What is the Basic Requirement for Dry Ice Air Shipment?

Dry ice must be packaged in vented containers that allow CO₂ gas to escape. This is crucial to avoid pressure buildup which could cause explosions. بالإضافة إلى ذلك, the package must be labeled correctly with the proper shipping name (“الجليد الجاف” أو “ثاني أكسيد الكربون, صلب”) and the UN 1845 number. These requirements are part of the IATA’s Packing Instruction 954 (باي 954), which remains the gold standard for dry ice air shipments in 2025.

What Packaging Materials and Methods Should You Use?

• العزل: Use materials like EPS foam or vacuum-insulated panels (VIP) for optimal thermal insulation. VIPs are more efficient but costlier.

• تنفيس: Ensure that the outer container is not airtight. Use vent holes or leave flaps slightly open for proper gas release.

• Layering Strategy: Place dry ice around the product, separated by protective layers like cardboard or foam, ensuring that the dry ice doesn’t directly contact sensitive goods.

Step-by-Step Packing Process

1. Pre-cool your products: Ensure your goods are pre-frozen to reduce thermal load.

2. Choose the right insulation: Select EPS foam or VIP for optimal dry ice retention.

3. Pack dry ice: Place the dry ice around but not in direct contact with the product.

4. Seal and vent the container: Leave small gaps or use vented flaps to allow CO₂ to escape.

5. Label correctly: Affix the Class 9 تسمية الخطر, "الجليد الجاف" أو "ثاني أكسيد الكربون, صلب,” UN 1845, والوزن الصافي.

Key Regulations for Dry Ice Air Shipments in 2025

Marking and Labeling:
For all shipments, the following must be clearly visible:

• فصل 9 تسمية الخطر

• و 1845

• Net weight of dry ice in kilograms (كجم)

إعلان الشاحن:
في معظم الحالات, when shipping dry ice without other hazardous goods, a full Shipper’s Declaration is not required. لكن, for shipments containing dangerous goods (DG), a full declaration is needed.

Carrier-Specific Rules:
Different airlines and carriers may impose additional limitations, such as maximum dry ice weight per package or specific requirements for container materials. Always verify with your carrier for route-specific rules.

How Much Dry Ice is Needed for Air Shipments?

To determine the correct quantity of dry ice, follow this formula:

• Base Sublimation Rate: 5-10 رطل لكل 24 ساعات, depending on insulation quality.

• المخزن المؤقت: Always add 20-25% extra to cover unexpected delays or changes in route conditions.

على سبيل المثال, for a 48-hour shipment, you would need approximately:

• 6 lb/day x 2 days = 12 رطل

• يضيف 25% buffer = 2.4 رطل

• Total dry ice required: 14.4 رطل (~6.5 kg)

Special Considerations for Dry Ice Quantities

• Passenger Shipments: فقط 2.5 kg of dry ice per passenger is allowed (with carrier approval).

• Cargo Shipments: The maximum dry ice allowed is 200 kg per package, though airlines may set lower limits.

Dry Ice Air Shipment Documentation

When shipping dry ice, the following documentation is required:

• على شعب الطريق (AWB) مع:

  • و 1845

  • اسم الشحن الصحيح (“الجليد الجاف” أو “ثاني أكسيد الكربون, صلب”)

  • وزن صافي of dry ice in kg

• قائمة التحقق من القبول: Follow the 2025 carrier dry-ice checklist to ensure all regulations are met.

What to Avoid When Packaging Dry Ice

• Avoid airtight containers: This can cause pressure to build up and lead to ruptures.

• Don’t skimp on insulation: Poor insulation accelerates sublimation, increasing dry ice consumption and risks.

• Ensure clear labeling: Incorrect or missing labels can cause delays or rejections.

• Don’t ignore carrier-specific requirements: Each carrier might have additional rules—always check before shipping.

2025 Trends in Dry Ice Air Shipments

Hybrid Cooling Systems:
Combining dry ice with phase change materials (PCMS) is emerging as a popular solution to reduce waste and ensure precise temperature control. This is particularly useful for shipments requiring temperatures that dry ice alone cannot maintain.

العبوة الذكية:
Smart sensors integrated into packages to monitor temperature and CO₂ levels are becoming more common, providing real-time data to optimize shipping processes and prevent issues before they occur.

التركيز على الاستدامة:
As part of the growing trend for sustainable logistics, eco-friendly refrigerants like biodegradable gel packs and PCMs are being adopted as alternatives to dry ice in some air shipments.

دراسة حالة: Biotech Shipment Success

A biotechnology company reduced spoilage by 25% and avoided regulatory violations by switching from traditional tight-sealing coolers to vented packaging kits. This change led to fewer shipment holds and improved on-time delivery within one month.

الأسئلة المتداولة

س 1: How long will dry ice last in a properly packaged air shipment?
Dry ice typically lasts 24–72 hours, depending on insulation and sublimation rate. Always factor in a buffer for delays.

Q2: Can I ship dry ice with gel packs in the same package?
نعم. Ensure dry ice is separated from gel packs with protective layers to avoid freezing sensitive products.

س 3: Is a Shipper’s Declaration needed for dry ice shipments?
Only if shipping dangerous goods with dry ice. For non-DG shipments, ensure proper labeling and documentation.

Conclusion and Action Plan

To successfully package dry ice for air shipment, follow these key steps:

1. Use vented, insulated packaging to allow CO₂ gas to escape.

2. Accurately calculate dry ice requirements and add a 20–25% buffer.

3. Label and mark your packages according to IATA 2025 المبادئ التوجيهية.

4. Stay updated with carrier-specific rules and regulatory changes.
