1. Express Shipping (DHL, UPS, FedEx, EMS):3-10 working days is a good rule of thumb. These services prioritize speed and often offer features like next-day or guaranteed delivery by a certain date (for an additional fee).
2. Air Mail (China Post, Hong Kong Post):7-35 working days, depending on the destination country. This is a more budget-friendly option, but it takes longer because it has lower priority for shipment.
1. Customs Clearance:If customs officials need to inspect your package more thoroughly, it can delay delivery.
2. Distance:Packages traveling longer distances will naturally take longer.
