Moisture Risk Management in Import–Export

Shipping containers move across multiple climate zones. When warm, humid air trapped inside the container cools, water vapor condenses on interior surfaces. This condensation eventually drips onto cargo, commonly known as “container rain. Cargo desiccants are engineered moisture-control solutions designed for container-level protection. They work by continuously absorbing water vapor, preventing dew point formation, and locking moisture into gel or crystalline structures to avoid re-release. Unlike conventional silica gel sachets, cargo desiccants are designed to absorb large volumes of moisture over long sea voyages.
