How to Package Air Freight: Standards & Best Practices

Why Packaging Matters in Air Freight The experts at Private Jets Connect break down the key points below.

Packaging air freight is not a minor logistical detail – it is a decisive factor for safety, regulatory compliance, and cost control. Unlike ocean shipping, air cargo exposes goods to unique constraints: atmospheric pressure variations, sub-zero temperatures in unpressurized holds, vibrations, and acceleration forces during takeoff and landing.

Inadequate packaging can result in cargo rejection by the airline, irreversible damage, or cost overruns from volumetric weight recalculations. Every year, thousands of cargo claims are directly attributed to poor packaging.

This guide covers the standards, packaging types, and best practices for shipping your air freight with confidence.

Specific Constraints of Air Transport

Pressure and Temperature

At cruising altitude, cargo hold pressure can drop significantly. While pressurized holds maintain a controlled environment, bulk compartments experience temperatures as low as -20 C. Packaging must withstand these thermal extremes without deformation.

Vibrations and Impact

Takeoff, landing, and turbulence generate acceleration forces of up to 1.5 G forward and 9 G downward during emergency braking. Internal cushioning must absorb these impacts to protect the contents.

Dimensions and Weight

Cargo hold doors impose strict size limits. An oversized package will be rejected or require a dedicated charter flight. Always verify the maximum dimensions accepted by the airline and aircraft type before packaging.

Types of Air Freight Packaging

Reinforced Cardboard

Double or triple-wall corrugated cardboard remains the standard for general cargo shipments. It offers an excellent weight-to-strength ratio and is easily recyclable. For air shipments, choose cardboard with an ECT (Edge Crush Test) rating above 32 lb/in to ensure stacking resistance.

Wooden Crates and Plywood

For heavy or fragile cargo, wooden crates provide superior structural protection. They must comply with ISPM 15 (phytosanitary treatment) for international transport. Plywood is lighter and does not require ISPM 15 treatment.

ULD: Unit Load Devices

ULDs are the standard loading units in air cargo. They come as contoured containers (LD3, LD7, LD11) designed for aircraft holds and as pallets secured with nets. Using a ULD optimizes loading, reduces handling, and minimizes damage risk.

Specialized Packaging by Cargo Type

Certain freight categories require regulated packaging:

• Dangerous goods: UN-certified packaging compliant with IATA DGR regulations. See our guide on shipping dangerous goods by air.
• Perishable goods: insulated containers with gel packs or dry ice, compliant with IATA Perishable Cargo Regulations (PCR).
• Pharmaceuticals: GDP-qualified packaging with temperature loggers. Read our article on the cold chain in air freight.

Applicable Standards and Regulations

IATA Cargo Handling Manual

The IATA Cargo Handling Manual (ICHM) is the global reference for air freight packaging. It defines minimum requirements for packaging strength, marking, and labeling. Cargo agents verify compliance before acceptance.

ISPM 15 Standard

The ISPM 15 standard from the Food and Agriculture Organization (FAO) mandates treatment of wood packaging to prevent the spread of harmful organisms. All solid wood materials (pallets, crates, dunnage) must be treated and marked.

Marking and Labeling

Every air freight package must carry compliant labeling:

• Shipper and consignee name and address
• Air Waybill number (AWB)
• Handling labels: fragile, this way up, do not stack
• Regulatory labels for dangerous goods, perishables, or live animals

Step-by-Step Guide: Packaging Your Air Freight

Step 1: Assess Your Cargo

Identify the nature, weight, dimensions, and fragility of your goods. Determine whether they fall under a regulated category (dangerous goods, perishables, live animals, high-value items).

Step 2: Choose the Right Outer Packaging

Select packaging whose strength matches the weight and fragility of your cargo. For standard shipments, double-wall cardboard is sufficient. For heavy or sensitive freight, opt for wooden crates or flight cases.

Step 3: Secure Internal Cushioning

Cushioning is the key element of protection. Use:

• Closed-cell polyethylene foam for fragile items
• Air pillows or crumpled kraft paper to fill voids
• Cardboard corners and edge protectors to reinforce edges

Each item should be individually immobilized to prevent movement inside the package.

Step 4: Close and Reinforce

Seal the package with reinforced packing tape (minimum 50 mm wide). Apply at least three strips across each seam. For heavy crates, use steel or polypropylene strapping with buckles.

Step 5: Weigh and Measure

Calculate the gross weight and volumetric weight (L x W x H in cm / 6,000). The airline will charge whichever is higher. Compact, optimized packaging reduces volumetric weight and therefore transport costs.

Step 6: Label Correctly

Apply labels visibly on at least two sides of the package. Include all information required by the airline and shipping documents.

Common Packaging Mistakes to Avoid

Here are the most frequent mistakes observed in air freight packaging:

• Underestimating cushioning: a few centimeters of empty space is enough for cargo to shift and sustain damage.
• Using untreated wood: the package will be rejected at customs or at boarding.
• Ignoring volumetric weight: oversized packaging leads to billing above actual weight.
• Forgetting labels: a poorly identified package can be delayed, rerouted, or lost.
• Overlooking regulations: for dangerous or perishable goods, non-compliant packaging exposes the shipper to penalties and transport refusal.

Optimizing Packaging Costs

Since air freight costs are directly tied to volumetric weight, every centimeter matters. Here are proven strategies:

• Tailor packaging to exact cargo dimensions to eliminate void space
• Use lightweight materials such as honeycomb cardboard or expanded polystyrene instead of solid wood when strength permits
• Consolidate packages onto a pallet or into a ULD to benefit from grouped rates
• Work with an experienced broker like Private Jets Connect who advises on packaging optimization before each shipment

Conclusion

Air freight packaging is a specialized discipline combining regulatory requirements, mechanical protection, and economic optimization. Proper packaging ensures the integrity of your goods, compliance with IATA standards, and control over your shipping costs.
