Yes, they can be combined because AliExpress allows multiple orders from the same person to be combined. Just select the combined shipment option when placing an order. This can save postage costs and avoid receiving multiple packages at the same time. However, it should be noted that orders for combined shipments must be placed at the same time and have not been shipped. If one order has already been shipped, then combined shipments cannot be made. In addition, for cross-border e-commerce orders, you also need to pay attention to tariffs and customs clearance issues. If the total amount of combined orders exceeds the personal tax-free amount, you may need to pay additional tariffs. At the same time, you also need to comply with relevant customs regulations and conduct accurate customs declaration and customs clearance procedures to avoid unnecessary losses.
