ALL good news, thanks for the Update. DHL is the quickest when receiving a shipment from China. They seem better at cutting thru the Red Tape that other Carriers in my dealings.
ALL shipments coming from mainland China first have to go to HONG KONG. China's choke point for control and main international airport. They first go thru China Customs, then after landing in USA at 2 or 3 different Major HUBs, are cleared by US Customs, then they are loaded on a new flight by DHL to reach final destination.
With a tracking number, you can see each step of the process. Usually, the most time consuming is from the time shipped to the time it leaves China. Once on the Plane for USA it goes quickly. Fastest method offered Buy DHL (short of chartering a plane) is usually 3 days from date shipped to arrival/delivery to end customer.
