No matter in warehouse or shipping container cargo storage, all are very sensitive to cargo moisture corrosion. Such as damaging moisture will result in fading color, changing texture, geting rust and so on.

Especially in a container ocean shipping transport, there are a big moisture content in a ocean shipping container and a huge temperature fluctuation inside. Because during ocean transport, passing through different climate zones, and day to night temperature fluctuation,when air warms up, the water vapour content increase which produces condensation when the air cools down again. The central fact is that warm air is cooled, it becomes more humid, and if it is cooled enough, some of the moisture may rain out and condense directly on the shipping cargo outer package.

Drops of container rain drips down from the container roof, that will cause lots of moisture corrosion problem. Such as the salt water will change cargo’s quality and texture, like the salt water will change the density of wood characteristic, also resulting in clothes garments fading color, peeling label and so on.

Is silica gel desiccant can keep products dry such as for grain leather and metal product conquer moisture corrosion problem? Actually, we don’t recommend silica gel desiccant for cargoes with higher moisture content, such as grain leather products against moisture corrosion problem.

Even though the traditional silica gel desiccant with very cheap price, but its moisture absroption capacity is very limited. Silica gel desiccant with lower moisture absorption capacity for less than 10% moisture of its own weight, and will stop working entirely after 2 weeks.

We recommend TOPDRY calcium chloride desiccant with powerful moisture absorption capacity and longer absorption period, will be the best moisture drying agent for cargoes against moisture corrosion, such as for grain rice, cocoa beans or industrial products such as leather or metal cargoes against humidity problem.

* Become Solid Once Absorbing Moisture From Air, Leakage Free And Low Revaporization Rate

TOPDRY Container Desiccant is combine with active ingredients food grade binding agent, will become solid gel once absorb moisture vapor from the surrounding air and will not leak or escape.

What’s more, unlike traditional calcium chloride container desiccant, will trun to liquid form water, increase liquid leakage and water revaporization problem.

* -20℃ to +90℃ Operating Temperature Range, Suitable For Shipping Container.

TOPDRY Container Desiccant’s operating temperature range is -20℃ to +90℃, suitable for shipping container conquer moisture problem. While other traditional desiccant, such as silica gel desiccant, Once the temperature rise above 40℃, the water already absorbed by silica gel will re-evaporate to the air and may damage the cargo again.

* Good Quality Double Package protection

All TOPDRY Desiccant are packed with double package protection material, inner bag is composite membrane(composite membrane’s tight pore structure keeps even the smallest of particulate through the package, but the water vapour can through it freely);

Outer package is non-woven to protect package inside and outside.

What’s more, TOPDRY container desiccant are packed with PE bag individually.

* Non toxic material

We guarantee all TOPDRY Desiccant are 100% non-toxic brand new material .
All TOPDRY desiccant are DMF Free desiccant, get REACH, ROHS certification from SGS, TUV, EUROFINS. compliant with international desiccant standard.

All TOPDRY Desiccant are harmless and environmentally friendly, can be disposed as regular waste when removed from shipping container or cargo box, so no special handling or manpower are required.

Product Comparison

TOPDRY Desiccant VS Traditionaly Desiccant

Traditional desiccant, like silica gel desiccant with only 10% moisture absorbent capacity of its own weight and 14 days absorption period. What's worse, the already absorbed moisture by silica gel desiccant will start to re-evaporate if the surrounding temperature rise over 40 degree centigrade, and that will cause a big moisture damage problem. And in a shipping container, it is very usual that the temperature inside a container will rise over 60 degree centigrade.

Due to the low moisture absorbent capacity and limited working temperature range of silica gel desiccant, we can declare that silica gel is not suitable for moisture absorbent in a shipping container.

If your cargo suffer from moisture damage, why not give TOPDRY Desiccant a chance to show you.

Since travel time, weather conditions, temperature variations and final destination, shipping cargo type may significantly affect the levels of humidity encountered during the voyage, please consult us for more information.


Check if there is damage with the container, for example, if there is hole or crack at the sides, top or bottom of container.


Check container floor moisture contain (MC), a high MC in excess of 20% can increase risk of moisture damage. If the nature of containers can’t be changed.
It is necessary to increase the quantity of TOPDRY Container desiccant based in the amount of water contain in container to ensure the safety of goods.


Seal all the ventilating holes.
