What is meaning of cargo sweat?

Answer 1

Cargo sweat means moisture (water droplets) that forms on cargo surfaces during shipping due to temperature changes.

Simple explanation:

When a container moves from a cold area to a warm, humid area, the air inside releases moisture. This moisture condenses on the cargo, making it wet — this is called cargo sweat.

Why it happens:

Temperature fluctuations during sea transport

Warm, humid air inside containers

Cold cargo or container walls

Long transit times

Problems caused by cargo sweat:

Mold & mildew growth

Rust and corrosion

Wet packaging & labeling damage

Product spoilage (food, grains, spices)

How to prevent cargo sweat:

cargo desiccants

Ensure proper container ventilation

Use moisture-resistant packaging

Avoid loading damp cargo

Answer 2

Cargo sweat refers to the condensation of moisture that occurs inside a shipping container or cargo hold due to temperature changes, particularly when warm, humid air comes into contact with cooler surfaces. This moisture can lead to the deterioration of goods, such as mold growth, rust, or damage to packaging. Proper ventilation and temperature control during transportation are essential to minimize cargo sweat and protect the integrity of the cargo.
