Sweat and Heating

Sweat and Heating is an additional risk under marine cargo transportation insurance, covering losses to goods caused by moisture and heat during transit. It mainly applies to goods prone to moisture damage and heat deterioration, such as grain, beans, tea, tobacco, fertilizers, and timber. Usage scenarios: When goods in the ship's hold suffer sweat (hold sweat) due to poor ventilation or temperature fluctuations, or deteriorate due to exposure to high temperatures, this coverage compensates for the losses. Precautions: This risk typically cannot be insured separately; it must be added on the basis of a main coverage (such as Free from Particular Average, With Particular Average, or All Risks). Moreover, it generally only covers moisture and heat damage caused by external factors, excluding inherent defects or natural loss of the goods themselves. Differences from other terms: Unlike "Fresh Water and Rain Damage," which covers losses caused by fresh water or rain, Sweat and Heating emphasizes losses resulting from temperature changes and humidity inside the hold. Compared with "All Risks," All Risks already includes Sweat and Heating, so no separate additional coverage is needed. Foreign trade practitioners should decide whether to add this coverage based on the characteristics of the goods and the climatic conditions of the shipping route.
