Moisture damage is one of the most common challenges faced during sea freight. When warm, humid air inside a container meets a cold surface, condensation forms, often referred to as “container rain” or “cargo sweat.” This can lead to Mold, rust, and product deterioration.

Here are five practical ways to prevent it:
1. Use High-Quality Desiccants Desiccants absorb moisture from the air inside containers, keeping humidity levels stable. Products like silica gel, clay, or calcium chloride desiccants can make a significant difference.

2. Ensure Proper Ventilation Containers should allow airflow to balance temperature and humidity. Avoid blocking air vents with cargo.

3. Dry Cargo Before Loading Even slightly damp packaging or pallets can release moisture during transit. Always ensure goods are fully dry.

4. Use Moisture Barriers Apply plastic liners or VCI films to act as a barrier against condensation and external humidity.

5. Monitor Temperature and Humidity Data loggers or sensors can help identify risky conditions before damage occurs.

By combining these methods, companies can significantly reduce the risk of moisture-related losses, ensuring goods arrive in optimal condition.
