If it has been fumigated, the fumigation team will stamp the fumigation mark on the wooden box.
Under normal circumstances, the fumigated package will be shipped within 60 days (I remember this time) There is no need to re-fumigate for re-export, but in fact, if the time is longer, as long as the packaging is not damaged or moldy, it doesn’t matter if you don’t fumigate.
However, the date of your fumigation certificate does not meet the requirements. If a fumigation certificate is required abroad, you will have to re-fumigate.
