Tin Ingot Storage Conditions – Professional Guidelines​​

​​1. Environmental Conditions​​

​​A. Temperature Control​​

• •
  ​​Recommended Range:​​ ​​15°C to 30°C (59°F to 86°F)​​
• •
  ​​Avoid:​​
  • •
    ​​Extreme Heat (>40°C / 104°F)​​ → Accelerates oxidation and surface degradation.
  • •
    ​​Freezing Temperatures (<10°C / 50°F)​​ → May cause brittleness in some alloys.

​​B. Humidity Control​​

• •
  ​​Relative Humidity (RH):​​ ​​<60% (ideally 30-50%)​​
• •
  ​​High Humidity (>70% RH) Risks:​​
  • •
    ​​Accelerated oxidation​​ (tin reacts with moisture & oxygen).
  • •
    ​​Tarnishing & surface discoloration.​​
• •
  ​​Solution:​​ Use ​​dehumidifiers​​ or ​​dry storage rooms​​ if necessary.

​​C. Ventilation​​

• •
  ​​Good Air Circulation​​ → Prevents moisture buildup.
• •
  ​​Avoid:​​ ​​Stagnant, damp, or poorly ventilated areas.​​

​​2. Packaging & Protection​​

​​A. Original Factory Packaging (Best Practice)​​

• •
  ​​Kraft Paper + Vinyl Coating​​ → Protects against oxidation.
• •
  ​​Oil-Coated Surface​​ → Slows down tarnishing.

​​B. Secondary Packaging (For Long-Term Storage)​​

• •
  ​​Wooden Pallets / Crates​​ (ISPM 15 compliant for export).
• •
  ​​Polyethylene Wrapping / Shrink Film​​ → Additional moisture barrier.
• •
  ​​Desiccants (Silica Gel Packs)​​ → Absorbs excess moisture.

​​C. High-Purity Tin (99.99%+)​​

• •
  ​​Vacuum-Sealed Bags​​ → Prevents air exposure.
• •
  ​​Argon Gas Purging​​ → Inert atmosphere storage.
• •
  ​​Sealed Metal Containers​​ → Extra protection against oxidation.

​​3. Storage Location & Handling​​

​​A. Ideal Storage Area​​

• •
  ​​Dry, Clean, & Well-Ventilated Warehouse.​​
• •
  ​​Away from:​​
  • •
    ​​Chemicals (acids, sulfides, chlorine compounds).​​
  • •
    ​​Direct Sunlight & Rain Exposure.​​
  • •
    ​​Corrosive Materials (e.g., copper, lead, steel).​​

​​B. Stack Height & Weight Distribution​​

• •
  ​​Maximum Stack Height:​​ ​​3 layers (≤1200 kg total).​​
• •
  ​​Avoid Overstacking​​ → Prevents deformation & damage.

​​C. Handling Precautions​​

• •
  ​​Use Gloves & Clean Tools​​ → Avoid contamination.
