| Packing | Anhydrous Hydrofluoric Acid is packaged in 50-liter corrosion-resistant steel cylinders with robust valve protection, labeled with hazard warnings and handling instructions. |
| Container Loading (20′ FCL) | 20′ FCL containers hold approximately 14.4MT of Anhydrous Hydrofluoric Acid, packaged in ISO tanks with proper hazardous material labeling. |
| Shipping | Anhydrous Hydrofluoric Acid must be shipped in tightly sealed, corrosion-resistant containers, such as steel cylinders with PTFE linings. It requires proper labeling as a highly toxic and corrosive substance. Transport is regulated under hazardous materials protocols, with documentation and emergency response instructions. Only trained personnel should handle shipping and receiving. |
| Storage | Anhydrous hydrofluoric acid should be stored in tightly sealed containers made of compatible materials such as polyethylene or Teflon, never glass. The storage area must be cool, dry, well-ventilated, and separated from incompatible substances. Secondary containment is advised to prevent leaks or spills. Proper labeling, restricted access, and readily available emergency equipment, such as calcium gluconate gel, are essential for safety. |
| Shelf Life | Anhydrous hydrofluoric acid typically has an indefinite shelf life if stored properly in tightly sealed containers made of compatible materials. |
