Calcium carbide must be shipped in tightly sealed, moisture-proof containers to prevent contact with water, which produces flammable acetylene gas. It is classified as a hazardous material (UN 1402). Shipping regulations require labeling for flammable solid, proper documentation, and secure handling to prevent leaks, heat exposure, or physical damage during transit. |
| Storage | Calcium carbide should be stored in a cool, dry, well-ventilated area away from moisture and sources of water, as it reacts violently with water to produce flammable acetylene gas. Keep container tightly closed and clearly labeled. Store away from acids, oxidizing agents, and food items. Use sealed, moisture-resistant containers to prevent accidental contact with humidity or damp air. |
| Shelf Life | Calcium carbide typically has a shelf life of 1-2 years if stored in tightly sealed containers, dry conditions, and away from moisture. |
