Container desiccant is a line of specially designed cargo desiccants aimed at protecting cargo during shipping by aggresively absorbing moisture from the air. In doing so, the desiccants reduces dew point temperature, prevent condensation and protect the cargo.
There is, indeed, no rational reason today why anyone shipping goods in containers should avoid the use of desiccants, given that, for a cost of US$80 or less, an entire consignment - often worth many hundred times more - can be protected from all types of condensation damage. This can range from mould-infestation/rusting of metal products or lables peeling free, at the very least to total spoilage and a complete write-off of the freight value. Very few shipments are immune to the effects while eve then mildest deterioration can render the product unfit for sale after delivery to the consignee.
