Cold chain products require specialized shipping to maintain quality and viability.
Temperature requirements by product type
Ultra-low (-80°C to -20°C):
- Frozen cell lines
- Certain enzymes and proteins
- Some reagents
Refrigerated (2-8°C):
- Some growth factors
- Ready-to-use media
- Certain supplements
Shipping methods
Frozen shipments:
- Pack in validated insulated containers
- Use sufficient dry ice (typically 2-5 kg per day of transit plus 24-hour buffer)
- Include temperature indicator cards or data loggers
- Mark as "Dry Ice - Frozen Biological Material"
- Ship via express service (24-48 hour delivery)
- Coordinate delivery timing with buyer
Refrigerated shipments:
- Use insulated containers with gel packs
- Include temperature indicators
- Ship via express or priority service
- Avoid weekend delivery when possible
Documentation requirements
Include with cold chain shipments:
- Certificate of Analysis with storage temperature
- Temperature indicator status guide
- Immediate handling instructions
- Viability guarantee terms
- Your contact information for immediate temperature excursion reporting
Validation
Maintain documentation showing:
- Shipping container validation data
- Temperature stability during typical transit times
- Seasonal adjustments to packaging
Delivery coordination
For high-value or critical cell lines:
- Email buyer with expected ship date
- Provide tracking information immediately
- Request confirmation of receipt
- Be available to troubleshoot temperature issues
Temperature excursion protocol
If buyer reports temperature indicator showing excursion:
- Request photo of temperature indicator
- Review shipment timeline
- Assess likely impact on product
- Offer replacement if quality is compromised
- Investigate cause to prevent recurrence
Quality guarantee
Standard practice for cell line suppliers:
Guarantee viability if:
- Temperature indicator shows acceptable range
- Product opened and used within specifications
- Handling followed instructions
Replace at no charge if:
- Temperature compromised during shipping
- Product defective as shipped
- Viability below specified percentage
