You will need to pay storage charges. You can have them kept at the storage facility of any cargo company here and advise them when to ship your boxes. I do not know of any such reliable companies that will take this responsibility or can be trusted. Alternatively, if you ship the boxes before your exit, the boxes will reach the port of destination long before you reach there and the goods will incur demurrage which is going to be heavy. Also, the possibilities of the goods getting damaged at the port exists as the boxes get shifted from one area to another regularly at the port.
