Hello: It seems that the England is in the Preclearance program of APHIS. http://aphis.usda.gov/import_export/plants/… And there do be the case for "May ENTER any port without inspection" in the chapter 7. But there are still some requirement for the situation. Such as the pre-cleared species is listed in the table 7-2, is dormant, with declarations "Copy-certificate of examination for USA" on the official document, and off course the phytosanitary certificate. And I'm wonder one thing. In Taiwan, the last part of the official plants inspection process is taking sample and let go. But if the sample shows the infection, then the plants be call back. (The same for the bulbs, It must take at least 10 bulbs which shows or seems have the sign of infected. for the case of geophytes, 10% of the plants need to be thoroughly inspected, and the time will varies by the species and the pests. so it may take a lot of time while there are several kinds of species which are hosts of the several pests. Each matched species and pest have its own SOP. And thank god the sample size is depends on the batch of the plants not the quantities of species.) There are cases that vegetables and meat imported to Taiwan and found they are infected by some bacteria after 1-8week (depends on the kinds and numbers of the substances which needed to be detected), just after they are eaten. Does the APHIS only let the plants go after all the samples are tested as being safe? Fierycloud Taiwan
