Other documentation may be required, such as some countries may need the permit numbers included on the cargo manifest.
Shippers should always mark what is contained in the packaging and whether dry ice is used because it is classified as a dangerous goods. Then the packaging should be correctly labeled with the standard IATA label as such: "perishable," "this way up," or "wet cargo."
Packaging for shipping perishable goods
There are a wide array of perishable goods, and they are each subject to deterioration, some faster than others. Appropriate packaging and handling are crucial to the perishable goods being delivered in good condition.
The packaging must facilitate both the integrity of the goods as well as the handling and storage of the goods.
The packaging must meet food safety regulations and meet food-grade standards while still being durable enough to withstand temperature changes and stacking. A lot goes into creating proper packaging for perishable goods. You can find more information about the specific structures in Chapter 5 of the IATA PCR.
