As an accredited Sodium Sulfide factory, we enforce strict quality protocols—every batch undergoes rigorous testing to ensure consistent efficacy and safety standards.
| Packing | Sodium Sulfide is packaged in a 25 kg tightly sealed, yellow HDPE drum with a corrosion-resistant inner liner and hazard labeling. |
| Shipping | Sodium sulfide must be shipped in tightly sealed, corrosion-resistant containers, clearly labeled with hazard warnings. It should be kept away from acids, moisture, and incompatible substances, and transported as a hazardous material according to local, national, and international regulations, such as UN1849, Class 8 (corrosive), with appropriate emergency response instructions included. |
| Storage | Sodium sulfide should be stored in a cool, dry, well-ventilated area away from moisture, acids, and incompatible substances. Containers must be tightly sealed, clearly labeled, and constructed from materials resistant to corrosion. Avoid exposure to heat and humidity, as sodium sulfide is hygroscopic and can release toxic hydrogen sulfide gas upon contact with acids or water. |
