An International Air Freight Forwarder’s Guide to Save Goods from Moisture Damage

Imagine you’re an organization that transports commodities from one location to another. You’ll be shipping some meat from China to Canada via an international air freight forwarder. The meat is carefully put onto the freight aircraft after being adequately refrigerated in its special shipment container.

The pilots have a smooth flight with no disturbances or mechanical failures on board. The cargo attendants are stunned by the strong fragrance of decomposing meat when the plane eventually lands at its destination. Under unknown circumstances, the entire container has been ruined. The product was most likely harmed by dampness. This is one of the most prevalent perishable complaints according to the most international air transport services provider.

According to the most reputed international air freight forwarder, moisture-related and contamination, both of which are caused primarily by moisture penetration, account for around 11% of shipment damage claims.

The excellent news is that protecting your commodities from moisture damage is straightforward and easy. All you have to do now is prepare your cargo containers with the appropriate equipment. Everything that you need to learn about preventing the absorption of moisture in air freight is right here.

What Causes Moisture Damage?

It pours when it rains, and this is particularly the case when transporting freight. A concept called “container rain” occurs when a high amount of moisture accumulates inside a shipping container. Water particles attach to the container’s roof and walls gradually start “raining” down on the products you’re shipping. The term “container sweat” is often used to represent it.

So, what exactly produces container moisture? As per RU Air Freight, an international air freight company temperature fluctuations, humidity, and leakage are the basic reasons.

Temperature Shifts

The leading cause of container moisture is simple variation in the temperature. Any moisture within the cargo container will condense and convert into water drops as the temperature falls from warm to icy. Since the temperature in the sky is constantly colder than the temperature on the land, condensation is actually very common in airline freight containers. After the plane lifts off, moisture will occur almost instantly.


Warm air has a higher moisture content than cooler air. If you’re shipping freight from a humid area, it’s much more likely to be damaged by humidity. When you’re packing cargo containers with goods, it might be tough to keep heated air out. When putting cargo containers into cargo planes, heated air can readily get into the cargo compartment.


Goods getting damaged from moisture are especially likely in containers containing perishable goods. In transportation, perishable items must be frozen or chilled. If the storage containers have any gaps, the moisture content that drips inside the container would be higher. Air freight with leaking fish, vegetable, and meat containers can result in significant cargo rain, which can lead to contamination by triggering bacterial growth. This is what makes transporting perishable material so challenging.

How to Avoid Moisture Damage in Air Cargo?

So, what is the solution to avoid moisture damage in air freight? The easiest approach according to most international air transport services to avoid moisture damage is to use materials that decrease or minimize condensation in your containers. Here are a few helpful strategies to consider.

  • Choose the Right Pallets
  • Use Absorbent Pads
  • Absorb Moisture with Desiccants

Summing Up

When hiring an international air freight company, container rain is almost inevitable. Rust and item damage can result if your products are not effectively protected against moisture, particularly if they are perishable and consumable.

To safeguard your air cargo from moisture penetration, all you have to do is dehumidify your cargo containers with blankets, absorbent pads, and desiccants. The simplest way to implement air freight moisture damage avoidance is to use these items in storage containers, particularly when transporting sensitive cargo.
