How to Prevent Water into Container

The port professional company has tested that there is no problem with the Container; the weather is warm and sunny during transportation; the goods are not wet when it is packed; the goods are strictly inspected when they are packed, and the water is not included. How to prevent water into container? Why does the goods come to the destination port? The goods are rusted, and who is responsible for the heavy losses?  

How to prevent water into container

(1)The cause of water   The water in the container depends on the weather conditions, the length of the voyage, the packaging of the goods, the condition of the container and the sensitivity of the goods. Fungi, mold, and mildew can cause damage to the cargo when the relative humidity exceeds 55%.   There are several types of water in the container:

1.Bring by Goods

How to prevent water into container? Moisture or moisture is brought into the container along with the cargo. For example, if a container contains 5 tons of furniture, the furniture itself will contain about 8% to 25% humidity, depending on the type of wood and the degree of drying of the furniture. This is equivalent to about 400-1250 liters of water. Some of the moisture here will be released into the air inside the container, which becomes an important source of container condensation.  

2.Container condensation

In the ocean transportation or storage process of containers, containers often experience high temperature climate and strong temperature difference between day and night. The temperature change will be 0-8 degrees Celsius and the humidity will be as high as 98%. This is the condensation phenomenon when the temperature is 30 degrees. The air content in the air is 30.4 g per square meter. When the temperature is lowered from 30 degrees Celsius to 18 degrees Celsius, water vapor will condense into water droplets. If a 40-foot container produces 1000 grams of condensed water, it will cause “container rain.”

3.Seawater infiltration

Often drifting at sea, how can the container not wet? If there is a big wind and big waves, if there is a small damage to the container, if it is on the deck, or if it encounters a sea accident and falls into the sea, it will not run into the sea or the damp. This is not much to say.

4.fresh water infusion

If the top or side panels, front panels, door panels, door rubber strips, etc. of the box are damaged, water ingress may occur during rain or snow or when the ship’s fresh water pipe is broken. Recently, the typhoon is intensive, and the north and south of the river are stormy and rainy.

1.Insurance correspondence

Freshwater Rain: One of the general additional risks, which is responsible for the compensation for losses caused by fresh water (including drinking water on board, leaking water pipes, dripping of boats, etc.), rain and snow-soluble water.

Humidity and heat insurance: Responsible for compensation for damage caused by sudden changes in temperature during the transportation of the insured goods or due to condensation, moisture or heat in the cabin due to failure of ventilation equipment on board.

WPA: It is a separate marine loss insurance. It is one of the basic risks of seaborne cargo. It is only responsible for the losses caused by salt water and is not responsible for the compensation for losses caused by fresh water.


Moisture and water damage can be prevented.

Check whether the container is sealed and dry before packing.

Confirm that the cargo and loading environment is dry;

Strengthen the waterproof packaging of goods;

Reasonably place the desiccant in the box;

Visually track the goods throughout.
