Answer: Because there are strict regulations on the arrival date of exhibits abroad, in order to ensure that there is enough time for customs clearance, the exhibitors should prepare exhibits as soon as possible, usually to arrive at the destination port from 15 to 30 working days before launching. Generally, exhibitors should prepare exhibits in advance and ship them smoothly by adding half to one month to the normal shipping time. If the goods are to be transported by air, they should be ready for shipment within the normal time plus 15 days.
