To ship dry ice effectively and safely, pack it within an EPS foam container inside a sturdy corrugated cardboard box, ensuring the contents you're cooling don't directly touch the dry ice.
Here's a more detailed breakdown of the process:
Essential Steps for Shipping Dry Ice:
-
Choose the Right Container:
- EPS Foam Container: Use an expanded polystyrene (EPS) foam container, also known as a Styrofoam container, for its excellent insulating properties. This will help slow down the sublimation of the dry ice.
- Corrugated Cardboard Box: Place the EPS foam container inside a sturdy corrugated cardboard box. This provides structural support and protection during transit.
-
Isolate Your Contents:
- Separate Dry Ice and Contents: Avoid direct contact between the dry ice and the items you're shipping. The dry ice is only there to maintain a cold environment. This prevents the contents from freezing solid or being otherwise damaged.
-
Proper Ventilation:
- Crucially Important: The packaging must allow for the release of carbon dioxide gas as the dry ice sublimates. Do not seal the container airtight. A completely sealed container can build up pressure and explode.
-
Quantity Considerations:
- Use Enough, But Not Too Much: Calculate the appropriate amount of dry ice needed to keep your items frozen or chilled during the expected transit time. Overusing dry ice is unnecessary and can increase shipping costs. Underusing it can result in your items thawing.
-
Labeling and Documentation:
- Regulations Vary: Shipping regulations for dry ice vary by carrier (e.g., FedEx, UPS, USPS) and destination (domestic vs. international). Always check the specific regulations for your chosen carrier and destination.
- Proper Labeling: The package must be clearly labeled with the following information:
- "Dry Ice" or "Carbon Dioxide, Solid"
- Net weight of the dry ice in kilograms
- Hazard Class 9 label (Miscellaneous Dangerous Goods)
- Shipper and recipient information
-
Shipping Carrier Considerations:
- UPS: UPS requires a dry ice agreement for shipments exceeding 5.5 lbs. UPS Dry Ice
- FedEx: FedEx requires specific packaging and labeling. FedEx Dry Ice
- USPS: USPS has specific regulations for domestic and international dry ice shipments. USPS Dry Ice
- Safety Precautions:
- Handle with Care: Always handle dry ice with insulated gloves or tongs to prevent burns.
- Ventilated Area: Pack and unpack dry ice in a well-ventilated area to avoid carbon dioxide buildup.
By following these steps, you can safely and effectively ship items using dry ice. Remember to consult the specific guidelines provided by your chosen shipping carrier before sending your package.
