As an accredited Antimony Trisulfide factory, we enforce strict quality protocols—every batch undergoes rigorous testing to ensure consistent efficacy and safety standards.
| Packing | Antimony Trisulfide, 500g, is packaged in a sealed HDPE bottle with a secure screw cap, labeled with hazard warnings. |
| Shipping | Antimony Trisulfide should be shipped in tightly sealed, labeled containers, away from incompatible substances like oxidizers and acids. It must be handled as a hazardous material according to local and international shipping regulations (e.g., IMDG, IATA). Protect from moisture, physical damage, and sources of ignition during transit. |
| Storage | Antimony trisulfide should be stored in a cool, dry, and well-ventilated area, away from sources of ignition and incompatible materials such as oxidizers and acids. Keep the container tightly closed and clearly labeled. Protect from moisture and physical damage. Use non-sparking tools and ensure proper grounding and bonding if transferring large quantities to prevent static discharge. |
