Characteristics
Some large cased goods, e.g. C.K.D. (cars knocked down), may be stored outside prior to shipment. Thus, the crates (and sometimes the contents) are wet or damp on shipment and introduce moisture into the hold, container, etc., to the detriment of other cargo. Very large cases of construction equipment may be moved great distances after discharge the packaging is most important for the protection of the contents as well as sometimes having a subsequent use as storage or even temporary accommodation. It should also be noted that crates or cases holding machinery may leak oil.
