There is a risk of cargo sweat if warm moist air is introduced into the hold.
Cargo, packaging material) to react to the moisture content of the air by absorbing or releasing water vapor. This will result in cargo getting caked or rotting.

A hygroscopic cargo is defined as a cargo _____. There is danger of heavy cargo sweat if you ventilate. Cargo with a high fibrous construction (such as cotton, apparel, jewelry boxes, etc.) will hold a certain amount of moisture at origin that can be released under the right cooling conditions. I the air in the cargo hold has high relative humidity in comparison with the moisture content of the cargo, then the cargo will absorb moisture from the air.

This water vapour condenses on the container walls and ceiling which is cooled by nocturnal radiation. Cargo sweat happens when warm, moist air penetrates into a hold and condenses on the exposed surfaces of colder cargo. High air temperatures in the container and the associated low relative humidity drive water vapour out of the hygroscopic cargo. As the containerization of general cargo transport gained momentum, it extended to ever more types of cargo, including those requiring high levels of care on a conventional general cargo ship, so raising new issues with regard to the extent and effectiveness of measures to maintain the quality of the goods being.
