Question about re-export and 'is APHIS is aware of specific import requirements for re-export" - Be aware that for commodities that are transiting through the USA under a re- export phytosanitary certificate, those items are not grown in the USA, nor do they qualify for consideration as a product of USA. In the case of bulbs. if the plants are not planted in the USA, the only pests would be those that attack as storage pests or opportunistic for dormant bulbs, all other plant pest association with would be with the country of production. Often the re-export phyto states for those commodities that enter the USA and then are immediately re-exported out of the USA "the plants and plant products in this shipment have meet the entry requirements of the USA at the time of import ". If the plants are only ransiting and never entering the USA often the original phytosanitary certificate says with the shipment when it changes carriers to leave the USA. The officer will stamp the paperwork 'Authorized for export only, not authorized to enter the USA". If the plants have been grown in the USA, an export phytosanitary certificate is issued and plant pests of the USA are a factor for meeting the import conditions of the receiving country.
