As an accredited Sodium Chromate factory, we enforce strict quality protocols—every batch undergoes rigorous testing to ensure consistent efficacy and safety standards.
| Packing | Sodium Chromate is packaged in a 500g tightly sealed amber HDPE bottle with hazard labels, chemical information, and safety instructions. |
| Shipping | Sodium chromate is shipped as a hazardous material due to its toxic and oxidizing properties. It must be packed in secure, leak-proof containers clearly labeled with appropriate hazard warnings. Transportation is regulated; shipments require compliance with local, national, and international regulations, including proper documentation and handling by trained personnel wearing protective equipment. |
| Storage | Sodium chromate should be stored in a tightly sealed container, away from moisture and incompatible substances such as acids, organic materials, and combustible materials. Keep it in a cool, dry, and well-ventilated area, away from direct sunlight and heat sources. Storage areas must be labeled and secure, restricting access to trained personnel due to the substance's toxic and oxidizing nature. |
