How to Choose Desiccants for 20ft and 40ft Containers
Container size is not the only factor
A 40ft container has more volume than a 20ft container, but the number of desiccants needed is not calculated by volume alone. Cargo type, the initial moisture of the cargo and packaging, the shipping route, and transit duration all affect the actual quantity needed.
Information needed for an accurate recommendation
For an accurate recommendation, customers should share: cargo type and moisture sensitivity, container size (20ft or 40ft), the shipping route and expected climate, transit duration, and how cargo is stowed inside the container. CARGENTRA assesses quantity per specific shipment rather than applying one fixed number.
Frequently Asked Questions
Does a 40ft container need double the desiccants of a 20ft container?
Not necessarily. Quantity depends on multiple factors beyond volume, such as cargo type and route, so no fixed ratio applies.
