Just got off the phone with a UPS supervisor who was surprisingly helpful. Here's what he said about my shipment (I'm in the China-Korea-China-Korea loop group with my last update being (re)arrival at Incheon 09/21/2016 8:01 P.M.):
-None of these packages are being scanned individually overseas - only the containers are being scanned
-The container holding my package (along with 2 to 3 thousand other packages) was detained for a security screening. Normally with pre-paid shipments such as these, security screenings aren't done, but one was done on this container for whatever reason.
-Because individual packages are not scanned at this stage, it is possible that the tracking system isn't accurately reflecting the status of the package. To wit - my container may well have departed Korea earlier today or yesterday even though no departure scan is showing in my tracking update.
-I will likely not see any further updates until my container has cleared US customs and my package has been scanned.
-My package will likely be routed through KY before coming to SoCal, and the normal turnaround time from KY to SoCal is 1 day, such that it would be delivered to me in SoCal the day after it arrives in KY.
-My phone is probably already on route from Korea to the US, or is already in the US but has just not yet cleared customs, and as such I should receive it Friday.
-If I want more information regarding what happened overseas, I would have to call international shipping cserv because they have access to more information than domestic shipping cserv.
